FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural engineering and can be used in development of devices for post-harvest treatment of selection seeds of cereals and leguminous crops, as well as grass seeds and onion black cherry. Threshing-separating device includes loading hopper, threshing chamber, unloading chamber, pneumatic separating channel, sedimentation chamber, fan, trays for collecting separated fractions, osteo separator, device for purification of exhaust air. In the pneumatic separating channel, divided into a cleaning and sorting section, an inclined supporting grid is placed. Sedimentation chamber is divided into sections of isolated impurities and sorted seeds.
EFFECT: use of the claimed invention will improve the productivity and efficiency of post-harvest processing of the selection material.
