Further, since the rear step 41b is arranged at the rear end of the machine body, it can be used as a step for getting on and off the work step 41, and an operator can easily get on and off.
In the root vegetable harvesting machine 1 of this example, the root vegetables harvested by the harvesting unit 4 are arranged on the left side of the machine body by the transport unit 7 that transports the root vegetables from the left side to the right side on the rear side of the machine body. The root vegetables are transported from the side to the collection unit 6 disposed on the right side of the machine body opposite to the left and right sides, and the root vegetables transported by the transport unit 7 to a location near the rear side of the transport unit 7 are selected. Selection worker boarding parts 41 and 42 on which a worker who performs work is provided, and a control part 3 on which a pilot maneuvering the aircraft boarding is provided at a position near the front side of the conveyance part 7, and the right side part (conveyance) Steering from the lateral side of the sorting operator boarding portions 41, 42 on the outer side of the transfer terminal of the unit 7 in the lateral direction outward side and in the vicinity of the sorting worker boarding portions 41, 42 and the steering portion 3 in the lateral direction outside). It is conveyed by the conveyance unit 7 in the front-rear range over the side part of the unit 3 Because it is configured to have a collection unit 6 that can install a storage bag B that accepts and collects root vegetables, the front and rear length of the fuselage is shorter than before, and the maneuverability is good. In addition, it is possible to install a large-capacity storage bag B installed in the front and rear of the storage bag B installed in the collection unit 6, and the storage bag B is connected to the control unit 3 from the side of the sorting operator boarding units 41 and 42. Since it is installed on the collection unit 6 over the front and rear range over the side portions of the container, the installation and removal operations of the storage bag B to and from the recovery unit 6 can also be performed from above the sorting operator boarding units 41 and 42, The leveling work of the root vegetables accommodated in the operator can be easily performed by the operator who has boarded the sorting operator boarding parts 41 and 42 and the operator who has boarded the control part 3, and the workability is improved.
In addition, since the transport unit 7 is arranged in the vicinity of the front side of the sorting worker boarding units 41 and 42 and in the vicinity of the rear side of the control unit 3, only the operator who has boarded the sorting worker boarding units 41 and 42. In addition, the pilot who has boarded the control unit 3 can also look at the root vegetables transported by the transport unit 7 while facing the rear of the aircraft, and if the operator can afford to control the aircraft, look back at the aircraft and transport it The root vegetables transported by the section 7 can also be selected. In particular, when the transport end portion side of the transport unit 7 is rotated upward to be positioned higher, the transport unit 7 is closer to the control unit 3, and therefore the root vegetables can be easily selected. Further, the seat 42 of the sorting operator boarding portion is positioned in the vicinity of the vertical pivot of the transport unit 7 in the left-right direction of the body, and the seat 12 of the control unit 3 is positioned in the left-right direction of the body. The seat 42 of the operator boarding part is located closer to the transfer terminal part side of the transfer part 7, the seating part of the seat 42 of the sorting operator boarding part is lower, and the seating part of the seat 12 of the control part 3 is higher. Therefore, the worker sitting on the seat 42 of the sorting worker boarding section can turn the transport section 7 up and down with a small amount of vertical movement when the transport end section side of the transport section 7 is turned up and down. The root vegetables transported by the transport unit 7 can be easily selected in the vicinity of the shaft 43 serving as a moving fulcrum. On the other hand, the driver sitting on the seat 12 of the control unit 3 can move the transport unit 7 between maneuvering operations. The conveyance end of the conveyance unit 7 when the conveyance termination part side of the paper is rotated upward and positioned higher It can be performed easily sorting work root vegetables being conveyed side.
The collection unit 6 is arranged in a front-rear range extending from the side portion of the sorting operator boarding portions 41 and 42 to the side portion of the control unit 3 to improve workability. In addition, since the collection unit 6 is disposed on the rear side and the storage bag B is provided, the storage bag B does not prevent the operator from getting in and out of the control unit 3. Further, by providing the collection unit 6 so that the storage bag B is installed in front of the seat 42 of the sorting worker boarding unit, the operator can get on and off the sorting worker boarding units 41 and 42. B is not disturbed.
Further, as shown in FIG. 11, when the transport end portion side is on the rear side of the transport portion 7 that rotates up and down and the sorting operator rises and turns up the transport end portion side, the transport start end side To the end-of-conveyance side, that is, to the right side diagonally forward, or to the right side so that it can be easily seated and sorted (right back). A seat 42 ′ (moved to the left side of the body relative to the seating portion) may be provided. When the seat 42 ′ is provided in this manner, it becomes easy to perform a sorting operation especially when the conveyance end portion side of the conveyance unit 7 is raised and rotated, and is accommodated in the accommodation bag B of the collection unit 6. This makes it easier to confirm the amount of root vegetables to be picked up, so that the lifting operation on the transport terminal end side of the transport section 7 and the lifting operation on the upper opening of the storage bag B can be performed more accurately. It is also easier to perform the operation when throwing away the rear of the aircraft. In addition, the seat 42 can be easily rotated, and sits in a sideways posture (the backrest is positioned on the left side of the aircraft with respect to the seating portion) and sits in a forward-facing posture (the backrest with respect to the seating portion). If the transfer terminal end side of the transfer unit 7 is low, the sorting operation can be easily performed in a forward-facing posture, and the transfer end end side of the transfer unit 7 is When it is high, the sorting operation can be easily performed in the horizontal posture. If the seat on which the worker performing the sorting operation sits in a forward-facing posture is disposed above the remaining leaf processing unit 5, the weight of the sorting worker is set to the left side of the aircraft against the collection unit 6 that requires a large weight on the right side of the aircraft. It can be applied to the side and the weight balance of the aircraft can be improved.
The collection unit 6 includes a support base 39 that supports the bottom of the storage bag B that stores the root vegetables transported by the transport unit 7, and an upper opening of the storage bag B that is installed on the support base 39. A storage bag opening support means 40 is provided for supporting the part in an expanded state. Since the storage bag B supported on the support base 39 is in a state of being widely opened in the front-rear direction and the right outside direction, the size of the storage bag B that can be installed on the support base 39 is A large storage bag that protrudes to some extent from above can be installed, and the storage bag B installed on the support base 39 stores root vegetables and swells relatively large in the front-rear direction and the left-right outer direction. It can also contain root vegetables. Therefore, a large storage bag B can be installed, and a lot of root vegetables can be stored in the storage bag B to perform a harvesting operation, thereby improving work efficiency.
The root vegetable harvesting machine 1 of this example includes a traveling device 2 for self-propelling the aircraft, a maneuvering unit 3 for a piloted operator to steer the aircraft, and extracting and transporting root vegetables from the field, cutting the stems and leaves, and cutting roots. A harvesting section 4 for harvesting the root part of the plant, a collection part 6 for installing a storage bag B for accommodating the harvested root vegetables, and a transport means 5 for receiving root vegetables from the harvesting part 4 and transporting them to the collection part 6 , 7, and the upper and lower storage bag opening support means 40 for supporting the transfer terminal 7 of the transfer unit 7 and the upper opening of the storage bag B installed in the recovery unit 6 in an expanded state. It is the structure provided so that raising / lowering was possible in the same direction.
As a result, when the root vegetables are started to be stored in the empty storage bag B, the root vegetables can be moved by lowering both the transport terminal end of the transport unit 7 and the storage bag opening support means 40 to a low position. If the distance dropped into the storage bag B can be reduced, and the storage amount of root vegetables gradually increases, if the transport terminal end of the transport unit 7 and the storage bag opening support means 40 are raised together, The root vegetables can be stored in the storage bag B until the root bag is full while preventing the root vegetables from overflowing from the storage bag B. In the root vegetable harvesting machine described in the above-mentioned Patent Document 1, the root vegetables are filled without causing the root vegetables to overflow even if the amount of root vegetables increases, while reducing the distance that the root vegetables fall into the storage bag. In order to allow root vegetables to be stored in the storage bag until the state is reached, the support base that supports the bottom of the storage bag is raised and lowered. With such a configuration, the elevating mechanism must be made strong and strong in order to elevate and lower the support base to which a large load is applied, and there is a problem that the elevating mechanism becomes large and costs increase. However, as described above, in this example, the support 39 that supports the bottom of the storage bag B does not move up and down, and the transport of the storage bag opening support means 40 that supports the upper opening of the storage bag B and the transport unit 7 is carried out. Since it is the structure which raises / lowers the termination | terminus part, the strong and strong raising / lowering mechanism like the root vegetable harvesting machine described in the said patent document 1 is not required, and there exists an effect which can aim at simplification of a mechanism. Moreover, in this example, since the accommodation bag opening part support means 40 is attached to the conveyance termination part of the conveyance part 7, and it is set as the structure which raises / lowers the conveyance termination part of the conveyance part 7 with the accommodation bag opening part support means 40, the mechanism further Can be simplified.
In addition, the root vegetable harvesting machine described in Patent Document 1 conveys the root vegetables harvested in the harvesting section in the horizontal direction from the side where the harvesting section is arranged on the sorting conveyor toward the side where the collection section is arranged, And it is set as the structure which collects root vegetables in the collection part arranged at the front upper part by the lifting conveyor and arranged behind the operation part, and there is another conveyor (lifting conveyor) between the sorting conveyor and the collection part. There are disadvantages that the configuration is complicated and the weight of the airframe is increased.
On the other hand, in this example, a step 41 or a seat 42 is provided on the rear side of the body of the transport unit 7 so that an operator can board, and the root vegetables transported by the transport unit 7 are selected. Since it is configured so that the work can be performed, and the transfer terminal portion of the transfer unit 7 and the storage bag opening support means 40 are configured to be movable up and down, the drop distance can be reduced as much as possible when the root vegetables fall into the storage bag. It is possible to simplify the mechanism to prevent the root vegetables from being damaged by reducing the size, and without providing a separate transport unit between the transport unit for performing the sorting operation and the collection unit, the transport unit for performing the sorting operation. Since root vegetables are directly discharged from the conveyance end portion to the collection unit, the configuration of the entire body is simplified, and the weight of the body can be reduced.
The transfer unit 7 is provided so that the transfer end side can be turned up and down around a shaft 43 provided between the transfer start end and the transfer end. Therefore, when the worker located on the rear side of the transport unit 7 performs the sorting operation of the root vegetables transported by the transport unit 7, the entire transport unit 7 does not move up and down and bends at a point in the middle of the transport of the transport unit 7. In this way, since the conveyance end portion side is turned up and down, the operator can perform the root vegetable sorting operation at a location where the vertical movement of the conveyance portion 7 is small, so that the conveyance portion 7 at the location where the sorting operation is performed is low. It is not too high or too high, and it is possible to easily select root vegetables to be transported by the transport unit 7 configured so that the transport end portion side can be moved up and down.
Further, when the shaft 43 serving as a vertical rotation fulcrum on the conveyance end portion side of the conveyance portion 7 is arranged closer to the conveyance start end side than the central position in the conveyance direction of the conveyance portion 7, the conveyance end portion side is raised by a set height. The inclination angle of the transport unit 7 can be reduced, so that the change in the angle of the transport unit 7 at the place where the worker sitting on the seat 42 performs the sorting operation is reduced, and the workability of the sorting operation is improved. In addition, by arranging the shaft 43 so as to be positioned in front of or near the seat 42 on which the worker who performs the sorting work sits, the transport unit 7 is rotated so that the transport terminal end side moves up and down. At this time, the vertical movement amount of the front portion of the seat 42 of the transport unit 7 can be made as small as possible, and the workability of the sorting work performed by the operator sitting on the seat 42 is improved even if the transport unit 7 is rotated up and down. Furthermore, if the shaft 43 is positioned at the front side of the seat 42 and close to the conveyance end portion side, the inclination angle of the conveyance portion 7 when the conveyance end portion side is raised to the set height can be reduced, and the seat The workability of the sorting work performed by the worker sitting at 42 is further improved. In addition, by arranging the shaft 43 so as to be positioned in front of the seat 42 and above the upper surface of the seating portion of the seat 42, the transport unit 7 that performs a sorting operation for the worker sitting on the seat 42 can be provided. Since it is positioned at an appropriate height, the sorting operation can be easily performed.
In addition, the transport unit 7 is provided so that the shaft center is pivotable so that the transport terminal end side moves up and down around the shaft 43 in the front-rear direction, and the shaft 43 is disposed on the remaining leaf processing roller 38 of the remaining leaf processing unit 5. It is arranged so as to be located on the lower side in the conveyance direction (right side of the machine body) of the conveyance part 7 from the front end part, and the conveyance part 7 on the upper side in the conveyance direction of the conveyance part 7 (left side of the machine body) from the front end part of the remaining leaf processing roller 38 The upper surface (conveyance surface) is provided so as to be located below the front end of the remaining leaf processing roller 38. Accordingly, the conveyance end portion side of the conveyance unit 7 moves up and down around the shaft 43 disposed on the lower side in the conveyance direction of the conveyance unit 7 from the front end portion of the residual leaf processing roller 38, and the residual leaf processing roller of the residual leaf processing unit 5. Since the conveyance start end side of the conveyance unit 7 that receives the root vegetables discharged from the front end portion of the body 38 to the front side of the machine body does not move up and down, the root vegetables are successfully transferred from the remaining leaf processing unit 5 to the conveyance unit 7. . When the amount of root vegetables supplied from the remaining leaf processing unit 5 to the conveyance start end side of the conveyance unit 7 becomes larger than the conveyance amount of root vegetables of the conveyance unit 7, the amount of root vegetables is temporarily increased on the conveyance start end side of the conveyance unit 7. Although root vegetables are stored, even if the conveyance end portion side of the conveyance unit 7 moves up and down as described above, it is discharged from the front end portion of the residual leaf processing roller 38 of the residual leaf processing unit 5 to the front side of the machine body. Since the transport start end side of the transport unit 7 that receives the root vegetables does not move up and down, the temporary storage amount of root vegetables on the transport start end side of the transport unit 7 does not fluctuate. There is no increase in the amount of root vegetables on the conveyance start end side of the conveyance unit 7, and the harvesting operation can be performed efficiently in an appropriate state.
When the conveyance terminal end side of the conveyance unit 7 is configured to rotate up and down around the shaft 43, and further, the container bag opening support means 40 is attached to the conveyance termination unit of the conveyance unit 7, as described above. Since the conveyance terminal end of the section 7 can be moved up and down together with the storage bag opening support means 40, a mechanism for simplifying the root vegetables to prevent the root vegetables from being damaged by reducing the fall distance as much as possible when the root vegetables fall into the storage bag. In addition, the conveyance end portion of the conveyance unit 7 can be moved up and down so that the conveyance end portion of the conveyance unit 7 can be lowered below the shaft 43 and can be raised above the shaft 43. When the range is set, the amount of movement of the accommodation bag opening support means 40 in the left-right direction due to the vertical rotation of the conveyance section 7 on the conveyance end portion side can be reduced, and the accommodation bag B containing root vegetables is greatly disturbed to the left and right. I wo n’t be It can be accommodated in the bag B the root vegetables in the. It should be noted that it is more preferable to set the amount of lowering of the conveying end portion of the conveying unit 7 downward from the shaft 43 and the amount of upward raising of the shaft 43 to be substantially the same. Moreover, if the amount by which the conveying end portion of the conveying unit 7 is moved upward from the shaft 43 is set to be larger than the amount by which the conveying end 7 is moved downward from the shaft 43, root vegetables can be added to the storage bag B having a large vertical width. A large amount can be accommodated, and the work efficiency can be further improved.
The storage bag opening portion support means 40 of this example includes front and rear inner support portions 40a and 40a and front and rear outer support portions 40b and 40b that support the left and right and front and rear four portions of the upper opening of the storage bag B. The upper opening can be supported in a wide open state, and the root vegetables released from the conveyance end portion side of the conveyance unit 7 can be accurately accommodated in the accommodation bag B. Moreover, since the intermediate support part 40c which supports the upper opening part of the accommodation bag B below the conveyance termination part of the conveyance part 7 is provided, the upper opening part of the accommodation bag B below the conveyance termination part of the conveyance part 7 Root vegetables released from the conveyance terminal end side of the conveyance section 7 are not spilled and fall outside the accommodation bag B, and the root vegetables can be accommodated in the accommodation bag B more appropriately. Further, the inner support portions 40a, 40a and the intermediate support portion 40c, which are located in the upper opening portion of the storage bag B and support the inner side portion in the left-right direction on the transport end portion side of the transport portion 7, are arranged vertically on the transport end side of the transport portion 7. Since it is attached to the frame on the conveyance end portion side of the conveyance unit 7 that rotates up and down with rotation (specifically, the conveyance unit vertical rotation side plate before and after the rotation roller 37e is rotatably supported). The inner support portions 40a and 40a and the intermediate support portion 40c that support the upper opening of the storage bag B on the transport end portion side of the transport portion 7 rotate up and down along with the vertical rotation on the transport end portion side of the transport portion 7. Thus, the upper opening of the storage bag B on the transport terminal 7 side of the transport unit 7 is securely supported without leaving the transport terminal of the transport unit 7, and the root vegetables are not spilled outside the storage bag B. Storing root vegetables more accurately in the storage bag B It can be.
In this example, each of the inner support portions 40a and 40a, the outer support portions 40b and 40b, and the intermediate support portion 40c is hooked so as to be hooked on a hole or ring provided in the upper opening of the containing bag B. Two hangers 40d formed with the inner support portion 40a and the outer support portion 40b at the left and right end portions are provided on the front and rear sides, and engagement portions formed at the left and right intermediate portions of the front and rear hangers 40d and 40d are provided. The front and rear ends of the hanger support frame 40e extending in the front-rear direction are engaged, and the front and rear ends of the hanger support frame 40e are connected to the frame portion (specifically, the front and rear ends of the transport unit 7). The front and rear mounting arms 40f and 40f extend from the front and rear side portions of the transport end portion of the transport portion 7 to the left and right sides and extend in the front and rear direction. Linked to, the support portions 40a, 40a; and the 40c, is supported on the frame portion of the transfer terminal end portion side of the conveyor 7 up and down rotation; 40b, 40b. Since the front and rear hangers 40d, 40d are engaged with both front and rear ends of the hanger support frame 40e so as to be rotatable about the front-rear direction axis, the transport terminal end side of the transport unit 7 is pivoted up and down to attach arm 40f, Even if 40f is rotated up and down, it can be moved up and down while maintaining a substantially horizontal posture, so that the upper opening of the storage bag B can be properly raised, and the storage bag B storing root vegetables The posture is not greatly disturbed, and the root vegetables can be properly stored in the storage bag B until they are full. A hanger support frame 40e extending from the front side to the rear side of the transport unit 7 on the outer side of the transport terminal part of the transport unit 7 in the front-rear direction of the machine body in plan view is provided at both front and rear ends connected to the hangers 40d and 40d. Since the shape is bent upward so that the gap is located above, the root vegetables discharged from the conveyance end portion of the conveyance portion 7 particularly when the conveyance end portion side of the conveyance portion 7 is lowered to a low position. This prevents the hits from hitting the hanger support frame 40e.

The outer support portions 40b and 40b are attached. When the accommodation bag opening support means 40 ′ is configured in this manner, the attachment member is not disposed between the left and right sides of the rear inner support 40a and the outer support 40b, and is opened to the rear. Therefore, when the worker located on the rear side of the transport unit 7 puts his hand in the storage bag B to work out the root vegetables stored in the storage bag B, the storage bag is opened. The attachment member of the part support means does not get in the way and the operation becomes easy. If the mounting arms 40h, 40h are made of a member that can be elastically deformed by a leaf spring material or the like, the containing bag B can be supported in a more balanced manner.
Moreover, the conveyance terminal part of the conveyance part 7 is located in the state overhanging in the upper side opening part of the storage bag B supported by the storage bag opening part support means 40, 40 ', and the conveyance terminal part of the conveyance part 7 The root vegetables released from the container are appropriately stored in the storage bag B. Moreover, since the conveyance termination part of the conveyance part 7 is located near the machine body inside part of the upper opening part of the accommodation bag B, the upper opening part of the accommodation bag B is located outside the conveyance termination part of the conveyance part 7 in the left-right direction. Since it is in the state opened largely upwards, even if root vegetables are discharged | emitted vigorously from the conveyance termination part of the conveyance part 7, it will be accommodated in the accommodation bag B appropriately. Furthermore, a thin rubber sheet or thick vinyl is placed on the outer side in the left-right direction of the conveyance end portion of the conveyance portion 7 so that root vegetables are not released vigorously from the conveyance end portion of the conveyance portion 7 and jump out of the storage bag B. A flexible sheet 40j such as a sheet is hung and provided so that the root vegetables discharged from the conveyance end portion of the conveyance unit 7 are received by the flexible sheet 40j and appropriately dropped into the storage bag B. be able to. The flexible sheet 40j can be easily attached in a suspended state to the hanger support frame 40e in the accommodation bag opening support means 40, and in the accommodation bag opening support means 40 '. It can be attached to the front and rear mounting arms 40h, 40h in a suspended state.
The collection unit 6 is positioned in a state where it protrudes outward in the left-right direction of the aircraft from the control unit 3, and is configured so as to be vertically rotated by being positioned in a state where the transfer terminal end side of the transfer unit 7 is protruding above the recovery unit 6. . Then, the recovery portion constituting member that protrudes outwardly to the right side from the control portion 3 such as a support member that supports the bottom of the storage bag provided in the recovery portion 6 is attached to the mounting frame 6a, 6a whose axial center is the longitudinal direction with respect to the body frame 17. The recovery portion constituting member is pivoted upward around the attachment shafts 6a and 6a and moved inward of the machine body so that it can be stored. Further, the conveyance terminal end side of the conveyance unit 7 is provided so as to be accommodated in the inner side of the machine body by rotating to the storage raising position further above the upper limit position during the conveyance operation. Thereby, the airframe can be made compact when the airframe is transported / moved or stored. Note that when the transport unit 7 is configured by one endless transport belt 37 and the transport end portion side is turned up and down, a tension roller 37h provided to refract the transport belt 37 in the middle without being slack is transported. Since it is provided only on the lower side of the belt 37, when the conveyance end portion side of the conveyance portion 7 is rotated to the storage lifted position, the folding conveyance belt 37 is rotated while being loosened to the side without the tension roller. Therefore, it can be easily rotated greatly when stored on the conveyance end portion side of the conveyance unit 7, and the machine body can be made more compact. Further, during such storage, if the transfer terminal end side of the transfer section 7 is rotated largely upward, the mounting arms 40f, 40f of the storage bag opening support means 40 and the mounting arms of the storage bag opening support means 40 ' Since 40h and 40h project upward, the mounting arms 40f and 40f; 40h and 40h are provided so as to be foldable, thereby further reducing the size of the machine body. In addition, the collection unit constituting member of the collection unit 6 is configured to be rotated upward and stored so as to enter the lower space on the conveyance end side of the conveyance unit 7 in the state of being rotated to the storage ascending position. The aircraft can be made even more compact.
In this example, an axis drive shaft provided on the conveyance start end side of the conveyance unit 7 is provided so that it can be rotated up and down around the axis 43 in the front-rear direction, and a lift drive device (Fig. In the example, an electric cylinder is used, but a hydraulic cylinder may be provided) 44, and the elevating drive device 44 is provided so that an operator can arbitrarily operate it. The operation operation tool is a foot operation tool 45 that can be operated with a foot by an operator located behind the transport unit 7. In the illustrated example, the pedal type operation tool is provided near the step 41 in front of the seat 42. An operator located behind the transport unit 7 confirms the storage status of the root vegetables in the storage bag B while performing the sorting operation of the root vegetables transported through the transport unit 7 with both hands, and the root vegetables are stored in the storage bag. When it is accommodated near the upper opening of B, the pedal-type operation tool 45 is operated with a foot, and the conveying terminal end side of the conveying unit 7 and the upper opening of the containing bag B are appropriately raised. Therefore, the operator can raise the transport terminal end side of the transport unit 7 and the upper opening of the containing bag B by foot operation without resting the sorting work, and the work efficiency is also improved. Moreover, since this pedal type operation tool 45 performs only the raising operation, the operation is simple and can be operated easily and quickly even during the sorting work, and the operability and workability are improved.
The pedal-type operating tool 45 is provided with a return mechanism that automatically returns to a non-operating position when the foot is removed from the operating tool, and once the pedal-type operating tool 45 is pressed, If it is provided so that the part side rises at the set height and automatically stops, the raising operation on the conveyance end part side of the conveyance part 7 during the sorting operation can be performed quickly and easily, and workability and operability are good. Become. By pressing the pedal-type operation tool 45 once, the conveyance terminal end side of the conveyance unit 7 is raised and the accommodation bag opening support means 40, 40 ′ is raised. If this rise amount is set to 15 to 25 cm, the root vegetables When falling from the conveyance terminal part of the conveyance part 7 into the storage bag B, damage, such as a crack, is hard to occur.
In addition to the pedal-type operation tool 45, a manual operation tool 45a is provided for manually moving the conveyance terminal end side of the conveyance unit 7 up and down to an arbitrary height. Thereby, after raising the set height by the pedal-type operating tool 45, the position of the upper opening of the storage bag B can be adjusted up and down to a more appropriate position, further improving workability and operability. Become good. Further, the raising operation by the pedal type operating tool 45 is performed up to a work raising upper limit position that can be raised during the work, and when the collecting bag 6 filled with root vegetables is discharged out of the apparatus, the work raising upper limit position. When it is further lifted upward and retracted or raised to the storage raised position, it is configured to be performed by the manual operating tool 45a, so that the transport of the transport unit 7 can be performed by operating the pedal operating tool 45 during the sorting operation. It is possible to avoid a situation in which the end portion side is operated above the work rising upper limit position, and the large-sized container bag that is full is lifted and is damaged due to a large load. It should be noted that although the manual operation tool 45a can be operated above the work ascending upper limit position, since the operation is performed at other times than the sorting work, the above-mentioned situation can be easily noticed and avoided. In addition, when the pedal-type operation tool 45 and the manual operation tool 45a are operated simultaneously, the manual operation tool operates with priority. Consciousness concentrates on the movement of the hand rather than the movement of the foot, allowing safe and accurate operation. The manual operation tool 45a is attached to the rear side portion of the transport portion 7 on the transport end portion side, and is used not only for the operator located on the rear side of the transport portion 7 but also for setting the storage bag B or for full storage. Since the bag B is discharged outside the machine, it can be easily operated by an operator located in the vicinity of the collection unit outside the machine, and the operability is improved. Further, the operability is further improved if it is within the reach of the operator located in the control unit 3. A control block diagram showing the above configuration is shown in FIG. 12, in which the control device C, the switch SW1 that is switched by the pedal-type operating tool 45, the switch SW2 that is switched by the manual operating tool 45a, and those switches. A configuration is shown in which a switching signal of SW1 and SW2 is input and the control device C performs control output to the lift drive device 44.
The pedal-type operation tool 45 is configured such that the middle part of the front and rear of the pedal is supported so as to be pivotable about a left-right axis, the front part of the pedal is pivotable downward, and the rear part of the pedal is pivotable downward. In addition, a return mechanism that automatically returns to the forward / backward rotation neutral position is provided so that when the front part of the pedal is turned downward, the return end part side of the transfer part 7 is moved upward, and the rear part of the pedal is turned downward. When the moving operation is performed, if the conveying end portion side of the conveying portion 7 is provided to move downward, the upper and lower direction operations on the conveying end portion side of the conveying portion 7 can be performed only by foot operation. When the position is raised too much, it can be lowered and adjusted up and down to an appropriate position by foot operation during the sorting operation, which further improves the workability and operability. In addition, the raising operation pedal which raises the conveyance termination part side of the conveyance part 7 and the lowering operation pedal which descends can also be provided separately.
In the above description, the lifting operation on the conveyance end portion side of the conveyance portion 7 performed during work is configured to be performed manually by an operator with his or her foot or hand. However, the automatic operation on the conveyance termination portion side of the conveyance portion 7 is performed. As a configuration for raising, the raising operation on the conveyance end portion side of the conveyance unit 7 during the sorting operation is unnecessary, and the workability and operability can be further improved. Specifically, for example, as shown in the control block diagram of FIG. 13, the storage containing root vegetables in contact with the bottom surface of the support base 39 on the lower side of the support base 39 that receives and supports the bottom of the storage bag B As a configuration for providing a sensor WS for detecting the weight of the bag B and drivingly controlling the lifting / lowering driving device 44 based on the detection result of the sensor WS, a conveyance terminal portion of the conveyance unit 7 accompanying an increase in root vegetables in the storage bag B It is set as the structure which operates the raise of a side automatically.
The root vegetable harvesting machine 1 of this example includes a traveling device 2 that allows the aircraft to run forward and backward, a maneuvering unit 3 that a piloted operator steers the aircraft, and pulls and conveys root vegetables from the field to remove the foliage portion. The harvesting unit 4 for cutting and harvesting the root side of the root vegetables, the recovery unit 6 for installing the containing bag B for storing the harvested root vegetables, and receiving the root vegetables from the harvesting unit 4 and transporting them to the recovery unit 6 And a support base 39 that supports the bottom of the storage bag B that stores the root vegetables transported by the transport unit 7 in the collection unit 6. The table 39 is provided so that the posture can be changed to the forward descending posture or the backward descending posture.
Therefore, when the storage bag B of the collection unit 6 is full of root vegetables and the full storage bag B is discharged out of the apparatus, the posture of the support base 39 is changed to the front descending posture or the rear descending posture. As a result, the storage bag B slides and moves to the ground GL on the support base 39 in the inclined posture, so that the operation of lowering the full storage bag B to the ground can be easily performed. In addition, since the storage bag B is lowered to the GL on the ground on the front side or the rear side of the support base 39, after the storage bag B is moved to the ground GL, the support base 39 is set in a forward downward posture. When the storage bag B is lowered onto the ground on the front side, the storage bag B can be completely separated from the support base 39 and can be made to stand on the ground simply by moving the aircraft backward. When the storage bag B is lowered to the ground on the rear side of the support base 39 with the support base 39 in the rearward down posture, the storage bag B is completely separated from the support base 39 and is stood on the ground simply by moving the aircraft forward. Can be put into a state. Therefore, the operation efficiency is improved by a simple configuration and the storage bag B can be quickly and easily moved to the ground.
In this example, the support base 39 includes a base portion 39a having a flat upper surface that supports the bottom surface of the storage bag B, side wall portions 39b and 39b that rise on the left and right sides of the base portion 39a, and a rear side of the base portion 39a. A rear wall portion 39c that rises, and a bucket shape that does not have a rising wall portion on the front side of the pedestal portion 39a and that is open to the front. The bottom portion of the storage bag B is not easily displaced from the support base 39, and the storage bag B can be reliably supported. In addition, the front portion of the base portion 39a forms a slope portion 39d that is in a front-up state, and the forward shift of the storage bag B when the support bag 39 is supported in a substantially horizontal posture. In addition, the posture is changed to the forward and downward state with the front portion of the support base 39 mounted forward, or the posture is changed to the rear downward state with the front portion of the support base 39 mounted rearward. When the storage bag B on the support base is slid and moved on the ground GL, the storage bag B tends to slide down while the support base 39 is changed from the horizontal posture to the forward and downward posture. The storage bag B can be received by the inclined surface portion 39d formed at the front end portion of the 39, so that the storage bag B can be prevented from dropping from the support 39 during the posture change. When the front end of the support base 39 is brought into contact with the ground GL or lowered to a position near the upper side of the ground GL, the slope 39d is inclined forward and downward with respect to the ground GL. The sliding movement to the ground GL is allowed. The support base 39 is detachable. The support base 39 is mounted in a state where an engaging portion 39j provided at the rear part of the support base 39 is engaged with engagement members 46a and 46a fixed to the rotating shaft 46, and the support base 39 is inclined by this engagement. Even in the posture, the support base 39 is prevented from slipping off together with the storage bag B.
In the illustrated example, the posture changing mechanism of the support base 39 is integrally attached to a rear end portion of a support member 39e that supports the detachable support base 39 from the lower side. A moving shaft 46 is pivotally attached to the machine body, and a posture changing operation mechanism that allows the support base 39 to be changed from a substantially horizontal posture to a forward and downward posture by rotating the rotating shaft 46 is connected. Yes. The mounting structure of the rotating shaft 46 on the machine body side is such that the mounting brackets 17a, 17a; 17a, 17a are fixed to the machine body frame 17 and extend back and forth along a frame portion extending forward and backward on the right side portion of the machine body frame 17. A vertical frame 39f is provided, and fixed mounting brackets 39g, 39g, 39g, 39g are connected to the vertical frame 39f via mounting shafts 6a, 6a in the front-rear direction. Further, a horizontal frame 39h extending outward in the left-right direction is fixed to the rear end portion of the vertical frame 39f, and a support plate 39i is attached to the outer end portion of the horizontal frame 39h, and the support plate 39i and the vertical frame 39f are attached. And both left and right end portions of the rotation shaft 46 are rotatably attached. Then, as an attitude change operation mechanism, an arm 47 is integrally attached in the vicinity of the outer end portion of the rotation shaft 46, and an expansion / contraction rod 48 that can be expanded and contracted by rotation of a screw portion is connected to the arm 47. 48, a support portion 49 that supports the rear end side of the 48 is provided, an operation handle 50 that rotates and extends the screw portion of the expansion rod 48 is provided, and the expansion rod 48 expands and contracts when the operation handle 50 is rotated. Thus, the rotation shaft 46 and the support member 39e are rotated together with the arm 47 so that the support base 39 is rotated around the rotation shaft 46. These support base components, including the posture changing operation mechanism, can be turned up around the mounting shafts 6a and 6a and supported by a support provided appropriately on the machine body to be put in a stored state. ing. In addition, since the posture changing operation mechanism is arranged on the rear side of the machine body, the operator boarding the sorting worker boarding portions 41 and 42 can easily operate and the operability is good. In addition, as shown in another example of the figure, a pivot shaft 46 that serves as a pivot axis of the support base 39 is disposed on the front side with respect to the support base 39, so that the support base 39 is changed from a substantially horizontal posture to a rear descending posture. It can also be set as the structure which can be changed.
If the posture changing operation mechanism is configured to be manually operable as described above, the configuration is low and simple. Further, the telescopic drive body 48a such as an electric cylinder or a hydraulic cylinder is used instead of the telescopic rod of the posture changing operation mechanism, and an operation tool such as a switch for operating the telescopic drive body 48a to extend and retract is replaced with the operation handle 50. 3 allows the posture changing operation of the support base 39 to be performed quickly and easily, and the operator who has boarded the control section 3 performs the posture changing operation of the support base 39 to move the containing bag B to the ground. Since the machine body can be moved forward or backward following the operation, the work of lowering the containing bag B to the ground can be performed more quickly, and the workability is further improved.
In the case where the support bag 39 is placed in a rear-down position and the storage bag B is lowered onto the ground on the rear side of the support table 39, when the storage bag B is difficult to slide down on the support table 39, boarding the rear part of the aircraft Thus, the operator can quickly pull the storage bag B behind the machine body.
20 to 24, a loading unit 51 is provided on the front side of the body of the collection unit 6 ′ in which the storage bag B filled with the root vegetables collected by the collection unit 6 ′ is loaded on the body. The upper storage bag B is moved forward and is configured to be movable on the stacking unit 51. If comprised in this way, the container B which became full can be loaded on a body, and a harvesting operation can be continued, the efficiency of a harvesting operation can be improved, and it will become full after continuing a harvesting operation to the field end. The storage bag B can be lowered to the ground, and the full storage bag B can be collected quickly, thereby improving the efficiency of carrying the harvested root vegetables.
In addition, a plurality of support bases 39 that support the storage bag B can be detachably installed from the collection unit 6 ′ to the stacking unit 51, and the support bases 39 can be moved forward from the recovery unit 6 ′ onto the stacking unit 51. The storage bag B can be quickly moved from the collection unit 6 ′ to the stacking unit 51 while being placed on the support base 39, and the stacking unit 51 is filled in a stable state. The storage bag B can be loaded.
A plurality of rollers 52... That can rotate around the horizontal axis from the collection unit 6 ′ to the stacking unit 51 are provided, and the support base 39 is installed on the rollers 52. The storage bag B can be moved to the loading unit 51 with a relatively light force, and the moving mechanism can be simplified.
Further, since the support member 39e ′ for supporting the support base 39 by the stacking portion 51 is provided so that the posture can be changed from a substantially horizontal posture to a forward-downward posture, the storage bag B storing the root vegetables loaded on the stacking portion 51 is placed on the ground. It can be lowered easily and quickly, and the working efficiency is good.
Further, when the support base 39 is moved from the collection unit 6 ′ to the stacking unit 51, a part of the support base 39 (engagement portion 39 j in this example) and an engagement member 46 a ′ provided on the side that supports the support base 39. Is engaged to restrict the forward movement of the support base 39. Therefore, when the support base 39 is changed from a substantially horizontal position to a front-down position by the loading portion 51, the support base 39 together with the containing bag B is supported. Therefore, the storage bag B will not be lowered to the ground with the support base 39 laid down, and the work efficiency will be good.
Compared to the above configuration, the collection unit 6 ′ is not provided with a posture changing mechanism, and the support base 39 that supports the containing bag B is placed on the stacking unit 51 from a substantially horizontal posture to a forward and downward inclined posture. The posture changing mechanism for changing the posture is provided. The specific structure of the posture changing mechanism of the support base 39 employs the same mechanism as the posture changing mechanism of the support base 39 of the collection unit 6 described above. In the figure, the same reference numerals are given to parts having the same function.
In the root vegetable harvesting machine configured as described above, when the storage bag B installed in the recovery unit 6 ′ is filled with the recovered root vegetables, the storage bag B is moved from the recovery unit 6 ′ to the loading unit 51. . At this time, the support base 39 has a structure in which a plurality of rollers 52... Rotatable around the horizontal axis are supported on a plurality of support parts 53 provided from the collection part 6 ′ to the stacking part 51. The support base 39 on which nothing is loaded is removed, and then the operator pushes the storage bag B filled with root vegetables forward, whereby the support base 39 with the storage bag B placed thereon is supported by the support portion 53. These rollers 52 can be easily moved forward on the support portion 53 while rotating the rollers 52. The stacking portion 51 is provided with a support member 39e 'provided with a plurality of rollers 52 that are rotatable around a horizontal axis for supporting the support base 39 from the lower side, and the rear end portion thereof is in the same axial direction as that described above. The rotation shaft 46 is integrally attached to the rotation shaft 46, and the rotation shaft 46 is attached to the rotation shaft 46 by an attitude change operation mechanism constituted by the arm 47, the telescopic rod 48, the support portion 49, and the operation handle 50, as described above. And the support base 39 together with the support member 39e 'is rotated about the rotation shaft 46 so that the posture can be changed from a substantially horizontal posture to a forward and downward tilt posture. In addition, it can also be set as the structure which replaces with these manual operation mechanisms and changes an attitude | position using a drive mechanism. When the full storage bag B is moved from the collection unit 6 ′ onto the stacking unit 51, the storage table 39 previously removed is installed on the collection unit 6 ′. Then, the harvesting operation is continued. After that, when the storage bag B installed in the collection unit 6 ′ is full again, first, the storage bag B on the stacking unit 51 is changed in posture to the front descending state, and the same as described above. take down. Then, the support base 39 of the stacking unit 51 is returned to the original substantially horizontal posture, and the full storage bag B is moved again from the collecting unit 6 ′ onto the stacking unit 51. Further, the posture of the storage bag B moved onto the stacking portion 51 is changed to the front descending state and lowered onto the ground in the same manner as described above. If the work is advanced in this way, the efficiency of the harvesting work can be improved. In addition, after the full storage bag B is moved to the stacking unit 51 and before the storage bag B installed in the collecting unit 6 ′ is full, the storage bag B is loaded into the stacking unit when the machine body reaches the end of the field. 51 can be lowered to the ground. In this way, the collection work of the storage bag B containing the root vegetables can be quickly performed, and the efficiency of the transporting work of the harvested root vegetables can be improved.
The support base 39 installed in the collection unit 6 ′ is provided so as not to be greatly displaced back and forth between the stopper 54 provided on the rear side and the support base 39 installed in the stacking unit 51. The support base 39 installed on the stacking unit 51 supports a part of the support base 39 (in this example, the engaging portion 39j) and the support base 39 so that the support base 39 does not fall off when the posture is changed to forward and downward. Since the forward movement of the support base 39 is restricted by the engagement with the engaging member 46a ′ provided on the side to be supported, the support base 39 installed in the recovery section 6 ′ is shifted to the front side to the stacking section 51. Even if it hits the installed support base 39, it does not shift further forward, and the mechanism for preventing the shift of the support base 39 of the stacking unit 51 also serves to stop the front of the support base 39 installed in the collection unit 6 '. Thus, the configuration is simplified. Further, the right and left guides 55 and 55 provided in the support part 53 are used to stop the support base 39 installed in the collection unit 6 ′ in the left and right direction. Stopping is performed by left and right guides 56, 56 provided on the support member 39e '.
As shown in FIG. 8, defective root vegetables selected and extracted from the root vegetables transported by the transport unit 7 are disposed on the front side of the seat 42 of the boarding units 41 and 42 for the sorting workers and on the rear side of the transport unit 7. An input portion of a drop passage 57 that guides the drop to the farm is arranged.

It does not take the foliage that is dropped and discharged by the person, and the work can be done comfortably. In addition, the lower part 58a of the leaf shooter 58 from which the foliage is dropped and discharged extends the lower part of the leaf shooter 58 so that the lower discharge portion 58a is located below the seat 42 of the boarding portions 41 and 42 for sorting workers. For example, the leaflet shooter 58 is provided so as not to protrude too much to the rear of the machine body, while preventing the fallen and discharged stems and leaves from being placed on the operator sitting on the seat 42, so that the machine body can be made compact. Further, a remaining leaf processing section 5 is arranged on the left side of the seat 42 of the sorting sections 41 and 42 for sorting workers, and the first conveyor 36 located at the right side of the machine body from the remaining leaf processing roller 38 is configured to perform the remaining leaf processing. The foliage removed by the roller 38 is conveyed, and the foliage falls from the conveyance end. The lower part of the conveyance termination part of the 1st conveyor 36 is opened, and the foliage part which fell from the conveyance termination part of the 1st conveyor 36 passes the opening part, and falls to a farm field. In addition, you may provide so that the upper side of the remaining leaf process part 5 may be covered with the cover 5a for safety. In this case, the cover 5a is extended to the right side of the conveyance end portion of the first conveyor 36 and to the lower side thereof, and the foliage portion that has fallen from the conveyance end portion of the first conveyor 36 is applied to the field. In order to make it fall, it serves as a guide guided to the opening formed below.

By hooking the support in this hole, the upper opening g of the storage bag B can be supported in an expanded state. Further, one or a plurality of holes k, k are provided between the left and right holes on the left and right sides. As a result, a support is hooked into the holes j, j, j, j on both the left and right sides and the upper opening g of the storage bag B is expanded and supported, and one side of the storage bag B is located above the upper opening g. The transport section (on the root vegetable harvesting machine, the transport end section side of the transport section 7) is arranged so as to enter from the side (front and rear side), and the material discharged from the transport section is properly accommodated The upper opening between the left and right holes is loosened by supporting the hooks in the holes k, k provided between the left and right holes so as to enter the bag B. Thus, it is possible to reliably prevent the material discharged from the transport unit from spilling out of the storage bag B. In addition, the support which expands and supports the upper side opening part g is hooked in the said hole from the inner side of the storage bag B. FIG. At this time, each upper lid d, d, d, d is taken out so as to roll outside the bag (outside each side part a, a, b, b) and inside the containing bag B together with what the upper lid contains. Make sure that it does not become difficult to pull out the upper lid later. In place of the hole, a loop may be sewn (not shown). FIG. 26 shows a state in which the root vegetable harvester is supported by the storage bag opening support means 40 or the hook-shaped support 40b of 40 ′.
Further, the bottom c is formed with a lower opening m that opens a part on the center side of the bottom, and further, double bottom lids n and p that close the opening m are provided. The bottom lids n and p are passed through a string q like an upper lid, and the string q is tied so that the lower opening m is not easily opened. The lower opening m unwinds the string q below the bottom c of the lifted storage bag B when the storage bag B is lifted with a fork of a forklift and the stored bag is discharged out of the bag. The contents can be quickly and easily discharged.
Also, as shown in FIG. 29, if the strings r, r, and bands that support the side portions a, a, b, and b facing each other are provided inside the bag, the containing bag swells and it becomes difficult to stand on the ground. Can be prevented. As shown in FIG. 27, when two hangeres h ′, h ′, h ′, h ′ are arranged side by side on the side portions a, a facing each other, fork F in which a horizontally long storage bag is arranged in two forklifts. , F can be lifted so as not to tilt by thrusting into each of the hangeres h ′, h ′, h ′, h ′.
Further, as shown in FIGS. 25 and 30, when a band s with a gap s ′ into which a stick ST or the like is inserted is provided around the storage bag B, a support stand for the root vegetable harvesting machine is provided. After moving the storage bag B to the ground by tilting 39, when the machine body is moved away from the storage bag B, the gap s ′ of the band s is prevented so that the storage bag B is not dragged and moved. You can stop the drag by sticking the stick ST. In addition, as shown in FIG. 31, when the support bag 39 of the root vegetable harvesting machine is tilted and the storage bag B is moved to the ground, the hanger h and h are attached so that the storage bag B does not fall in the tilt direction.
