Detailed Implementation

[0023] like Figures 1 to 24As shown: A ball return collection and electric ball conveying device, belonging to the category of golf tee machines, includes a base housing 1 and an electric drive device 2. The base housing 1 can be composed of multiple housing parts and is made of ferrous metal, resulting in low cost. The main technical improvement of this product is that the ball return collection and electric ball conveying device also includes a rotating ball pushing device 3 and a fairway device 4. The top of the base housing 1 is provided with a recessed portion 1A, which is square and used to install the electric drive device 2, the rotating ball pushing device 3, and the fairway device 4, compressing space and reducing volume. The front of the base housing 1 is provided with an inwardly inclined guide ramp 1B. The inward-sloping design, with an inclination angle of 20 to 40 degrees, facilitates the natural rolling of the balls. The inward-sloping guide ramp 1B is rectangular, with a width of 15 to 30 centimeters, providing a wider area to collect the rolling balls and allow multiple balls to roll in simultaneously. The rotating ball-pushing device 3 is arranged in a flat, horizontal manner at the bottom of the recessed portion 1A, preferably horizontally. The rotating ball-pushing device 3 rotates clockwise and has several ball-holding openings 3A circumferentially. There are typically 8 to 15 ball-holding openings 3A, the number depending on the diameter of the rotating ball-pushing device 3. The ball-holding opening 3A is U-shaped, gradually widening slightly from the inside out to facilitate the golf ball's entry and exit. The opening 3A is slightly larger than the diameter of the golf ball. Several openings 3A are arranged in a circular pattern, located close to the inner slope of the inward-sloping guide ramp 1B for easy entry of the golf ball. The inner surface of the opening 3A is smooth and will not scratch the ball. A ball-accommodating space 5 is provided between the rotating ball-pushing device 3 and the inner bottom wall of the base shell 1, allowing the golf ball to easily embed itself into the opening 3A. The height between the opening 3A and the inner bottom wall of the base shell 1 is approximately the height of a golf ball. The radius of the ball is such that the ball-holding opening 3A is precisely positioned at the center axis of the golf ball to facilitate its rolling and prevent it from slipping off. The inner wall of the recessed portion 1A is equipped with a ball-passing device 4, which escorts the ball outwards. Inside the ball-passing device 4 is a ball-transporting channel 4A, used for outputting the ball. The inner end of the ball-transporting channel 4A is located on one side wall of the recessed portion 1A and mates with the ball-holding opening 3A. The electric drive device 2 is connected to the rotating ball-pushing device 3, driving it to rotate circumferentially. The electric drive device 2 is fixedly connected to the base housing 1 via a metal bracket 6. The metal bracket 6 can also be replaced with a plastic bracket.This product is installed in golf practice rooms, practice sheds, and driving ranges, embedded underground. The artificial turf on the ground slopes towards the golfer (standing position). The artificial turf has return channels that connect to the inner inclined guide ramp 1B for natural ball return and collection. Each shot generates numerous balls, which are continuously hit and naturally collected back to the inner inclined guide ramp 1B. During operation, the electric drive unit 2 drives the rotating ball-pushing device 3 to rotate circumferentially. Several ball-holding ports 3A also rotate circumferentially and change position synchronously. The rotating ball-pushing device 3 rotates cyclically (its rotation is relatively slow, approximately 4-6 revolutions per minute; the speed of the rotating ball-pushing device 3 can be adjusted via the electric drive unit 2). During the return of the ball, numerous balls will be collected. After rolling down the inward-sloping guide ramp 1B, the golf ball naturally falls into the empty ball-holding opening 3A. The inner bottom of the base shell 1 supports the golf ball. As the rotating ball-pushing device 3 rotates, the golf ball rolls forward synchronously on the inner bottom surface of the base shell 1. When the rotating ball-pushing device 3 rotates, it pushes / pushes the golf ball, causing it to roll forward synchronously. When the golf ball rolls to the inner end of the delivery lane 4A, it is pushed out of the ball-holding opening 3A by the inlet guide baffle 411 of the lane device 4, guiding the golf ball into the delivery lane 4A. During the cycle, the balls in the delivery lane 4A push the balls in front of them forward, one after another, until the golf ball is output from the other end of the delivery lane 4A, realizing ball collection and electric ball delivery. This ball collection and electric ball delivery device is an electric ball-dispensing device that collects golf balls and delivers them to a golf ball tee machine for golf hitting practice. The aforementioned structure facilitates the collection and electric delivery of golf balls, ensuring orderly and uncluttered output; it eliminates the need for manual ball retrieval, reducing hassle and improving collection efficiency. The electric, orderly ball delivery system prevents mishaps. The ball collection and electric delivery device is installed underground, occupying no surface space and not obstructing the swing.

[0024] Further, in the preferred technical solution: the rotating ball-pushing device 3 is a rotating ball-pushing plate 301, which is made of iron or steel and is circular. The rotating ball-pushing plate 301 is arranged in a flat manner at the bottom of the recess 1A. The rotating ball-pushing plate 301 is preferably placed horizontally. A ball-accommodating space 5 is reserved between the rotating ball-pushing plate 301 and the inner bottom wall of the base shell 1. The rotating ball-pushing plate 301 has several ball-holding openings 3A around its circumference. This is the specific structure of the rotating ball-pushing device 3. This structure is simple, low in cost, and occupies little space.

[0025] The electric drive device 2 includes a DC motor 21 and a gear reducer 22. The DC motor 21 and gear reducer 22 are existing product technologies. The motor shaft of the DC motor 21 is fixedly connected to the transmission input shaft of the gear reducer 22. The housing of the DC motor 21 is fixedly connected to the housing of the gear reducer 22 with screws. The transmission output shaft of the gear reducer 22 is fixedly connected to the center of the rotating ball-pushing plate 301. Preferably, the transmission output shaft of the gear reducer 22 is fixedly inserted through the center of the rotating ball-pushing plate 301, and the two are fixed by a nut assembly, either clamped or welded. The housing support of the gear reducer 22 is fixedly connected to the top of the metal bracket 6 by a nut assembly. The metal bracket 6 is arranged in the recessed portion 1A to reduce the height and overall volume of the machine. The top of the metal bracket 6 is also recessed to accommodate the DC motor 21 and gear reducer 22 to reduce the height. This is the specific structure of the electric drive device 2. This structure is simple, low-cost, provides slow power output, stable rotation, is versatile, and easy to install.

[0026] During operation, after the DC motor 21 starts working, the speed is reduced by the gear reducer 22. Then, the power output end of the gear reducer 22 drives the rotating push plate 301 to rotate. In this way, the rotating push plate 301 rotates slowly, making it easier for the golf ball to fall into the ball-holding hole 3A. The rotating push plate 301 rotates slowly under the operation of the DC motor 21 and the gear reducer 22, synchronously pushing / pushing the golf ball to roll forward.

[0027] The fairway device 4 includes an inlet guide frame 41 and a channel frame 42, which are connected together. The fairway device 4 is made of metal or plastic. A ball outlet 1C is provided on one side of the base shell 1. The inlet guide frame 41 is located above the rotating putter plate 301, with the bottom of the inlet guide frame 41 close to but not in contact with the top of the rotating putter plate 301. The vertical wall of the inlet guide frame 41 is an inlet guide baffle 411, designed to prevent the golf ball from continuing to rotate with the rotating putter plate 301, so as to guide the ball into the fairway 4A. The recessed portion The inner wall of 1A is fixedly connected to the inlet guide frame 41 and the channel frame 42 by screw assembly. The inlet guide frame 41 and the channel frame 42 are used to escort the ball out in an orderly manner. The inlet guide frame 41 and the channel frame 42 together with the base shell 1 form the ball conveying channel 4A. The ball conveying channel 4A is slightly larger than the diameter of the golf ball, allowing several golf balls to be pushed and rolled out in an orderly manner. The outer end of the ball conveying channel 4A connects to the ball outlet 1C. A short output tube 43 is welded or fixed with screws at the ball outlet 1C for use with the electric ball delivery device of the golf ball tee machine. It is the free end of the connection. When the golf ball rolls to the inner end of the ball conveying channel 4A, the inlet guide baffle 411 of the inlet guide frame 41 blocks the golf ball from rolling out / coming out of the ball jamming port 3A and guides the golf ball into the ball conveying channel 4A.

[0028] The top of the inlet guide frame 41 is connected to a ball anti-backflow elastic device 6. After the ball enters the inlet, the ball is pushed past the ball anti-backflow elastic device 6 by the rotational thrust of the rotating ball pusher 301. The elastic force of the ball anti-backflow elastic device 6 is very small, and the ball can be pushed past with a little force. After passing the ball anti-backflow elastic device 6, the ball enters the ball conveying channel 4A and cannot move backward. The ball is pushed forward in an orderly manner to prevent the ball from being disordered at the inlet and to ensure stable ball conveying.

[0029] The spherical anti-backflow elastic device 6 includes a torsion spring 61, a hooked long arm 62, a first bearing 63, and an arm opening 64. An arm opening 64 is provided at the top of the inlet guide frame 41. The torsion spring 61 is fixedly connected to the inner wall of the base housing 1 by bolts. The head of the hooked long arm 62 is movably connected to the bolts. One end of the torsion spring 61 clamps the hooked long arm 62, and the other end presses against the top of the inlet guide frame 41, giving the hooked long arm 62 a lever-like restoring elasticity. The hook body of the end of the hooked long arm 62 passes through the arm opening 64 and extends into the inlet. At the end of the hook body 62, a first bearing 63 is connected horizontally by a nail body. The circumference of the first bearing 63 contacts the ball. After the ball enters the entrance, the rotational pushing force of the rotating ball pushing plate 301 pushes the ball across the circumference of the first bearing 63. After the first bearing 63 contacts the ball, it will lift the long arm of the hook 62 and slide across it. After the ball slides across, the end of the long arm of the hook 62 and the first bearing 63 descend and reset, preventing the ball from moving backward. Overall, it has good elasticity, good reset, smooth sliding / pushing, long service life, and will not damage the ball.

[0030] The side wall of the inlet guide frame 41 is connected to a second bearing 412 by a screw assembly. The circumferential surface of the second bearing 412 contacts the ball. After the ball enters the inlet, it is smoothly propelled by the assistance of the second bearing 412, reducing the friction force that propels it forward.

The cover 7 covers the recessed part 1A. The cover 7 is fixedly connected to the top of the base shell 1 with a screw assembly. The front wall of the cover 7 is fixedly provided with a ball blocking component 71 with a screw assembly. The ball blocking component 71 protrudes forward to block the excess space at the top of the rotating ball pushing plate 301, preventing the ball from rolling into the space at the top of the rotating ball pushing plate 301, so that the golf ball can fall smoothly into the ball holding opening 3A.

[0032] A transition pad 1D is fixed between the inwardly inclined guide ramp 1B and the ball-holding port 3A. The transition pad 1D is fixedly connected to the front bottom wall of the base shell 1 by screws or welding. The inner edge of the transition pad 1D is an arc-shaped ring edge. The arc-shaped ring edge is smooth and does not damage the ball. The arc-shaped ring edge is adapted to several ball-holding ports 3A arranged in a circular row. The arc-shaped ring edge does not contact the rotating ball-pushing plate 301. The transition pad 1D is used to cover the front corner space of the base shell 1 to prevent the ball from getting stuck and to allow the ball to roll smoothly into the ball-holding port 3A.

[0033] A cornering auxiliary correction bearing 8 is longitudinally provided at the front left corner of the recessed part 1A.
