ABSTRACT:
A mining apparatus which is adapted to be connected to a sectioned powered auger conveyor assembly and driven by the central shaft of the auger is constructed with its housing divided into a cutting section and an attachment section. A drive shaft is rotatably mounted to the cutting section and a transmission is mounted to the drive shaft, the transmission being adapted to receive an input shaft having one end coupled to the auger central shaft so that the auger shaft will turn the input shaft and drive the shaft through the transmission. A plurality of cutting arms are rotatably mounted on the drive shaft and are pivotally rotated around the drive shaft by a plurality of hydraulic cylinders to move the arms which carry an axle mounted therein on which cutting drums are mounted enabling the cutting drums to cut material from a seam of material. The cutter drums mounted on the axle are driven by a plurality of chains connecting the cutting drum axle to the drive shaft and a conveyor assembly is mounted under the arms and is also adapted to be driven by the drive shaft so that material fragments cut from the seam are deposited and carried onto the conveyor belt and transported along the conveyor belt into the auger conveyor which carries the material back through the auger conveyor to the desired site.
