摘要: A pneumatic ball gathering system that clears tennis balls from a court using air supplied to at least one discharge nozzle with optional intervening valves forming structure is typically disposed underground and selectively raised clear balls. In implementation, the located along side edge of court. an alternate may be under net configured direct in both directions away net. collection trough formed slope cause collated roll downward therein opposite nozzle. An mechanical conveyor placed move collected predetermined location. vertical raises for into appropriate container. The used facilitate drying after rain.
