The first crushing roller 7 and the second crushing roller 8 are located on the inner side of the crushing box 1, and the first crushing roller 7 and the second crushing roller 8 rotate relative to each other.

[0028] In this embodiment, the first crushing roller 7 is driven to rotate by the first motor 11, and the second crushing roller 8 is driven to rotate by the second motor 12, so that the first crushing roller 7 and the second crushing roller 8 can be driven to rotate relative to each other to crush the construction waste.

[0029] The dust collection mechanism also includes a dust collection box 9, a sealing door 13 is arranged on the outer side of the dust collection box 9, an exhaust fan 14 is fixedly installed on the top of the dust collection box 9, an exhaust head 10 is fixedly installed on the bottom of the exhaust fan 14, an exhaust pipe 15 is fixedly installed on the right side of the exhaust fan 14, and a first dust collection pipe 52 and a second dust collection pipe 62 are fixedly installed on the top of the dust collection box 9, respectively. The first dust collection pipe 52 is fixedly connected to the upper dust collection box 5, and the second dust collection pipe 62 is fixedly connected to the lower dust collection box 6.

[0030] In this embodiment, negative pressure can be drawn into the dust box 9 by starting the exhaust fan 14, so that the first dust suction pipe 52 draws air from the upper dust box 5 to suck the dust that drifts to the feed nozzle 3, and the second dust suction pipe 62 draws air from the lower dust box 6 to suck the dust that drifts to the discharge nozzle 4. The dust sucked into the dust box 9 is filtered through the exhaust head 10, and then the gas is discharged to the outside through the exhaust pipe 15.

[0031] The upper dust extraction box 5 has a first filter plate 51 for filtering large particles on one side close to the crushing box 1 , and the lower dust extraction box 6 has a second filter plate 61 for filtering large particles on one side close to the crushing box 1 .

[0032] In this embodiment, the first filter plate 51 can be used to filter large particles of garbage, and the second filter plate 61 can be used to filter large particles of garbage.

The top of the dust box 9 is slidably sleeved with a movable column 17, and the bottom end of the movable column 17 is fixedly installed with the cleaning ring 20; the outer side of the movable column 17 is sleeved with a return spring 18, and the return spring 18 is located above the dust box 9, and the top of the movable column 17 is fixedly installed with a handle 19; the inner top wall of the dust box 9 is fixedly installed with two fixed columns 16, and the fixed column 16 and the cleaning ring 20 are slidably installed.

[0034] In this embodiment, after vacuuming for a period of time, the staff presses the handle 19 to drive the movable column 17 to slide downward along the dust box 9 through the handle 19, and drives the cleaning ring 20 to slide downward along the fixed column 16 through the movable column 17, so that the bristles 21 clean the dust on the outside of the vacuum head 10. Under the elastic action of the reset spring 18, the cleaning ring 20 can be reset, so that the vacuum head 10 can be cleaned reciprocally.

[0035] Working principle: When in use, the construction waste to be crushed is thrown into the crushing box 1 through the feed nozzle 3, the first crushing roller 7 is driven to rotate by the first motor 11, and the second crushing roller 8 is driven to rotate by the second motor 12, which can drive the first crushing roller 7 and the second crushing roller 8 to rotate relative to each other to crush the construction waste. The dust generated in the crushing process will float out through the feed nozzle 3 and the discharge nozzle 4. By starting the exhaust fan 14, the vacuum box 9 can be evacuated with negative pressure, so that the first dust suction pipe 52 exhausts the upper dust suction box 5, so that the first filter plate 51 filters the large particles and then absorbs the dust scattered to the feed nozzle 3, and the second dust suction pipe 62 exhausts the lower dust suction box 6. The second filter plate 61 is exhausted to filter large particles and then the dust scattered to the discharge nozzle 4 is sucked. The dust entering the dust box 9 is filtered through the suction head 10, and then the gas is discharged to the outside through the exhaust pipe 15. The dust is purified and processed in the dust box 9, thereby reducing the dust generated by the crushing of construction waste by this device, and the reduction effect is good. The crushed materials are discharged through the discharge nozzle 4, which is convenient for the recycling of the crushed construction waste. By pressing the handle 19, the movable column 17 and the cleaning ring 20 are driven to move downward, so that the cleaning ring 20 drives the bristles 21 to clean the dust on the outside of the suction head 10, and then the dust and garbage in the dust box 9 can be cleaned by opening the sealing door 13.
