The first motor 6 is installed below the base 1. The output end of the first motor 6 is installed with a driving gear 7. The right side of the driving gear 7 is meshed with the driven gear 8. The top of the driven gear 8 is installed with a rotating rod 9. The bottom screw 10 is meshed inside the rotating rod 9. The top plate 11 is installed on the top of the bottom screw 10. The telescopic rod 12 is installed on the front and back sides of the rotating rod 9. The outer periphery of the telescopic rod 12 is wrapped with a spring 13.

[0027] The dust suppression assembly includes a water tank 4, a water pipe 5, a first rotating shaft 14, a support plate 15, a spray hole 16, a second rotating shaft 17, an adjusting rod 18, a third rotating shaft 19, a sleeve rod 20, an upper screw 21, a support frame 22, a second motor 23, a driving wheel 24, a driven wheel 25 and a transmission belt 26. A water tank 4 is installed on the upper left side of the base 1, and a water pipe 5 is installed inside the water tank 4. The first rotating shaft 14 is installed on both sides of the left side of the top plate 11, and the support plate 15 is installed on the other side of the first rotating shaft 14. The support plate 15 and the water pipe 5 are in communication with each other. The bottom array of the first rotating shaft 14 is provided with a spray hole. Hole 16, a second rotating shaft 17 is installed on the top of the support plate 15, an adjusting rod 18 is installed on the other end of the second rotating shaft 17, a third rotating shaft 19 is installed on the other end of the adjusting rod 18, a sleeve rod 20 is installed on the other side of the third rotating shaft 19, an upper screw rod 21 is meshedly installed inside the sleeve rod 20, a support frame 22 is installed outside the sleeve rod 20, a second motor 23 is installed on the top of the support frame 22, a driving wheel 24 is connected to the output end of the second motor 23, a driven wheel 25 is installed in front of the driving wheel 24, and the driving wheel 24 and the driven wheel 25 are connected by a transmission belt 26.

[0028] The rotating rod 9 forms a rotating structure through the cooperation between the driven gear 8 and the driving gear 7, and the bottom screw 10 forms a lifting structure through the rotating rod 9. During use, the first motor 6 drives the driving gear 7, and then the driving gear 7 drives the driven gear 8 meshed on the right side to rotate inside the device.

[0029] When the driven gear 8 rotates, it drives the rotating rod 9 to rotate inside the device, and then the bottom screw 10 engaged inside the rotating rod 9 will be driven to rise and fall inside the device, and when rising and falling, it will drive the top plate 11 to rise and fall inside the device.

[0030] The top plate 11 forms a lifting structure through the bottom screw 10, and the top plate 11 forms a lifting structure through the cooperation between the telescopic rod 12 and the spring 13. The top plate 11 forms a pressing structure with the base 1 through the spring 13. When the top plate 11 is lifted or lowered, it is supported by the telescopic rod 12 and the spring 13 on the front and rear sides to improve the balance and stability of the top plate 11. At the same time, the spring 13 can improve the stability of the top plate 11 and reduce the degree of lifting of the top plate 11.

[0031] Example 2

[0032] like Figure 1-Figure 4 As shown, this embodiment further illustrates Example 1, the support plate 15 forms a rotating structure through the first rotating shaft 14 and the top plate 11, and the support plate 15 array is installed with three groups. During use, the support plate 15 is rotated through the first rotating shaft 14 on the left and the top plate 11, so as to adjust the angle of the support plate 15 inside the device, so as to adjust the angle of the water mist sprayed by the device during use, which is convenient for lowering dust in the air during the construction process, reducing dust on the construction site, and preventing dust from being blown into other spaces, thereby playing a dust-proof role, and the support plate 15 array is provided with three groups, which can increase the amount of water mist sprayed into the air.

[0033] The support plate 15 forms a rotating structure with the adjusting rod 18 through the second rotating shaft 17, and the adjusting rod 18 forms a rotating structure with the sleeve rod 20 through the third rotating shaft 19. During use, the adjusting rod 18 will rotate with the support plate 15 through the second rotating shaft 17 at the end when adjusting the angle, so as to avoid the adjusting rod 18 and the support plate 15 being fixed to each other and causing the support plate 15 to be unable to move. At the same time, the third rotating shaft 19 on the other side of the adjusting rod 18 can rotate with the sleeve rod 20, so as to improve the flexibility of the bag during use.

[0034] The sleeve rod 20 forms a lifting structure through the upper screw rod 21 and the support frame 22. The sizes of the adjusting rod 18 and the support frame 22 are consistent with each other. The upper screw rod 21 is driven to rotate by the second motor 23, and then the upper screw rod 21 drives the externally engaged sleeve rod 20 to rise and fall inside the device. During the lifting process, the sleeve rod 20 will adjust the angle with the adjusting rod 18 through the third rotating shaft 19 on both sides. Since the length of the adjusting rod 18 is fixed, when the sleeve rod 20 rises, the adjusting rod 18 will drive the second rotating shaft 17 on the right to increase the height, and the second rotating shaft 17 will drive the support plate 15 to move upward. Then the support plate 15 will change its angle inside the device, thereby changing the angle of spraying water mist in the air, thereby improving the dust reduction and dust prevention effect.

[0035] The driven wheel 25 forms a transmission structure with the driving wheel 24 through the transmission belt 26. The driving wheel 24, the driven wheel 25 and the transmission belt 26 are provided in two parallel groups. When the second motor 23 rotates, it drives the driving wheel 24 to rotate inside the device. Then, the driving wheel 24 drives the driven wheel 25 to rotate through the transmission belt 26. In this way, the rotation speed of the two driven upper screws 21 can be kept consistent, so the angle adjustment of the support plates 15 on both sides is also consistent. In addition, two groups of driving wheels 24, driven wheels 25 and transmission belts 26 are provided, so that the three groups of upper screws 21 can be driven at the same speed, thereby improving the stability of the device during use.

[0036] During use: first, water required for dust reduction is loaded in the water tank 4, and then the water inside is connected to the support plate 15 through the water pipe 5, and then the first motor 6 drives the driving gear 7, and then the driving gear 7 drives the driven gear 8 engaged on the right side to rotate inside the device, and the driven gear 8 drives the rotating rod 9 to rotate inside the device when rotating, and then the bottom screw 10 engaged inside the rotating rod 9 will be driven to rise and fall inside the device, and when rising and falling, it will drive the top plate 11 to rise and fall inside the device, and when the top plate 11 is raised and lowered, the dust reduction mechanism on the top can be adjusted to rise and fall inside the device, which can adapt to different construction engineering environments. When the top plate 11 is raised and lowered, it is supported by the telescopic rods 12 and the springs 13 on the front and rear sides to improve the balance and stability of the top plate 11. At the same time, the spring 13 can improve the stability of the top plate 11, reduce the degree of the top plate 11 during the lifting process, and then

[0037] The rear upper screw rod 21 is driven by the second motor 23 to rotate, and then the upper screw rod 21 drives the external meshing sleeve rod 20 to rise and fall inside the device. During the lifting process, the sleeve rod 20 will adjust the angle with the adjusting rod 18 through the third rotating shaft 19 on both sides. Since the length of the adjusting rod 18 is fixed, when the sleeve rod 20 rises, the adjusting rod 18 will drive the second rotating shaft 17 on the right to increase the height, and the second rotating shaft 17 drives the support plate 15 to move upward, and then the support plate 15 will change the angle inside the device, thereby changing the angle of spraying water mist in the air, improving the dust reduction and dust prevention effect, and the adjusting rod 18 will adjust the angle through the second rotating shaft 19 at the end when adjusting the angle. The rotating shaft 17 rotates with the support plate 15 to prevent the adjusting rod 18 and the support plate 15 from being fixed to each other and causing the support plate 15 to be unable to move. At the same time, the third rotating shaft 19 on the other side of the adjusting rod 18 can rotate with the sleeve rod 20 to improve the flexibility of the device during use. Thereafter, during the process of adjusting the angle of the support plate 15, the first rotating shaft 14 on the left and the top plate 11 are rotated to adjust the angle of the water mist sprayed by the device during use, so as to facilitate the reduction of dust in the air during the construction process, reduce dust on the construction site, and prevent dust from being blown into other spaces, thereby playing a dust-proof role. The support plate 15 array is provided with three groups to increase the amount of water mist sprayed into the air.
