RIPPER WITH GAS ENERGY ACCUMULATOR OF BILATERAL ACTION Russian patent published in 2015 - IPC E02F5/30 

FIELD: mining.

SUBSTANCE: ripper differs from the known in that the fixed gas cylinder is provided with a movable gas cylinder, which piston is connected to the piston of the fixed gas cylinder with the rod. The axis passes through the rod, coupled with a sleeve covering the cylindrical housing and interacting through the joint with the ripper tip. The movable gas cylinder is connected to the rod of the hydraulic cylinder, arranged in the cylindrical housing on the opposite side of the ripper tip. The cavities of the movable and fixed gas cylinders are communicated through the air ducts and the air line with a reversing pneumatic compressor and pilot-operated check valves of bilateral action, and the cavities of the hydraulic cylinder are connected through the channels located in the housing of the hydraulic cylinder, and the hydraulic drive with the reversible hydraulic pump and the pilot-operated check valves of bilateral action.

EFFECT: invention enables to improve the efficiency of loosening soil by reduction of traction force and dynamic loads acting on the base machine, and transfer them to the zone of ground destruction in a wide range of variation of frequency of forced oscillations of the working body, and also to carry out the adjustment of operation of the mechanical system in case of frequency mismatch.
