DETAILED DESCRIPTION

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] See also Figure 1-7 As shown in the figure, this embodiment provides a construction dust reduction device, such as Figure 1 As shown, it includes an isolation baffle 1, and a positioning bolt assembly 2 is fixedly installed at the bottom of the isolation baffle 1. When in use, the isolation baffle 1 is driven into the ground by the positioning bolt assembly 2 to stabilize and limit it, so as to conveniently fence the construction range; a connection power mechanism 3 is fixedly installed on one side of the isolation baffle 1, a first spraying and dust reduction mechanism 4 is provided on the top of the isolation baffle 1, and a second spraying and dust reduction mechanism 5 is provided at the bottom of the isolation baffle 1, and the connection power mechanism 3 can drive the first spraying and dust reduction mechanism 4 to swing back and forth;

[0020] Reference Figure 5-7As shown, the connection power mechanism 3 includes a water storage bucket 33 fixedly installed on one side of the isolation baffle 1, and the outer wall of the water storage bucket 33 is respectively connected with a first water pipe 35 and a second water pipe 36 that penetrates the isolation baffle 1. The first spraying and dust reduction mechanism 4 includes two positioning frames 41 hinged to the first water pipe 35, and one side of the two positioning frames 41 is rotatably connected to a third water pipe 42, and the outer wall of the third water pipe 42 is connected with a plurality of first nozzles 43, and the outer walls of the two third water pipes 42 are fixedly installed with a first limiting sleeve 44, and the outer wall of the first limiting sleeve 44 is rotatably installed. A first support bracket 45 is provided which is rotatably connected to the isolation baffle 1, and a second limiting sleeve 46 is fixedly installed on the outer walls of the two third water pipes 42, and a second support bracket 47 is rotatably connected to the outer wall of the second limiting sleeve 46, and one side of the two second support brackets 47 is rotatably connected to a third support bracket 48 which is arranged in a horizontal state. In the initial state, the two third water pipes 42 are in a state of being close to each other. During dust reduction operation, the connecting power mechanism 3 can drive the third support bracket 48 to rise or fall, thereby driving the two third water pipes 42 to reciprocate towards and away from each other.

[0021] Specifically, under normal conditions, the distance between the two third water pipes 42 is close to each other and close to the vertical center line of the first water pipe 35. At this time, the overall height of the third support bracket 48 is in a low position.

[0022] It is understandable that when a large amount of flying dust is generated at the construction site, the user can start the connection power mechanism 3, so that the liquid in the water storage bucket 33 is sprayed out from the first nozzle 43 through the first water pipe 35 and the third water pipe 42 to form a large number of fine water droplets, which have a sedimentation suppression effect on the dust; at the same time, the connection power mechanism 3 can also drive the third support bracket 48 to rise or fall back and forth, wherein, when the third support bracket 48 is raised as a whole, the third support bracket 48 pushes the second limit sleeve 46 to deflect in the vertical direction away from the center line of the first water pipe 35, and then the two third water pipes 42 are synchronously moved toward each other. Move away, at this time, the third supporting bracket 48 changes from a low position to a high position; on the contrary, when the third supporting bracket 48 is lowered as a whole, the third supporting bracket 48 pulls the second limiting sleeve 46 to deflect toward the vertical center line direction close to the first water pipe 35, and then synchronously makes the two third water pipes 42 approach each other, and the above process is repeated, thereby realizing the reciprocating swing of the first spraying and dust reduction mechanism 4, and in this process, the spraying range of the multiple first nozzles 43 arranged on the two third water pipes 42 continuously changes from large to small and from small to large, avoiding the problem of relatively fixed spraying range of traditional equipment and effectively improving the dust reduction effect.

[0023] Furthermore, combined with Figure 3 and Figure 7As shown, the connection power mechanism 3 also includes a hollow filter cartridge 31 rotatably installed on the outer wall of the water storage barrel 33, and the inner cavity of the water storage barrel 33 is rotatably installed with an electric rotating rod 32 fixedly connected to the hollow filter cartridge 31, and a water guide groove 34 is opened on the top of the water storage barrel 33. Specifically, the purpose of such a setting is to enable the water storage barrel 33 in a normal state to replenish liquid through the water guide groove 34, and to receive outdoor rainwater, and to isolate and filter larger impurities in the rainwater through the hollow filter cartridge 31 covered by the outer wall of the water storage barrel 33, so that the received rainwater can be directly stored and used, and when the electric rotating rod 32 is started to drive the first limit support rod 38 and the second limit support rod 39 to move back and forth up and down, it can also drive the hollow filter cartridge 31 to rotate, so as to remove impurities and dust isolated on the surface of the hollow filter cartridge 31 through centrifugal force.

[0024] Furthermore, combined with Figure 2 and Figure 7 As shown, one end of the electric rotating rod 32 extending out of the isolation baffle 1 is fixedly connected with a special-shaped protrusion 310, and one side of the isolation baffle 1 is fixedly installed with two first positioning slide frames 37, and the inner cavities of the two first positioning slide frames 37 are installed with first limit struts 38 in an up and down sliding state, and a second limit strut 39 is fixedly connected between the two first limit struts 38. When the electric rotating rod 32 rotates, it can drive the first limit strut 38 and the second limit strut 39 to reciprocate up and down, thereby driving the third supporting bracket 48 to rise or fall.

[0025] Specifically, by starting the electric rotating rod 32 to drive the special-shaped protrusion 310 to rotate, and making the guide block 311 at the connection between the two first limit struts 38 and the second limit struts 39 slide on its outer wall, as the trajectory of the outer wall of the special-shaped protrusion 310 changes, the distance between the guide block 311 at the connection and the rotation center point of the special-shaped protrusion 310 changes continuously, which can generate a force on the guide block 311 at the connection between the corresponding first limit strut 38 and the second limit strut 39, so that the first limit strut 38 as a whole slides synchronously in the first positioning slide frame 37.

[0026] Among them, combined Figure 6 As shown, the third supporting bracket 48 and the first limiting support rod 38 are fixedly connected in a mutually perpendicular state. Specifically, when the special-shaped protrusion 310 is pressed against the first limiting support rod 38 to move upward as a whole, the two third water pipes 42 are simultaneously pushed to gradually expand outward and move. When the first limiting support rod 38 pulls the third supporting bracket 48 to move downward, the two third water pipes 42 are synchronously driven to deflect toward the vertical center line position of the first water pipe 35.

[0027] Further, wherein, referring to Figure 2As shown, the two first limiting struts 38 are symmetrically arranged about the horizontal center line of the special-shaped protrusion 310 under normal conditions, and the connection between the first limiting strut 38 and the second limiting strut 39 is rotatably installed with a guide block 311, and the guide block 311 is slidably installed on the outer wall of the special-shaped protrusion 310. The purpose of this arrangement is to maintain a limiting connection between the guide block 311 and the special-shaped protrusion 310 so that it will not slip easily.

[0028] Furthermore, combined with Figure 3 and Figure 5 As shown, the second spraying and dust reduction mechanism 5 includes a second nozzle 51 which is connected to the bottom of the second water pipe 36, and the second nozzle 51 and the second water pipe 36 are arranged in a rotationally connected state. A limiting sleeve 52 is fixedly installed on the outer wall of the second nozzle 51, and a dust blocking pressure plate 53 fixedly connected to the first limiting support rod 38 is slidably installed on the outer wall of the limiting sleeve 52. Specifically, the purpose of such a setting is to enable the dust blocking pressure plate 53 to slide up and down synchronously when the first limiting support rod 38 is driven to move up and down.

[0029] A second positioning slide frame 54 is fixedly mounted on the outer wall of the second water conduit 36 ​​, a dust shield pressing plate 53 is slidably mounted in the inner cavity of the second positioning slide frame 54 , and a telescopic spring 55 fixedly connected to the first positioning slide frame 37 is fixedly mounted on the dust shield pressing plate 53 .

[0030] Furthermore, combined with Figure 4 As shown, the outer wall of the limiting sleeve 52 is provided with two first guide grooves 56, and the outer wall of the limiting sleeve 52 is provided with two second guide grooves 57 connected to the first guide grooves 56, and the inner cavity of the first guide groove 56 is slidably installed with a positioning slider 58 fixedly connected to the dust shield pressure plate 53.

[0031] Specifically, the first guide groove 56 can be set to a slowly changing arc, wherein the two first guide grooves 56 are set in a horizontal state, and the horizontal center lines of the two first guide grooves 56 are set in a symmetrical state with respect to the horizontal center line of the limiting sleeve 52, and the two second guide grooves 57 are set in a sloped state.

[0032] It can be understood that in actual use, when the electric rotating rod 32 is started to drive the first limit support rod 38 and the second limit support rod 39 to move reciprocatingly up and down, it can not only drive the third supporting bracket 48 to rise or fall, thereby realizing the reciprocating swing spraying of the first spraying and dust reduction mechanism 4, but also drive the dust blocking pressure plate 53 fixedly connected to the first limit support rod 38 to move reciprocatingly up and down synchronously on the periphery of the limit sleeve 52, so that the dust blocking pressure plate 53 drives the positioning slider 58 to move up and down synchronously, and then the positioning slider 58 can follow the trajectory of the arc-shaped high and low slide rails. The dust blocking pressure plate 53 moves up and down as a whole, and the limiting sleeve 52 drives the second nozzle 51 to rotate as a whole. This realizes the rotary spraying of dust reduction on the ground, and the dust blocking pressure plate 53 moves up and down during the spraying process, so that the dust reduction water sprayed by the second nozzle 51 is limited and pressed at the bottom range to avoid splashing the dust on the ground when the dust reduction water is sprayed onto the ground, causing the problem of dust flying.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
