  • Patent number: 4300673
    Abstract: Apparatus facilitates the transfer of material from the discharge zone of one mine conveyor onto another conveyor extending perpendicularly to the first conveyor. The transfer apparatus can take the form of a rotatably driven disc disposed beneath the elevated discharge zone of the first conveyor so that the material falls onto the disc. The disc extends over the other conveyor. A scraper lies across the disc to scrape and guide the material into the other lower conveyor. Alternatively, the disc or a modified equivalent component is made stationary while a single scraper or several such scrapers rotate over the disc. The transfer apparatus can also take the form of a curvilinear trough or chute onto which the material falls from the elevated discharge zone of the first conveyor and is guided to the other conveyor. Several driven rollers or paddles or a scraper-chain assembly then impell the material along the chute.
