Description

Technical Field

[0001] The utility model relates to the technical field of pavers, in particular to a hopper of an asphalt paver. Background Art

[0002] The asphalt paver was developed by Charles Burris Co., who originally manufactured material handling systems. In 1929, they were approached by the Chicago Test Laboratory to use their material loaders to build asphalt roads. This did not lead to a collaboration, but Babbergrin did develop a machine based on the concrete pavers of the time that mixed and placed concrete in a single process. It turned out that this setup did not work as well as expected, and the processes were separated, and the modern paver is in use. In 1933, the independent floating screed was invented, which when used in conjunction with a tamping bar provided uniform material density and thickness. Chuck Burris applied for a patent for a "Machine and process for paving roads" on April 10, 1936, and was granted U.S. Patent 2,138,828 on December 6, 1938.

[0003] In the past asphalt pavers, the asphalt remaining after the construction was completed could not be cleaned up properly, so it remained on the surface of the hopper. Over time, the asphalt that was not cleaned up would remain on the surface, affecting the construction effect. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model provides a push plate, and the push plate is provided with an arc scraper and an arc scraper 2 on the front side, which can scrape off the asphalt on the left and right ends and the bottom without leaving any dead angles. The push plate is installed on the groove through the bottom slider below, which can be better clamped. At the same time, the fixing blocks on the left and right ends of the push plate are also installed in the push plate groove. There are two protrusions at the upper and lower ends of the fixing block, respectively, for fixing the push plate.

There are four fixing plates above the base, which are fixed to the vertical plate and the base through threaded connection with the cross nut, making it more stable.

[0013] The utility model arranges a vertical plate, and a heating plate is arranged on the inner wall of the vertical plate. The vertical plate is arranged on both sides, so that the heating is evenly heated. The temperature can be adjusted by using a control button. The temperature display can show the temperature of the current heating plate. When working, the push plate is pushed along the bottom plate of the hopper to move it, and the arc scraper on the push plate and the arc scraper are used to scrape away the remaining asphalt residue. When the scraping is impossible or difficult to remove, the heating plate is used to heat the vertical plate. Since there is a short distance from the vertical plate, the advantage of such an arrangement is that the heating plate can be better protected, and the heating plate can also consume less heat. The vertical plate is heated to melt the asphalt, so that the residue is better pushed. The asphalt residue that is difficult to clean can be heated, and the cleaning effect is obvious, and it is easy and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS
