Belt conveyors are widely used in enterprises, especially in the building materials industry, where they are almost an essential main conveying device. Therefore, the operating efficiency of belt conveyors is directly related to the production of the entire enterprise, as well as its economic performance. The conveyor belt is the main component of a belt conveyor, and therefore, how to reduce belt wear and extend its service life becomes the key issue. When conveyor belts transport materials, especially larger lumpy materials or those with high humidity, chute blockage often occurs. Once the chute becomes blocked, material will fill the feed hopper in a very short time, resulting in friction between the material and the conveyor belt. This causes severe wear or even tearing of the conveyor belt, leading to losses for the company. In actual production, through numerous modification experiments, we believe the following solutions can effectively extend the service life of conveyor belts: (1) Shorten the rear baffle of the feed hopper on the belt conveyor and add an auxiliary chute, so that the distance between the rear baffle of the feed hopper and the drive drum is greater than the maximum particle size of the material being conveyed (usually 1.5 times the maximum particle size is sufficient). (2) To enable the belt conveyor to stop promptly when the chute becomes blocked, a grid-shaped flap is installed in the auxiliary chute (it is designed in a grid pattern to prevent dust accumulation from affecting its functionality). The flap is connected to a lever, and at the other end of the lever there is a set of weight-adjustable counterweights; the weight of these counterweights should be slightly greater than that of the flap (the exact weight can be determined based on specific circumstances). The end of the counterweights is connected to a control switch (the type and model of the switch should be chosen according to specific conditions), so that the switch can be connected to the conveyor’s shutdown control circuit. When the chute of the belt conveyor becomes blocked and material accumulates, under the action of the drive drum, the material falls into the secondary chute from above the rear baffle of the feed hopper, thereby pressing on the grid flap. Through the action of the lever, the weight at one end will activate the switch, quickly stopping the belt conveyor in order to reduce friction between the conveyor belt and the material, thereby preventing excessive wear or tearing of the belt. This solution has been used in actual production, and its effects are very noticeable.
