[0024] See Figures 1 - 5 , this embodiment provides a spray dust suppression device for building construction with a filtering function, including a box body 1. The box body 1 is made of high-strength plastic and has sufficient capacity to accommodate a water pump assembly 8. A spray device 2 is assembled on the top of the box body 1 for spraying water mist to achieve the dust suppression effect. The spray device 2 is installed at the top of the box body 1 so as to spray water mist evenly and reduce the dust pollution at the construction site.

[0026] See Figures 1 - 6, on the basis of the first embodiment, a cleaning and filtering device 3 is assembled on the top of the box body 1. The cleaning and filtering device 3 is used to remove impurities or dirt that may exist inside the filter plate 315. The cleaning and filtering device 3 includes a vertical block, which serves as a support structure and is installed on the top of the box body 1 and is connected to the turntable 33 through a bearing. A toothed block is installed on the turntable 33. The rotation of the runner 26 drives the turntable 33 to rotate through two circular gears 37 to achieve power transmission. The vertical block is fixedly connected to the top of the box body 1. The back of the vertical block is rotatably connected to the turntable 33 through a bearing. The outer wall of the turntable 33 is fixedly connected with a toothed block. The side of the vertical block is fixedly connected with a fixed block 31. The inner wall of the fixed block 31 is rotatably connected with a second rotating rod 32. Both sides of the second rotating rod 32 are fixedly connected with circular gears 37. The back of the turntable 33 is fixedly connected with a cylinder 36. A collar 34 is slidably connected to the outer wall of the cylinder 36. The side of the collar 34 is fixedly connected with a first connecting rod 35. The first connecting rod 35 extends to both sides through the vertical block movably. The bottom of the first connecting rod 35 is fixedly connected with a moving rod 38. The bottom of the moving rod 38 is fixedly connected with a first permanent magnet 39. The first permanent magnet 39 is magnetically connected to a first magnetic conductor 310. The bottom of the first magnetic conductor 310 is fixedly connected with a moving block 311. The bottom of the moving block 311 is fixedly connected with a second permanent magnet 312. The bottom of the second permanent magnet 312 is magnetically connected to a second magnetic conductor 313. The bottom of the second magnetic conductor 313 is fixedly connected with a scraper 314. The scraper 314 is located at the bottom of the filter plate 315 to help remove fine particles or debris attached to the surface of the filter plate 315 and further improve the filtering effect. The front inner wall of the box body 1 is fixedly connected with a filter plate 315. The first magnetic conductor 310 is arranged on the top of the inner wall of the box body 1, and the second magnetic conductor 313 is arranged at the bottom of the filter plate 315. The two circular gears 37 are respectively meshed with the gear installed on the outer wall of the runner 26 and the gear installed on the outer wall of the turntable 33. The two circular gears 37 are meshed with the gear on the outer wall of the runner 26 and the gear on the outer wall of the turntable 33 to form an accurate mechanical transmission system, enabling the rotation of the turntable 33 and the runner 26 to proceed synchronously. This design ensures the coordinated operation of the cleaning and spray adjustment functions.

[0027] When the above device is in specific use, when the runner 26 rotates, it drives the gear block installed on the outer wall to drive the circular gear 37 to rotate. The circular gear 37 at the bottom of the runner 26 drives the second rotating rod 32 to rotate. The second rotating rod 32 drives the circular gear 37 at the bottom of the turntable 33 to rotate. The circular gear 37 at the bottom of the turntable 33 drives the gear block installed on the outer wall of the turntable 33 to rotate. The turntable 33 drives the cylinder 36 to rotate. The cylinder 36 drives the collar 34 to move to the left. The collar 34 drives the first connecting rod 35 to move to the left. The first connecting rod 35 drives the moving rod 38 to move to the left. The moving rod 38 drives the first permanent magnet 39 to move to the left. The first permanent magnet 39 drives the first magnetic conductor 310 to move to the left. The first magnetic conductor 310 drives the moving block 311 to move to the left. The moving block 311 drives the second permanent magnet 312 to move to the left. The second permanent magnet 312 drives the second magnetic conductor 313 to move to the left. The second magnetic conductor 313 pushes the scraper 314 to scrape the impurities at the bottom of the filter plate 315. Since the turntable 33 continuously drives the cylinder 36 to rotate, the collar 34 will cause the scraper 314 to perform reciprocating cleaning to ensure that the surface of the filter plate 315 is always unobstructed and prevent blockage caused by impurity accumulation. Since the turntable 33 continuously drives the cylinder 36 to rotate, the cylinder 36 reciprocally drives the collar 34 to reciprocate, so that the left and right scrapers 314 reciprocally clean the bottom of the filter plate 315. Embodiment

[0028] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 On the basis of Embodiment 1, a fixing device 4 is assembled on the top of the box body 1. The fixing device 4 includes a spherical groove 41. The spherical groove 41 is opened on the front of the runner 26. A second spherical rod 44 is slidably connected to the inner wall of the spherical groove 41. A spring 45 is fixedly connected to the bottom of the second spherical rod 44. A limiting block 46 is fixedly connected to the outer wall of the second spherical rod 44. A second connecting rod 47 is fixedly connected to the side of the limiting block 46. A connecting plate 48 is fixedly connected to the side of the second connecting rod 47. A conical barrel 49 is fixedly connected to the bottom of the connecting plate 48. A fixing rod 42 is fixedly connected to the top of the box body 1. A rubber wheel 43 is rotatably connected to the inner wall of the fixing rod 42. The outer wall of the rubber wheel 43 fits with the inner wall of the fixing rod 42. Through the friction between the rubber wheel 43 and the inner wall of the fixing rod 42, the second spherical rod 44 slowly rises.

[0029] When the above-mentioned device is in specific use, the runner 26 rotates during operation. The rotation of the runner 26 drives the second spherical rod 44 to descend through the spherical groove 41. The descent of the second spherical rod 44 compresses the spring 45. As the second spherical rod 44 descends, it drives the limit block 46 to descend. The limit block 46 drives the second connecting rod 47 to descend, and the second connecting rod 47 drives the connecting plate 48 to descend. The descent of the connecting plate 48 drives the conical barrel 49 to descend. The conical barrel 49 presses the universal head brake on the brake caster 7, fixing the box body 1, achieving the effect of fixing the box body 1 and improving the stability of the spraying device 2 during use. When the spherical groove 41 is aligned with the second spherical rod 44, without the restriction of the runner 26, the spring 45 drives the second spherical rod 44 to rise. At the same time, due to the large frictional force generated between the rubber wheel 43 and the inner wall of the fixed rod 42, the second spherical rod 44 rises slowly. When the runner 26 drives the spherical groove 41 away, the runner 26 presses the second spherical rod 44 again. The ascending length of the second spherical rod 44 in a short time will not cause the universal head brake on the top of the brake caster 7 to fail. After the spraying device 2 finishes using, the motor 27 drives the first rotating rod 25 to align the spherical groove 41 on the front of the runner 26 with the second spherical rod 44, waiting for the second spherical rod 44 to fit with the spherical groove 41, releasing the universal head brake on the top of the brake caster 7, and pushing the handle 5 to move the box body 1.

[0030] When the above-mentioned device is in specific use, as described above, this is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
