摘要

A volleyball spike training system comprises a ball holder and an optional net. The training holder comprises a wheeled chassis supporting a vertical stanchion projecting upwardly that supports a hopper and a ball feeding apparatus. The stanchion includes a crank system for vertically adjusting telescoped stanchion segments. Balls dropping from the hopper travel by gravity down an inclined ramp at the top of the frame towards a discharge throat. Balls travelling down the ramp are indexed by a Z-shaped lever that serially separates them. A pair of downwardly projecting hands, one fixed and one pivoted, receive dropping balls and temporarily hold them for shooting. The pivoting hand controls the indexing lever to jam successive balls when the device is loaded. When a ball is shot and removed from between the feed hands, another ball is freed by the indexing lever to automatically drop into a shooting position between the hands.
