Disclosed is an extendible conveyor structure (10). Structure (10) comprises a main frame (11) supported above a ground surface by way of wheels (20). Main frame (11) comprises a number of vertical members (22) and cross-members (18) extending therebetween. Main frame (11) further comprises a number of longitudinal members (23). Either fixed to main frame (11) or rollably supported thereby is a sub-frame (14) to support a conveyor belt (16). Rollably supported to sub-frame (14) is a pair of movable sub-frames (12, 13). The conveyor belt (16) spans all three sub-frames (12, 13 and 14) and is supported by rollers (15) or alternatively by troughing plates or a combination of both. The respective sub-frames (12, 13 and 14) may be manually or automatically extended between a loading zone and a discharge zone as required. Upon activation of the conveyor drive arrangement (19), the conveyor belt (16) is set in motion and bulk materials will pass from extended sub-frame (12) onto the belt at sub-frame (14), and from sub-frame (14) onto the belt at sub-frame (13). The bulk materials will then be delivered at the discharge end. |
