[0014] A use method of a high-efficiency collecting device for highway road surface pollutants, characterized in that the method comprises the following steps: First step: on-site workers transport the device to a highway section to be cleaned. By starting the self-walking assembly, the walking wheels start to rotate. The power gear transmits power through meshing with the synchronous gear to drive the walking wheels to drive the entire device to move at a constant speed along the road surface. At the same time, the DC servo motor and the synchronous motor of the roller brush assembly are started to make the straight brush roller and the pair of inclined sweeping brushes rotate synchronously, preparing for the cleaning operation. Second step: during the movement of the device, the roller brush assembly works close to the road surface. The inclined sweeping brushes are arranged obliquely to sweep the garbage on the road shoulder and the edge area inward; the straight brush roller is responsible for pushing the garbage in the central area of the road surface backward to gather various pollutants to the area in front of the adsorption cover behind the cleaning bin. Third step: start the power suction pump to establish stable negative pressure in the collecting cylinder through the power connection pipe. The garbage suction pipe connects the adsorption cover and the collecting cylinder, and under the action of negative pressure, the garbage collected by the roller brush assembly is sucked into the adsorption cover and transported to the garbage blocking cavity in the collecting cylinder through the garbage suction pipe and falls on the filter core structure. Fourth step: when the garbage in the collecting cylinder reaches the upper limit of the capacity or needs to be cleaned, first, stop the device and close the power suction pump. Open the inspection cover and enter the equipment mounting area. Loosen the locking screws on the two limiting frames to make the limiting frames slide along the adjusting grooves. After the lateral limiting of the collecting cylinder is released, the power supply of the main magnet is disconnected. Lift the collecting cylinder upward, the adsorption force between the magnetic adsorption plate and the main magnet, and the rubber ring is separated from the side wall of the clamping groove to take out the collecting cylinder as a whole. Then open the collecting cylinder to dump the garbage or disassemble the fixing bolts to take out the filter core structure for cleaning or replacement. Fourth step: after cleaning or replacing the filter core, align the bottom of the collecting cylinder with the clamping groove on the fixing seat and place it downward. Make the rubber ring tightly fit with the side wall of the clamping groove, and the magnetic adsorption plate and the main magnet are automatically adsorbed and fixed. Then slide the two limiting frames to make the vertical rods of the limiting frames tightly fit with the side wall of the collecting cylinder, and tighten the locking screws to complete the lateral locking, and restart the device to continue the operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention allows the roller brush assembly to effectively gather garbage from different areas of the road surface by cooperating with the oblique sweeping brush and the straight brush roller; the negative pressure suction mechanism establishes negative pressure for the collection cylinder through a power suction pump, and quickly sucks the gathered garbage into the collection system through the adsorption hood and garbage suction pipe. This structure avoids the dust and garbage residue problems that are easily generated by traditional single sweeping methods, and significantly improves the comprehensiveness and cleanliness of garbage collection.

[0016] (2) The present invention uses a main magnet installed in the slot of the fixed seat and a magnetic suction plate installed at the bottom of the collection tube to achieve rapid alignment and adsorption fixation by using magnetic force; at the same time, the interference fit between the rubber retaining ring and the side wall of the slot further enhances the installation stability. This structure makes the collection tube less prone to loosening during operation and easy to separate during maintenance, which greatly improves loading and unloading efficiency and reduces the intensity of manual operation.

[0017] (3) The solution of the present invention can slide and lock along the surface of the fixed seat through the cooperation of the limiting frame, the adjusting groove and the locking screw, which can adapt to the collection tubes of different diameters. The L-shaped design can provide lateral support and is easy to adjust and fix, effectively preventing the collection tube from shifting during vehicle movement or vibration, thus enhancing the reliability and adaptability of the system.

[0018] (4) The present invention, by using a mounting bracket, air filter and rubber ring to install the filter element structure in the waste barrier chamber of the collection cylinder, can effectively intercept the sucked fine dust, prevent it from entering the power suction pump, and extend the service life of the equipment. At the same time, the filter element is connected to the collection cylinder by fixing bolts, which is convenient for individual disassembly, cleaning or replacement, and maintenance is convenient and does not affect other components.

[0019] (5) In the present invention, the collection chamber is divided into an item placement area and an equipment installation area by a partition. The former is equipped with hooks for storing maintenance tools and spare filter cartridges, while the latter is specifically used for installing core components such as collection cylinders and power suction pumps. This structure makes the device layout reasonable and the operating space clear, improving the systematic nature of equipment management and the orderliness of the work site.

[0027] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: When the solution of this invention is used in actual field: A method for using a high-efficiency collection device for highway pavement pollutants includes the following steps: Step 1: On-site personnel transport the device to the section of the highway to be cleaned. By activating the self-propelled assembly 12, the walking wheels 123 begin to rotate. The power gear 122 transmits power through meshing with the synchronous gear 121, driving the walking wheels 123 to propel the entire device forward at a constant speed along the road surface. Simultaneously, the DC servo motor 124 and synchronous motor 113 of the drive roller brush assembly 11 are started, causing the straight brush roller 114 and a pair of oblique sweeping brushes 111 to rotate synchronously, ready for cleaning operations. Step 2: During the movement of the device, the roller brush assembly 11 operates close to the road surface. The oblique sweeping brush 111 is arranged at an angle to sweep the garbage inward from the shoulder and edge areas; the straight brush roller 114 is responsible for pushing the garbage in the central area of ​​the road surface backward. The two work together to effectively gather various pollutants (including large particles and fine dust) to the area directly in front of the adsorption hood 43 behind the sweeping chamber 2; Step 3: Start the power suction pump 42 to establish a stable negative pressure inside the collection cylinder 41 through the power connection pipe 45. The garbage suction pipe 44 connects the adsorption hood 43 to the collection cylinder 41. Under the action of negative pressure, the garbage collected by the roller brush assembly 11 is sucked into the adsorption hood 43 and transported to the garbage barrier chamber 401 inside the collection cylinder 41 through the garbage suction pipe 44. The filter structure 6 set in the garbage barrier chamber 401 can effectively filter fine dust and prevent it from entering the power suction pump 42, while ensuring air circulation and maintaining the continuous and efficient operation of negative pressure adsorption. Step 4: When the waste in the collection cylinder 41 reaches its maximum capacity or needs to be cleaned, first turn off the power suction pump 42 and stop the device from operating. Open the inspection cover 21 and enter the equipment installation area 302. Loosen the locking screws 55 on the two limit brackets 54, allowing the limit brackets 54 to slide along the adjustment groove 501. After releasing the lateral limit on the collection cylinder 41, disconnect the power to the main magnet 51. Pull the collection cylinder 41 upwards; the magnetic suction plate 52 and the main magnet 51 will attract each other, and at the same time, the rubber retainer 53 will disengage from the side wall of the slot 304, allowing the collection cylinder 41 to be removed as a whole. The collection cylinder 41 can then be opened to empty the waste, or the fixing bolts 64 can be removed to remove the filter element structure 6 for cleaning or replacement. Step 4: After cleaning or replacing the filter element, align the bottom of the collection cylinder 41 with the slot 304 on the fixing base 303 and place it downwards. Ensure the rubber retaining ring 53 fits tightly against the side wall of the slot 304; the magnetic plate 52 will automatically attract the main magnet 51, securing the bottom. Next, slide the two limiting brackets 54 so that their vertical rods are flush against the side wall of the collection cylinder 41, tighten the locking screw 55 to complete the lateral locking, and restart the device to continue operation.

[0028] The above-disclosed embodiments are only a few specific examples of the present invention.
