Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5 The utility model provides a technical solution: a dust-proof structure for cold regeneration milling of a road surface, comprising a vehicle body 1 and a connecting plate 2, one side surface of the vehicle body 1 is fixedly connected to the connecting plate 2; a placement box 3 is fixedly connected to a side surface of the connecting plate 2 away from the vehicle body 1, a water tank 4 is fixedly connected to a side surface of the placement box 3 away from the connecting plate 2, a plurality of limit grooves 5 are symmetrically provided on both sides of the surface of the connecting plate 2, a slide groove 6 is provided in the middle of the surface of the connecting plate 2, a water pump 12 is fixedly installed on one side of the top surface of the water tank 4, and a side surface of the water pump 12 is fixedly connected to The water inlet pipe 13 is connected, and the surface of the water inlet pipe 13 on one side away from the water pump 12 is connected to the water tank 4 through the water inlet pipe 13, and the top surface of the water pump 12 is fixedly connected to the water outlet pipe 14; it also includes: buckle components 19 are symmetrically arranged on both sides of the water outlet pipe 14; wherein the buckle component 19 includes a sleeve 1901 fixedly connected to the water outlet pipe 14, and a slide plate 1902 is slidably connected inside the sleeve 1901; wherein a clamping rod 1903 is connected to the middle of the inner part of the slide plate 1902, and a first spring 1904 is sleeved on the surface of the clamping rod 1903, such as Figure 1-4 As shown, by providing the snap assembly 19, the screen 18 can be quickly replaced. At the same time, the screen 18 can also protect the nozzle 16, thereby avoiding damage to the nozzle 16 and increasing the service life of the nozzle.

[0030] One side surface of the first spring 1904 is fixedly connected to the sleeve 1901, and the other side surface of the first spring 1904 is fixedly connected to the slide plate 1902. A sliding rod 1905 is connected to the side surface of the slide plate 1902 near the top, and both sides of the sliding rod 1905 are fixedly connected to the sleeve 1901. A blocking rod 1906 is connected to the middle of the top surface of the sleeve 1901. A second spring 1907 is sleeved on the surface of the blocking rod 1906 near the bottom. The bottom surface of the second spring 1907 is fixedly connected to the sleeve 1901, and the top surface of the second spring 1907 is fixedly connected to the blocking rod 1906. By pulling the card rod 1903, the card rod 1903 can drive the movement of the slide plate 1902. At the same time, after the card rod 1903 is pulled to a certain position, the inclined surface of one side of the slide plate 1902 and the inclined surface of one side of the blocking rod 1906 are fitted together. As the card rod 1903 is continuously pulled, the slide plate 1902 will squeeze the blocking plate, thereby causing the blocking plate to rise, so that the slide plate 1902 continues to slide with the pulling of the card rod 1903. At the same time, when the slide plate 1902 is no longer squeezing the blocking rod 1906, the blocking rod 1906 returns to its original position under the action of the second spring 1907, so that the blocking rod 1906 can limit the slide plate 1902. At the same time, the first spring 1904 and the second spring 1907 are rubber composite springs in the prior art, and the elastic force of the second spring 1907 is greater than the elastic force of the first spring 1904, so that the squeezing of the slide plate 1902 by the first spring 1904 is less than the squeezing of the blocking rod 1906 by the second spring 1907, thereby realizing the limiting of the slide plate 1902 by the blocking rod 1906, making it convenient to quickly disassemble the screen 18.

[0031] An electric push rod 7 is arranged inside the placement box 3, and support rods 8 are fixedly installed on both sides of the electric push rod 7 near the top, and both sides of the support rod 8 are fixedly connected to the placement box 3. The bottom surface of the electric push rod 7 is rotatably connected to a telescopic rod 9, and one side surface of the telescopic rod 9 is rotatably connected to a milling cutter 11. Figure 1 As shown, the model of the electric push rod 7 is LAM33-A, and the milling cutter 11 is one of the parts of the milling device. The operation of the milling cutter 11 is mainly driven by the milling device as a power source.

[0032] The side surface of the water outlet pipe 14 away from the water pump 12 is connected to the placement box 3, the side surface of the water outlet pipe 14 away from the placement box 3 is connected to the limiting sleeve 15, the top surface of the limiting sleeve 15 is fixedly connected to the placement box 3, the bottom surface of the water outlet pipe 14 is connected to a plurality of nozzles 16, the bottom surface of the water outlet pipe 14 is connected to the connecting rod 17 on both sides, and the bottom surface of the connecting rod 17 is fixedly connected to the screen 18, such as Figure 2As shown, the number of the nozzles 16 is not less than seven, and the nozzles 16 can prevent dust, and the screen 18 can prevent broken soil and stones from damaging the nozzles 16, thereby increasing the service life of the nozzles 16.

[0033] A slot 20 is formed on one side of the connecting rod 17 near the top, and the slot 20 is engaged with the connecting rod 1903. Figure 4 As shown, the card slot 20 is engaged with the card rod 1903, so that the connection rod 17 can be better limited.

[0034] The other side surface of the telescopic rod 9 is penetrated with a rotating rod 21, and both sides of the rotating rod 21 are rotatably connected to the push plate 10. Both sides of the push plate 10 are penetrated with a limiting rod 22. A third spring 23 is sleeved on one side surface of the limiting rod 22. A bonding plate 24 is fixedly connected to one side surface of the third spring 23. The other side surface of the third spring 23 is fixedly connected to the push plate 10. The bonding plate 24 is bonded to the connecting plate 2 away from the third spring 23. The bonding plate 24 is penetrated and connected with the limiting rod 22, and the limiting rod 22 is engaged with the limiting groove 5. Figure 5 As shown, by starting the electric push rod 7, the electric push rod 7 can drive the telescopic rod 9 to descend, thereby stretching the telescopic rod 9. At the same time, the rotation between the electric push rod 7 and the telescopic rod 9 is tightened and loosened by the bolts. When it is necessary to adjust the descending height of the milling cutter 11, it is sufficient to loosen the bolts. At the same time, after the limit rod 22 is separated from the limit groove 5 by pulling the limit rod 22, the electric push rod 7 and the telescopic rod 9 are tightened by the bolts, so that the telescopic rod 9 and the milling cutter 11 can be driven to rise, thereby avoiding the occurrence of accidents during transportation. When the milling cutter 11 is in contact with the ground, unnecessary wear of the milling cutter 11 occurs. At the same time, after the milling cutter 11 is separated from the ground, the limit rod 22 is loosened, so that the limit rod 22 is re-engaged with the limit groove 5 under the action of the third spring 23, thereby completing the limiting effect on the telescopic rod 9, thereby increasing the service life of the milling cutter 11. At the same time, the third spring 23 is a compression spring in the prior art. Through the action of the third spring 23, the limit rod 222 can be more tightly engaged with the limit groove 5.

[0035] Working principle: Before using this dust prevention structure for cold regeneration milling of pavement, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, first, when replacing the screen 18, the door installed on one side of the placement box 3 can be opened, and the card rod 1903 can be pulled so that the card rod 1903 can drive the movement of the slide plate 1902. At the same time, after the card rod 1903 is pulled to a certain position, the inclined surface on one side of the slide plate 1902 and the inclined surface on one side of the blocking rod 1906 are fitted together. As the card rod 1903 is continuously pulled, the slide plate 1902 will squeeze the blocking plate, thereby causing the blocking plate to rise, so that the slide plate 1902 continues to slide with the pulling of the card rod 1903, and the slide plate 1902 no longer presses the blocking rod 1906. When 906 is squeezed, the blocking rod 1906 returns to its original position under the action of the second spring 1907, so that the blocking rod 1906 can limit the slide plate 1902. At the same time, the first spring 1904 and the second spring 1907 are rubber composite springs in the prior art, and the elastic force of the second spring 1907 is greater than the elastic force of the first spring 1904, so that the squeezing of the slide plate 1902 by the first spring 1904 is less than the squeezing of the blocking rod 1906 by the second spring 1907, thereby realizing the limiting of the slide plate 1902 by the blocking rod 1906, making it easy to quickly disassemble the screen 18.

[0036] Secondly, by starting the electric push rod 7, the electric push rod 7 can drive the telescopic rod 9 to descend, thereby stretching the telescopic rod 9. At the same time, the rotation between the electric push rod 7 and the telescopic rod 9 is carried out by tightening and loosening the bolts. When it is necessary to adjust the descending height of the milling cutter 11, it is sufficient to loosen the bolts. At the same time, after the limit rod 22 is pulled to separate the limit rod 22 from the limit groove 5, the bolts between the electric push rod 7 and the telescopic rod 9 can be tightened, so that the telescopic rod 9 and the milling cutter 11 can be driven to rise, thereby preventing the milling cutter 11 from contacting the ground during transportation, thereby causing unnecessary wear to the milling cutter 11. At the same time, after the milling cutter 11 is separated from the ground, the limit rod 22 is loosened, so that the limit rod 22 is re-engaged with the limit groove 5 under the action of the third spring 23, thereby completing the limiting effect on the telescopic rod 9, thereby increasing the service life of the milling cutter 11.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
