V-belt enwinding and wrapping type driving drum

A V-shaped belt twining and surrounding transmission drum relates to a transmission drum for a rubber belt conveyor used in mines capable of replacing the fail rubber face rapidly. The utility model is characterized in that: a spiral groove with a V-shaped cross area is equipped on the surface of the transmission drum, a V-shaped rubber belt matching the V-shaped spiral groove is twined on the V-shaped spiral groove, two ends of the V-shaped rubber belt are fixed on the drum wall's inner surface of the transmission drum's two ends by a belt-pressed plate. The utility model is hard wearing and durable, and has better transmission effect. The utility model has the advantages of rubber casting drum-thickness and durable, and has the advantages of rubber covered drum-convenience for replacing. The utility model suits the characters that heavy dust exists in the mines, the rubber face can be fretted rapidly and must be replaced in time. The utility model can be replaced in downtime thereby saving time and labor, and do not effect regular production in mines.
