FIELD: agricultural engineering. SUBSTANCE: shake mill has carcass with sides, front and rear cross beams, brackets for connecting hangers to thresher and drive walls, lipped screen with frame mounted for transverse displacements relative to carcass, two hydraulic double-action cylinders. One of hydraulic cylinders is mounted perpendicular to side and connected with this side and frame, and other hydraulic cylinder is extending along side to connect it to thresher wall. Hydraulic cylinders are interconnected through pipelines and distribution valve and adapted to move lipped screen in transverse direction and uniformly distribute grain heap over the whole surface of screen, when grain combine operates on slopes.
