[0025] Embodiment 2

[0026] See also Figure 1-4 An electric push rod 17 is fixedly installed inside the base 1, and a top plate 18 is installed at the output end of the electric push rod 17. A scraper B19 is fixedly installed on the surface of the top plate 18. The scraper B19 is slidably connected to the base 1, and a soft pad 20 is fixedly installed on the surface of the scraper B19.

[0027] Working principle: When using the dust removal device, first turn on the water pump 6. The water pump 6 will inject the water in the water tank 4 into the annular pipe 7 and the long rod 9 through the connecting pipe 5, and then inject it into the interior of the dust removal box 2 through the nozzle A8 and the nozzle B10. At this time, the dust is transported to the dust removal box 2 through the dust conveying pipe 3.

When it is necessary to clean the surface of the base 1, it is only necessary to open the electric push rod 17, and the electric push rod 17 will drive the top plate 18 to move, and the top plate 18 will drive the scraper B19 and the soft pad 20 to slide on the surface of the base 1 until the mud on the base 1 is scraped to the drain pipe 16 and discharged from the surface of the base 1. The design of the scraper B19 has the effect of scraping the sewage on the surface of the base 1 to the drain pipe 16, thereby avoiding the corrosion of the base 1 due to the residual sewage on the surface of the base 1 and also preventing the scraper B19 from being bumped against the inner surface of the dust removal box 2.
