If you ever dragged the edge of a bucket to collect sand at the beach you essentially worked similar to a Scraper. A scraper has a large hopper or bowl at the back that can be lowered up and down depending on how much material is needing to be removed. As the scraper drives forward the bowl’s edge drags along the surface collecting the material in the bowl. When the bowl is full a hydraulic lift can push forward and dump out the contents.
