Description

Technical Field

[0001] The utility model relates to the technical field of coal conveyors, in particular to a coal conveyor capable of preventing coal powder from piling up at corners. Background Art

[0002] Coal conveyor belt, as the name implies, is a belt conveyor for conveying coal materials. It is one of the indispensable and important equipment in modern heavy industry. Coal conveyor belt not only has the advantages of high conveying efficiency and wide application range, but also can reduce the labor intensity of workers to a certain extent, reduce production costs and improve production efficiency.

[0003] In the conveyor, the coal powder will be transferred to the designated location on the coal conveyor belt. However, during the transportation process, due to the long transportation distance and the fact that the coal conveyor belt cannot be well limited, the coal conveyor belt is prone to deviation, causing the coal powder to roll and accumulate.

[0004] At the same time, in some areas where coal is easily dropped, coal powder accumulates at the bottom of the machine over time. Due to the poor working environment, it is very difficult to collect the coal powder.

[0005] In addition, the coal conveyor belt moves for a long time, and there is constant friction between the belt and the roller, which can easily generate high temperatures in a hot and humid environment. Coal powder is flammable, and there is a risk of combustion during the transportation of coal powder. Utility Model Content
