[0026] Referring to Figure 1 and Figure 5A motor 3 is installed on the upper surface of the storage tank 2. As the device continues to operate, the asphalt inside the storage tank 2 may precipitate. At this time, the motor 3 is started. A rotating rod 19 is fixedly connected to the output end of the motor 3. The motor 3 drives the rotating rod 19 to rotate. An agitator 20 is fixedly connected to the outer wall of the rotating rod 19. The agitator 20 on the rotating rod 19 will agitate the emulsified asphalt in the storage tank 2, effectively preventing the emulsified asphalt from settling and separating, and ensuring its uniformity. A connecting ring 21 is fixedly connected to the outer wall of the rotating rod 19. At the same time, the connecting ring 21 will also rotate with the rotating rod 19.

[0027] Working principle: First, emulsified asphalt is injected into storage tank 2 through feed pipe 18. Then, water pump 5 is started. Water pump 5 draws emulsified asphalt from storage tank 2 through connecting pipe 4 and then delivers it to atomizing nozzle 7 through output pipe 6. During the transportation of emulsified asphalt, filter plate 9 in connecting pipe 4 filters impurities in emulsified asphalt. At the same time, under the pressure of water pump 5, emulsified asphalt is sprayed out from atomizing nozzle 7, forming an atomized state and evenly sprinkled on asphalt pavement, thereby realizing the maintenance operation of pavement.

[0028] When the filter plate 9 needs to be cleaned or replaced, the pull plate 13 can be pulled first. The pull plate 13 can drive the locking rod 15 to move outward, so that it can be disengaged from the locking groove 12. At the same time, the spring 17 on its outer wall will also be squeezed and contracted by the connecting block 16 until the locking rod 15 is completely disengaged from the locking groove 12. Through the sliding cooperation between the slide bar 10 and the inner wall of the connecting box 8, the filter plate 9 can be pulled out from the connecting box 8, thus realizing the convenient disassembly and cleaning of the filter plate 9. After cleaning or replacing the filter plate 9, the filter plate 9 can be reinserted into the connecting box 8. At this time, the pull plate 13 can be released. Through the elasticity of the spring 17, the locking rod 15 can be re-locked into the locking groove 12, thus realizing the convenient installation of the filter plate 9.

[0029] As the device continues to operate, the asphalt inside storage tank 2 may experience sedimentation. At this time, the motor 3 is started, driving the rotating rod 19 to rotate. The stirring blades 20 on the rotating rod 19 then stir the emulsified asphalt inside storage tank 2, effectively preventing sedimentation and stratification, and ensuring its uniformity. Simultaneously, the connecting ring 21 also rotates with the rotating rod 19, which in turn drives the scraper 23 on its outer side to rotate. The scraper 23 scrapes away any residual emulsified asphalt on the inner wall of storage tank 2, ensuring full utilization of the emulsified asphalt and effectively avoiding waste.
