[0047] Embodiment 3

[0048] The schemes in Embodiment 1 and Embodiment 2 are further introduced in combination with specific working modes, and details are described below:

[0049] In use, coal falls from a fixed point to the top of the conveyor belt body 1. Due to a certain height difference, a large impact force is applied to the conveyor belt body 1 at the falling point. The use of the spring 6 can reduce the impact force when the material falls. In addition, during the conveying process, the weight of the top of the conveyor belt body 1 increases, which compresses the spring 6, and the conveyor belt body 1 moves downward.
