Split shaft aureole rise direction-exchanging apparatus

The utility model provides a shaft-separation type smooth-wheel head-risen direction-change device, the problem to be solved is that one shaft is adopted to be simultaneously used as the rotary hinge shaft of a cantilever and the support shaft of a chain wheel. As the structure integrally adopts one shaft and the span of support points is larger, the diameter and the length of the shaft are caused to be bigger, the weight of the shaft is caused to be higher, and the economic property of the shaft is caused to be less. At the same time, as limited by the structure, a material guard wall must be arranged above a discharge rubber belt machine, or the way of digging trench is adopted to place the rail and the rubber belt machine below a bin. The key point of the utility model is that a chain wheel group of a smooth-wheel which takes a direction-change action is arranged at the inner sides of two hinge points of the root part of the cantilever of a side-type scraper material-taken machine, the chain wheel group is
