Abstract
An apparatus for continuously unloading bulk material from a bulk container has a carriage displaceable longitudinally adjacent the bulk container and an outrigger having an inner end pivotable about longitudinal and vertical axes on the carriage and an outer end. A conveyor extends between the ends of the outrigger. An arm has an upper end pivoted about a horizontal axis on the outer outrigger end and a lower end engageable in the container and contains a bucket conveyor. A pair of augers of opposite hand are mounted on the lower arm end and rotate to draw in the bulk material and pass it to the bucket conveyor.
Claims19
An apparatus for continuously unloading bulk material from a bulk container, the apparatus comprising:
