Scraper having forwardly swingable apron and full width pivoted striker

Abstract

A scraper for earth moving purposes having an open fronted bowl including a pair of vertical side sheets and a back wall with a floor extending between the side sheets. The bowl is secured to the tractor by a pair of draft members which extend upwardly and forwardly for connection to the draft frame of the tractor. Bowl actuators coupled to the front end of the bowl support it at a selected predetermined level with respect to the draft frame. A pivoted strike off member is hinged in fixed position along the front edge of the floor and extending the full width of the bowl. An apron of arcuate shape and having vertical side plates is pendulously pivoted at the front of the bowl and provided with actuator means for swinging the apron between (a) an enclosing position, (b) a partially open soil retaining position, and (c) a fully open and upraised position creating a large discharge opening ahead of the floor. The strike off blade is moved from a horizontal position to its working position incident to movement of the apron from enclosing position to partially open position for full width scraping of the soil. The back wall of the bowl is forwardly movable by an actuator so that when the apron is moved to its fully open position the contained soil is forwardly ejected for discharge of the soil through the discharge opening.
