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 hitch, a hopper with seeding devices, support wheels, openers. Each opener includes a tine, a duckfoot share, a seed tube. The stand is made hollow and is installed along the longitudinal axis of symmetry of the duckfoot paw. On the continuation of the vertical axis of symmetry of the rack and coaxially to the rack, a tetrahedron-shaped soil deepener is installed and its sharp edge is directed towards the direction of the opener movement. An outlet hole is made in the lower part of the soil deepener and is directed in the direction opposite to the direction of movement of the opener, and the outlet openings of the seed pipe and the soil deepener are located from each other at a distance equal to the required difference in the depth of planting seeds and fertilizers. A C-shaped leveler is installed under the vas deferens and is rigidly fixed to the lower part of the plate in the form of an isosceles triangle and the inner sides of the duckfoot wings. A press roller is installed behind the openers. L-shaped brackets with guide bushings are rigidly fixed to the rear part of the frame. Rods with springs are installed in the guide bushings. A U-shaped frame is installed under the L-shaped brackets. The packer roller is installed in a U-shaped frame. The press roller contains an axle, side discs, sealing plates and knives, the sealing plates are rigidly fixed on the outer surface of the side discs, the knives are rigidly fixed on the sealing plates and the press roller axis, and the knives fixed on the press roller axis are located between the knives fixed on the strips .This design of the combined sowing unit will improve the quality of sowing grain crops.Полезная модель относится к сельскохозяйственному машиностроению, в частности, к сеялкам для посева зерновых культур.Комбинированный посевной агрегат включает раму с п
