Bed scraping apparatus for efficient bulk material dumping
First Claim
1. Apparatus comprising:
- a transportation vehicle including a vehicle frame,a dump body on said vehicle frame and configured to be lifted at one end from said vehicle frame, with a dump opening at an opposite end of said dump body, said dump body further comprising a floor;
a scraper assembly longitudinally movable along said floor, and,at least one first pivoting connection on said scraper assembly,at least one second pivoting connection on said vehicle frame,at least one link between said first pivoting connection and said second pivoting connection, said link further comprising a first stop positioned on said link at a point of partial inclination of said dump bed to automatically urge said scraper assembly to begin a scraping stroke along said floor toward said dump opening, with further inclination of said dump body beyond said point of partial inclination pulling said scraper assembly toward said dump opening, thereby scraping material floor free of undumped or clumped said material.

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.

23. Apparatus for scraping clumped material in a dump bed free comprising:
-
a vehicle frame, a dump body comprising a floor, and one end that is lifted to induce inclination of said dump body, thereby dumping material from a dumping end said dump body, a scraper assembly on said floor of said dump body, said scraper assembly having a frame and a plurality of scraper blades that scrape said floor, said scraper assembly movable from a first position wherein one end of said scraper assembly thereof is adjacent said one end to a second position wherein an opposite end of said scraper assembly is adjacent said dumping end of said dump body, a first extensible link extending through a first slot in said dump body and connected between said frame and one side of said scraper assembly, a second extensible link extending through a second slot in said dump body and connected between said frame and an opposite side of said scraper assembly, said first extensible link and said second extensible link configured to move said scraper frame automatically at a selected inclination and a selected declination of said dump body. - View Dependent Claims (24)
