摘要:
The utility model relates to the field of agricultural engineering. The combined tillage unit contains a frame, a device for connecting to a tractor, a control mechanism, a support wheel, working bodies containing a stand and a flat-cutting leg. Between the working bodies installed disk section. Behind the working bodies, a roller prefix is installed, containing sequentially installed 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. Provides improved soil cultivation. 3 ill.Полезная модель относится к области сельскохозяйственного машиностроения. Комбинированный почвообрабатывающий агрегат содержит раму, устройство для соединения с трактором, механизм регулирования, опорное колесо, рабочие органы, содержащие стойку и плоскорежущую лапу. Между рабочими органами установлена дисковая секция. За рабочими органами установлена катковая приставка, содержащая последовательно установленные катки, Н-образную раму, кронштейны и штанги. На каждой штанге установлены гайка и пружина. Каждый кат
