Abstract
Description
Technical Field
[0001] This utility model relates to the field of road construction equipment technology, specifically a self-cleaning asphalt pavement compaction device. Background Technology
[0002] In asphalt pavement construction, the compaction process is crucial to pavement quality. Traditional compaction devices often suffer from asphalt, gravel, and other impurities adhering to the roller surface during operation, affecting compaction efficiency and leading to scratches, unevenness, and other defects. Furthermore, manually applying anti-sticking agent frequently to prevent "roller sticking" is inefficient and difficult to achieve even coverage, severely hindering construction progress. In addition, existing devices often have fixed cleaning mechanisms that cannot be adjusted according to working conditions, and replacing worn brushes is inconvenient, increasing maintenance costs. Therefore, there is an urgent need for a compaction device that can simultaneously perform automatic cleaning and anti-sticking spraying, and is adjustable, to improve the quality and efficiency of asphalt pavement construction and address the pain points of traditional equipment in practical applications.
[0003] Asphalt pavement compaction device disclosed in authorization announcement number CN216864729U includes a roller, a vehicle body, a bearing, and a bearing rod. The bearing rod is installed at the front end of the vehicle body, and the bearing is installed at the front end of the bearing rod. A roller shaft on the roller is rotatably connected to the bearing. The bearing is sealed in a housing containing lubricating oil. The bearing rod and the roller shaft pass through the housing. The portion of the roller shaft passing through the housing is coaxially fitted with a first pressure cap, a filler box, and a second pressure cap in sequence. The first pressure cap is fixed to the outer surface of the housing. Filler is provided between the filler box and the roller shaft. The filler is clamped in the sealed space between the first and second pressure caps. The end of the filler box near the first pressure cap has a first flange extending radially outward. The first pressure cap has a first axial protrusion extending towards the sealed space. The first flange of the filler box is connected to the first pressure cap through a first filler clamping assembly. This utility model can ensure smooth rotation of the roller and stable compaction of the pavement.
[0004] Although the above-mentioned solution improves the compaction stability of the roller through the connection design between the structures, the device lacks automatic cleaning and anti-sticking measures for the roller during use, which makes it difficult to ensure the compaction effect and efficiency of the roller. To address this, we propose a self-cleaning asphalt pavement compaction device, which solves the problems of automatic cleaning and anti-sticking of the roller, improves the compaction effect of the device, ensures the compaction smoothness of the asphalt pavement, and also improves the efficiency of road operation.

[0023] Example: A self-cleaning asphalt pavement compaction device, such as Figures 1-4 As shown, the device includes a compaction wheel 1, with connecting arms 3 movably connected to both ends of the compaction wheel 1 via pins 2. A limit groove 4 is formed on the side of the connecting arm 3, and a limit block 5 is slidably installed inside the limit groove 4. A scraper 6 is bolted to the side of the limit block 5 near the compaction wheel 1. An operating groove 14 is formed on the connecting arm 3 near the crossbar 7 of the limit groove 4. An adjusting screw 15 is threaded through and connected to the inside of the limit block 5. One end of the adjusting screw 15 is rotatably connected to the limit groove 4 via a bearing, and the other end... One end of the adjusting screw 15 passes through the limiting groove 4 and extends into the operating groove 14. A hexagonal rotating block 16 is fixedly installed at one end of the adjusting screw 15 near the operating groove 14. The adjusting screw 15 is rotatably connected to the limiting groove 4 and the operating groove 14 through bearings. Several hard bristles 25 are fixedly installed on the scraper 6 near the side of the rolling wheel 1. The ends of the hard bristles 25 are in contact with the surface of the rolling wheel 1. A connecting block 23 is fixedly installed at the midpoint of the side of the crossbar 7 away from the rolling wheel 1. A connecting hole 24 is opened inside the connecting block 23.
[0024] In this embodiment, the scraper 6 and hard bristles 25 provided on one side of the rolling wheel 1 can remove impurities adhering to the surface of the rolling wheel 1, thereby ensuring the cleanliness of the surface of the rolling wheel 1. When the hard bristles 25 wear down, rotating the hexagonal rotating end clockwise drives the adjusting screw 15 to rotate, thereby moving the limiting block 5 and the scraper 6 towards the rolling wheel 1, so that the hard bristles 25 come into contact with the surface of the rolling wheel 1. This adjustment method improves the utilization rate of the scraper 6 and the bristles, thereby reducing the operating cost of the device.
[0025] like Figures 1-2As shown, a crossbar 7 is fixedly connected to the end of the connecting arm 3 away from the compaction wheel 1. A support plate 8 is fixedly welded to the side of the crossbar 7 near the compaction wheel 1. A water storage tank 9 is fixedly installed on the top of the support plate 8. A water pump 10 is connected to the outlet of the water storage tank 9. A spray pipe 12 is connected to the output end of the water pump 10 through a water supply pipe 11. Multiple mist nozzles 13 are evenly arranged on the side of the spray pipe 12 near the compaction wheel 1. The water pump 10 is fixedly installed on the top surface of the support plate 8. A valve 17 is installed on the outside of the connection section between the water supply pipe 11 and the spray pipe 12. The water spray pipe 12 is located above the scraper 6. An L-shaped mounting plate 18 is fixedly installed on the top surface of the connecting arm 3 by bolts. Both ends of the water spray pipe 12 are fixedly installed on the side of the L-shaped mounting plate 18 near the roller 1. A slot 19 is opened on the top surface of the support plate 8. An installation hole is opened inside the slot 19. A card plate 20 matching and fitting into the slot 19 is fixedly installed at the bottom of the water storage tank 9. The card plate 20 is fixedly installed inside the slot 19 by bolts. A water inlet 21 is fixedly installed at the top of the water storage tank 9. A liquid level window 22 is fixedly installed on one side of the water storage tank 9.
[0026] In this embodiment, by connecting the water pump 10 to the vehicle control system and power supply, a special anti-sticking agent or water is injected into the water tank 9. The liquid level window 22 set on one side of the water tank 9 can help the staff observe the changes in the liquid level in the water tank in real time, so as to determine whether the water tank is full or when to add anti-sticking agent. Then, the valve 17 is opened and the water pump 10 is turned on, so that the special anti-sticking agent or water in the water tank 9 is pumped into the spray pipe 12 and sprayed out by the mist nozzle 13 set on one side of the spray pipe 12 onto the surface of the rolling wheel 1, thereby achieving the anti-sticking wheel effect of the rolling wheel 1.
[0027] In this embodiment, a self-cleaning asphalt pavement compaction device is first connected to the roller body via a connecting block 23 on one side of the crossbar 7 using a pin. The roller body drives the roller 1 to roll, achieving the compaction effect on the asphalt pavement. During the compaction process, the scraper 6 and hard bristles 25 on one side of the roller 1 can remove impurities adhering to the surface of the roller 1, thereby ensuring the cleanliness of the roller 1 surface and improving the compaction effect. When the hard bristles 25 wear down, the adjusting screw 15 is rotated clockwise by rotating the hexagonal rotating end, thereby moving the limiting block 5 and the scraper 6 towards the roller 1, so that the hard bristles 25 come into contact with the surface of the roller 1. This adjustment method improves the utilization rate of the scraper 6 and the bristles, thereby reducing the operating cost of the device and saving resources. Before or during compaction, the water pump 10 is connected to the vehicle control system and power supply. A special anti-sticking agent or water is injected into the water tank 9. The valve 17 is opened and the water pump 10 is turned on, so that the special anti-sticking agent or water in the water tank 9 is pumped into the water spray pipe 12 and sprayed onto the surface of the compaction wheel 1 by the mist nozzle 13 set on one side of the water spray pipe 12. This achieves the anti-sticking effect of the compaction wheel 1, thereby ensuring the quality and efficiency of the compaction operation.
