[Prior Art]

 Conventionally, several dust control valves were provided around the handling cylinder at intervals from the grain culm supply side to the culm side of the handling chamber, and these dust control valves were linked and linked in the axial direction of the handling cylinder. It is a generally known configuration to change and adjust the inclination angle, but when threshing a wet material, the threshing grains in the handling chamber become lumps and are scattered around by the handling teeth, and the lumped threshing grains are crushed. The dust control valve was operated to the “open” side so that the dust control valve was forced to the culm side when an impact sound was generated due to the impact on the handle cylinder cover. However, at this time, the agglomerate also impacts the dust control valve and gives an excessive impact force, which may deform or damage the dust control valve, which often occurs and must be corrected or replaced. Is.

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides several dust control valves around the handling cylinder at intervals from the grain culm supply side to the culm side of the handling chamber. In a type in which valves are connected in series to change and adjust the tilt angle with respect to the axis of the handle cylinder, the dust control valves are connected by inserting an ammunition machine and individually turned and returned by an excessive impact force. It was structured.

[0005]

[Action]

 With this configuration, the tip side, which is horizontally fed from the grain culm supply side toward the culm side, is threshed by the rotation of the handling cylinder, and the straw culms after threshing are located outside the culm side. Those that are discharged to the shroud and fall from the handling room due to threshing are sorted by wind. Then, the dust control valve is operated according to the state of the threshing treatment in the handling room to adjust the residence time of the threshing that is swung by the rotation of the handling teeth in the handling room to improve the treatment, but When threshing the wet material, the threshing becomes a lump and vigorously moves inside the handling chamber and impacts the dust control valve. Then, since each dust control valve is connected by inserting an ammunition, it changes its direction due to its impact force and returns instantly to alleviate the impact force and perform the original dust action.
