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. Each opener includes a stand, lancet paw, seed tube. On the longitudinal axis of symmetry of the lancet paw, a knife is installed in front of the rack in front of the rack, the front edge of which is pointed. The stand is hollow and mounted along the longitudinal axis of symmetry of the lancet paw. On the continuation of the vertical axis of symmetry of the rack and coaxially to the rack, a subsoiler in the form of a tetrahedron is installed and the sharp edge is directed towards the direction of movement of the opener. An outlet is made in the lower part of the subsoiler and is directed to the side opposite to the direction of movement of the coulter, and the outlet openings of the vas deferens and the subsoiler are located at a distance equal to the required difference in the depth of seed and fertilizer placement. Behind the coulters, a roller attachment is installed containing successively mounted rollers of the loosening and leveling type, an H-shaped frame, brackets, rods, nuts and springs. The cultivating roller contains an axle and disk cultivators. The leveling roller contains an axle, side and intermediate disks, and rippers. The rippers in the cross section are square and twisted along the entire length by an angle α relative to their longitudinal axis of symmetry so that the sharp edges of each ripper form helical lines, and the sharp edges of the rippers are directed in different directions from the geometric axis of rotation of the leveling roller. sowing unit will improve the quality of sowing 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, с
