Description

Technical Field

[0001] This utility model relates to the field of belt conveying technology, specifically to a dust control system for a coal conveying belt machine. Background Technology

[0002] Belt conveyors are widely used in coal transportation due to their long transport distances and high conveying power. As an intermediary between roadways and between underground and surface areas, belt conveyors are one of the most important pieces of equipment in coal transportation. Long-distance belt conveyor systems typically consist of multiple sections of different lines, and during operation, malfunctions such as deviation, slippage, longitudinal tearing, material accumulation, and belt breakage may occur.

[0003] Intelligent coal mining has greatly improved coal mining efficiency, but it has also put forward new requirements for the stability of transportation equipment. During the operation of belt conveyors, due to factors such as the moisture in coal slime and the impact of coal slag, the crushed coal slag or coal slime will stick to the conveyor belt. When the amount of coal stuck together is large, it will cause the conveyor belt to run off track and other faults. This will have a significant impact on the operation of the conveyor belt, thereby slowing down the overall transportation efficiency and even causing casualties. Utility Model Content
