Abstract

The invention discloses an air-compression type tennis ball serving machine with a high initial velocity. The air-compression type tennis ball serving machine comprises a ball collecting box, a ball inlet pipeline and an adjusting rod, wherein moving wheels are mounted on the left side of a support leg, an air compressor is arranged above an air storage tank, a barometer is mounted on the left side of the air compressor, a second drive motor is arranged above the barometer, the top end of the adjusting rod is connected with a fixing ring, a ball outlet is formed in the fixing ring, and the right side of the fixing ring is connected with a bellows. The air-compression type tennis ball serving machine with the high initial velocity is provided with ball handling sticks, tennis balls in the ball collecting box can be taken out one by one in sequence, and the problems that a ball handling pipeline is easily blocked and gets stuck usually and the like are solved; an elastic plate is fixed in the ball handling pipeline and enables the tennis balls to accumulate elastic potential energy in the bent position of the elastic plate, so that the tennis balls have the higher initial velocity when served; compared with an ordinary electric roller type ball serving machine, the ball serving machine adopts the air compression principle, serves balls more quickly and doesn't easily get stuck and the like.

Description

technical field [0001] The invention relates to the technical field of sports machinery equipment, in particular to an air-compressed tennis ball machine with high initial velocity. Background technique [0002] With the continuous popularization of tennis, tennis ball machines are becoming more and more popular. At present, the most mainstream tennis ball machines rely on two runners to squeeze the tennis balls, so that the tennis balls are played. The function falls into the serving part by itself. If two tennis balls are placed side by side at the entrance of the pipe, it will be blocked and stuck. When the machine is stuck, the user is often on the other side of the tennis court, and it is very inconvenient to adjust. Squeeze-type serving will produce greater pressure and deformation on tennis balls. Ordinary tennis balls are prone to deformation and cracking after being squeezed for a long time. Therefore, when using this type of tennis ball machine, it is necessary to ...
