[0031] The connecting groove 205 and the arc-shaped flexible baffle 208 are fully covered inside the card slot opened at the top of the first box 207. The extreme positions of the first connecting rod 210 and the second connecting rod 212 are in contact with the outer surface of the connecting groove 205. Three groups of baffles 215 are arranged inside the first box 207. The inner surface of the chute 216 is flush with the inner surface of the collecting trough 218. Multiple groups of atomizing nozzles are fixedly connected inside the first box 207.

[0034] An annular rubber block is fixedly connected to the top of the first annular column 301 and the bottom of the second annular column 302, two groups of first pushing components 3001 are fixedly connected to the outer surface of the second box body 309, two groups of second pushing components 3002 are symmetrically arranged on the outer surface of the third annular column 312, and six groups of adjustment components 3003 are symmetrically arranged on the top of the third annular column 312. By setting the external spray mechanism 3, the cooperation between the internal spray mechanism 2 and the external spray mechanism 3 can improve the dust reduction efficiency. The external spray mechanism 3 reduces the amount of dust entering the construction site and near the dust source, and reduces the workload of the internal spray mechanism 2; at the same time, the precise treatment of the dust source by the internal spray mechanism 2 makes up for the shortcomings of the external spray mechanism 3 in the local dust reduction effect, ensuring that the dust in the entire construction process is effectively controlled.

[0035] The working principle of this embodiment is as follows: when the dust-proof spray device for construction is used, the third motor 311 starts to rotate, driving the fan blade 310 to rotate, and the water mist sprayed from the first nozzle 326 is pushed into the air by wind force for sedimentation. When angle adjustment is required, the first hydraulic pump 306 starts to push the second box body 309 to rotate upward around the axis of the outer surface of the circular column 328 through the second connecting block 307 and the second rotating shaft connecting block 308 to adjust the wind angle, and another set of first pushing components 3001 is set to realize the auxiliary stability adjustment function. When it is necessary to adjust the spray range by adjusting the angle of the first nozzle 326, the second hydraulic pump 315 starts the compression The limiting rod 319 slides in the through hole inside the fifth connecting block 317, driving the fourth annular column 313 to move downward, and the first right-angle baffle 322 and the second right-angle baffle 323 are pressed to rotate around the axis of the fourth rotating shaft connecting block 324. Due to the restriction of the rotation of the first rotating rod 321 around the axis of the third rotating shaft connecting block 320, the first right-angle baffle 322 and the second right-angle baffle 323 are pressed to rotate around the axis of the fourth rotating shaft connecting block 324, and at the same time, they rotate around the axis at the top of the first rotating rod 321, so that the ferrule connecting block 325 is turned outward around the axis of the ferrule connecting block 325, driving the first nozzle 326 to turn outward, thereby expanding the spray range, and the second hydraulic pump 315 is stretched and retracted.

[0036] Example 3: Please refer to Figure 7-Figure 9On the basis of the first and second embodiments, the present invention provides a technical solution: the synchronous adjustment mechanism 4 includes a dust sensor 401, the dust sensor 401 is clamped with the outer surface of the air inlet slot 204, the bottom of the second rotating shaft 213 is fixedly connected with an arc column 402, the bottom of the air inlet slot 204 is fixedly connected with a slot connection block 403 and a first arc block 405, the slot connection block 403 is internally clamped with an electromagnet 404 through a slot, the first arc block 405 is clamped with the annular slot at the top of the first box body 207, the first arc block 405 is internally fixedly connected with a third hydraulic pump 406 by opening a through hole, and the output end of the third hydraulic pump 406 is fixedly connected with the second arc block 40 7. The second arc-shaped block 407 is engaged with the annular groove on the top of the first box body 207. The top of the bracket 201 is fixedly connected with the fourth motor 408 and the fourth hydraulic pump 413. The output end of the fourth motor 408 is fixedly connected with the first gear 409. The outer surface gear of the first gear 409 is connected with the second gear 411. The interior of the second gear 411 is slidably connected with a nail-shaped rotating rod 410 through a through hole. The top of the nail-shaped rotating rod 410 is fixedly connected with the bottom of the top plate 303. The output end of the fourth hydraulic pump 413 is fixedly connected with the first sleeve 412. The outer surface gear of the second gear 411 is connected with the third gear 414. The third gear 414 is fixedly connected with the bottom of the top plate 303.

[0037] The top of the second gear 411 is a complete gear and the bottom is an incomplete gear. The first sleeve 412 is in contact with the bottom of the second gear 411. Two groups of dust sensors 401 are clamped on the outer surface of the air inlet slot 204. By setting a synchronous adjustment mechanism 4, detection is performed with the help of the dust sensor 401, so that the suction direction of the internal spray mechanism 2 is accurately adjusted to be consistent with the dust-dense direction, and the external spray mechanism 3 is prompted to perform swinging spraying, so as to carry out dust reduction in all directions and efficiently, which helps to reduce the pollution of the surrounding environment caused by construction and protect the living environment and air quality of surrounding residents.

[0038] The working principle of this embodiment is as follows: when the dust-proof spray device for construction is used, the dust sensor 401 detects it. If the dust content increases, the electromagnet 404 pushes the arc column 402 downward in the opposite direction, drives the second rotating shaft 213 downward, and drives the triangular clamping block 214 to move out of the slot, so that the power of the air inlet slot 204 fails and the second motor 209 is stopped. At this time, the third hydraulic pump 406 pushes the second arc clamping block 407 downward to tightly engage with the slot on the top of the first box body 207, and the rotation of the air inlet slot 204 is stopped by the friction plate of the second arc clamping block 407. After the friction plate is consumed, the third hydraulic pump 406 can be moved upward to move the second arc clamping block 407 out of the slot to achieve replacement. After the angle of the air inlet slot 204 is fixed The fourth motor 408 rotates to drive the first gear 409 to rotate, the first gear 409 drives the second gear 411 to rotate, the second gear 411 drives the third gear 414 to rotate, and the third gear 414 drives the external spray mechanism 3 to rotate, so that it faces the side with more dust content. After facing, the first nozzle 326 is used for spraying to reduce dust. The fourth motor 408 stops rotating to achieve fixed spraying. When swing spraying is required, the fourth hydraulic pump 413 pushes the first ferrule 412 upward to move upward, so that the gear-connected part is replaced by the incomplete gear part of the second gear 411. At this time, the fourth motor 408 rotates, driving the external spray mechanism 3 to swing, thereby achieving swing spraying.
