In this embodiment, a closed space is formed by the arrangement of the shell 21, the frame 11 and the scraper frame 12, so that the material will not be scattered during the conveying process, and dust is prevented from being generated. At the same time, the arrangement of the shell 21 collects the dust generated by the material in the dust cover to prevent it from spreading everywhere. The two ends of the shell 21 are closed by the arrangement of the dust curtain 27 to prevent dust from being discharged from the two ends of the shell 21. The worm 23 is driven to rotate by rotating the rotating handle 24, and the worm gear 25 is driven to rotate by the meshing of the worm 23. The dust curtain 27 is rolled up or released by the winding drum 26 driven by the worm gear 25. The height of the closure of the two ends of the shell 21 is adjusted according to the amount of conveyed material, so that dust can be prevented without affecting the conveying of the material. One end of the dust curtain 27 is counterweighted by the arrangement of the counterweight rod 30, and the dust curtain 27 is straightened to facilitate the closing of the shell 21 and prevent the dust curtain 27 from floating.
