WORKING EQUIPMENT OF THE RIPPER Russian patent published in 2021 - IPC E02F5/30 

FIELD: earthmoving equipment.

SUBSTANCE: invention relates to rippers for the development of strong and frozen soils. The working equipment of the ripper includes a beam, a ripping tooth mounted on it, side disks pivotally attached to the beam and a hydraulic cylinder for sinking the tooth with a hydraulic distributor. The working equipment of the ripper is fitted with a disc drive hydraulic cylinder with a hydraulic distributor controlled by a hydraulic valve, a hydraulic pulsator and an adjustable hydraulic motor. The hydraulic valves are made with the possibility of communicating, in one of the positions of the spool, the cavity of lifting the hydraulic cylinder of the tooth deepening with the cavity of lowering the hydraulic cylinder of the disk drive, with a hydraulic line, through a controlled hydraulic valve, the control chamber of which is connected to the cavity of lifting the hydraulic cylinder of the tooth deepening, and a hydraulic pulsator with a drive in the form of an adjustable hydraulic motor is attached to the hydraulic line connecting the controlled hydraulic valve with the hydraulic distributor of the disk drive.

EFFECT: increase in productivity and reliability by simplifying the kinematic scheme of working equipment.
