RIPPER WITH BIDIRECTIONAL LIQUID ENERGY ACCUMULATOR Russian patent published in 2014 - IPC E02F5/32 E02F9/22 

FIELD: construction.

SUBSTANCE: ripper contains bidirectional liquid energy accumulator, underlying machine, framed suspension with hinged ripper tip mounted on it and elastic system. At that elastic system contains the main cylinder with piston at the rod mounted on the frame and power-operated rod passing through articulated rod and ripper tip. At that the main cylinder is divided by partition into two independent cylinders equipped with main and auxiliary cavity. In auxiliary cavities of cylinders there are installed pistons connected to hollow rods which interact with power-operated rods passing through the main cavities and fixed at inners walls of travelling barrel covering the main cylinder which is connected to ripping rack through a hinge. Auxiliary cavities of each cylinder are equipped with openings from rod side and free piston side, which interact with reversive hydro pump through bidirectional hydraulic locks and pipelines. Besides elastic system is equipped with auxiliary reversive hydro pump which outlet is connected though bidirectional hydraulic locks to openings in walls of the main cylinder cavities while its inlet is connected to pipeline with a tank for liquid storage.

EFFECT: increasing efficiency of soil ripping due to reduction of pulling force and dynamic loads acting on underlying machine and their transfer to the area of soil destruction within the wide range for forced oscillation frequencies of actuating device.
