  • Patent number: 4026423
    Abstract: An improved bulk extracting apparatus comprises a pivoted chain scraper conveyor which in the horizontal position acts to remove material from the transverse face of a dump. Various clearing means are provided to loosen material from the face of the dump which is then carried by gravity to feed the scraper conveyor. Alternatively, the scraper conveyor may be pivoted upwardly to clear the dump so that the apparatus may be easily moved either to a different dump or to a different position on the same dump. The scraper conveyor may also be partially lowered to act to remove material from a lateral side of the dump. Finally, stacking means may be additionally provided for adding material onto the dump such as for mixing purposes.
