[0025] The following will disclose multiple embodiments of the present invention with diagrams. For the sake of clear illustration, many physical details will be described together in the following narrative. However, it should be understood that these physical details are not used to limit the present invention. That is to say, in some embodiments of the present invention, these physical details are unnecessary. In addition, for the sake of simplifying the diagrams, some conventional structures and components will be shown in a simple schematic manner in the diagrams.

[0026] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] Please refer to Figures 1 to 6 , the mine dust removal device with spray treatment provided by the present invention includes a base 1 and a silt cleaning component 2, and the silt cleaning component 2 is arranged in the middle of the base 1.

[0028] The silt cleaning component 2 includes an overflow tank 201, a partition plate 202, a slot 203, a silt cleaning spring 204, a plug board 205, a tooth block 206, a rotating slot 207, a ratchet 208, a conveyor belt 209, a bottom plate 210, a fitting spring 211 and a scraping plate 212. An overflow tank 201 is opened in the middle of the base 1, and a partition plate 202 is arranged in the overflow tank 201. Slots 203 are symmetrically opened on both sides of the partition plate 202, and a silt cleaning spring 204 is connected in the slot 203. One end of the silt cleaning spring 204 is connected with a plug board 205, and a tooth block 206 is rotatably connected to one side of the plug board 205 through a spring rotating shaft. A rotating slot 207 is arranged on one side of the slot 203, and a ratchet 208 is rotatably connected in the rotating slot 207. Conveyor belts 209 are symmetrically arranged on both sides of the partition plate 202, and a bottom plate 210 is connected to the surface of the conveyor belt 209. A fitting spring 211 is connected to the inner side of the bottom plate 210, and one end of the fitting spring 211 is connected with a scraping plate 212.

[0029] In some embodiments, the overflow trough 201 is in an inverted V shape, and the partition plates 202 are evenly distributed in the overflow trough 201. The insertion plate 205 is engaged and slidably connected to the partition plate 202 through the slot 203, and the insertion plate 205 is elastically connected to the slot 203 through the dredging spring 204. The insertion plate 205 is engaged and connected to the ratchet wheel 208 through the tooth block 206, and the ratchet wheel 208 is connected to the pulley on one side of the conveyor belt 209. The bottom plates 210 are evenly distributed on the surface of the conveyor belt 209, and the scraping plate 212 is engaged and slidably connected to the bottom plate 210. The scraping plate 212 is elastically connected to the bottom frame through the fitting spring 211, and one end of the scraping plate 212 is in contact with the overflow trough 201. A fitting groove 3 is formed in the middle of the partition plate 202, and a resistance rod 4 is connected in the fitting groove 3. A resistance spring 5 is arranged between the resistance rods 4, and one end of the resistance rod 4 is connected with a backing plate 6. Oblique plates 7 are symmetrically rotatably connected to both sides of the backing plate 6. Air cavities 8 are symmetrically formed on both sides of the partition plate 202, and a plug plate 9 is arranged in the air cavity 8. Both ends of the resistance spring 5 are respectively connected to the partition plate 202 and the backing plate 6, and the backing plate 6 is elastically connected to the partition plate 202 through the resistance spring 5. The insertion plate 205 and the plug plate 9 are both connected to the backing plate 6. Water troughs 10 are arranged on both sides of the overflow trough 201 of the base 1.

[0030] The present invention further provides a baffle 11 in the water trough 10. A filter screen 12 is connected to one side of the baffle 11. Water pumps 13 are arranged on both sides of the base 1, and a water delivery pipe 14 is arranged on one side of the water pump 13. Sewage pumps 15 are arranged on both sides of the base 1, and both the water pumps 13 and the sewage pumps 15 are communicated with the water trough 10 through pipelines. The pipeline connected to the water pump 13 is located above the filter screen 12, and the pipeline connected to the sewage pump 15 is located below the filter screen 12.

[0031] It should be noted that the water mist adsorbed with dust can flow back into the water trough 10 along the inclined surface of the overflow trough 201 after falling onto the overflow trough 201, so as to be recycled. The baffle 11 can prevent sewage from directly flowing above the filter screen 12. The filter screen 12 intercepts impurities in the sewage to ensure that the water entering the water pump 13 is clean water. The impurities in the sewage will precipitate in the water trough 10 until they are pumped out by the sewage pump 15.

[0032] When a vehicle passes by, pressure is applied to the backing plate 6, causing the backing plate 6 to drive the insertion plate 205 to descend within the insertion slot 203, compress the silt cleaning spring 204, and drive the ratchet wheel 208 to rotate within the rotation slot 207 through the tooth block 206. When the ratchet wheel 208 rotates, it can drive the conveyor belt 209 to operate between the partition plates 202, thereby driving the bottom plate 210 to move. When the scraper 212 follows the bottom plate 210 and moves close to the bottom surface of the overflow tank 201, under the action of the fitting spring 211, it closely adheres to the bottom surface of the overflow tank 201, thereby shoveling up the stains accumulated in the overflow tank 201 and carrying them along to move until they are flushed into the water tank 10 together with the wastewater, avoiding the stains from adhering to the inside of the overflow tank 201 and being difficult to clean. At the same time, the resistance rod 4 and the resistance spring 5 can limit the descending distance and the rebound amplitude of the backing plate 6 while ensuring that the backing plate 6 can rebound after the vehicle passes, so that the descending distance of the backing plate 6 is in a corresponding relationship with the vehicle weight;

[0033] Moreover, when the backing plate 6 rebounds and drives the insertion plate 205 to move back, the tooth block 206 can rotate and reset on the insertion plate 205 under the action of the spring rotating shaft, avoiding the tooth block 206 from driving the ratchet wheel 208 to rotate back. When the vehicle passes by, the inclined plate 7 can not only guide the tires, making them smoothly press on the backing plate 6, avoiding damage to the resistance rod 4 due to excessive lateral force on the backing plate 6, but also block the sewage, avoiding the sewage from splashing into the fitting groove 3 and the rotation slot 207; that is, the present invention can automatically clean the overflow tank 201, ensure the cleanliness of the device, and avoid the accumulation of wastewater on the road surface.

[0034] Please refer to Figures 3 to 6 , air grooves 16 are provided on both sides of the base 1, and jacking springs 17 are symmetrically connected within the air grooves 16. One end of the jacking spring 17 is connected to a top plate 18, and the top plate 18 is in snap-fit sliding connection with the base 1 through the air grooves 16. The top plate 18 is elastically connected to the air grooves 16 through the jacking springs 17, and the air grooves 16 are communicated with the air cavity 8. Dust reduction components 19 are provided on both sides of the base 1.

[0035] In some embodiments, the above-mentioned dust reduction component 19 includes branch pipes 1901 symmetrically connected to both sides of the base 1. A valve body 1902 is connected to one side of the branch pipe 1901. Reset springs 1903 are symmetrically connected within the valve body 1902, and one end of the reset spring 1903 is connected to a valve plate 1904. Through holes 1905 are provided on the surface of the valve plate 1904, and the valve plate 1904 is elastically connected to the valve body 1902 through the reset springs 1903. The valve plate 1904 is in snap-fit sliding connection with the valve body 1902, and the branch pipe 1901 is communicated with the water supply pipe 14 through the valve body 1902;

[0036] At the same time, the two sides of the branch pipe 1901 are symmetrically connected with connecting rings 1906, and the connecting rings 1906 are connected with torsion springs 1907, and the inner side of the torsion springs 1907 is connected with swivels 1908, and the nozzles 1909 are connected between the swivels 1908, and one side of the nozzles 1909 is connected with a counterweight rod 1910, and the swivels 1908 are elastically connected to the connecting rings 1906 through the torsion springs 1907, and the swivels 1908 and the connecting rings 1906 are engaged and rotated. The branch pipe 1901 is connected to the nozzle 1909 through the connecting ring 1906 and the rotating ring 1908; the nozzle 1909 is provided with a discharge port 1911 on one side of the counterweight rod 1910, and the other side of the counterweight rod 1910 is snap-connected with an atomizing cover 1912, a shaft rod 1913 is rotatably connected inside the nozzle 1909, and one end of the shaft rod 1913 is connected to an impeller 1914, and scrapers 1915 are symmetrically connected around the shaft rod 1913.

[0037] When a vehicle passes by, as the pad 6 is pressed down by the vehicle, the pad 6 will press the plug plate 9 down in the air cavity 8, and press the air in the air cavity 8 into the air groove 16, thereby pushing the top plate 18 up in the air groove 16 and compressing the lifting spring 17, so that the top plate 18 pushes the valve plate 1904 to move in the valve body 1902 and compresses the return spring 1903, so that the through port 1905 coincides with the passage of the valve body 1902, and the water pump 13 can draw the clean water in the water tank 10 into the water supply pipe 14, and send it into the branch pipe 1901 through the valve body 1902, and then spray it out from the nozzle 1909 through the atomizing cover 1912 to settle the dust stirred up when the vehicle passes, thereby performing dust removal.

[0038] As the weight of the passing vehicle varies, the distance that the pad 6 presses the plug plate 9 to move in the air cavity 8 will also change, thereby causing the top plate 18 to push the valve plate 1904 to move in the valve body 1902. It can be understood that the heavier the vehicle, the larger the overlapping area between the through port 1905 and the passage of the valve body 1902, and the greater the water flow rate.

[0039] When a vehicle passes by, as the pad 6 drives the plug plate 9 to move back, the air in the air groove 16 is drawn back into the air cavity 8, and the top plate 18 can also rebound under the action of the lifting spring 17. At this time, the valve plate 1904 is reset under the action of the reset spring 1903, keeping the through port 1905 and the valve body 1902 staggered, so that the water pump 13 cannot deliver water from the water supply pipe 14 into the nozzle 1909, so as to achieve the effect of spraying and dust reduction only when a vehicle passes by, thereby saving water resources.

[0040] Automatically spray dust suppression when a vehicle passes by, and automatically adjust the spray volume according to the vehicle weight to save water resources. When no spray dust suppression is carried out, there is no water in the spray pipe 1909. Under the action of the counterweight rod 1910 and the torsion spring 1907, the spray pipe 1909 can be inclined at 30° on the branch pipe 1901. 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. The spray pipe 1909 can then rotate downward on the branch pipe 1901 through the swivel ring 1908 and compress the torsion spring 1907. The connecting ring 1906 can limit the spray pipe 1909 through the swivel ring 1908. During the process of the spray pipe 1909 stopping rotating, the torsion spring 1907 will release its elastic potential energy, thereby driving the spray pipe 1909 to rebound. As the spraying continues, the spray pipe 1909 will swing to a certain extent on the branch pipe 1901 until it reaches a balanced state. As the weight of the passing vehicle varies, the change in the water volume entering the spray pipe 1909 will cause the swing amplitude of the spray pipe 1909 to change accordingly, achieving automatic adjustment of the spray range. And during the spraying process, the water flow will drive the shaft rod 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 to clean the inner wall of the spray pipe 1909, removing the dust that enters the spray pipe 1909 through the atomizing cover 1912 and spraying it out with the water mist, preventing dust from adhering to the inner wall of the spray pipe 1909. After the vehicle passes, the residual liquid in the spray pipe 1909 can flow out of the spray pipe 1909 from the drain port 1911, so that it returns to the 30° inclined state. 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 to prevent the drain port 1911 from being blocked.

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

Many modifications and variations are obvious to those of ordinary skill in the art.
