摘要：
The utility model relates to agricultural engineering, in particular to seed drills for sowing grain crops.The combined seeding unit includes a frame with a hitch, a hopper with seeding devices, support wheels, openers. Each opener includes a tine, a duckfoot share, a seed tube. The stand is made hollow and is installed along the longitudinal axis of symmetry of the duckfoot paw. On the continuation of the vertical axis of symmetry of the rack and coaxially with the rack, a tetrahedron-shaped soil deepener is installed and its sharp edge is directed towards the direction of the opener movement. An outlet hole is made in the lower part of the soil deepener and is directed in the direction opposite to the direction of movement of the opener, and the outlet openings of the seed pipe and the soil deepener are located from each other at a distance equal to the required difference in the depth of planting seeds and fertilizers. A C-shaped leveler is installed under the vas deferens and is rigidly fixed to the lower part of the plate in the form of an isosceles triangle and the inner sides of the duckfoot wings. A roller is installed behind the openers. L-shaped brackets with guide bushings, rods with springs, U-shaped frame are rigidly fixed to the rear part of the frame. The packer roller is installed in a U-shaped frame. The rods are hinged at one end on the longitudinal beams of the U-shaped frame, and at the other in the guide bushings. The packer roller contains an axle, side discs, sealing plates and one-sided sharpened knives.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.
