Abstract
Disclosed is a conveyor belt/cutting head advancement mechanism (10). Mechanism (10) comprises a conveyor belt support structure (11) connected at one end to a conveyor belt gathering structure (12). The conveyor belt support structure (11) is typically interconnected at its forward end to a self advancing conveyor return end (not shown). Material removed from a mine face by the cutting implement is delivered to a conveyor belt supported by the support structure (11). Structure (11) comprises a plurality of structural elements (18) pivotally interconnected in a scissor-like configuration. The mid points of elements (18) are pivotally interconnected at a point coinciding with the mounting location of a conveyor belt return roller (16). At the upper pivotally interconnected extremities of elements (18), the conveyor belt advancing rollers are supported. Mounted at a location nearby the lower ends of elements (18) are ground engaging wheels (17). The conveyor belt gathering structure (12) comprises a frame (19) within which is mounted a pair of gathering roller groups (21 and 22). One or both of the gathering roller groups may be mounted upon sub-frames which may longitudinally traver…
