ABSTRACT:
An automatic clean-out for the charging bin of an asphalt mix bucket elevator provides for removal of material from the bottom of the charging bin so that hardened asphalt mix will not interfere with operation of moving elevator parts upon subsequent restarting. The clean-out device comprises a pusher having an upright front surface and a flat top surface, with a length and width to overlie substantially the whole bottom area of the charging bin. The pusher is actuated forwardly and rearwardly by a double-acting pressure fluid cylinder jack mounted behind it. In moving forward, the pusher expels mix from the bottom of the charging bin through a front opening therein. It is rearwardly withdrawn through a closely fitting opening so that asphalt mix resting on its top is scraped off to remain in the charging bin.
