Description

Technical Field

[0001] This utility model relates to the field of volleyball training technology, and in particular to a volleyball serving machine that is easy to move. Background Technology

[0002] Volleyball is a recreational sport with moderate exercise intensity and fun. Receiving the ball is one of the basic skills in volleyball training. However, relying on the training partner to serve the ball manually is not only inefficient and ineffective, but also leads to fatigue for the training partner. Therefore, ball-serving machines are now commonly used to achieve automatic ball serving in volleyball.

[0003] Existing patents, such as the one with authorization announcement number CN218357256U, disclose an automatic volleyball serving machine. This machine vertically places volleyballs one by one into a ball-holding box, enabling intermittent serving and saving energy by avoiding repeated ball retrieval. The diameter of the volleyball is smaller than the diameter of the ball-dispensing groove, and it slides from the groove into a sliding channel. In conjunction with a rotating device, when the ball slides between the second friction wheel and the first friction wheel, the second driver drives the second friction wheel to rotate using the principle of wheel friction. The first friction wheel gains kinetic energy under the rotational friction of the second friction wheel, thus launching the volleyball. This facilitates receiving training, and because it is an automatic serving machine, the serving efficiency is not reduced, thereby improving the training effect. However, in actual use, the ball-serving machine has a limited internal space in the ball-collecting box, which limits the number of volleyballs it can hold. Therefore, when the volleyballs are all served, the training partner needs to run back and forth to load the volleyballs stored in the external ball collector into the ball-collecting box. This can lead to fatigue for the training partner and affect the efficiency of volleyball serving, which is not conducive to the training of volleyball receiving and thus affects the training effect. Utility Model Content

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-6 The mobile volleyball serving machine shown includes a mobile frame 1 and a serving assembly mounted on the mobile frame 1. The mobile frame 1 is also equipped with a ball collecting component. The top of the mobile frame 1 is equipped with universal self-locking wheels to facilitate the movement and fixation of the serving machine.

[0027] The ball collecting component includes a ball collecting box 2 installed on the top of the movable frame 1. The ball collecting box 2 has a first partition 16 and a second partition 18 arranged in a T-shape. The front side of the ball collecting box 2 is hinged with a box door 11. The first partition 16 and the second partition 18 divide the interior of the ball collecting box 2 into an installation cavity and two ball collecting cavities. Each of the two ball collecting cavities is provided with two ball collecting racks 17 arranged vertically. The tops of the four ball collecting racks 17 are recessed inward to form ball collecting grooves. Each of the four ball collecting racks 17 has a slot that communicates with the ball collecting groove on one side. The four ball collecting racks 17 are also detachably provided with a blocking member to seal the slot. The installation cavity is provided with four pushing members, and the four pushing members drive the four ball collecting racks 17 to move horizontally.

[0028] Specifically, each pusher includes an electric push rod 20 fixed on the side of the second partition 18 away from the first partition 16, and a connecting block 21 installed at the bottom of the ball collecting frame 17. The telescopic end of the electric push rod 20 extends into the ball collecting cavity after passing through the second partition 18 and is fixedly connected to one side of the connecting block 21. The inner wall of the ball collecting box 2 and both sides of the first partition 16 are equipped with slide rails, and both sides of the ball collecting frame 17 are provided with slide grooves that cooperate with the slide rails.

[0029] Specifically, the shielding component includes a pull plate 25, a baffle 19 matching the ball collecting groove is installed at the bottom of the pull plate 25, and a plug rod 23 is installed at the bottom end of the baffle 19. The ball collecting frame 17 has a plug hole 22 for the plug rod 23 to be inserted, and a positioning block 24 is installed at the top of the ball collecting frame 17. The bottom of the pull plate 25 also has a positioning groove that cooperates with the positioning block 24.

[0030] Specifically, the serving assembly includes a ball storage cylinder 3 and a serving rack 5 installed at the bottom of the ball storage cylinder 3. The ball storage cylinder 3 has a ball storage cavity 4 in the middle, and a ball outlet 6 communicating with the ball storage cavity 4 is also opened at the bottom of the ball storage cylinder 3. The serving rack 5 has a serving channel 8 that cooperates with the ball outlet 6 at the top, and auxiliary wheels 7 and serving wheels 9 are symmetrically distributed on both sides of the serving channel 8 and rotatably installed at the top of the serving rack 5. A through cavity is opened on one side of the serving rack 5, and a first motor 10 that drives the serving wheel 9 to rotate is installed in the through cavity. The ball collection box 2 is located below the ball storage cylinder 3 and the serving rack 5.

[0031] As described above, during volleyball receiving training, the ball-serving machine can be moved to the training location via the movable frame 1, and then the volleyballs can be placed into the ball storage chamber 4 in sequence. The volleyball at the bottom rolls down through the ball outlet 6 into the ball-serving channel 8 on the ball-serving frame 5. Then, the first motor 10 drives the ball-serving wheel 9 to rotate, so that the volleyballs are served along the ball-serving channel 8 with the cooperation of the ball-serving wheel 9 and the auxiliary wheel 7. This process is repeated to achieve the sequential serving of the volleyballs in the ball storage chamber 4 for trainees to practice volleyball receiving.

[0032] After training, the box door 11 can be opened, and the connecting block 21 can be pushed by the telescopic ends of the four electric push rods 20. This causes the connecting block 21 to move the ball collecting rack 17 along the ball collecting box 2 in cooperation with the slide rail and slide groove, so that the four ball collecting racks 17 can be moved out of the ball collecting box 2. Then, the trainee places the volleyballs into the ball collecting grooves on the four ball collecting racks 17 in sequence, and inserts the baffle 19 into the ball collecting groove by pulling plate 25, so that the insertion rod 23 is inserted into the insertion hole 22, and the positioning block 24 is inserted into the positioning groove, so as to realize the insertion and fixation of the baffle 19. Then, the baffle 19 is used to limit the volleyballs in the ball collecting groove, preventing the volleyballs from rolling out of the ball collecting groove. The ball receiving rack 17 is moved into the ball receiving box 2 by the electric push rod 20, and the box door 11 is closed, which facilitates the orderly storage of volleyballs. In subsequent training, the box door 11 is opened, the ball receiving rack 17 is pushed out of the ball receiving box 2 by the electric push rod 20, and then the volleyballs stored on the ball receiving rack 17 are put into the ball storage cavity 4 to serve. Thus, the ball serving machine integrates serving and ball receiving, avoiding the problem of training partners having to run back and forth to take out the volleyballs from the external ball collector and put them into the ball storage cavity 4. This not only reduces the labor intensity of training partners, but also greatly facilitates volleyball receiving training for trainees, which is conducive to improving training efficiency.

[0033] Furthermore, to facilitate maintenance of the pushing components within the mounting cavity, such as... Figures 3-5 As shown, the ball collecting box 2 is also hinged to an inspection door 15 on the side away from the box door 11.

[0034] Additionally, in this embodiment, as Figures 1-3 As shown, the movable frame 1 is also equipped with a height adjustment mechanism for driving the ball-serving assembly to rise and fall. The height adjustment mechanism includes a support frame 12 installed on the top of the movable frame 1. A through groove is opened in the middle of the support frame 12, and a lead screw 14 is rotatably installed in the through groove. A second motor 13 for driving the lead screw 14 to rotate is fixed at the top of the support frame 12. A lead screw seat that can move up and down along the through groove is connected to the lead screw 14, and one side of the lead screw seat is fixedly connected to the side of the ball storage cylinder 3 away from the ball-serving frame 5.

[0035] During the serve, the second motor 13 drives the lead screw 14 to rotate. At this time, the lead screw 14 drives the lead screw seat to move along the through groove. Then, the lead screw seat drives the ball storage cylinder 3 to rise and fall along one side of the support frame 12, thereby adjusting the height of the ball storage cylinder 3 and the serving frame 5. This allows the height of the volleyball served by the serving frame 5 to meet the needs of trainees of different heights, thus facilitating volleyball training for trainees of different heights and greatly improving the practicality of the serving machine.

[0036] Furthermore, to ensure the screw seat moves stably along the through groove under the drive of the screw 14, such as... Figures 1-3 As shown, limit strips are installed on both sides of the inner wall of the through groove, and limit grooves that cooperate with the limit strips are opened on both sides of the screw seat.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
