摘要：
The utility model relates to agricultural machinery, in particular, to seeders for sowing grain crops.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 loosening and leveling rollers, an H-shaped frame, brackets and rods. A nut and spring are installed on each rod. The cultivating roller contains an axle and disk cultivators. Disc rippers are mounted on the axis of the ripper type roller at equal intervals in the horizontal plane, and triangular recesses are made along the periphery of the disc rippers. The leveling roller contains an axis, an outer and an inner drum. The inner drum is hollow with a smooth outer surface. The outer drum is formed by side and intermediate discs and rods. The lateral disks are mounted on an axis, and the intermediate disks are mounted on the outer surface of the inner drum at regular intervals in the horizontal plane and offset from each other in the vertical plane. On the periphery of the side and intermediate disks with equal angular pitch, recesses are made. The rods are installed in the recesses in such a way that they form a multi-helix line, and in cross section the rods have the shape of a polyhedron.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 вк
