Driving and transmission method and device for conveying belt type dumper

The invention relates to a driving and transmission method and device for a conveying belt type dumper, ribs are transversely fixed to the back face of a conveying belt at intervals, at least two longitudinal beams are fixed to the dumper, the ribs are supported on the longitudinal beams, and a structure that the conveying belt drives the ribs to do annular motion and the ribs are supported on the surfaces of the longitudinal beams to slide is formed; rib supports are fixed at conveying chain bolts; the ends of the ribs are connected with the rib supports, the heights of the rib supports are adjusted, the neutral layer of the conveying belt is adjusted to coincide with the reference circle of a chain wheel, and the conveying chain and the rib supports are fixed, so that the neutral layer of the conveying belt and the reference circle of the chain wheel are adjusted to coincide. The device has the advantages that the reference circle of the chain wheel coincides with the neutral layer of the conveying belt whe
