Abstract
An improved rotating disc-type gathering head suited for use with underground mining machines includes at least two gathering discs mounted for rotation on an inclined apron in positive engaging relationship at their point of tangency. One of the discs is rotatably driven, preferably by means mounted above the apron. The second disc is rotated in the opposite direction by the first disc to provide the desired flow of mined material. In the preferred embodiment the discs have peripherally disposed intermeshing gear teeth, and the drive means comprises a pinion gear in peripheral engagement with the first disc. Additional gathering discs can be added without complicating the simple mechanical drive system below the apron.
Claims16
An improved gathering or loading device for moving loose material, such as mined coal or the like, to other means associated with the device, such as a conveyor, wherein the device comprises:
- a base having an inclined apron extending from the back of the device downwardly to a plow-like leading edge;
- at least two large circular discs mounted for rotation on the base in a common plane generally flush with the apron and in positive engagement with each other at their point of tangency;
- and
- drive means for rotating a first of the discs whereupon the first disc turns the second disc in the counter rotational direction, the arrangement and rotational directions of the discs being such as to move the loose material from front to back of the base and to the associated means.
A gathering device particularly suited for use with a continuous mining machine to gather the mined material and feed it to means associated with the miner for conveying the material away from the mine face, comprising:
- a base adapted at one end for connection to the mining machine adjacent one end of the conveying means and having an inclined apron sloping down and away from the one end to a plow-like leading edge at the other end;
- at least two generally flat circular discs mounted for rotation on the base in a common plane generally flush with the apron and on opposite sides of the forwardly projected centerline of the conveyor means, the discs being in positive engagement with each other at their point of tangency;
- and
- means mounted on the base for rotating one of the discs whereupon the one disc in turn effects counter rotation of the other disc, the arrangement and rotational direction of the discs being such that mined material on the device is moved toward the center and back of the apron to the conveyor means.
A gathering or loading device for moving loose material, such as mined coal or the like, to other means associated with the device, wherein the device comprises:
- a base having a sloping apron surface extending from the back of the device downwardly to a plow-like leading edge;
- a plurality of large circular discs rotatably mounted on the base in a common plane generally flush with the apron surface, at least two of the discs being in positive peripheral engagement with each other, a first of the two discs being rotatably driven and in turn driving the second of the two discs in the counter rotational direction, means in peripheral engagement with each of the remaining circular discs to rotate each of the remaining discs in the same direction as the closest of the two discs, the arrangement and rotational direction of the discs being such as to move the loose material toward the two discs and along their adjacent perimeters to the rear of the device.
