In the known threshing machine sorting apparatus, when the threshing sorting process is continued and a foreign matter such as straw waste is caught between the fins, the proper opening of the fin is determined. Therefore, the sorting performance could not be made appropriate. Further, since the tension of the spring changes between when the fin is opened and when the fin is closed, the fixing force is different, and it is difficult to select the inertia force due to the swing of the fin and the strength of the spring.

[Action] Threshing material generated in the handling room and leaked from the receiving net,
After being sorted in the rough sorting section composed of fins, the process proceeds to the most leak sorting section and undergoes sieve sorting and air sorting, and the sorts remaining on the rough sorting section and the most leak sorting section are two or more. The process proceeds to the downflow screening section, where the air is screened while being further screened. When adjusting the leakage performance by changing the inclination angle of the fins according to sorting conditions such as the amount (layer thickness), kind, or moisture content of the object to be treated, turning the ring body to one side causes an operation. One end of the wire pulls a portion of the swinging member that is separated from the center of rotation to one side to tilt the fin to one side, and when the ring is turned to the other side, the other end of the operation wire turns the swinging member to the side. The fin is tilted to the other side by pulling a portion separated from the moving center to the other side. In other words, when the leakage gap of the fin is widened or narrowed, the operation wire is tilted by forcible pulling, so even when foreign matter enters between the fins, the abnormality of the fin opening is understood, and The fins can be inspected in a timely manner, and the oscillating members that tilt the fins at both ends of the operation wire are held on both sides of the center of rotation. Sorting can be performed. Also, the load on the motor becomes almost constant.
