[0002] At present, in the construction survey stage, advance drilling rigs are usually used to find out whether there are abnormal geological phenomena within a certain range below the foundation. Advance drilling rigs are a type of drilling equipment used for underground pipeline construction, consisting of drill rods, sliding brackets, turntables, gear transmission systems, hydraulic systems, electrical control systems, etc. In the process of drilling holes through drill rods, in order to reduce the flying of dust, dust suction-type auxiliary dust reduction devices are usually used.

[0003] However, although the traditional auxiliary dust reduction device can separate dust from air through the dust filter when in use, after long-term use, the surface of the dust filter is easily covered with a large amount of debris, so the staff needs to clean the surface of the dust filter regularly (if not cleaned, it will affect the dust suction effect of the auxiliary dust reduction device). When cleaning the surface of the dust filter, not only does it need to be stopped for cleaning, but it also needs to be disassembled and cleaned with tools, thereby reducing the convenience of maintaining the auxiliary dust reduction device.

Through the setting of this auxiliary dust reduction device, the dust flying rate during the drilling process of the drill rod 3 can be effectively reduced.

[0038] When it is necessary to clean the debris covered on the surface of the dust filter 109 (it can be cleaned regularly), it is only necessary to start the small motor 507 through the controller 4, and then the first bevel gear 509 on the rotating shaft of the small motor 507 drives the second bevel gear 5010, the transmission rod 505 and the transmission disk 506 to rotate, and then the transmission disk 506 drives the toggle column 508 to rotate, and the toggle column 508 drives the driving frame 504, the fixed plate 503 and the three cleaning brushes 502 to move back and forth, and then the three cleaning brushes 502 that move back and forth are used to clean the debris covered on the surface of the dust filter 109, thereby avoiding affecting the dust suction effect of the auxiliary dust reduction device, and during the cleaning process, there is no need to stop the machine for cleaning, and there is no need to manually disassemble and clean with tools, thereby improving the convenience of maintenance of the auxiliary dust reduction device.

[0039] When cleaning the debris covered on the surface of the dust filter 109, the staff can also directly manually rotate the rotating disk 601 to make the rotating disk 601 rotate with the manual rotating rod 6, the third bevel gear 602, the second bevel gear 5010, the transmission rod 505 and the transmission disk 506, and then rotate the toggle column 508 through the transmission disk 506, and the toggle column 508 drives the driving frame 504, the fixed plate 503 and the three cleaning brushes 502 to move back and forth, so that the debris covered on the surface of the dust filter 109 can also be cleaned up.
