Problems solved by technology

[0002] As an important sport, tennis is loved by many people, especially for those professional athletes, who have to practice a lot every day. In the existing tennis training, a coach can only accompany one athlete. The training method not only increases the amount of exercise for the coach, but also reduces the effect of the athlete's training. However, in the existing ball server, the landing point, the speed of the ball, the angle of the ball, and the speed of the ball cannot be adjusted. There are rules to follow, so it is difficult for such a server to improve the level of athletes, and it is also difficult to meet the training requirements of athletes, and the existing server uses the principle of counter-rotating double wheels to work. Accelerate the wear of the soft hair on the surface of the tennis ball, thereby reducing the service life of the tennis ball, thereby increasing the cost of player training

Embodiment 1

[0021] Embodiment one: if figure 1 -Shown in 4 and 7, a kind of tennis ball serving device comprises ball frame 1 and compressor 9, wherein is provided with conical platform 2 at the bottom center of described ball frame 1, and its purpose is to allow tennis ball to enter from Ball hole 3 enters goal tube 4, is provided with controller in described conical platform 2, is provided with some goal holes 3 around described conical platform 2, below each described goal hole 3 A goal tube 4 is arranged horizontally, a push rod 6 is arranged at the end of the goal tube 4, a "T" shaped push plate 5 is arranged at the front end of the push rod 6, and a tennis ball can be moved by the push rod 6 after one stretch. From the goal tube 4 to the pressurized tube 10, and the push plate 5 of the "T" shape can play a blocking role in the telescopic process of the push rod 6, preventing multiple tennis balls from entering at one time, and the end of the goal tube 4 Connected with a pressurized...

Embodiment 2

[0024] Embodiment two: if figure 1 , 2 , 3, 5, and 7, based on Embodiment 1, a serving tube 15 is provided between the pressurized tube 10 and the fixed plate 16, and a serving tube 21 is provided in the serving tube 15, The outlet end of the pressurizing tube 10 is connected with the flexible pipe 18 through the serving tube 21, the shapes of the serving tubes 21 are different, and its purpose is that when the tennis ball passes through the serving tube 21 of different shapes, the The speed, the angle of serving and the direction of rotation will all change, and the said serving tube 21 has an "S" shape, the purpose of which is to allow the tennis ball to change the angle of the ball when it reaches the hose 18 to improve the training effect. Difficulty, there is also the helical structure of the serving tube 21, the purpose of which is to allow the tennis ball to obtain a greater rotational speed in the serving tube 21, so that the ball can be sent with a high level of rota...

Embodiment 3

[0025] Embodiment three: as figure 1 , 2 , 3, 6, and 7, based on Embodiment 2, a fixed disc 23 is provided at the outlet end of the pressurized tube 10, and a perforation is provided on the fixed disc 23 corresponding to the pressurized tube 10 , a butt plate 22 is provided at the upper end of the serving cylinder 15, and a through hole is provided on the butt plate 22 corresponding to the perforation. The tube 21 and the pressurizing tube 10 can be combined arbitrarily, so that the landing point of the tennis ball and the speed of the ball become more diversified.

[0026]Its working principle is: at first some required parameters have been set in the controller, and the technical control required by the present invention can be realized in the prior art. When athletes are training, if they are practicing with the coach , the coach can manually operate the control panel, and choose the difficulty of serving according to the actual training situation of the athlete. If the a...
