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. There is a packer roller 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 is mounted in a U-shaped frame. The rods at one end are pivotally mounted on the longitudinal beams of the U-shaped frame, the other in the guide bushings, with the possibility of vertical movement of the rods in the guide bushings. The packer roller contains an axis, side discs, sealing plates and knives, packing plates are rigidly fixed to the outer surface of the side discs, knives are rigidly fixed to the sealing plates and the axis of the packer roller, and the knives mounted on the axis of the packer roller are located between the knives fixed on the bars .This design of the combined sowing unit will improve the quality of sowing of grain crops.Полезная модель относится
