ABSTRACT:
This disclosure relates to a continuous excavator for use in open-pit mining, which comprises a self-propelled main frame, a rotating cutter drum supported by pivotal booms and having cutter bits on its outer periphery for excavating the ground material, and a scraper supported behind a lower portion of said drum which collects earth/rock material dug by the cutter bits. An upward conveyor is supported on the frame and slopes upwardly to convey up the earth/rock material from the scraper. Another pivotable conveyor is supported at one end on the frame below the upper end of the upward conveyor, and it is pivotable both horizontally and vertically in order to convey the earth/rock material from the upward conveyor out of the excavator to a desired location.
