Description

Technical Field

[0002] Coal mines refer to places rich in coal resources, which are generally divided into underground coal mines and open-pit coal mines. Chains are needed to realize the mechanical transmission of mechanical equipment for coal mining. Chains are processed and transported by conveying devices during the production process. Some chain processing and conveying devices include conveyors. Anti-drop plates are installed on the conveyors. The conveyors are started by control elements. The conveyors use their own belts to utilize contact friction to process and transport the coal chains. Anti-drop plates are used to prevent the coal chains from falling from the conveyors during the processing and transportation process. However, when the coal chains are processed and transported, the single coal chains are placed on the conveyors irregularly, resulting in the coal chains themselves being entangled and disordered during the transportation process, which is not convenient for subsequent equipment to process them.
