2. Description of the Related Art Since conventional dust control valves are provided in a line in the axial direction of the handling cylinder, the dust control valve itself must be formed into a long size and its adjusting operation must be performed in order to effectively perform the dust feeding action. It was necessary to set a large range. For this reason, not only the load applied to the dust control valve becomes large, causing deformation and damage, but also the operation force for adjustment and the holding force for holding the position after the operation are more than expected.

[0003]

As described above, since the conventional dust control valves are provided in a line in the axial direction of the handle cylinder, the valve itself is made long and the operation range of the adjustment is widened to effect the dust transfer action. However, since the load applied to the valve becomes large and deformation and damage are caused by this, and a considerably large force is required for the operation force for adjustment and the holding force after operation, the present invention is Provided is a dust control valve capable of solving the conventional problems, reducing the load on each dust control valve, preventing deformation and damage of the valve itself, and more effectively performing the dust feeding action. It was created for the purpose of.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention is directed to adjusting the number of dust particles in the inner wall of the handling chamber around the upper portion of the handling barrel at intervals in the axial direction of the handling barrel. In the case where the valves are arranged in a row, the dust control valves that can be arranged in a row are provided in a plurality of rows, and all the dust control valves are interlockingly connected to change and adjust the inclination angle. .

[0005]

With this structure, the tip end side of the grain culm traversed in the handling chamber from the supply side to the culm side is threshed by the rotation of the handling barrel, and the straw culms after threshing are the culm side. Is discharged to the outside of the machine from the handling room and is sorted by wind.
Then, the slanting angle of the dust control valve is changed according to the state of the threshing process in the handling room to adjust the residence time of the threshing process which is swung by the handling teeth in the handling chamber to improve the processing. However, in that case, all the dust control valves that are lined up in multiple rows change the tilt angle in conjunction with each other, and the dust control valves are lined up in the claw through which the handling teeth pass ahead of the upper part of the handle cylinder. The grain removal guided by the dust transfer control valve is succeeded by the trailing handle teeth but is inherited by the dust control valves arranged in rows and similarly guided, and the residence time in the handle chamber is adjusted.
