MACHINE FOR PRESOWING TREATMENT OF SEEDING MATERIAL Russian patent published in 2014 - IPC A01C1/00 B02B3/00 

FIELD: agriculture.

SUBSTANCE: machine for presowing treatment of seeding material comprises a working element, a glazing drum which inner surface is coated with a layer of rubber, with a discharge window, a drive mechanism, a measuring hopper, a discharge chute. The working element is made of unjointed rods-rollers. The rods-rollers are made in the form of a spiral tetrahedral column coated with rubber layer, and are provided on both sides with the trunnions. The trunnions are able to roll on the feelers mounted inside the glazing drum. At that the diameter of the trunnions is greater than the maximum diameter of the rods-rollers and provides a constant gap between them and the walls of the glazing drum. The said gap is larger than the maximum size of the seeds.

EFFECT: machine has simplified construction, increased productivity and enhanced technological capabilities.
