[0002] In the current technology, a large amount of construction waste is generated during the construction process, such as concrete blocks, bricks, tiles, wood, metal, plastic, gypsum board, etc. Due to the physical characteristics of these construction wastes, if not properly managed, they will not only occupy land, but also cause dust pollution. At present, construction workers generally use crushers to crush construction waste and then process it in a unified manner. However, this method of processing has the problems of dust pollution during the crushing process and the dust being easily inhaled by construction workers, affecting their health.

[0003] There is still a lack of better technical solutions to the problems of dust pollution caused by existing crushers and the health risks of workers inhaling dust during crushing. Utility Model Content
