From the start end to the end. The cereal culm transported to the terminal end of the stock transport device 6 is then taken over by the starting end of the vertical transport device 8 and transported to the terminal portion, and further carried forward to the threshing device 3 behind and transported, and threshing. It will be processed. In a mowing operation in a wetland or the like, the mowing moving unit A is moved in the left and right direction with respect to the machine body by the left and right moving means 11 to prevent muddy soil from rising to the uncut grain culm side, and to prevent the grain on the ridge. The mowing work is performed while eliminating uncut culms of the culm.

So that the mowing moving part A
When the mowing moving part A moves left and right,
The amount of deviation due to the rotation between the end and the right end is substantially the same. FIG. 1 shows a combine harvester equipped with an embodiment of the present invention. A threshing device 3 is provided on the upper part of the traveling body 1 having the traveling device 2, and in front of the threshing device 3, a mowing movement formed by the weeder 4, the raising device 5, the stock transport device 6 and the cutting blade device 7. A section A and a vertical transport device 8 for transferring the grain culm transported by the stock transport device 6 which is a part of the mowing moving portion A to the rear threshing device 3 and transporting the same are arranged. At the front upper portion of the traveling machine body 1, a rear upper portion of a lifting and lowering support frame 9 for raising and lowering the mowing moving portion A and the vertical transport device 8 is attached. It is supported by means 11 (in this embodiment, a motor) so as to be movable in the lateral direction.
As shown in FIGS. 2 and 3, the mowing moving unit A is supported by a pin 12 having a center on an axis P provided on an elevating support frame 9, together with a left and right moving unit 11 so as to be freely rollable. A drive shaft 13 is connected to the left and right moving means 11, and a boss 15 fixed to the mowing moving portion A by the rotation of the drive shaft 13.
Is configured to move the guide shaft 14 to the left and right, and move the mowing moving unit A to the left and right. The left and right moving means 11 may be of an electric type or a hydraulic type. The lifting support frame 9 includes a left-right rotating means 1 for rotating the mowing moving unit A in the left-right direction with respect to the machine body moving direction.
0 (in this embodiment, a cylinder that expands and contracts by hydraulic pressure and a rod). The left-right rotation unit 10 is configured to rotate both the reaping moving unit A and the left-right moving unit 11 in the left-right tilt direction around a pin 12 concentric with the axis P. A plate 16 supporting the reaping moving part A and the left and right moving means 11 is connected to the rod 10a which extends and contracts in the substantially vertical direction from the left and right rotating means 10, and the reaping moving part A and the left and right moving means 11 are connected to each other. When the supporting plate 16 is rotated about the pin 12 by the rod 10a, the mowing moving part A and the left and right moving means 11 are configured to rotate in the left and right tilt direction. The left and right rotating means 10 may be an electric type, a hydraulic type, or the like. Further, the pin 12 may be attached to any position of the lifting support frame 9 as long as it does not affect the arrangement and movement of the left and right moving means 11, the left and right rotating means 10 and other devices. Further, the left and right rotating means 10 is also located at a position where the reaping moving part A can be rotated with respect to the pin 12 on the side around the pin 12 about the axis P, and the left and right moving means 11 and other devices. Any place that does not affect the arrangement or movement of the slab may be used. In a mowing operation in a wetland or the like, the mowing moving portion A is moved and adjusted in the left-right direction with respect to the machine body to prevent the muddy soil from rising to the side of the uncut culm and prevent the culm from being cut off at the ridge. We perform reaping work while losing. When the mowing moving unit A moves in the left-right direction, the vertical transport device 8 also moves left and right following the movement of the mowing moving unit A, and the harvested grain culm moves from the stock transport device 6 to the vertical transport device 8 and then to the vertical transport device. It is smoothly transported from the device 8 to the threshing device 3. The work is performed while rotating the mowing moving part A about the pin 12 provided on the elevating support frame 9 by the left and right rotating means 10 to the left and right with respect to the machine body traveling direction. For example, when the mowing moving unit A is adjusted to move left and right, the machine body tilts toward the moving side. Then, as compared with the case where the lower part of the mowing moving part A does not move and adjust, the lower part of the mowing moving part A frequently contacts or collides with the ground. This grounding can be prevented. This operation may be performed manually, but in conjunction with an inclination sensor (not shown) provided on the traveling machine 1 or the mowing moving unit A,
The mowing moving part A may be configured to be always kept horizontal or at a predetermined gentle inclination. However, since the ground is not always horizontal, a plurality of ultrasonic sensors or the like (not shown) are provided below the mowing section, and the rotation of the mowing moving section A is maintained so that the distance between the mowing section and the ground is always constant. The movement may be controlled. Next, FIG. 4 will be described. The position of the pin 12 about the axis P, which is a fulcrum for rotating the reaping moving section A in the left-right tilt direction with respect to the machine body traveling direction by the above-described left-right rotating means 10, is moved by the reaping movement. The arrangement is such that the mowing moving section A is moved in the left-right direction by the means 11 and is located at the center or substantially at the center of the entire stroke. As a result, when the mowing moving unit A rotates in the left-right direction, the amount of deviation due to the rotation between the left end and the right end when the mowing moving unit A moves left and right becomes substantially the same. If the left and right deviation amounts due to the rotation of the mowing moving unit A are the same, the corrected deviation amount of the rotation for preventing the mowing moving unit A from inclining right and left and the lower portion thereof comes into contact with the ground is reduced. Left and right are the same, and the amount of rotational deviation can be effectively utilized on the left and right. From the above description, it is possible to rotate the mowing moving unit A in the opposite direction even if the mowing moving unit A is tilted right and left due to the inclination or subsidence of the body to the side where the mowing moving unit A is adjusted right and left. Thus, contact and collision with the ground can be prevented. As described above, according to the present invention, the cutting and moving unit A including the weeding tool 4, the raising device 5, the stock transfer device 6 and the cutting blade device 7 is moved left and right by the left and right moving means 11. In such a configuration, it is possible to rotate left and right about the axis P with respect to the body traveling direction. Accordingly, in a wetland or the like, when the machine body is tilted to the side where the mowing moving unit A is adjusted to move left and right, the lower part of the mowing moving unit A is brought into contact with the ground by rotating the mowing moving unit A in the opposite direction. Contact and collision can be prevented. And the reaper

At the same time, the amount of deviation due to the rotation of the left end and the right end is almost the same.
You. Thus, the right and left deviation due to the rotation of the mowing moving unit A
If the amount is the same, the mowing moving part A tilts left and right
