FIELD: agriculture; machine building.
SUBSTANCE: apparatus includes a conveying roll with a helical winding for moving and ejecting cobs from the threshing area, a threshing roller with projections of a curvilinear shape and a loading device. Rollers are located parallel and rotate in one direction, in the direction opposite to rest direction of projection. Projections of curvilinear shape are installed with possibility of formation of spiral helical surface on threshing roll. Rows of projections have recesses equal to thickness of projections, and alternate with them in row. Each next row of projections is installed relative to previous one with displacement along longitudinal axis of threshing roll by value equal to thickness of projection or recess.
EFFECT: invention provides increased efficiency and reduced damage of selection material.
