<p>A feeder (25) for livestock and the like is disclosed. The feeder has a feed receiver body (31) for receiving and storing a flow of feed from a conveyor (23). As shown in FIGS. 2, 3 and 4, a drop tube means (51) extends from the feed conveyor (25) into the feed receiver body (31), and includes at least one wall (65) mounted for vertical motion relative to a fixed wall (55, 57). When the movable wall is in a raised position, that movable wall (65) and the fixed wall (55, 57) define a vertically oriented opening (64) through which feed can pass from the drop tube (51) into the receiver body (31). By adjusting the position of the movable wall (65), the amount of feed collected in the receiver (25) can be correspondingly changed. When a stopper valve member (40) is drawn away from a discharge opening (44), the feed pile collected in the receiver body (31) is discharged from the receiver (25) for livestock consumption. A stopper actuator (47) includes a flexible member (49) connected to the stopper valve (40), and a rotatable wind-up device (48) connected to the flexible member (49). When the wind-up device (48) is rotated, the flexible member (49) is wound up and draws the stopper valve (40) away from the discharge opening (44).</p> |
