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. Each opener includes a stand, lancet paw, vas deferens. On the longitudinal axis of symmetry of the lancet paw, a knife is installed in front of the rack in front of it, 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 opener, 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 a frame, chopping 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 triangular recesses are made along the periphery of the disc rippers. The packer roller contains an axle, side and intermediate discs. Side and intermediate discs are mounted on the horizontal axis at regular intervals in the horizontal plane. On the circumference of the side and intermediate disks of the press roller with equal angular pitch, ripping elements are installed.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, опо
