[0002] A concrete mixer truck is a special truck used to transport concrete. As one of the key components of the mixer truck, a certain amount of concrete will inevitably accumulate in the feeding hopper during use. If it cannot be cleaned in time, the concrete will accumulate on the inner wall of the hopper, reducing the cross-sectional area of the feeding port, easily causing blockage (jamming) of the flow channel, reducing the feeding performance, and at the same time causing corrosion to the metal surface of the feeding hopper. In severe cases, it may even cause damage to the feeding hopper and shorten the service life of the components.
