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, a roller attachment is installed, containing a frame, grinding and pressing rollers, rods with springs. The grinding roller contains an axle and disc rippers. Disk rippers are installed on the axis of the grinding roller at regular intervals, and triangular grooves are made along the periphery of the disk rippers. The packer roller contains an axle, side and intermediate discs. Side and intermediate discs are mounted on the horizontal axis at regular intervals in the horizontal plane. V-shaped loosening elements are installed along the circumference of the lateral and intermediate disks of the compacting roller with an equal angular pitch. Such a design of the combined sowing unit will improve the qualit
