The motor 4 is turned on to rotate the pulley 1 5 and the pulley 2 6, and at the same time drive the U-shaped sliding plate 3 to slide left and right. When the U-shaped sliding plate 3 moves, it will contact the track surface of the I-shaped steel rail 2 through the ash plate 304, and the friction dust or tiny particles generated by the friction between the pulley 1 5, the pulley 2 6 and the I-shaped steel rail 2 are collected into the collecting groove 305. The dustproof component also includes an accordion cover 306 and a fixing plate 307. The accordion cover 306 is installed on the U-shaped The left and right sides of the sliding plate 3 and the top of the accordion cover 306 are slidably connected to the mounting plate 1, and the I-shaped rail 2 can be dust-proofed by the accordion cover 306. Fixed plates 307 are provided on the left and right sides of the bottom of the mounting plate 1. The four corners of the fixed plate 307 are threadedly connected with bolts 309, and the bolts 309 penetrate the accordion cover 306 and are threadedly connected. A feed trough 310 is penetrated and opened on the left and right sides of the middle of the fixed plate 307 on one side. The top of the feed trough 310 on one side is rotatably connected with a baffle 311. The left and right sides of the baffle 311 are fixedly connected with spring connecting plates 314.
