The tension pressure springs 50, 50 can change the tension pressure applied to the alignment driven sprockets 47, 47 by moving the receiving plates 49, 49 back and forth. By changing according to the average thickness, it is possible to cope with various work conditions.

  The left and right alignment frames 43, 43 are formed with holes 44, 44 in the left-right direction of the fuselage, and the rotation shafts 46, 46 of the alignment driven sprockets 45, 45 are provided through the holes 44, 44. As a result, it is possible to adjust the position by moving the aligned sprockets 45, 45 in the left-right direction. Therefore, when not working and when the foliage is not passing or when the foliage with a small diameter passes, the alignment is performed. The driven sprockets 47, 47 are pressed by the tension springs 50, 50 to the front side and toward the inner side of the machine body, and when the large diameter foliage passes, the aligned sprockets 47, 47 are moved to the outer side of the machine body. Therefore, it is possible to prevent the large-diameter foliage portion from being bitten, and it is not necessary to remove the bitten foliage portion, thereby improving work efficiency.

  In addition, the left-right distance from the conveyance start end side to the conveyance end side of the alignment devices 54L and 54R becomes substantially linear only when a large diameter foliage part passes through and is loaded, so in other cases Is configured to widen the left-right distance of the alignment device from the conveyance start end side toward the conveyance end side, and can prevent the ginseng passing through the left-right interval of the alignment devices 54L, 54R from fluctuating in the left-right direction. Cutting position alignment is performed properly.

  Furthermore, the large diameter foliage part cannot pass between the right and left of the alignment devices 54L and 54R, the cutting position of the carrot foliage part can be prevented from rising too much, and the foliage part can be prevented from remaining in the root part. The work efficiency is improved, the work efficiency is improved, the ginseng is lifted too much, and the root part can be prevented from being cut by the foliage cutting device 61, which will be described later. improves.

  Further, a U-shaped guide cover 51 in a front view covering the contact surfaces of the upper and lower portions of the alignment chains 48 and 48 and the foliage is attached to the plurality of links 48a constituting the alignment chains 48 and 48. The alignment guide body 52 is configured.

  14 (a) to 14 (c), the guide cover 51 is formed with a convex R portion 51a on one side in the front and rear sides and a concave R portion 51b on the other side in the front and rear sides in plan view. And the protrusion part 51c which protrudes toward the convex-shaped R part 51a of the front and back one side of the subsequent guide cover 51 is formed in the front and back other side on the contact surface with the foliage part. In the straight portion, the convex R portion 51a of the following guide cover 51 enters the concave R portion 51b of the front guide cover 51, and the front protruding portion 51c covers the subsequent convex R portion, thereby guiding the guide. Since the space | interval part of covers 51 can be covered, it is prevented that the foliage part of a carrot is bitten by the space | interval part of guide covers 51, and it is not necessary to stop the body and remove the foliage part bitten. , Work efficiency is improved.

  Further, the guide cover 51 has a convex R portion 51a and a concave R portion 51b, and is attached to the links 48a one by one so that the guide covers 51 do not interfere with each other and the alignment chain 48. , 48 can follow the movement of the positioning devices 54L, 54R, and the working efficiency is improved.

  In addition, when the alignment chains 48 and 48 move along the circular arc locus, since the projecting portion 51c is provided, a large interval portion does not occur between the guide covers 51, and thus the ginseng foliage bites into the interval portion. Therefore, it is not necessary to remove the stalks and leaves that have been bitten by stopping the airframe, thereby improving work efficiency.

The alignment guide body 52 may be a U-shaped cross-sectional shape that covers the contact surfaces of the upper surface, the lower surface, and the foliage of the alignment chain 48 instead of the plurality of guide covers 51.
Then, the alignment chains 48, 48 are placed in the winding area of the alignment chains 48, 48 and between the alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47 from the winding area to the foliage contact surface. Left and right tension plates 53L and 53R are attached to the left and right sides of the machine body so that the positions of the left and right tension plates 53L and 53R can be adjusted. .

  The tension plates 53L and 53R are formed with elongated holes in the transmission cases 37 and 37, and the mounting shafts 53a and 53a are attached to the position adjustment by detachable members such as bolts, and a plate is attached to the ends of the mounting shafts 53a and 53a. The bodies 53b and 53b are welded.

  The tension plates 53L and 53R may be provided in a position substantially parallel to the left and right alignment devices 54L and 54R. However, when the tension plate 52R is provided on the front side of the alignment device 53R outside the machine body, the alignment is performed inside the machine body. When the tension plate 52L of the device 53L is provided on the rear side of the machine body with respect to the tension plate 52R of the alignment device 53R, the tension plate 52L or the tension plate when the large diameter foliage passes between the left and right of the alignment devices 54L and 54R. Since the alignment chain 48 and the alignment guide body 52 move to the side without the 52R, even if the diameter of the carrot foliage is large, it can be prevented from being bitten by the alignment devices 54L and 54R, and the aircraft is stopped. It is not necessary to remove the bitten foliage and work efficiency is improved.

  In addition, if the tension of the tension plates 53L, 53R is set to be weaker than the tension of the tension springs 50, 50, the alignment chains 48, 48 will be in an appropriate position when the large-diameter foliage passes and a load is applied. Can be bent and retracted, and can be prevented from being bitten by 54L and 54R, and it is not necessary to stop the body and remove the bitten foliage, thereby improving work efficiency.

  Then, elongated holes are formed in the transmission cases 37, 37 in the vicinity of the alignment drive sprockets 42, 42 and outside the alignment guide bodies 52, 52, and the surfaces of the alignment guide bodies 52, 52 are formed in the elongated holes. The left and right scrapers 55 and 55 for removing pieces and mud of the foliage adhering to the head are attached along the locus of the alignment guide bodies 52 and 52 at the time of position adjustment.

In addition, the scrapers 55 and 55 are arranged in a rearward downward inclined posture, so that it becomes easy to drop the cut ends of the foliage and mud downward.
Then, left and right cutting blade rotation shafts 56 and 56 are attached to the rear positions of the alignment devices 54L and 54R of the left and right first gear units 38 and 38, and left and right bearings 57 and 56 are mounted on the cutting blade rotation shafts 56 and 56, respectively. 57 is attached rotatably. Then, left and right support plates 59, 59 are attached to the left and right bearings 57, 57, and left and right foliage cutting blades 60, 60 are attached to the support plates 59, 59 to constitute a foliage cutting device 61.

  Further, left and right foliage conveyance drive pulleys 62 and 62 are attached to the left and right first output shafts 40 and 40, and the left and right foliage conveyance drive pulleys 62 and 62 are attached to the front side of the machine body above the left and right first gear units 38 and 38 and above the alignment devices 54L and 54R. The foliage driven pulleys 63 and 63 are rotatably attached. Then, the left and right foliage conveying belts 64, 64 are wound around the left and right foliage conveying drive pulleys 62, 62 and the left and right foliage conveying driven pulleys 63, 63 to endlessly form the carrot foliage from the pulling and conveying device 24. Is disposed below the left and right transmission cases 37 and 37 and below the end of conveyance of the pulling and conveying device 24.

  Further, left and right remaining leaf conveyance drive pulleys 66 and 66 are pivotally attached to the upper ends of the left and right first output shafts 40 and 40, and the left and right remaining leaf conveyance driven pulleys 67 and 67 are rotatable above the transmission cases 37 and 37. A plurality of left and right remaining leaf conveyance tension pulleys 68, 68 are attached between the left and right remaining leaf conveyance driving pulleys 66, 66 and the left and right remaining leaf conveyance driven pulleys 67, 67. Then, left and right residual leaf conveyance belts 69, 69 are wound endlessly around the left and right residual leaf conveyance driving pulleys 66, 66, left and right residual leaf conveyance driven pulleys 67, 67, and left and right residual leaf conveyance tension pulleys 68, 68. Thus, the remaining leaf conveyance device 70 that sandwiches the upper part of the foliage and conveys it to the rear of the machine body is configured above the defoliation conveyance device 65.

A foliage shooter 71 for discharging the foliage cut by the foliage cutting device 61 from the end portions of the above-mentioned foliage conveyance device 65 and the remaining leaf conveyance device 70 to the field is provided to constitute the foliage cutting portion D.
With the above configuration, the left and right alignment drive sprockets 42 and 42 are arranged at positions separated from the left and right spacing portions of the alignment devices 54L and 54R through which the foliage passes, so that the alignment drive sprockets 42 and 42 Since it is possible to prevent the stems and leaves from being entangled with the two output shafts 41 and 41 to stop the alignment devices 54L and 54R, the harvesting operation is not interrupted and the work efficiency is improved.

  In addition, since the alignment drive sprockets 42, 42 have a smaller diameter than the alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47, the alignment drive sprockets 42, 42 are further left and right of the alignment devices 54L, 54R. Since it leaves | separates from a space | interval part, it can further prevent that a foliage part gets entangled with the alignment drive sprockets 42 and 42 and the 2nd output shafts 41 and 41, and working efficiency further improves.

  The left and right tension springs 50 and 50 for tensioning the alignment driven sprockets 45 and 45 are provided, so that the left and right alignment chains 48 and 48 are generated when the foliage comes into contact with the alignment devices 54L and 54R. Since the slack can be absorbed and the alignment chains 48 and 48 immediately return to the tensioned state, the alignment devices 54L and 54R ensure that the ginseng foliage even when the foliage portions having different diameters pass continuously. The cutting position of the carrot foliage is properly aligned and the foliage is cut appropriately, and there is no need to remove the foliage in a later process, improving the work efficiency.

  Further, the tension of the tension springs 50, 50 is adjusted by moving the left and right receiving plates 49, 49 in the front-rear direction, so that the growth status of the carrots, the difference in the diameter of the foliage depending on the variety, or the weather and soil quality The tension can be changed appropriately according to the working conditions at the work place, etc., so that the stems and leaves remaining in the carrots are removed in the subsequent process by properly aligning the carrot foliage cutting position and cutting the foliage parts reliably. This eliminates the need for work efficiency.

  Further, the left and right alignment frames 43, 43 are formed with holes 44, 44 in the left-right direction of the machine body, and the rotation shafts 46, 46 having the alignment driven sprockets 45, 45 attached to the holes 44, 44 are movable. In the state where no load is applied, the alignment driven sprockets 45, 45 tensioned by the tension springs 50, 50 move toward the conveyance path of the foliage portion, so that the small diameter foliage portion passes through. Thus, the alignment devices 54L and 54R can receive the foliage portion to properly align the cutting position of the ginseng foliage portion, eliminating the need to remove the foliage portion remaining in the ginseng in a later process, and improving the work efficiency.

  Further, when a large load is applied to the left and right alignment devices 54L and 54R when the large diameter foliage part passes, the alignment driven sprockets 45 and 45 are separated from the movement path of the foliage part along the holes 44 and 44. Since the left and right intervals on the front side of the alignment devices 54L and 54R are widened, the foliage can be prevented from being caught in the interval portions of the alignment devices 54L and 54R, and the aircraft is stopped and bitten. There is no need to remove the foliage and the work efficiency is improved.

  If it is known before harvesting that the carrot foliage has a large diameter, move the alignment driven sprockets 45, 45 away from the left and right of the left and right alignment devices 54L, 54R. If the left and right distances on the upper side in the conveying direction of the alignment devices 54L and 54R are widened, the alignment devices 54L and 54R can be prevented from biting the foliage, and it is necessary to remove the bitten foliage. No work efficiency is improved.

  And, by attaching the guide cover 51 to each of the plurality of links 48a constituting the alignment chains 48, 48 and configuring the alignment guide body 52, the guide cover 51 at an arbitrary location can be freely attached and detached. Even if some of the guide covers 51 are damaged, the proper alignment performance is maintained by simply replacing the guide covers 51 with new ones, and the foliage is appropriately cut, so that the work efficiency is improved.

Moreover, since it is not necessary to replace the entire alignment guide body 52, the cost can be reduced.
Furthermore, since the guide cover 51 can be attached and detached manually without the need for a tool, the replacement work can be easily performed.

  Since the guide cover 51 has a U-shape in front view covering the contact surfaces of the upper and lower surfaces of the alignment chain 48 and the foliage, a space portion is generated between the guide cover 51 and the alignment chain 48. As a result, the foliage is sandwiched between the guide cover 51 and the alignment chain 48, so that ginseng is not aligned at the proper cutting position and the foliage is left uncut, and the foliage is removed in a later process. The work efficiency is improved, the carrot root is prevented from being cut, and the product value of the carrot is improved.

  Further, a convex R portion 51 a and a concave R portion 51 b are formed on the guide cover 51, and the convex R portion 51 a of the subsequent guide cover 51 is brought close to the concave R portion 51 b of the front guide cover 51. By attaching to the alignment chain 48, when the alignment chain 48 moves around the alignment driven sprocket 45 or the like in an arc orbit, the guide cover 51 can move following, so that the alignment devices 54L and 54R Since it operates at a constant peripheral speed, it is possible to properly align the cutting positions of the carrot foliage by receiving the foliage, eliminating the need for removing the foliage remaining in the carrot in a later step, and improving the work efficiency.

  Furthermore, by providing a protruding portion 51c that protrudes toward the convex R portion 51a, when the alignment chain 48 moves around the alignment driven sprocket 45 or the like in an arc orbit, the guide covers 51 ... Since this protrusion 51c covers the space formed between the front and rear, the foliage is sandwiched between the space between the front and back of the guide covers 51, so that the ginseng is not aligned at an appropriate cutting position and the foliage is left uncut. This eliminates the need to remove the foliage in the subsequent process, improves the work efficiency, prevents the carrot root from being cut, and improves the product value of the carrot.

  When the right and left tension plates 53L and 53R are provided in the winding region of the alignment chains 48 and 48, the alignment chains 48 and 48 are pressed from within the winding region. Since the alignment chains 48 and 48 of the portion where the tension plate 53L or the tension plate 53R is not pressed can be retracted in the direction of the alignment drive sprockets 42 and 42, the foliage is bitten between the right and left of the alignment devices 54L and 54R. There is no need to remove the foliage that has been bitten by stopping the airframe, and the work efficiency is improved.

  Further, by providing left and right scrapers 55 and 55 for scrubbing debris and dirt such as mud adhering to the alignment guide bodies 52 and 52 moving on the outer periphery of the alignment drive sprockets 42 and 42, Since it is possible to remove the foreign matter adhering to the alignment guide bodies 52 and 52 at a position away from the moving path of the parts, the foliage fragments are prevented from getting entangled with each part of the alignment devices 54L and 54R. It is not necessary to remove the entangled stem and leaf fragments, and the work efficiency is improved, and the mud mass is prevented from damaging the root of the carrot, thereby improving the product value of the carrot.

  Furthermore, since the attachment positions of the scrapers 55 and 55 can be changed along the elongated holes, the scrapers 55 and 55 are set at optimum positions in accordance with the average diameter of the ginseng stalks and leaves of the field where the harvesting operation is performed. The above-described effect is further improved by reliably removing the debris of the foliage and dirt such as mud from the alignment guide bodies 52 and 52.

  And the leaf shooter 71 which discharges the leaf leaves cut from the carrot by the stem-and-leaf cutting device 61 (the cut stem and leaf portion) to the field seems to discharge the leaves and leaves to the already dug side (the side where the carrot has been harvested). Is provided in a downwardly inclined position, the discharged stems and leaves fall on the carrots on the undigged side (the side where the carrots are not harvested), and the drainage leaves the left and right nipping and conveying belts 19 and 19 and the left and right driven Since it is possible to prevent the harvesting section C from being stopped by being entangled with the pulleys 17, 17, etc., it is possible to prevent the harvesting operation from being hindered, thereby improving the work efficiency and preventing the visibility of the carrots harvested by the fallen leaves falling on the carrots. Can be prevented.

Next, the remaining leaf processing unit E will be described.

Then, a remaining leaf processing belt 74 made of an elastic material such as rubber or urethane is wound around the first remaining leaf processing roller 73a and the second remaining leaf processing roller 73b in an endless manner. Further, a remaining leaf processing roller 75 is attached to the upper portion of the remaining leaf processing belt 74 so that the remaining leaves remaining at the root of the carrot are sandwiched together with the remaining leaf processing belt 74 and rotated to be excised. The remaining leaf processing section E is configured by configuring the remaining leaf processing conveyor 76 that transports the remaining leaves from the outside of the machine body to the left and right inside directions while processing the remaining leaves.

The remaining leaf processing conveyor 76 is inclined about 2 to 5 degrees from the left and right sides of the machine body to the other side.
Thereby, since the carrot which fell is moved by the drive and inclination movement of the remaining leaf processing belt 74, the movement of the carrot does not stop on the remaining leaf processing conveyor 76, and it is necessary to move the carrot stopped manually. No work efficiency is improved. Further, since the residual leaf processing conveyor 76 is slightly inclined (about 2 to 5 degrees), the residual leaf processing conveyor 76 is inclined with respect to the ground even if the aircraft is inclined to the left and right sides depending on the state of the field. Since the carrot remains in a substantially horizontal state, the carrot does not stagnate on the remaining leaf processing conveyor 76 and does not move in the direction opposite to the conveying direction of the remaining leaf processing conveyor 76. There is no need to return it and work efficiency is improved.

  With the above configuration, since the remaining leaf processing roller 75 constituting the remaining leaf processing conveyor 76 cuts off the remaining leaves of carrots cut by the stem and leaf cutting device 61, the operation of manually cutting the remaining leaves after the harvesting operation is omitted. Work efficiency can be improved.

  In addition, the remaining leaf processing belt 74 constituting the remaining leaf processing conveyor 76 is made of an elastic body such as rubber or urethane, so that the remaining leaf processing belt is removed even if carrots fall after the leaves are cut off by the foliage cutting device 61. Since 74 reduces the impact of the drop, the carrot is prevented from being damaged by the impact of the drop, and the quality of the carrot is improved.
