Mobile dual auger continuous mining machine with multiple movement capabilities

摘要

A continuous mining machine comprising a cutter assembly including a cutter frame, a pair of oppositely pitched independently vertically movable auger cutters having their axes of rotation disposed generally parallel with respect to one another, a mobile assembly disposed rearwardly of the cutter assembly and including a mobile frame having a pair of parallel power driven endless track units mounted thereon for independent pivotal movement of each unit about a common generally transversely extending horizontal axis disposed adjacent to the forward portion of the track units, a yoke assembly between the mobile assembly and the cutter assembly including a yoke frame pivotally interconnected with the mobile frame for pivotal movement about an axis generally parallel with the common pivotal axis of the track units and pivotally interconnected with the cutter frame for pivotal movement about a generally upright axis extending generally perpendicularly to the pivotal axis of the yoke frame with the mobile frame, and conveyor means including a forward section carried by the cutter frame and a rearward section carried by the mobile frame for conveying coal cut by the auger cutters longitudinally rearwardly of the machine, the forward portion of the rearward conveyor section being mounted on the mobile frame for pivotal movement about an axis parallel to the common pivotal axis of the track units.
