All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: an atomizing dust suppression device for subway construction dust removal, including a control box 1.

A rotating disk 8 is fixedly welded to the lower part of the rotating shaft 2. A gear ring 9 is fixedly welded to the outer side of the lower part of the rotating disk 8. An internal gear 10 is fixedly welded to the middle side of the lower part of the rotating disk 8. The gear directions of the gear ring 9 and the internal gear 10 are opposite. A connecting gear 11 is meshed in the middle of the internal gear 10 and the gear ring 9. A rotating rod 15 is fixedly welded to the lower part of the connecting gear 11. A lower bevel gear 14 is fixedly welded to the lower part of the rotating rod 15. The lower part of the lower bevel gear 14 is rotatably connected to the inner wall of the control box 1. An upper bevel gear 13 is meshed with the upper part of the lower bevel gear 14. The tail of the upper bevel gear 13 is connected by a coupling to a motor 12. The motor 12 is flange-mounted on the inner wall of the control box 1. The motor 12 drives the upper bevel gear 13 to rotate. The lower bevel gear 14 drives the connecting gear 11 to rotate through the rotating rod 15. The connecting gear 11 is meshed with the gear ring 9 and the internal gear 10 in sequence, so as to drive the receiving seat 3 to rotate back and forth through the rotating shaft 2;
[0021] A fixing piece 6 is fixedly welded to the upper part of the rotating shaft 2. An installation frame 4 is rotatably installed on the outer side of the upper part of the rotating shaft 2. A torsion spring 7 is fixedly welded to the upper part of the installation frame 4. The torsion spring 7 is sleeved on the outer side of the rotating shaft 2. The upper part of the torsion spring 7 is fixedly welded to the fixing piece 6. The torsion spring 7 drives the installation frame 4 to rotate together with the receiving seat 3 on the upper part of the rotating shaft 2. A spray gun 5 is rotatably installed between the upper parts of the installation frame 4, realizing the reciprocating spraying of the spray gun 5 and expanding the spraying area. A number of groups of limiting grooves 16 are formed in the upper part of the control box 1. An insertion rod 18 is slidably installed inside the limiting grooves 16. A connection disk 17 is fixedly welded to the upper part of the insertion rod 18. The height of the connection disk 17 is lower than that of the installation frame 4. A blocking rod 19 is fixedly welded to the upper part of the connection disk 17. By inserting the insertion rod 18 into the corresponding limiting groove 16, the blocking rod 19 on the upper part of the connection disk 17 blocks the rotating installation frame 4, thereby controlling the maximum rotation angle of the installation frame 4. A storage box 20 is fixedly welded to one side of the control box 1. If the angle is not limited, the integrally connected insertion rod 18, connection disk 17 and blocking rod 19 can be stored. A protection box 21 is fixedly welded to the inner upper wall of the control box 1. The limiting groove 16 penetrates the control box 1 and faces the inside of the protection box 21 to prevent water from dripping into the control box 1 through the limiting groove 16 and damaging the internal electrical structure. A connecting rod 22 is fixedly welded to the upper part of the fixing piece 6. Two groups of first connection blocks 23 are rotatably installed on the outer side of the connecting rod 22. Two groups of first connection pieces 24 are fixedly welded to one side of the first connection blocks 23. A damping rod 25 is rotatably connected between the first connection pieces 24.

The upper and lower sides of the second connection block 26 are rotationally connected to second connection pieces 27. The second connection pieces 27 are fixedly welded to the installation frame 4. When the fixing piece 6 and the installation frame 4 are offset, the connecting rod 22 drives one end of the damping rod 25 to move through the first connection block 23 and the first connection piece 24, and stretches or pushes the damping rod 25. The other end of the damping rod 25 rotates around the second connection piece 27 through the second connection block 26 to buffer the elastic force of the torsion spring 7 and prevent the installation frame 4 from rotating back and forth.
[0022] Working principle: When this utility model is in use, the motor 12 drives the upper bevel gear 13 to rotate. The lower bevel gear 14 drives the connecting gear 11 to rotate through the rotating rod 15. The connecting gear 11 meshes with the gear ring 9 and the internal gear 10 in sequence, so as to drive the receiving seat 3 to rotate back and forth through the rotating shaft 2. The torsion spring 7 drives the mounting bracket 4 to rotate together with the receiving seat 3 on the upper part of the rotating shaft 2, realizing the back-and-forth spraying of the spray gun 5 and expanding the spraying area. By inserting the insertion rod 18 into the corresponding limiting groove 16, the blocking rod 19 on the upper part of the connecting disc 17 blocks the rotating mounting bracket 4, thereby controlling the maximum rotation angle of the mounting bracket 4. When the fixing piece 6 is offset from the mounting bracket 4, the connecting rod 22 drives one end of the damping rod 25 to move through the first connecting block 23 and the first connecting piece 24, and stretches or pushes the damping rod 25. The other end of the damping rod 25 rotates around the second connecting piece 27 through the second connecting block 26, buffering the elastic force of the torsion spring 7 and preventing the mounting bracket 4 from rotating back and forth.
