The scraper consists of a bucket with a soil-shoveling mechanism composed of a bucket body, a cutting edge, 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 the sliding baffle are arranged at the opening of the bucket body, and the two are connected by a hinge. The outermost ends of the hinge shafts are inserted into the sliding grooves at the front end of the bucket body and can move along the sliding grooves; the cutting edge is welded and fixed at the front end of the bottom of the bucket body, and the soil-breaking knife is welded and fixed on the cutting edge; the support mechanism is used to control the lifting of the sliding baffle and the rotating baffle. When the scraper shovels and transports ore in the underground ore pile, there will be a collision between the limit block of the bucket and the boom of the scraper. Since both the limit block of the bucket and the boom of the scraper are rigid structures, long-term collision during use will damage the boom structure of the scraper, accelerate the wear of the scraper, increase the usage loss rate of the scraper, require frequent maintenance, and delay the entire working cycle in the long run, which is not conducive to production use.
