[0022] The personnel can push the mobile box 1 to move, move the mobile box 1 to a suitable position, and then turn on the dust suction fan 301 to vacuum the inside of the coal mine tunnel. During the vacuuming process, the light receiver 310 cannot receive the signal of the light transmitter 309 due to the dust blocking the light. At this time, the water pump 311 is turned on to draw water from the bottom of the mobile box 1 and spray it from the nozzle 313 to reduce the dust sucked into the guide frame 302, so that the dust enters the collection frame 303, collects the dust, and realizes the dust removal process inside the coal mine tunnel.

In addition, the barrier of the barrier net 410 can prevent the dust from directly contacting the dust suction fan 301 and causing damage to the dust suction fan 301. When the coal mine tunnel collapses, the collapse above the equipment will fall to the top of the adjustment frame 610, and the adjustment frame 610 will be pressed to compress the spring telescopic rod 609. The movement of the adjustment frame 610 drives the closing frame 612 and the push plate 613 to move.
