The invention relates to a tennis ball pick-up device, which effectively solves the problems of cumbersome operation, large volume and low ball pick-up efficiency of the existing tennis ball pick-up equipment; The first connecting rod, the ends of the two first connecting rods are hinged to form a rectangular frame structure through two sets of connecting parts, the connecting parts include a horizontal support rod in the left and right directions, and each of the two ends of the support rod is hinged with a movable The second connecting rod rotates in the horizontal plane, the free ends of the second connecting rod are hinged with the corresponding ends of the first connecting rod respectively, and an electric push rod whose axis is perpendicular to it is arranged on the top of each support rod, two electric push rods The fixed ends are fixedly connected to each other, and the protruding ends are respectively connected to corresponding support rods through vertical rods.
Description
technical field [0001] The invention relates to the field of ball picking equipment, in particular to a tennis ball picking device. Background technique [0002] Tennis will be equipped with and use a ball machine during the single-player training process. The ball machine will serve intermittently. The trainer will return the ball sent by the ball machine to the side of the machine. After a period of time, there will be many tennis balls scattered on the ground on the side of the machine. It is not big and the tennis balls are concentrated on the side of the serving machine. On the less concentrated side, there are more than ten or twenty per square meter. Due to the small size and large number of tennis balls, it is very inconvenient to pick up the ball alone. The traditional ball picking equipment has a cage. Ball picking machine and ball picking cart, the cage ball picking machine realizes that the tennis ball is squeezed into the ball cage from between the two stirrups ...
