Abstract
A feeder for livestock and the like is disclosed. The feeder has a feed receiver body for receiving and storing a flow of feed from a conveyor. A drop tube means extends from the feed conveyor into the feed receiver body, and includes at least one wall mounted for vertical motion relative to a fixed wall. When the moveable wall is in a raised position, that moveable wall and the fixed wall define a vertically oriented opening through which feed can pass from the drop tube into the receiver body. By adjusting the position of the moveable wall, the amount of feed collected in the receiver can be correspondingly changed. When a stopper valve member is drawn away from a discharge opening, the feed pile collected in the receiver body is discharged from the receiver for livestock consumption. A stopper actuator includes a flexible member connected to the stopper valve, and a rotatable windup device connected to the flexible member. When the windup device is rotated, the flexible member is wound up and draws the stopper valve away from the discharge opening.
