FIELD: agriculture.
SUBSTANCE: present group of inventions can be used for separating grain mass from heads. The heads are fed into a threshing gag, formed by inner and outer threshing-separating parts. Threshing and separation of grains takes place in the threshing gap in the field of centrifugal forces. The grains are collected by cells on the flexible meshy surface of the outer threshing-separating part. The grains are transported in these cells to the reverse curve section, where they are separated. Components without grains are removed from the meshy surface by a suction air stream on the section with constant centripetal acceleration of the meshy surface using a convergent tube, connected to a suction air pipe.
EFFECT: reduced damage to grains.
