FIELD: mining industry.
SUBSTANCE: device has rotating device, impact device and axial support, as well as mounting frame, made to be supported by feeding beam by sliders on frame and meant for mounting a rotation device on it together with impact device and containing an axial support, by means of which mounting frame is made with possible receiving of forces of feeding and outputting, affecting drilling hammer, and transferring them to feeding bar and feeding equipment. At least rotating device or impact device is a single replaceable module, and axial support has at least one contacting surface for mounting of replaceable module and, respectively, its dismantling without any other dismantling of drilling hammer construction. Mounting frame is a portion of drilling hammer, contains means for connecting rotating device and impact device belonging to drilling hammer, and sliders, fixed to mounting frame for mounting of mounting frame and whole drilling hammer on feed bar, and at least one contact surface, meant for mounting of replaceable module of rotating device and/or impact device.
EFFECT: simplified construction, higher reliability and durability.
