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, seed tube. On the longitudinal axis of symmetry of the lancet paw in its front part in front of the rack is a knife, 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, rods with springs are rigidly fixed to the rear of the frame. Under the L-shaped brackets, a U-shaped frame with a packer roller is installed. The rods at one end are pivotally mounted on the longitudinal beams of the U-shaped frame, the other in the guide bushings. The packer roller contains an axle, side discs and cultivators. Rippers are rigidly fixed around the periphery of the side discs with equal angular pitch. Triangular notches are made on the outer surface of the cultivators, the vertices of which are directed in different directions from the geometric axis of rotation of the packer roller.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 раму с прицепным устройством, бунке
