COMBINE WITH DRUM ACTUATOR FOR UNDERGROUND MINING WITH IRRIGATION SYSTEM Russian patent published in 2012 - IPC E21C35/22 

FIELD: mining.

SUBSTANCE: combine with a drum actuator for underground mining comprises a body, brackets for fixation of cutting rollers for each direction of combine travelling, driven motors for combine movement, a system of combine water supply. The system of combine water supply comprises a common source of water supply for water circulation loops, valves for connection and disconnection of water circulation loops, a cooling water circulation loop and an irrigation system. The cooling water circulation loop serves for cooling of driven motors. The irrigation system comprises at least one irrigation water circulation loop with an appropriate supply pipeline for tools of cutting rollers. In each return pipeline of the cooling water circulation loop there is one disconnection valve installed as connected to one of supply pipelines. A switching valve serves to supply cooling water via it, if required, to cutting rollers as irrigation water.

EFFECT: increased efficiency of water supply systems of a combine with a drum actuator.
