A dustproof net 8 for dust prevention is fixedly installed on the Y-shaped tee pipe 7. A fan 9 for air supply is fixedly installed inside the Y-shaped tee pipe 7. An atomizer 11 for dust suppression is fixedly installed inside the Y-shaped tee pipe 7. The opening at the top of the Y-shaped tee pipe 7 is located directly below the motor 3. A water storage tank 12 for water storage is fixedly installed on the cutting workbench 1.

[0032] The water tank 12 is equipped with a water pump 13 for delivering water. A water supply pipe 14 is connected between the water pump 13 and the atomizer 11. The water tank 12 is equipped with a scale window 15 for observing the liquid level. A dust collection box 16 for collecting dust is fixedly installed at the bottom of the cutting workbench 1. The water tank 12 is provided with a liquid injection port for adding water.

[0033] Cutting workbench 1: Serves as the basic support structure for the entire equipment, providing support for the cutting operation;

[0034] Rotary arm 2: Used to raise and lower the cutting disc 4 to adjust the cutting height;

[0035] Motor 3: Drives the cutting disc 4 to rotate at high speed to achieve the cutting function;

[0036] Cutting disc 4: Performs cutting operations under the drive of motor 3;

[0037] Protective cover 5: Provides protection to prevent accidental injury during the cutting process;

[0038] Rubber dust cover 6: It is elastic and fits as closely as possible to the object being cut to prevent dust from spreading.

[0039] Y-shaped tee pipe 7: Includes vertical and angled pipes, which generate negative pressure through airflow inside the pipes to suck up dust and guide it out;

[0040] Dustproof net 8: Used to prevent dust from entering along the vertical pipe of the Y-shaped tee 7;

[0041] Fan 9: Accelerates the airflow in the vertical duct, generates negative pressure, and blows away dust;

[0042] Atomizer 11: Atomizes water to mix with dust and achieve dust suppression;

[0043] Water storage tank 12: store water for dust suppression;

[0046] Scale window 15: observe the liquid level in the water storage tank 12 to determine whether water needs to be added;

[0047] Dust collection box 16: collect settled dust.

[0048] Working principle:

[0049] First, in use, the motor 3 will drive the cutting disc 4 to rotate at high speed for cutting, and the rotating arm 2 can move the cutting disc 4 downward to contact the object to be cut. In this process, the rubber dust removal sleeve 6 will first contact the object to be cut. Because the rubber dust removal sleeve 6 has a certain elasticity, the rubber dust removal sleeve 6 will try to adhere to the object to be cut as much as possible, so as to avoid the dust generated by cutting from diffusing in the air. Then the fan 9 starts, which will speed up the air flow in the vertical pipe of the Y-shaped tee pipe 7. When the air flow in the vertical pipe becomes fast, the pressure will also decrease, thereby generating negative pressure (i.e. suction) in the inclined pipe of the Y-shaped tee pipe 7.

[0050] Second, the dust generated by cutting will enter the inside of the Y-shaped tee pipe 7 under the action of gravity and the suction of the Y-shaped tee pipe 7, and then be discharged to the dust collection box 16 under the blowing of the fan 9. In this process, the water pump 13 will pump the water in the water storage tank 12 into the atomizer 11 through the water pipe 14. The atomizer 11 will atomize the water, which will mix with the dust in the Y-shaped tee pipe 7. The adhesion between the wet dust particles will increase and gather together, and the weight of the dust will increase, thereby reducing its suspension ability in the air, accelerating the settlement of the dust, so that the dust will not be raised again when entering the dust collection box 16.

[0051] Finally, it should be noted that: obviously, the above embodiments are only examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the implementation. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
