Therefore, a plurality of protective devices are additionally arranged on the belt conveyer at present, and play a certain role in the production process. However, because the coal production environment is relatively severe, machine parts are easy to rust and fail, and phenomena of missing report and false report often occur, so that no reliable technology is available at present, and common accidents such as belt longitudinal tearing, coal piling at a feed bin opening, downward adhesive tape overspeed and the like can be completely solved. Each production unit mainly relies on manual inspection to find problems, but accidents cannot be avoided due to factors such as insufficient personnel experience, fatigue operation, vacancy, omission and the like, and meanwhile, the labor cost is greatly increased.
In order to reduce the occurrence of longitudinal tearing accidents of the conveying belt, a plurality of anti-tearing protection devices have been researched at home and abroad, and a contact type detection system and a non-contact type detection system are mainly distinguished according to types. The development points of the belt conveyor are developed based on the condition of the torn belt, for example, rod type detection, linear detection, swing carrier roller detection and the like are based on the fact that a foreign matter penetrates through the belt instantly and then triggers a detection device, but in the actual situation, the foreign matter such as an anchor rod cannot penetrate through the belt instantly but is drawn through slowly, at the moment, the belt is seriously damaged, and even if the detection result is detected, the significance is lost. The material leakage weighing detection is that the limit switch is actuated to send out an alarm signal or stop the machine when the material leaked from the crack of the through conveying belt reaches a certain weight. However, most of belts are overlapped and closed instantly after being torn, no material leaks, even if the materials leak, the materials are scattered particles, and the weight required by detection cannot be achieved.
