Selectively phased water supply of a cutter head

The mining machine can serve a dual function, as a road header or as a continuous miner. The machine has a turrent 14 into which a road header assembly can be directly pivotally mounted. Alternatively a continuous miner cutter assembly can be pivotally mounted on the turret, indirectly via transversely disposed pivot extension brackets 45 which are firstly mounted on the turret to extend the pivot axis forwardly of that of the road header assembly. Each bracket has three bores 46-48 in triangular disposition, two of which 46, 47 fixedly connect the bracket to the turret while the third bore 48, forwardly of the others provide the pivotal connection for the parallel arms 40 of the continuous miner.

An angle station for an endless conveyor belt has an upper and a lower horizontal roller bank disposed in parallel with each other across a framework across the angle station. The angle of entry to the angle station of the upper run is co-linear with the exit of the lower return run. A reversing roller is associated with the lower bank to reverse the direction of the incoming return run before it passes over and around the lower roller bank and a reversing roller is associated with the upper bank to reverse the direction of the outgoing upper run of the belt after it has passed over and around the upper roller bank. The roller banks are interchangeably mountable on the framework to receive a right-handed or left-handed belt. Each roller bank comprises a stationary guide member mounted on a support bar removably mounted on the framework in one of two different attitudes for right and left-handed belts, and the stationary guide members being interchangeably mountable on the support bars for right and left-handed belts. Each stationary guide member has the shape of a major segment of a right circular cylinder with opening therein through which project an array of freely rotatable rollers disposed in a helical path and in an attitude to change the direction of the belt through an angle equal to the lesser angle of entry. Moreover, the pair of guide members have helical paths of opposite hand so the upper guide member for one hand becomes the lower guide member for the opposite hand.
