[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Please see Figure 1-5 As shown, this utility model is a tennis ball loading mechanism.

[0026] When tennis balls are launched by a ball-serving machine for athletes to practice hitting the ball, the ball-serving machine 3 is installed behind the screen 1 with the launching port. After the athlete hits the ball, the ball slides down the screen 1 into the ball-receiving groove 2 placed below the screen 1, and is then transported to the ball-serving machine by the ball-loading device 4.

[0027] The ball feeder 4 lifts and transports the tennis ball, which is in a low position and located in the ball receiving groove 2, to the ball feeder 3 installed on the bracket 1. The ball feeder 3 is in a high position, which makes it convenient for the ball feeder 3 to send out high ball trajectories, thus simulating the real smash that is convenient for athletes.

[0028] Specifically, the upper end of the ball frame 404 has an outer edge, a portion of which extends to form a ball receiving plate 401. This extension is located near the curtain of the ball frame 404. The ball receiving plate 401 rests on the ball outlet of the ball receiving groove 2. A sensor 402 is provided at the junction of the tail end of the ball receiving plate 401 and the frame of the ball frame 404. The sensor 402 is used to detect whether there is a ball that can enter the ball frame 404, so that the ball can be fed by the horizontal toothing device 4010.

[0029] The bottom center of the ball frame 404 is recessed inward to form a motor base 4011. The top of the motor base 4011 has a hole. The ball frame 404 has a ball exit channel 403, which is located at the bottom between the frame wall of the ball frame 404 and the motor base 401. The radial cross-section of the ball exit channel 403 is arc-shaped. The frame wall at the outlet of the ball exit channel 403 has a stop, which allows the ball exit channel 403 to exit the ball in one direction. In addition, a bearing 4014 is installed at the ball exit hole of the ball frame 404 to prevent the ball from getting stuck.

[0030] The horizontal tooth-picking device 4010 includes tooth 409 and a top cap 407. A motor 4012 is installed in the motor base 4011. The motor drives the horizontal tooth-picking device 4010 to rotate. The drive shaft of the motor 4012 extends into the ball frame 404. The top cap 407 is provided on the drive shaft of the motor 4012. A ring of tooth 409 is provided on the circumferential surface of the top cap 407. The top cap 407 and the ring of tooth 409 are integrated. Adjacent tooth 409s form an arc-shaped ball-picking groove. The ball-picking groove is located above the ball exit channel 403. After the tennis ball enters the ball frame 404, it falls into the arc-shaped ball-picking groove. The ball is held by the ball-picking groove. Then, the rotation of the horizontal tooth-picking device 4010 pushes the ball along the ball exit direction of the ball exit channel 403. The ball exit speed of the ball machine can be controlled by the rotation speed of the motor 4012.

[0031] Preferably, the end of the tooth 409 is provided with a small bearing 408, which can prevent friction and compression with the ball during the process of the horizontal tooth-picking device 4010 picking the ball.

[0032] Furthermore, it also includes a lifting pipe 406, a ball outlet hole on the side of the ball frame 404, one end of the lifting pipe 406 is connected to the ball outlet hole of the ball frame 404 through a flange 405, the ball outlet end of the ball outlet channel 403 is connected to the ball outlet hole, and the other end of the lifting pipe 406 is connected to the ball inlet at the bottom of the ball launcher 3 through a flange 405.

[0033] Furthermore, a base 4013 is provided at the bottom of the ball frame 404, and bolt fixing holes are provided on the plate of the base 4013.
