Description

Technical Field

[0001] This utility model relates to the field of automatic tennis ball collection technology, and in particular to an automatic tennis ball collection device suitable for tennis matches. Background Technology

[0002] Tennis, as a popular sport, generates a large number of tennis balls scattered across the court, whether in professional matches, daily training, or casual recreation. To ensure the continuity and efficiency of training or matches, it is necessary to quickly and centrally collect these scattered tennis balls. Therefore, developing efficient and convenient tennis ball collection devices has significant practical value.

[0003] Currently, there are several tools available on the market to help collect tennis balls. A common one is the hand-pushed roller ball collector, which typically works by using a roller made of wire or flexible material. The roller is pushed manually, and when it passes over a tennis ball, the wire or flexible material deforms elastically, "swallowing" the ball into the roller. Another common tool is the ball-collecting tube, where the user holds a long tube, aligns the opening with the tennis ball on the ground, and presses down, using the tube's structure to wedge the ball into the tube. Additionally, there are simple carts with sweeping boards or baffles, allowing users to push the cart to gather the balls together for unified collection.

[0004] However, existing tennis ball collection devices still have significant inconveniences in use. The core problem is that, whether it's a roller ball collection cart or a cart with a sweeping board, they only complete the first step of gathering tennis balls from the ground into a collection basket below the device or at a lower level. When it's time to transfer these collected tennis balls to a standard, waist-high coach's serving cart or storage container, the user must interrupt the collection process, repeatedly bending over or squatting to remove the balls from the low collection basket by hand or with a shovel and pour them into the higher container. This process is not only time-consuming and laborious, but the frequent bending over also puts a huge strain and fatigue on the user's lower back, especially for coaches or court maintenance personnel who need to pick up balls for long periods of time. This greatly reduces the overall efficiency and comfort of tennis ball collection work. Therefore, an automatic tennis ball collection device suitable for tennis matches is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic tennis ball collection device suitable for tennis matches. It aims to improve upon existing tennis ball collection devices that only gather the balls at a low position, requiring users to repeatedly bend over to retrieve and store the balls. This process is not only time-consuming and laborious, but also inefficient, and the frequent bending over can easily lead to lower back fatigue for users.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic tennis ball collecting device suitable for tennis matches, comprising a mobile vehicle, a collecting ramp fixedly connected to one side of the outer wall of the mobile vehicle, a bracket fixedly connected to one side of the lower surface of the collecting ramp, a motor fixedly connected inside the bracket, and symmetrical transmission shafts rotatably connected inside the collecting ramp. The output end of the motor is fixedly connected to one end of one of the transmission shafts, a five-jaw dial fixedly connected to one side of the outer wall of each of the two transmission shafts, and gears fixedly connected to the other side of the outer wall of each of the two transmission shafts. The two gears mesh with each other, and a feeding assembly is installed inside the mobile vehicle.

[0007] The feeding assembly includes a collection box, the lower surface of which is fixedly connected to the upper surface of the mobile vehicle. A collection container is fixedly connected to the inner wall of the mobile vehicle. A transmission cylinder is fixedly connected to the bottom of the inner wall of the collection container.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a motor drives a transmission shaft to rotate, which in turn causes two gears to mesh and rotate. These two gears then drive a five-jaw dial to rotate, thus achieving the effect of transferring tennis balls collected inside the ramp to the collection box when the mobile vehicle moves. At this time, a second motor drives an auger blade to rotate, and the tennis balls are then transferred from the inlet to the transmission cylinder. Simultaneously, the auger blade guides the tennis balls through the outlet to the collection box, and the guide ramp quickly guides them into the collection box.

[0031] 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.

[0032] Reference Figures 1-4 An embodiment of this utility model provides an automatic tennis ball collection device suitable for tennis matches, comprising a mobile vehicle 1, a collection ramp 2 for collecting tennis balls from the ground to a feeding port fixedly connected to one side of the outer wall of the mobile vehicle 1, a support bracket 3 for supporting the collection ramp 2 fixedly connected to one side of the lower surface of the collection ramp 2, a motor 4 for providing power to the collection mechanism fixedly connected inside the support bracket 3, a transmission shaft 5 symmetrically arranged on the left and right sides rotatably connected inside the collection ramp 2, the output end of the motor 4 fixedly connected to one end of one transmission shaft 5, a five-jaw dial 6 for actively feeding tennis balls fixedly connected to one side of the outer wall of each of the two transmission shafts 5, and a gear 7 for transmitting power fixedly connected to the other side of the outer wall of each of the two transmission shafts 5, the two gears 7 meshing with each other to achieve synchronous reverse rotation, and a feeding assembly installed inside the mobile vehicle 1;

[0033] The feeding assembly includes a collection box 15 located on the upper part of the mobile vehicle 1 for easy ball retrieval. The lower surface of the collection box 15 is fixedly connected to the upper surface of the mobile vehicle 1. A collection box 8, which serves as a primary buffer, is fixedly connected to the inner wall of the mobile vehicle 1. A transmission cylinder 9 for vertically transporting tennis balls is fixedly connected to the bottom of the inner wall of the collection box 8. The outer wall of the transmission cylinder 9 penetrates the interior of the mobile vehicle 1 and the collection box 15. A second motor 10, which provides power for feeding, is fixedly connected to the upper surface of the transmission cylinder 9. An auger blade 11 is fixedly connected to the output end of the second motor 10. An outlet 12 is opened on the upper side of the interior of the transmission cylinder 9, and an inlet 13 is opened on the lower side of the interior of the transmission cylinder 9. A guide ramp 14, which serves as a guide, is fixedly connected to the outer wall of the transmission cylinder 9 near the outlet 12.

[0034] Specifically, when the mobile vehicle 1 is pushed, tennis balls on the ground enter the collection area via the collection ramp 2. Motor 1 4 drives two five-jaw dials 6 to rotate in opposite directions through gear 7, actively conveying and collecting the tennis balls into the collection box 8, and then dropping them from the inlet 13 into the bottom of the transfer cylinder 9. Subsequently, motor 2 10 drives the auger blades 11 to rotate, lifting the tennis balls in the transfer cylinder 9 upwards along the cylinder wall until they are discharged from the upper outlet 12. The discharged tennis balls slide along the guide ramp 14 into the high-positioned collection box 15.

[0035] Reference Figures 1-4 A motor 16, which provides power to the stirring mechanism, is fixedly connected to one side of the outer wall of the mobile vehicle 1. The output end of the motor 16 passes through the interior of the mobile vehicle 1 and the collection box 8 and is fixedly connected to a rotating shaft 17. A perforated plate 18 for tumbling tennis balls to shake off dust is fixedly connected to the outer wall of the rotating shaft 17. Multiple perforated plates 18 are arranged in a ring shape to enhance the stirring effect. A support plate 19 for supporting the mobile vehicle 1 is fixedly connected to the inner wall of the mobile vehicle 1. One side of the outer wall of the support plate 19 is fixedly connected to one side of the outer wall of the collection box 8. A collection and holding device is fixedly connected to the upper surface of the support plate 19. The dust collection box 20 holds dust, and a filter plate 21 is slidably connected inside the dust collection box 20 for easy cleaning and replacement. A transmission pipe 24 is fixedly connected to the upper side of the outer wall of the dust collection box 20 to guide the dust-laden airflow. One end of the transmission pipe 24 is fixedly connected to the upper side of the outer wall of the collection box 8. A fan 22 is fixedly connected to the bottom wall of the inner wall of the mobile vehicle 1 to provide airflow for the dust collection system. A collection pipe 23 is fixedly connected to the output end of the fan 22. The outer wall of the collection pipe 23 is installed through the inside of the support plate 19, and one end is fixedly connected to the lower side of the outer wall of the dust collection box 20 to discharge filtered clean air.

[0036] Specifically, when it is necessary to clean the tennis balls in the collection box 8, the motor 16 is started, driving the rotating shaft 17 and the multiple perforated plates 18 fixed thereon to rotate. The rotation of the perforated plates 18 continuously tumbles and agitates the tennis balls in the collection box 8, causing them to collide and rub against each other, thereby shaking off the dust adhering to the surface of the tennis balls. At the same time, the fan 22 is started, generating negative pressure inside the collection box 8, which draws the shaken-off dusty air through the transmission pipe 24 into the dust collection box 20. Inside the dust collection box 20, the airflow passes through the filter plate 21, and the dust is effectively trapped, while the clean air is discharged through the collection pipe 23. This design achieves cleaning the tennis balls while collecting them, improving the additional functions and practicality of the device.

[0037] Working Principle: When the automatic tennis ball collection device is needed, firstly, as the mobile vehicle 1 moves across the tennis court, the tennis balls scattered on the ground are guided onto the collection ramp 2. At this time, motor 4 is activated, driving one transmission shaft 5 to rotate. Through two meshing gears 7, motor 4 drives another transmission shaft 5 to rotate synchronously in the opposite direction. As the transmission shaft 5 rotates, the five-jaw dial 6 fixed on it actively guides and gathers the tennis balls entering the collection ramp 2 to the center, causing them to fall into the inlet 13 at the bottom of the collection box 8 and into the transmission cylinder 9. Then, motor 10 is activated, driving the auger blades 11 inside the transmission cylinder 9 to rotate. The spiral structure of the auger blades 11 vertically lifts the tennis balls from the lower inlet 13 along the inner wall of the cylinder until they are discharged from the upper outlet 12. The discharged tennis balls are guided by the guide ramp 14 and finally fall into the high-level collection box 15. This automated feeding process realizes the direct transfer of tennis balls from the ground to the high-level container, solving the problem of frequent bending over required for manual collection.

[0038] Secondly, by turning on motor 16, the rotating shaft 17 and multiple perforated plates 18 fixed thereon are rotated within the collection box 8. The continuous rotation of the perforated plates 18 tumbles and agitates the tennis balls inside the box, causing them to collide with each other and with the plates, shaking off the dust adhering to the surface. Simultaneously, the fan 22 is activated, generating a negative pressure airflow that draws the suspended dust in the collection box 8 into the dust collection box 20 through the transmission pipe 24. Inside the dust collection box 20, the dust-laden airflow passes through the filter plate 21, effectively filtering and trapping the dust, while the clean air is discharged through the collection pipe 23, thus completing the cleaning of the tennis balls and improving the overall practicality of the device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
