The user installs the assembled first rotating column 15 along the first threaded rod 14 installed at the upper end into the threaded hole 13 opened in the first connecting block 12 at the lower end of the dust removal box body 1. After the first threaded rod 14 and the threaded hole 13 are installed, the first rotating column 15 and the dust removal box body 1 are assembled. At this time, the lower ends of the other three first connecting blocks 12 are all installed with the first rotating column 15.

[0033] In the second step, after the user assembles the first rotating column 15, the user installs the fixing plate 31 inside the first groove 3 opened above the dust removal box body 1, and installs the fixing plate 31 along one side of the inner wall of the first groove 3. After the installation is completed, the user picks up the two blocking bars 33 and installs the two blocking bars 33 along the other inner wall of the first groove 3. After the user installs the blocking bars 33, the user picks up the partition box 36 and installs it above the fixing plate 31 and the blocking bars 33. After the installation is completed, the partition box 36 is partially assembled. After the user assembles the partition box 36, the user picks up the motor 4 and installs the motor 4 into the third groove 37 opened above the partition box 36. After the user fixes the motor 4, the user picks up the first rotating rod 41 and installs the first rotating rod 41 to the side end of the motor 4 to connect it. After completion, the user installs the first rotating gear 42 on the circumferential surface of the first rotating rod 41. After assembling the first rotating gear 42, the user picks up the second rotating rod 43, installs the second rotating gear 44 on the circumferential surface of the second rotating rod 43, and installs the assembled second rotating rod 43 into the third hole 38 opened inside the third groove 37.

After taking them out, the user picks up the water pipe to fill water into the first groove 3, and at this time pushes the pushing bar 35, which will drive the blocking block 34 to slide to one side. At this time, the connection between the first groove 3 and the fifth groove 66 will be blocked. Under the cooperation of the blocking block 34, the blocking bar 33, the fixing plate 31 and the partition box 36, a closed space will be formed to store water. When the water in the space is full, the user picks up the handle block 64 and puts it back into the seventh hole 61. After it is installed, the user pushes the pushing handle 11. At this time, under the action of the rotating shaft 25, the rubber protective ring 26, the second threaded rod 21, the pulley fixing block 16 and the first connecting block 12, the dust removal box 1 will move. When the device moves to the position where dust removal is required When the user turns on the switch to start the motor 4, the motor 4 will drive the first rotating rod 41 to rotate. The rotation of the first rotating rod 41 will drive the first rotating gear 42 to rotate. The rotation of the first rotating gear 42 will drive the second rotating gear 44 connected to the bottom. The second rotating gear 44 will rotate the second rotating rod 43. The rotation of the second rotating rod 43 will drive the bottom rotating ring 45 and the impeller 47 to rotate together. When the rotating ring 45 and the impeller 47 start to rotate, the water stored on one side of the first groove 3 will rotate with the cooperation of the rotating ring 45 and the impeller 47. At this time, the user slides the pushing bar 35 again to restore the blocking block 34. At this time, the water flows from the side of the first groove 3 into the inside of the fifth groove 66 with the cooperation of the rotating ring 45 and the impeller 47. At this time, it will quickly flow out from the eighth hole 68 in the straight water outlet 67 installed on both sides of the water outlet bar 65 to form a large-area water sprinkling, thereby removing dust from the air at the construction site.
