[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a dust suppression tool for highway construction, which has the following beneficial effects:

[0017] 1. Through the drive motor, gear set (first gear, second gear), drive disc, eccentric rod, drive groove and drive rod mechanism, the automatic reciprocating swing of the water pipe and nozzle is realized, which significantly expands the coverage area of ​​water mist spraying, enhances the dust suppression effect, reduces dust dead spots, and improves the quality of the construction environment.

[0018] 2. The system adopts a dual-filter design (first filter and second filter) and a dual-channel design (fixed pipe and water passage). Under normal conditions, water flows through the fixed pipe and the first filter. When the first filter becomes clogged, causing the water pressure to rise, the water pressure pushes the moving plate to compress the moving spring, opening the water passage and the second filter to form a backup flow path. The backup filter channel is automatically activated when the main filter becomes clogged, ensuring that the dust suppression operation is not interrupted and improving the reliability of the equipment.

[0019] 3. When the water pressure continues to rise, the moving plate moves the moving rod to align the first channel with the second channel. Some water flows into the test paper and causes it to change color. The color change of the test paper visually indicates the maintenance needs, enabling preventive maintenance and avoiding complete equipment failure. Attached Figure Description

The fixed rod 14 is provided with a fixed tube 15 and a first filter screen 16. A movable plate 17 is slidably provided between the filter tube 13 and the fixed tube 15. The movable plate 17 is provided with a water passage hole 18 and a second filter screen 19. The drive disk 6 is provided with a rotating shaft 20 on the fixed plate 4. A first gear 21 is provided on the rotating shaft 20. A second gear 22 that cooperates with the first gear 21 is rotatably provided on the fixed plate 4. A fixed frame 23 is provided on the fixed plate 4. A drive motor 24 is provided on the fixed frame 23. The motor shaft of the drive motor 24 is fixedly connected to the second gear 22. A sliding block 25 is provided at the bottom of the movable frame 3. A sliding groove 26 that cooperates with the sliding block 25 is provided on one side of the support plate 2.

[0030] In this embodiment, during use, the water storage tank 1 is placed on a mobile vehicle, and the submersible pump of the water storage tank 1 is connected to the connecting water pipe 11. This structure is existing technology and will not be described in detail here. Water is sprayed through the connecting water pipe 11 and the nozzle 12 to reduce dust at the highway construction site. At the same time, the drive motor 24 is started, which drives the second gear 22 to rotate. The second gear 22 drives the first gear 21 to rotate through gear meshing. The first gear 21 drives the drive disc 6 to rotate through the rotating shaft 20. When the drive disc 6 rotates, it drives the eccentric rod 7 to move in the eccentric groove 9, which in turn drives the drive plate 5 to swing back and forth on the fixed plate 4. Through the cooperation of the drive rod 8 and the drive groove 10, the mobile frame 3 moves back and forth on the support plate 2, and the sliding block 25 moves back and forth on the sliding groove 26, which in turn drives the connecting water pipe 11 and the nozzle 12 to swing back and forth, thereby increasing the spraying area and improving the dust reduction effect.

[0031] Please see Figures 4-5 As one embodiment of the filter tube 13: a movable rod 27 is provided between the fixed rod 14 and the movable plate 17. The movable rod 27 is slidably mounted on the fixed rod 14. One end of the movable rod 27 is fixedly connected to the movable plate 17. A movable spring 28 is provided between the movable plate 17 and the fixed rod 14. A cover plate 29 is detachably provided at the bottom of the filter tube 13. A test paper 30 is provided inside the cover plate 29. A first channel 31 is provided on the fixed rod 14. A second channel 32 is provided between the movable rod 27 and the movable plate 17.

[0032] More specifically, when water flows through the connecting pipe 11, it is filtered through the filter pipe 13. Under normal conditions, the moving plate 17 abuts against the filter pipe 13 under the elastic force of the moving spring 28. The water mainly flows through the fixed pipe 15 on the fixed rod 14 and is filtered through the first filter screen 16. When the first filter screen 16 becomes clogged, the water flow is obstructed, the water pressure increases, and the moving plate 17 and the moving spring 28 are squeezed. This causes the moving plate 17 to drive the moving rod 27 to move towards the fixed rod 14 and squeeze the moving spring 28. The movable plate 17 exposes a water passage hole 18 and a second filter screen 19, which then filter the water, achieving a dual-channel design. When the water pressure increases to a certain level, the movable plate 17 drives the movable rod 27 to move gradually. When the first channel 31 aligns with the second channel 32, some liquid flows onto the test paper 30, causing the test paper 30 to change color, prompting the user to clean and maintain the filter tube 13. The cover plate 29 facilitates the replacement of the test paper 30. The test paper 30 is existing technology, and its working principle will not be described in detail here.

[0033] In summary, during use or operation of the overall equipment: When in use, the water tank 1 is placed on the mobile vehicle, and connected to the water pipe 11 via the submersible pump in the water tank 1. This structure is existing technology and will not be elaborated further. Water is sprayed through the water pipe 11 and the nozzle 12 to reduce dust at the highway construction site. Simultaneously, the drive motor 24 is started, driving the second gear 22 to rotate. The second gear 22, through gear meshing, drives the first gear 21 to rotate. The first gear 21, through the rotating shaft 20, drives the drive disc 6 to rotate. When the drive disc 6 rotates, it drives the eccentric rod 7 to move within the eccentric groove 9, thereby causing the drive plate 5 to reciprocate on the fixed plate 4. Through the cooperation of the drive rod 8 and the drive groove 10, the mobile frame 3 reciprocates on the support plate 2, and the sliding block 25 reciprocates on the sliding groove 26, thereby causing the connecting water pipe 11 and the nozzle 12 to reciprocate, increasing the spraying area and improving the dust reduction effect.

[0034] Simultaneously, as water flows through the connecting water pipe 11, it is filtered through the filter pipe 13. Under normal conditions, the moving plate 17 abuts against the filter pipe 13 under the elastic force of the moving spring 28. The water mainly flows through the fixed pipe 15 on the fixed rod 14 and is filtered through the first filter screen 16. When the first filter screen 16 becomes clogged, the water flow is obstructed, the water pressure increases, and the moving plate 17 and the moving spring 28 are squeezed. This causes the moving plate 17 to drive the moving rod 27 to move towards the fixed rod 14, squeezing the moving spring 28 and moving... The plate 17 exposes a water passage hole 18 and a second filter screen 19, which then filter the water, achieving a dual-channel design. When the water pressure increases to a certain level, the moving plate 17 drives the moving rod 27 to move gradually. When the first channel 31 and the second channel 32 are aligned, some liquid flows onto the test paper 30, causing the test paper 30 to change color, prompting the user to clean and maintain the filter tube 13. The cover plate 29 facilitates the replacement of the test paper 30. The test paper 30 is existing technology, and its working principle will not be described in detail here.
