摘要：
The utility model relates to agricultural engineering, in particular to seed drills for sowing grain crops.The combined seeding unit includes a frame with a hitch, a hopper with seeding devices, support wheels, openers. Each opener contains a rack, a lancet share, a seed pipe, a knife-shaped rack. In the seed pipe, there are parallel channels for seeds and fertilizers. The fertilizer channel is located in front of the seed channel. The lower part of the fertilizer channel is directed into the opener under the plow space, and the lower part of the seed channel is deflected from the vertical by an angle less than the maximum angle of repose for seeds and is directed in the direction opposite to the direction of movement of the opener, and the outlet openings of the channels are located from each a friend at a distance equal to the required difference in the depth of planting seeds and fertilizers. A roller attachment is installed behind the openers, containing sequentially installed rollers of a loosening and leveling type, an H-shaped frame, brackets, rods, nuts and springs. Ripper roller contains axle and disc rippers. The leveling roller contains an axle, side and intermediate discs, rippers. The rippers are installed in such a way that they form a helical line, the direction of which starts from its longitudinal axis of symmetry and is directed towards the side discs. The rippers are square in cross section and are twisted along the entire length at an angle α relative to their longitudinal axis of symmetry in such a way that the sharp edges of each ripper form helical lines, and the sharp edges of the rippers are directed in different directions from the geometric axis of rotation of the leveling roller.Such a design of the combined sowing unit will improve the quality of sowing grain crops.Полезная модель относится к сельскохозяйственному машиностроению, в частности к сеялкам для посева зерновых культур.Комбинированный посевной агрегат включает раму с прицепным
