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 towing device, a hopper with sowing devices, support wheels, coulters. Each coulter contains a stand, paw and piping. A knife-shaped stand is installed along the axis of symmetry of the paws, the front face of which is bilaterally pointed and pointed with the tip towards the movement of the opener. The rack is installed at the top of the knife-shaped rack. The piping is installed between the wings of the paw behind the knife-shaped stand. The outlet of the piping is directed into the sublap space of the paw. Soil wings are installed behind the pipelines. On the back of the rack there is a bracket, a rod with a spring and a seed tube. The seed tube is installed in the bracket with the ability to change the position in height relative to the cutting edges of the wings of the legs and pressure on the soil. A wedge-shaped tip is rigidly mounted from the lower part of the vas deferens and the tip is directed towards the opener movement, and the outlet openings of the vas deferens and pipelines are located at a distance equal to the required difference in the depth of seeding of fertilizers. Behind the coulters, a roller attachment is installed, containing an axis, side disks, outer and inner drums made of rods. The outer drum is formed by rods arranged with equal angular pitch 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 geometrical axis of rotation of the roller attachment. 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 высев
