Problems solved by technology
In the existing technology, the rolling ring and the cylinder are directly welded and fixed together, but the thermal expansion and contraction of the drying cylinder easily cause weld seams to appear between the rolling ring and the cylinder, and the connection reliability is low
At the same time, the irregular impact force generated when the aggregate is turned and dropped will have an impact on the driving wheel and the transmission device, reducing the stability of the drive wheel and the transmission device

The invention relates to a supporting structure of a drying cylinder of asphalt mixture plant-mixed hot-recycling equipment. The supporting structure comprises a cylinder body and a rolling ring, wherein the cylinder body is sleeved with the rolling ring; a gap is formed between the inner wall of the rolling ring and the peripheral surface of the cylinder body, and the rolling ring is fixedly connected to the cylinder body through a plurality of elastic support plates; each support plate comprises a rolling ring connecting part welded onto the inner wall of the rolling ring and a cylinder body connecting part welded onto the peripheral surface of the cylinder body. Each cylinder body connecting part is divided into two parts in the transverse direction, and the two parts are respectively welded onto the peripheral surface of the cylinder body. The supporting structure can absorb irregular impact force generated when aggregate turns down, and the reliable connection between the rolling ring and the cylinder body is ensured.
Description
technical field [0001] The invention relates to a supporting structure of a drying cylinder of an asphalt mixture plant mixing heat regeneration equipment. Background technique [0002] In the asphalt mixture plant mixing heat recycling equipment, the drying system is indispensable in the whole equipment. The drying system includes a drying cylinder and a rolling ring welded on the outer surface of the drying cylinder. The transmission device drives the driving wheel, and the friction of the driving wheel drives the rolling ring to rotate, thereby driving the cylinder to rotate, so that the aggregate is turned over and heated inside the drying cylinder. [0003] The reliability of the connection between the rolling ring and the cylinder directly affects the quality of the product. In the prior art, the rolling ring and the cylinder body are directly welded and fixed together, but thermal expansion and contraction of the drying cylinder easily cause weld seams to appear betw...
