ABSTRACT:
An apparatus for providing uniform distribution of aggregate material has a rotatable hopper mounted on a support frame to receive aggregate material from an apparatus supplying aggregate material. Attached to the rotatable hopper, and in communication with a discharge opening of the hopper, is a chute extending downwardly and angularly outwardly from the axis of rotation of the hopper. The chute includes a baffle which responds to the gravitational force applied by the flow of aggregate down the chute to cause rotation of the hopper and thereby provide for uniform spreading of aggregate beneath the hopper. A modified version includes a first hopper pivotally mounted on the support frame in a manner to receive aggregate from the supply apparatus and a second hopper rotatably mounted beneath the first hopper with the chute attached to the rotatable hopper to receive aggregate from the rotatable hopper and cause rotation of the rotatable hopper. A further modification includes a support frame attached to a conveyor in a position to receive aggregate material from the conveyor. The chute may include two sections slidably connected and having a winch adaptable to control the length of the chute. A wind vane may be positioned on the rotatable hopper to react to wind flow to provide smoother rotation of the rotatable hopper.
