装置。[Scope of Claim for Utility Model Registration] In a sand settling device that scrapes up sediment accumulated in a sand settling basin with a bucket attached to an endless chain, the upstream and downstream sides of the settling basin are independently oscillated in a vertical plane. A freely movable upstream swinging arm and a downstream swinging arm are provided, and a part of the endless chain is attached to a sprocket provided at each tip of the upstream swinging arm and the downstream swinging arm. The upstream swinging arm is spanned so that it is unsupported, and the swinging fulcrum shaft of the upstream swinging arm is such that the resultant force of the endless chain acting on the tip of the upstream swinging arm always lifts the upstream swinging arm. The downstream swing arm is installed at a position where it acts in the direction, and the swing fulcrum shaft of the downstream swing arm is such that the resultant force of the endless chain acting on the tip of the downstream swing arm always pushes down the downstream swing arm. What is claimed is: 1. A sand settling and scraping device, characterized in that it is installed in a position where it acts in a direction, and that an elevating device for the downstream swinging arm is connected to the downstream swinging arm.
