[0002]

Heretofore, in this type of combine, there has been already known a combine in which a mowing part is slidably moved in the horizontal direction. The purpose of moving the mowing part laterally is to move the mowing part to the left as much as possible (uncut ground side) when turning around with the uncut side left, and to move the crawler between the uncut kernel and the traveling crawler. To increase
Make sure that the mud that the crawler extrudes does not push down uncut culms, and when performing middle splitting work, set the mowing part to the left or right middle position or the right side and position the weeds in front of the right traveling crawler. The right running crawler does not step on the right uncut culm. An object of the present invention is to simplify the transmission structure to the cutting unit in such a horizontal sliding device of the cutting unit.

Shaft (70), which is rotatably connected around the shaft, and which receives the power from the cutting input shaft (73) and conveys the cereal stalk cut by the cutting blade (21) to the start end of the feed chain (5). The vertical conveying units (22) and (23) are arranged so that the distance in the left-right direction is always kept substantially the same with respect to the reaping transmission shaft (76), and are moved substantially in parallel. The present invention is further embodied as follows, that is, the above-described cereal stem raising member (18) and the reaping mechanism can be easily simplified. The blade (21) is connected to the traveling body (3)
Alternatively , the reaping transmission shaft (76) is configured to be slidable in the front-rear direction with respect to the longitudinal axis (70) while being configured to be slidable relative to the reaping main frame (25) in the lateral direction.
