ABSTRACT:
A vertical bale elevator to transfer bales of hay, straw or the like between the ground and a barn has an elongated frame with two opposing augers mounted on opposite sides of the frame. The frame contains a guide for the blades. The augers are mirror images of one another and rotate in opposite directions to force a bale upward and rearward within a frame. The guide is arranged to receive a bale in the bottom section and discharge the bale in the top section. The augers are powered by a single power source that can be reversed to move bales down the elevator rather than up. When operating in reverse, it is usually desirable to make changes to the guide. The middle sections are made in various lengths so that the total height of the elevator can be varied. With previous elevators, a chain rotates upward at a back and front of the elevator. These previous elevators are much more complex.
