FIELD: agricultural engineering.
SUBSTANCE: machine for pre-sowing seed treatment is proposed, containing a grinding drum, loading and unloading trunnions, the inner surface of which is covered with a layer of rubber, and tension spring equipped with a device for changing the pitch of turns is mounted along the entire length of the machine. Grinding drum is assembled from sections, the lateral surface of which is made of two rectangles and two parallelograms, connected in pairs by their lateral sides to each other, forming a square at the ends of the sections, while the square of each subsequent section is rotated relative to the previous one by an angle of 180°. Grinding drum is placed on bed by means of frame with pneumatic bellows inserted into the device.
EFFECT: invention provides high quality of obtained seeds.
