摘要：
The utility model relates to agricultural engineering, 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 coulter, and the outlet holes 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, a hollow drum and rippers. The rippers are mounted on the surface of the hollow drum along helical lines, the direction of which begins from the longitudinal axis of symmetry of the hollow drum and is directed to the end sides of the hollow drum, and in the cross section, the rippers have a circle shape.Полезная модель относится к сельскохозяйственному машиностроению, в частности к сеялкам для посева зерновых культур.Комбинирован
