ように送塵弁の角度を設定せざるを得なかった。However, in the conventional combine described above, since only one dust valve is provided for each handling cylinder, the feeding is performed in the front half and the rear half of the handling cylinder. It was not possible to change the flow speed of the grain stick by changing the angle of the dust valve, and it was necessary to set the angle of the dust valve so that the average flow speed was obtained over the entire length of the handling cylinder.
【０００５】そのため、扱胴の前半部では、穀桿の流れ

荷が増大してしまうおそれがあった。[0005] Therefore, in the first half of the handling cylinder, the flow of the grain rod is too fast, and the loss during threshing increases. On the other hand, in the second half of the handling cylinder, the flow of the grain rod is too slow, and the handling of the handling cylinder is too slow. There is a possibility that the load of the device may increase.

The first and second handling cylinders with outer diameters are arranged at an interval in the front and rear, respectively, and the dust feed valves are individually arranged on the outer periphery of each handling cylinder so that the angle can be adjusted independently. In addition, the dust valve is constituted by a plurality of dust valve components each of which is independently adjustable in angle.
