DEVICE TO OPEN ROOT SYSTEM OF CLONAL PARENT STOCK Russian patent published in 2011 - IPC A01B39/00 

FIELD: agriculture.

SUBSTANCE: device comprises frame mounted on suspension device with the help of self-aligned parallelogram mechanism with hydraulic cylinder. Disk ploughshares and rotor working elements serially arranged behind them are fixed on frame. Rotor working elements are equipped with elastic pins and drive. Device comprises probe guide blocks installed on "П"-shaped frame arranged in vertical plane. Frame is kinematically joined to hydraulic distributor that controls operation of hydraulic cylinder in parallelogram mechanism. Probe guide blocks are equipped with branch lifting components arranged in the form of aslant three-edged wedges that create a slot with vertical walls at the outlet, and walls penetrate into cross section between disk ploughshares.

EFFECT: design will make it possible to considerably improve quality of opening of root system of clonal parent stocks prior to their separation from stools, since availability of branch lifting components helps to reduce protective area and eliminates damage of sprouts with cutting edges of disk ploughshares.
