摘要:
The utility model relates to agricultural engineering, in particular, to seeders for sowing grain crops. The combined sowing 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 to 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 are rigidly fixed to the rear part of the frame. A U-shaped frame is installed under the L-shaped brackets. The packer roller contains a single horizontal axis, side and intermediate discs mounted on the axle at regular intervals in the horizontal plane. On the side and intermediate discs with equal angular pitch, V-shaped loosening elements are installed, and the V-shaped loosening elements are rigidly fixed by their tops along the periphery of the side and intermediate discs, and the sides of the V-shaped loosening elements are directed in different directions from the geometric axis of rotation of the press roller. Such a design of the combined sowing unit will improve the quality of sowing grain crops.Полезная модель относится к сельскохозяйственному машиностроению, в
