A crushing component is installed inside the casing 1 to perform coarse crushing of the construction waste. A frame-shaped water pipe 9 is fixedly connected to the top of the inner wall of the casing 1. Several atomizing nozzles 10 are fixedly connected to both sides of the frame-shaped water pipe 9 to spray water in atomized form, which plays a role in dust suppression. A dust collection component is installed on one side of the top of the casing 1 to absorb dust. A bottom cylinder 16 is fixedly connected to the bottom of the casing 1. A crushing component is installed inside the bottom cylinder 16 for further crushing of the construction waste. Several screen holes 20 are opened at the bottom of the bottom cylinder 16. Construction waste crushed to a specified particle size will pass through the screen holes 20 and be discharged from the machine.

[0033] Reference Figure 1 and Figure 4 The dust collection assembly includes a dust collection box 12, a suction head 13, a fan 14, and a filter 15. The dust collection box 12 is fixedly connected to one side of the top of the housing 1 and is used to collect and store dust. The suction head 13 is fixedly connected to the front of the dust collection box 12 to facilitate the concentrated suction of dust. The fan 14 is fixedly installed on the back of the dust collection box 12, and the input end of the fan 14 is connected to the inside of the dust collection box 12. After the fan 14 is started, it can suck the dust into the dust collection box 12. The filter 15 is snapped into one side of the inside of the dust collection box 12 to filter the dust in the suction air and avoid harming human and environmental health.

[0034] Reference Figure 3 The crushing assembly includes two crushing rollers 3, a motor 4, and a transmission assembly. The two crushing rollers 3 are rotatably connected to both sides inside the housing 1 via bearings. When the two crushing rollers 3 rotate in opposite directions, the teeth on their surfaces can crush construction waste into small pieces. A transmission assembly is installed in the middle of one side of the housing 1, and a motor 4 is fixedly installed at one end of the other side of the housing 1. The output end of the motor 4 is fixedly connected to the end of one of the crushing rollers 3, which serves as a drive to rotate the crushing roller 3.

[0035] Reference Figure 3The transmission assembly includes two gears 5 and two gears 6. One end of each of the two crushing rollers 3 passes through the outer wall of the housing 1 and is fixedly connected to gear 5. Two gears 6 are rotatably connected to the middle of one side of the housing 1 through bearings. Gears 5 and gears 6 mesh with each other and play a transmission role, so that when one crushing roller 3 is driven to rotate, it can drive the other crushing roller 3 to rotate through gears 5 and gears 6.

[0036] Reference Figure 1 and Figure 5 The crushing assembly includes a second motor 17, a drive shaft 18, and several blades 19. The bottom cylinder 16 is fixedly connected to the bottom end of the housing 1. The construction waste, after being coarsely processed by the crushing roller 3, falls into the bottom cylinder 16. The drive shaft 18 is rotatably connected to the inner wall of the bottom cylinder 16 through bearings. Several blades 19 are fixedly connected to the surface of the drive shaft 18 in a cross shape. The second motor 17 is fixedly installed at one end of the bottom cylinder 16, and the output end of the second motor 17 is fixedly connected to the end of the drive shaft 18. The second motor 17 drives the several blades 19 on the surface of the drive shaft 18 to rotate at high speed, which can further crush the construction waste.

[0037] Reference Figure 1 Both sides of the bottom of the casing 1 are fixedly connected to brackets 7, which support and raise the crusher to facilitate material feeding.

[0038] Reference Figure 3 A protective shell 8 is fixedly connected to one side of the housing 1, and the transmission component is located inside the protective shell 8. The protective shell 8 protects the gears on the transmission component and prevents foreign objects from causing the gear structure to jam.

[0039] Reference Figure 1 and Figure 2 A water inlet connector 11 is fixedly connected to the top of one side of the casing 1, and one end of the water inlet connector 11 is connected to the inside of the frame-shaped water pipe 9. By connecting the water inlet connector 11 to the water supply pipe, spray water can be input into the frame-shaped water pipe 9 inside the crusher.

[0040] Reference Figure 1 Each of the four corners of the top of the casing 1 is fixedly connected with a lifting ring 21. The lifting ring 21 allows the crusher to be lifted and moved, making it easy to relocate.

[0041] Working principle: Construction waste to be processed is fed into the machine casing 1 through the feeding nozzle 2. The starting motor 4 drives one of the crushing rollers 3 to rotate. Simultaneously, with the cooperation of gears 6 and 5, the other crushing roller 3 rotates in the opposite direction. As the construction waste falls through, the teeth on the crushing roller 3 break it into small pieces for subsequent processing and transportation. The construction waste, after coarse processing by the crushing roller 3, falls into the bottom cylinder 16. The starting motor 17 in the crushing assembly drives several blades 19 on the surface of the drive shaft 18 to rotate at high speed, further crushing the construction waste. Multiple screen holes 20 are set below the bottom cylinder 16. When the construction waste is... Only when the material is crushed to the required particle size will it pass through the sieve hole 20 and be discharged. Thus, the crusher can crush construction waste to the specified particle size. It is easy to use. The water inlet connector 11 is connected to an external water supply pipe. During the crushing of construction waste, spray water is introduced into the frame-shaped water pipe 9 inside the crusher and sprayed out in atomized form from several atomizing nozzles 10. This can reduce the dust generated during the crushing process. A small amount of overflowing dust will be sucked into the dust collection box 12 by the fan 14 and collected and stored in the dust collection box 12 under the protection of the filter screen 15. Therefore, the crusher has a better dust removal effect during the crushing of construction waste and avoids negative impacts on human health and the environment.
