摘要：
The invention relates to the agricultural industry, in particular for the small-sized self-propelled manual tillage machines driven by an electric motor, and can be used for soil cultivation in greenhouses and home gardens. The technical result consists in providing fine tuning of V-belt variator by a predetermined ratio when selecting tillage cutter translational speed by allowing its adjustment handwheel rotation when the motor is running. The technical result is achieved in that the self-propelled soil tillage cutter includes a motor disposed in connection with the housing half-frames, on a central shaft which is mounted overload clutch kinematically associated chain transmission from the motor shaft, the bevel pinion kinematically connected with the toothed conical wheel mounted on the drive shaft fixed at its ends and working bodies freely rotating hollow shaft with the worm mounted thereon, which kinematically with Yazan worm wheel mounted on the semi-axis with its ends fixed to the road wheels. At one end of the hollow shaft is mounted a driven V-belt pulley of the variator V-belt mechanism kinematically coupled with a drive pulley mounted on the motor shaft. The mechanism for controlling the transmission ratio of the V-belt CVT comprises axial holes disposed in the fixed part of the driving pulley pushers in contact with one side of the movable portion, and on the other side - with the handwheel. Additionally inputted intermediate shaft with a threaded portion at one end is pivotally connected by means of a radial bearing with a shaft of electric motor, and the other end - rigidly with poluramy. Handwheel, slidably mounted on the threaded portion of the intermediate shaft, is pivotally connected by means of an axial bearing tappets. 4 yl.Полезная модель относится к сельскохозяйственному машиностроению, в частности к малогабаритным самоходным ручным почвообрабатывающим машинам с приводом от электродвигателя, и может быть использована для обработки почвы в теп
