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

FIELD: agriculture; engineering.

SUBSTANCE: machine for grinding seeds contains grinding drum unloading window, working body, hopper, the unloading tray inside the container mounted coil spring equipped with a device for changing the pitch of turns by stretching or compressing it. This grinding drum is made in the form of the container is elastically mounted on the base with the vibrator and is mounted on at least one strip folded along straight lines, disposed at an angle to the strip edges. Wherein the strip is rolled into a cylindrical form with coils on the outer and inner surfaces of helical lines, and curved helical surfaces with centers of curvature located inside the cross section of the container in a pocket inner surface of a semicircular shape and covered with a rubber layer internally. Inside the container is rigidly mounted conical spring with a circular cross-section turns and windings direction opposite to the direction of helical surfaces and the helical lines of the container.

EFFECT: present invention increases productivity and technological capabilities.
