Detailed Implementation

[0022] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] An embodiment provides a dust control device for construction projects, such as... Figures 1-4 As shown, the device includes a work box 1, which is a rectangular box structure with an L-shaped working groove at its front end. An adjusting plate 2 is installed inside the L-shaped working groove, and auxiliary shafts 3 are fixedly connected to both ends of the adjusting plate 2. The adjusting plate 2 is rotatably connected to the work box 1 via the auxiliary shafts 3, allowing it to rotate back and forth within the L-shaped working groove. A support plate 12 is located above the work box 1, and a water sprayer 17 is installed on the support plate 12. A hollow groove is formed on the support plate 12 corresponding to the position of the L-shaped working groove, and an auxiliary plate 13 is rotatably connected within the hollow groove. The end of the support plate 12 furthest from the auxiliary plate 13 is rotatably connected to the work box 1 via two sets of rotating frames. Each set of rotating frames includes a bracket 16 fixed to the work box 1, a support shaft 15 fixedly installed on the bracket 16, and supports 14 rotatably connected to both ends of the support shaft 15. The supports 14 are fixedly connected to the support plate 12, and the support plate 12 rotates along the support shaft 15 via the supports 14. The auxiliary plate 13 is connected to the adjustment plate 2 via an adjustment frame below, and the height of one end of the support plate 12 is adjusted by the adjustment frame, thereby adjusting the up and down spray angle of the water sprayer 17.

[0024] In this embodiment, the adjustment frame includes a servo motor 4 fixedly connected to the front side wall of the adjustment plate 2. The output end of the servo motor 4 is fixedly connected to a rotating shaft 5. The rear end of the rotating shaft 5 is fixedly connected to a first bevel gear 6. The back of the first bevel gear 6 is fixedly connected to a first connecting plate 7. The right side of the first bevel gear 6 is meshed with a second bevel gear 8. The right side of the second bevel gear 8 is fixedly connected to a central rotating shaft 9. The outer surface of the central rotating shaft 9 is fixedly sleeved with a second connecting plate 10. A third connecting plate 11 is rotatably connected above both the first connecting plate 7 and the second connecting plate 10. The other ends of the two sets of third connecting plates 11 are rotatably connected to an auxiliary plate 13, respectively. Through the combined action of the servo motor 4 and the rotating shaft 5, the first bevel gear 6 can rotate, which in turn drives the first connecting plate 7 to rotate at a certain angle. Simultaneously, the first bevel gear 6 can drive the second bevel gear 8 to rotate, which in turn drives the second connecting plate 10 to rotate at a certain angle. This causes the first connecting plate 7 and the second connecting plate 10 to drive the corresponding third connecting plate 11 to rotate, thereby adjusting the distance between the adjusting plate 2 and the auxiliary plate 13. The adjusting plate 2 can rotate inside the working box 1, and the auxiliary plate 13 can rotate inside the support plate 12. With the combined action of the support 14, the support shaft 15, and the bracket 16, the angle of the support plate 12 can be adjusted, thereby adjusting the angle of the water sprayer 17.

[0025] An embodiment provides a dust control device for construction projects, such as... Figures 1-4 As shown, the water sprayer 17 has a hose 18 connected to its input end. The working box 1 has a water storage chamber 27 on the side away from the working tank. The bottom end of the hose 18 passes through the upper surface of the support plate 12 and the upper surface of the working box 1 and extends into the water storage chamber 27. The working box 1 has an input pipe 19 and an output pipe 20 at the positions corresponding to the water storage chamber 27. Both the input pipe 19 and the output pipe 20 are equipped with regulating valves. The input pipe 19 and the output pipe 20 make it more convenient for workers to input and output water into and out of the working box.

[0026] An embodiment provides a dust control device for construction projects, such as... Figures 1-4 As shown, a horizontal plate 21 is fixedly connected to the upper surface of the water sprayer 17, a main shaft 22 is fixedly connected to the right end of the lower surface of the horizontal plate 21, a ball bearing 23 is fixedly connected to the bottom end of the outer surface of the main shaft 22, and a swing mechanism 24 is provided above the support plate 12. Figure 1 and Figure 2As shown, the swing mechanism 24 includes a drive motor 2401, which is fixedly mounted on the right side above the support plate 12. A transmission shaft 2402 is fixedly connected to the output end of the drive motor 2401. A transmission plate 2403 is fixedly connected to the top end of the transmission shaft 2402. A smooth shaft 2404 is fixedly connected to the right end of the upper surface of the transmission plate 2403. A swing plate 2405 is fixedly sleeved on the outer surface of the main shaft 22. A limit hole is opened on the right side of the swing plate 2405. The smooth shaft 2404 is located inside the right side of the limit hole. The outer surface of the smooth shaft 2404 contacts the inner side wall of the swing plate 2405. A limit cap 2408 is fixedly connected to the top end of the smooth shaft 2404. In order to make the water sprayer 17 swing to a certain extent and further increase the water spray coverage area, under the cooperation of the drive motor 2401 and the transmission shaft 2402, the transmission plate 2403 can drive the smooth shaft 2404 to move to a certain extent inside the swing plate 2405, so that the swing plate 2405 swings at a certain angle under the cooperation of the main shaft 22 and the ball bearing 23. Through the connection of the cross plate 21, the main shaft 22 can drive the water sprayer 17 to swing.

[0027] In actual setup, the smooth shaft 2404 can make circular motion inside the limiting hole under the rotation of the transmission plate 2403, thereby causing the swing plate 2405 to swing around the left main shaft 22. The limiting cap 2408 can prevent the smooth shaft 2404 from running out of the limiting hole during movement, thus extending the service life of the device.

[0028] like Figure 1 and Figure 3 As shown, to provide some support for the water sprayer 17, a support frame 2406 is fixedly connected to the lower surface of the water sprayer 17. Two sets of smooth ball bearings 2407 are rotatably mounted on the lower surface of the support frame 2406, and the lower surface of the smooth ball bearings 2407 contacts the upper surface of the support plate 12. To ensure that the bottom end of the hose 18 is stably located inside the bottom of the working box 1, a gravity ball 26 is fixedly fitted onto the bottom end of the outer surface of the hose 18. The gravity ball 26 is shaped as a flat sphere. To ensure that the water inside the working box 1 is located as far as possible on the left side, the bottom surface of the water storage chamber 27 of the working box 1 is inclined with the right side higher than the left side. The input pipe 19 is located at the highest point of the inclined bottom surface of the water storage chamber 27, and the output pipe 20 is located at the lowest point of the inclined bottom surface of the water storage chamber 27. To facilitate the movement of the device, support plates 28 are fixedly connected to the middle left side of the lower surface of the working box 1, as well as the front right side and rear right side of the lower surface. Wheels 29 are rotatably mounted on the support plates 28.

[0029] The working process of this utility model is as follows: In use, the device is first moved to a suitable position on the construction site. An appropriate amount of water is input into the device through the input pipe 19. The water sprayer 17 draws out the water and sprays it onto the construction site to treat dust. The spraying angle of the water sprayer 17 can be adjusted. The servo motor 4 and the rotating shaft 5 work together to rotate the first bevel gear 6. The first bevel gear 6 drives the first connecting plate 7 to rotate at a certain angle. Simultaneously, the first bevel gear 6 drives the second bevel gear 8 to rotate, which in turn drives the second connecting plate 10 to rotate at a certain angle. This causes the first connecting plate 7 and the second connecting plate 10 to respectively drive the corresponding third connecting plate 11 to rotate, thereby adjusting the relationship between the adjusting plate 2 and the auxiliary plate 13. The distance between the two plates can be adjusted. The adjusting plate 2 can rotate inside the working box 1, and the auxiliary plate 13 can rotate inside the support plate 12. With the cooperation of the support 14, the support shaft 15 and the bracket 16, the angle of the support plate 12 can be adjusted, thereby adjusting the angle of the water sprayer 17. The water sprayer 17 can also swing to a certain extent, further increasing the water spray coverage area. With the cooperation of the drive motor 2401 and the transmission shaft 2402, the transmission plate 2403 can drive the smooth shaft 2404 to move to a certain extent inside the swing plate 2405. The swing plate 2405 swings at a certain angle with the cooperation of the main shaft 22 and the ball bearing 23. Through the connection of the cross plate 21, the main shaft 22 can drive the water sprayer 17 to swing, improving practicality.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
