Description

Technical Field

[0001] The invention belongs to the field of sports, and in particular relates to a ball picking machine. Background Art

[0002] Existing handheld small-sized ball pickers, such as table tennis ball pickers, are designed to pick up many table tennis balls at once, eliminating the need to pick up balls again after practice, saving time and making it easier for players to practice table tennis. However, in reality, when playing table tennis outside of practice, players often only carry one table tennis ball, which needs to be picked up each time they play.

[0003] If the existing ball picker is used to pick up balls, such as the application with application number 2024305744224, since it is designed to pick up a lot of balls, the ball loading device of the ball picker is relatively large and inconvenient to carry; after picking up the ball, it is necessary to exchange both hands to lift the ball picker upwards and raise the ball loading device to a relatively high position before reaching out to take out the ball, which is inconvenient to use. Even if the balls are poured on the table, they still need to be picked up from the table, which reduces efficiency.

[0004] Application number CN202430035126.7, when in use, when the table tennis ball enters the cylinder from the lower end, the lower end of the entire telescopic cylinder must be tilted up, and then the ball rolls to the mouth of the handheld end, and then the ball is taken out from the mouth. This makes the lower end of the telescopic cylinder tilted up, which is a laborious lever, relatively laborious, and not suitable for long-term use.

[0005] For people with leg diseases, such as weak muscle strength, difficulty in standing up after squatting, or people with bad knee joints, squatting is harmful to the knee joints. These people still need a table tennis ball picker to play table tennis, but it is not suitable to use only one table tennis ball to play. Summary of the Invention

[0006] The technical problem to be solved by the present invention is: to address the deficiencies of the existing technology, to provide a ball picking machine, which is convenient for people to hit a ball, pick it up and continue playing, especially for people with leg diseases who find it inconvenient to squat or stand up, and is more suitable for picking up balls.

[0007] In order to achieve the purpose of the present invention, the following technical solutions are adopted:

[0008] The ball picking machine comprises a handle, a conveying mechanism and a ball clamp. The handle is cylindrical and connected to the conveying mechanism. The conveying mechanism is connected to the ball clamp. The conveying mechanism works to move the ball clamp upward or downward.

[0009] Further optimized: the conveying mechanism includes two rollers, two connecting rods and an endless conveyor belt, the two connecting rods are arranged spaced apart on the left and right, the upper ends of the two connecting rods rotate together to connect to one roller, and the lower ends of the two connecting rods rotate together to connect to another roller, and there is a connecting rod at each end of the left and right ends of the roller; the conveyor belt is sleeved on the two rollers, and at least one ball clamp is provided on the conveyor belt, and the ball picking machine also includes a battery and a motor to drive the roller to rotate.

[0010] Further optimized: a connecting strip is bonded to the conveyor belt, and the connecting strip is arranged along the width direction of the conveyor belt; and one end of the connecting strip away from the conveyor belt is bonded to the ball clamp.

[0011] Further optimized: the handles are placed horizontally on the left and right, and the lower part of the side wall is fixedly connected to the support rod by screws, and the lower end of the support rod is fixedly connected to the upper end of the left connecting rod by screws.

[0012] Further optimized: the handle is placed horizontally left and right, a cavity is provided in the handle, a battery and a motor are installed in the cavity, an opening is provided on the lower side of the handle side wall near the left end of the handle, the output shaft of the motor is connected to the driving shaft, the driving shaft is above the opening, the left end of the upper roller is connected to the driven shaft, and the driving shaft and the driven shaft are jointly connected with a drive belt.

[0013] Further optimized: the support rod is located on the right side of the opening.

DETAILED DESCRIPTION

[0027] The following is based on the attached Figure 1-Figure 7 A detailed description of the specific implementation of the present invention is given below.

[0028] Example

[0029] The present embodiment is a ball picking machine, such as Figure 1 As shown, it mainly includes a handle 1, a conveying mechanism 2 and a ball clamp 3. The handle 1 is placed horizontally and at the top. The conveying mechanism 2 is connected to the ball clamp 3. An arc block is set at the upper end of the support rod 14. The arc block is fixedly connected to the lower part of the left part of the side wall of the handle 1 by screws. The lower end of the support rod 14 is connected to the conveying mechanism 2. Figure 2 As shown, a sliding switch 12 for controlling the ball clamp 3 to move upward or downward is installed on the side wall of the handle 1. When the sliding switch 12 is pushed, the conveying mechanism 2 works to move the ball clamp 3 upward or downward.

[0030] The conveying mechanism 2 can be implemented in many ways, such as a pneumatic telescopic rod, but in order to improve the efficiency of picking up balls, the present invention adopts different technical features to implement it, specifically, Figure 3-Figure 6As shown, the conveying mechanism 2 includes two rollers 21, two connecting rods 22, and an endless conveyor belt 23. The two connecting rods 22 are spaced apart from each other. The upper ends of the two connecting rods 22 rotate together to connect one roller 21, and the lower ends of the two connecting rods 22 rotate together to connect the other roller 21. In other words, each roller 21 is provided with a connecting rod 22 at each end. The upper and lower ends of the connecting rods 22 are fixedly connected to collars. The ends of the rollers 21 are fixedly connected to cylindrical heads 211, which are rotatably connected to the corresponding collars. Of course, bearings are preferably provided between the two to reduce friction. The lower end of the support rod 14 is provided with an arc-shaped connecting block, which is fixedly connected to the collar at the upper end of the left connecting rod 22 by screws. The conveyor belt 23 is sleeved on the two rollers 21, and three ball clamps 3 are arranged on the conveyor belt 23. When one of the ball clamps 3 is at the bottom, one ball clamp 3 basically moves upward to a position where it is easier to reach. In this way, there are three ball clamps 3, and the belt can always move in one direction without having to turn back after clamping a ball each time; and after the telescopic rod is shortened to clamp the ball, it has to be extended again to prepare for the next time to clamp the ball. In this way, it has to wait for the extension, and the ball clamping efficiency is relatively low.

[0031] In order to reduce the vibration of the present invention, a cavity is provided in the handle 1 of the present invention, and the battery and the motor are installed in the cavity. When the motor rotates, the hand holds the handle 1, which is equivalent to strengthening the stability of the handle 1 and the motor to a certain extent, reducing the vibration of the motor and the handle 1, and thus reducing the vibration of the entire invention, thereby reducing the interference with picking up the ball.

[0032] like Figure 2 As shown, a charging port 13 is provided at the right end of the handle 1, an opening 11 is provided at the lower end of the side wall of the handle 1 (ie, near the left end in the figure), and the output shaft of the motor is connected to the driving shaft, which is located above the opening 11. Figure 5 and Figure 6 As shown, the cylindrical head 211 at one end (left end in the figure) of the upper roller 21 is fixedly connected to the conductive shaft 241 of the driven shaft 24. The driving shaft and the driven shaft 24 are connected together with the drive belt 4. Limiting edges can be set at both ends of the driven shaft 24 and the driving shaft so that the drive belt 4 cannot fall off. When the motor rotates, the driving shaft drives the driven shaft 24 to rotate through the drive belt 4, and the rotation of the driven shaft 24 drives the conveyor belt 23 to rotate, so that the ball picker can move up or down. For safety reasons, the support rod 14 is set next to the opening 11 and away from the end where the opening 11 is located. That is, the support rod is on the right side of the opening 11 in the figure. When the player uses the present invention, the hand and the drive belt 4 are separated by the support rod 14, so that the hand is not easily touched by the drive belt 4 and the hand will not be injured by the drive belt 4.

[0033] like Figure 7As shown, the ball clamp 3 includes two spaced-apart clamps 31 and a connecting plate 32 fixedly connected at the same end of the two clamps 31. The ball clamp 3 can also be a pneumatic clamp or other structure, but none of them is as simple in structure as the ball clamp 3 of the present invention, nor as easy to be injection molded or stamped as the ball clamp 3 of the present invention. In order to facilitate the connection between the ball clamp 3 and the conveyor belt 23, the conveyor belt 23 of the present invention is bonded with a connecting strip 231. The connecting strip 231 is arranged along the width direction of the conveyor belt 23, and the end of the connecting strip 231 away from the conveyor belt 23 is bonded to the connecting plate 32 of the ball clamp 3 (the end wall of the connecting plate 32 away from the clamps 31 is bonded). Since the width of the connecting strip 231 can be set relatively small, such as 2-5mm, the conveyor belt 23 part around the connecting strip 231 can bend smoothly when it rotates onto the roller 21, and will not be unable to bend due to the ball clamp 3. This makes it easier for the conveyor belt 23 to adhere tightly to the roller 21, so that the conveyor belt 23 can move smoothly; and when the conveyor belt 23 bends, it will not cause the ball clamp 3 to bend, and will not affect the ball clamping of the ball clamp 3.

[0034] The present invention can also bond soft clamping pads 33 to two adjacent walls of the two clamping plates. The clamping pads are made of sponge. The distance between the two clamping pads is set to 37-40 mm and the thickness is set to 2-5 mm. If the distance between the two clamping pads is set to 37 and the thickness of the clamping pads is 3 mm, balls with diameters of 38 mm, 40 mm, and 40+ mm can be clamped. In this way, basically all existing table tennis balls can be clamped.

[0035] The conveying mechanism is set to be long enough so that when picking up a ball, there is no need to bend over, squat, or lift the lower part very high like existing ball pickers. The ball can be easily picked up, reducing player consumption and making it easier for special groups to use. After picking up a ball, the handle and the conveying mechanism have a relatively large space between them, and the right side is not blocked. This allows the handle to be hung on the edge of the table tennis table. The center of gravity of the ball picker is below the range of the table, so the ball picker will not fall, making it convenient to pick up the ball directly after playing. The present invention can also be used to pick up badminton and golf balls, as long as the distance between the clamping pads is set according to the diameter of the ball.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
