DEVICE FOR DEHISCENCE ROOT SYSTEM OF VEGETATIVELY PROPAGATING TREE STOCKS

FIELD: agriculture. ^ SUBSTANCE: device for dehiscence root system of vegetatively propagating tree stocks prior to their division from parent plants relates to agricultural engineering and can be used for mechanisation of horticultural operations. The device comprises a frame mounted on a hitch with the help of self-adjusting parallelogram mechanism, weed removing units mounted on the frame, following them rotary tools with inclined rotation axis and flexible elements, drive and copying discs. Parallelogram mechanism is fitted with a multiplier comprising hydraulic cylinder and hydraulic distributor which controls it from copying discs by drive connection. Weed removing units are designed as free rotating concave discs mounted on the frame by poles and holders. Rotary tools are of truncated cone shape and are fitted with flexible elements. Drive connection between copying discs and hydraulic distributor comprise work carriers which are forward-directed to the line of motion and connected to the frame by beams with a lag hinge and a lever that are set between stoppers of two spring-tightened rocking arms with limiters. Beam lever is connected to the valve of hydraulic cylinder by a connecting rod with compensator. Hydraulic cylinder is made with underlapping chambers. ^ EFFECT: improving quality of dehiscence root system of vegetatively propagating tree stocks prior to their division from parent plants. ^ 5 cl, 5 dwg
