[0002] Belt conveyor is the abbreviation of belt conveyor. Belt conveyor uses continuous or intermittent movement of conveyor belt to transport various items of different weights. It can transport various bulk materials, as well as various cartons, packaging bags and other small-weight single-piece goods. It has a wide range of uses. Among them, three-roller conveyor belt conveyors are often used underground to transport some materials underground. However, in existing conveyor belt conveyors, the three rollers are all fixed on the frame, so that the concave surface formed between the three rollers cannot be changed.
