ABSTRACT:
A belt curve conveyor has a number of guide wheel units provided in proximity to the peripheral part of a fan-type belt slung over between tapered end pulleys of a drive side and a driven side, wherein the guide wheel units comprise first and fourth guide wheels are supported by a holder member secured to a base and second and third guide wheels supported by a bracket, a rotary lock part is provided at inner center of the holder member around an axis of rotation of the bracket while a keyhole is formed at an outer surface to be engaged with a key part arranged on a detachable lock handle so that the second guide wheel and the third guide wheel become separated from an inner surface of the belt by inserting the key part of the lock handle in the lock part, pressing and turning the lock to rotate the bracket in the same direction by 90 degrees, which enables the belt to be removed.
