Abstract: An improved grain or particulate distributor includes a radially extending conveyor mounted for sweeping about the center of a bin for evenly and homogeneously distributing material therein. Discharge or sweeper bars are adjustably angularly mounted across selected areas of the conveyor for discharging grain from one trailing side of the conveyor into the bin, while an inclined surface with adjustable vanes facilitates the smooth transition of the discharged grain from the belt to the silo. Grain agitation is minimized to impede separation of fine from coarse particles. Means are provided for also distributing a portion of grain to the periphery of the silo. A chute for feeding the conveyor has a grain controlling gate responsive to the amount of grain in the chute available for feeding, and the conveyor belt has two speeds which are selected responsive to the volume of grain in the chute.
