摘要：
The utility model relates to agricultural engineering, 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 an H-shaped frame and rods, a nut and a spring, and rollers of the loosening and leveling type 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 axle, side discs and a hollow cylinder. Rippers are installed on the outer surface of the hollow cylinder. Rippers are mounted on the surface of the hollow cylinder along helical lines, the direction of which begins from the longitudinal axis of symmetry of the roller attachment and is directed towards the side disks of the hollow cylinder. In the cross section, the rippers have a diamond shape and with sharp edges are directed towards the movement of the leveling roller, and the tops of the rippers are sharpened and directed in different directions from the geometric axis of rotation of the leveling roller.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 агр
