Technical Field

[0001] The utility model relates to the technical field of engineering machinery equipment, in particular to an in-situ hot recycling mixer for asphalt pavement with a warm mix additive tank. Background Technique

[0002] In-situ hot recycling construction of asphalt pavement generally requires three types of equipment, namely a heating machine, a heating milling machine, and a recycling mixer, to work together. The heating machine heats the old asphalt pavement to a certain temperature to soften it, the heating milling machine mills and collects the softened asphalt pavement, and then the recycling mixer collects the milled material and adds an appropriate amount of newly mixed asphalt mixture, asphalt, recycling agent, and other additives (such as warm mix additive) to stir in a mixing pot. After the asphalt mixture meets the technical requirements for pavement construction, it is put into the hopper of a paver, and is paved by the paver, compacted and leveled by a roller.

[0003] The utility model with the authorization announcement number of "CN 205839534 U" has a simple structure, including a mixing pot. An inlet channel is arranged on the mixing pot, and it also includes a warm mix additive tank communicated with the inlet channel. The warm mix additive tank includes a tank body. An inlet and a hot air inlet are arranged at the top of the tank body. A scraping ring slidably connected with the tank body is arranged in the tank body, and the scraping ring is connected with the top of the tank body through a spring. The recycling mixer with this structure has the advantages of convenient addition of warm mix additive and no waste of warm mix additive.

[0004] However, the above solution cannot completely scrape off the warm mix additive adhering to the inner wall of the tank body, and there is still a certain residue. At the same time, the warm mix additive fed into the mixing pot is not evenly mixed with the asphalt concrete, resulting in the processed asphalt concrete not meeting the actual use requirements. Therefore, the utility model proposes a new solution. Content of the Utility Model

[0005] The purpose of the utility model is to provide an in-situ hot recycling mixer for asphalt pavement with a warm mix additive tank to solve the problems raised in the above background technique.
