MULTI-SHELF DEVICE FOR VIBRATION TRANSFER OF GRAIN MATERIALS Russian patent published in 2010 - IPC B65G27/20 B65G27/32 

FIELD: mechanics.

SUBSTANCE: proposed device comprises a frame, tie rods, con rods, drive and trays (1). Posts (5) integrate trays into two sections, and trays of one section are arranged between trays of the other section. Both sections on posts with guides (6) are mounted on framer (7) and jointed with pins 12 via articulated system made up of tie rods (15), slide (14) and con rod (13), said pins being fixed off-center on a pair of disks (11) drive by engine (10). Tray sections reciprocate in horizontal plane asymmetrically due to conversion of engine rotation by articulated system. Device efficiency varies from zero to maximum with dimensionless parametre K=(r-c)/b increasing from zero to unity and reduces to zero with said parametre increasing to amount allowed by articulation diagram, where r is con rod length, c is the distance between disk center and tie attachment to trays, and b is eccentricity of pin attachment to disk.

EFFECT: simplified design and higher efficiency.
