ABSTRACT:
A spiral chute device, especially for use in conveying seed materials to storage chambers. The spiral chute device is employed for guiding the seed material downwardly in the storage chamber to prevent the seed material from undergoing free fall which could lead to cracking thereof. The device is, preferably, suspended from the top wall of the chamber and has a hopper at the top with an upwardly opening spiral chute extending downwardly therefrom to near the bottom of the chamber. The device includes a center post telescopically engaged by a guide member at the center of the bottom wall of the chamber and the device can be moved laterally in the chamber by disengaging the lower end of the post from the guide member. When the device is disengaged from the guide member and swung laterally in the chamber, the bottom of the chamber is exposed and seed material therein can then be swept into a discharge channel formed in the bottom wall of the chamber whereby substantially all the seed material can be removed from the chamber.
