Background technique

Belt conveyor is the most important equipment for transshipping materials in bulk ports. It has a long operating time and a large number of operations. Its normal operation is closely related to the efficiency of bulk cargo transshipment. Since the belt conveyor runs for a long time and the materials are different, a large amount of materials are often adhered to the belt. The second-pass cleaner can scrape off the large amount of materials adhered to the belt and make the materials fall directly under the belt. Since the space directly under the second-pass cleaner is small, it is very easy to cause excessive accumulation of coal, causing the coal to contact the belt and then wear the belt. It is also very inconvenient to clean during operation, and it also brings great safety risks to the cleaning personnel. Therefore, this application studies a semi-automatic coal cleaning device for the head hopper of a belt conveyor to effectively clean the accumulated coal, ensure personnel safety and protect the belt.
