Description

Technical Field

[0001] This utility model belongs to the technical field of tennis sports equipment, specifically relating to an automatic tennis ball collecting device. Background Technology

[0002] Tennis training often involves multi-ball drills, such as continuous serve practice and continuous forehand or backhand shot practice. Multi-ball drills typically involve one or more baskets of tennis balls for practice. However, even with a large number of balls, after the initial practice session, the player must pause to spend a considerable amount of time collecting the scattered balls back into the basket for the next round. Because of the large number of scattered tennis balls and their wide distribution across the tennis court, collecting them is a time-consuming and laborious task for the player.

[0003] Chinese patents CN102145223B and CN213724727U disclose an automatic tennis ball launcher and receiver, respectively. Both solutions address tennis ball collection, eliminating the need for manual ball retrieval, but still require manual pushing to various scattered locations, which is time-consuming and labor-intensive. Additionally, some ball-serving machines on the market have retrieval functions, but their large size often prevents the collection of many balls, leading to a rapid depletion of balls in the serving system and interrupting training sessions.

[0004] Therefore, there is an urgent need to propose an automatic tennis ball collecting device that can continuously receive and send balls. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic tennis ball collecting device.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model provides an automatic tennis ball collecting device, comprising:

[0008] A ball-blocking device, located behind the ball-collecting device, is used to block the tennis ball and cause it to fall onto the ball-collecting device.

[0009] A ball collecting device includes a ball collecting base plate, a ball collecting left baffle, and a ball collecting right baffle. A ball collecting guide rail is provided on one side of the ball collecting base plate along its length. The ball collecting base plate is inclined from high to low in the direction away from the ball collecting guide rail and towards the ball collecting guide rail. The ball collecting left baffle and the ball collecting right baffle are respectively provided at both ends of the ball collecting base plate along its length. A ball screening channel is provided between the ball collecting left baffle or the ball collecting right baffle and the ball collecting guide rail.

[0010] The ball lifting device, located behind the ball blocking device and between the ball outlet of the ball screening channel and the ball basket of the ball serving machine, is used to transport the tennis balls in the ball collecting device into the ball basket of the ball serving machine.

[0011] Preferably, the ball-blocking device includes a hanger and a ball-blocking cloth, with the ball-blocking cloth suspended on the hanger.

[0012] Preferably, the ball-blocking cloth includes an elastic layer, a buffer layer, and a shock-absorbing layer arranged in sequence.

[0013] Preferably, the ball collecting base plate is inclined from high to low along its length.

[0014] Preferably, the ball collecting guide rail is horizontally arranged, and a power device for pushing tennis balls into the ball screening channel is provided on one side of the ball collecting guide rail.

[0015] Preferably, both the left and right ball collecting baffles include a vertical baffle and a horizontal baffle. The vertical baffles are located at both ends of the ball collecting base plate along its length, and the vertical baffles are located on the horizontal baffles. The ball screening channel is located above the ball collecting guide rail, and the two together form a ball screening channel.

[0016] Preferably, the ball lifting device includes a bracket, a motor, a ball lifting guide rail, a ball inlet channel, and a ball delivery channel. The ball lifting guide rail is installed on the bracket at an angle from high to low. The motor is installed on the bracket and its output shaft is connected to the ball lifting guide rail for transmission. The ball inlet of the ball inlet channel is connected to the ball outlet of the ball screening channel.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] This invention utilizes a ball-blocking device to intercept the ball. After interception, the ball stops flying and falls or bounces slightly before falling onto the ball-collecting device. Due to the inclined design of the ball-collecting base plate, the inclined or horizontal ball-collecting guide rail, and the power configuration, the ball falling onto the ball-collecting device can roll to the ball-lifting inlet under its own weight or additional power. Under the action of the motor, the ball is transported along the ball-lifting guide rail to the ball basket of the ball-serving machine, thus achieving continuous ball receiving and serving.

[0024] like Figures 1 to 2 As shown, this embodiment provides an automatic tennis ball collecting device, including a ball blocking device 1, a ball collecting device 2, and a ball lifting device 3.

[0025] In this embodiment, the ball-blocking device 1 is located behind the ball-collecting device 2 to block the tennis ball and cause it to fall onto the ball-collecting device 2. To achieve the best ball-blocking effect, the ball-blocking device includes a hanger and a ball-blocking cloth. The ball-blocking cloth is suspended on the hanger and includes an elastic layer, a buffer layer, and a shock-absorbing layer arranged sequentially. The elastic layer is composed of elastic fabric, the buffer layer is an air-filled layer with a thickness of <10cm, and the shock-absorbing layer is composed of non-elastic fabric. For slow balls, the elastic layer effectively blocks them; for fast balls, the elastic layer, buffer layer, and shock-absorbing layer work together to minimize the ball's rebound distance, and the size of the ball-collecting device perpendicular to the ball-blocking device is minimized.

[0026] In this embodiment, the ball collecting device 2 includes a ball collecting base plate 21, a left ball collecting baffle 22, and a right ball collecting baffle 23. A ball collecting guide rail 24 is provided on one side of the ball collecting base plate 21 along its length. The ball collecting base plate 21 is inclined from high to low from the direction away from the ball collecting guide rail 24 to the direction closer to the ball collecting guide rail 24. The ball collecting guide rail 24 is also inclined from high to low along its length. The left ball collecting baffle 22 and the right ball collecting baffle 23 are respectively located at both ends of the ball collecting base plate 21 along its length. A ball screening channel is provided between the left ball collecting baffle 22 or the right ball collecting baffle 23 and the ball collecting guide rail 24. Both the left ball collecting baffle 22 and the right ball collecting baffle 23 include a vertical baffle and a horizontal baffle. The vertical baffle is located at both ends of the ball collecting base plate along its length, and is positioned on top of the horizontal baffle. The ball screening channel is located above the ball collecting guide rail, and the two together form a ball screening channel. To achieve the best ball-collecting effect, a power unit can also be adapted, which may consist of a conveyor belt or compressed air, enabling the ball to move from one end of the ball-collecting device to the connection point with the ball-lifting device (i.e., roll to the ball inlet of the ball-lifting device).

[0027] In this embodiment, the ball lifting device 3 is located behind the ball blocking device and is positioned between the ball outlet of the ball sieving channel and the ball basket of the ball serving machine. It is used to transport tennis balls from the ball collecting device to the ball basket of the ball serving machine. The ball lifting device 3 includes a bracket 31, a motor 32, a ball lifting guide rail 33, a ball guiding channel 34, and a ball delivery channel 35. The ball lifting guide rail 33 is installed on the bracket 31 at an angle from high to low. The motor 32 is installed on the bracket 31, and its output shaft is connected to the ball lifting guide rail 33. The ball inlet of the ball guiding channel 34 is connected to the ball outlet of the ball sieving channel, and the ball outlet of the ball guiding channel 34 is connected to the lowest point of the ball lifting guide rail 33. The ball inlet of the ball delivery channel 35 is connected to the highest point of the ball lifting guide rail 33, and the ball outlet of the ball delivery channel 35 is connected to or located above the ball basket of the ball serving machine. The highest point of the ball collecting device is less than 40cm. In this embodiment, 40cm, 30cm, 20cm or 10cm can be selected. In order to make the ball collecting device as low as possible, the ball inlet of the ball lifting device is located at the bottom.

[0028] The following is a further explanation of this embodiment:

[0029] The ball-blocking device intercepts the ball, causing it to stop flying and fall or bounce slightly before landing on the ball-collecting device. Due to the inclined design of the collecting plate and guide rail, the ball, landing on the collecting device, rolls under its own weight to the ball-lifting inlet. Driven by a motor, the ball is transported along the lifting guide rail to the ball basket of the serving machine, thus enabling continuous serve and receive. Because the collecting device is extremely low, most tennis balls are hit above it, effectively preventing them from scattering onto the court.

[0030] In a preferred embodiment, the rest is the same as the previous embodiment, except that the ball collecting guide rail 24 is horizontally arranged, and a power device is provided on one side of the ball collecting guide rail 24 for pushing tennis balls into the ball screening channel. The power device pushes the tennis balls into the ball screening channel, thereby sequentially entering the ball inlet of the ball lifting device.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
