Scraper bucket for underground workings

摘要

The scraper bucket has a bottom panel (6) with a free scraping edge, two side panels (8) and a rear panel with a coupling mechanism for joining it to a machine with lifting and tilting systems. The bucket has a wheel (15) on each side, turned about horizontal pivots on the side panels to deploy them below the bottom panel for transport and tipping, or to retract them for scraping and loading. The bucket has a scoop (21) for filling it and ejecting its contents, movable lengthwise inside the bucket and dividing it into front and rear sections. Each side panel has a recess (8a) for a wheel, and the scoop forms a partition inside the bucket adjacent to the ends of the two recesses.
