The aperture of the dust cover 30 of the present embodiment gradually increases from the direction away from the lower material body 10, so as to meet the use requirement of the material from the lower portion of the lower material body 10 to the truck hopper. Of course, it should be noted that the material in the lower material body 10 is not limited to coke, and the material arranged below the lower material body 10 is not limited to be discharged to a truck hopper, and it is obvious to those skilled in the art that the material may be other solid materials with certain small particles, and the material may also be arranged below the lower material body to other positions, accordingly, the caliber of the dust cover 30 is not limited to that shown in the figure, and the caliber of the dust cover 30 may be equal, gradually smaller, or other irregular shapes towards the direction away from the lower material body 10, and will not be described herein.

Specifically, the dust cover 30 of the present embodiment includes a plurality of supporting frames 31 arranged at intervals, and dust covers 32 are respectively connected between two adjacent supporting frames 31; in the dust cover 30 of the present embodiment, the pulley attachment bracket 41 is connected to the support frame 31 located at the cover opening position, and the pulley 40 is rotatably connected to the pulley attachment bracket 41, thereby attaching the pulley 40 to the dust cover 30.
