VIBRATION MACHINE FOR SEED PRESOWING TREATMENT Russian patent published in 2016 - IPC A01C1/00 

FIELD: agriculture; machine building.

SUBSTANCE: vibration machine for seed pre-sowing treatment comprises grinding drum, which inner surface is coated with rubber, with discharge hole, working member, dispensing bin, and discharge chute arranged elastically on base. Grinding drum is made conical, multithread, screw and is made up of guide elements made of three and more twisted along screw line in longitudinal direction relative to longitudinal axis and bent in helical line in transverse direction on mandrel in form of paraboloid of revolution made with side edges of convex curvilinear shape, with laps and circumscribed by curves varying in order and degree of curvature. At that, along whole length inside grinding drum overlap are formed in form of helical blades, wherein along whole length of grinding drum helical spring is arranged with flat section of turns and with device to vary turn pitch by spring compression or expansion.

EFFECT: simplified design of device allows to expand its functional capabilities.
