揚機。 A bucket conveyor, which is wound and driven by a drive sprocket installed at the top of the sand settling basin, is guided by being wound around between driven sprockets installed at the lower ends of a pair of swing arms, and is raised and lowered by swinging both swing arms. It is possible to dispose it in a sand settling pond, and when working to scrape up sand accumulated on the pond bottom, the section of the path of the chain conveyor between the two driven sprockets is lowered to a position where it crawls on the pond bottom, and when not working, the chain conveyor's In a siltation prevention type sand scraper that raises a section to a position where it will not be buried in sediment, the pair of swing arms are oscillated in a direction in which the lower ends of each of the swing arms provided with the driven sprocket are separated from each other during non-operation, and The position of the swing fulcrum of each swing arm and the length of each swing arm are determined so that when each swing arm swings, each driven sprocket at the lower end thereof is at approximately 45 degrees with respect to the straight line connecting these two driven sprockets. A siltation prevention type sand raking machine characterized by having a position and length that moves along a trajectory close to intersecting straight lines.
