ABSTRACT:
A drum- or barrel-unloader comprising a stand for supporting a drum or barrel in right side up and inverted orientations, and an elevator for engaging the stand. The stand includes a hopper for receiving the drum contents when the drum is inverted. The hopper is mounted for both gross and fine adjustment between a first position away from the top of the drum, and a second position in engagement with the top of the drum. Gross adjustment of the hopper is provided by inserting an apparatus into aligned holes in two slidably engaged channel sections. Fine adjustment of the hopper is provided by a threaded apparatus on each of two threaded studs, each of which extend from an end of a channel section and are inserted into an apparatus for providing holes on generally opposite sides of the hopper. For fine adjustment the threaded apparatus are loosened and tightened on the threaded studs against the apparatus for providing holes. The elevator comprises first and second frame portions. Upon actuation of a jack between the two portions at least one block on either the elevator or the stand engages at least one trunion on the other of either the elevator or the stand to suspend the stand pivotally from the elevator so it may be inverted. Disengagement of the elevator leaves the stand and drum supported therein in an inverted orientation. The hopper is provided with a material transfer pump and a vent with a filter.
