Description

Technical Field

[0001] This invention relates to the field of golf ball retriever technology, and more particularly to a fully automatic golf ball retriever. Background Technology

[0002] During the course of operation, golf balls are randomly scattered throughout the course over time, sometimes reaching hundreds of thousands at peak times. These golf balls must be collected daily, transported to the golf washing room, cleaned, and then recycled. The process of retrieving the golf balls requires golf ball retrievers.

[0003] Traditional ball retrievers are limited to collecting balls and have a single function. During operation, golf balls are first collected into small baskets attached to the retriever and then towed by other vehicles. Due to their limited capacity, they quickly fill up, at which point the retriever must stop operating. The balls are then manually transferred from the small baskets to a transfer frame, which is then manually moved off the course before being loaded onto a transport vehicle for transport to the golf washing room. This entire workflow is intermittent, inefficient, and significantly prolongs the operation time. All golf ball transfers require human intervention, consuming a large amount of manpower. With a large number of balls, the weight of the various baskets increases, further increasing the workload for the workers. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic golf ball retriever.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic golf ball retriever, comprising:

[0006] Frame,

[0007] Ball-collecting mechanisms are provided on both sides of the frame. The ball-collecting mechanisms are mounted on the unfolding mechanism. The unfolding mechanism drives the ball-collecting mechanisms to open to both sides, switching from a vertically placed storage state to a horizontally placed working state, so that the ball-collecting mechanisms come into contact with the ground and pick up the balls on the ground.

[0008] A ball-sweeping assembly is located in front of the front wheel of the frame, which transports the ball to the two ball-collecting mechanisms in operation, and then the ball-collecting mechanisms transport the ball to the conveying assembly at the bottom of the frame.

[0009] The conveying assembly is equipped with a cleaning component to clean and convey the balls. The output end of the conveying assembly is equipped with a spiral feeding mechanism, which conveys the balls into the ball storage box to complete the ball picking.

[0010] As a further description of the above technical solution: protective brackets are provided on the outer side and top of the frame, the ball sweeping assembly is installed on the protective brackets and the frame, the ball sweeping assembly includes a support frame, a telescopic rod is vertically arranged on the support frame, and a mounting plate is provided at the output end of the telescopic rod, which drives the mounting plate to reciprocate in the vertical direction.

[0011] As a further description of the above technical solution: the mounting plate is located in front of the front wheel, and a ball sweeping assembly is provided on the mounting plate. The ball sweeping assembly includes at least two ball sweeping brushes, and the two ball sweeping brushes rotate in opposite directions, so that the ball moves from both sides of the front wheel to the ball picking mechanism.

[0012] As a further description of the above technical solution: the unfolding mechanism is located above the input end of the conveying component. The unfolding mechanism includes a first base, with flipping arms on both sides of the first base. A lead screw is provided at the bottom of the first base, with a lead screw nut sleeved on the lead screw. A connecting arm is installed above the lead screw nut. The lead screw is rotated by a motor, thereby moving the connecting arm.

[0013] As a further description of the above technical solution: one side of the connecting arm is connected to the flipping arm, and guide rails and sliders are provided between the two sides of the flipping arm and the first base, so that the flipping arm can reciprocate in the vertical direction, thereby driving the ball-collecting mechanism to move.

[0014] As a further description of the above technical solution: the tilting boom includes a second base, and a first connecting rod and a second connecting rod are arranged above the second base. The first connecting rod and the second connecting rod are sequentially connected to both sides of the electric telescopic rod, and rotate about the connection point of the second base as the center, thereby driving the electric telescopic rod to move. The output end of the electric telescopic rod is connected to the ball-collecting mechanism, which switches the ball-collecting mechanism between a storage state and a working state, and adjusts the height of the ball-collecting mechanism from the ground through the electric telescopic rod.

[0015] As a further description of the above technical solution: the ball-collecting mechanism includes a third base, the top of which is provided with a limit baffle to prevent collision with the second base. The third base is provided with ball-collecting fins, and a spiral guide rod is provided on the side of the ball-collecting fins near the front end of the frame. A volumetric cavity is formed between the spiral guide rod and the third base. The ball-collecting fins collect and transport the balls into the volumetric cavity, which is then transported by the spiral guide rod. An output port is provided on the side of the third base near the frame, and the output port is located above the cleaning component, which transports the collected balls to the cleaning component for cleaning.

[0016] As a further description of the above technical solution: the conveying assembly includes a conveying frame, on which a chain rod assembly is provided. The chain rod assembly cooperates with a sprocket, and is driven by a motor to rotate, thereby conveying the ball. The cleaning assembly includes a first brush assembly and a second brush assembly, which are connected to the motor for rotational cleaning. The first brush assembly is located below the chain rod assembly, and the second brush assembly is located above the chain rod assembly. The ball is cleaned by the first brush assembly and the second brush assembly.

[0017] As a further description of the above technical solution: the cleaning component conveys the ball to the spiral feeding mechanism, the spiral feeding mechanism includes a housing, a turntable is provided at the bottom of the inner side of the housing to drive the ball to rotate inside the housing, and a pipeline is connected to the curved wall of the housing to convey the ball to the ball storage box.

[0018] As a further description of the above technical solution: a fan is installed on the protective bracket, and the fan is connected to the ball storage tank through a pipe to make the inner cavity of the ball storage tank negative pressure. The ball storage tank is connected to the spiral feeding mechanism through a pipeline to suck the ball into the ball storage tank.

[0019] The above technical solution has the following advantages or beneficial effects:

[0020] 1. Two ball-collecting mechanisms are designed to increase the working width of ball collection. They are installed on a lifting and rotating unfolding mechanism. When the vehicle is in transit, the ball-collecting mechanism first rises and leaves the ground, then rotates 90 degrees and retracts to fit closely against the vehicle's exterior wall, thereby reducing the overall width of the vehicle. This not only gives the vehicle better passability but also effectively prevents the ball-collecting mechanism from rubbing against other vehicles or exterior walls, thus increasing driving safety.

[0021] 2. After the balls are fed into the conveyor assembly, they are transported to the spiral feeding mechanism. Cleaning components are installed on both the upper and lower belt surfaces of the conveyor assembly. As the balls pass through, they are driven by differentially rotating brushes to obtain rotational power, thereby better cleaning off weeds, sand, and other debris adhering to the balls and transporting them to the ball storage tank. Once the tank is full, the vehicle can drive directly to the ball washing room to unload the balls, optimizing the transfer process and facilitating subsequent cleaning. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figures 1-5This invention provides an embodiment of a fully automatic golf ball retriever, comprising: a frame 1, ball-retrieving mechanisms 2 on both sides of the frame 1, the ball-retrieving mechanisms 2 being mounted on an unfolding mechanism 3, the unfolding mechanism 3 driving the ball-retrieving mechanisms 2 to open to both sides, switching from a vertically placed storage state to a horizontally placed working state, so that the ball-retrieving mechanisms 2 contact the ground and retrieve balls from the ground; a ball-sweeping assembly 4 is provided in front of the front wheel of the frame 1, which transports the balls to the two ball-retrieving mechanisms 2 in the working state, and the ball-retrieving mechanisms 2 transport the balls to a conveying assembly 5 at the bottom of the frame 1; a cleaning assembly 6 is provided on the conveying assembly 5 to clean and transport the balls, and a spiral feeding mechanism 7 is provided at the output end of the conveying assembly 5, which transports the balls to a ball storage box 8, completing the ball retrieval.

[0033] The vehicle features unfolding mechanisms on both sides of the frame. During ball retrieval, these mechanisms open, causing the ball-retrieval mechanism to unfold and fall to the ground. Simultaneously, the golf balls rise with the rolling ball-retrieval mechanism and are removed by the ball-removal plate. The golf balls converge from both sides towards the center, then flow into the conveying and cleaning components. While being conveyed forward, they are cleaned by a high-speed rotating brush assembly to remove dirt, sand, grass stems, and other contaminants. The cleaned golf balls are then conveyed into the spiral feeding mechanism. The golf retrieval vehicle is equipped with a ball storage box, which is vacuumed using a vortex blower. Connected to the outlet of the spiral feeding mechanism, the golf balls are sequentially sucked into the storage box. Once full, the unfolding mechanism retracts, and the ball-retrieval mechanism retracts into the frame, reducing the overall width of the vehicle and facilitating the transport of balls to the golf washing room via a walkway. The golf retrieval vehicle also features a rolling brush at the front. As the vehicle moves forward, the rolling brush sweeps balls within the front wheel area towards the ball-retrieval devices on both sides, preventing them from being crushed into the soil and improving retrieval efficiency.

[0034] In this embodiment, ball-collecting mechanisms 2 are provided on both sides of the vehicle frame 1 to collect the balls on both sides. Two ball-collecting mechanisms 2 are designed to increase the working width of the ball-collecting operation. They are mounted on a lifting and rotating deployment mechanism 3. During vehicle transport, the ball-collecting mechanisms 2 first rise, lifting off the ground, then rotate 90 degrees and retract to fit snugly against the vehicle's exterior wall, thereby reducing the overall width of the vehicle. This not only provides better maneuverability but also effectively prevents the ball-collecting mechanisms from colliding with other vehicles or exterior walls, increasing driving safety.

[0035] During ball retrieval, the control unfolding mechanism 3 rotates the ball retrieval mechanism 2 90 degrees to open it to both sides, then places it on the ground, switching to working mode to clamp and pick up the balls on the ground. The ball retrieval mechanism 2 then transports the balls to the conveyor assembly 5 at the bottom of the frame 1. After the balls are fed into the conveyor assembly 5, they are conveyed to the spiral feeding mechanism 7. Cleaning components 6 are installed on both the upper and lower belt surfaces of the conveyor assembly 5. When the balls pass through, they are driven by the differentially rotating brushes to obtain rotational power, thereby better cleaning the weeds, sand, and other debris adhering to the balls and transporting them to the ball storage box 8. After the ball storage box 8 is full, the vehicle can drive directly to the ball washing room to unload the balls, optimizing the transfer process and facilitating subsequent cleaning.

[0036] The outer side and top of the frame 1 are provided with protective brackets 11. The ball sweeping assembly 4 is installed on the protective brackets 11 and the frame 1. The ball sweeping assembly 4 includes a support frame 12. A telescopic rod 13 is vertically arranged on the support frame 12. A mounting plate 14 is provided at the output end of the telescopic rod 13, which drives the mounting plate 14 to reciprocate in the vertical direction.

[0037] In this embodiment, the ball sweeping assembly 4 is located at the front end of the frame. The support frame 12 is bolted to the frame 1 and the protective bracket 11. A limiting rod is provided above the support frame 12 to limit the position of the support frame 12. During the ball sweeping process, the support frame 12 rotates. The telescopic rod 13 is an electric telescopic rod, which is set at the end face of the support frame 12. The output end faces downward and is connected to the mounting plate 14 to control the setting height of the mounting plate 14.

[0038] Mounting plate 14 is located in front of the front wheel. A ball sweeping assembly 4 is provided on mounting plate 14. The ball sweeping assembly 4 includes at least two ball sweeping brushes 41. The two ball sweeping brushes 41 rotate in opposite directions, so that the ball moves from both sides of the front wheel to the ball picking mechanism 2, so that the front wheel will not run over the ball. The ball picking mechanism 2 is located in front of the two rear wheels to pick up the ball on the ground and ensure driving safety.

[0039] The unfolding mechanism 3 is located above the input end of the conveying component 5. The unfolding mechanism 3 includes a first base 31, with tilting arms 32 on both sides of the first base 31. A lead screw 311 is provided at the bottom of the first base 31, with a lead screw nut 312 fitted on the lead screw 311. A connecting arm 313 is installed above the lead screw nut 312. The lead screw 311 is rotated by a motor, which in turn drives the connecting arm 313 to move. One side of the connecting arm 313 is connected to the tilting arm 32. Guide rails and sliders are provided between the two sides of the tilting arm 32 and the first base 31, so that the tilting arm 32 reciprocates in the vertical direction, driving the ball picking mechanism 2 to move.

[0040] In this embodiment, the first base 31 is mounted on the protective bracket 11. A synchronous pulley is located at the bottom of the first base 31. Bearing seats are located on both sides of the driven pulley of the synchronous pulley, respectively connecting to lead screws 311. A lead screw nut 312 is fitted onto the outside of the lead screw 311. A connecting arm 313 is rotatably mounted above the lead screw nut 312. The first base 31 also has several rope limiters. One end of the connecting arm 313 is connected to a traction rope (not shown in the figure). The traction rope is connected to the first connecting rod 322 of the tilting boom 32 via the rope limiters. The connecting arm 313 and the second base 321 are rotatably connected. When the lead screw 311 rotates, the connecting arm 313 moves and tilts accordingly, tightening or loosening the traction rope and assisting the rotating boom 32 to rotate, thereby achieving a 90° rotation of the ball-collecting mechanism 2. The second base 321 of the rotating boom 32 is connected to the first base 31 through a guide rail and a slider. If the ground is uneven during vehicle travel, the ball-collecting mechanism 2 on one or both sides can automatically rise and fall, and tilt by rotating the boom 32, making it more suitable for different terrains of the court.

[0041] The tilting boom 32 includes a second base 321. A first connecting rod 322 and a second connecting rod 323 are arranged above the second base 321. The first connecting rod 322 and the second connecting rod 323 are sequentially connected to both sides of the electric telescopic rod. They rotate about the connection point of the second base 321 as the center, driving the electric telescopic rod to move. The output end of the electric telescopic rod is connected to the ball-collecting mechanism 2, which switches the ball-collecting mechanism 2 between the storage state and the working state. The height of the ball-collecting mechanism 2 from the ground is adjusted by the electric telescopic rod.

[0042] In this embodiment, there are two first connecting rods 322 and second connecting rods 323, which are rotatably connected to four positions on the front and rear sides of the electric telescopic rod. A crossbeam is installed between the two first connecting rods 322 for connecting the traction rope. The electric telescopic rod is moved by the first connecting rods 322 and second connecting rods 323, which changes the output direction of the electric telescopic rod and realizes the angle rotation of the ball picking mechanism 2, switching between the storage state and the working state.

[0043] The ball-collecting mechanism 2 includes a third base 21. A limit baffle 22 is provided on the top of the third base 21 to prevent collision with the second base 321. The third base 21 is provided with ball-collecting fins 23. Ball-removing plates are provided at the intervals of the ball-collecting fins 23. A spiral guide rod 24 is provided on the side of the ball-collecting fins 23 near the front end of the frame 1. A volume cavity is formed between the spiral guide rod 24 and the third base 21. After the ball is collected by the ball-collecting fins 23, it is transported into the volume cavity through the ball-removing plates and then transported through the spiral guide rod 24. An output port 211 is provided on the side of the third base 21 near the frame 1. The output port 211 is located above the cleaning component 6 and transports the collected ball to the cleaning component 6 for cleaning.

[0044] In this embodiment, a ball-collecting fin 23 is installed on the third base 21. In the working state, the ball-collecting fin 23 is in contact with the ground, and several ball-collecting fins 234 are arranged to clamp and rotate the ball for transport. A ball-retrieving plate is provided above the ball-collecting fin 23. Several racks are provided on the ball-retrieving plate, which extend into the gap of the ball-collecting fin 23 to separate the clamped ball from the ball-collecting fin 23 and drop it into the volume cavity formed by the threaded guide rod 24 and the third base 21. The threaded guide rod 24 is rotated by the motor to transport the collected balls sequentially towards the output port 211, so that the balls fall from the output port 211 into the transport assembly 5.

[0045] The conveying assembly 5 includes a conveying frame 51, on which a chain rod and chain assembly 52 is mounted. The chain rod and chain assembly 52 cooperates with a sprocket. The chain rod and chain assembly 52 is driven to rotate by a motor to convey the ball. The cleaning assembly 6 includes a first brush assembly 61 and a second brush assembly 62, which are connected to a motor for rotational cleaning. The first brush assembly 61 is located below the chain rod and chain assembly 52, and the second brush assembly 62 is located above the chain rod and chain assembly 52. ​​The ball is cleaned by the first brush assembly 61 and the second brush assembly 62.

[0046] In this embodiment, the chain rod assembly 52 has two chains, with several chain rods between them. The gap between the chain rods is smaller than the diameter of the ball. The ball falls between the two chain rods and is driven by a motor to rotate the sprocket, which in turn drives the chain rod assembly 52 to rotate, thus conveying the ball. A first brush assembly 61 is provided on the inner side of the chain rod assembly 52, and a second brush assembly 62 is provided above the chain rod assembly 52. ​​Both the first brush assembly 61 and the second brush assembly 62 are configured as two roller brushes to clean the ball. The second brush assembly 62 rotates faster than the first brush assembly 61. When the ball passes through, it gains rotational power under the differential rotation of the brushes, thereby better cleaning off weeds, sand, and other debris adhering to the ball before it is conveyed to the ball storage box 8.

[0047] The cleaning component 6 conveys the ball to the spiral feeding mechanism 7. The spiral feeding mechanism 7 includes a housing 71. A turntable 72 is provided at the bottom of the inner side of the housing 71, which drives the ball to rotate inside the housing. Pipes are connected to the curved wall of the housing 71 to convey the ball to the ball storage box 8.

[0048] In this embodiment, the shell 71 is circular, and a turntable 72 is provided at the bottom of the inner side. The turntable 72 is driven by a motor to rotate. After the ball enters the inner side of the shell 71, it is accelerated by the turntable 72 and makes a circular motion inside the shell 71. Under the action of centrifugal force, it contacts the inner wall of the shell 71 and moves to the interface of the pipe. The pipe interface is set along the tangent of the inner wall and is transported to the ball storage tank 8. Furthermore, the turntable 72 is inclined and the inner wall of the shell 71 is provided with a spiral track. After the ball falls in, it moves to the lowest point of the turntable 72 and is driven by the turntable 72 to move into the pipe along the inner wall of the shell 72.

[0049] A fan 9 is installed on the protective bracket 11. The fan 9 is connected to the ball storage box 8 through a pipe, so that the inner cavity of the ball storage box 8 is under negative pressure. The ball storage box 8 is connected to the spiral feeding mechanism 7 through a pipeline, which sucks the balls into the ball storage box 8.

[0050] In this embodiment, the ball and the pipe are fitted with a small clearance. The force provided by the spiral feeding mechanism 7 and the suction provided by the negative pressure cavity of the ball storage tank 8 cause the ball to move inside the pipe and fall into the ball storage tank 8. This application uses a large-capacity ball storage tank 8, which can hold up to 10,000 balls. A level gauge is installed inside the ball storage tank 8 to monitor the remaining capacity of the tank at any time. After the tank is full, the vehicle can drive directly to the ball washing room to unload the balls, which optimizes the transfer process and facilitates subsequent cleaning.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
