Description

Technical Field

[0001] The utility model relates to the technical field of sports training equipment, in particular to a youth training football ball-serving machine capable of outputting at multiple speeds. Background Art

[0002] Ball machines are widely used in sports training, especially ball sports training. When using a ball machine, it needs to be carried to the court and put away after training. Therefore, whether the ball machine can be carried easily determines the user experience of the ball machine to a large extent.

[0003] The existing ball serving machine has universal wheels at the bottom, which can be dragged directly. However, due to the reaction force generated when serving the ball, the ball serving machine itself will be displaced.

[0004] In addition, adjustable serving speed is a common function of existing ball serving machines, which can be achieved by adjusting the rotation speed of the rubber roller. However, most ball serving machines do not have the function of adjusting the serving frequency during continuous serving. The continuous serving frequency can only be determined by the speed at which the ball naturally rolls to the rubber roller. Utility Model Content

[0005] The purpose of the present utility model is to provide a youth training football ball serving machine with multi-speed output in order to solve the above problems, as described below.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0033] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 4 As shown, the utility model provides a youth training soccer ball serving machine capable of multiple gears and constant speed output, comprising a trolley 1, on which two second servo motors 11 are provided, and a rubber roller 13 is fixed to the output shaft of the second servo motor 11, and a guide rail 14 is obliquely provided on the trolley 1, and the guide rail 14 is located between the two rubber rollers 13;

[0035] The trolley 1 is provided with an adjustment seat 10 for supporting the trolley 1 and adjusting the direction and inclination of the guide rail 14;

[0036] The trolley 1 is provided with a ball storage bucket 2 capable of storing a plurality of balls, and the lower end of the ball storage bucket 2 corresponds to the guide rail 14. The ball storage bucket 2 is provided with a speed regulating component 3 for regulating the speed at which the balls fall from the ball storage bucket 2. The ball storage bucket 2 is made of plastic, the purpose of which is to reduce the weight of the ball storage bucket 2.

[0037] As an optional embodiment, the ball storage bucket 2 includes a conical bucket 6, and a pipe 7 is provided at the bottom of the conical bucket 6, and the lower end of the pipe 7 corresponds to the guide rail 14;

[0038] The same height inside the pipe 7 can only accommodate one ball, and the ball storage hopper 2 is provided to store multiple balls at the same time, so that the device can serve balls continuously and reduce the number of times of filling balls.

[0039] A fixing sleeve 4 is fixed on the conical bucket 6, and the fixing sleeve 4 is mounted on the push handle of the trolley 1, and a handle 5 is fixed on the fixing sleeve 4;

[0040] The main reason affecting the portability of the ball serving machine is the ball bin or ball bucket used to store balls. Most existing ball serving machines are fixed with a ball bin. The advantage of the ball bin is that it can be filled with balls once and serve several times continuously, which is more suitable for one person to train. However, the ball bin is large in size, which affects the portability of the ball serving machine.

[0041] If multiple people are training and there is a special ball basket for placing balls, teammates can put balls into the ball machine specifically, so there is no need for the ball bin that comes with the ball machine. However, the ball bin that comes with the existing ball machine is difficult to install and remove, resulting in users being unable to choose whether to use the ball bin. Even if they do not use it, they still need to carry it with them, which inconveniences the users.

[0042] The ball storage bucket 2 is mounted on the trolley 1 through the fixing sleeve 4. This installation method is quick and convenient for disassembly.

[0043] The speed regulation component 3 includes a first servo motor 8, which is fixed on the pipe 7, and a cross 9 is fixed on the output shaft of the first servo motor 8. A through-bar groove is provided on the pipe 7, and the cross 9 passes through the bar groove into the inside of the pipe 7. The cross 9 can prevent the ball in the pipe 7 from rolling downward. Every time the first servo motor 8 drives the cross 9 to rotate ninety degrees, a ball can be released downward. By setting the speed at which the first servo motor 8 rotates the cross 9, the speed at which the ball falls to the guide rail 14 can be controlled, thereby adjusting the frequency of continuous serving of the ball machine.

[0044] The trolley 1 is provided with a protective cover 12 for covering the two rubber rollers 13 .

[0045] A control box 15 is provided on the protective cover 12. The control box 15 is electrically connected to the first servo motor 8 and the two second servo motors 11. The control box 15 can make the two second servo motors 11 rotate synchronously or at different speeds.

[0046] The control box 15 can adjust the rotational speed of the two second servo motors 11. The higher the rotational speed, the higher the serving speed. The control box 15 can create a rotational speed difference between the two second servo motors 11, and then a curve ball can be launched. The control box 15 and the second servo motors 11 are both existing technologies, and their principles will not be repeated here.

[0047] The adjustment seat 10 includes a support plate 16, on which a fixed shaft 17 is rotatably provided, and the fixed shaft 17 is fixed to the trolley 1, and screws 20 are vertically threaded at the four corners of the support plate 16, and a rotating disk 21 is fixed on the screw 20, and the lower end of the screw 20 is hemispherical. The hemispherical design can reduce the resistance of the screw 20 to the ground when the screw 20 is rotated. The screw 20 is rotated by the rotating disk 21, and the height of the four screws 20 passing through the bottom of the support plate 16 is adjusted separately, so that a height difference is generated at the lower ends of the screws 20 on both sides, and the posture of the trolley 1 can be tilted.

[0048] A threaded sleeve 19 is fixed on the support plate 16, and a bolt 18 is connected to the inner thread of the threaded sleeve 19, and the end of the bolt 18 corresponds to the surface of the fixed shaft 17. The bolt 18 is rotated so that the end of the bolt 18 supports the fixed shaft 17, thereby fixing the fixed shaft 17 to prevent the trolley 1 from rotating again after the direction adjustment is completed.

[0049] With the above structure, the device is easy to move and thus easy to carry by providing a trolley 1, and the ball storage hopper 2 is provided so that the ball serving machine can serve balls continuously. The speed of the balls falling from the ball storage hopper 2 to the guide rail 14 can be controlled by providing a speed regulating component 3, thereby adjusting the frequency of continuous serving.

[0050] The ball can contact the two rubber rollers 13 along the guide rail 14. The rotation speeds of the two rubber rollers 13 are opposite. The ball can be ejected through the cooperation of the two rubber rollers 13. If there is a speed difference between the two rubber rollers 13, an arc-shaped ball can be ejected.

[0051] If continuous serving is not required, the ball storage hopper 2 can be directly removed from the trolley 1, thereby further improving the portability of the ball serving machine;

[0052] The direction and up and down tilt angle of the trolley 1 can be adjusted by adjusting the seat 10, so that the trajectory of the ball can be changed. When the adjusting seat 10 contacts the ground, the wheels of the trolley 1 can be separated from the ground, thereby improving the stability of the ball machine when serving.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
