The ventilation duct 11 passes through the workbench 1 and extends to the outside of the workbench 1. An air collection box 12 is fixedly connected to the bottom of the ventilation duct 11. An elongated exhaust port 13 is provided at the bottom of the air collection box 12. A diffuser hood 14 is fixedly connected to the bottom of the air collection box 12. A through hole 15 is provided on one side of the diffuser hood 14. A round rod 16 is movably connected inside the through hole 15. The round rod 16 passes through the through hole 15 and extends to the outside of the through hole 15. An adjusting plate 17 is fixedly connected to the outer surface of the round rod 16. An adjusting motor 18 is fixedly connected to one side of the diffuser hood 14. One end of the adjusting motor 18 is fixedly connected to one end of the round rod 16. A limiting block 19 is fixedly connected to the other end of the round rod 16.

[0029] The workbench 1 supports the entire structure; the bracket 2 is used to fix the hot air box 3; the air pump 4 draws in air through the suction pipe 6 and delivers the gas into the hot air box 3 through the air delivery pipe 5; while the air delivery pipe 5 is delivering the gas, its airflow impacts the rotating blade 9, which drives the connected rotating shaft 8 to rotate, thereby agitating the air inside the hot air box 3; the circular sleeve 7 ensures the stable rotation of the rotating shaft 8; the heating block 10 is responsible for heating the air inside the hot air box 3; the ventilation pipe 11 transmits the hot air inside the hot air box 3 to the air collection box 12; the elongated exhaust port 13 at the bottom of the air collection box 12 guides the hot air to the diffuser hood 14; the diffuser hood 14 diffuses the hot air over a large area onto the road surface; the adjusting motor 18 drives the circular rod 16 to rotate in the perforation 15, which drives the adjusting plate 17 to change the angle, thereby controlling the direction and range of the hot air.

[0030] A rotary motor 20 is fixedly connected to the top of the workbench 1, and an output shaft 21 is fixedly connected to the bottom of the rotary motor 20. The outside of the output shaft 21 is movably connected to the inside of the workbench 1. The output shaft 21 passes through the workbench 1 and extends to the outside of the workbench 1. A circular tube sleeve 22 is fixedly connected to the bottom of the output shaft 21. A spring 23 is provided inside the circular tube sleeve 22. A vertical semi-circular groove 24 is opened on the inner wall of the circular tube sleeve 22. A semi-circular block 25 is slidably connected inside the vertical semi-circular groove 24. A circular block 26 is fixedly connected to the inner side of the semi-circular block 25. An extension rod 27 is fixedly connected to the bottom of the circular block 26. The extension rod 27 passes through the circular tube sleeve 22 and extends to the outside of the circular tube sleeve 22. A turntable 28 is fixedly connected to the bottom of the extension rod 27. Brush bristles 29 are provided at the bottom of the turntable 28.

[0031] The rotary motor 20 at the top of the workbench 1 drives the cylindrical sleeve 22 to rotate via the output shaft 21, thereby driving the brush bristles 29 below to perform road cleaning operations. The spring 23 inside the cylindrical sleeve 22 is a key component. It can quickly compress and absorb the impact force when the brush bristles 29 encounter road bumps or obstacles. If it encounters a large stone, it can help the brush bristles 29 avoid it, reducing wear. Afterward, it quickly returns to its original position. Its elasticity also allows the brush bristles 29 to automatically adjust their position and pressure according to the road surface undulations, ensuring cleaning effect while evenly distributing friction force, preventing excessive wear in some areas, and buffering vibrations caused by road bumps. This reduces damage to the rotary motor 20, output shaft 21, and brush bristle 29 components, extending the equipment's lifespan. The vertical semi-circular groove 24 on the inner wall of the round tube sleeve 22 is closely fitted with the semi-circular block 25. During this process, the semi-circular block 25 slides in the vertical semi-circular groove 24, which not only ensures the stability of the direction of the round block 26 and the connected extension rod 27, turntable 28 and brush bristles 29 when they move up and down, preventing deviation and shaking, and ensuring smooth and orderly cleaning; but also, when the brush bristles 29 are impacted, they can share part of the force of the spring 23 through their own sliding and friction, enhance the impact resistance of the device, further help to extend the service life of the equipment and improve the overall performance.

[0032] A maintenance box 30 is fixedly connected to the top of the workbench 1.

[0033] Maintenance tools and spare parts are stored in the maintenance box 30 on top of the workbench 1. In case of equipment failure, these tools and spare parts can be quickly accessed by staff to repair critical components in a timely manner, reducing downtime, improving maintenance efficiency, and ensuring the continuous and stable operation of the cleaning work.

[0034] A mounting plate 31 is fixedly connected to one side of the workbench 1.

[0035] The mounting plate 31 is connected to one side of the workbench 1 to provide a mounting base for the equipment, making it easy to connect to other objects such as vehicles and brackets, and meeting the usage needs of different scenarios.

[0036] An inclined column 32 is fixedly connected to one side of the mounting plate 31, and the other end of the inclined column 32 is fixedly connected to the bottom of the workbench 1.

[0037] The inclined column 32, connected to one side of the mounting plate 31, is fixed to the bottom of the workbench 1 at the other end, which enhances the structural stability. The inclined column 32 connects the two in an inclined manner, and through the stability principle of the triangular structure, it disperses the pressure and vibration borne by the device during operation, prevents the mounting plate 31 from loosening or falling off the workbench 1, and ensures the stable operation of the entire device.

[0038] The mounting plate 31 has a mounting hole 33 on one side.

[0039] The mounting holes 33 on one side of the mounting plate 31 allow users to securely fix the mounting plate 31 to vehicles or other equipment using bolts, nuts, or other connectors, enabling convenient installation and positioning of the entire device and ensuring stable operation.

[0040] A fixing plate 34 is fixedly connected to the bottom of the workbench 1, and one side of the fixing plate 34 is fixedly connected to one side of the air collection box 12.

[0041] By connecting the bottom of the workbench 1 to one side of the air collection box 12 with the fixing plate 34, the position of the air collection box 12 can be stabilized, preventing it from shaking or shifting during operation, ensuring stable hot air transmission, and guaranteeing the overall structural stability and working efficiency of the cleaning device.

[0042] The working principle of the asphalt distributor road cleaning device provided by this utility model is as follows: First, when the air pump 4 is started, it draws air from the outside through the suction pipe 6, and then delivers the drawn air to the hot air box 3 through the air delivery pipe 5. During this process, the air outlet of the air delivery pipe 5 faces the rotating blade 9, and the strong airflow impacts the rotating blade 9. Since the rotating blade 9 is fixedly connected to the rotating shaft 8, the impact force of the airflow will drive the rotating shaft 8 to start rotating, thereby causing the rotating blade 9 to rotate accordingly. At the same time, the heating block 10 installed inside the hot air box 3 heats the air inside the box. The rotation of the rotating blade 9 helps the hot air to be distributed more evenly in the hot air box 3, so that the hot air is fully mixed in the box, ensuring the temperature uniformity and stability of the hot air. Then, the heated and evenly distributed hot air is transferred to the air collection box 12 through the ventilation pipe 11. The elongated exhaust port 13 at the bottom of the air collection box 12 will exhaust the hot air, which then enters the air diffuser hood 14. The hot air is diffused over a large area, ensuring it evenly and extensively covers the road surface to be treated, thus drying the surface. In winter, the continuous hot air further melts the ice layer, reducing the adhesion of gravel and debris to the road surface, creating favorable conditions for subsequent cleaning. Finally, when it is necessary to adjust the direction and range of the hot air according to different road conditions or operational requirements, the regulating motor 18 starts working, driving the round rod 16 to rotate within the perforation 15 on one side of the diffuser shroud 14. Because the regulating plate 17 is fixed to the outer surface of the round rod 16, the rotation of the round rod 16 causes the regulating plate 17 to change its angle, thereby achieving flexible control of the hot air and allowing it to be precisely blown onto different road surface areas according to specific needs.

[0043] Compared with related technologies, the asphalt distributor road cleaning device provided by this utility model has the following advantages:

[0044] Beneficial effects:

[0045] This utility model provides a road surface cleaning device for an asphalt distributor. The device begins operation with a hot air box 3 supported by a bracket 2 on a workbench 1. An air pump 4 delivers air through an air pipe 5, which, in conjunction with a heating block 10, generates hot air to combat the low-temperature dampness of frost. Inside the hot air box 3, a rotating shaft 8 and a rotating blade 9 ensure even distribution of the hot air. The hot air then travels through a ventilation pipe 11 to a collection box 12, and is finally blown onto the road surface through an elongated exhaust port 13 and a diffuser hood 14, accelerating the melting of frost. Depending on the frost condition of the road surface, an adjusting motor 18 drives a round rod 16 to rotate, which in turn drives an adjusting plate 17 to regulate the direction and range of the hot air, ensuring stable operation of the device, improving the efficiency and flexibility of the drying process after cleaning, and ensuring the overall quality of the cleaning work.
