Scraper is an integrated machinery for shovel and soil transportation. The key point of the present invention is to design a bucket with a shovel mechanism composed of a bucket body, a shovel blade, a soil breaking knife, a rotating baffle, and a sliding baffle, and a support mechanism composed of a front support rod, two side support rods, and a baffle support rod. The rotating baffle and sliding baffle are set at the opening of the bucket body, and are connected by hinges. The two ends of the hinges are inserted into the sliding groove at the front end of the bucket body, and can move along the sliding groove. The shovel blade is welded to the front end of the bucket bottom, and the soil breaking knife is welded to the shovel blade. The bracket mechanism is used to control the lifting of sliding and rotating baffles. The present invention has a simple structure, high construction efficiency, and is suitable for river construction, dam construction, and post flood dredging.
