FIELD: mining.
SUBSTANCE: drilling tool emitter contains piston of emitter, pressing punch and drill blade chassis to breed before applying the shock piston-drummer for drill shank and moves them from slaughter by turning the drilling tool, and also has a sleeve and gap metering the flow of compressed air into the ADF total submission. The air distribution unit of the perforator has a play and freedom of movement in the puncher body and functions as an emitter piston rigidly attached to the lead screw-rod, and the function of compressed air emitter of bushing-doser, passing through the calibrated slot.
EFFECT: effective transfer of the kinetic energy of the impact of the piston of a perforator to the destruction of rock and the inclusion of automatic selection of the rational value of the force of pressing the hammer body to the face.
