[0040] Below we explain the specific structure of the cricket serve recovery integrated trainer:

[0041] The serving power module includes a power motor, a pinion, a large gear, a reel, a spring and a bayonet. The power motor is installed in the special groove of the power motor of the bottom shell. The pinion is installed on the power motor shaft and can rotate in coordination with the power motor shaft. The large gear meshes with the pinion and is installed on the upper part of the reel. It is coaxial with the reel and can rotate with the reel. The reel and the large gear are installed on the center column between the bottom shell and the middle cover through their center holes. The spring is located inside the launch tube, and its lower end is welded to the flat plate inside the launch tube, and the upper end is welded to the bayonet. The bayonet is located inside the launch tube and can move up and down along the inner wall of the launch tube. Working principle: the cricket ball is connected to the incoming line through a net bag. When the cricket ball is located on the bayonet, the power motor is powered on and rotated, and the pinion and large gear drive the reel to rotate and reel the line. The reel presses the bayonet downward, and the bayonet is pressed downward to compress the spring. When the spring is compressed to a certain extent, the motor is powered off and the ball is ejected by the spring.

[0042] The launch angle adjustment module includes a rotating motor, a worm, a rotating rod and a launch tube. The rotating motor is installed in a special groove for the rotating motor of the bottom shell. One end of the worm is installed on the rotating shaft of the rotating motor, and the other end is installed on the special groove for the worm of the bottom shell. The worm is meshed with the gear structure of the rotating rod. The rotating rod is fixed between the middle cover and the top cover through a circular hole axis formed by two semicircular grooves of the middle cover and the top cover. One end of the rotating rod is a gear structure that meshes with the worm, and the other end is a groove-shaped plane. The two circular holes on the plane are aligned with the two circular holes on the launch tube and fixed by screws and nuts. The working principle of this module is: when the launch angle is to be adjusted, the control circuit can be used to control the rotating motor and the forward and reverse rotation. The rotation of the motor drives the worm to rotate, and the rotation of the worm drives the rotating rod gear structure to rotate, so that the wheel rod rotates, and then drives the launch tube to rotate. Since the rod length ratio of the two ends of the lever formed by the worm and the rotating gear is relatively large, it is easy to rotate from the worm end and difficult to rotate from the rotating rod end, so that the launch angle of the launch tube is self-locking after the rotating motor stops.

[0043] The recovery module includes a wire wheel and a spiral spring. The wire wheel is installed on the center column between the bottom shell and the middle cover through its center hole, and the spiral spring is located inside the wire wheel, with its inner end fixed on the center column through the groove of the center column, and its outer end hooked on the special hook of the spiral spring in the inner circle of the wire wheel through a hook-like structure.

[0044] The working principle of this module is as follows: when the cricket ball is hit, the reel is driven by the ball to release the line and rotate, and the scroll spring inside it shrinks due to the rotation, generating a torque in the opposite direction. This torque cushions the ball during flight, and after the ball stops, it drives the reel to rotate in the opposite direction to reel in the line, thereby retrieving the ball.

[0045] The control module includes a controller and a pressure sensor. The pressure sensor is located between the flat plate and the spring inside the launch tube. Working principle: The controller receives the pressure data of the spring on the flat plate collected by the pressure sensor and converts it into an electrical signal to control the opening and closing of the power motor.

[0046] The working process of the cricket serve and recovery integrated trainer is as follows:

[0047] (1) A switch is provided on the outer surface of the device. When the switch is turned on, the ball server is powered on.

[0048] (2) The ball server has two serving modes: single serving mode and multiple serving mode. You can select the serving mode by the remote control.

[0049] (3) Press the single serve switch to start the single serve mode, which consists of two processes: serving and receiving.

[0050] (a) Serving process: Press the switch, and the motor drives the reel to rotate (the rope is wrapped around the reel, and the two ends are fixed to the reel and the cricket ball respectively). Therefore, when the motor rotates, the cricket ball moves into the tube. During this process, the spring in the tube is continuously compressed. When the spring is compressed to a certain extent, the pressure sensor outputs a signal, the motor is powered off, and the spring ejects the cricket ball.

[0051] (b) Ball collecting process: After the cricket ball is ejected, the cricket ball will drive the spool to rotate and thus retract the scaffolding spring because there is a scaffolding spring inside the spool and the scaffolding spring is fixed to the spool. The scaffolding spring generates a reverse torque, causing the cricket ball to be continuously pulled by the rope during the ejection process and eventually be pulled back into the serving tube.

[0052] (The ball collection process is powered by the spiral spring inside the serving machine's reel, and the power supply is no longer supplied. If you need to serve again, you need to operate the remote control to select the mode again.

[0053] (4) Press the multiple serve switch to start the multiple serve mode. The serving and receiving process is the same as the single serve. However, after the ball returns to the serving tube, when the pressure sensed by the pressure sensor reaches a predetermined value, the serving process will be started again and the cycle will continue. If you want to stop serving, just press the remote control to turn it off.

[0054] (5) After use, you need to turn off the switch on the outer surface of the server.

[0055] The present invention utilizes the spring principle and the kinetic energy theorem and fully utilizes the kinetic energy of the engine, thereby solving the problem that the traditional serving machine has low kinetic energy and cannot effectively hit the cricket ball; the cricket ball is innovatively recovered by utilizing the scroll spring elastic line recovery principle, thereby quickly recovering the cricket ball and solving the problem of difficulty in recovering the cricket ball; the single serving and multiple serving modes are adopted to specifically improve the hit rate and proficiency of hitting the ball.
