FIELD: agricultural engineering, in particular, tractor-mounted one-way plows for smooth plowing of various kinds of soils for growing of cereal and industrial crops. ^ SUBSTANCE: tractor-mounted one-way plow has tractor-mounted transverse hanger beam with vertical column, one-way frame with pin pivotally connected to hanger beam for rotation relative to one another in vertical plane, left-handed and right-handed plow bodies fixed at both sides of frame, carrier wheels, and frame reversal rotation device including actuating mechanism cooperating with frame, and drive made in the form of hydraulic cylinder whose center is pivotally connected with vertical column of hanger beam, and stem pivotally connected with actuating mechanism. Actuating mechanism of frame reversal rotation is made in the form of chain transmission with reducing transmission ratio. Drive sprocket of chain transmission is pivotally fixed on shaft secured in horizontal position on vertical column of hanger beam. Driven sprocket is rigidly put onto shaft of rotary frame, and hydraulic cylinder stem is pivotally connected to drive sprocket through pivot eccentrically fixed on disk of drive sprocket. ^ EFFECT: provision for converting progressive motion of hydraulic cylinder stem to rotary motion of frame through simple transmission of rotation and, accordingly, enhanced reliability in operation. ^ 5 dwg |
