ABSTRACT:
A spreader for feeding and uniformly distributing grain in a bin. The spreader has a hopper to receive the incoming grain. A screw mounted in the hopper evenly spreads the grain and propels it into a chute whose discharge mouth is normally closed by a spring pressed gate, or valve. A rotary thrower blade, mounted below the chute, aids the chute to distribute the grain generally radially and downwardly uniformly in the bin. The screw, the discharge chute and the thrower are driven as a unit by a single shaft, mounted coaxially in the hopper, and rotated by a motor mounted externally of the hopper. The pressure of grain movement propelled by the screw opens the chute gate allowing grain to pass to the spreader.
