DEVICE FOR GRAIN MATERIALS SPREADING Russian patent published in 2010 - IPC B02C4/10 B02C15/04 

FIELD: agriculture.

SUBSTANCE: invention is intended for usage in the agroindustrial complex of grain processing and food industries. The device for grain materials spreading contains a lower concave working surface and a curvilinear working surface, their roughness and curvature adjustable; the curvilinear working surface is positioned over the lower working surface (with a gap between them) and is induced to oscillate relative a stationary suspension axle in an adjustable kinematic swinging mode. The lower concave working surface is stationary; the upper curvilinear working surface is cylindrical in shape and is arranged so that to enable its rotation round its axis when coming in contact with grains in the direction contrary to that of the oscillatory motion. The gap between the working surfaces is designed to be adjustable. The device is equipped with a bilateral nipple enveloping the cylindrical working surface; the nipple has ducts for delivery of grains into the working zone between the working surfaces and is equipped with a fly gate switching over when in the position of maximum deviation of the cylindrical working surface and brushes for removal of the spreading products from the concave working surface that are attached on the outside of the bilateral nipple ducts.

EFFECT: provision for efficient formation of grain materials spreading products.
