摘要：
The utility model relates to agricultural engineering. The combined seeding 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. Along the longitudinal axis of symmetry of the lancet paw, a knife is installed in front of it in front of the rack, the front edge of which is sharpened. 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 seed tube and is rigidly fixed with the lower part of the plate in the form of an isosceles triangle and the inner sides of the duckfoot wings, with the concave side of the leveler facing towards the direction of the opener movement, and the lower part of the leveler deflected in the direction opposite to the direction of movement of the opener. A roller attachment is installed behind the openers, which contains an axle, side discs, sealing plates and knives. The sealing plates are rigidly fixed to the outer surface of the side discs. The knives are rigidly fixed to the sealing plates and the roller head axle. The knives, fixed on the axle of the roller attachment, are located between the knives fixed on the slats. The utility model improves the quality of sowing grain crops. 7 ill.Полезная модель относится к сельскохозяйственному машиностроению. Комбинированный посевной агрегат включает раму с прицепным уст
