[0002] During the use of a belt conveyor, generally no special requirements are imposed on the lower belt as the return section. As long as the belt is laid at the corresponding position with load-carrying idlers, the normal use of the belt conveyor can be satisfied. However, in the case of undulating ground in the mine, according to the design requirements, it is necessary to adjust the height of the belt surface by a large amount in a short distance. As long as the upper belt surface meets the laying requirements, but the following problems may exist with the lower belt:

[0003] 1. In areas with large ground undulations, the belt surface may jump and the belt may float, resulting in collisions with the trough-shaped frame body, an increase in frictional resistance, and in severe cases, the belt may be torn, affecting the normal operation of the belt conveyor and posing a safety hazard to production;
