DEVICE FOR OPENING root system vegetatively propagated rootstocks

摘要

FIELD: agriculture.;SUBSTANCE: device comprises a frame mounted on a suspension device with the help of a self-aligned parallelogram mechanism. There are disc ploughshares fixed on the frame, and downstream there are rotor working elements and stabber feelers. Rotor working elements are equipped with elastic elements and a drive. Stabber feelers are equipped with branch lifting devices with vertical walls at the outlet, which are installed on a "П"-shaped frame arranged in the vertical plane. The "П"-shaped frame is kinematically connected with a hydraulic distributor that controls operation of the cylindrical cylinder. The device is equipped with guides installed in a range between disc ploughshares and rotor working elements. Guides are made in the form of bars fixed on brackets to the frame in direction of motion and creating a vertical slot with a socket in its beginning and embracing cutting edges of the ploughshares. Vertical walls of the branch-lifting devices on stabber feelers are equipped with slots, where front bent ends of guide socket bars enter.;EFFECT: invention will make it possible to considerably improve quality of opening of a root system of clonal parent stocks prior to their separation from stools, since availability of guides helps to reduce protective area and eliminates damage of sprouts with cutting edges of disc ploughshares and rotary parts of rotating working elements.;3 dwg
