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 towing device, 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 with 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 a single horizontal axis, side and intermediate discs mounted on the axis at regular intervals in the horizontal plane. On the lateral and intermediate discs with equal angular pitch, loosening elements are installed, in cross-section having the shape of an equilateral triangle, and the sharp tops of the loosening elements are directed in different directions from the geometric axis of rotation of the roller attachment. Such a design of the com
