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 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 installed 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 spaced from each other 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 H-shaped frame and rods, a nut and a spring, and rollers of the cultivating and leveling type are installed on each rod. The cultivating roller contains an axle and disk cultivators. The leveling roller contains an axis, side and intermediate disks mounted on the axis at regular intervals in the horizontal plane. Knives are installed around the circumference of the side and intermediate discs with equal angular pitch, with one side of the knives mounted on the intermediate disc, and the other side of the knives mounted on the side disc with a deviation to the side opposite to the direction of rotation of the leveling roller. On the outer surface of the knives, triangular-shaped recesses are made, the tops of which are sharpened bilaterally. Such a design of the combined sowing unit will improv
