Mechanically driven drilling device with a rotary distributor.

摘要

The invention refers to a rotary reciprocating/percussive drilling device designed for boring mine shafts used for displacement and excavating usable rock and ore materials from the solid, by means of a technology based on boring and bursting. The distribution system for the compressed air is achieved by means of a fixed distributor head (7) and a rotary distributor (8) designed with radial apertures and longitudinal ports, by means of which the compressed air is fed to the front and rear spaces of the pistons, thus displacing them, and the rotation of the distributor is induced by means of a mechanical transmission system.
