[0001] The utility model relates to the technical field of feeders, in particular to a double-driving device for a belt feeder which is convenient for replacing chains. Background Art

[0002] Coal mine production has increasingly higher requirements for the mechanization level of equipment. The belt feeder used to discharge coal from the lower mouth of the coal bunker is an essential equipment in the transportation system. It is used frequently. Once a failure occurs, it will directly cause the transportation system to stagnate. In severe cases, it will affect the transportation of the entire coal flow system and even cause the mining face to stop production. Most existing belt feeders are single-drive controlled. Since the belt feeder has a long service life and is frequently started and stopped, there are many drive device failures such as motor burnout, reducer and speed regulator damage. After the equipment fails, it takes a long time to wait for the spare parts to be transported to the site for replacement, which often affects production. In addition, the existing dual-drive device requires operators to replace the chain, which is a cumbersome and time-consuming process and poses certain safety hazards.
