Figure 2 As shown, the left push plate 15, the right push plate 16, the main push plate 17 and the electric control baffle 18 are used to limit the volleyball to be thrown.

[0050] In this embodiment, it should be noted that the center positions of the left and right ball pushers 14 corresponding to the left pusher plate 15, the right pusher plate 16 and the main pusher plate 17, as well as the center positions of the upper and lower ball pushers 11 are all provided with limiting grooves adapted for the volleyball to be thrown.

[0051] In this embodiment, it should be noted that: when the volleyball to be thrown is limited in the limiting grooves corresponding to the upper and lower ball pushers 11, the volleyball to be thrown is also fully fit-fitted and limited in the limiting grooves corresponding to the left push plate 15, the right push plate 16 and the main push plate 17.

[0052] In this embodiment, it should be noted that: the upper and lower ball pushers 11 are used to push the volleyball to be thrown upward; the left and right ball pushers 14 corresponding to the left push plate 15 are used to push the volleyball to be thrown to the left; the left and right ball pushers 14 corresponding to the right push plate 16 are used to push the volleyball to be thrown to the right; the main push plate 17 is used to push the volleyball to be thrown forward.

[0053] In this embodiment, it should be noted that: based on the preset electric control door control conditions, the controller and the detection identifier 13 adjust the opening and closing of the first electric control door 8 and the second electric control door 9;

[0054] The preset electric door control conditions are:

[0055] When the detection identifier 13 does not detect that there is a volleyball to be thrown on the upper and lower ball pushers 11, the controller opens the second electric control door 9. When the volleyball to be thrown between the first electric control door 8 and the second electric control door 9 falls into the ball thrower 3, the second electric control door 9 is closed.

[0056] When the detection identifier 13 detects that the volleyball to be thrown falls into the ball thrower 3, the controller opens the first electric control door 8. When the volleyball to be thrown located in the ball outlet channel 6 falls between the first electric control door 8 and the second electric control door 9, the first electric control door 8 is closed.

[0057] The automatic ball throwing machine for volleyball training described in the first embodiment is provided with multiple sets of one-to-one corresponding storage chambers, ball outlet channels and ball outlets, and is provided with: a ball thrower corresponding to the ball outlet one-to-one, thereby enabling: launching multiple volleyballs at a time; at the same time, the controller is electrically connected to the first and second electric-controlled doors, the ball thrower, and the external display device. Based on the preset electric-controlled door control conditions, the switches of the first and second electric-controlled doors are adjusted by the controller and the detection identifier to ensure that the volleyball in the storage chamber continuously falls into the ball thrower automatically and accurately based on the ball outlet along the ball outlet channel having a certain slope and provided with a limiting groove; and based on the ball throwing information preset on the external display device, the upper and lower ball pushers and the left and right ball pushers provided on the ball thrower are used to control the throwing force, throwing direction and throwing height of the volleyball;

[0058] For the automatic ball throwing machine for volleyball training described in the aforementioned embodiment 1, a plurality of movable rollers are provided at the bottom of the base to facilitate the movement of the automatic ball throwing machine; a fixed support assembly electrically connected to the controller is embedded in the bottom of the base, and the fixed support assembly includes: a fixed support plate and a plurality of telescopic support rods, which can then control the extension and retraction of the telescopic support rods so that the fixed support plate can fix the automatic ball throwing machine at a preset serving position. Example

[0059] This embodiment provides a method for using the automatic ball throwing machine described in the first embodiment, and the method specifically includes:

[0060] The initial state of the automatic ball throwing machine is as follows Figure 1 As shown, Figure 1 The automatic ball throwing machine shown in the figure moves to the preset serving point; by pressing the control button of the external display device 4, the extension and contraction of the multiple telescopic support rods 21 are synchronously adjusted, so that the fixed support plate 20 fixedly connected to the multiple telescopic support rods 21 is lowered, so as to achieve: the entire structure of the automatic ball throwing machine is lifted up until the multiple moving rollers 19 leave the bottom surface. The state of the automatic ball throwing machine after completing the above operation is as shown in FIG. Figure 2 shown.

[0061] After the automatic ball-throwing machine is fixed to the preset serving point, the volleyballs to be thrown are evenly placed in different storage compartments 5. It should be noted that the corresponding size of the standard competition volleyball is fixed, and because the width of the storage compartment 5 is 1.25 times the diameter of the volleyball to be thrown, the volleyballs inside the storage compartment 5 are automatically stacked in layers during the volleyball release process, and the volleyballs will not be difficult to remove due to the volleyballs being piled up and messy. It should be noted that when the volleyballs are released, the first electric-controlled door 8 is initially open, and the second electric-controlled door 9 is initially closed. Because the slope of the ball outlet channel 6 decreases from front to back, the volleyballs will fully occupy the space enclosed by the second electric-controlled door 9.

[0062] After all the volleyballs have been thrown, the user can set the preset number of balls to be thrown, the preset interval between balls to be thrown, the preset direction of balls to be thrown, and the force of balls to be thrown by pressing the control button of the external display device 4. Furthermore, the user can close the first electric control door 8 by pressing the control button of the external display device 4. Since the distance between the first electric control door 8 and the second electric control door 9 is 1.25 times the diameter of the volleyball to be thrown, a volleyball is ensured to be stored between the first electric control door 8 and the second electric control door 9. After completing the above operations, the automatic ball throwing machine can start the ball throwing operation by pressing the control button of the external display device 4.

[0063] The process of the ball throwing operation of the automatic ball throwing machine is as follows:

[0064] When the detection identifier 13 does not detect that there is a volleyball to be thrown on the upper and lower ball pushers 11, the controller automatically opens the second electric control door 9, and the volleyball originally stored between the first electric control door 8 and the second electric control door 9 falls accurately into the ball thrower 3 based on the limiting groove 22 provided at the front end of the ball outlet channel 6, and then the controller automatically closes the second electric control door 9; when the detection identifier 13 detects that the volleyball to be thrown falls into the ball thrower 3, the controller automatically opens the first electric control door 8, causing the volleyball to be thrown located in the ball outlet channel 6 to fall between the first electric control door 8 and the second electric control door 9, and then the controller automatically closes the first electric control door 8; based on the above operation, it is ensured that there is a volleyball stored continuously between the first electric control door 8 and the second electric control door 9, thereby ensuring that there is a volleyball continuously falling into the ball thrower 3 for the corresponding ball throwing operation;

[0065] The structure formed by the left push plate 15, the right push plate 16, the main push plate 17 and the electric control baffle 18 limits the position of the volleyball falling into the ball thrower 3; then, based on the left push plate 15, the right push plate 16 and the main push plate 17 corresponding to the left and right ball pushers 14, and the upper and lower ball pushers 11 provided on the bottom plate 12, the volleyball falling into the ball thrower 3 is thrown according to the preset ball throwing information; it should be noted that; when throwing the ball, in order to reduce the influence of the electric control baffle 18 on the throwing operation, the controller controls the electric control baffle 18 to fold outward based on the shaft structure. When the current ball throwing is completed, the electric control baffle 18 folds inward based on the shaft structure to restore to its original state, so as to play the role of limiting the volleyball again;

[0066] Because the push plate assembly comprises a connection and fixing structure in which the left and right push plates 15, 16 symmetrically clamp the main push plate 17, and the push plates 15, 16 are arranged inwardly relative to the main push plate 17, the height of the ball can be controlled by controlling the pushing force of the upper and lower ball pushers 11, and the distance and direction of the ball can be controlled by controlling the pushing force of the left and right ball pushers 14 corresponding to the left and right push plates 15, 16, and main push plate 17. Specifically, the optional throwing directions include: straight ahead, slightly left of the front, and slightly right of the front.

[0067] After completing the ball throwing operation, by pressing the control button of the external display device 4, the extension and retraction of the multiple telescopic support rods 21 are synchronously adjusted, causing the fixed support plate 20 fixedly connected to the multiple telescopic support rods 21 to rise, so as to achieve: causing the overall structure of the automatic ball throwing machine to descend until all the moving rollers 19 fall to the bottom, and then the automatic ball throwing machine can be moved to the corresponding position.
