ABSTRACT:
A scraper for earth moving purposes including an open-fronted bowl formed of a pair of laterally spaced vertical side sheets having a fixed floor section at the rear thereof, and a blade base at the front, defining a discharge opening between them. A rolling frame supported by guide tracks normally closes off the discharge opening. A substantially continuous flexible floor structure overlies the rolling frame to support the soil in the bowl. The floor structure is made up of a set of articulated strips supported on a roller train, with the leading end of the roller train passing around the front end of the rolling frame through 180.degree. so that when the leading end is pulled by an actuator the rolling frame is retracted to uncover the discharge opening. In the preferred embodiment an ejector plate is connected to the trailing end of the roller train so that continued movement of the roller train causes the ejector plate to conduct the soil from the back of the bowl for discharge into the opening.
