A. The function of the tennis ball machine
1. You can arbitrarily set and change different speeds, frequencies, directions, drop points, and spin for combined mode training.
2. The remote control can be paused to save power when picking up the ball, and the remote control can be placed in the pocket during training.
3. Built-in design of the direction control of the ball machine, it is difficult to judge the launch direction of the machine during training, and it also reflects the robotization.
4. The launching point of the ball machine: fixed point to half court or full court.
B. Tennis training machine: function training
Accurate practice: fixed point kick, draw shot, long draw, volley, touch the earth, forehand and backhand return, forehand and backhand three-line return, up and down spin, full court free kick, etc.
C. Operation principle of tennis ball shooting machine
The common tennis ball machines on the market can be divided into the following categories:
1. Two-wheeled ball machine: The roller-type ball machine uses wheels to serve the ball. As shown in the figure below, the space between the two wheels rotating at high speed and in opposite directions is slightly smaller than the diameter of the ball. When the ball rolls from the slide rail into the two wheels, the friction between the wheel and the ball will The ball spins out quickly.
2. Portable tennis ball machine: It is composed of a ball storage mechanism, a goal mechanism, an ejection mechanism, a frame and a control circuit, and is controlled by a single-chip microcomputer. Its working principle is to use the power source to compress the spring, and release the spring when the spring stores enough potential energy. The tennis ball obtains a certain initial energy in a certain position under the action of the spring potential energy, and then launches the ball. The operation of the portable ball machine is mainly based on the advantage that the spring can store larger potential energy.
3. Pneumatic ball machine: using the air pressure generated by the air compressor, it is stored in the gas collecting cylinder. When the ball falls into the ball pipe, the air in the cylinder is released and the ball is ejected under air pressure.
