Abstract

The authors substantiate the design of an excavator’s end effector for joint rock crushing and loading. The structural layout and parameters of hydroimpactors included in the end effectors of mining machines are described. The physical model of the hydroimpactors is constructed, tested and adjusted. The test data on the dynamics and outputs of the model at different power fluid flow rates are compared. The simulation model of the hydroimpactor is constructed and verified using the test data. The capabilities of the hydroimpactors are calculated for the planned modes of operation. For the excavator’s end effectors, it is proposed to use the hydroimpactor design with the lagged return travel of the piston toward the flexible adjustment of the hydroimpactor performance and to reach the required impact capacity at lower flow rates of power fluids.
