Conventionally, Japanese Utility Model Laid-Open No. 1-12
As disclosed in Japanese Patent No. 7427, there is a technique for connecting both ends of a plurality of chaff sheave fins to left and right fin mounting plates. It is easy for threshing dust and straw chips to enter between the end or the fin mounting plate and the side wall of the swinging sorter and bite, and the inclination angle of the chaff sheave fin for changing the grain leakage interval is improperly adjusted or malfunctions. There is a problem. In addition, Japanese Utility Model Application 5-113939
As shown in the publication, the end of the chaff sieve fin is joined and connected to the side wall of the rocking sorter, thereby preventing threshing dust and straw chips from being caught between the end of the chaff sieve fin and the side wall of the rocker sorter. It is not easy to simplify the work of attaching and removing the fins, and it is necessary to provide the chaff sheave fin support strength to the side wall of the rocking sorter. This facilitates the simplification of the chaff sheave fin installation structure and the reduction of manufacturing costs. There is a problem that it cannot be obtained.
