Usually, drilling operations are required before installing the anchor rods, and the drilling equipment will generate a large amount of dust and mud during the operation. The impurities in the borehole are discharged by an air pump, and the raised dust will seriously reduce the air quality of the construction environment.

The filter element 6 has a plurality of filter elements, each of which is provided with a filter element 6. The filter element 6 has a plurality of filter elements, each of which is provided with a filter element 6.

[0025] Among them, a dust suction cylinder 7 is provided on the side of the dust reduction body 1 away from the drilling position 2, and a dust suction chamber 70 is provided in the dust suction cylinder 7. The dust suction chamber 70 is connected with the mud collecting chamber 3, and the drill rod 21 passes through the dust suction chamber 70.

A dust collecting box 9 is installed at the air outlet end of the fan 8, and a dust filter 10 is installed on the dust collecting box 9.

[0026] Specifically, in order to further improve the dust reduction effect of the drilling dust reduction device, after the mud or dust initially filtered by the mud collecting chamber 3 enters the dust suction chamber 70, it will be pulled and moved by the negative pressure generated by the fan 8 when it is working, so that the mud or dust passes through the dust suction cylinder 7 and the fan 8 into the dust collecting box 9, thereby achieving a better dust reduction purpose.

[0027] Among them, the outer surface of the dust suction chamber 70 is provided with a vent tube 73, and a plurality of vents are arranged on the vent tube 73, the outer surface of the vent tube 73 is provided with a dust ring chamber 74, and one side of the dust ring chamber 74 is provided with a connecting port 71 connected thereto, and the connecting port 71 is connected to the dust exhaust pipe 72.

When the torsion spring is in a non-stressed state, the movable baffle 20 is vertically arranged with the cavity wall of the through cavity 19. The movable baffle 20 can also be used to effectively intercept dust or mud residue flowing out of the mud collecting chamber 3. By using the reset effect of the torsion spring, when the movable baffle 20 is reset, the mud residue can be slapped toward the mud collecting chamber 3, thereby further improving its interception effect.

[0030] A power supply battery 11 is provided in the dust suppression body 1, and the power supply battery 11 is electrically connected to the fan 8. By utilizing the power supply battery 11, the flexibility of the use area of ​​the device can be effectively improved.
