<p>The belt conveyor apparatus (11) comprises means which define a conveyance path (13) including a first pulley (23) and at least a second pulley (25). The endless belt member (27) is adapted for continuous travel about the pulleys (23, 25, 33, 35, 37, 39, 41, 43) and comprises a lower portion (53) which engages the pulleys and an integral upper portion (55) adapted to receive objects (83) therein at a first location (15) on said conveyance path and transport the objects to a second location (17) for discharge. The upper belt portion includes an opposed pair of longitudinally disposed crest-like members (61, 63), biased towards each other in a substantially abutting relationship. The crest-like members define therebetween a continuous, normally biased closed, channel (65) along the upper belt portion. Means (49, 51) are disposed at the first and second locations and operatively associated with the belt member for urging the normally biased together crest-like members apart in order to provide access to the continuous channel whereby objects can be received into, or discharged from the channel. Motive means (48) are in communication with the means defining the conveyance path for effecting the travel of the endless belt member about the conveyance path. The conveyance path can be configured to include travel through two or more elevations and one or more directional changes in order to convey objects above, below and/or around existing structures. </p> |
