The displacement block contacts the pushing block to open the air extraction pipe. At this time, the blower is started, and the gas enters the detection box through the air extraction port and the air extraction pipe, and then is discharged through the exhaust pipe. At this time, the laser gas analysis device detects the gas in the detection box. After the detection of the gas at one air extraction port position is completed, the displacement block is moved above the next air extraction pipe, and the next air extraction pipe is opened to extract new gas into the detection box for detection operation. This design can facilitate the sampling and detection operation of gases at multiple points underground in the mine.

The displacement block contacts the displacement frame, pushing the displacement frame to displace. The rotating block rotates to drive the convex block to perform circular displacement. The displacement of the convex block intermittently contacts the mounting plate, pushing the mounting plate to displace and vibrate. The mounting plate rotates to drive the filter plate to vibrate, and the dust adhering to the filter plate falls due to vibration and enters the collection box for collection operation. This design can prevent the dust in the air from affecting the detection of the laser gas analysis device. BRIEF DESCRIPTION OF THE DRAWINGS
