CA 2197132

A conveyor for particulate material of the type including a tube with a belt running through the tube and defining a return run of the belt outside the tube provides a folding action by which the length of the tube can be reduced by folding an upper portion back against a lower portion. The folding action is actuated by a hand crank which drives a chain wheel connected to a pivot pin carrying the upper portion. The pivot pin is mounted to one side of the tube which is opposite to the return run of the belt. In order to provide an extension portion of the return run which can be released to provide the length necessary for the folding action, the return run passes over a pair of rollers to form a serpentine section of the return run at the fold line of the tube. Each of the rollers is carried on a respective one of the upper and lower portions on opposite sides of the fold line to release the serpentine portion as the folding action is effected.
