FIELD: agriculture.
SUBSTANCE: machine for grinding carrot seeds comprises a grinding drum which inner surface is coated with a layer of rubber, a hopper-metering unit, and an unloading tray. The grinding drum is formed helical around the perimeter from sections in the form of polyhedra. The latter have faces in the form of equilateral triangles interconnected with two sides on the surface of the drum and placed at an angle to one another and to its axis. At that the sections are interconnected with the free sides of the triangles. All sides of the triangles converge at one point-apex of each section to form on the outer surface of directed towards each other polygonal helical surfaces of the same pitch and broken helical lines of the same pitch. The inner surface of the grinding drum is coated with rubber layer.
EFFECT: invention has advanced technological capabilities, simplified design and improved performance.
