The plurality of main spray heads 6 are arranged in an array along the length direction of the main pipe 5. The free end of the main rod 3 is hinged with an auxiliary rod 7. An auxiliary pipe 8 is provided on the auxiliary rod 7. The auxiliary pipe 8 is fixed on it along the length direction of the auxiliary rod 7. A plurality of auxiliary spray heads 9 are provided on the auxiliary pipe 8. The plurality of auxiliary spray heads 9 are arranged in an array along the length direction of the auxiliary pipe 8. The main pipe 5 and the auxiliary pipe 8 are communicated through a corrugated pipe 10. The free end of the main pipe 5 is communicated with a water inlet hose 11. Two first pulleys 12 are provided on the connecting frame 2. The first pulleys 12 are fixed on the connecting frame 2. The first pulleys 12 are coaxially distributed with the hinge shafts of the main rods 3. Second pulleys 13 are provided on the hinge shafts of the main rods 3 and the auxiliary rods 7. The second pulleys 13 are fixed on the hinge shafts of the main rods 3 and the auxiliary rods 7. A connecting belt 14 is wound around the first pulleys 12 and the second pulleys 13;

[0027] In the initial state, both the main rod 3 and the auxiliary rod 7 tend to be in the vertical direction and form an acute angle between them. During use, one of the main rods 3 is driven to rotate, and through the gear pair 4, the other main rod 3 is driven to rotate synchronously in the opposite direction until both main rods 3 rotate to the horizontal direction. During this process, the connecting belt 14 moves on the first pulley 12 and drives the second pulley 13 to rotate, thereby driving the auxiliary rod 7 to rotate synchronously to the horizontal direction. Then, water is supplied into the two water inlet hoses 11, and the water sequentially enters the main pipe 5, the corrugated pipe 10, and the auxiliary pipe 8.

Conversely, when not in use, one of the main rods 3 is driven to rotate, and through the gear pair 4, the other main rod 3 is driven to rotate synchronously in the opposite direction until both main rods 3 rotate to tend to the vertical direction, thereby reducing the occupied space;

[0028] In summary, when in use, the present application can spray the construction site, reduce the dust pollution in the air, achieve the dust removal effect, and at the same time increase the spraying range, improve the dust removal efficiency and effect. Therefore, it is more practical.

[0029] As Figures 1 - 5 shown, in some embodiments, a connecting pipe 15 is provided on the connecting frame 2. The connecting pipe 15 is fixedly arranged on the connecting frame 2. The free end of the water inlet hose 11 is communicated with the connecting pipe 15. A water tank 16 is provided on the trolley 1. The water tank 16 is fixedly arranged on the trolley 1. A water pump 17 is provided on the water tank 16. The water pump 17 is fixedly arranged on the water tank 16. The input end of the water pump 17 extends to the inner bottom of the water tank 16, and the output end is communicated with the connecting pipe 15;

[0030] Referring to the above, during use, water is added into the water tank 16, the water pump 17 is operated, and the water in the water tank 16 is conveyed into the connecting pipe 15. The water in the connecting pipe 15 is split into two streams and respectively enters the two water inlet hoses 11 to achieve simultaneous water supply into the two water inlet hoses 11, making the use more convenient.

[0031] As Figures 2 - 3 shown, in some embodiments, the inner diameters of the multiple main nozzles 6 increase sequentially along the length direction of the main pipe 5. The inner diameter of the main nozzle 6 closer to the auxiliary pipe 8 is larger, and the inner diameter of the main nozzle 6 farther from the auxiliary pipe 8 is smaller. The inner diameters of the multiple auxiliary nozzles 9 increase sequentially along the length direction of the auxiliary pipe 8. The inner diameter of the auxiliary nozzle 9 closer to the main pipe 5 is smaller, and the inner diameter of the auxiliary nozzle 9 farther from the main pipe 5 is larger;

[0032] Referring to the above, during use, through the sequentially increasing inner diameter setting, it can ensure that the flow velocity and flow rate of the water mist sprayed out by the multiple main nozzles 6 and the multiple auxiliary nozzles 9 are basically kept consistent, thereby improving the uniformity of spraying and further improving the dust removal effect.

[0033] As Figure 2 shown, in some embodiments, two positioning rods 18 are provided on the connecting frame 2. The two positioning rods 18 are both fixedly provided on the connecting frame 2 and are spaced apart. The two main rods 3 are respectively in contact and overlap with the two positioning rods 18;

[0034] Referring to the above, in the initial state, the two main rods 3 are respectively away from the two positioning rods 18. During use, the two positioning rods 18 rotate synchronously in opposite directions and are respectively in contact and overlap with the two positioning rods 18. At this time, the two positioning rods 18 are both in the horizontal direction, so as to achieve the rapid positioning of the positioning rods 18 and make the use more convenient.

[0035] As Figure 4 shown, in some embodiments, the connecting frame 2 is hinged on the trolley 1, and a driving mechanism for driving the connecting frame 2 to rotate reciprocally is provided on the trolley 1;

[0036] Referring to the above, during use, the connecting frame 2 is driven to rotate reciprocally by the driving mechanism, so as to further increase the spraying range, thereby further improving the dust removal efficiency and effect.

[0037] As Figure 4 shown, in some embodiments, the driving mechanism includes a slider 19 slidably provided on the trolley 1. The slider 19 slides in the vertical direction. A strip-shaped groove 20 is formed on the connecting frame 2. The strip-shaped groove 20 is formed along the length direction of the connecting frame 2. A convex block 21 slidably matched with the strip-shaped groove 20 is provided on the slider 19. The convex block 21 is in the horizontal direction and is fixedly provided on the slider 19. A driving member for driving the slider 19 to slide linearly back and forth is provided on the trolley 1;

[0038] Referring to the above, during use, the slider 19 is driven to slide linearly back and forth by the driving member, and the convex block 21 slides back and forth in the strip-shaped groove 20. When the slider 19 slides downward, it drives the connecting frame 2 to rotate upward. On the contrary, when the slider 19 slides upward, it drives the connecting frame 2 to rotate downward. Repeating this way to drive the connecting frame 2 to rotate reciprocally.

[0039] As Figures 6 - 7As shown, in some embodiments, the driving member includes a first connecting rod 22 hinged to the trolley 1. The free end of the first connecting rod 22 is hinged with a second connecting rod 23. The free end of the second connecting rod 23 is hinged with a third connecting rod 24. The free end of the third connecting rod 24 is hinged with the slider 19. An adjusting rod 25 hinged to the second connecting rod 23 is arranged on the trolley 1. The hinge axis of the adjusting rod 25 and the second connecting rod 23 serves as a fulcrum. A driving disk 26 is eccentrically rotatably arranged on the trolley 1. The driving disk 26 is in the vertical direction. A circumferential groove 27 is formed on the driving disk 26. A convex rod 28 slidably engaged with the circumferential groove 27 is arranged on the hinge axis of the first connecting rod 22 and the second connecting rod 23. The convex rod 28 is in the horizontal direction and is fixed on the hinge axis of the first connecting rod 22 and the second connecting rod 23;

[0040] Referring to the above, during use, the driving disk 26 is driven to rotate. Since the driving disk 26 is eccentrically rotatably arranged on the trolley 1, the convex rod 28 will reciprocally slide in the circumferential groove 27, thereby driving the first connecting rod 22 and the second connecting rod 23 to reciprocally rotate about the fulcrum axis together. The third connecting rod 24 is driven by the second connecting rod 23 to reciprocally rotate. The slider 19 is driven by the third connecting rod 24 to linearly reciprocally slide.

[0041] As Figure 7 shown, in some embodiments, a waist-shaped hole 29 is formed on the second connecting rod 23. The waist-shaped hole 29 is formed along the length direction of the second connecting rod 23. The waist-shaped hole 29 has an initial point and a limit point distributed oppositely. A convex column 30 slidably engaged with the waist-shaped hole 29 is arranged on the adjusting rod 25. The convex column 30 is in the horizontal direction and is fixed on the adjusting rod 25. The adjusting rod 25 is slidably arranged on the trolley 1. The adjusting rod 25 slides in the horizontal direction. A lead screw 31 with a thread passing through the adjusting rod 25 is rotatably arranged on the trolley 1. The lead screw 31 is in the horizontal direction;

[0042] Referring to the above, in the initial state, the adjusting rod 25 is located at the initial position and in the middle of the lead screw 31. The convex column 30 is located in the middle of the waist-shaped hole 29. During use, the lead screw 31 can be driven to rotate forward. Due to the thread action, the adjusting rod 25 slides to the limit position and approaches the driving disk 26, driving the convex column 30 to slide to the limit point, changing the position of the fulcrum, increasing the sliding stroke of the slider 19 and the rotation range of the connecting frame 2. On the contrary, driving the lead screw 31 to rotate reversely, the adjusting rod 25 slides to the initial position and moves away from the driving disk 26 due to the thread action, driving the convex column 30 to slide to the initial point, changing the position of the fulcrum, reducing the sliding stroke of the slider 19 and the rotation range of the connecting frame 2. Thus, the spraying range can be adjusted according to the actual use requirements, improving the use flexibility and applicability.

[0043] The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
