Description

  The present invention relates to a combine having a cutting part at a front portion of a traveling machine body and having a side divider on one lateral side of the cutting part.

2. Description of the Related Art Conventionally, a combine having a side divider on one side portion of a cutting unit is known. The side divider is designed to prevent the traveling machine body moving forward from cutting the unharmed cereals on one side of the machine and cutting it with the traveling crawler. ). For example, Patent Document 1 discloses an example of this type of side divider.
Japanese Patent No. 3633861

The side divider described in the above-mentioned patent document 1 includes a pair of front and rear weed folds connected to each other via a pivoting member, and an intermediate link ridge that supports the intermediate portion of the weed folds on a traveling machine body. Have. The intermediate link rod includes a pinion gear driven by an electric motor and a rack gear driven by meshing with the pinion gear. Then, when the pinion gear and the rack gear are engaged with each other, the intermediate link rod slides to move, and the working position where the pair of front and rear weed rods project outward in the lateral direction of the traveling machine body, the cutting part and the work machine body are close to each other. The position can be changed to the storage position.
In addition, the linkage state of the pinion gear and the rack gear is maintained by an urging mechanism, and when the side divider is overloaded by, for example, interfering with a kite, the pinion gear resists the urging force of the urging mechanism. And the linkage of the rack gear are released, and the posture of the front side divider is changed to the storage position.
With such a configuration, even if the side divider interferes with the heel during the dredging operation, the side divider is automatically repositioned from the working position to the storage position, so that the side divider can be prevented from being deformed.

  However, if the above-described configuration of the side divider is employed, if the side divider comes into contact with the heel and is temporarily stored in the storage position during the cutting operation, the posture is maintained. Therefore, if the side divider needs to move away from the interference caused by the saddle and return to the work position after that, an operation to change the side divider to the work position must be performed each time, which greatly increases the burden on the operator. There was a problem of being.

  The present invention has been made in view of the above circumstances, and automatically avoids the side divider from interfering with and deforming the hook during the work, and the side divider is separated from the interference caused by the hook. Another object of the present invention is to provide a combine that can automatically return the position of the side divider to the working position.

  The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.

  That is, in claim 1, a cutting part provided at the front part of the traveling machine body, a front side divider provided so as to extend in the front-rear direction on a lateral side part of the cutting part, a cutting part body, and the front part A combine provided with a side divider and comprising an operating device capable of changing the front side divider to a working position in which the front side divider is extended laterally outward of the cutting unit main body and a storage position adjacent to the cutting unit main body. The actuating device is disposed between the actuator, the actuator and the front side divider, and is linked to the reaping portion main body. A support member that is movably supported inward in the direction, and a biasing member that biases the actuator to a predetermined position via the support member.

  According to a second aspect of the present invention, the support member includes a bracket that protrudes laterally outward from the reaping portion main body, and a plate-like base that is pivotally attached to the bracket at a substantially central portion. The urging member is interposed between the other end of the pedestal of the support member and the harvesting part main body.

  According to a third aspect of the present invention, the support member includes a bracket projecting laterally outward from the reaping portion main body, and a pedestal supported by the bracket so as to be slidable laterally outward or laterally inside. The actuator is fixed to a pedestal of the support member, and the urging member is provided integrally with the support member.

  According to the combine according to claim 1, when an external force is applied, for example, when the front side divider in the working position interferes with the rod, the front side divider is cut off without applying a large load to the actuator of the actuator. It can be moved to escape to the main body side. Therefore, deformation and damage of the front side divider due to such an external force can be avoided. Further, when such an external force stops working, it is possible to automatically return the actuator to a predetermined position and thus the front side divider to the original working position by the urging force of the urging member. Therefore, an operation for returning the side divider to the work position becomes unnecessary, and the operator's work load can be reduced.

  According to the combine which concerns on Claim 2, an actuator can be comprised simply. Moreover, the attaching work of the urging member can be easily performed.

  Next, detailed configurations of the side divider 100 and the actuator will be described with reference to FIG.

  The side divider 100 is used to push the uncut grain corn on one side of the combine 1 laterally outward so that it does not get caught in the cutting unit 20 or stepped on the traveling unit 10 during the cutting operation. It is. The side divider 100 is arranged on the lateral side of the traveling machine body including the cutting part 20, the machine body frame 2 and the traveling part 10, in the present embodiment, on the left side part, and the position is changed between the working position and the storage position. It extends in the front-rear direction as possible.

  The side divider 100 includes a front side divider 110 and a rear side divider 120. The front side divider 110 includes a first weed basket 111 and a second weed basket 112. However, the front side divider 110 may not be provided with the second weed cocoon 112 but may be composed of only the first weed cocoon 111.

  The first weed pod 111 is mainly disposed in the vicinity of the left side of the cutting unit 20, extends in the front-rear direction so as to be continuous with the weeding tool 21, and the rear end portion is laterally outer than the front end portion. It is inclined with respect to the cutting part 20 so as to be located on the left side of the traveling machine body. The first weed bush 111 is pivotally attached to the left side of the cutting unit 20 at the front end so as to be horizontally rotatable by a vertically-supported pivot shaft 113, and is connected to the second weed bush 112 at the rear end. .

  A stay 106 is provided at the rear portion of the first weed basket 111 so as to protrude inward in the lateral direction. The first weed basket 111 is linked to the motor 151 via the linkage mechanism by the stay 106, as will be described later.

  The second weed cage 112 is disposed in the vicinity of the left side portion of the traveling aircraft body, extends in the front-rear direction, and is located with respect to the traveling aircraft body such that the rear end portion is located on the inner side in the aircraft lateral direction than the front end portion. It is inclined. The second weed cage 112 is bent in the middle of the front and rear, and is pivoted horizontally by a pivoting member comprising a vertical pivot shaft 114 at the rear end of the first weed cage 111 at the front end. Attached to the rear side divider 120 at the rear end.

  The rear side divider 120 is disposed in the vicinity of the left side portion of the traveling aircraft body and extends in the front-rear direction along the traveling aircraft body. The rear side divider 120 is bent at the front end portion and the rear end portion, fixed at the front end portion to the left front portion of the traveling aircraft body, and fixed at the rear end portion to the left rear portion of the traveling aircraft body. Then, the rear side divider 120 protrudes from the traveling machine body by a predetermined width outward in the lateral direction so that the front and rear halfway portions are substantially parallel to the traveling machine body.

  A ring member 115 is loosely fitted to the middle part of the rear side divider 120 so as to be slidable in the front-rear direction. The ring member 115 is connected to the rear end portion of the second weed cage 112, and the rear end portion of the second weed cage 112 is moved back and forth along the front and rear middle portion of the rear side divider 120 via the ring member 115. It can slide in the direction.

  Thus, the front side divider 110 is configured to connect the first weed cage 111 and the second weed cage 112 so that they can be bent forward and backward by the pivot shaft 114. By changing the bending angle formed by the weed ridge 112, the extent of the outward projecting in the lateral direction can be changed.

  On the other hand, the actuating device is arranged between the front side divider 110 and the cutting unit main body (cutting frame 25), and can change the position of the front side divider 110 between the working position and the storage position. The actuating device includes a support member including the bracket 101 and the pedestal 140, a motor 151 as an actuator, a linkage mechanism including the arm 150 and the intermediate link rod 130, and an urging member 160.

  The bracket 101 of the support member is fixed to the harvesting part main body (the harvesting frame 25) at the base end part and protrudes outward in the lateral direction. However, each member including the bracket 101 can be disposed not on the cutting unit 20 but on the traveling machine body.

  The pedestal 140 of the support member is made of a substantially rectangular plate-like member, and is arranged on the inner side in the lateral direction (side closer to the traveling machine body) than the front side divider 110. The pedestal 140 is extended so that the longitudinal direction thereof is the front-rear direction, and is pivotally attached to the distal end portion of the bracket 101 at the center by a vertically-supporting pivot shaft 141 so as to be horizontally rotatable.

  The motor 151 is fixed to the rear end portion of the pedestal 140 so that the drive shaft 152 protrudes upward. The motor 151 is connected to a controller provided at a desired position of the cutting unit 20 or the traveling machine body, and can be controlled to be driven or stopped by the controller in accordance with the operation of the operation tool arranged in the control unit 90. Is done. Or you may comprise so that the motor 151 can be directly forward-rotated or reverse-rotated with the said operation tools, such as a switch provided in the control part 90. FIG.

  The linkage mechanism is interposed between the motor 151 and the first weed ridge 111. In other words, the arm 150 is disposed horizontally above the motor 151, and is fixed to the longitudinal drive shaft 152 of the motor 151 at one end, so that the arm 150 can be horizontally rotated integrally with the drive shaft 152. The intermediate link rod 130 is pivotally attached to the stay 106 of the front side divider 110 at one end so as to be horizontally pivotable by a pivot shaft 105 which is vertically oriented, and is vertically oriented to the other end of the arm 150 at the other end. The pivot shaft 131 is pivotally mounted so as to be horizontally rotatable.

  In this way, when the motor 151 is driven, the arm 150 and the intermediate link rod 130 are operated to move the first weed rod 111 (front side divider 110) laterally outward or inward, and the position thereof is the cutting unit 20. It is possible to change to a working position projecting laterally outside or a storage position close to the cutting unit 20 and the traveling machine body. In addition, by the movement of the first weed pod 111, the second weed pod 112 is also moved laterally outward or inward while changing the bending angle formed with the first weed pod 111.

  And the biasing member 160 comprised with the spring etc. is interposed between the front-end part of the base 140, and a cutting part (cutting frame 25) main body. The urging member 160 urges the front end portion of the pedestal 140 inward in the lateral direction, and at the same time abuts against a stopper 142 projecting upward from the tip end portion of the bracket 101, so that the pedestal 140 is moved in the longitudinal direction. Is held at a predetermined rotation position so as not to be horizontally rotated.

  Thus, by holding the pedestal 140 in the predetermined rotation position, as shown in FIG. 3, the motor 151 on the rear end of the pedestal 140 is held in the predetermined position. The motor 151 is driven and controlled in a state where it is held at this predetermined position during a normal cutting operation in which an external force described later does not act on the front side divider 110.

  Below, the operation | movement aspect of the side divider 100 which concerns on this embodiment, and the said operating device is demonstrated with reference to FIG. 4 and FIG.

  First, at the time of cutting work or at the start / end of work, the operator operates the operation tool with the control unit 90 or automatically in conjunction with the work clutch lever using a sensor or the like. A case where the posture of the divider 110 is selectively changed to the work position or the storage position will be described with reference to FIG.

  As shown in FIG. 4A, in the state where the front side divider 110 is held in the storage position in accordance with the traveling or stopping of the combine 1, the front side divider 110 is set to the working position by the operation tool. When the operation is performed, the motor 151 is driven at a predetermined position, and the drive shaft 152 is rotated by a predetermined amount (180 degrees in this embodiment) in the forward rotation direction (or the reverse rotation direction). At that time, the arm 150 is horizontally rotated clockwise (in the direction of arrow R in FIG. 4A) around the drive shaft 152 as the drive shaft 152 rotates, and the intermediate link rod 130 is moved to the arm 150. With horizontal rotation, the body frame 2 is horizontally moved outward in the lateral direction.

  As the intermediate link rod 130 moves, the first weed rod 111 is horizontally rotated about the pivot shaft 113 outward in the lateral direction. At this time, the second weed cocoon 112 is interlocked with the first weed cocoon 111, and the rear end portion is slid forward along the rear side divider 120 to make the angle formed with the first weed cocoon 111 smaller. It is moved to the outside in the lateral direction while changing in this way.

  When the drive shaft 152 of the motor 151 is stopped after being rotated by a predetermined amount, the first weed cage 111 is thereby held at a preset work position. As a result, as shown in FIG. 4 (b), the work positions at which the postures of the first weed cage 111 and the second weed cage 112, that is, the position of the front side divider 110 protrude most outward in the lateral direction of the aircraft. Thus, it is held at this working position. In this way, the position of the front side divider 110 is changed from the storage position shown in FIG. 4A to the work position shown in FIG. 4B.

  Further, as shown in FIG. 4B, when the operation for bringing the front side divider 110 into the storage position is performed by the operation tool while the front side divider 110 is held at the working position, the motor 151 is moved. Driven at a predetermined position, the drive shaft 152 is rotated by a predetermined amount (180 degrees in this embodiment) in the reverse rotation direction (or forward rotation direction). At that time, the arm 150 is horizontally rotated in the counterclockwise direction (the direction of the arrow L in FIG. 4B) around the drive shaft 152 as the drive shaft 152 is rotated, and the intermediate link rod 130 is laterally moved. Move horizontally in the direction.

  Therefore, the rear portion of the first weed rod 111 is pulled by the intermediate link rod 130, and the first weed rod 111 is horizontally rotated inward in the lateral direction around the pivot shaft 113. At this time, the second weed cocoon 112 is interlocked with the first weed cocoon 111, and the rear end portion is slid rearward along the rear side divider 120 to increase the angle formed with the first weed cocoon 111. It is moved inward in the horizontal direction while changing in this way.

  Then, when the drive shaft 152 of the motor 151 is stopped after being rotated by a predetermined amount, as a result, the position of the first weed cage 111 and the second weed cage 112, that is, the position of the front side divider 110 is changed. As shown in FIG. 4A, the storage position is close to the cutting unit 20 and the traveling machine body and is held at this position. In this way, the position of the front side divider 110 is changed from the work position shown in FIG. 4B to the storage position shown in FIG.

  Next, when the front side divider 110 comes into contact with the reed at the time of cutting operation at the heel and the like, and the external force acts on the front side divider 110, the position of the front side divider 110 is changed from the working position to the storage position. The mode to be changed will be described with reference to FIG.

  At the time of the cutting operation, as shown in FIG. 5A, the front side divider 110 is in contact with the scissors and the like while the front side divider 110 is held at the work position, and the external force F acts on the front side divider 110 inward in the lateral direction. In this case, the first weed rod 111 is horizontally rotated inward in the lateral direction around the pivot shaft 113 by the external force F. At this time, the second weed cocoon 112 is interlocked with the first weed cocoon 111, and the rear end portion is slid rearward along the rear side divider 120 to increase the angle formed with the first weed cocoon 111. In this way, it is horizontally moved inward in the lateral direction.

  Further, the intermediate link rod 130 is pushed by the rear portion of the first weed rod 111 and is moved horizontally in the lateral direction. Here, since the motor 151 is stopped, the motor 151 is pushed together with the base 140 via the arm 150. Therefore, the pedestal 140 is rotated counterclockwise in FIG. 5A around the pivot shaft 141 against the urging force of the urging member 160, and the motor 151 is moved laterally inward from a predetermined position. Moved to.

  In this way, the first weed basket 111 can be horizontally rotated from the original position in the lateral direction, and the front side divider 110 is moved from the working position shown in FIG. 5A to FIG. 5B. Is changed to the storage position shown in FIG.

  From the above state, when the front side divider 110 moves away from the bag or the like as the combine 1 advances, and the external force F does not act on the front side divider 110, the base 140 is pulled by the biasing force of the biasing member 160, It is horizontally rotated clockwise around the support shaft 141 in FIG. At that time, the motor 151 on the rear end portion of the pedestal 140 is horizontally moved toward a predetermined position outside in the lateral direction, and the arm 150 is horizontally moved together with the intermediate link rod 130 outward in the lateral direction.

  Therefore, the rear portion of the first weed rod 111 is pushed by the intermediate link rod 130, and the first weed rod 111 is horizontally rotated about the pivot shaft 113 outward in the lateral direction. At this time, the second weed cocoon 112 is interlocked with the first weed cocoon 111, and the rear end portion is slid forward along the rear side divider 120 to make the angle formed with the first weed cocoon 111 smaller. In this way, it is moved horizontally outward in the lateral direction.

  In this way, the first weed basket 111 can be horizontally rotated outward in the lateral direction toward the original position, and the front side divider 110 is moved to the original work position as shown in FIG. Returning to FIG. 4 (b).

  Below, the structure of the combine 200 based on other embodiment of this invention is demonstrated with reference to FIGS. 6-8. However, in the following description, the description of the parts that are substantially the same as those of the above-described embodiment will be omitted with the same reference numerals as those in the case of the combine 1 being applied to the respective members, and different parts will be mainly described.

  As shown in FIG. 6, the operating device is provided between the front side divider 110 and the cutting unit main body (cutting frame 25), and can change the position of the front side divider 110 between the working position and the storage position. is there.

However, each member including the bracket 301 can be disposed not on the cutting unit 20 but on the traveling machine body. A groove-like rail portion 302 is formed in the bracket 301 along the longitudinal direction.

  The pedestal 340 of the support member is made of a plate-like member, and is arranged on the inner side in the lateral direction (side closer to the traveling machine body) than the front side divider 110. A convex portion 340 a is formed at the bottom of the pedestal 340, and this is fitted to the rail portion 302 of the bracket 301. Thus, the pedestal 340 is supported by the bracket 301 so as to be slidable along the rail portion 302.

  Then, an urging member 360 made of a spring or the like is inserted inward in the lateral direction with respect to the convex portion 340 a in the rail portion 302 so as to come into contact with the convex portion 340 a of the pedestal 340 at one end portion, and integrated with the bracket 301. Provided. Due to the urging force of the urging member 360, the pedestal 340 is urged laterally outward and held at a predetermined position on the laterally outermost end of the rail portion 302.

  The motor 351 is fixed to the upper part of the pedestal 340 so that the drive shaft 352 protrudes upward, and is held at a predetermined position via the pedestal 340 urged by the urging member 360. The motor 351 is connected to the operation tool disposed in the control unit 90 via a controller, and can be driven forward or reversely according to the operation of the operation tool. Here, the motor 151 is driven and controlled in a state of being held at a predetermined position during a normal cutting operation in which an external force described later does not act on the front side divider 110.

  The linkage mechanism is interposed between the motor 351 and the first weed fence 111. That is, the arm 350 is disposed horizontally above the motor 351 and is fixed to the longitudinal drive shaft 352 of the motor 351 at one end, and can be horizontally rotated integrally with the drive shaft 352. The intermediate link rod 330 is pivotally attached to the stay 106 of the front side divider 110 at one end so as to be horizontally rotatable by the pivot shaft 105 which is vertically oriented, and is vertically oriented to the other end of the arm 350 at the other end. Is pivotally mounted on a pivot shaft 331 so as to be horizontally rotatable.

  Thus, when the motor 351 is driven, the arm 350 and the intermediate link rod 330 are actuated to move the first weed rod 111 to the laterally outer side or the inner side, and the position of the first weeding rod 111 is projected to the laterally outer side of the cutting unit 20. The working position or the storage position close to the cutting unit 20 and the traveling machine body can be changed. In addition, by the movement of the first weed pod 111, the second weed pod 112 is also moved laterally outward or inward while changing the bending angle formed with the first weed pod 111.

  Below, the operation | movement aspect of the side divider 300 which concerns on this embodiment is demonstrated with reference to FIG. 7 and FIG.

  The front side divider 110 is automatically operated when the operator operates the operation tool with the control unit 90 at the time of cutting work or at the start / end of the work or in conjunction with the work clutch lever using a sensor or the like. In the case of selectively changing the position to the work position or the storage position, as shown in FIG. 7, the operation mode is substantially the same as that of the combine 1 (see FIG. 4).

  Next, when the side divider 300 comes into contact with the cocoon or the like at the time of cutting work at the edge of the hook, and the external force is applied to the side divider 300, the position of the side divider 300 is changed from the working position to the storage position. The aspect will be described with reference to FIG.

  As shown in FIG. 8 (a), when the external force F works inward in the lateral direction when the front side divider 110 is held in the working position and the external force F works inward in the horizontal direction, The eaves 111 are horizontally rotated about the longitudinal pivot shaft 113. The second weed ridge 112 is interlocked with the first weed ridge 111, and the rear end is slid rearward along the rear side divider 120 to change the angle with the first weed ridge 111 to be larger. It is moved inward in the horizontal direction.

  Further, the intermediate link rod 330 is pushed by the rear portion of the first weed rod 111 and moved horizontally in the lateral direction. Here, since the motor 351 is stopped, the motor 351 is pushed together with the base 340 via the arm 350. Therefore, the pedestal 340 is horizontally moved inward in the lateral direction against the urging force of the urging member 360 along the rail portion 302, and the motor 351 is moved inward in the lateral direction from a predetermined position.

  In this way, the first weed fence 111 can be horizontally rotated from the original position in the lateral direction, and the front side divider 110 is moved from the work position shown in FIG. 8A to FIG. 8B. Is changed to the storage position shown in FIG.

  From the above state, when the front side divider 110 moves away from the bag or the like as the combine 200 advances, and the external force F no longer acts on the front side divider 110, the pedestal 340 is pushed out by the urging force of the urging member 360, and the lateral direction It is moved horizontally along the rail portion 302 to the outside. At that time, the motor 351 fixed to the upper part of the pedestal 340 is horizontally moved toward a predetermined position outside in the lateral direction, and the arm 350 is horizontally moved together with the intermediate link rod 330 outward in the lateral direction.

  Therefore, the rear portion of the first weed rod 111 is pushed by the intermediate link rod 330, and the first weed rod 111 is horizontally rotated about the pivot shaft 113 outward in the lateral direction. At this time, the second weed cocoon 112 is interlocked with the first weed cocoon 111, and the rear end portion is slid forward along the rear side divider 120 to make the angle formed with the first weed cocoon 111 smaller. It is moved to the outside in the lateral direction while changing in this way.

  In this way, the first weed basket 111 can be moved horizontally outward in the lateral direction toward the original position, and the front side divider 110 can move to the original work position (see FIG. 8A). 7 (b)) is restored.

  As described above, the combine 1 according to one embodiment of the present invention and the combine 200 according to another embodiment include the cutting unit 20 provided at the front portion of the body frame 2 (running vehicle body) and the side of the cutting unit 20. A front side divider 110 provided on the side portion so as to extend in the front-rear direction, a working position for projecting the front side divider 110 laterally outward of the cutting unit main body, and a storage position close to the cutting unit main body And an actuator that is arranged between the motors 151 and 351 as actuators and between the motors 151 and 351 and the front side divider 110 and that links both of them. A linkage mechanism including 150 and 350 and intermediate link rods 130 and 330, and a motor attached to the cutting body (cutting frame 25). A support member including brackets 101 and 301 and pedestals 140 and 340 that movably support 51 and 351 laterally outward or laterally inside, and motors 151 and 351 are biased to predetermined positions via the support members. The urging members 160 and 360 are provided.

  As a result, when the front side divider 110 is in contact with a hook or the like with the posture set as the working position during the cutting operation, and external force is applied to the front side divider 110, the motors 151 and 351 are moved from the working position to the cutting unit. By moving to the main body side, the front side divider 110 is allowed to escape in the direction in which the external force acts, and the position can be changed from the working position to the storage position. Further, when the front side divider 110 is moved away from the bag or the like in a state where the front side divider 110 is set to the storage position by an external force, and the external force does not act on the front side divider 110, the motors 151 and 351 are driven by the biasing force of the biasing members 160 and 360. As a result, the position of the front side divider 110 can be changed from the storage position to the original work position.

  Therefore, when the front side divider 110 in the work position interferes with the heel and an external force is applied, the front side divider 110 is moved to the cutting unit main body (cutting unit) without applying a large load to the motors 151 and 351 of the actuator. The frame 25) can be moved so as to escape. Therefore, deformation and damage of the front side divider 110 due to such an external force can be avoided.

  Further, when such an external force is not applied, the motors 151 and 351 are automatically returned to predetermined positions and the front side divider 110 is automatically returned to the original working position by the biasing force of the biasing members 160 and 360. It becomes possible. Therefore, an operation for returning the side dividers 100 and 300 to the work position becomes unnecessary, and the work burden on the operator can be reduced.

  Further, the support member of the combine 1 according to the embodiment of the present invention includes a bracket 101 projecting laterally outward from the harvesting portion main body (reaching frame 25), and pivotally attached to the bracket 101 at a substantially central portion. The motor 151 is fixed to one end of the support member pedestal 140, and the urging member 160 includes the other end of the support member pedestal 140 and the cutting part main body ( The cutting frame 25) is interposed.

  As a result, the motor 151 can be moved laterally outward or inward with a simple structure, and the actuator can be simply configured. Further, the attaching operation of the urging member 160 can be easily performed.

  Further, the support member of the combine 200 according to another embodiment of the present invention includes a bracket 301 projecting laterally outward from the reaping portion main body (the mowing frame 25), and a laterally outward or lateral direction on the bracket 301. The motor 351 is fixed to the pedestal 340 of the support member, and the urging member 360 is provided integrally with the pedestal 340.

  Thereby, the motor 351 and the urging member 360 of the operating device can be provided compactly between the cutting unit main body (the cutting frame 25) and the front side divider 110. In addition, as a result, it is possible to prevent the cereals and the like from being caught in the operating device when the combine 200 is traveling.

  Furthermore, according to the combine 1 which concerns on one Embodiment of this invention, and the combine 200 which concerns on other embodiment, it is consistent between the rear side divider 120 and the front side divider 110 in the horizontal one side part of the said traveling body. Therefore, it can be provided so that no gap is generated. Therefore, when the position of the front side divider 110 is changed to the storage position by contact with a cocoon or the like, or when the front side divider 110 is changed to the working position by moving away from the cocoon or the like, the uncut cereal cocoon at the heel side is transferred to the cutting unit 20 It is possible to prevent the vehicle from being caught or being stepped on at the traveling unit provided in the traveling vehicle body in the previous period.
