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, vas deferens. 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. An ice rink is installed behind the coulters. L-shaped brackets with guide bushings are rigidly fixed to the rear of the frame. Rods with springs are installed in the guide bushings. Under the L-shaped brackets, a U-shaped frame is installed. The packer roller contains a single horizontal axis, located perpendicular to the direction of movement of the combined sowing unit, 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.Комби
