[0021] Note: The length, width and height of the dust collecting box 5 are 2000 mm, 2000 mm and 5000 mm respectively.
[0022] Further improvement, such as Figure 4 As shown, the water tank 8 is located at the bottom of the dust collecting box 5 and a return pipe 15 is connected therebetween. A valve 16 is installed on the return pipe 15, and a filter screen 17 is built into the return pipe 15, which can filter and recycle the water used for spraying and dust reduction.
