[0024] 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.

[0025] Please see Figure 1-4 A tennis ball recovery device for tennis training includes a collection box 1, a controller 2 on the outside of the collection box 1, a discharge plate 3 on the top of the collection box 1, a ball-scoring port 4 in the inner wall of the bottom of the outside of the collection box 1, and a ball-scoring mechanism 5 on the outside of the collection box 1.

[0026] The goal-scoring mechanism 5 includes a shovel plate 51, a baffle plate 52 fixedly connected to the outer side of the shovel plate 51, a connecting plate 53 fixedly connected to the top of the baffle plate 52, a support plate 54 fixedly connected to the top of the connecting plate 53, a first motor 55 arranged on the outer side of the support plate 54, a rotating shaft 56 fixedly connected to the output end of the first motor 55, a nylon rope 57 wound around the outer side of the rotating shaft 56, a toggle plate 58 fixedly connected to one end of the nylon rope 57, a rotating component 59 arranged at the tail end of the baffle plate 52, a first stabilizing plate 510 fixedly connected to the outer side of the baffle plate 52, a return spring 511 fixedly connected to the outer side of the first stabilizing plate 510, and a second stabilizing plate 512 fixedly connected to the end of the return spring 511 away from the first stabilizing plate 510.

[0027] Furthermore: the shovel plate 51 is fixedly connected to the outside of the collection box 1, and the shovel plate 51 is located directly below the ball inlet 4. The baffles 52 are symmetrically distributed on the outside of the shovel plate 51. The actuating plate 58 is movably connected to the outside of the baffle 52 through the rotating part 59, and the initial position of the actuating plate 58 is on the same horizontal plane as the baffle 52. The nylon rope 57 has two tail-end winding joints, which are fixedly connected to the top of the two actuating plates 58 respectively. The second stabilizing plate 512 is fixedly connected to the outside of the actuating plate 58.

[0028] It should be noted that: Collection box 1 can be made of high-strength engineering plastics, such as polypropylene (PP) or polyethylene (PE). These materials have good impact resistance and weather resistance, allowing for long-term use in outdoor environments. They are also lightweight, facilitating the movement and handling of the device. The shovel plate 51, baffle plate 52, and discharge plate 3 can be made of aluminum alloy. Aluminum alloy is lightweight, high-strength, and corrosion-resistant, effectively supporting and guiding the tennis balls, and is not prone to rust, extending its service life.

[0029] Specifically: the return spring 511 is made of high-quality spring steel, possessing good elasticity and fatigue strength, ensuring stable return of the actuating plate 58. The rotating component 59 can use a hinge made of copper alloy, which has good rotational flexibility and wear resistance, allowing the actuating plate 58 to rotate smoothly. The first stabilizing plate 510 and the second stabilizing plate 512 can be made of the same aluminum alloy as the baffle 52, and are fixed by welding or bolting to ensure a firm connection.

[0030] As a further improvement of this utility model, the collection box 1 is provided with a lifting mechanism 6. The lifting mechanism 6 includes a second motor 61. The output end of the second motor 61 is fixedly connected to a lead screw 62. The outer side of the lead screw 62 is threadedly connected to a collar 63. A lifting groove 64 is opened in the inner wall of the collection box 1. A connecting rod 65 is fixedly connected to the outer side of the collar 63. A ball collecting groove 66 is fixedly connected to the outer side of the connecting rod 65.

[0031] It should be noted that: the No. 2 motor 61 is fixedly connected to the top of the collection box 1, the lead screw 62 is rotatably connected to the inner wall of the collection box 1, the connecting rod 65 is slidably connected to the inside of the lifting groove 64, the initial position of the ball collecting groove 66 is lower than the ball inlet 4, and the ball collecting groove 66 is located directly below the discharge plate 3.

[0032] Furthermore, motors 55 (No. 1) and 61 (No. 2) can be DC geared motors, which have the advantages of stable speed and high torque, meeting the power output requirements of the device while consuming less energy. The rotating shaft 56 is made of stainless steel to ensure it is not easily deformed or worn during long-term rotation. The nylon rope 57 is made of high-strength, wear-resistant nylon fiber to ensure it is not easily broken when the actuating plate 58 is frequently pulled.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: In the tennis training court, the tennis balls hit by the players land in a scattered manner. The shovel plate 51 of the device is fixed on the outside of the collection box 1 and located directly below the ball inlet 4, which plays an initial role in collecting and guiding the tennis balls. When the tennis ball rolls onto the shovel plate 51, the baffles 52 symmetrically distributed on the outside of the shovel plate 51 prevent the tennis ball from rolling to the sides, ensuring that the tennis ball is concentrated within the range of the shovel plate 51, in preparation for the subsequent flicking operation.

[0035] Motor 55 on the outside of support plate 54 starts, and its output drives shaft 56 to rotate. Since nylon rope 57 is wound around the outside of shaft 56, and the two ends of nylon rope 57 are fixed to the top of two actuating plates 58 respectively, as shaft 56 rotates, nylon rope 57 is gradually wound up, thereby pulling actuating plates 58. Actuating plates 58 rotate outside of baffle 52 through rotating component 59, and start to lift upward from the initial position at the same horizontal plane as baffle 52. During the lifting process, actuating plates 58 scrape the plate. The tennis ball on 51 is flicked toward the ball hole 4. When the first motor 55 reverses, the nylon rope 57 is relaxed. Under the action of the return spring 511, the flicking plate 58 is reset. One end of the return spring 511 is connected to the first stabilizing plate 510, which is fixed to the outside of the baffle 52. The other end is connected to the second stabilizing plate 512, which is fixed to the outside of the flicking plate 58. This structure ensures that the flicking plate 58 can quickly return to its initial position when it is not pulled by the nylon rope 57, ready for the next flicking action.

[0036] When a tennis ball enters the collection box 1 through the inlet 4, the lifting mechanism 6 inside the collection box 1 starts working. The second motor 61 installed on the top of the collection box 1 starts, and its output end drives the lead screw 62 to rotate. The collar 63, which is threaded to the outside of the lead screw 62, moves up and down along the lead screw 62 due to the rotation of the lead screw 62. The connecting rod 65, which is fixedly connected to the outside of the collar 63, slides in the lifting groove 64 opened in the inner wall of the collection box 1, ensuring the stability and straightness of the movement of the collar 63. The ball collecting groove 66, which is fixedly connected to the outside of the connecting rod 65, is initially lower than the inlet 4. As the collar 63 descends, the ball collecting groove 66 also descends to below the inlet 4, catching the tennis balls entering from the inlet 4. When the ball collecting groove 66 has collected a certain number of tennis balls, the second motor 61 reverses, driving the lead screw 62 to rotate in the opposite direction, causing the collar 63 to rise, which in turn drives the ball collecting groove 66 to rise. The ball collecting groove 66 transfers the collected tennis balls upward to directly below the discharge plate 3, preparing for the tennis balls to be discharged.
