ABSTRACT:
A dump bed scraping apparatus is disclosed. A scraper portion includes a frame on a floor of an inclinable dump bed that extends the width of the dump bed, and which supports a plurality of scraper blades movably disposed in forward and rearward directions along a floor of the dump bed so as to scrape substantially the entire floor of the dump bed clear of clumped material when the dump bed is inclined. Movement of the frame is facilitated by extensible links attached between a stationary frame supporting the dump bed and members of the scraper frame, which serve to move the scraper frame and scraper blades when the dump bed is inclined and lowered. A pivoting connector attaches one end of the extensible links to the scraper frame through a slot in the dump bed.
