[0002] In the process of coal mining, the mining machine can increase the excavation progress by more than 30 times compared with the excavation process of drilling and blasting. The high mining efficiency of the mining machine will lead to high dust concentration in the air of the mining face in the mine. In the mild case, it will be inhaled by miners and affect their health. In the severe case, the dust concentration is too high and a dust explosion will occur, affecting the life safety of mine workers.

[0003] The excavator itself is equipped with a ventilation and dust removal system, which can extract the dust and harmful gases generated when the excavator is working, ensuring the safety of the working environment of the excavator and the workers. A kind of excavator with application number 2013101237151 is a kind of excavator, which sets the nozzle on the cutting part, and can directly settle the dust generated by the excavator, but when the dust settles, a small amount of dust will still float to various corners of the excavator; a kind of visualization test device and method for studying the dust migration law in the complex environment of the excavation face tunnel with application number 201510424182X, its main purpose is to transfer and settle the generated dust, but the dust around the body of the excavator will inevitably be deposited and not easy to clean in time.

The red laser head 32 is arranged in the straight line direction of the plurality of collecting grooves 9. The dust in the collecting groove 9 flies up, and the red light of the red laser head 32 passes through the dust. The visual sensor 31 collects the laser irradiation process. If the laser is very dark and narrow, it means that the amount of dust is small.If the laser is very bright and wide, there will be a lot of dust. A rubber ball 20 is arranged in the lower part of the third installation cavity 30. The top of the rubber ball 20 is connected to multiple jet ducts 17.
