- the base plate 413 is supported by the support plate 411 and the support arm 412 so as to be swingable about the swing axis, with the bolts 441 as swing axes. Further, the base plate 413 is constantly biased toward the support plate 411 by the compression spring 447. For this reason, the rear side portion of the base plate 413 is brought into pressure contact with the other side plate surface of the support plate 411, and a drag force due to friction is generated. As a result, the base plate 413 can maintain its swing angle and can be arbitrarily adjusted within the longitudinal width of the adjustment long hole 411b by applying an external force that is greater than the drag caused by friction. It has become.
- each bearing member 414e of the screw unit 414 is disposed on the left side of the base plate 413 so as to be overlapped on the left and right.

- the turning power of the drive motor 415 is transmitted to the screw shaft 414a of the screw unit 414 via the connecting shaft 415c, and the screw shaft 414a can be rotated. Then, when the screw shaft 414a is rotated by the drive motor 415, the position of the moving nut 414c is arbitrarily changed within the movable range on the screw shaft 414a.
- the moving nut 414c Since the guide roller 416 is in contact with the guide 413j, the moving nut 414c does not rotate around the screw shaft 414a even when an external force in the vertical direction is applied to the arm 421 or the weed ridge 43. Further, since the guide roller 416 rolls on the upper guide 413j of the pair of upper and lower guides 413j and 413j, the friction resistance is small. That is, the moving nut 414c can move the arm 421 stably.

It is said. Then, when the other end of the support rod 42 is moved in the front-rear direction by the position adjusting device 41, the support rod 42 moves in the front-rear direction and swings in the front-rear direction.
- the collar 43 moves in the left-right direction.
- the drive motor 415 is driven from the control unit 8 to move the moving nut 414c from the front side to the rear side of the screw unit 414.
- the support rod 42 is swung clockwise around the support shaft 422b by moving the front end rearward (see the black arrow in FIG. 9). That is, the rear end of the support rod 42 is moved to a position away from the pulling longitudinal transmission pipe 306 by the position adjusting device 41.
- the front weed bush 431 is moved to a position where the rear end of the support rod 42 is separated from the longitudinal vertical transmission pipe 306, so that one side end (front end) pivotally supported so as to be horizontally rotatable is used as a swing center. It is swung clockwise. That is, the rear end of the front weed fence 431 is moved by the position adjusting device 41 to a position away from the pulling vertical transmission pipe 306. With the movement of the rear end of the front weed fence 431, one side end (front end) of the rear weed fence 432 is moved to a position away from the pulling vertical transmission pipe 306. At the same time, the other side end (front end) of the rear weed basket 432 is moved toward the front side on the weed weed guide 432d. Accordingly, the left and right positions of the weed ridges 43 supported by the support ridges 42 are at positions that are separated from the pulling longitudinal transmission pipe 306, that is, at positions that are separated from the cutting unit 3 and the body frame 9 (airframe).

- the horizontal position of the weed ridge 43 can be arbitrarily adjusted by the position adjusting device 41. Specifically, the left and right positions of the weed culvert 43 can be changed to the retracted position during the non-cutting operation, and to the extended position that provides an arbitrary overhanging amount during the cutting operation.
- the lateral movement amount of the rear end of the support rod 42 with respect to the longitudinal movement amount of the front end of the support rod 42 is substantially proportional to the 1/2 power of the support rod length L that is the swing radius of the support rod 42. . Therefore, by configuring the support rod length L to be sufficiently large, the lateral movement amount of the rear end of the support rod 42 can be made larger than the longitudinal movement amount of the front end of the support rod 42.
- the support rod 42 is installed along the cutting unit 3 and the machine body so that the longitudinal direction is rather the left-right direction of the machine body rather than the left-right direction. Therefore, even when the support rod length L is sufficiently large, the installation width of the support rod 42 in the left-right direction can be suppressed. Thereby, it is not necessary to provide the installation space in the left-right inward direction of the machine body frame 9 without increasing the size of the position adjusting device 41, and a sufficient amount of lateral movement of the weed culvert 43 can be secured.

- the amount of movement can be increased.
- the left and right position of the weed rod 43 can be changed by the swinging of the support rod 42 in the left-right direction. As a result, the left and right position of the weed pod 43 can be changed without changing the vertical position of the weed pod 43.
- the position adjusting device 41 is configured such that the other side end of the support rod 42 can be moved to an arbitrary front-rear position by a drive motor 415 that is an actuator.
- the position adjusting device 41 is simplified, and the operator of the combine 1 can remotely control the position of the support rod 42 by this position adjusting device 41. It can be adjusted easily. As a result, it is not necessary to increase the size of the position adjusting device 41, and it is not necessary to provide an installation space in the left-right inward direction of the machine body frame 9, and the amount of movement in the left-right direction of the weed culvert 43 can be ensured.
