Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to an asphalt paving device for road construction. Background Art

[0002] When paving asphalt on a road, it is necessary to use a pressure roller to flatten it while paving, so that the paved asphalt road surface can be paved flat. After searching, the Chinese patent authorization number is CN217896141U, which discloses an asphalt paving device for road construction, the cleaning mechanism includes a mounting seat, both sides of the bottom of the mounting seat are connected with a first mounting plate, the bottom of the connecting rod on both sides is connected with a scraper, the inside of the mounting frame is connected with a pressure roller, both sides of the second mounting plate on both sides are provided with threaded holes, and the inside of the threaded holes on both sides are screwed with second threaded pipes. The asphalt paving device for road construction rotates the second threaded pipes on both sides to disengage them from the inside of the threaded holes on both sides. At this time, the scraper moves downward by the rebound force of the spring, and the scraper contacts the pressure roller. When the pressure roller rotates, the asphalt adhered to the pressure roller is scraped off by the scraper, so that the asphalt adhered to the pressure roller is convenient to remove, saving a lot of time and physical strength, and the cleaning efficiency is very high, and no additional tools are needed for cleaning. However, the device uses a scraper to clean the asphalt stuck to the roller during paving. The mounting seat moves to the right and the scraper is set above the roller. No matter from which direction the roller is cleaned, the asphalt stuck to the roller either falls on the left side of the roller or is pushed between the scraper and the roller, causing the attachments cleaned by the roller to appear on the road surface after the subsequent road surface work is completed, making the road surface uneven. At the same time, asphalt falls through the mixing barrel and forms an accumulation. Even if the road surface is rolled by the roller, the accumulated asphalt cannot be completely leveled, which reduces the use efficiency of the device. Utility Model Content
