Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction in road construction, specifically a dust reducer for road construction. Background Technique

[0002] During the process of road construction, a large amount of dust will be generated. The dust fills the air, which is likely to cause environmental pollution and also affects the lung health of people. Particular attention should be paid to dust protection during construction in urban areas and places with a large flow of people. Therefore, dust reduction treatment is required.

[0003] As in the prior art, the publication number (CN220565126U) discloses a dust reducer for road construction. By setting a water tank, a water pump, a water pipe and a nozzle, it can spray the road construction road surface, thereby realizing the mobile dust reduction work of the whole device, increasing the convenience and practicability of the device. At the same time, by setting a driving component and a lead screw component, the height of the nozzle can be adjusted, so as to be applicable to different road construction spraying and dust reduction work, and the application range of the whole device is increased. However, the prior art cannot automatically adjust the angle during the spraying process of the nozzle, and thus cannot automatically adjust the spraying direction of the nozzle, reducing the flexibility of the nozzle spraying. Therefore, there is still room for improvement in the prior art. Content of the Utility Model

[0018] The technical solution of this patent will be further described in detail below in conjunction with the specific implementation manner.

[0019] Please refer to Figures 1 - 5 , a road construction dust suppressor, including a moving seat 1; a water tank 4 is installed on the moving seat 1, the water tank 4 is connected to a water pipe 6, the water pipe 6 is sequentially connected to a water pump 5 and a mounting seat 7, a handle 8 is arranged on the mounting seat 7, a lifting cylinder 2 is installed on the moving seat 1, the lifting cylinder 2 is fixedly connected to a mounting frame 3, positioning components are arranged on both sides of the mounting frame 3 for positioning the mounting seat 7, two symmetrically distributed brackets 14 are arranged on the outer wall of the mounting seat 7, a rotating shaft 15 is rotatably arranged on the bracket 14, a V-shaped plate 16 is rotatably arranged on the rotating shaft 15, a counterweight 21 is installed at the bottom end of the V-shaped plate 16, a limiting rod 20 is installed on the outer wall of the bracket 14, a diverging chamber 18 is arranged on the upper surface of the V-shaped plate 16, a plurality of sprinkler heads 19 are arranged in the diverging chamber 18, the diverging chamber 18 is connected to the water pipe 6 through a delivery pipe 17, a jacking component in contact with the V-shaped plate 16 is arranged on the bracket 14, an attracting component is arranged on the jacking component, the attracting component is used to drive the jacking component, and the jacking component is used to jack the V-shaped plate 16 to rotate.

[0020] Move the moving seat 1 to the part where dust suppression is required, fix the mounting seat 7 on the mounting frame 3 through the positioning component, and adjust the spraying height of the nozzle 19 through the lifting cylinder 2. Start the water pump 5, extract the water in the water tank 4, and transport it to the delivery pipe 17 through the water pipe 6. The delivery pipe 17 then transports it into the diversion cavity 18. There are multiple water flow channels in the diversion cavity 18, so that the water flow can be ejected from multiple nozzles 19 to achieve large-area spraying and dust suppression. Moreover, the directions of the water flow channels in multiple diversion cavities 18 are all different, and the spraying directions of multiple nozzles 19 are also all different. When the water in the delivery pipe 17 is transported into the diversion cavity 18, the V-shaped plate 16 will be pushed to rotate counterclockwise due to the impact force of the water flow, causing the V-shaped plate 16 to move away from the limiting rod 20 and squeeze the pushing component. When the V-shaped plate 16 rotates a certain angle, the attracting component is activated, causing the pushing component to reset, thereby pushing the V-shaped plate 16 back to the initial position, that is, the position where the V-shaped plate 16 contacts the limiting rod 20. Repeating the above operations can achieve the free adjustment of the angle of the V-shaped plate 16, that is, the spraying angle can be automatically adjusted during the spraying process of the nozzle 19, improving the flexibility of the spraying of the nozzle 19.

[0021] The positioning component includes positioning grooves 10 opened on both sides of the mounting seat 7. Moving rods 11 are slidably arranged on both sides of the mounting frame 3. The moving rods 11 are T-shaped. A positioning block 13 that cooperates with the positioning groove 10 is installed at one end of the moving rod 11 close to the middle of the mounting frame 3. A first spring 12 connected to the mounting frame 3 is arranged at the end of the moving rod 11 away from the positioning block 13. During use, the moving rod 11 can be pulled, and then the mounting seat 7 is placed into the mounting frame 3. After releasing the moving rod 11, under the action of the first spring 12, the positioning rod automatically inserts into the positioning grooves 10 on both sides of the mounting seat 7 to achieve the fixation of the mounting seat 7. The nozzle 19 can be used flexibly in a detachable manner. It is also possible to hold the mounting seat 7 by the handle 8 for spraying and dust suppression, or to perform spraying by being installed on the mounting frame 3. The use is relatively flexible.

[0022] Two symmetrically distributed limiting grooves 9 that can be slidably connected to the bottom of the mounting seat 7 are opened at the bottom of the mounting frame 3. When the mounting seat 7 and the mounting frame 3 are connected, by making the mounting seat 7 slidably connected to the limiting grooves 9, the mounting seat 7 can be more accurately placed into the mounting frame 3, facilitating the positioning component to position it.

[0023] The pushing component includes two ejector rods 22 slidably connected to the bracket 14. A bottom plate 23 is installed at the bottom of the ejector rod 22. A second spring 24 is arranged between the bottom plate 23 and the bracket 14. Under the action of the second spring 24, the ejector rod 22 contacts the bottom wall of the V-shaped plate 16.

[0024] The attracting component includes an electromagnet 25 disposed on the bracket 14 and the proximal end of the bottom plate 23, and a distance sensor 26 is disposed on the bottom plate 23.

[0025] When the water in the conveying pipe 17 is conveyed into the shunt chamber 18, the impact force of the water flow will push the V-shaped plate 16 to rotate counterclockwise, causing the V-shaped plate 16 to move away from the limiting rod 20 and squeezing the ejector rod 22, causing the ejector rod 22 to move downward. When the V-shaped plate 16 rotates a certain angle and the distance sensor 26 detects that the distance between it and the bracket 14 reaches the set value, a signal will be sent, and at the same time, the electromagnet 25 starts to be energized to generate magnetism. The bottom plate 23 moves upward through the attraction between the electromagnets 25, causing the ejector rod 22 to start pushing the V-shaped plate 16 to rotate clockwise, causing the ejector rod 22 to reset, thereby pushing the V-shaped plate 16 back to the initial position, that is, the position where the V-shaped plate 16 contacts the limiting rod 20. Repeating the above operations can realize the free adjustment of the angle of the V-shaped plate 16, that is, the spraying angle can be automatically adjusted during the spraying process of the nozzle 19, improving the flexibility of the spraying of the nozzle 19.

[0026] In the present utility model, the water flow conveyed through the water pipe 6 forms an impact force on the shunt chamber 18 of the V-shaped plate 16, thereby causing the V-shaped plate 16 to rotate counterclockwise. When the V-shaped plate 16 rotates a certain angle, the attracting component will be activated, thereby driving the ejecting component to push the V-shaped plate 16, causing the V-shaped plate 16 to reset. Repeating the above operations can realize the automatic adjustment of the angle of the V-shaped plate 16, that is, the spraying angle can be automatically adjusted during the spraying process of the nozzle 19, improving the flexibility of the spraying of the nozzle 19.
