Abstract
A trailer assembly is disclosed for receiving, transporting and discharging flowable bulk material. The trailer assembly includes a pair of opposing generally vertical side walls which are secured to a frame member and converge downwardly and inwardly. The side walls are joined by a front end wall and a rear wall to define a bin having an open floor. A conveyor is provided as a floor for the bin with the conveyor extending beneath the side walls and having a width greater than the distance between bottom edges of the side walls and positioned closely adjacent to the bottom edges of the side walls. The conveyor includes a pair of opposing endless chains which are mounted about sprockets with the chains connected by cross members. Flexible conveyor belt sections are provided secured to the cross members at a leading edge of the belt sections with trailing edges of the belt sections free to overlap leading edges of successive belt sections. Upper tracks of the chains are supported by a support bar secured to the frame member and having a vertical portion which extends between chain links to engage link pins in supporting rolling engagement.
