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 an H-shaped frame, brackets and rods. Each bar has a nut, spring, rippers and leveling rollers. The ripper-type roller contains an axis and disc rippers. Disc rippers are installed on the axis of the ripper-type rink at equal intervals in the horizontal plane. The leveling roller includes an axle, side and intermediate discs, and bars. On the periphery of the lateral and intermediate discs with an equal angular step, figured grooves are made in the form of a semicircle. The lateral and intermediate discs are mounted on the axis at regular intervals in the horizontal plane and offset from each other in a vertical plane. The bars are installed in the shaped grooves in such a way that they form a multi-threaded screw line, and in the cross-section the bars have the shape of a polyhedron. The leveling roller includes an axle, side and intermediate discs, and bars. On the periphery of the lateral and intermediate discs with an equal angular step, figured grooves are made in the form of a semicircle. The lateral and intermediate discs are mounted on the axis at regular intervals in the horizontal plane and offset from each othe
