Conveyor for hopper bottom transportation vehicle

摘要

A conveyor is arranged to be mounted underneath a hopper bottom highway transportation truck which has two longitudinally spaced dump hoppers each with a bottom discharge opening to carry the discharged material to the side of the trailer from each of the hoppers in turn. The conveyor is thus carried between the bottom discharge openings so that it can be raised up between them during transport. From the mounting point at one side between the openings the conveyor is lowered so that its loading end is lowered and then the conveyor pivots to one side or the other so that its loading end is underneath the selected bottom discharge opening. The conveyor runs in a direction so that it lifts the material from the selected discharge opening upwardly to the mounting point at the one side for discharge to the side.

主权项

1. A hopper bottom transportation vehicle comprising:
two longitudinally spaced dump hoppers each with a bottom discharge opening; ground wheels for carrying the dump hoppers across the ground for delivery of a particulate flowable material; and a conveyor arranged to be mounted underneath to carry the discharged material to the side of the vehicle from each of the hoppers in turn, the conveyor comprising:
a conveyor frame arranged for mounting on the vehicle;a conveyor mechanism on the frame having a discharge at a first end of the frame and a feed receptacle at a second end of the frame;a first mounting component for mounting the first end of the conveyor frame at or adjacent a first side of the vehicle at a position between the two hoppers;a second attachment component assembly for releasable attachment of the second end of the conveyor frame at or adjacent a second side of the vehicle at a position between the two hoppers;such that in a transport position the conveyor frame extends across the vehicle and is carried by the mounting arrangement and the attachment assembly in a position between the two hoppers extending across the vehicle;the second attachment component being arranged to release the second end of the frame to lower from the vehicle to the ground;the first mounting component being arranged to allow up and down pivotal movement of the conveyor frame so as to allow the second end to raise and lower to the ground;the first mounting component being arranged to allow pivotal movement of the frame about a generally upright axis at the first side;such that in a first operating position the conveyor frame pivots so that the feed receptacle is located underneath a first one of the bottom discharge openings;and such that in a second operating position the conveyor frame pivots so that the feed receptacle is located underneath a second one of the bottom discharge openings.
