Abstract
A ball pickup device is provided, comprising a ball collector and a pull rod connected to the ball connector. The ball collector has ball inlets formed at the bottom of the ball collector and formed by transverse rods arranged at the bottom of the ball collector in parallel at intervals, and one ball outlet is formed by the interval between every two adjacent transverse rods. Each interval is smaller than the diameter of a ball. One end of each transverse rod is fixedly connected to the ball collector, and the other end is a movable end and located in the corresponding receding groove. When a ball is pressed, movable ends move along receding grooves to recede under the pressure of the ball, and the ball enters the ball collector. After the ball enters the ball inlet, movable ends move along receding grooves to gradually return.
