[0022] Figure 1-4The utility model shows a construction waste crusher of an embodiment, comprising a crushing box 1, the inner cavity of the crushing box 1 is fixedly connected with a discharge plate 13, the front end of the discharge plate 13 penetrates to the front side of the crushing box 1, a water pump 9 is fixedly installed at the bottom of the left side of the crushing box 1, a fixed water pipe 11 is fixedly connected to the bottom of the front side of the crushing box 1, and a plurality of atomizing nozzles 12 connected thereto are fixedly connected to the surface of the fixed water pipe 11, the water outlet end of the water pump 9 is connected with a water supply pipe 10, and the end of the water supply pipe 10 away from the water pump 9 is connected to the fixed water pipe 11, through the water pump 9, the water supply pipe 10 is connected to the fixed water pipe 11, and the water supply pipe 10 is connected to the fixed water pipe 11. The water pipe 10 and the atomizing nozzle 12 are used in combination to atomize and reduce dust on the construction waste crushed by the self-unloading plate 13, thereby preventing a large amount of dust from being generated at the construction waste discharge position. The inner cavity of the crushing box 1 is rotatably connected to two crushing rollers 2. A DC motor 3 is fixedly installed at the left end of the front side of the crushing box 1. The front end of the crushing roller 2 on the left side penetrates the outside of the crushing box 1 and is fixedly connected to the output shaft of the DC motor 3. The rear ends of the two crushing rollers 2 penetrate the rear side of the crushing box 1 and are fixedly connected to the synchronous gear 4. The two synchronous gears 4 are meshed with each other. A feeding box 5 is fixedly connected to the top of the crushing box 1, and rotating rods 6 are rotatably connected to both sides of the inner cavity of the feeding box 5. A sealing plate 7 is fixedly connected to the surface of the rotating rod 6. A propulsion assembly 8 is arranged on the front side of the crushing roller 2. The propulsion assembly 8 includes a Z-shaped plate 81 located on the front side of the feeding box 5. Two limiting guide rails 82 are fixedly connected to the front side of the feeding box 5. The Z-shaped plate 81 is slidably connected to the surface of the limiting guide rail 82. An electric telescopic rod 83 is fixedly installed on the front side of the feeding box 5. The output end of the electric telescopic rod 83 is fixedly connected to the Z-shaped plate 81. Racks 84 are fixedly connected at both ends. The front end of the rotating rod 6 passes through the front side of the feeding box 5 and is fixedly connected to a gear 85. The gear 85 is meshed with the rack 84. Through the setting of the propulsion component 8, the coordinated use of the Z-shaped plate 81 and the electric telescopic rod 83 has a propulsive effect on the rack 84.

[0023] Working principle: When the utility model is used, the user turns on the DC motor 3, and under the meshing action of the two synchronous gears 4, the two crushing rollers 2 rotate in the inner cavity of the crushing box 1, and then turns on the electric telescopic rod 83, which pushes the Z-shaped plate 81 to the left, and the Z-shaped plate 81 drives the two racks 84 to slide. Under the meshing action of the racks 84 and the gears 85, the two rotating rods 6 rotate and drive the sealing plate 7 to rotate in the inner cavity of the feeding box 5. At this time, the top of the feeding box 5 is opened to feed materials into its inner cavity. After feeding, After completion, the electric telescopic rod 83 drives the Z-shaped plate 81 to reset, so that the rack 84 drives the gear 85 to rotate, and then the sealing plate 7 rotates and resets to seal the top of the feeding box 5, thereby preventing gravel from splashing and dust from flying out. The construction waste falls into the inner cavity of the discharge plate 13 under the crushing action of the crushing roller 2, and is discharged from the inner cavity of the crushing box 1. When discharged to the front side of the crushing box 1, the water pump 9 draws water from the source and transports it to the inner cavity of the fixed water pipe 11 through the water supply pipe 10, and the atomizing nozzle 12 sprays the water into atomized form to atomize and reduce dust on the crushed material.

[0024] In summary: the construction waste crusher crushes the construction waste through the coordinated use of the crushing box 1, the crushing roller 2 and the DC motor 3, and seals the top of the feeding box 5 by the coordinated use of the sealing plate 7 and the propulsion assembly 8 to prevent the crushed stones and dust from splashing out. At the same time, the water pump 9 and the atomizing nozzle 12 are used in coordination to atomize the crushed construction waste to reduce dust, thereby achieving the purpose of effectively suppressing the generation of dust and preventing the splashing of crushed stones.
