CONVEYOR DEVICE AND CONVEYOR BELT TO BE USED FOR THE SAME

PROBLEM TO BE SOLVED: To provide a temporary conveyor device capable of supporting a conveyor belt at its required places with intermediate supporting columns erected between a head portion and a tail portion, enabling the conveyor belt to be held in a good trough shape even in an area between the intermediate supporting columns. SOLUTION: The temporary conveyor device comprises the conveyor belt endlessly applied on the head portion and the tail portion with the intermediate supporting columns erected between the head portion and the tail portion and supported at its required places between the head portion and the tail portion with the intermediate supporting columns. The conveyor belt 16 to be used for the same comprises an upper cover rubber 48, a lower cover rubber 50, and a reinforcing core canvas 52 embedded therein. The core canvas 52 has layers being less in number at a central portion X in the cross direction of the conveyor belt 16 and being stepwise greater in number toward both ends Z, and is more flexible at the central portion X of the conveyor belt 16 than at both ends Z.
