Description

Technical Field

[0001] The utility model relates to the technical field of dust cover, in particular to a dust cover for a coal mine conveyor belt. Background Art

[0002] A coal mine refers to an area where humans mine coal resources in coal-rich mining areas. It is generally divided into underground coal mines and open-pit coal mines. Generally, after coal mining is completed, the coal is transported by a conveyor. In order to prevent coal dust from flying, dust covers are often welded on the conveyor for protection. However, after the welded dust covers are damaged after long-term use, they are often inconvenient to replace. The entire dust cover needs to be disassembled, and if the conveyor belt of the conveyor is damaged, the dust cover also needs to be disassembled, which greatly increases the maintenance cost. In addition, if the coal dust content in the dust cover is too high, it will also increase the risks of fire, explosion and equipment wear.

[0003] Among them, publication number "CN220033059U" discloses "a dust cover for a coal mine conveyor belt". This dust cover provides an idea of ​​setting a dustproof device and a connecting device from the aspect of easy disassembly, and has high practicality. However, this dust cover still has certain shortcomings in actual use. Although this dust cover achieves the purpose of easy disassembly through many structures, this dust cover adopts a closed dustproof type, that is, after the installation is completed, an enclosed space will be formed in the dust cover, which will easily accumulate coal dust. When the coal dust concentration in the dust cover is too high, there will be a safety hazard, and its installation method adopts more bolt fixing methods, so the installation and removal of the dust cover still requires more time and labor, and the cost is high. Therefore, the utility model provides a dust cover for a coal mine conveyor belt. Utility Model Content
