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. Along the longitudinal axis of symmetry of the lancet paw, a knife is installed in front of it in front of the rack, the front edge of which is sharpened. 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 press roller is installed behind the openers. L-shaped brackets with guide bushings are rigidly fixed to the rear part of the frame. Rods with springs are installed in the guide bushings. A U-shaped frame is installed under the L-shaped brackets. The packer roller is installed in a U-shaped frame. The rods at one end are pivotally mounted on the longitudinal beams of the U-shaped frame, with the other in the guide bushings, with the possibility of vertical movement of the rods in the guide bushings. The press roller contains an axle, side and intermediate discs, and rods. This 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.
