Abstract
A mining machine suitable for cutting roadways in coalmines comprises a cutting head, a conveyor for moving mined material rearwardly of the machine and a discharge conveyor for unloading the mined material to one side of the machine. As the machine advances the discharge conveyor can be used selectively to unload coal onto a stage loader and other material into packholes, thereby saving labor. The discharge conveyor may be pivotable about horizontal and/or vertical axes, longitudinally extendable or movable relative to the machine or cutting head to obtain maximum control over the area in which it discharges material.
Claims12
A mining machine particularly constructed for use in cutting a roadway at an end of a working face, said mining machine having a front and back and comprising a cutting head;
- mounting means for said cutting head including means for moving said cutting head forwardly against a working face to be cut;
- means for conveying mined material towards the back of the machine;
- a discharge conveyor extending in a direction transverse to the front-back longitudinal direction of said mining machine;
- said discharge conveyor having at least one discharge end and mounting means mounting the discharge conveyor on the mining machine for relative movement of said discharge end and said cutting head in the front-back longitudinal direction whereby the cutting head may be advanced towards the working face while the discharge end of the discharge conveyor is maintained in the same location to unload material at the same selected point, and means for extending the discharge conveyor in the transverse direction whereby mined material may be unloaded at selected points disposed at different transferve distances from one side of said machine.
