[0002] A scraper is a type of trackless equipment in mines, widely used in mining and transportation in underground mines. It is an integrated machine for shoveling and transporting soil. The scraper consists of a bucket with a shoveling mechanism consisting of a bucket body, a shovel blade, a breaker knife, a rotating baffle, and a sliding baffle, and a support mechanism consisting 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 shafts at both ends of the hinge are inserted into the slide groove at the front end of the bucket body and can move along the slide groove; the shovel blade is welded to the front end of the bucket body bottom, and the breaker knife is welded to the shovel blade; the support mechanism is used to control the lifting and lowering of the sliding baffle and the rotating baffle. When the scraper is shoveling and transporting ore in the underground mine pile, collisions will occur between the bucket's limit block and the scraper's boom and cylinder.
