Description

Technical Field

[0001] This invention belongs to the field of sports equipment technology, and specifically relates to an automatic collection device for ball sports equipment. Background Technology

[0002] Ball sports are widely popular worldwide, including football, basketball, tennis, and golf. These sports typically require a large number of balls for training and matches, and the collection, storage, and management of these balls has always been a challenging task. Most existing ball collection devices are designed for balls of a specific diameter, lacking flexibility and adaptability, and unable to handle balls of different diameters simultaneously.

[0003] Chinese utility model patent CN214597090U discloses a convenient retrieval and placement mechanism for a ball storage device for sports equipment. The device includes a collection box with ball outlet and ball inlet holes. Two guide plates are fixedly connected to the inner wall of the collection box, and two sets of symmetrical casters are fixedly connected to the bottom surface. While this utility model can collect balls, it cannot classify and collect different types of balls, still requiring manual sorting. To address these issues, this invention provides an automatic ball sports equipment collection device. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention provides an automatic collection device for ball sports equipment, comprising a mobile vehicle, a launching mechanism, a collection mechanism, and an opening and closing mechanism.

[0005] The ejection mechanism is mounted on the mobile vehicle body. The ejection mechanism includes a collection bucket and a stabilizing bucket that are connected to each other. The collection bucket and the stabilizing bucket are mounted on the mobile vehicle body. An ejection assembly is provided below the stabilizing bucket. The ejection assembly is used to eject the ball into the collection mechanism.

[0006] The collection mechanism is installed on the mobile vehicle body. The collection mechanism includes a through pipe, one end of which is located inside the stabilizing barrel, and the other end of which is installed on the collection box, which is installed on the mobile vehicle body.

[0007] There are five opening and closing mechanisms, which are installed on the collection box.

[0008] Furthermore, the ejection assembly includes a tray with two symmetrically arranged limiting grooves. The central axis of the tray coincides with the central axis of the stabilizing barrel. Four guide rods are fixedly installed below the tray. The guide rods slide in cooperation with the moving vehicle body. A return spring is sleeved on the outer ring of the guide rod. The return spring is located between the moving vehicle body and the tray. The tray is connected to a pulling assembly, which compresses the return spring by pulling the tray.

[0009] Furthermore, the pulling assembly includes a friction wheel and two symmetrically arranged connecting blocks. Two ropes are connected to one end of each connecting block. The other end of each rope passes through the center of the guide rod and is fixedly connected to the lower end of the tray. A boss is provided on the side of the connecting block near the central axis of the tray. The friction wheel is located below the moving vehicle body and a locking plate is provided on the friction wheel.

[0010] Furthermore, the ejection mechanism also includes a limiting component, which includes two symmetrically arranged limiting rods. A locking connector is provided above the limiting rods, and one end of the limiting rod is connected to a sliding rod below. The other end of the sliding rod is mounted on a connecting frame. The connecting frame is coaxially and fixedly connected to the ejection rod. The ejection rod is slidably mounted on the moving vehicle body. An ejection plate is fixedly mounted above the ejection rod, and a return spring is provided between the ejection plate and the moving vehicle body.

[0011] Furthermore, the ejection mechanism also includes two symmetrically arranged guide blocks, which are slidably engaged with the limiting rod. When the locking connector on the limiting rod slides to the tray, the locking connector is slidably engaged with the limiting groove.

[0012] Furthermore, the ejection mechanism also includes a motor, which is fixedly mounted on the moving vehicle body. The output shaft of the motor is fixedly mounted with a drive wheel, which meshes with a driven wheel. The driven wheel and the second friction wheel are coaxially mounted on the moving vehicle body, and the first friction wheel is rotatably mounted at the lower end of the ejection rod.

[0013] Furthermore, the collection mechanism also includes a first pipe, a second pipe, a third pipe, and a fourth pipe. The upper ends of the first pipe, the second pipe, the third pipe, and the fourth pipe are connected to a connecting pipe. The interior of the collection box is divided into five independent spaces, which are respectively connected to the lower ends of the connecting pipe, the first pipe, the second pipe, the third pipe, and the fourth pipe. The diameters of the first pipe, the second pipe, the third pipe, the fourth pipe, and the connecting pipe increase sequentially. The first pipe, the second pipe, the third pipe, and the fourth pipe are arranged sequentially along the long side of the collection box.

[0014] Furthermore, each independent space on the collection box is equipped with a rotating wheel, which is rotatably installed inside the collection box. The outer ring of the rotating wheel is equipped with blades, and the inner ring of the rotating wheel and the inner wheel form a ratchet and pawl engagement. The inner wheel is coaxially fixedly installed on a rotating shaft, which is rotatably installed inside the collection box. A lifting head is threadedly fitted above the rotating shaft, and the lifting head is slidably engaged with a vertical rod, which is fixedly installed on the collection box.

[0015] Furthermore, the five opening and closing mechanisms correspond to five independent spaces on the collection box. Each opening and closing mechanism includes a hinge, which is fixedly installed on the outside of the collection box. One end of a through-tube is rotatably installed on the hinge. A pin is slidably installed on the opening and closing door. Two short posts are slidably installed on the opening and closing door. A return spring three is sleeved on the outer ring of the short posts. The return spring three is located on the side of the opening and closing door closer to the collection box.

[0030] To better illustrate the embodiments of the present invention, some parts in the accompanying drawings may be omitted, enlarged, or reduced, and do not represent the actual size of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0031] Example: Figure 1 — Figure 11 The automatic collection device for ball sports equipment shown includes a mobile vehicle 1, as well as a catapult mechanism 2, a collection mechanism 3, and an opening and closing mechanism 4.

[0032] The ejection mechanism 2 is installed on the mobile vehicle body 1. The ejection mechanism 2 includes a collection bucket 201 and a stabilizing bucket 202 that are connected to each other. The collection bucket 201 and the stabilizing bucket 202 are installed on the mobile vehicle body 1. An ejection assembly is provided below the stabilizing bucket 202. The ejection assembly is used to eject the ball into the collection mechanism 3.

[0033] The collection mechanism 3 is installed on the mobile vehicle body 1. The collection mechanism 3 includes a pipe 301. One end of the pipe 301 is located inside the stabilizing tank 202, and the other end of the pipe 301 is installed on the collection box 311. The collection box 311 is installed on the mobile vehicle body 1.

[0034] There are five opening and closing mechanisms 4, which are installed on the collection box 311.

[0035] The ejection assembly includes a tray 203, on which two symmetrically arranged limiting grooves 218 are provided. The central axis of the tray 203 coincides with the central axis of the stabilizing barrel 202. Four guide rods 204 are fixedly installed below the tray 203. The guide rods 204 are slidably engaged with the moving vehicle body 1. A return spring 205 is sleeved on the outer ring of the guide rods 204. The return spring 205 is located between the moving vehicle body 1 and the tray 203. The tray 203 is connected to a pulling assembly. The pulling assembly compresses the return spring 205 by the tray 203.

[0036] The pulling assembly includes a friction wheel 209 and two symmetrically arranged connecting blocks 219. One end of two ropes 221 is connected to each connecting block 219. The other end of the ropes 221 passes through the center of the guide rod 204 and is fixedly connected to the lower end of the tray 203. A boss 220 is provided on the side of the connecting block 219 near the central axis of the tray 203. The friction wheel 209 is located below the moving vehicle body 1, and a locking plate 210 is provided on the friction wheel 209.

[0037] The ejection mechanism 2 also includes a limiting assembly, which includes two symmetrically arranged limiting rods 212. A snap-fit ​​connector 213 is provided above the limiting rods 212. The lower end of the limiting rods 212 is connected to one end of the slide rod 211. The other end of the slide rod 211 is mounted on the connecting frame 223. The connecting frame 223 is coaxially fixedly connected to the ejection rod 207. The ejection rod 207 is slidably mounted on the moving vehicle body 1. An ejection plate 206 is fixedly mounted above the ejection rod 207. A return spring 208 is provided between the ejection plate 206 and the moving vehicle body 1.

[0038] The ejection mechanism 2 also includes two symmetrically arranged guide blocks 222. The guide blocks 222 are slidably engaged with the limiting rod 212. When the locking connector 213 on the limiting rod 212 slides to the position of the tray 203, the locking connector 213 is slidably engaged with the limiting groove 218.

[0039] The ejection mechanism 2 also includes a motor 217, which is fixedly mounted on the moving vehicle body 1. The output shaft of the motor 217 is fixedly mounted with a drive wheel 216, which meshes with a driven wheel 215. The driven wheel 215 and the second friction wheel 214 are coaxially mounted on the moving vehicle body 1, and the first friction wheel 209 is rotatably mounted on the lower end of the ejection rod 207.

[0040] The collection mechanism 3 also includes a first pipe 302, a second pipe 303, a third pipe 304, and a fourth pipe 305. The upper ends of the first pipe 302, the second pipe 303, the third pipe 304, and the fourth pipe 305 are connected to the connecting pipe 301. The interior of the collection box 311 is divided into five independent spaces, which are respectively connected to the lower ends of the connecting pipe 301, the first pipe 302, the second pipe 303, the third pipe 304, and the fourth pipe 305. The diameters of the first pipe 302, the second pipe 303, the third pipe 304, the fourth pipe 305, and the connecting pipe 301 increase sequentially. The first pipe 302, the second pipe 303, the third pipe 304, and the fourth pipe 305 are arranged sequentially along the long side of the collection box 311.

[0041] Each independent space on the collection box 311 is equipped with a rotating wheel 306. The rotating wheel 306 is rotatably installed inside the collection box 311. The outer ring of the rotating wheel 306 is provided with blades. The inner ring of the rotating wheel 306 and the inner wheel 307 form a ratchet and pawl engagement. The inner wheel 307 is coaxially fixedly installed on the rotating shaft 309. The rotating shaft 309 is rotatably installed inside the collection box 311. A lifting head 308 is threadedly engaged above the rotating shaft 309. The lifting head 308 is slidably engaged with the vertical rod 310. The vertical rod 310 is fixedly installed on the collection box 311.

[0042] Five opening and closing mechanisms 4 correspond to five independent spaces on the collection box 311. Each opening and closing mechanism 4 includes a hinge 402, which is fixedly installed on the outside of the collection box 311. One end of a tube 301 is rotatably installed on the hinge 402. A pin 405 is slidably installed on the opening and closing door 401. Two short posts 403 are slidably installed on the opening and closing door 401. A return spring 3 404 is sleeved on the outer ring of the short posts 403. The return spring 3 404 is located on the side of the opening and closing door 401 near the collection box 311.

[0043] Working principle: When collecting balls, the staff pushes the mobile vehicle 1 to move on the ground. When it reaches the area where various balls are piled up, the mobile vehicle 1 stops moving and then puts the various balls on the ground, such as basketballs and volleyballs of different diameters suitable for different age groups, into the collection bucket 201. The collection bucket 201 is connected to the stabilizing bucket 202. In this way, the balls that enter the collection bucket 201 will roll into the stabilizing bucket 202. The ejector plate 206 is located inside the stabilizing bucket 202, and the weight of the balls will press down on the ejector plate 206.

[0044] As the ejection plate 206 is subjected to gravity, the ejection rod 207 below the ejection plate 206 slides downward along the moving vehicle body 1. The connecting frame 223, which is coaxially fixedly connected to the ejection rod 207, also moves downward. This causes the slide rod 211, which is rotatably connected to the connecting frame 223, to push the limiting rod 212, causing the limiting rod 212 to slide along the guide block 222. As a result, the locking connector 213 above the limiting rod 212 gradually comes out of the limiting groove 218 on the tray 203, and the locking connector 213 eventually leaves the limiting groove 218, thus releasing the tray 203 from restriction. At the same time, as the ejection plate 206 and the ejection rod 207 move downward, the friction wheel 209 rotatably mounted below the ejection rod 207 also moves downward. This causes the locking plate 210 on the friction wheel 209 to also move downward. During this process, the return spring 208 is compressed. The function of the return spring 208 is to assist in the reset of the ejection plate 206.

[0045] When friction wheel 209 moves downward below friction wheel 214 and tray 203 is released from its restraint, the spring force of return spring 205 will cause tray 203 to move upward (in the initial state, return spring 205 is compressed). The upward-moving tray 203 will bounce the ball on tray 203 upward. Since one end of the tube 301 is located inside the stabilizing barrel 202 and above tray 203, the ball will be bounced into the tube 301. The ball that enters the tube 301 will move along the inner wall of the tube 301.

[0046] like Figure 1 The diameters of the first pipe 302, the second pipe 303, the third pipe 304, the fourth pipe 305, and the connecting pipe 301 increase sequentially. Therefore, the ball with the smallest diameter will fall into the first pipe 302 first, the ball with the second smallest diameter will fall into the second pipe 303, and so on. The ball with the largest diameter will enter the position where the connecting pipe 301 contacts the collection box 311.

[0047] After balls of different diameters enter different independent spaces within the collection box 311, the falling balls will touch the rotating wheel 306, causing it to rotate. The rotating wheel 306 and the inner wheel 307 form a ratchet-pawl engagement, causing the inner wheel 307 to rotate and thus the rotating shaft 309 to rotate. At this time, the lifting head 308, which is threadedly engaged with the rotating shaft 309, will slide upward along the vertical rod 310. This allows the staff to judge the number of balls collected by observing the height of the lifting head 308 outside the collection box 311. The ratchet-pawl engagement of the rotating wheel 306 and the inner wheel 307 is designed to prevent the balls from bouncing in the independent spaces, causing the rotating wheel 306 to drive the inner wheel 307 to rotate, thereby causing the lifting head 308 to move.

[0048] After collecting the balls in the independent space of the collection box 311, the staff removes the latch 405 from the opening and closing door 401. This removes the restriction between the opening and closing door 401 and the collection box 311. Under the elastic force of the return spring 404, the opening and closing door 401 will be opened and rotate on the hinge 402. Then, the staff can store the various balls of different diameters in the collection box 311 accordingly, thus completing the collection.

[0049] After the balls in tray 203 are ejected into pipe 301, ejection plate 206 is no longer under pressure. Thus, ejection plate 206 returns to its initial state under the action of return spring 208. Ejection rod 207 then moves upward, and friction wheel 209 also moves upward. Friction wheel 209 moves back to a plane aligned with friction wheel 214. Then, motor 217 is started, causing its output shaft to drive drive wheel 216 to rotate. Driven wheel 216 meshes with driven wheel 215, causing driven wheel 215 and friction wheel 214 to rotate. Friction exists between friction wheel 214 and friction wheel 209, causing friction wheel 209 to rotate. At this time, the retaining plate 2 on friction wheel 209... 10 will lock the protrusion 220 on the connecting block 219, causing the connecting block 219 to rotate with the clamping plate 210. The clamping plate 210 causes the connecting block 219 to tighten the rope 221, thus pulling the tray 203, which is fixedly connected to the slide rod 211, and causing the guide rod 204 on the tray 203 to slide down along the moving vehicle body 1. During this process, the return spring 205 will be compressed to generate elastic force. When the elastic force of the return spring 205 is equal to the friction force between the guide rod 204 and the friction wheel 209, the friction wheel 209 can no longer rotate, thus completing the preparation before collection. When the ball is transported to the top of the tray 203 again, the tray 203 will bounce the ball up again under the elastic force of the return spring 205.
