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 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, rods with springs are rigidly fixed to the rear of the frame. Under the L-shaped brackets, a U-shaped frame is installed. The packer roller contains a single horizontal axis, side and intermediate discs mounted on the axis at equal intervals in the horizontal plane. Riping elements are installed on the lateral and intermediate disks with equal angular pitch, having the cross section in the form of an equilateral triangle, the ripping elements are rigidly fixed along the periphery of the lateral and intermediate disks, and the sharp vertices of the ripping elements are directed in different directions from the geometric axis of rotation of the packer roller. Improving the quality of sowing crops. 7 ill.Полезная модель относится к сельскохозяйственному машиностроению, в частности к сеялкам для посева зерновых культур.
