AI Technical Summary
The installation structure of the existing road roller scraper lacks adjustment function, which leads to a larger gap between the scraper and the pressing wheel, which cannot be effectively adjusted, which is easy to damage and has poor cleaning effect.
An elastic adjustment device including a press wheel, a sludge scraper, a moving bracket, an adjustment bracket and a scraper is designed. By combining the adjustment spring and screw nut, automatic adjustment and convenient adjustment of the gap between the scraper and the presser wheel are achieved.
The adaptive adjustment of the gap between the scraper and the pressing wheel is achieved, avoiding foreign objects entering and contacting poorly, and improving the cleaning effect and service life of the scraper.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road rollers, in particular to the technical field of mud scrapers for road rollers. Background Art
[0002] In road paving projects, especially asphalt road paving projects, compacting the road surface with a road roller is an important process. Its working principle is that the road roller slowly drives on the newly paved road surface and uses the steel wheel of the road roller to compact the road surface. When the road roller is working, the asphalt or mud on the road surface easily adheres to the steel wheel, and the asphalt or mud adhering to the steel wheel needs to be scraped off by a scraper.
[0003] The existing scraper blade is generally fixedly mounted on the scraper frame. This mounting structure has no adjustment function and is easily damaged during use. Moreover, after long-term use, the gap between the scraper blade and the pressure wheel will gradually increase, and the gap cannot be adjusted. Summary of the Invention
[0004] The purpose of the utility model is to solve the problems in the prior art and to provide an elastic adjustment device for a scraper blade of a road roller, which can solve the above problems.
[0005] The adjusting screw is passed through the scraper frame, and the adjusting nut is rotatably mounted on the outer side of the scraper frame, and the adjusting nut is threadably mounted on the outer side of the scraper frame.
[0006] Preferably, the adjusting spring is sleeved on the outside of the adjusting slide rod.
[0007] Preferably, there are two adjusting screws, which are symmetrically arranged on both sides of the adjusting bracket.
[0008] Preferably, the scraper and the adjustment bracket are detachably mounted.
[0009] The beneficial effects of the utility model are as follows: when the scraper of the utility model is working, if a large foreign object enters the gap between the scraper and the pressure wheel, or when the scraper and the pressure wheel have poor contact, the scraper can overcome the pressure of the adjusting spring and move upward to avoid malfunction; by turning the adjusting nut, the gap between the scraper and the pressure wheel can be easily adjusted to ensure the cleaning effect of the scraper.
[0010] The features and advantages of the present invention will be described in detail through embodiments with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
