るものに工夫する点にある。However, when the treated product is so wet that the grain culms harvested after early morning or after rain are targeted, the chaff plate is clogged due to adhesion of the treated product to the chaff plate, Grains were prevented from falling and the efficiency of grain recovery was likely to drop, and there was room for further improvement in terms of improving sorting performance. An object of the present invention is to effectively prevent clogging of a processed product in a chaff sheave, and to devise a structure for that purpose so that the structure can be easily modified by effectively utilizing the original structure.

材に付与するアクチュエータを設けたことにある。A feature of the present invention is that a swinging and sorting case for transporting and sorting a workpiece to be dropped and supplied from a handling chamber is provided with a large number of chaff plates inclined in the swinging direction. The chaff sheaves arranged side by side are installed, the chaff plate is attached so that the inclination angle can be freely changed, and the interlocking member that interlocks with all of the chaff plates is returned in the threshing device that interlocks with the tension operation tool for adjusting the chaff plate and the return spring. An actuator is provided to apply an impact force to the interlocking member against the spring.

ストを十分に低減できる。[Effect] In other words, since the actuator can apply an effective impact force to the chaff plate to drop the adhered matter, it is possible to reliably prevent the chaff sheave from being clogged even with a severely wet treated material, and to sufficiently improve the grain recovery efficiency. And it can definitely improve. Moreover, the structure for fixing and setting the angle of the chaff plate arbitrarily, that is, since the pulling operation tool and the return spring are combined to allow the swing of the chaff sheave, the impact force in the direction against the return spring is large. By effectively utilizing the characteristic that can be easily added, a simple modification by simply adding an actuator that acts on the interlocking member is sufficient, and the modification cost can be sufficiently reduced.
