Description

Technical Field

[0001] This utility model belongs to the technical field of tennis training equipment, and in particular relates to an automatic ball receiving and serving device. Background Technology

[0002] The existing operating venues mainly use existing ball-serving machines on the market for ball-serving. The balls bounce off the screen and bounce back to the ball-collecting frame at the top of the ball-serving machine. Guided by the ramp, the balls are collected into the ball-collecting frame of the ball-serving machine for recycling.

[0003] Most ball-serving machines on the market are designed for a 24-meter tennis court. However, due to space limitations in a tennis hall, their length is generally around 12 meters. Ground serves will hardly simulate the scenario of playing against a real person (the actual height of a person's return ball is mostly around 1 meter at waist level, while the net height is 0.914-1.07 meters).

[0004] Because existing products on the market are used, the serving height is lower than the height of the net, making it impossible to launch high-speed smashes. The existing ball recovery solution causes the ball to fall into the ball collection frame after rebounding from the curtain and then into the ball storage frame of the ball machine. Due to the height limitation of the ball machine, the user's return ball has a high probability of hitting the front of the ball collection frame, resulting in a reduced ball recovery rate and thus reducing training efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an automatic ball receiving and receiving device that uses a chain conveyor to transport tennis balls upwards, thereby increasing the height of the ball serving machine so that the ball opening height is near the height of the net, which can simulate training the receiving of smashes.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model is an automatic ball receiving and launching device, including a chain conveyor, a housing, and a hopper. The housing has an inner frame, and the chain conveyor is located inside the housing. The chain conveyor is placed vertically and has at least two conveying chains. A hopper includes a hopper body and two hopper frames. One end of the hopper frame is connected to the conveying chain, and the other end of the hopper frame is provided with a rotating shaft. The end of the rotating shaft is rotatably fitted into a hole on the side of the hopper body, and a hopper tilting limiter is installed on the rotating shaft.

[0008] The hopper is arranged in a ring on the conveyor chain, the hopper frame has an inward-folding plate, the plate is equipped with rigid limit and shock-absorbing columns, and the two sides of the hopper body are equipped with ear plates;

[0009] Limiting rollers are installed on the inner frame. The lifting path of the hopper is through the upper ear plate to abut the limiting rollers. A ball chamber is set at the upper end of the outer shell. The ball chamber has a ball receiving frame. When the ear plate abuts the limiting rollers, the hopper is inclined to the ball receiving frame.

[0010] Furthermore, a ball-launching machine is installed below the ball chamber, with the ball outlet of the ball chamber facing the ball-launching machine's receiving port.

[0011] Furthermore, a large screen is mounted on the frame, with a launch port on the screen.

[0012] Furthermore, a curtain panel is provided on the small frame, and a small curtain is suspended on the curtain panel. The small curtain has a blocking opening, the width of which is smaller than the width of the emission port.

[0013] Furthermore, the hopper tilting limiter is a torsion spring, with the straight end of the torsion spring connected to the hopper body and the hopper frame respectively.

[0014] Furthermore, the hopper has a row of teeth.

[0015] Furthermore, it also includes an upper ball frame, on which a row of slots are cut.

[0016] Furthermore, it also includes a driver, the chain conveyor includes a conveyor frame, the end of the conveyor frame is provided with a sprocket, the conveyor chain is wound around the sprocket, the conveyor frame is provided with a chain tensioner, and the output end of the driver is connected to the sprocket.

[0017] Furthermore, it also includes a ball-receiving ramp and a backplate:

[0018] The ball-receiving ramp has an inclined plate, and on both sides of the inclined plate are two support plates of different heights;

[0019] The back panel has side panels at both ends and a notch in the middle.

[0020] The ball-collecting ramp is placed below the large screen and against the back panel, with the notch close to a support plate with a smaller height.

[0021] Furthermore, it also includes a belt conveyor, with two ball-receiving ramps located on either side of the gap, and the belt conveyor positioned between the two ball-receiving ramps, with the ball-exiting end of the belt conveyor passing through the gap and placed on the upper ball frame.

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

[0023] The ball is launched from the ball launcher, and the trainee hits the ball onto the screen. The impact of the ball is absorbed by the screen and falls onto the ramp. The ramp, which has an inward and inward tilt, guides the ball to the conveyor belt in the middle. The conveyor belt sends the ball to the ball loading machine at the back of the screen, and then the ball loading machine transports the ball to the ball chamber at the top of the machine. The ball is then launched from the ball launcher, and the cycle continues.

[0024] When playing, in order to ensure that the ball does not pass through the service opening and enter the back of the curtain as much as possible, the service opening needs to be minimized. Therefore, a small curtain structure is set at the front of the service opening. When the service opening rotates left and right, the small curtain also swings left and right, narrowing the service opening into a racetrack-shaped opening, reducing the probability of the user hitting the ball into the service opening.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0038] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0039] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0040] Please see Figure 1-9 As shown, this utility model is an automatic ball launching and receiving device, wherein... Figure 2 One side panel of the outer shell 15 and Figure 3 The side panel of the ball chamber 11 is hidden. The ball machine 16 is installed behind the large screen 10 with the launch port. After the athlete hits the ball, the ball slides down the large screen 10 into the ball collection trough 2 placed below the large screen 10. The ball is then transported to the upper ball frame 3 by the belt conveyor 203. The hopper 4 of the upper ball machine lifts the tennis ball in the upper ball frame 3 upward. When it is lifted to the top of the chain conveyor 1, the hopper 4 flips, and the tennis ball falls into the ball chamber 11. The ball chamber 11 transports the tennis ball to the ball machine 16, and the ball machine 16 performs serving training.

[0041] A large screen 10 is mounted on the frame 6, and a transmission port is opened on the large screen 10.

[0042] Furthermore, a curtain panel 14 is provided on the small frame 13, and a small curtain 12 is suspended on the curtain panel 14. The small curtain 12 has a blocking opening 1201, the width of which is smaller than the width of the emission port.

[0043] The upper frame of the small frame 13 is equipped with a linear slide rail mechanism, and the curtain panel 14 is mounted on the sliding part of the linear slide rail mechanism.

[0044] The size of the ball-serving hole 101 of the large screen 10 is effectively controlled by the horizontal movement of the small screen 12, reducing the probability of hitting the ball into the gap of the ball-serving machine.

[0045] The specific details of the tennis training hall ball collection trough 2 of the double ball collection ramp 201 and single belt conveyor 203 are as follows:

[0046] The ball-retrieving ramp 201 has an inclined plate 206, with two support plates of different heights on both sides of the inclined plate 206; the back plate 202 has side plates 205 at both ends, and a notch 204 in the middle of the back plate 202; the large curtain 10 is erected above the back plate 202, the ball-retrieving ramp 201 is placed below the large curtain 10 and close to the back plate 202, and the notch 204 is close to the support plate with the lower height.

[0047] There are two ball-receiving ramps 201, which are located on both sides of the gap 204.

[0048] Furthermore, the conveyor belt 203 is located between the two ball-collecting ramps 201. The conveyor belt 203 passes through the gap 204. When the tennis ball falls down the ball-collecting ramp 201, it flows onto the conveyor belt 203. The ball-discharging end of the conveyor belt 203 passes through the gap 204 and is placed on the upper ball frame 3.

[0049] Additionally, brackets can be installed at both ends of the inclined plate 206 on the ball-receiving ramp 201 to replace the support plate, ensuring that the inclined plate 206 has an inclination.

[0050] Belt conveyor 203 is a belt-type belt conveyor, consisting of a motor, profiles, and head and tail sections located at both ends of the profiles. The conveyor belt is simply wound around the head and tail sections.

[0051] The outer casing 15 has an inner frame, and the chain conveyor 1 is located inside the outer casing 15. The chain conveyor 1 has a conveyor frame 101, and the end of the conveyor frame 101 is provided with a sprocket. Specifically, there are four sprockets, which form two conveyor chains. The two sprockets at the same end of the chain conveyor 1 are coaxially driven, and the two sprockets on the same side of the conveyor frame 101 are wound with a conveyor chain 102.

[0052] Preferably, a chain tensioner 7 is provided at the end of the conveyor frame 101 to facilitate periodic adjustment of the chain tension.

[0053] The driver is a motor, and the output end of the driver is connected to the shaft of the sprocket.

[0054] Furthermore, the conveyor frame 101 is provided with an intermediate baffle 5.

[0055] The hopper 4 is arranged in a loop on the conveyor chain 102.

[0056] A conveyor chain is connected to each side of the hopper 4. The hopper 4 is lifted by the chain conveyor 1. When the hopper 4 is lifted from the bottom, it passes through the upper ball frame 3 and hooks the tennis ball into the hopper 4 for lifting.

[0057] The hopper 4 includes a hopper body 402 and a row of teeth 404. Specifically, the teeth 404 are located on the front edge of the hopper body 402. A row of slots 301 are opened on the upper ball frame 3. The slots 301 formed on the upper ball frame 3 and the teeth 404 of the hopper 4 form interlocking teeth. That is, when the teeth 404 of the hopper 4 pass through the upper ball frame 3, they take away the tennis ball placed in the upper ball frame 3. The width of the slots 301 and the width between the two teeth 404 are smaller than the diameter of the tennis ball.

[0058] Bucket frame 403 is installed on both sides of bucket 4. One end of bucket frame 403 is connected to conveyor chain 102, and the other end of bucket frame 403 is provided with rotating shaft 405. The end of rotating shaft 405 is rotatably fitted in a hole on the side of bucket body 402, and bucket body 402 can rotate around rotating shaft 405.

[0059] A hopper tilting limiter 6 is installed on the rotating shaft 405. The hopper tilting limiter 6 is a torsion spring, and the straight end of the torsion spring is connected to the hopper body 402 and the hopper frame 403 respectively.

[0060] The bucket body 402 is provided with ear plates 401 on both sides. A pair of limiting rollers 9 are provided on the lifting path of the bucket body 402. The limiting rollers 9 are located on the pressure rod at the ball outlet. When the bucket 4 is raised to the ball release height, the ear plates 401 abut against the limiting rollers 9, and the bucket body 402 tilts to release the ball.

[0061] Limiting rollers 9 are installed on the inner frame. Specifically, limiting rollers 9 are installed on both sides of the inner frame at the top of the chain conveyor 1. The central shaft of the limiting rollers 9 is connected to the frame. The lifting path of the bucket 402 is through the upper ear plate 401 to abut the limiting rollers 9. A ball bin 11 is provided at the upper end of the outer shell 15. The ball bin 11 has a ball receiving frame. When the ear plate 401 abuts the limiting rollers 9, the hopper 4 is inclined to the ball receiving frame.

[0062] A ball machine 16 is installed below the ball chamber 11, with the ball outlet of the ball chamber 11 facing the ball receiving port of the ball machine 16.

[0063] Additionally, the bucket frame 403 has an inwardly folding plate with a rigid limiting shock absorber 8 on it. The rigid limiting shock absorber 8 limits the rotation range of the bucket body 402. When the ear plate 401 disengages from the limiting roller 9, the bucket body 402 returns to its original position. When the rigid limiting shock absorber 8 collides with the hopper 4, it can effectively reduce the impact and noise caused by the rebound.
