Energy-saving and consumption-reducing belt conveyor

A belt conveyor, comprising a rack, and a drive roller, a redirection roller and supporting rollers which are supported on the rack, wherein the supporting rollers are divided into an upper supporting roller (1) and a lower supporting roller (2); an upward moving section and a downward moving section of the belt are supported by the upper supporting roller (1) and the lower supporting roll (2) respectively; the upper supporting roller (1) is installed on a first support, and the lower supporting roller (2) is installed on a second support; the first support comprises a first cross beam (4) and a plurality of first supporting racks (5); and the second support comprises a second cross beam (6) and second supporting racks (7). The first supporting racks (5) are respectively arranged alternately on the first cross beam (4), and the second supporting racks (7) are respectively arranged alternately on the second cross beam (6). The present belt conveyor may achieve three points on different dimension lines forming a face, thereby increasing effective contact points, enlarging a touch surface, reducing the weight of the supporting rollers, reducing friction, and reducing damage to the supporting rollers.
