In order to improve the backwardness of the coagulant supply in the coal mine, a new type of concrete mixer used in underground coal mine is designed, and the key technology in the design process of the new type of concrete mixer truck is described, which is restricted by the height of the underground mine roadway. The concrete transport volume is the same as the mixing truck meets the driving condition of the roadway. The sample needs to meet certain indicators. The design scheme of the whole vehicle fully considers the passing of the passing of the whole vehicle, the height of the dump in the tank, the filling rate and the sealing of the tank mouth, and gives the design scheme. The multi-function bearing(MFB) platform is designed, which can quickly replace the working mechanism and realize the multi-use of a machine. In this way operation is realized.
