摘要：
A useful model refers to agricultural machinery, in particular to seeders for sowing cereals.Combined seeding unit includes a frame with a trailing device, a hopper with sowing devices, support wheels, openers. The coulters contain a stand, lancet paw, and the seminal duct. On the axis of symmetry of the lancet paw there is a knife-like stance, the front edge of which is pointed. Between the wings of the pointed paw, parallel to the cutting edges of the wings of the pointed paw, is a plate in the shape of an isosceles triangle. A horizontal groove is made at the base of the plate. The seminal duct is installed vertically along the axis of symmetry of the lancet paw above the horizontal groove of the plate, and a vertical groove is made from the back of the lower part of the vas deferens. The coulters are equipped with a roller attachment containing a frame, grinding and packing rollers, bars with springs. The grinding wheel contains an axis and disc rippers. Disc rippers are installed on the axis of the crushing rink at regular intervals, and on the periphery of the disc rippers, figured grooves are made. The vertices, located between the figured notches, are triangular and directed in different directions from the geometrical axis of rotation of the disc rippers. The rolling roller contains an axle, side discs. On the side discs a hollow cylinder is installed. On the outer surface of the hollow cylinder, at regular intervals, annular sealing elements are installed, in the cross section, having the shape of an equilateral triangle. On the outer surface of the hollow cylinder, sharpened rippers are installed diametrically between the annular sealing elements. They are triangular and directed in different directions from the geometrical axis of rotation of the disc rippers. The rolling roller contains an axle, side discs. On the side discs a hollow cylinder is installed. On the outer surface of the hollow cylinder, at regular intervals, annular sealing elements are in
