摘要：
The utility model relates to agricultural engineering, in particular, to seed drills for sowing grain crops. The combined sowing unit includes a frame with a hitch, a bunker with sowing devices, support wheels, openers. Each coulter contains a stand, a paw and a tukovod. A knife-shaped stand is installed along the axis of symmetry of the paw, the front face of which is bilaterally pointed and pointed toward the movement of the opener. The rack is installed at the top of the knife rack. The tubing is installed between the wings of the paw behind the knife-shaped stand. The exit of the tukoprovod is directed to the subflat paw space. Rear fenders are installed behind the tukoprovod. A bracket, a spring bar and a seed tube are installed at the rear of the rack. The seed tube is installed in the bracket with the possibility of changing the position in height relative to the cutting edges of the wings of the paw and pressure on the soil. From the bottom of the seed line, a wedge-shaped tip is rigidly mounted and the tip is directed in the direction of the vomer’s movement, and the outlet holes of the seed line and the pipeline are spaced from each other at a distance equal to the required difference in the depth of embedding of seeds and fertilizers. Behind the coulters mounted rollers of loosening and leveling types, containing frame and rods with springs. The roller of loosening type contains an axis, face and intermediate disks. On the periphery of the end and intermediate discs, slats are installed. Leveling roller contains axle, end and intermediate discs. On the periphery of the end and intermediate discs, rods are installed, the rods in cross section have the shape of a polyhedron, and the geometric axes of rotation of the rollers are parallel to each other and perpendicular to the direction of movement of the combined sowing unit, and the bars and rods are parallel to the geometric axes of rotation of the rollers. will improve the quality of sowing crops.Полезная
