摘要：
The utility model relates to agricultural machinery, in particular, to tools for surface cultivation of the soil. The combined tillage unit includes a frame consisting of a central and side sections, the length of the side sections being equal to the length of the central frame, interconnected by mechanisms from the working position to the transport and vice versa, transport and support wheels, working bodies in the form of lancet paws. The working bodies are mounted on the frame in a staggered manner with the ability to adjust their position in height relative to the lower points of the support wheels and fixation in the required position. Roller consoles are connected to the central and side sections of the frame. Each roller attachment contains 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. combined tillage unit will improve the quality of tillage.Полезная модель относится к сельскохозяйственному машиностроению, в частности, к орудиям для поверхностной об
