Abstract

The invention is referring to a pneumatic perforator for drilling in mining industry having a head cylinder including the admission valve of the compressed air and the water washing installation for the perforated hole washing, characterized by that the perforator is provided by a quick change of the rotation speed device (B) which's line grooved bushing (8) placed in a gear's hub (9) is driving an pipe shaft (16) provided by idlers (17, 18, 19) geared by the steering wheels (22, 23, 24) fixed on the rotation bushing (25) in which is pressed the drill-bushing (30); its rotation speed is selected by a mobile peen (31) assembled in the rod (32).
