Problems solved by technology

[0002] In the process of table tennis training, most of the balls are artificially served to the students to hit, but this method will take up a lot of manpower, and it is impossible to train at any time, so the ball machine has gradually become the main equipment for training. The current ball machine mainly It is a fixed way of serving, which cannot train students' adaptability, thereby reducing the quality of training, and the current ball machine cannot recover the returned table tennis balls, so trainers need to frequently add table tennis balls to the ball machine , wasting the trainer's precious time

Embodiment 1

[0028] Please refer to the accompanying drawings, the present invention provides a technical solution: a table tennis ball serving device, including a base plate 1, a column 2 is welded on the top of the base plate 1, a box 3 is fixedly installed on the top of the column 2, and the inner cavity of the box body 3 The top is fixed with a guide rail 4, the inner wall of the guide rail 4 is rotatably connected with a screw rod 5, the back of the guide rail 4 is fixedly installed with a first motor 6, the output shaft of the first motor 6 is fixedly installed with the screw rod 5, and the surface of the screw rod 5 is threaded Be connected with movable block 7, the bottom of movable block 7 is fixedly equipped with slide block 8, and the left side of slide block 8 is fixedly installed with air jet pipe 9, and the surface of air jet pipe 9 is fixedly installed with electromagnetic valve 35, and the left end of air jet pipe 9 communicates with Place the tube 10, the left end of the tu...

Embodiment 2

[0036]The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that a bracket 26 is welded on the top of the placement tube 10, the other end of the bracket 26 penetrates to the outside of the box body 3, and the serving tube 12 is rotatably connected to the inside of the bracket 26 , the front of the bracket 26 is threadedly connected with a lock wire 27, and the other end of the lock wire 27 is attached to the serving tube 12. Through the setting of the bracket 26, the serving angle of the serving tube 12 can be adjusted conveniently to meet different usage requirements. And the adjusted serving tube 12 can be locked by the locking wire 27 .

Embodiment 3

[0038] The structure of this embodiment is basically the same as that of Embodiment 1, the difference being that a frame 28 is arranged above the hollow disk 17, and a crossbeam 29 is welded inside the frame 28, and the bottom of the crossbeam 29 is fixedly installed with the hollow disk 17, and the frame 28 The bottom is fixedly equipped with a net pocket 30, and the net pocket 30 is covered outside the casing 3. The bottom of the net pocket 30 is fixedly equipped with a collection bucket 31, and the bottom of the suction pipe 24 extends to the inside of the collection bucket 31. The left side of the collection bucket 31 is connected to the column 2. Fixed installation, the device is equipped with a net bag 30, its purpose is to be able to pass the block of the net bag 30 after the student hits the ball back, so that the ball falls into the collection bucket 31 below the net bag 30, thereby avoiding the accident of picking up the ball. It saves a lot of time for students and e...
