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 press roller is installed in the U-shaped frame. Bars with one end hinged on the longitudinal beams of the U-shaped frame, the other in the guide sleeves, with the possibility of vertical movement of the rods in the guide sleeves. The compactor roller contains an axle, side discs, outer and inner drums made of rods. The outer drum is formed by rods arranged with an equal angular step along the periphery of the outer surface of the side discs. The inner drum is formed by rods rigidly fixed to the inner sides of the side discs, and the rods of the outer and inner drums are parallel to the geometric axis of rotation of the roll-in roller. 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.
