Construction workers use various building materials and construction machinery at the construction site to carry out production activities for building various building products according to a specific design blueprint within a certain space and time. Construction is a technically complex production process, including the supply of hundreds of materials and the operation of various construction machinery.

[0003] At the construction site, it is inevitable to have flying dust. In order to prevent the dust from spreading outside the "construction site", usually a fence is used to block it on the outside of the construction site, and at the same time, nozzles are installed on the upper side of the fence. Multiple groups of nozzles are distributed at intervals. Since the nozzles are fixed and the range of the sprayed water mist is limited, the distance between each group of nozzles is relatively short, and the number of required nozzles is also large, which leads to a large amount of water resource consumption and causes a lot of water resource waste.

[0031] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] The present utility model provides a spray dust suppression device as shown in Figure 1 and Figure 5 , which includes a support plate 1. The upper side of the support plate 1 is rotatably connected with a mounting plate 2. The left end of the support plate 1 is fixedly connected with a first connecting block 11. The left end of the lower surface of the mounting plate 2 is fixedly connected with a second connecting block 21. A bolt assembly 22 is inserted into the second connecting block 21. The front and rear ends of the bolt assembly 22 penetrate through the first connecting block 11. A support block 23 is fixedly connected with the left end of the upper surface of the mounting plate 2. The right end of the support block 23 is fixedly connected with an equipment housing 24.

[0033] Among them, when the right end of the mounting plate 2 is lifted upward, at this time, the second connecting block 21 at the left end of the mounting plate 2 rotates around the first connecting block 11 to realize the adjustment of the angle of the mounting plate 2. At the same time, the first connecting block 11 and the second connecting block 21 are locked by the bolt assembly 22, and then the angle of the mounting plate 2 is fixed, improving the stability of the mounting plate 2 during use.

[0034] Refer to Figure 2 and Figure 3 , an adjustment mechanism is provided on the upper side of the mounting plate 2. The adjustment mechanism includes a support block 23, an electric motor 25, a transmission rod 26, a positioning rod 3, a positioning groove 31, and a positioning block 32. The left end of the positioning rod 3 is fixedly connected with a first connecting rod 33. The left end of the first connecting rod 33 is rotatably connected with the upper end of the support block 23. The right end of the positioning rod 3 is fixedly connected with a second connecting rod 34. The electric motor 25 is fixedly installed inside the equipment housing 24. The transmission rod 26 is fixedly connected with the output end of the electric motor 25. The positioning groove 31 is opened on the surface of the positioning rod 3. The positioning block 32 is slidably connected with the positioning groove 31. The end of the transmission rod 26 away from the electric motor 25 is rotatably connected with the lower surface of the positioning block 32.

[0035] In addition, the output end of the electric motor 25 drives the transmission rod 26 to rotate. The end of the transmission rod 26 away from the electric motor 25 drives the positioning block 32 to rotate. At this time, the positioning block 32 will slide left and right inside the positioning groove 31, causing the positioning rod 3 to rotate back and forth around the support block 23 through the first connecting rod 33.

[0036] Specifically, in the initial state, the positioning block 32 is located at the rightmost end of the positioning groove 31. As the transmission rod 26 rotates counterclockwise, the positioning block 32 slides to the right inside the positioning groove 31. At this time, the positioning block 32 will push the positioning rod 3 backward, causing the positioning rod 3 to rotate counterclockwise around the support block 23 through the first connecting rod 33. When the positioning block 32 is at the middle position of the positioning groove 31, the positioning rod 3 rotates to the rearmost end. As the positioning block 32 continues to slide to the left end, at this time, the positioning rod 3 rotates clockwise forward around the support block 23 through the first connecting rod 33. When the positioning block 32 slides to the leftmost end, the positioning rod 3 returns to its original position; as the transmission rod 26 continues to rotate counterclockwise, it drives the positioning block 32 to slide to the right inside the positioning groove 31. At this time, the positioning block 32 will push forward, causing the positioning rod 3 to rotate clockwise around the support block 23 through the first connecting rod 33. When the positioning block 32 is again at the middle position of the positioning groove 31, at this time, the positioning rod 3 rotates to the foremost end. As the positioning block 32 continues to slide to the right end, at this time, the positioning rod 3 rotates clockwise backward around the support block 23 through the first connecting rod 33. When the positioning block 32 slides to the rightmost end of the positioning groove 31, the positioning rod 3 returns to its original position again.

[0037] Refer to Figure 3 and Figure 4 , on the upper surface of the second connecting rod 34, there is a fixed connection with a mounting block 4. On the upper side of the mounting block 4, there are two groups of clamping rings 43. Between the two groups of clamping rings 43, there is an atomizing nozzle 5. The water inlet end of the atomizing nozzle 5 is fixedly connected with a water delivery hose 51. On the upper surface of the mounting block 4, there are two groups of first rotating blocks 41 fixedly connected. At the lower ends of the two groups of clamping rings 43, there are second rotating blocks 42 fixedly connected. The second rotating blocks 42 are rotationally connected with the first rotating blocks 41. At the upper ends of the clamping rings 43, there are locking blocks 45 fixedly connected. Inside the locking blocks 45, there are screws threadedly connected. On the inner walls of the clamping rings 43, there are multiple groups of anti-slip pads 44 fixedly connected.

[0038] In addition, place the atomizing nozzle 5 between the two groups of clamping rings 43. The two groups of clamping rings 43 move closer to the inside to lock and fix the atomizing nozzle 5. As the electric motor 25 drives the positioning rod 3 to rotate, at this time, the positioning rod 3 drives the atomizing nozzle 5 to swing back and forth in a cycle, increasing the spraying range and effectively saving water resources.

[0039] The working principle of the present utility model: The electric motor 25 cooperates with the transmission rod 26, the positioning groove 31, and the positioning block 32 to drive the positioning rod 3 to swing back and forth, thereby driving the atomizing nozzle 5 to swing back and forth, increasing the spraying range of the atomizing nozzle 5, reducing the usage amount of the atomizing nozzle 5, and further reducing the usage amount of water resources, avoiding excessive waste of water resources.
