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 are mounted rollers of the cultivating and leveling type, containing a frame and rods with springs. The cultivating roller contains an axle, end and intermediate disks. On the periphery of the end and intermediate discs, trims are installed. The leveling roller contains an axis, end and intermediate disks. At the periphery of the end and intermediate disks, rods are installed, and the rods in the cross section have the shape of a polyhedron, and the geometrical axes of rotation of the rollers are parallel to each other and perpendicular to the direction of motion of the combined sowing unit, and the bars and rods are parallel to the geometrical axes of rotation of the rollers.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 р
