Use method of belt conveyor, carrier roller assembly and belt conveyor

The invention discloses a use method of a belt conveyor. The use method of the belt conveyor comprises the following steps that S1, feeding is carried out on a tiled belt located on the upper layer; S2, the belt is closed upwards to form a pipeline; S3, the belt is tiled and carries out unloading; S4, the belt is wound to the lower layer; S5, the belt is closed upwards to form a pipeline; S6, thebelt is tiled and wound to the upper layer, and the step S1 is carried out. According to the use method of the belt conveyor, the belt is closed towards the work face when located on the upper layer,the belt is closed towards the back face when located on the lower layer, that is, the belt is closed twice in each period, the belt cannot be curled, and therefore the diameter of the belt pipeline can be prevented from becoming small, and belt pipeline leakage is avoided. The invention further discloses a carrier roller assembly and the belt conveyor. 本发明公开了一种皮带机的使用方法，包括如下步骤：S1：向处于平铺状态、且位于上层的皮带上料；S2：使所述皮带向上合拢为管道；S3：使所述皮带
