Abstract
There is disclosed an endless conveyor having a foldable framework and comprising a supporting structure (3), a tail conveyor framework (1) which is hingedly connected at one end (2) to the supporting structure (3), a head conveyor framework (6) is hingedly connected to the other end (5) of the tail conveyor framework (1), the tail and head conveyor drums (4, 7) mounted on tail and head conveyor frameworks respectively and around which an endless belt (8) is taken, and at least one supporting link (10) hingedly connected at one end (11) to the supporting structure (3) and at the other end (9) to the head conveyor framework (6) at a point adjacent to the hinged connection (5) of the tail conveyor framework (1) to the head conveyor framework (6). The arrangement of the supporting structure (3), the tail conveyor framework (1), the head conveyor framework (6) and the supporting link (10) is such that they form a four-bar-type linkage having proportions such that when the two conveyor frameworks (1, 6) are aligned end to end, they are constrained to slope upwardly, and an actuator is coupled with the four-bar linkage and is operable to alter the angular relationships between adjacent m…
