摘要：
The utility model relates to agricultural engineering, in particular to seeders for sowing grain crops. A combined sowing unit includes a frame with a towing device, a hopper with sowing devices, support wheels, coulters and a roller. The coulters contain a stand, to the base of which a lancet paw is fixed, and a seven-duct. The seed pipe is made in the form of a hollow pipe and at the bottom is equipped with a U-shaped bracket, the ends of which are directed in the direction opposite to the direction of movement of the coulter. The seven-conduit is installed with the possibility of vertical movement along the rack, and in cross-section the seven-conduit has the shape of a circle. Behind the coulters, a roller attachment is installed containing an H-shaped frame and rods, a nut and a spring, and rollers of the loosening and leveling type are installed on each rod. The cultivating roller contains an axle and disk cultivators. Disc rippers are mounted on the axis of the ripper type roller at equal intervals in the horizontal plane, and triangular recesses are made along the periphery of the disc rippers. 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, 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. The mounted knives along the longitudinal axis of symmetry of the implement for rolling soil form an angle, the apex of which is directed towards the rotation of the leveling roller. On the outer surface of the knives there are triangular-shaped recesses, the tops of which are sharpened bilaterally. Such a design of the combined sowing unit will improve the quality of sowing of grain crops.Полезная модель относится к сельскохозяйств
