RIPPER OF DIGGING MACHINE Russian patent published in 2017 - IPC E02F5/32 

FIELD: construction.

SUBSTANCE: ripper of a digging machine comprises a lever connected to the frame of the machine by means of hinges, each of which has a horizontal axis, with a ripper tooth attached to the end of the lever at an angle to it, and a hydraulic cylinder for lifting and lowering the ripper lever is hingedly connected to it and to the frame, so that its longitudinal axis in the working position of the ripper makes up an angle of 80-100° with the plane passing through the horizontal axis of the hinges connecting the lever with the frame. In addition, the ripper of the digging machine can be provided with a mechanism for relative displacement of the hinge fixing the lever to the machine frame and/or at least one of the hinges connecting the hydraulic cylinder to the frame or to the ripper lever.

EFFECT: ensuring the stabilisation of the vertical position of the cutting tooth part while changing the resistance to soil loosening due to eliminating the eccentric action of the reactive forces, it is also possible to transfer to the ripper a greater force generated by a basic digging machine without reinforcing the supporting ripper part, which increases the efficiency factor of a digging machine as a whole.
