Tennis Ball Pick-Up Cart
First Claim
1. A tennis ball pick-up cart, comprising:
- a chassis including a pair of driven wheels and a pair of steering wheels;
a ball collection case including an open top coupled to the chassis;
a ball pick-up mechanism including two vertical side plates and a ball guiding plate, the ball guiding plate including a concave curved surface laterally placed under the two vertical side plates, the ball pick-up mechanism further including a fixing shaft laterally extending between the two vertical side plates, a rotating shaft laterally extending between the two vertical side plates, a pair of synchronous belt pulleys provided on each of the fixing shaft and the rotating shaft, each belt pulley being placed inside the two vertical side plates, two synchronous belts each assembled with two of the synchronous belt pulleys on the same side, and laterally placed ball-moving plates evenly distributed on an outer surface of each of the synchronous belts, each of the ball-moving plates having a ball-moving surface perpendicularly connected to the outer surface of each of the synchronous belts; and
an electric motor coupled to the chassis, the electric motor including an output shaft connected to a wheel shaft of the two driven wheels and also connected to the rotating shaft of the ball pick-up mechanism.

Abstract
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.
