[0002] Volleyball is one of the ball sports. The existing volleyball brings great fun to people in daily life, and volleyball has become a common sport. With the development of science and technology, sports training is gradually combined with modern science, so that athletes can improve their abilities more quickly and effectively with the assistance of science and technology. In the training process of volleyball, volleyball serving machines are an indispensable sports equipment. Volleyball serving machines are mainly a device that hits volleyballs to facilitate people's training.

[0003] When the existing volleyball serving machine automatically scores a goal, the volleyball can move in a large range, resulting in inaccurate launch force and angle when the volleyball is launched. For example, the patent with publication number CN205995003U discloses a volleyball fixed-point serving machine, which relates to the field of sports equipment. When using the volleyball fixed-point serving machine, the angle between the serving barrel and the ground can be adjusted first, and then the adjustment rope can be tied to the upper adjustment ring and the lower adjustment ring respectively to fix the angle between the serving barrel and the base. Wrap the volleyball with a wrapping sheet, and stuff the wrapping sheet and the volleyball into a serving tube, pull the pull ring from one end of the serving tube with an aiming ring, pull the pull rope, the wrapping sheet, and the elastic rope to stretch and deform the elastic rope, and launch the volleyball by relying on the elastic force of the elastic rope. The launching force cannot be accurately controlled. For example, the patent with publication number CN215136729U discloses an automatic volleyball serving machine, including a launching block, a ball feeding mechanism, an ejection mechanism, a support seat and an angle adjustment mechanism; a serving groove arranged along the length direction of the launching block is opened on the right side wall of the launching block, and the ball feeding mechanism is provided. The mechanism is arranged on the top of the launching block, and is used for intermittently supplying the volleyball into the serving groove; the ejection mechanism is arranged in the serving groove, and is used for ejecting the volleyball in the serving groove; the support seat is arranged below the launching block. After the volleyball falls into the serving groove, the volleyball itself has strong flexibility and is easy to eject from the serving groove, and during the launching process, it will move with the hitting board.

When the volleyballs are stored, they are stored through the spiral goal channel 321. The spiral goal channel 321 is spirally arranged in the ball storage box 32, which can not only increase the length of the spiral goal channel 321 and improve the storage capacity of the volleyballs, but also avoid the volleyballs from being directly stacked up and down, causing the volleyballs to squeeze each other, which may block the volleyballs in the goal channel. When the volleyball scores a goal in the spiral goal channel 321, it mainly rolls and falls by its own gravity, and at the same time, a part of the force is borne on the side wall of the spiral goal channel 321, which avoids excessive squeezing between the volleyballs and facilitates the smooth scoring of the volleyball. The electric gate can select an appropriate model on the market according to the needs. The electric gate can be set at the end of the spiral goal channel 321. Only one ball is scored each time. After the volleyball enters the hitting channel 311, due to the limitation of the launch angle, the hitting channel 311 is tilted, and the volleyball rolls into the launcher 2 by its own gravity and is transported to the designated position by the conveying member 8. Specifically, the base 1 includes a flatbed trolley 11, a lifting seat 12, a guide rod 4 13, a limit plate 14 and a cylinder 3 15.
