At present, the transportation of various ores and raw materials is basically realized by a belt conveyor, and the belts are generally connected through a funnel chute device. Most of raw materials are bulk materials, the water content is often high due to weather and the like, the materials are easy to adhere in a funnel chute, so that friction resistance among material particles is increased, circulation is hindered, and in addition, the funnel chute inclination, surface smoothness and the like are caused, the materials are easy to form arching and blocking in the funnel chute, so that the materials are accumulated; the lack of effective detection means on site eventually causes the materials to be piled up and overflow the hopper, so that large-area material scattering is formed, the stop of production is forced, and sometimes even equipment is damaged. At present, the raw material factory generally adopts manual inspection, finds that the putty is stopped immediately, manually takes three meters and four meters of steel drills to dredge, is large in workload and severe in environmental hazard, and the hopper chute of the raw material factory is huge in quantity, inspection workers are tired to run, and the situation that the material putty is scattered often occurs due to untimely inspection, so that more manual operation is needed to clean the scattered material in the follow-up process, and time and labor are wasted.
