FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building. Vibration machine for grinding seeds is proposed, containing a grinding drum with a discharge window, a metering hopper, an unloading chute, mounted elastically on the base. Drum is made of sections, each of which is mounted from a strip, bent in one direction along straight lines placed at an angle to the edges of the strip, with alternate formation along the length of the strip of different sized equilateral and isosceles triangles. On two sides of the largest equilateral triangle there are two identical isosceles triangles with their bases, on the sides of which there are two identical equilateral triangles with two identical isosceles triangles located on their bases, on one of which there is an equilateral triangle. Sections are connected to each other with free sides of the above triangles.
