CONTINUOUS-OPERATION EXTRACTION MACHINERY FOR STRIP MINING WITH A CYLINDRICAL EXTRACTOR |
摘要 |
A continuous-operation extraction apparatus for strip mining that is self propelled on continuous track treads. A cylindrically-shaped cutting extractor has cutting tools arranged on its peripheral surface. Recesses are provided in this peripheral surface for the transfer of extracted material through a chute to a first conveyor that is located axially within the cylinder of the cutting extractor. A second conveyor having loading carts connects with the first conveyor and receives the loosened material from the first conveyor. The first conveyor has an inside section which emerges from a front side of the cylinder and merges outside into a sloping conveyance section which extends vertically to substantially an upper edge of a chassis. An overhead ascending section is connected to the inside section and terminates in a transfer region where the extracted material is transferred to the second conveyor.
