FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building, particularly, to devices for accurate sowing of tilled crop seeds. Device for seed sowing of seeds is made in form of a set of fixed and two movable disks. Discs are made with possibility of displacement around horizontal axis by specified angle and their fixation. On cylindrical surfaces of fixed cylindrical disc, movable inner cylindrical disc and movable outer cylindrical disc there are cells, above which there are annular trapezoidal grooves. On the end surface of the fixed cylindrical disc there are circular holes with uniform pitch along the circumference. On end surface of movable cylindrical discs there are elongated holes with uniform circumferential pitch with width equal to diameter of round holes.
EFFECT: use of the invention will make it possible to increase seed coverage of cells, uniformity of sowing with specified distances in one seat and between sockets that promotes creation of the best conditions for growth and development of plants.
