[0002] A road roller, also known as a soil compactor, is a piece of equipment used for road construction. Among engineering machinery, road rollers belong to the category of road equipment and are widely used in filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can compact sandy, semi-viscous and cohesive soils, roadbed stabilized soils, and asphalt concrete pavement layers. The road roller uses the gravity of the machine itself and is suitable for various compaction operations, causing the compacted layer to be permanently deformed and compacted. After the rollers are rolled on wet ground, a large amount of water will remain, which needs to be cleaned in time, so the equipment needs to be cleaned.

[0003] A water absorption and anti-pollution device for the roller is needed during the use of the roller. During the asphalt pavement paving and rolling process of the roller in the prior art, the rolling equipment, the double-steel wheel roller, needs to spray water to moisten the rolling wheels during the rolling process, and separate the rolling wheels from the asphalt through the water, thereby achieving a smooth asphalt surface. However, the rolling wheels will temporarily develop scale similar to that of a kettle when sprayed with water at high temperatures for a long time, which will cause yellowish spots on the asphalt pavement surface. The existing rollers are not convenient for handling water stains, which seriously affects the production quality of asphalt pavement paving and cannot meet production needs. Therefore, a water absorption and anti-pollution device for the roller is proposed to solve the above-mentioned problems. Utility Model Content

[0022] Embodiment 1:

[0023] See also Figures 1 to 4The roller water absorption and pollution prevention device in this embodiment comprises a roller 1 and a frame 2 arranged outside the roller 1. A water absorption mechanism 3 for absorbing water outside the roller 1 is arranged outside the frame 2. The water absorption mechanism 3 comprises a mounting plate 31 fixedly connected to the outside of the right side of the frame 2. An electric push rod 32 is hinged on one side of the bottom of the mounting plate 31. A connecting rod 33 is hinged on the other side of the bottom of the mounting plate 31. The end of the electric push rod 32 away from the mounting plate 31 is hinged with the connecting rod 33. A fixing plate 34 is fixedly connected at the hinge between the electric push rod 32 and the connecting rod 33. An installation box 35 is fixedly connected to the outside of the fixing plate 34. A reduction motor 36 is fixedly installed on the outside of the installation box 35. A rotating shaft 37 extending to the inside of the installation box 35 is fixedly connected to the output shaft of the reduction motor 36. Four sponge plates 38 are fixedly connected to the outside of the rotating shaft 37. The roller 1 is rotatably connected to the inside of the frame 2.

[0024] The controller is used to start the electric push rod 32 to extend and retract, driving the connecting rod 33 to tilt, so that the fixed plate 34 drives the installation box 35 to move closer to or away from the roller 1, and then the controller is used to start the reduction motor 36 to drive the rotating shaft 37 to rotate. The rotation of the rotating shaft 37 drives the sponge plate 38 to rotate, so that the sponge plate 38 absorbs the water stains on the outside of the roller 1, effectively improving the water absorption efficiency of the roller 1 and achieving the advantage of good water absorption effect.

[0025] The rotating shaft 37 is a solid cylinder, and a bearing adapted to the rotating shaft 37 is fixedly installed inside the mounting box 35. By providing the bearing, the stability of the rotating shaft 37 during rotation is improved.

[0026] Specifically, four sponge plates 38 are distributed in a ring shape outside the rotating shaft 37 , and a movable opening adapted to the sponge plates 38 is opened inside the installation box 35 .

[0027] It should be noted that the roller 1 is a conventional technology known to the public in the prior art, so its specific structure and working principle will not be described in detail in this article.

[0028] In this embodiment, the upper surface of the frame 2 is provided with a water spray mechanism 4 extending to the lower surface thereof, and the water spray mechanism 4 includes a water tank 41 fixedly connected to the top of the frame 2 and a mounting pipe 43 fixedly mounted on the inner top wall of the frame 2. A booster pump 42 is fixedly mounted on the left side of the water tank 41 and located at the top of the frame 2, and a plurality of nozzles 44 are fixedly connected to the bottom of the mounting pipe 43. The booster pump 42 is started by the controller to pump the water inside the water tank 41 to the inside of the mounting pipe 43 through the connecting pipe 45 and the delivery pipe 46, and then sprayed out through the nozzle 44, so as to spray water on the road roller 1, separate the rolling wheel from the asphalt through the water, and achieve the asphalt surface leveling effect.

[0029] The water tank 41 is a hollow cuboid, and a plurality of nozzles 44 are evenly spaced and distributed at the bottom of the mounting pipe 43 .

The hydraulic cylinder 51 is activated by the controller to extend and retract to drive the scraper 52 to move left and right, so that the scraper 52 abuts against the outer surface of the roller 1, thereby cleaning the impurities attached to the outside of the roller 1, improving the stability of the roller 1 when working, and achieving the advantage of strong practicality.

[0033] The length of the scraper 52 is adapted to the outer diameter of the roller 1 .

[0034] The adoption of the above technical solution makes it easy to clean the impurities attached to the outside of the roller 1, thereby improving the stability of the roller 1 during operation and achieving the advantage of strong practicality.

[0035] The working principle of the above embodiment is:

[0036] When in use, the controller starts the electric push rod 32 to extend and retract, driving the connecting rod 33 to tilt, so that the fixed plate 34 drives the installation box 35 to move closer to or away from the roller 1, and then the controller starts the reduction motor 36 to drive the rotating shaft 37 to rotate. The rotation of the rotating shaft 37 drives the sponge plate 38 to rotate, so that the sponge plate 38 absorbs the water stains on the outside of the roller 1, effectively improving the water absorption efficiency of the roller 1. The controller starts the booster pump 42 to draw water from the water tank 41 to the inside of the installation pipe 43 through the connecting pipe 45 and the conveying pipe 46, and then sprays it through the nozzle 44 to wet the roller 1 with water, and separate the rolling wheel from the asphalt by the water, so as to achieve the effect of leveling the asphalt surface. The controller starts the hydraulic cylinder 51 to extend and retract, driving the scraper 52 to move left and right, so that the scraper 52 abuts against the outer surface of the roller 1, thereby cleaning the impurities attached to the outside of the roller 1.
