The height of the support column 302 can be automatically adjusted according to the position of the sun, and its adjustable height can be automatically adjusted in advance according to time changes to ensure that the solar photovoltaic panel 301 can receive sunlight at the best angle at different times and seasons, thereby improving the efficiency of light energy utilization; effectively reducing the equipment's dependence on external electricity, while also reducing the energy consumption cost of equipment operation, improving the overall environmental protection performance, and fully conforming to the concept of green development of smart cities.

[0027] See attached Figure 8 and attached Fig.11, a small water tank 9 is designed inside the rear body 102 for storing water and providing watering and fertilizing needs during cleaning and greening maintenance. An efficient water pump 7 is installed on the side of the small water tank 9, and the water pump 7 is connected to the filter assembly 8 through a pipeline to achieve the rational use and effective filtration of external water sources, ensuring the cleanliness and safety of water quality. The structure of the filter assembly 8 is exquisitely designed, consisting of an impeller 801, a filter cartridge 805 and a connecting pipe 806. The impeller 801 is the core component of the filtration system, and the middle part is fixedly connected by a high-strength connecting rod 804. The outer side of the connecting rod 804 is rotatably connected to the fixed block 802 to ensure that the impeller 801 maintains efficient rotation during the filtration process, thereby improving the stability of water flow and filtration efficiency. A flexible brush 803 is fixedly connected to the bottom of the connecting rod 804, and the outer side of the brush 803 is close to the inner wall of the filter cartridge 805, which is used to remove sediments and impurities on the inner wall of the filter cartridge 805, ensuring that the filter assembly 8 maintains an efficient working state for a long time. The filter cartridge 805 is the main container of the filtration system. The outer side of the filter cartridge 805 and the outer side of the connecting pipe 806 are designed with a threaded structure. The filter cartridge 805 is tightly connected to the bottom of the connecting pipe 806 through the thread, which is convenient for the disassembly and cleaning of the filter cartridge 805, making the maintenance of the filter assembly 8 more convenient and efficient. In addition, the filter cartridge 805 is made of high-strength corrosion-resistant materials, which can adapt to water quality from different sources and prevent corrosion or blockage problems during the filtration process. The entire filter assembly 8 is used in conjunction with the water pump 7, and water can be drawn from the municipal water supply network or natural water bodies such as rivers or lakes through pipelines, and then transported to the small water tank 9 after filtration. It effectively expands the way to obtain water sources, and also ensures the quality and safety of water sources used in the greening maintenance process, providing reliable guarantees for the precise watering and fertilization functions of road greening maintenance equipment, and also further improves the environmental protection and sustainability of equipment operation.

[0028] Please refer to the attached Figure 8 -Attached Fig.10 , an efficient automatic feeding mechanism 6 is also provided on one side of the small water tank 9, which is used to automatically add fertilizers or drugs to the small water tank 9 in a timely and quantitative manner, so as to achieve precise maintenance of plants in the green belt. The core components of the automatic feeding mechanism 6 include an electric push rod 601 and a material bucket 602. The output end of the electric push rod 601 is fixedly connected to a connecting rod 609, and the other end of the connecting rod 609 is installed with a feeding assembly to ensure that the material can be efficiently transported to the inside of the water tank. The key part of the feeding assembly is the inner cylinder 606. The inner part of the inner cylinder 606 is designed with an external through hole 607. The bottom of the external through hole 607 is fixedly connected to the injection pipe 608. The injection pipe 608 extends into the interior of the small water tank 9, and can evenly disperse the fertilizer or drug into the water source in the water tank; The material hopper 602 is used to store fertilizers or drugs, and a control component is installed at the bottom thereof; the control component consists of an outer cylinder 603, a feed port 604, and a discharge port 605. A feed port 604 is provided at the top of the outer cylinder 603 for fertilizers or drugs to enter the control component from the material hopper 602, and a discharge port 605 is provided at the bottom of the outer cylinder 603, and the fertilizers or drugs are released into the inner cylinder 606 through the discharge port 605. It is worth noting that the positions of the feed port 604 and the discharge port 605 are designed to be on different vertical lines. This layout can effectively control the flow path of the fertilizer or drug and avoid blockage of the material when entering the water tank. The inner cylinder 606 is slidably connected to the inside of the outer cylinder 603, and its sliding direction is controlled by the movement of the electric push rod 601, which can accurately adjust the amount of fertilizer or drug released. The left side of the inner cylinder 606 is designed as a hollow structure to guide the flow of materials, and the aperture of the outer through hole 607 is precisely calculated to meet the size requirements of different fertilizer or drug particles. The aperture is larger than the aperture of the feed port 604, but smaller than the inner diameter of the injection pipe 608, ensuring that the materials can smoothly pass through the outer through hole 607 and enter the injection pipe 608, and finally be transported to the small water tank 9 for mixing; The automatic feeding mechanism 6 realizes the precise delivery of fertilizers or drugs through the automatic control of the electric push rod 601, which not only reduces the complexity of manual operation, but also can flexibly adjust the delivery amount according to actual needs, avoiding waste of resources, so that fertilizers and drugs can be evenly mixed in the water source inside the small water tank 9, providing balanced nutrition supply or drug protection for plants.

[0029] Please refer to the attached Figure 6 -Attached Figure 7 A garbage cleaning mechanism 5 is arranged at the rear side of the rear vehicle body 102, and the garbage cleaning mechanism 5 includes two garbage collecting barrels 501, a support plate 502 and a rotating assembly. The two garbage collecting barrels 501 are installed side by side on the top of the support plate 502, and a flip inner plate 503 is rotatably installed inside the support plate 502 through a rotating shaft 504. A rotating assembly is arranged at the bottom of the support plate 502, and the rotating assembly includes a bottom box 505, and a motor 506 is arranged inside the bottom box 505. A turntable 507 is fixedly connected to the output shaft of the motor 506, and a sliding rod 508 is arranged at the turntable 507 away from the center. A slider 509 is slidably connected to the inside of the bottom box 505, and the sliding rod 508 is slidably connected to the inside of the slider 509. A top rod 510 is fixedly connected to the top of the slider 509; it is used to automatically dump the collected garbage.

[0030] A well-designed garbage cleaning mechanism 5 is installed on the rear side of the rear vehicle body 102, which is used to automatically collect and process the garbage generated during the road cleaning process, and can efficiently realize the automatic dumping function of the garbage. The main structure of the garbage cleaning mechanism 5 includes two garbage collection bins 501, a support plate 502, and a rotating assembly; the two garbage collection bins 501 are arranged side by side and installed on the top of the support plate 502, so as to store garbage from different cleaning areas at the same time and improve the collection efficiency. The garbage collection bin 501 is made of high-strength corrosion-resistant material to ensure its stability and durability during long-term use; The support plate 502 is an important bearing component of the garbage cleaning mechanism 5, and a flip inner plate 503 is rotatably installed inside the support plate 502 through a rotating shaft 504. The flip inner plate 503 can rotate flexibly during the garbage dumping process, thereby driving the garbage collection bin 501 to achieve efficient garbage emptying operation; a rotating assembly is provided at the bottom of the support plate 502, which is used to drive the entire garbage cleaning mechanism 5 to complete the dumping action; the core structure of the rotating assembly is a bottom box 505, and a motor 506 is installed inside the bottom box 505. The motor 506 drives a turntable 507 to rotate through its output shaft, and a slide rod 508 is fixedly installed away from the center. The slide rod 508 is connected to a slider 509 inside the bottom box 505 in a sliding form, and the sliding trajectory of the slider 509 is guided by the rotational movement of the turntable 507, thereby driving the slide rod 508 to slide freely within a limited range. A top rod 510 is also fixedly connected to the top of the slider 509. The function of the top rod 510 is to apply a lifting force to the support plate 502 when the slider 509 slides, so that the flip inner plate 503 drives the garbage collection bin 501 to tilt, thereby realizing automatic dumping of garbage. Through the close cooperation of components such as the rotating shaft 504, the turntable 507, the sliding rod 508, the sliding block 509 and the top rod 510, the garbage cleaning mechanism 5 can achieve a high degree of automation in all aspects of garbage collection and dumping, which not only reduces the need for manual intervention, but also significantly improves the efficiency and accuracy of garbage disposal, and can effectively avoid secondary pollution of equipment or the environment caused by garbage during the dumping process.

[0031] Working principle: The equipment mainly consists of a front body 101 and a rear body 102. The front body 101 is provided with an automatic road cleaning device 2, which cleans the garbage on the road through the roller brush and dust suction device at the bottom of the front side. After cleaning, the garbage is transported to the garbage cleaning mechanism 5 on the rear body 102 through a transmission pipeline. The garbage cleaning mechanism 5 on the rear body 102 includes two garbage collection bins 501. The garbage is collected by the equipment and stored in the garbage collection bins 501. After cleaning, when the garbage bin needs to be dumped, the support plate 502 is driven by the rotating assembly at the bottom to realize automatic dumping of the garbage. The rotating assembly includes a bottom box 505, a motor 506, a turntable 507, and a slider 509 connected to a slide bar 508. The turntable 507 is driven to rotate by the motor 506, and the slide bar 508 moves under the guidance of the slider 509, thereby lifting the support plate 502, so that the flip inner plate 503 drives the garbage bin to tilt, and the garbage is automatically dumped to the designated garbage disposal area. After the garbage is dumped, the slider 509 is reset and the support plate 502 is restored to a horizontal state; While cleaning the road garbage, the greening cleaning mechanism 4 arranged on both sides of the rear body 102 operates synchronously.
