Description

Technical Field

[0001] The present application relates to the technical field of road leveling, and more specifically, to a municipal roadbed leveling device. Background Art

[0002] Municipal road construction is an important part of urban infrastructure construction. In municipal road construction, compaction is a very important process, which can improve the stability and flatness of the road, and improve the service life and safety performance of the road. Traditional rollers are mainly heavy rollers. Due to their large size and complex operation, they are difficult to be used in small construction sites such as urban roads. Therefore, small rollers have gradually been developed, which have compact structures and simple operations. They are suitable for small construction sites, especially urban roads, sidewalks, bicycle lanes, etc. During the use of small rollers, due to the debris and sticky substances that may exist on the ground, the surface of the steel wheel is easily attached to these substances, resulting in poor compaction effect. In order to solve this problem, small rollers are usually equipped with scrapers on the steel wheel to scrape off the adhesion on the surface of the steel wheel. However, due to the certain angle between the scraper and the steel wheel, the scraping effect of the scraper is not only limited, but also it is easy to accumulate a large amount of adhesion between the scraper and the steel wheel, affecting the scraping effect of the scraper.

[0003] The document with prior art publication number CN 220057543 U provides a leveling device for municipal road engineering. The device cooperates with each other among a fixing component, a connecting plate, a disc, a stud, a connecting disc, a spring, a triangular scraper, a guide component, a rotating block and a limiting mechanism. The device can realize cleaning of adhesions on the surface of a steel wheel while the roller is moving forward, and the adhesions will slide to both sides of the steel wheel along the inclined surface of the triangular scraper. Adhesions will not accumulate between the triangular scraper and the steel wheel, thereby improving the scraping efficiency and scraping effect of adhesions on the surface of the steel wheel.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: during the advancement of the device, a large amount of adhesions will be accumulated in the upper area of ​​the triangular scraper. If it cannot be cleaned in time, the adhesions will be adhered to the steel wheel for the second time.

[0005] In view of this, we propose a municipal roadbed leveling device. Utility Model Content

A spiral blade 3 which is rotatably connected to the steel wheel 2 is rotatably connected inside the cylinder 4. The cylinder 4 is parallel to the steel wheel 2. A strip hole 402 which fits the steel wheel 2 is formed in the cylinder 4. A debris discharge port 401 is formed at one end of the cylinder 4.

[0028] Reference Figure 1-Figure 3 When the lower edge of the strip hole 402 of the cylinder 4 is in contact with the steel wheel 2, during the advancement of the machine body 1, the adhesion is scraped off by the lower edge of the strip hole 402 of the cylinder 4, and the spiral blade 3 is rotated through the transmission connection between the steel wheel 2 and the spiral blade 3. Under the rotation of the spiral blade 3, the adhesion in the cylinder 4 is transported to the impurity discharge port 401 to clean the adhesion in the cylinder 4, and under the elastic connection between the cylinder 4 and the machine body 1, the adhesion between the cylinder 4 and the steel wheel 2 can be guaranteed.

[0029] The steel wheel 2 and the spiral blade 3 are both coaxially fixedly mounted with a synchronous pulley 201 , and a synchronous belt 202 is transmission-connected between the two synchronous pulleys 201 .

[0030] Reference Figure 1 Through the transmission of the synchronous pulley 201 and the synchronous belt 202, when the steel wheel 2 moves forward, the spiral blade 3 follows the rotation.

[0031] The body 1 is symmetrically fixed with a fixing frame 5 , and both ends of the cylinder 4 are fixedly installed with a connecting frame 6 hinged to the fixing frame 5 , and a tension spring 7 is fixedly installed between the connecting frame 6 and the fixing frame 5 .

[0032] Reference Figure 2 Under the elastic contraction of the tension spring 7, the connecting frame 6 and the cylinder 4 are tightly pressed toward the steel wheel 2 to ensure the fit between the cylinder 4 and the steel wheel 2.

[0033] The spiral blade 3 is in contact with the surface of the steel wheel 2 .

[0034] By the fit between the spiral blade 3 and the steel wheel 2 , when the spiral blade 3 fits the surface of the steel wheel 2 and rotates, the rotating spiral blade 3 can scrape off the adhered matter on the surface of the steel wheel 2 .
