[0002] Construction site dust is a significant source of inhalable particulate matter pollution in urban areas and a major concern for residents regarding air pollution. During construction, dust is inevitably generated due to the mixing of building materials, the movement of vehicles, and the movement of people. Currently, the main method for controlling construction site dust is to spray water using water pumps connected to water pipes.
[0003] Existing dust control devices for construction projects mainly use a single spray gun for spraying, and the spray angle of the water pipe is fixed, which cannot meet the actual needs of use. Therefore, dust control devices for construction projects still have some shortcomings and need further improvement.
[0004] To address these shortcomings, a dust control device for engineering construction is proposed, which is upgraded and modified based on the existing device. Utility Model Content
[0005] The purpose of this utility model is to provide a dust control device for engineering construction in order to solve the problems in the background technology.

[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses a water pump to deliver water from the water tank to the sprayer through the outlet pipe, which facilitates dust control at the construction site. The first motor drives the threaded rod to rotate, causing the moving plate to move up or down, which facilitates the adjustment of the sprayer's height. The second motor drives the screw rod to rotate, causing the push rod to move upward, which facilitates the adjustment of the angle between the sprayer and the fixed block, thereby improving the dust control effect at the construction site.
[0015] 2.

[0025] like Figures 1 to 4As shown, a dust control device for construction projects includes a trolley 1. A water tank 16 is fixedly installed on the left side of the upper surface of the trolley 1. A handle 18 is rotatably connected to the upper left end of the water tank 16. A fixing mechanism 2 is provided inside the water tank 16. A support plate 11 is fixedly installed on the right side of the upper surface of the trolley 1. A motor 111 is fixedly installed on the bottom of the inner wall of the support plate 11. A threaded rod 114 is fixedly installed on the output shaft of the motor 111. A movable plate 12 is threadedly connected to the upper outer end of the threaded rod 114. Fixing blocks 15 are fixedly connected to both sides of the upper end of the movable plate 12. The inner side of the fixing blocks 15... A sprayer 13 is rotatably connected. A water pump 10 is fixedly installed on the upper end of the trolley 1. The water inlet of the water pump 10 is connected to the bottom of the inner wall of the water tank 16. A water outlet pipe 14 is fixedly installed on the upper end of the water pump 10. One end of the water outlet pipe 14 is fixedly installed on the upper end of the sprayer 13. A motor 134 is fixedly installed on the inner wall of the upper end of the moving plate 12. A screw rod 133 is fixedly installed on the output shaft of the motor 134. A push rod 132 is threadedly connected to the outer end of the screw rod 133. A sliding plate 131 is rotatably connected to the upper end of the push rod 132. The upper end of the sliding plate 131 is slidably connected to the bottom of the sprayer 13.
[0026] Specifically, by starting the water pump 10, water from the water tank 16 is delivered to the sprayer 13 through the outlet pipe 14, facilitating dust control at the construction site. By starting the motor 111, the threaded rod 114 is rotated, causing the moving plate 12 to move up or down, facilitating the adjustment of the height of the sprayer 13 and making it easier to remove dust from higher areas. By starting the motor 134, the screw rod 133 is rotated, causing the push rod 132 to move upward, facilitating the adjustment of the angle between the sprayer 13 and the fixed block 15, making it easier to adjust to a suitable angle for better dust removal.
[0027] like Figure 1 As shown, a water inlet 17 is fixedly installed at the upper end of the water tank 16, and a water inlet pipe is fixedly installed on the upper side of the outer end of the water tank 16. Specifically, the water inlet 17 facilitates the addition of water to the inside of the water tank 16, and the water inlet pipe facilitates the direct connection of an external water pipe, so that the external water pipe can continuously supply water to the water tank 16, making it possible for the device to be used continuously.
[0028] like Figure 1 and Figure 2 As shown, a guide rod 112 is slidably connected to the inner wall of the movable plate 12. The lower end of the guide rod 112 extends out of the movable plate 12 and is fixedly installed on the inner wall of the support plate 11. A stop block 113 is fixedly installed on the upper end of the guide rod 112. Specifically, this facilitates the stable movement of the movable plate 12.
[0029] like Figure 1 and Figure 4As shown, a guide block 135 is fixedly connected to the outer end of the push rod 132, and a guide groove 136 is provided on the inner wall of the moving plate 12 for the outer end of the guide block 135 to slide and connect; specifically, this facilitates the stable movement of the push rod 132.
[0030] like Figure 1 and Figure 3 As shown, the fixing mechanism 2 includes a protrusion 21. The end of the handle 18 near the water tank 16 is fixedly connected to the protrusion 21. The lower end of the protrusion 21 abuts against a pressure block 22. The lower end of the pressure block 22 is fixedly installed with a transmission rod 24. The outer end of the transmission rod 24 is slidably connected to the inner wall of the water tank 16. The end of the transmission rod 24 away from the pressure block 22 is fixedly installed with an anti-slip block 25. The lower end of the anti-slip block 25 extends out of the trolley 1. Elastic blocks 23 are fixedly installed on both sides of the lower end of the pressure block 22. The lower end of the elastic blocks 23 is fixedly installed to the inner wall of the water tank 16. Specifically, by rotating the handle 18 upward, the protrusion 21 squeezes the pressure block 22, causing the transmission rod 24 to drive the anti-slip block 25 downward, so that the anti-slip block 25 contacts the ground, fixing the trolley 1 to the ground. Conversely, by rotating the handle 18 back to its original position, the anti-slip block 25 can return to its original position through the action of the elastic blocks 23, making the device movable.
[0031] In summary: the water inlet 17 facilitates the addition of water to the water tank 16; the water pump 10 delivers water from the water tank 16 to the sprayer 13 through the outlet pipe 14, facilitating dust control at the construction site; the motor 111 drives the threaded rod 114 to rotate, causing the moving plate 12 to move up or down, allowing for height adjustment of the sprayer 13 and facilitating dust removal at higher elevations; the motor 134 drives the screw rod 133 to rotate, causing the push rod 132 to move upward, allowing for angle adjustment between the sprayer 13 and the fixed block 15, ensuring a suitable angle for improved dust removal efficiency.
[0032] By rotating the handle 18 upwards, the protrusion 21 presses against the pressure block 22, causing the transmission rod 24 to drive the anti-slide block 25 downwards, so that the anti-slide block 25 contacts the ground and fixes the trolley 1 on the ground. Conversely, by rotating the handle 18 back to its original position, the anti-slide block 25 can return to its original position through the action of the elastic block 23, making it easy for the device to move.
[0033] If the external water pipe can be directly connected to the inlet pipe, so that the external water pipe can continuously supply water to the water tank 16, the device can be used continuously.
