The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an integral connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1

[0032] Please see Figure 1-13 This invention provides a technical solution comprising a track 53, characterized in that: a supporting base plate 4 is provided on the upper surface of the track 53, and a track surface 2 is provided on the surface of the track 53; the supporting base plate 4 bears the weight; track cleaning plates 6 are respectively provided on the left and right sides of the upper surface of the supporting base plate 4; seven large spray nozzles 10 are equidistantly arranged at the front end of the track cleaning plates 6, and eight small spray nozzles 9 are equidistantly arranged at the rear end of the track cleaning plates 6; a valve a7 is provided in the center of the upper surface of the supporting base plate 4; thirty water supply pipes 8 are provided on the side of the valve a7; the valve a7 is groovedly connected to the water supply pipes 8; the small spray nozzles 9 are fixedly connected to the water supply pipes 8; the large spray nozzles 10 are fixedly connected to the water supply pipes 8; a water tank 11 is welded to the upper surface of the valve a7; when the valve a7 is opened, water in the water tank 11 enters the small spray nozzles 9 and large spray nozzles 10 through the water supply pipes 8 and flows out, hitting the track surface 2 and washing away the residue adhering to the track surface 2. The soil is removed and returned to the ground, completing the self-cleaning of the track 53 and preventing soil from being trapped on the track surface 2, causing secondary pollution to the working surface. The front and rear ends of the track surface 2 are respectively equipped with drive wheels 5 and idler wheels 1. The drive wheels 5 and idler wheels 1 are staggered and cross each other in the longitudinal direction of the support base plate 4. Two step motors 3 are set at the bottom of the support base plate 4. When the central controller 56 receives the target command from the environmental perception and decision module 57, it immediately sends a path planning command to the motion control module 58, thereby driving the step motors 3 to output rotational torque. The step motors 3 directly drive the drive wheels 5 to rotate through a key connection with the drive wheels 5. The teeth of the drive wheels 5 precisely mesh with the meshing holes of the track surface 2. With the help of friction and meshing force, the entire track 53 is driven to move. The idler wheels 1 guide and cooperate with the track 53, applying pretension to the track 53, guiding the track 53 to wind smoothly, and propelling the track 53 to move steadily.

[0033] Furthermore, a valve b13 is provided on the upper surface of the water tank 11. A connecting pipe 16 is fixedly connected to the rear end of the valve b13, and a water pump 12 is fixedly connected to the rear end of the connecting pipe 16. The water pump 12 draws water from the water tank 11 and enters the valve b13 through the connecting pipe 16. Spray arm water supply pipes 14 are respectively connected to the left and right sides of the center of the upper surface of the valve b13, and an upper water pipe 15 is connected to the upper surface of the valve b13. Water flows from the valve b13 into the spray arm water supply pipe 14. The spray arm water supply pipe 14 is connected to the mechanical arm water inlet 17-1 on the hollow shaft rotary joint 17. Water flows from the spray arm water supply pipe 14 into the machine arm. The robotic arm has a water inlet 17-1, which is connected to a cylindrical servo motor 17-2. The cylindrical servo motor 17-2 receives electrical signals from the motion control module 58 and outputs rotational motion. Bearings 18 are installed on both sides of the cylindrical servo motor 17-2, providing stable radial support for the entire rotation axis. The bearings 18 are connected to a reducer 19. The cylindrical servo motor 17-2 is connected to the robotic arm 20. The reducer 19 outputs the rotation of the rotation axis, driving the rotation of the robotic arm 20. A robotic arm shaft connector 20-1 is installed on the robotic arm 20. Robotic arm fasteners 21 are provided on both sides of the spray arm 27. An angle rotation shaft 25 is provided on the outer side of the robotic arm fasteners 21. A robotic arm shaft connector 20-1 is welded to the angle rotation shaft 25. A rubber hose 30 is connected to the center of the robotic arm connector 20-1. The angle rotation shaft 25 is connected to a small cylindrical servo motor 22 and a cylindrical pin 24. Spray arm fasteners 23 are provided on both sides of the cylindrical pin 24. The cylindrical pin 24 is connected to a spray arm connecting groove 26. The spray arm connecting groove 26 is keyed to the spray arm 27. The spray arm fasteners 23 fix the cylindrical pin 24 from both sides. Four set screws 31 are equidistantly arranged on the connecting groove 26. The set screws 31 lock the spray arm connecting groove 26 and the spray arm 27 together. The spray arm fastener 23 rigidly fixes the angle rotation shaft 25 and the spray arm connecting groove 26 together from both sides of the spray arm connecting groove 26, forming a rigid structure with an adjustable rotation angle. When the small cylindrical servo motor 22 is started, its output drives the angle rotation shaft 25 to rotate. The angle rotation shaft 25 synchronously drives the mechanical arm shaft connector 20-1 and the spray arm connecting groove 26 welded to it to rotate around the axis. Six central spray nozzles 29 are equidistantly arranged on both sides of the spray arm 27.

[0034] Furthermore, a spray claw 28 is provided at the top of the spray arm 27. The spray claw 28 includes a spray claw outlet 28-1 and a spray claw surface 28-2. A valve c32 is provided in the center of the spray claw 28. The two ends of the rubber hose 30 are connected to the robotic arm shaft connector 20-1 and the spray arm connecting groove 26, respectively. When the angle rotation shaft 25 starts to rotate, the rubber hose 30 can form a safety buffer structure. After water flows in from the robotic arm inlet 17-1, it exits through the central cavity of the cylindrical servo motor 17-2. The water passes through the cavity of the robotic arm 20, then through the rubber hose 30 into the spray arm connecting groove 26. Through the spray arm 27, water is sprayed out from the central spray nozzles 29 on both sides of the spray arm 27 to form a water curtain. When the valve c32 is opened, water can also flow into the spray claw 28 and spray out from the spray claw outlet 28-1 at the top for precise spraying. The two sides of the housing 36 are equipped with servo motors 44. When the servo motors 44 are started, they will drive the hollow shaft rotating joint 17 and its components to rotate 360 ​​degrees.

[0035] Furthermore, a housing 36 is mounted on the supporting base plate 4. This housing 36 forms the main load-bearing frame of the entire device and the central controller 56. The front end of the housing 36 is equipped with an air purifier dust baffle 35, an air purifier 45, and an air purifier support plate 46. The air purifier dust baffle 46 is fixedly connected to the lower front end of the housing 36. The air purifier 45 is fixedly installed on the air purifier support plate 46 and is used to filter and purify the intake air. The air purifier dust baffle 35 blocks large particles in the air, preventing impurities from directly entering the air purifier 45. Two dustproof doors 33 are located at the upper end of the air purifier support plate 46, each equipped with a dustproof door switch 34. The dustproof doors 33 seal the housing 36, providing dustproof protection for the core equipment inside, such as the electrical control system, and preventing external dust from entering. The air purifier 45 is kept in a normal working environment. The rear end of the housing 36 is equipped with a rear water outlet 47, a rear water inlet 48, and an electromagnetic acoustic energy harvester 49 based on a Helmholtz resonator. The electromagnetic acoustic energy harvester 49 based on a Helmholtz resonator is an energy recovery device that collects the noise generated by construction, generates mechanical vibration through resonance effect, and converts it into electrical energy through an electromagnetic conversion structure. The electrical energy is transmitted to the energy storage unit in the central controller 56 via the energy and auxiliary control module 60 and stored therein, providing auxiliary power for the low-power circuits in the central controller 56, the environmental perception and decision module 57, and the motion control module 58. When the rear water outlet 47 is opened, the remaining water in the device is discharged. When the rear water inlet 48 is opened, external water can enter the water tank 11 through the rear water inlet 48 to replenish the water. Example 2

[0036] Based on Embodiment 1, the air purifier 45 includes a suction horn 45-1, a vibration dust-shaking switch 45-2, a suction switch 45-3, a dust-filtering vibration mesh 45-4, an annular air storage chamber 45-5, a spiral channel pipe 45-6, and a ventilation pipe 45-7. The ventilation pipe 45-7 is fixedly connected to the air purification chamber 52. The air purification chamber 52 is provided with an air channel pipe 52-1. A small partition 51 is welded to the air channel pipe 52-1, and a large partition 50 is provided around the small partition 51. The upper end of the large partition 50 is equipped with a sealing plate 55, and the lower end of the large partition 50 is equipped with an air purifier support plate 46. When the vacuum switch 45-3 is turned on, the dust-laden airflow converges after passing through the reduced surface of the vacuum horn 45-1 and impacts the dust filter vibration mesh 45-4. Large particles of 100 microns or larger are intercepted on the dust filter vibration mesh 45-4. The vibration and dust shaking switch 45-2 is periodically activated, driving the dust filter vibration mesh 45-4 to generate high-frequency micro-amplitude vibrations, thereby removing the trapped particles. Particulate matter is shaken off to prevent blockage and maintain the unobstructed airflow channel of the air purifier 45. The airflow entering the air purifier 45 is tangentially directed into the annular air chamber 45-5, where a forced vortex is formed under the guidance of the spiral channel tube 45-6. Under the action of force, medium-sized particles of 10-100 micrometers are thrown against the outer wall of the chamber and accumulate, achieving preliminary gas-solid separation. The annular air chamber 45-5 and the ventilation tube 45-7 are detachably connected for easy periodic cleaning. The preliminarily purified gas then passes through... The vent pipe 45-7 enters the air purification chamber 52 for further purification. The further purified air will enter the closed cavity formed by the large partition 50, small partition 51, sealing plate 55, air purifier support plate 46 and dust door 33 through the air channel pipe 52-1. When the dust door switch 34 is opened, the purified air will be discharged to the external environment. At the same time, every 5 minutes, the vibration dust-shaking switch 45-2 will be opened to shake off large particles on the dust filter vibration screen 45-4 to prevent blockage.

[0037] Furthermore, the upper end of the housing 36 is equipped with a water collection tank 38 and a vision recognition module 37. In a non-rainy environment, the vision recognition module 37 is used to identify the location, concentration, and diffusion status of dust sources in the construction area, and feeds the detection data back to the environmental perception and decision-making module 57, which in turn transmits it to the central controller 56. The central controller 56 then immediately sends a path planning command to the motion control module 58, which in turn drives the stepper motor 3 to output rotational torque. The stepper motor 3 directly drives the drive wheel 5 to rotate through a key connection with the drive wheel 5. The teeth of the drive wheel 5 precisely mesh with the meshing holes of the track surface 2. With the help of friction and meshing force, the entire track 53 is driven to move. The idler wheel 1... In coordination with the track 53, pre-tension is applied to the track 53 to guide its smooth winding, bringing the entire device to the designated position. During this process, the vacuum switch 45-3 remains open, the air purifier 45 purifies the air, the servo motor 44 receives the position command and drives its output shaft to rotate to a designated angle, causing the hollow shaft rotary joint 17 and all its components to reach the predetermined position. The cylindrical servo motor 17-2 receives the position command and outputs precise rotational torque, driving the robotic arm 20 and all its components to rotate 360 ​​degrees around the vertical axis in the horizontal plane. The small cylindrical servo motor 22 receives the position command and outputs precise rotational torque. The torque drives the angle rotation shaft 25 to rotate, thereby causing the spray arm connecting groove 26 and the spray arm 27, which are fixed to the shaft connecting part 20-1, to pitch and swing in a plane perpendicular to the horizontal plane. When the spray arm 27 reaches the designated position, the operator operates the water circuit and dust suppression control module 59 to open the water pump 12 and valve b13. The water pump 12 pressurizes the water in the water tank 11 and pumps it out. The pressurized water flows through the connecting pipe 16 to the valve b13 and flows into the spray arm water supply pipe 14 and the upper water pipe 15. The water flowing into the spray arm water supply pipe 14 is injected through the robotic arm water inlet 17-1 and passes through the central cavity of the cylindrical servo motor 17-2 into the robotic arm 27. The water flows through the cavity of the spray arm 27, then through the rubber hose 30 into the spray arm connecting groove 26. It is sprayed out in coordination with the central spray nozzles 29 evenly distributed on both sides of the spray arm 27 to form a uniform and wide fan-shaped water curtain, performing large-scale dust suppression coverage. The water also flows into the spray claw 28. When it is necessary to carry out fixed-point dust suppression, the operator can open the valve c32 separately through the water circuit and the dust suppression control module 59. The water is sprayed out from the spray claw outlet 28-1 at the top of the spray claw 28 to form a concentrated water flow. The design of these two water circuits not only realizes the large-scale settling of dust in the area, but also strengthens dust suppression for key dust sources or weak areas covered by the water curtain, improving the overall efficiency of dust reduction.

[0038] Furthermore, a spray flower core 54 is provided at the upper end of the telescopic bracket 42, and six spray petals 41 are equidistantly arranged around the spray flower core 54. Five spray petal nozzles 41-1 are equidistantly arranged on the spray petals 41. A water flow switch 43 is provided at the upper end of the telescopic bracket 42. A water filter screen 39 and a water collection horn 40 are respectively provided on the spray flower core 54. After pressurized water flows into the upper water pipe 15, it enters the water collection tank 38, and then flows through the water flow switch 43. After passing through the spray flower core 54, it is distributed to the six spray petals 41. According to the dust suppression requirements, the operator can manually raise the telescopic bracket 42 to a suitable height and open the water flow switch 43 through the water circuit and dust suppression control module 59. The water flow is evenly sprayed from the spray nozzles 41-1 on each spray petal 41 to form a large-coverage umbrella-shaped water curtain, realizing a larger area of ​​spraying in the work area.

[0039] Furthermore, during rainy days when there is no spraying operation, the operator opens valve c32 through the water circuit and dust suppression control module 59. Rainwater is collected by the water collection horn 40 and filtered on the water filter screen 39. It then flows along the spray flower core 54 into the water collection tank 38 for storage. When dust suppression operation is required, the water pump 12 can preferentially draw water from the water collection tank 38 to supply the spray arm 27, spray claw 28 or top spray petal 41, thereby supplementing part of the water source.

It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
