Hydraulic percussive shearing tool for planetary cutting head of mining machine

It is required to design small-size heading machines for disintegration of strong rocks. A mineral body can be prepared for breaking by multiple point impacts delivered along an epicycloid. As an engineering decision to the problem, it is proposed to introduce a new assembly of a percussive shearing drum with a ram-type tool. The planetary percussive shearing head of a mining machine is presented. The construction design and kinematic structure are developed for the planetary percussive shearing head of a mining machine for destruction of strong rocks, and its operating principle is described. The equations of motion are derived for each tool of the planetary percussive shearing head. For the implementation of the proposed construction design, the hydraulic percussive shearing tool is developed. The kinematic structure and the basic elements of the hydraulic percussive shearing tool are presented. The mode of operation of the hydraulic percussive shearing tool is described. It is necessary to expand the application range for the method of disintegration of strong rocks using hydraulic impactors which ensure prolonged action of the power pulse. The modular design of the tool allows replacement of unified power modules.
