[0036] As shown, Figure 4As shown, the conveyor 1 includes a pair of bases 101. Multiple dust suppression mechanisms 102 are installed on the side walls of the pair of bases 101. When the coal falls above the bases 101 and continues to be conveyed forward, a small amount of dust will still be generated. At this time, the dust suppression mechanism 102 can be turned on to spray water mist onto the coal, thereby effectively reducing the diffusion of dust particles and ensuring that the environment is not damaged and the safety of human beings is guaranteed.

[0037] like Figures 1-6 As shown, the cutting mechanism 4 includes a blade holder 403 and multiple sets of support rods 401.
