Abstract
Description
Technical Field
[0001] This utility model relates to the field of road roller technology, and in particular to an anti-sticking device for road rollers. Background Technology
[0002] As a core piece of equipment in road construction, airport runway construction, and large-scale site leveling, the core working component of a road roller is the roller itself, which compacts road materials through high-frequency vibration or static rolling pressure. During long-term use, the roller surface is prone to the adhesion of sticky materials such as asphalt, soil, and cement residue due to high temperature, high humidity, and the adhesive properties of the materials, leading to the following technical problems:
[0003] 1. Decreased compaction quality: Adhesive materials form an uneven coating on the roller surface, reducing the effective contact area between the roller and the compacted surface, resulting in unbalanced pressure distribution, uneven compaction density, and reduced surface smoothness, failing to achieve the expected flattening effect; 2. Adhesive materials increase the frictional resistance between the roller and the road surface, requiring additional power to overcome the adhesive force during compaction; 3. Existing technologies mainly rely on manual periodic cleaning or simple scraper mechanisms to remove adhesive materials from the roller surface, which is labor-intensive and inefficient. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-sticking device for road rollers to solve the above problems.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an anti-sticking device for a road roller, comprising a road roller bracket for assembling a roller, a drive vehicle connected to the road roller bracket, the road roller bracket being provided with an anti-sticking device and an anti-sticking drive device, the anti-sticking device including a removal screw, the removal screw being rotatably mounted on the road roller bracket, the removal screw being drively connected to the anti-sticking drive device, the removal screw being located near the lower side of the roller, the surface of the removal screw being provided with a threaded surface structure, the threaded surface structure being clearance-fitted with the roller surface of the roller.
[0006] In a further technical solution, the anti-sticking drive device includes a power drive device or a drive device without a power source.
[0007] In a further technical solution, the anti-sticking drive device includes a first driven wheel, a second driven wheel, and a third driven wheel that are sequentially meshed. The first driven wheel, the second driven wheel, and the third driven wheel are located on the same side of the roller support. A roller shaft is provided at the center of the roller. The first driven wheel is installed on the roller shaft of the roller. The second driven wheel is rotatably installed on the roller support. The third driven wheel is installed on the removal screw.
[0008] In a further technical solution, the transmission ratio between the first driven wheel, the second driven wheel, and the third driven wheel is 1:1:1.5-2.5.
[0009] In a further technical solution, the threaded surface structure includes multiple teeth, the outline of which is triangular, and the top of each tooth is rounded.
[0010] In a further technical solution, the height h of the tooth body is 8cm-20cm; the pitch d between two adjacent teeth body is 13cm-25cm.
[0011] In a further technical solution, the screw is removed, which includes a shaft and a threaded assembly. The threaded assembly includes a connecting rod sleeve and a threaded surface structure. The threaded surface structure is formed on the surface of the connecting rod sleeve. Different screw assemblies have different specifications of threaded surface structures formed on their surfaces.

[0012] In a further technical solution, pin fastening structures are provided on both sides of the shaft, and the threaded assembly is fastened to the shaft through the pin fastening structures.
[0013] The advantages of this invention compared to the prior art after adopting the above structure are:

[0016] 3. The screw removal mechanism adopts a replaceable design of shaft and threaded assembly. The thread surface specification can be quickly adjusted through the pin fastening structure, which can be adapted to rollers of different diameters and materials and materials with different adhesion strengths, making it highly versatile.
