<p>Apparatus for the handling of dislodged particulate material within a mine includes a base member having ground traction means with a body member supported on the base member. Vertical side plates on opposed sides of the body member secured thereto define a longitudinal material receiving bin. An endless main conveyor located within the material receiving bin has a receiving end and a discharge end. The receiving end when used as a surge hopper is adapted to continuously receive material dislodged from an adjacent continuous mining machine. A delivery conveyor receives material from the discharge end of the main conveyor and discharges it into other conveying means such as a shuttle car or an endless belt conveyor. A portion of the main conveyor positioned adjacent the discharge end thereof moves or pivots upwardly about a transverse horizontal axis and thereby assumes a position for maximum discharge of the material. Another position is provided for terminating discharge of material and intermediate positions for intermediate rates of discharge. A sensing device is provided to determine the quantity of materials in the material receiving bin and control the elevation of a portion of the main conveyor to thereby regulate the rate of discharge in the material receiving bin and the angle of inclination of a portion of the main conveyor. The endless main conveyor operates continuously during the operation of the mining machine and continuously advances and distributes the load in the receiving bin and discharges material from the receiving bin only when a shuttle car is in material receiving position.</p> |
