[0002] The mixing drum is an important part of the concrete mixer truck. Its entire shape is conical at both ends and cylindrical in the middle. In the production process of the mixing drum, it mainly requires processes such as ring welding, sandblasting, and painting. In this process, the mixing drum needs to be able to rotate at a certain speed to complete the processing and production of the mixing drum. However, due to the different external dimensions of mixing drums of different dimensions, the existing ring welding, placement, sandblasting, and painting devices dedicated to the mixing drum mainly use friction wheels to drive the mixing drum rollers to rotate to drive the mixing drum to rotate, and the friction wheels are used to support the rear end of the mixing drum. Such a structure often causes the roller surface to be damaged when the roller and the friction wheel come into contact, which may cause scratches on the roller surface at the least, or damage the contact between the roller and the support wheel at the worst, making the mixing drum unable to rotate normally.
