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 tubing is installed between the wings of the paw behind the knife-shaped stand. Rear fenders are installed behind the tukoprovod. A bracket, a spring bar and a seed tube are installed at the rear of the rack. Behind the coulters mounted skating rink. With the back of the frame rigidly fixed L-shaped brackets with guide bushings. In the guide bushings installed rod with springs. Under the L-shaped brackets installed U-shaped frame. The packer roller has a single horizontal axis located perpendicular to the direction of movement of the combined sowing unit, side and intermediate discs. The side and intermediate discs are mounted on the axis at regular intervals in the horizontal plane. On lateral and intermediate disks with equal angular pitch, loosening elements are installed, having an equilateral triangle shape in cross section, and loosening elements are rigidly fixed along the periphery of the lateral and intermediate disks, and the sharp tops of loosening elements are directed in different directions from the geometric axis of rotation of the roll-on roller. the design of the combined sowing unit will improve the quality of sowing crops.Полезная модель относится к сельскохозяйственному машиностроению, в частности к сеялкам для посева зерновых культур.Комбинированный посевной агрегат включает раму с прицепным устройством, бункер с высевающими аппаратами, опорные колеса, сошники.
