  • Soil spreading scraper device including deflecting paddles
    Patent number: 10358790
    Abstract: A soil spreading scraper device has a cutting blade to cut soil from the ground and a rotating impeller member for spreading the cut soil as the frame is displaced forwardly. The impeller member includes a main disc body and a plurality of impeller blades on the main disc body which are pivotal relative to the body between a working position in which the blade body extends in a direction of the impeller axis away from the main disc body and a deflected position in which the blade body extends in a circumferential direction of the disc body in a trailing relationship relative to the pivot axis of the blade body. An actuating assembly resists displacement of the blade body into the deflected position until pressure on the paddle exceeds a prescribed holding force. A spring biases the body to return to the working position.
