摘要：
The utility model relates to agricultural engineering, in particular to seeders for sowing grain crops. Combined sowing unit includes a frame with a towing device, a hopper with sowing devices, support wheels, coulters. Each opener includes a stand, lancet paw, vas deferens. On the longitudinal axis of symmetry of the lancet paw, a knife is installed in front of the rack in front of the rack, the front edge of which is pointed. The stand is hollow and mounted along the longitudinal axis of symmetry of the lancet paw. On the continuation of the vertical axis of symmetry of the rack and coaxially to the rack, a subsoiler in the form of a tetrahedron is installed and the sharp edge is directed towards the direction of movement of the opener. An outlet is made in the lower part of the subsoiler and is directed to the side opposite to the direction of movement of the coulter, and the outlet openings of the vas deferens and the subsoiler are located at a distance equal to the required difference in the depth of seed and fertilizer placement. 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 are made recesses of a triangular shape, the tops of which are bilaterally sharpened. Such a design of the combined sowing unit will improve the quality of sowing of grain crops. 8 ill.Полезная модель относится к
