Claims (1)

[Claims for Utility Model Registration] The swinging frame 8 is provided with a grain pan B for specific gravity sorting and a grain sieve 6 for filtering and sorting the grains subjected to specific gravity sorting therein, as well as a mechanism capable of changing the filtration rate of the grain sieve 6. In the oscillating sorting device of a combine threshing machine, the vehicle speed sensor 2
A control circuit 21 is provided that automatically controls the operation of the filtration rate changing mechanism so that the filtration rate is high when the gearbox is in a high speed or high speed operation state based on a detection signal from a device that detects a zero or speed change operation state. A oscillating sorting device on a combine threshing machine. The filtration rate changing mechanism changes the filtration and sorting member 14, which has a smaller mesh size than the grain sieve 6, to the grain sieve 6.
A swing sorting device for a combine threshing machine according to claim 1, which is configured to be moved into and out of a lower position. The oscillating sorting device for a combine threshing machine according to claim 1, wherein the filtration sorting member 14 is composed of a plurality of types having different filtration meshes.
