Detailed Implementation

[0023] like Figures 1 to 23The image shows a ball-dispensing device for a golf tee machine, belonging to a partial device of the golf tee machine. It includes a base housing 1, an electric drive device 2, a lifting and positioning device 3, a lifting and controlling ball-dispensing device 4, a ball positioning recess 5, a ball detection device 6, and a ball-dispensing hole 7. The lifting and positioning device 3 and the electric drive device 2 are fixed on the base housing 1. The electric drive device 2 is movably connected to the lifting and controlling ball-dispensing device 4. The lifting and positioning device 3 is longitudinally movably connected to the lifting and controlling ball-dispensing device 4. The top of the lifting and controlling ball-dispensing device 4... A ball positioning recess 5 is provided, the recessed shape of which is adapted to the curved surface of a golf ball; a ball detection device 6 is fixed on the lifting and controlling ball delivery device 4, which is used to detect whether there is a ball in the ball positioning recess 5; a ball delivery hole 7 is opened on the top of the base housing 1, and the ball positioning recess 5 and the ball delivery hole 7 are vertically aligned; under normal conditions, the lifting and controlling ball delivery device 4 is retracted inside the base housing 1, and during operation, when the ball detection device 6 detects the ball positioning recess 5... When a golf ball is hit, the control program on the control circuit board 9 of the golf tee machine controls the electric drive device 2 to work. The electric drive device 2 drives the lifting control ball release device 4 to rise, with its upper end passing through the opening of the ball release hole 7. The golf ball is exposed at the top of the opening of the ball release hole 7, waiting to be hit. After the golf ball is hit, if the ball detection device 6 does not detect a golf ball in the ball positioning recess 5, the control program on the control circuit board 9 of the golf tee machine will control the electric drive device 2 to work in reverse. The electric drive device 2 drives the lifting control ball release device 4 to descend and retract. The ball detection device 6 continuously detects whether a ball has fallen into the ball positioning recess 5, waiting for the next operation. This structure facilitates automatic control of golf ball release, eliminating the need for manual ball retrieval and positioning. The ball position is the same every time, calibrating the ball release and improving the efficiency of golf playing. It helps players find the hitting position more easily, making it easier to find the correct position, develop a better feel for the swing, practice the standard swing, and fix the standard stance, etc. This product is installed underground for embedded use, hitting a flat surface, taking up little space and not affecting the game.

[0024] Further refinement of the preferred technical solution: The lifting and positioning device 3 is a lifting and positioning rod assembly 3A, which is vertically arranged. The top of the lifting and positioning rod assembly 3A is tightly connected to the top of the base housing 1, and the bottom of the lifting and positioning rod assembly 3A is tightly connected to the bottom of the base housing 1. A lifting and positioning control ball-ejecting device 4 is movably connected to the lifting and positioning rod assembly 3A. The lifting and positioning control ball-ejecting device 4 can only be lifted and lowered vertically relative to the lifting and positioning rod assembly 3A. The above is a further refined structure of the lifting and positioning device 3. This structure is simple, easy to position, easy to assemble, and low in cost. The lifting and positioning control ball-ejecting device 4 has good lifting and sliding properties and good stability.

[0025] Preferably, the lifting positioning rod assembly 3A consists of two metal round straight vertical rods, which are preferably made of stainless steel. The top of the metal round straight vertical rod is tightly fixed to the top of the base housing 1, and the bottom of the metal round straight vertical rod is tightly fixed to the bottom of the base housing 1. Two corresponding rod holes 411 are opened on one side of the lifting control ball release device 4, and the two metal round straight vertical rods pass through the two rod holes 411 to form a movable connection, which fits perfectly.

[0026] Further, in the preferred technical solution: the lifting control ball-ejecting device 4 is located inside the base housing 1, ensuring smooth lifting, preventing foreign objects from entering, and protecting internal components; the lifting control ball-ejecting device 4 includes a lifting seat 41, a short tube 42, and a spherical concave ring shell 43; the lifting seat 41 is made of ferrous metal or aluminum, has a certain weight, and provides better stability for lifting and sliding; the short tube 42 and the spherical concave ring shell 43 can be made of ferrous metal, aluminum, or plastic; the lifting seat 41 is movably connected to the lifting positioning device 3 (preferably: two pairs are provided on one side of the lifting seat 41). The corresponding rod hole 411, through which two metal round vertical rods pass to form a movable connection, and the lifting seat 41 is positioned and vertically slides up and down using the two metal round vertical rods; a short tube 42 is vertically fixed to one side of the lifting seat 41 with a screw assembly, and a ball concave ring shell 43 is integrally fixed to the top edge of the short tube 42. A ball entry space 44 is reserved between the ball concave ring shell 43 and the ball outlet hole 7 to allow the golf ball to fall into the ball positioning recess 5; the top of the ball concave ring shell 43 is the ball positioning recess 5; the lifting seat 41 is equipped with a screw assembly A ball detection device 6 is fixedly installed, and the ball detection device 6 is installed through the lifting seat 41. The ball detection device 6 is located at the bottom inner part of the short tube 42. When the golf ball falls into the ball positioning recess 5, the ball detection device 6 can vertically detect the presence of the ball. This structure is easy to detect golf balls, accurate, efficient, and unaffected by lifting and lowering. The diameters of the short tube 42 and the ball concave ring shell 43 are smaller than the ball outlet hole 7, so that it can be pushed out from the ball outlet hole 7. During the rise, the short tube 42 passes through the ball outlet hole 7, and the ball concave ring shell 43 passes through the top of the ball outlet hole 7. 43 pushes out of the ball outlet 7 and supports and fixes the golf ball, waiting to be hit; the concave ring shell 43 of the ball body positions, prevents rolling and falling of the golf ball after it falls in; the short tube 42 and the concave ring shell 43 of the ball body facilitate pushing the golf ball out of the ball outlet 7 from the top. When the structure rises, it has good stability in supporting the golf ball, the structure design is reasonable, and the lifting and lowering are flexible; the electric drive device 2 is movably connected to the lifting seat 41, and suitable components are set for movable connection. The electric drive device 2 drives the lifting seat 41 to rise and fall, so that the lifting and lowering control ball outlet device 4 as a whole can achieve lifting and lowering.

[0027] Preferably, a tube column 413 is inserted and clamped at the rod hole 411, and a metal round vertical rod passes through the tube column 413, which fits perfectly, increases the connection area, and makes the lifting more stable.

[0028] Preferably, the sphere detection device 6 is a radar detection sensor, photoelectric sensor, ultrasonic sensor, or infrared sensor, etc. For example, a photoelectric sensor is a mirror-reflective photoelectric sensor.

[0029] Further, in the preferred technical solution: the electric drive device 2 includes a DC motor 21, a pinion 22, a toothed drive belt 23, a large gear 24, a rotating swing arm 25, and a bearing 26. The large gear 24 serves to reduce speed. The DC motor 21 is fixedly connected to the inner wall of the base housing 1 using a screw assembly. The motor shaft end of the DC motor 21 is fixed with a pinion 22 using a nut or clamp. The toothed drive belt 23 meshes with the large gear 24. The pinion 22, the toothed drive belt 23, and the large gear 24 have toothed stages for anti-slip and accurate stroke. The large gear 24 is transversely connected to the inner wall of the base housing 1 via a gear shaft core (the gear shaft core is clamped or...). A nut is fixedly connected transversely to the inner wall of the base housing 1, and a large gear 24 is movably connected to the gear shaft. The inner wall of the large gear 24 is radially fixedly connected to a rotating swing arm 25 with a screw assembly. The rotating swing arm 25 has an axial sliding groove 251, and a bearing 26 is embedded in the sliding groove 251. The bearing 26 slides within the length of the sliding groove 251. The bearing 26 is connected transversely to the side wall of the lifting seat 41 via a shaft (the shaft is bolted and tightened transversely to the side wall of the lifting seat 41, and the bearing 26 is movably connected to the shaft). The above structure is reasonably designed, the gear rotation is stable, the lifting seat 41 is driven to lift stably, and it has good durability.

[0030] A stroke detection device 8 is provided between the base housing 1 and the lifting seat 41. The stroke detection device 8 is used to detect whether the lifting seat 41 has reached the correct lifting and resetting position. The stroke detection device 8 includes a light sensor 81 and a stroke sensing plate 82. The light sensor 81 is fixed to the bottom of the base housing 1 with screws, and the stroke sensing plate 82 is fixed to one side of the corresponding lifting seat 41 with screws. The light sensor 81 and the stroke sensing plate 82 work together to detect whether the lifting seat 41 has reached the correct lifting and resetting position. The above realizes automated reset detection control, which is accurate.

[0031] During operation, when a golf ball falls into the ball positioning recess 5, the ball detection device 6 can vertically detect the presence of a ball. The control program on the control circuit board 9 controls the DC motor 21 to drive the pinion 22 to rotate, the pinion 22 to drive the gear transmission belt 23 to rotate, the gear transmission belt 23 to drive the large gear 24 to rotate, and the large gear 24 to drive the rotating swing arm 25 to rotate circumferentially. When the large gear 24 drives the rotating swing arm 25 to rotate clockwise, the bearing 26 drives the lifting seat 41 to swing up through its shaft pin (since the large gear 24 is round, the rotating swing arm 25 will have a change in rotation angle during rotation, and the bearing 26 will automatically slide back and forth in the sliding groove 251 to adapt to the change in rotation angle), thereby causing the short tube 42 to rise synchronously, pushing the golf ball out of the ball outlet 7, waiting to be hit;

[0032] When the lifting seat 41 rises to its position, it presses against the inner top of the base housing 1, and the lifting seat 41 can no longer rise. The load voltage / current of the DC motor 21 suddenly increases (when the lifting seat 41 is rising and falling normally, the voltage / current of the DC motor 21 is stable and small, and the motor shaft of the DC motor 21 rotates normally. When the motor shaft of the DC motor 21 is obstructed and cannot rotate, the load voltage / current of the DC motor 21 suddenly increases). The voltage / current value exceeds the normal operating voltage / current value. The control program of the control circuit board 9 will detect the voltage / current value exceeding the normal operating voltage / current value, indicating that the lifting position is reached and the golf ball has been pushed out of the ball outlet hole 7. Then the control program of the control circuit board 9 will control the DC motor 21 to temporarily stop working.

[0033] When the ball is knocked away, the ball detection device 6 can vertically detect that the ball is gone. The control program of the control circuit board 9 controls the DC motor 21 to drive the pinion 22, the gear transmission belt 23, and the large gear 24 to rotate counterclockwise. The rotating swing arm 25 rotates counterclockwise synchronously. The bearing 26 drives the lifting seat 41 to swing down through its shaft pin, thereby causing the short tube 42 to descend synchronously. When the lifting seat 41 descends to the correct position, it will trigger the stroke detection device 8, indicating that the descent has been reset. The stroke detection device 8 will feed the signal back to the control program of the control circuit board 9. Then, the control program of the control circuit board 9 controls the DC motor 21 to stop working and wait for the next lifting operation, thus forming a lifting cycle.

[0034] The lifting seat 41 moves up and down in one round trip, and the swing angle of the rotating swing arm 25 is between 30 and 50 degrees. It can be set according to the actual situation, and the preferred swing angle is 45 degrees.

[0035] Preferably, when the lifting seat 41 descends to the correct position, the travel sensor 82 will cut off the light signal transmission source of the light sensor 81, and the light sensor 81 will receive a trigger signal, indicating that the descent and reset are complete.

[0036] Another option: Of course, a micro switch, proximity switch, magnetic switch, photosensitive switch, or other travel detector for the raised position can be fixedly installed on the inner top wall of the base housing 1 with screws and connected to the control circuit board 9. When the lifting seat 41 rises to its position, the lifting seat 41 presses against the travel detector on the inner top wall of the base housing 1. The travel detector will feed back a signal to the control program of the control circuit board 9, indicating that the ball has been pushed out of the ball outlet 7. Then the control program of the control circuit board 9 will control the DC motor 21 to temporarily stop working.

[0037] The base housing 1 is fixedly connected to a control circuit board 9 with screws. The control circuit board 9 is connected to the ball detection device 6, the DC motor 21, and the stroke detection device 8 via wires. The inner wall of the base housing 1 is surrounded by a protective cover to protect the control circuit board 9.

[0038] The base housing 1 includes at least a bottom wall panel 1A, a left wall panel 1B, a top wall panel 1C, and a right wall panel 1D. The bottom wall panel 1A, left wall panel 1B, top wall panel 1C, and right wall panel 1D are made of ferrous metal. The left side of the bottom wall panel 1A is integrally connected to the bottom side of the left wall panel 1B, and the right side is connected to the bottom side of the right wall panel 1D by screw assemblies. The bottom wall panel 1A and left wall panel 1B are L-shaped. The left and right sides of the top wall panel 1C are connected to the top sides of the corresponding left wall panel 1B and right wall panel 1D by screw assemblies. The top wall panel 1C has a top plate hole 1C1 in the middle. A ball outlet short tube 1E is fixed at the top plate hole 1C1 by screw assemblies. The through hole of the ball outlet short tube 1E is a ball outlet hole 7. The bottom wall panel 1A, left wall panel 1B, top wall panel 1C, and right wall panel 1D, when connected adjacently, form a rectangular shell structure with an internal cavity for installing the electric drive device 2, the lifting and positioning device 3, and the lifting and ball-ejecting control device 4, and for protecting these components. This is the basic structure of the base shell 1, and its structure is robust.

[0039] The top wall panel 1C is composed of two sections, front and rear; the ball-dispensing device of a golf ball machine also includes a base protective frame 10, the base protective frame 10 is provided with a long U-shaped groove 11, the base housing 1 is fixed in the long U-shaped groove 11 by screws for reinforcement and protection, and the base protective frame 10 is used for installation and fixing with external equipment.

[0040] like Figure 1 As shown: This product is installed as a whole in the ground and is used to lay artificial turf on the top of the top wall panel 1C. The artificial turf has holes cut into it, and the holes are perpendicular to the ball outlet holes 7. The top opening of the ball outlet holes 7 is basically level with the artificial turf.

[0041] A ball-dispensing device for a golf tee machine further includes a ball-feeding lane device 12; the ball-feeding lane device 12 is fixed to the right end of the base housing 1 by a screw assembly; the ball-feeding lane device 12 has a ball-feeding lane 12A inside, the ball-feeding lane 12A is an arc-shaped bend, the ball-feeding lane 12A is arranged in a sloping manner from low to high, the slope is between 25 degrees and 40 degrees; the outer end of the ball-feeding lane 12A is the ball-inlet end, the ball-feeding lane 12A is between the ball-inlet end and the ball positioning recess 5, the inner end of the ball-feeding lane 12A is close to and fits with the ball positioning recess 5, the golf ball enters the ball-feeding lane 12A from the ball-inlet end, is conveyed to the inner end of the ball-feeding lane 12A, and then rolls into the ball positioning recess 5 for temporary positioning, waiting to be lifted and dispensed;

[0042] The fairway feeding device 12 guides the golf ball upwards through the fairway 12A, preventing the ball from rolling randomly and ensuring it rolls along the designated fairway.

[0043] The ball supply device 12 is used in conjunction with the electric ball supply device of another part of the golf tee machine. The electric ball supply device pushes several golf balls sequentially upward from the ball supply channel 12A. The ball supply channel 12A, which is arranged in a sloping manner from low to high, prevents the golf balls from flowing randomly. The balls are pushed one by one upward, and then pushed forward again after each ball is served. Only one ball is pushed into the ball positioning recess at a time. The ball supply device 12 only provides a stable ball supply channel structure to deliver the ball to the ball positioning recess 5.

[0044] The ball supply device 12 includes a ball supply pipe assembly 12B, a left ball guard plate 12C, a left ball support plate 12D, a right ball guard plate 12E, and a right ball support plate 12F. The ball supply pipe assembly 12B is made of plastic; the left ball guard plate 12C and the left ball support plate 12D are integrally molded from plastic or metal; the right ball guard plate 12E and the right ball support plate 12F are integrally molded from plastic or metal; a reinforcing cross plate 12G is snapped and fixed between the left ball guard plate 12C and the right ball guard plate 12E; the ball supply pipe assembly 12B and the left ball support plate 12D... The right bearing ball plate 12F is gradually sloped upwards from low to high. The ball supply pipe assembly 12B is fixed to the right end of the base housing 1 by screws. The left ball guard plate 12C and the right ball guard plate 12E are arranged facing each other. The left bearing ball plate 12D is integrally fixed to the inner wall of the left ball guard plate 12C, and the right ball guard plate 12F is integrally fixed to the inner wall of the right ball guard plate 12E. The left and right bearing ball plates 12D and 12F are arranged facing each other and at the same height. The lengths of the left and right bearing ball plates 12D and 12F are the same. A ball groove 12H is formed between the right ball bearing plates 12F and the ball groove 12H. The ball supply channel assembly 12B and the ball supply channel 12B together form the ball supply channel 12A. The left ball bearing plates 12D and the right ball bearing plates 12F are arranged along the direction of the ball supply channel 12A. The outer end of the ball supply channel assembly 12B is the ball inlet, and the inner end of the ball supply channel assembly 12B is connected to the ball groove 12H. Not every golf ball is 100% perfectly round; some have errors and are not perfectly round. The inner wall of the ball supply channel assembly 12B contacts the golf ball. With a large contact area, the ball may roll to one side and slip during rolling. Therefore, a small ball groove 12H is set at the rear of the ball supply pipe assembly 12B. After the ball comes out of the pipe of the ball supply pipe assembly 12B, it enters the ball groove 12H. The ball is supported by the left ball bearing plate 12D and the right ball bearing plate 12F along their edges. The ball is partially exposed through the ball groove 12H. Its small contact area can support both perfectly round and non-perfectly round balls stably, preventing slippage and rolling to one side, allowing the ball to roll forward stably.

[0045] The ball supply pipe assembly 12B comprises an outer straight pipe 12B1, a pipe fixing plate 12B2, and an inner bent pipe 12B3. The inner bent pipe 12B3 is arranged inside the base housing 1. A through hole 12B21 is provided on the pipe fixing plate 12B2. The upper end of the outer straight pipe 12B1 is fixedly connected to the outer wall of the through hole 12B21 by screws, and the lower end of the inner bent pipe 12B3 is fixed to the inner wall of the through hole 12B21 by screws. The pipeline is formed by connecting the outer straight pipe 12B1, the plate through hole 12B21, and the inner bend 12B3. The pipe fixing plate 12B2 is fixedly connected to the wall of the left wall frame 1B via screw assemblies. The outer straight pipe 12B1 passes through the rear of the left wall frame 1B. Because the ball in the ball supply pipeline assembly 12B is curved and relatively long, it is not easy to form it as a single piece. Therefore, it is formed in two sections and then installed on the left wall frame 1B and connected together. The ball supply pipeline assembly 12B is made of metal or plastic. The outer straight pipe 12B1 and the inner bend 12B3 are existing products that can be directly installed after purchase, saving energy and reducing the cost of custom molding.

[0046] The inner top wall of the base housing 1 is fixed with a vertical lifting positioning column 13 by bolts. The lifting positioning column 13 is threadedly connected to the bolts. The lifting positioning column 13 can be adjusted in height relative to the bolts to adjust the error and make the lifting seat adapt. The lifting seat 41 has a column hole 412, which is perpendicularly corresponding to the lifting positioning column 13. The lifting positioning column 13 can be inserted into the column hole 412. The bottom end of the lifting positioning column 13 is conical. If the lifting seat 41 has a small deviation and is not centered, the conical shape can also be inserted into the column hole 412. The lifting positioning column 13 corrects the deviation of the lifting seat 41 and performs secondary positioning of the lifting seat 41 to achieve stable lifting.
