摘要：
The utility model relates to agricultural machinery, in particular to tillage units for surface presowing cultivation of the soil.The combined tillage unit includes a frame, a device for connecting to a tractor, control mechanisms, support wheels, working bodies containing a rack and a flat-cutting leg, disk sections. Disk sections are installed in front of the working bodies. Each disk section contains a frame, an axis and spherical disks, and the disk sections are mounted at an angle to the direction of movement of the tillage unit. Behind the working bodies mounted tillage mill. A roller attachment is installed behind the tillage cutter, containing sequentially mounted rollers, an H-shaped frame, brackets and rods. A nut and spring are installed on each rod. Each roller contains an axis, side and intermediate disks mounted on the axis at equal intervals in the horizontal plane, rippers. On the periphery of the side and intermediate discs, triangular recesses are made. The rippers are mounted in triangular recesses of the side and intermediate discs so that they form a helical line. The direction of the helical line of the front roller starts from its longitudinal axis of symmetry and is directed towards the side discs. The direction of the helical line of the rear roller starts from the side discs and is directed to the longitudinal axis of symmetry of the roller. The rippers in the cross section are square and twisted along the entire length by an angle α relative to their longitudinal axis of symmetry so 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 axes of rotation of the rollers installed in series.Such a design of the combined tillage unit will improve the quality of pre-sowing tillage.Полезная модель относится к сельскохозяйственному машиностроению, в частности к почвообрабатывающим агрегатам для поверхностной предпосевной обработки почвы.Комбинированный поч
