At present, in the transportation of bulk materials, especially the corrugated sidewall belt conveyor. It main body consists of the launching rack, the vertical or inclined lifting rack, the upper horizontal rack, the head rack, the large inclination belt and the large inclination belt driving device. The large dip belt starts from the tail of the lower horizontal section and passes through concave arc section, vertical or inclined lift section, upper horizontal section and head frame to drive the material transportation from the bottom to the top. During the conveying process, due to the vibration, the relative movement of the material and the steering of the high-inclination belt, the design, installation problems and other comprehensive problems, the material is easy to fall from the high-inclination conveyor belt. Generally, the material will be scattered on the ground of the upper or lower horizontal section. The material scattered in the upper horizontal section is easier to handle and can be returned to the funnel by ordinary scraper conveyors or other methods. The scattered material in the lower horizontal is usually cleaned by hand. This kind of manual cleaning workload is large and the working environment is quite harsh and the amount of the spilled material cannot be returned to the large inclination belt in time, it will affect the throughout and thus effect the while process system.

The purpose of the utility model is to overcome the above shortcomings and to provide a material return device of the corrugated sidewall belt conveyor that can effectively return all the scattered materials from the conveyor to the original large inclination belt. Its characteristics are as follows: the frame is c-type structure, which is composed of lower horizontal segment, concave arc segment, vertical or inclined lifting segment, convex arc segment and upper water segment end to end. The tailstock is set at the right end of the lower horizontal segment and the head stock is set at the right end of the upper horizontal segment. The materials scattered by the corrugated sidewall belt conveyor are collected by the material collecting tank and material collecting bucket of the c-type return device of the utility model, they are deflected into the high-dip belt. The material also passes through the lower horizontal segment, concave arc segment, vertical or inclined lifting segment, upper convex segment and upper horizontal segment under the belt of large inclination angle. Finally, under the action of gravity, it slides down to the feeding pipe and then returns to the large inclination belt of the corrugated sidewall belt conveyor.
The utility model is beneficial in that the materials scattered by the corrugated sidewall belt conveyor can be returned to the original corrugated sidewall belt conveyor through the c-type material return device, which does not need manual cleaning and reduces the manual cleaning workload, and because the c-type recycling device is fully enclosed, the dust does not affect the whole environment, reducing the pollution to the environment and at the same time, all materials can be all evenly transported out, ensuring the requirements of corrugated sidewall belt conveyor for throughout of the whole process system.
