COMBINED PULSE AND MECHANICAL ACTION DEVICE FOR GROUND CRUSHING Russian patent published in 2019 - IPC E21C45/04 E21C25/60 

FIELD: machine building.

SUBSTANCE: apparatus for crushing rock of combined pulse and mechanical action, consisting of a leading rail, a shield hydraulic cylinder, a power block of a hydraulic shock, a drill rod, a drilling head, unit of dynamic compactor, static sealing couplings, spring rings, static sealing rings, dynamic sealing rings and support platform of drilling head. Support platform of drilling head is fixed on drive rail, housing of shield hydraulic cylinder is pivotally connected to driving rail, rod of piston of shield hydraulic cylinder is hingedly connected to housing of power unit of hydraulic impact, which is fixed on drive rail with possibility of sliding, driven shaft of power block of hydraulic impact is connected to one end of drilling rod by means of threaded connection, and other end of drill rod is connected to drilling head by means of threaded connection, drilling rod passes through hole in support platform of drilling head, dynamic compactor unit is attached to screws to power hull power unit casing, pressure seal unit high-pressure water inlet, water hose inside hydraulic unit power drive driven shaft high-pressure, water conduit inside the drill rod, water conduit inside the drilling head and generative cavities of each pulse spherical button are connected in series, and static sealing couplings are rigidly fixed by means of spring rings on the ends of the drill rod, which are connected to the driven shaft of the power unit of the hydraulic shock and the drilling head respectively.

EFFECT: effective rock crushing, reduced level of dusting, longer service life, higher safety and efficiency of deposit development.
