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 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 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, there is a soil deepener in the form of a tetrahedron and with a sharp edge directed towards the direction of movement of the opener. 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 tube 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 the direction of the opener movement, and the lower part of the leveler deflected in the opposite direction to the opener movement. A roller attachment is installed behind the openers, which contains an axle, side discs, outer and inner drums made of rods. The outer drum is formed by rods located with equal angular pitch along the periphery of the outer surface of the side discs. The inner drum is formed by rods rigidly fixed to the inner sides of the side discs, and the rods of the outer and inner drums are parallel to the geometric axis of rotation of the roller attachment. Such a 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
