A ball pickup device, comprising a ball collector (1) and a pull rod (2) connected to the ball collector (1). The ball collector (1) is provided with ball inlets (3) and ball outlets (4). The ball inlets (3) are formed in the bottom of the ball collector (1) and are formed by a plurality of transverse rods (31) arranged at the bottom of the ball collector (1) in parallel at intervals. One ball inlet (3) is formed by the interval between every two adjacent transverse rods (31), and the interval between every two adjacent transverse rods (31) is smaller than the diameter of a ball. One end of each transverse rod (31) is fixedly connected to one side of a frame at the bottom of the ball collector (1), receding grooves (32) are formed in the other side of the frame at the bottom of the ball collector (1), the other end of each transverse rod (31) is a movable end and located in the corresponding receding groove (32), and the largest receding interval of each movable end is larger than the diameter of a ball. When a ball is pressed, the movable ends of the transverse rods (31) move along the receding grooves (32) to recede under the pressure of the ball, and the ball enters the ball collector (1) through one ball inlet (3); after the portion with the largest cross section diameter, connected to the corresponding transverse rods (31), of the ball enters the ball inlet (3), the movable ends of the transverse rods (31) move along the receding grooves (32) to gradually return. The ball pickup device is simple in structure and convenient to use. |
