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, seed tube. 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 seeding of fertilizers. 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 and intermediate discs and cultivators, and the cultivators are rigidly fixed around the periphery of the side and intermediate discs and form an angle, the apex of which is located on the axis of symmetry of the roller attachment and is directed towards the direction of movement of the combined sowing unit. will improve the quality of sowing crops.Полезная модель относится к сельскохозяйственному машиностроению, в частности
