Description

Technical Field

[0001] The invention relates to the technical field of coal conveyor belt protection devices, in particular to a protection device for preventing longitudinal tearing of a coal conveyor belt. Background Art

[0002] The coal conveyor belt is an important coal transportation equipment in thermal power plants, coal mines and other factories. It is usually composed of a conveyor belt, a drive device and a supporting structure. Its main function is to transport coal from one location to another. When the coal conveyor belt is used in a thermal power plant, its stability during use is directly related to the overall operation of the power plant. When the coal conveyor belt fails, it will cause a decrease in the power supply of the entire plant, and surrounding users will also be affected, and even some production areas may be unable to produce.

[0003] However, in the prior art, since the distance between the front edge of the coal drop pipe and the belt surface is small, and the buffer rollers under the belt are distributed at intervals, the natural bearing capacity strength is uneven. When the single-side length of the transported material exceeds this distance, large pieces of material are easily stuck between the front edge of the coal drop pipe and the belt, and the belt is strongly squeezed to cause tearing. At the same time, when foreign objects fall into the coal pipe and the longitudinal size of the foreign objects is greater than its passing capacity, the foreign objects will be stuck in the lower part of the coal drop pipe. When the belt moves forward, the pressure between the foreign objects and the belt will increase, which will also cause scratches on the belt. Summary of the invention
