DEVICE FOR DISCLOSURE OF ROOT SYSTEM OF CLONAL ROOTSTOCKS

摘要

FIELD: agriculture.;SUBSTANCE: device comprises a frame mounted on the hitch attachment with the self-aligning parallelogram mechanism having a hydraulic cylinder, and a hydraulic distribution valve controlling it from copiers through kinematic connection, with the slide valve overlap. Weed removing units are mounted on the frame and behind them there are rotary working bodies with elastic elements and a drive. Over the rotary working bodies the retaining discs with fingers are mounted. The hydraulic cylinder of the parallelogram mechanism is equipped with a cage of valves containing two shutoff and pressure reducing valves. The weed removing units are equipped with bumpers made in the form of a plate mounted on the inside of the weed removing unit with its front part in the plane of its furrow cutting and rejected at 1-2° horizontally in the direction of the adjacent bumper.;EFFECT: invention enables to improve the quality of disclosure of root system of clonal rootstocks before their separation from the mother plant.;5 dwg
