TROG FÜR LUFTFILMFÖRDERER

摘要

Disclosed is a belt conveyor capable of greatly reducing friction resistance between side portions of a belt and troughs, comprising troughs ( 5 ), a belt moving above the troughs ( 5 ) along a longitudinal direction thereof, belt bending members ( 12 ) provided outside on both sides of the belt in the width direction so as to be located upstream of an entrance ( 5 a) of the troughs, for abutting with both side portions of the belt to be bent upwardly, load cells ( 14 ) for detecting a reactive force exerted by the belt with which the belt bending members ( 12 ) make contact, guide rails ( 16 ) engaged to cause the belt bending members ( 12 ) to be displaced to be fixed at a desired position so as to bend the side portions of the belt or restore the bent belt, and rails ( 20 ) for moving the guide rails ( 16 ) along the longitudinal direction of the belt.
