[0034] Please refer to Figures 3 to 6 The base 1 is provided with air grooves 16 on both sides, the air grooves 16 are symmetrically connected with jacking springs 17, one end of the jacking springs 17 is connected with top plates 18, the top plates 18 are slidably connected with the base 1 through the air grooves 16, the top plates 18 are elastically connected with the air grooves 16 through the jacking springs 17, the air grooves 16 are communicated with the air cavities 8, and dust removal assemblies 19 are arranged on both sides of the base 1.

[0035] In some embodiments, the dust removal assembly 19 includes branch pipes 1901 symmetrically connected to both sides of the base 1, one side of the branch pipe 1901 is connected with a valve body 1902, the valve body 1902 is symmetrically connected with return springs 1903, one end of the return springs 1903 is connected with valve plates 1904, the valve plates 1904 are provided with through holes 1905, the valve plates 1904 are elastically connected with the valve body 1902 through the return springs 1903, the valve plates 1904 are slidably connected with the valve body 1902, and the branch pipe 1901 is communicated with the water supply pipe 14 through the valve body 1902;

[0036] Meanwhile, the branch pipe 1901 is symmetrically connected with connecting rings 1906 on both sides, the torsional springs 1907 are connected in the connecting rings 1906, the rotating rings 1908 are connected on the inner sides of the torsional springs 1907, the spray pipes 1909 are connected between the rotating rings 1908, the counterweight rods 1910 are connected on one side of the spray pipes 1909, the rotating rings 1908 are elastically connected with the connecting rings 1906 through the torsional springs 1907, the rotating rings 1908 are rotatably connected with the connecting rings 1906 in a clamping mode, and the branch pipe 1901 is communicated with the spray pipes 1909 through the connecting rings 1906 and the rotating rings 1908; the liquid discharge ports 1911 are formed in the spray pipes 1909 on one side of the counterweight rods 1910, the atomizing covers 1912 are clampingly connected on the other side of the counterweight rods 1910, the shaft rods 1913 are rotatably connected in the spray pipes 1909, the impellers 1914 are connected on one end of the shaft rods 1913, and the scraping strips 1915 are symmetrically connected around the shaft rods 1913.

[0037] When the vehicle passes, the cushion plate 6 is pressed down by the vehicle, the cushion plate 6 drives the plug plate 9 to descend in the air cavity 8, the air in the air cavity 8 is pressed into the air groove 16, the top plate 18 is driven to ascend in the air groove 16 and compresses the jacking spring 17, the valve plate 1904 is driven to move in the valve body 1902 and compresses the reset spring 1903, the through port 1905 is coincided with the passage of the valve body 1902, the water pump 13 can pump the clean water in the water tank 10 into the water delivery pipe 14, and then into the branch pipe 1901 through the valve body 1902, and then sprayed out through the atomizing covers 1912 from the spray pipes 1909, so that the dust caused by the passing vehicle is settled, and the dust removal work is performed.

[0038] With the different weights of the passing vehicles, the distance that the cushion plate 6 drives the plug plate 9 to move in the air cavity 8 changes, so that the distance that the top plate 18 drives the valve plate 1904 to move in the valve body 1902 changes; it can be understood that the heavier the vehicle is, the larger the coincided area of the through port 1905 and the passage of the valve body 1902 is, and the larger the water passing amount is.

[0039] After the vehicle passes, the air in the air groove 16 is drawn back into the air cavity 8 with the return of the cushion plate 6 and the plug plate 9, the top plate 18 can also rebound under the action of the jacking spring 17, the valve plate 1904 is reset under the action of the reset spring 1903, the through port 1905 is kept misaligned with the passage of the valve body 1902, the water pump 13 cannot send water from the water delivery pipe 14 into the spray pipes 1909, and the effect that the spraying and dust setting are performed only when the vehicle passes is achieved, and the water resource is saved.

[0040] When the vehicle passes, the spraying and dust reduction is automatically carried out, and the spraying amount is automatically adjusted according to the weight of the vehicle, thereby saving water resources. When the spraying and dust reduction is not carried out, the water is not in the spray pipe 1909, and the spray pipe 1909 can be inclined at 30° on the branch pipe 1901 under the action of the counterweight rod 1910 and the torsional spring 1907. When spraying, after the water flow enters the spray pipe 1909, the center of gravity of the spray pipe 1909 and the counterweight rod 1910 changes rapidly, and the spray pipe 1909 can be rotated downward on the branch pipe 1901 through the rotating ring 1908, and the torsional spring 1907 is compressed. The connecting ring 1906 can limit the spray pipe 1909 through the rotating ring 1908, and in the process of stopping the rotation of the spray pipe 1909, the torsional spring 1907 releases its elastic potential energy, thereby driving the spray pipe 1909 to rebound. With the continuous spraying, the spray pipe 1909 will swing to a certain extent on the branch pipe 1901 until it reaches an equilibrium state. With the change of the water amount entering the spray pipe 1909 with the weight of the passing vehicle, the swing amplitude of the spray pipe 1909 changes accordingly, achieving automatic adjustment of the spraying range. During the spraying process, the water flow drives the shaft 1913 to rotate in the spray pipe 1909 through the impeller 1914, thereby driving the scraping strip 1915 to move in the spray pipe 1909, cleaning the inner wall of the spray pipe 1909, and clearly removing the dust entering the spray pipe 1909 through the atomizing cover 1912 and spraying it out with the water mist, avoiding the dust adhering to the inner wall of the spray pipe 1909. After the vehicle passes, the residual water in the spray pipe 1909 can flow out of the spray pipe 1909 from the drain port 1911, thereby restoring the spray pipe 1909 to the state of 30° inclination. When the water flow enters the spray pipe 1909, the rapidly entering water flow can also flush out the dust at the drain port 1911, avoiding the blockage of the drain port 1911.

[0041] In summary, during the spraying process, the spraying angle can be automatically changed according to the weight of the vehicle, thereby adjusting the spraying range, and self-cleaning is carried out during spraying.
