See full text

A tennis ball pick-up cart comprises a chassis including a pair of driven wheels and a pair of steering wheels. A ball collection case is coupled to the chassis. A ball pick-up mechanism includes a concave ball guiding plate laterally placed under two vertical side plates. The ball pick-up mechanism also includes a fixing shaft and a rotating shaft each laterally extending between the vertical side plates. Synchronous belt pulleys are provided on the fixing shaft and the rotating shaft. Two synchronous belts are assembled with two of the synchronous belt pulleys. Laterally placed ball-moving plates are evenly distributed on an outer surface of each of the synchronous belts. Each of the ball moving plates includes a ball moving surface perpendicularly connected to the outer surface of each of the belts. An electric motor drives the driven wheels and the rotating shaft.
