[0021] like Figure 1 As shown, the drive assembly 8 includes a motor bracket 13, a driving gear 14, a synchronous gear 15, a synchronous gear 2 16 and a driving motor 17. The motor bracket 13 is fixed to the outside of the grinder housing 1, and the driving gear 14 is rotatably arranged between the motor bracket 13 and the grinder housing 1. The synchronous gear 15 and the synchronous gear 2 16 are arranged on the upper and lower sides of the driving gear 14. The synchronous gear 15 and the synchronous gear 2 16 are both engaged with the driving gear 14. The synchronous gear 15 is connected to the coarse crushing roller 5, and the synchronous gear 2 16 is connected to the fine crushing roller 7. The driving motor 17 is fixed to the outside of the motor bracket 13, and the output end of the driving motor 17 is connected to the driving gear 14.

[0022] like Figure 2 As shown, the coarse crushing roller 5 is provided with a transmission gear 18 at one end away from the drive assembly 8, and the two coarse crushing rollers 5 are provided with a transmission gear 18 at one end, and the two transmission gears 18 are meshed with each other.

[0023] like Figure 1 and Figure 3As shown, a discharge port 20 is provided on the lower side wall of the crusher shell 1, and a discharge bracket 21 is fixedly provided on the outside of the discharge port 20. The discharge bracket 21 is fixedly connected to the crusher shell 1, and a discharge conveyor belt 22 is rotatably arranged inside the discharge bracket 21. One end of the discharge conveyor belt 22 is arranged in the end of the crusher shell 1 away from the discharge port 20, and the discharge conveyor belt 22 is arranged in a hollow shape.

[0024] like Figure 3 and Figure 5 As shown, a baffle 23 is fixedly provided above the crusher shell 1, and the baffle 23 is provided on the side of the water pipe 10 close to the feed port 2. Support legs 24 are symmetrically provided below both ends of the discharging bracket 21, and a cleaning roller brush 25 is provided between the support legs 24.

[0025] A drainage valve pipe 26 is provided on the outer side of the lower end of the pulverizer shell 1 , and the drainage valve pipe 26 is provided below the discharge conveyor belt 22 .

[0026] During specific use, construction waste is put into the crusher shell 1 from the feed port 2, and the construction waste falls on the two coarse crushing rollers 5. The drive motor 17 is started, and the drive motor 17 drives the drive gear 14 to rotate. The drive gear 14 drives the synchronous gear 1 15 and the synchronous gear 2 16 to rotate, so that the synchronous gear 1 15 drives a coarse crushing roller 5 to rotate, and the two coarse crushing rollers 5 are rotated inward at the same time through the transmission gear 1 18, thereby squeezing and crushing the construction waste. Then the crushed construction waste falls onto the two fine crushing rollers 7 along the guide inclined plate 6, and at the same time, the synchronous gear 2 16 drives a fine crushing roller 7 to rotate, and the two fine crushing rollers 7 are rotated inward at the same time through the transmission gear 2 19, thereby crushing the crushed construction waste again, crushing the construction waste multiple times, and improving the crushing efficiency. The construction waste that has been crushed twice falls onto the discharge conveyor belt 22, and the rotating discharge conveyor belt 22 transports the multiple crushed construction waste out from the discharge port 20.

[0027] While crushing, the cleaning water pump 11 draws water from the water tank 9, and the water flows along the cleaning water pipe 12 to the water spray pipe 10. The nozzle below the water spray pipe 10 sprays the water into the crusher shell 1, and the water is used to wet the surface of the construction waste to prevent dust from being generated when crushing the construction waste, avoiding dust pollution to the environment, and also preventing the operator from inhaling dust and damaging the body.

[0028] Wetting construction waste will inevitably produce sewage, which falls onto the discharge conveyor belt 22. The sewage passes through the hollow discharge conveyor belt 22 and falls into the lower end of the crusher shell 1. Some sludge in the sewage will block the hollow discharge conveyor belt 22. When the blocked discharge conveyor belt 22 rotates to the bottom, the cleaning roller brush 25 cleans the blocked discharge conveyor belt 22, and the drain valve pipe 26 is opened to discharge the sewage out of the crusher shell 1.
