GRINDING MACHINE FOR SEEDS Russian patent published in 2016 - IPC A01C1/00 

FIELD: agriculture; machine building.

SUBSTANCE: machine for grinding seeds comprises grinding drum unloader window actuator, hopper, the unloading tray mounted resiliently on a base sanding drum whose inner surface is covered with a rubber layer, mounted in sections assembled from two identical sub-sections, made of an even number , at least four, identical isosceles triangles alternately connected along the perimeter of the subsection with four identical equilateral triangles forming a large end and small openings in the form of polygons. In this section two subsections connected together side of the end of apertures and the sections are attached to each other along the length of the milling drum by their small side the end of holes to form a multi-start helical grinding drum interdirected polygonal screw lines, and the working body is formed as a spring wavelike form the planar coils coated with a layer of rubber, mounted within the container and equipped with a device for changing the pitch of the turns by stretching or compressing it.

EFFECT: device allows you to expand its technological capabilities and to simplify the design.
