[0002] Asphalt concrete mixing tank refers to equipment used to mix asphalt concrete. In asphalt concrete construction, the mixing tank plays a vital role. Through the mixing tank, asphalt, aggregate, cement and other raw materials can be fully mixed to ensure the quality and uniformity of concrete. The mixing tank is usually composed of mixing blades, motors, transmission devices and other components. The raw materials are mixed by rotating the mixing blades.

[0003] At present, the asphalt concrete mixing cylinder of the prior art has the following disadvantages during use;

[0004] On the one hand, after the asphalt concrete material is mixed, the agitator needs to be removed from the mixing barrel by the lifting structure, and then the mixing barrel needs to be driven by an electric device to flip and pour out the material. It is impossible to realize the structure that the mixing barrel can be automatically linked to flip and pour out the material during the process of the agitator moving up and out of the mixing barrel, so the number of electric drive devices used increases, and the cost is high;

[0005] On the other hand, the mixing barrel needs to be cleaned after use. However, the mixing barrel in the prior art is welded and fixed, which is not convenient for disassembly, resulting in great difficulty in subsequent cleaning. For this reason, we have designed an asphalt concrete mixing cylinder to solve the above problems. Utility Model Content
