Dedusting device for stone machining

The invention discloses a dedusting device for stone machining. The dedusting device for stone machining comprises a worktable. A conveyor belt and a water storage pond are separately arranged at theupper and lower ends of the worktable, a stone to dedusted is placed on the conveyor belt, and the conveyor belt, the worktable and the water storage pond are of penetrating structures; a dedusting mechanism is arranged above the conveyor belt; the dedusting device for stone machining clean dust on the surface of the stone comprehensively as hairbrushes on two sides reciprocate. Moreover, a sprayhead is arranged above the conveyor belt to clean the stone, water cleaning the stone can flow back to the water storage pond through the conveyor belt and the worktable, and a filter screen in the water storage pond filters solid state impurities in the flowback water, so that the flowback water can be recycled, and therefore, waste of a water resource is reduced. In addition, water in the waterstorage pond is replaced co
