ABSTRACT:
A material spreader for the uniform distribution of granular material beneath the spreader by broadcasting the material through outlets formed within a rotating pan. The spreader has a funnel-shaped chute to receive material and direct it into the pan under the force of gravity. The pan has a flat-bottomed surface and vertical walls with outlets formed in its corners. Vanes are provided which extend the sides of the pan in a direction away from the center of the pan, thereby increasing the horizontal velocity of the material leaving the pan outlets. Baffle plates throttle the passage of material through the outlets in the corners of the pan, aiding the momentary retention of material in the pan to assure that substantially equivalent amounts of material exit each corner of the pan. Secondary outlets of adjustable size are provided in the bottom of the pan to allow material to exit nearly vertically. The horizontal throw of the pan may be varied by changing its rotational speed and by reversing its direction.
