Description

Technical Field

[0001] The utility model relates to sports equipment, in particular to a multi-directional and multi-angle tennis ball serving machine. Background Art

[0002] The tennis ball machine automatically launches tennis balls for trainers to practice with, freeing them from the tedious task of feeding balls to their coaches. With the tennis ball machine, trainers can practice hitting shots repeatedly and from multiple angles without the need for a coach, making it highly efficient.

[0003] Existing tennis ball machines, such as the adjustable tennis ball machine disclosed in the utility model patent with authorization announcement number CN221358450U, use fixed rigid pipes to transport tennis balls, which has poor flexibility and cannot meet the needs of multi-directional and multi-angle serving. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned problems and provide a multi-directional and multi-angle tennis ball serving machine. The ball serving machine adopts a soft pipe to transport tennis balls, has good flexibility, and can meet the needs of multi-directional and multi-angle serving.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A multi-directional and multi-angle tennis ball serving machine includes a ball storage box for storing tennis balls to be served, a hose for conveying tennis balls, a serving mechanism for serving tennis balls, and an adjustment mechanism for adjusting the posture of the serving mechanism.

[0007] The upper end of the hose is connected to the outlet of the ball storage box, and the lower end of the hose extends to the ball receiving end of the ball serving mechanism;

[0008] The serving mechanism includes a serving rack, a serving roller, and a roller driving mechanism for driving the serving roller to rotate. The serving roller is provided with two rollers and is connected to the serving rack so as to rotate relative to each other up and down.

[0009] The adjustment mechanism includes a vertical adjustment mechanism for driving the ball-serving mechanism to rotate vertically and a horizontal adjustment mechanism for driving the ball-serving mechanism to rotate horizontally.

[0010] The working principle of the above multi-directional and multi-angle tennis ball machine is as follows:

[0011] When working, a large number of tennis balls to be sent are first put into the ball storage box. Under the action of gravity, the tennis balls in the ball storage box automatically fall down into the hose, and then move along the hose to the ball-serving roller; at this time, the roller drive mechanism drives the ball-serving roller to rotate rapidly, thereby quickly throwing the tennis balls out and realizing automatic serving.

[0012] Furthermore, the vertical adjustment mechanism can be used to drive the serving mechanism to rotate vertically, allowing the angle of the tennis ball to be freely adjusted according to actual needs; the horizontal adjustment mechanism can be used to drive the serving mechanism to rotate horizontally, allowing the direction of the tennis ball to be freely adjusted. The flexibility of the hose allows it to adapt to the pitch and horizontal rotation of the serving mechanism, ensuring that the tennis ball can be smoothly delivered to the serving mechanism at various serving angles.

[0013] In a preferred embodiment of the present invention, the roller drive mechanism includes a roller drive motor provided on the serving rack, and two roller drive motors are provided and respectively connected to the two serving rollers.

[0014] In a preferred embodiment of the present invention, the serving mechanism further comprises a ball receiving hopper fixedly mounted on the serving rack, the upper end of the hopper being connected to the hose, and the lower end of the hopper extending between the two serving rollers. This structure allows tennis balls to be accurately received from the hose and transferred between the two serving rollers.

[0015] In a preferred embodiment of the present invention, the vertical adjustment mechanism includes a vertical mounting frame, a vertical drive motor, and a vertical transmission assembly; the vertical drive motor is mounted on the vertical mounting frame, and the axis of the output shaft of the vertical drive motor extends horizontally; the serving rack is rotatably connected to the vertical mounting frame; and the vertical transmission assembly includes a driving gear and a driven gear, the driving gear being mounted on the output shaft of the vertical drive motor, and the driven gear being mounted on the serving rack, the center of the driven gear coinciding with the rotational center of the serving rack. With this structure, the serving rack can be driven by the vertical drive motor to rotate in a vertical plane, thereby adjusting the launch angle.

[0016] Furthermore, the driven gear is a partial gear structure so as to reduce the occupied space and be more compact.

[0017] In a preferred embodiment of the present invention, the horizontal adjustment mechanism includes a horizontal drive motor and a horizontal transmission assembly; the axis of the output shaft of the horizontal drive motor extends vertically; the horizontal transmission assembly includes a belt and a pulley; two pulleys are provided, one of which is connected to the vertical mounting frame of the vertical adjustment mechanism, and the other is connected to the output shaft of the horizontal drive motor; the belt is connected to the two pulleys. Through this structure, the vertical mounting frame can be driven to rotate horizontally under the drive of the horizontal drive motor, thereby adjusting the launch direction.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The multi-directional and multi-angle tennis serving machine of the utility model adopts a soft pipe to transport tennis balls, so that it can adapt to the pitching and horizontal rotation of the serving mechanism, ensuring that the tennis balls can be smoothly transported to the serving mechanism under various serving angles. It has good flexibility and can meet the needs of multi-directional and multi-angle serving. BRIEF DESCRIPTION OF THE DRAWINGS
