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, there is a roller set-top box containing an axis, side discs, sealing plates and knives. The sealing plates are rigidly fixed on the outer surface of the side discs. The knives are rigidly fixed on the sealing plates and the axis of the roller consoles. The knives, fixed on the axis of the roller set-top box, are located between the knives mounted on the slats. Such a design of the combined sowing unit will improve the quality of sowing grain 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.
