Abstract
A continuous mining machine having a cutter head moveably mounted on a support guide with a center portion extending across the width of a carrier. The support guide has hinged end portions so that the end portions may be swung against the side of the carrier in order that the machine may be maneuvered in restricted areas. A gathering conveyor is positioned beneath the support guide and comprises two wing portions which may also be swung against the sides of the carrier.
Claims6
a continuous mining machine having a moveable carrier, a cutter head, a horizontal support guide extending across the front end of said carrier for supporting said cutter head for slideable movement thereon, a gathering conveyor extending across the front end of said carrier parallel to and beneath said support guide, and a flight conveyor extending over the length of said carrier to convey material received from said gathering conveyor;
- the improvement comprising in that a guide end portion of said support guide is adapted to extend over a side edge of said carrier, and in having a guide hinge with a pivot point positioned beyond the side edge of said carrier for supporting said guide end portion whereby said guide end portion may be moved from a position extending across the carrier to a position extending along a side of the carrier.
A continuous mining machine comprising a moveable carrier, a horizontal support guide mounted on said carrier for vertical movement with said support guide having a center guide portion extending across the width of said carrier and an end guide portion at each end of said center guide portion, a rotatable circular cutter head moveably mounted on said support guide, means for rotating said cutter head, means for moving said cutter head along said support guide, means for moving said support guide vertically, and guide hinge means located beyond the side edges of said carrier and supporting said end guide portions whereby said end guide portions may be moved from a position extending parallel to said center guide portion to a position extending along a side of the carrier.
