[0052] The ends of the threaded rods 19 away from the fixing ring 20 are fixedly connected to a circular plate 40 , and the diameter of the circular plate 40 is larger than the outer surface diameter of the threaded rods 19 .

[0053] With this design, the circular plate 40 can limit the movement of the threaded rod 19, thereby preventing the threaded rod 19 from separating from the circular plate 18 and improving the stability of the device during use.

[0054] like Figure 6As shown, a water supply component 10 is provided on the outer wall of the main pipe 1 , and the output end of the water supply component 10 is connected to the movable pipe 4 and the annular pipe 8 respectively, for conveying water into the movable pipe 4 and the annular pipe 8 .

The other ends of the hoses 26 are fixedly connected to the corresponding movable tubes 4. The bottom end of the circular tube 25 is fixedly connected to the water inlet pipe 27.

[0056] In this embodiment, a water pump is fixedly installed on the water inlet pipe 27 , and the water inlet end of the water pump is connected to an external water source. The water pump is used to suck water from the external source and inject it into the annular tube 25 through the water inlet pipe 27 .

[0062] The elastic rubber ring 31 extends into the annular groove 28 near one end of the main pipeline 1 and is fixedly connected with the mounting ring 29; through the cooperation of the spring 30 and the mounting ring 29, the elastic rubber ring 31 is elastically connected between one end of the elastic rubber ring 31 and the front end face of the main pipeline 1, facilitating assembly and installation.

[0063] In this way, during the movement of the movable pipe 4, the elastic rubber ring 31 is moved by the movable pipe 4 to extend out of the annular groove 28 by a specified length, at this time, the mounting ring 29 is pulled by the spring 30, the mounting ring 29 pulls the elastic rubber ring 31, and under the elastic force of the elastic rubber ring 31, the front side of the elastic rubber ring 31 is stretched by the movable pipe 4 to form a specified size of the caliber, that is, the adjustment operation of the spray outlet caliber can be completed.

[0064] When the airflow in the main pipeline 1 is blown out by the fan 2 through the elastic rubber ring 31, because the caliber changes, the airflow velocity can be changed, so that the spray can be blown farther, and in the case that the power of the fan 2 is constant, the spray dust removal operation at a farther position can be completed.

[0065] As shown in Figure 3 and Figure 8 , the support 12 is movably installed on the main pipeline 1, the control box 13 is installed on the front side wall of the support 12, and the bottom plate 14 is arranged at the bottom surface, the driving assembly 15 is arranged on the support 12, and the driving assembly 15 is used for driving the main pipeline 1 to pitch and swing and to rotate circumferentially.

[0076] S1: Fix the spray dust removal device to the specified position through the base plate 14 to complete the installation operation of the spray dust removal device, connect the external power supply, start the electric push rod 32 and the drive motor 33 according to the needs of the spray dust removal direction, the electric push rod 32 drives the main pipe 1 to rotate, so that the main pipe 1 rotates to the specified pitch angle, and the drive motor 33 drives the circular shaft 36 and the bracket 12 to rotate through the second transmission assembly, so that the main pipe 1 rotates to the specified circumferential angle.

[0077] In step S1, the working principle of the second transmission assembly is: the driving motor 33 is started to drive the rotating shaft 34 to rotate, and the rotating shaft 34 drives the first gear 35 to engage the second gear 37 to rotate, so that the bracket 12 rotates around the circular axis 36, and the main pipe 1 is rotated to a specified circumferential angle for easy use.

[0078] S2: Then start the position motor 22 according to the distance or range of the spray dust removal. The position motor 22 drives all the threaded rods 19 to rotate together through the first transmission assembly. The threaded rods 19 engage the annular plate 18 to move. The annular plate 18 drives the movable shell 17, the connecting plate 16 and the movable tube 4 to move synchronously. The movable tube 4 drives the arc tube 5 thereon to move, and changes the spacing between the arc tubes 5 to a specified size. Then, the position motor 22 is turned off.

[0079] In step S2, the working principle of the first transmission component is: the position motor 22 starts to drive the corresponding threaded rod 19 to rotate, and the threaded rod 19 drives the sprocket 21 to rotate.

When the movable tube 4 slides along its axial direction, the connecting plate 16 slides in the movable shell 17 to support the movement of the movable tube 4, which is convenient for use.

[0081] S3: As the movable tube 4 moves, the movable tube 4 drives the elastic rubber ring 31 to move, so that the elastic rubber ring 31 extends out of the length specified by the annular groove 28. The spring 30 pulls the mounting ring 29, and the mounting ring 29 pulls the elastic rubber ring 31. Under the elastic force of the elastic rubber ring 31, the front side of the elastic rubber ring 31 is stretched by the movable tube 4 to form a specified diameter, thereby completing the adjustment operation of the spray discharge diameter.

[0082] S4: A water pump is fixedly installed on the water inlet pipe 27. The water inlet end of the water pump is connected to an external water source. The water pump fills water into the water inlet pipe 27. The water in the annular pipe 25 enters the connecting pipe 24 and the hose 26 respectively. The water in the connecting pipe 24 enters the annular pipe 8 and is sprayed out from the second nozzle 9 to realize the spray function inside the main pipe 1. The water in the hose 26 enters the arc pipe 5 through the movable pipe 4 and is then sprayed out through the first nozzle 6 to realize the spray function outside the main pipe 1.

[0083] S5: At the same time, the fan 2 is started, and the fan 2 inputs the external gas into the main pipe 1.
