摘要：
The utility model relates to agricultural machinery, in particular to seeders for sowing grain crops. The combined sowing unit includes a frame with a towing device, a hopper with sowing devices, support wheels, coulters and a roller. The coulters contain a stand, to the base of which a lancet paw is fixed, and a seven-duct. The seed pipe is made in the form of a hollow pipe and at the bottom is equipped with a U-shaped bracket, the ends of which are directed in the direction opposite to the direction of movement of the coulter. The seven-conduit is installed with the possibility of vertical movement along the rack, and in cross-section the seven-conduit has the shape of a circle. Behind the coulters, a roller attachment is installed, containing a frame, grinding and rolling rollers, rods with springs. The grinding roller contains an axle and disk rippers. Disc rippers are mounted on the axis of the grinding roller at regular intervals, and figured recesses are made along the periphery of the disc rippers. The vertices located between the figured recesses are made triangular and directed in different directions from the geometric axis of rotation of the disk cultivators. The packer roller contains an axis, side discs. A hollow cylinder is mounted on the side discs. On the outer surface of the hollow cylinder, at equal intervals, annular sealing elements are installed, in cross section having the shape of an equilateral triangle. Pointed cultivators are installed diametrically between the annular sealing elements on the outer surface of the hollow cylinder. Such a design of the combined sowing unit will improve the quality of sowing of grain crops.Полезная модель относится к сельскохозяйственному машиностроению, в частности к сеялкам для посева зерновых культур.Комбинированный посевной агрегат включает раму с прицепным устройством, бункер с высевающими аппаратами, опорные колеса, сошники и каток.
