Claim:
1. A containment vehicle with a material expeller for spreading bulk material from the containment vehicle, the containment vehicle comprising: at least one rotatable shaft revolvable about a first axis; a first set of paddles in a substantially vertically planar position extending from the rotatable shaft, each paddle having a first end and a second end, wherein the paddle extends along its length from the first end of the paddle to a second end of the paddle; wherein each of the paddles in the first set of paddles pivots at the first end of the paddle about a second axis parallel with and radially spaced from the first axis of the rotatable shaft, and wherein each of the paddles in the first set of paddles swings freely relative to the second axis, and wherein the axis about which the rotatable shaft is revolvable is substantially vertically aligned relative to the containment vehicle, and wherein the containment vehicle is provided with an active floor adapted to support bulk material on a substantially planar moving top surface of the active floor, the active floor in the form of a conveyor belt for moving the bulk material on the moving top surface of the active floor and the top surface of the active floor in a first direction towards the at least one rotatable shaft, and wherein the first set of paddles is arranged in vertical alignment above a plane containing the top surface of the active floor and a second set of paddles is arranged in vertical alignment below the plane containing the top surface of the active floor, such that the bulk material will fall into the second set of paddles as the active floor is moved in the first direction, and wherein at least one of the paddles has a center of gravity closer to the second end of the at least one paddle than the first end of the at least one paddle.
