The fan 302 draws external air and flows out through the ventilation pipe 301 to complete the ventilation. At the same time, the mine dust enters the ventilation pipe 301 with the air, and the filter plate 303 filters the circulating air to filter out the mine dust. When a certain amount of mine dust is filtered out, the No. 3 electric telescopic rod 305 is started, and the No. 3 electric telescopic rod 305 drives the scraper 306 to rise and fall to scrape the mine dust on one side of the filter plate 303 into the collection box 304.
