摘要：
The utility model relates to agricultural machinery, in particular to seeders for sowing grain crops. The combined sowing unit includes a frame with a hitch, a hopper with sowing 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 attachment is installed behind the openers, which contains a frame, chopping and rolling rollers, rods with springs. The shredding roller contains an axle and disc rippers. Disc rippers are installed on the axle of the crushing roller at regular intervals, and triangular recesses are made along the periphery of the disc rippers. The press roller contains an axle, side discs, a hollow cylinder. On the outer surface of the hollow cylinder, annular sealing elements and pointed rippers are installed at regular intervals. Such a design of the combined sowing unit will improve the quality of sowing of 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.
