摘要：
The utility model relates to agricultural engineering, in particular to seed drills for sowing grain crops.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 movement of the opener, and the lower part of the leveler deflected in the direction opposite to the direction of movement of the opener. Behind the openers, rollers are installed containing a frame, a bar with a spring, axles, end and intermediate discs. Along the periphery of the end and intermediate disks with equal angular pitch, strips and rods are installed, and the geometric axes of rotation of the rollers are parallel to each other and perpendicular to the direction of movement of the combined seeding unit, and the rollers are installed with the ability to copy the relief of the field surface and regulate the pressure on the soil surface.Su
