ABSTRACT:
An aggregate carrying body has an output area defined at its bottom, a metering beam located above this output area, that can be elevated (and lowered), this metering beam to control and assist the flow of aggregate material to the output area. In the preferred embodiment of this invention, the output area comprises a conveying floor. A conveyor is disposed at the bottom of body and extends beyond the rear of the body through a transverse opening in the rear end wall of the body. Aggregate material in the body flows to the output area and the conveyor is then operable to remove the aggregate material from the body rearwardly and through a transverse opening at the rear of the body.
