Preferably, wheels 2 are installed at all four corners of the bottom surface of the body 1 to facilitate the overall movement of the equipment. Each wheel 2 is equipped with brake pads to ensure the stability of the equipment during operation. Furthermore, the body 1 contains a cleaning fluid storage tank 3 for storing cleaning fluid. A pump 4 is connected to the left side wall of the cleaning fluid storage tank 3 to extract the cleaning fluid from the tank. The output end of the pump 4 is connected to a delivery pipe 5, and the other end of the delivery pipe 5 is connected to a nozzle assembly 6. A through groove 19 is formed on the bottom surface of the body 1, and the nozzle assembly 6 is installed within the through groove 19 to spray the cleaning fluid onto the road markings.

[0028] Furthermore, the bottom surface of the machine body 1 is provided with a wastewater recycling tank 7, such as... Figure 2 , Figure 5 and Figure 7 As shown, in this embodiment, the wastewater recovery tank 7 is an annular tank surrounding the nozzle assembly 6, used to collect wastewater after cleaning. A filter screen 8 is installed inside the wastewater recovery tank 7 to filter out impurities in the wastewater, preventing impurities from entering the cleaning fluid storage tank 3 and causing secondary pollution. Furthermore, a vibrator 18 is installed on the left side wall of the filter screen 8, and this vibrator 18 is fixedly installed on the left inner wall of the wastewater recovery tank 7. The vibrator 18 is used to vibrate the filter screen 8 to prevent clogging and ensure the unobstructed flow of the wastewater recovery tank 7. Furthermore, a recovery pipe 9 is connected to the right side wall of the wastewater recovery tank 7. The other end of the recovery pipe 9 passes through the right side wall of the machine body 1 and connects to the cleaning fluid storage tank 3 (through a return pump), realizing the recycling of the cleaning fluid, saving water resources, and reducing environmental pollution.

[0029] Furthermore, such as Figures 1 to 7 As shown, a mounting bracket 10 is provided on the front wall of the machine body 1, and a drive motor 11 is installed inside the mounting bracket 10. A control switch 17 is installed on the front wall of the machine body 1, and the control switch 17 is electrically connected to the liquid pump 4, the drive motor 11, and the vibrator 18, so as to facilitate the operator to control the working status of the liquid pump 4, the drive motor 11, and the vibrator 18. The output end of the drive motor 11 is provided with a rotating shaft 12, and the other end of the rotating shaft 12 is provided with a threaded rod 13. A slider 14 is threadedly connected to the outer wall of the threaded rod 13. When the drive motor 11 is started, the drive motor 11 drives the rotating shaft 12 to rotate, the rotating shaft 12 drives the threaded rod 13 to rotate, and the threaded rod 13 drives the slider 14 to move on the threaded rod 13.

[0030] Specifically, such as Figures 1 to 7As shown, a fixing plate 15 is fixedly installed on the bottom surface of the slider 14, and a modular cleaning component 16 is installed on the bottom surface of the fixing plate 15. The modular cleaning component 16 is used to clean the road markings. The modular cleaning component 16 includes a mounting frame 1601, and a cleaning brush 1602 is provided on the bottom surface of the mounting frame 1601 (of course, the cleaning brush 1602 is preferably rotatably mounted on the bottom surface of the mounting frame 1601 with its own drive, and the cleaning brush 1602 is driven to rotate for brushing, which results in a better brushing effect). The top surface of the cleaning brush 1602 is evenly provided with bristles 1603, and the bottom surface of the cleaning brush 1602 is designed with a wavy structure, which increases the contact area and friction between the cleaning brush 1602 and the road markings, thereby improving the cleaning effect. Both sides of the mounting frame 1601 are provided with sliding grooves 1604, and a locking block 1605 is provided in the sliding groove 1604. The other end of the locking block 1605 passes through the sliding groove 1604 and engages with the locking slot 1501 opened in the bottom surface of the fixing plate 15. Through the cooperation of the sliding groove 1604 and the locking block 1605, the modular cleaning component 16 can be easily installed and disassembled, improving the maintenance convenience of the cleaning machine. Further optimized, springs 1606 are installed at the four corners of the top surface of the mounting frame 1601, and the other end of the springs 1606 is installed on the bottom surface of the fixing plate 15. The springs 1606 are used to buffer the modular cleaning component 16, preventing damage caused by hard contact between the modular cleaning component 16 and the road surface during operation. Through the cooperation of the threaded rod 13 and the slider 14, the height and position of the modular cleaning component 16 can be easily adjusted, and the quick replacement of the modular cleaning component 16 can be achieved, improving the efficiency and maintenance convenience of the cleaning machine.

[0031] In summary, this road marking cleaning machine, by incorporating a cleaning fluid storage tank 3, a pump 4, a delivery pipe 5, a nozzle assembly 6, a wastewater recovery tank 7, a filter screen 8, and a recovery pipe 9, achieves the recycling of cleaning fluid, saving water resources and reducing environmental pollution. The inclusion of a filter screen 8 and a vibrator 18 prevents clogging of the filter screen 8 and ensures the unobstructed flow of the wastewater recovery tank 7. The installation of a mounting frame 10, a drive motor 11, a rotating shaft 12, a threaded rod 13, a slider 14, a fixing plate 15, and a modular cleaning assembly 16 enables rapid replacement of the modular cleaning assembly 16, improving the machine's efficiency and ease of maintenance. The inclusion of a spring 1606 buffers the modular cleaning assembly 16, preventing damage from hard contact with the road surface during operation. This invention features a reasonable structural design, is easy to use, and solves the problems of cleaning fluid waste, environmental pollution, and difficulty in replacing cleaning components found in traditional road marking cleaning machines, demonstrating high practical value.

[0032] To further improve the cleaning effect of this road marking cleaning machine, and considering that the modular cleaning component 16 is a crucial part for achieving this effect, optimization of the modular cleaning component 16 is necessary. This embodiment is an improvement upon the previous embodiment. Specifically, a high-pressure nozzle can be added to the modular cleaning component 16. The high-pressure nozzle is connected to the output end of the liquid pump 4, allowing the cleaning fluid to be sprayed onto the road markings at high pressure, thus enhancing the cleaning effect. Simultaneously, to further improve the mobility and stability of the equipment, telescopic outriggers 20 can be added to the bottom surface of the machine body 1. The telescopic outriggers 20 can be extended and retracted as needed to adjust their height, making the equipment more stable during operation.

[0033] In addition, to further improve the intelligence of the equipment, sensors and control modules can be added to the main body 1. The sensors are used to detect the degree of dirtiness and cleaning effect of the road markings, and the control module automatically adjusts parameters such as the spray volume of cleaning fluid and the rotation speed of the cleaning brush 1602 according to the detection results of the sensors to achieve a more precise cleaning effect.

[0034] This utility model provides a road marking cleaning machine that, through reasonable design and optimization, achieves functions such as the recycling of cleaning fluid, rapid replacement of modular cleaning components, and intelligent cleaning control. It solves the problems existing in traditional road marking cleaning machines and has high practical value. It is hoped that those skilled in the art will fully understand the technical solution of this utility model and, based on this, conduct further innovation and development, making a greater contribution to road maintenance.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
