EMBODIMENT OF THE INVENTION Hereinafter, a golf ball recovery device according to an embodiment of the present invention will be described in detail with reference to the drawings. In addition, in the figure, the direction in which the collection body advances is referred to as the front-rear direction, the width direction of the pond that is orthogonal to the front-rear direction is referred to as the left-right direction, and the direction orthogonal to the front-rear direction and the left-right direction is referred to as the up-down direction. The following description will be made using this direction as a reference.

(Embodiment 1)
The golf ball recovery device according to the first embodiment of the present invention is used in conjunction with a pond installed at a golf driving range, and the pond also has a structure suitable for recovering golf balls.

Having a pond at a golf practice range has various benefits. For golfers, having a pond on the fairway has the advantage that distance and direction can be immediately determined compared to when there is no pond on the fairway. In addition, the pond is a penalty area where penalties are imposed, and the presence of the pond increases the seriousness of golfers. In addition, the presence of a pond provides golfers with a sense of the seasons, providing coolness in the hot summer and the shine of the water surface in the spring and fall when the sun is low.

In order to recover golf balls that have fallen into a pond at a golf driving range, the bottom surface of the pond may be sloped from the outer periphery toward the center, and the golf balls may be moved along this slope to be recovered. However, when forming a pond with a sloped bottom surface, it is necessary to cut out the soil corresponding to the slope, which means that a large amount of soil is cut out, resulting in an unbalanced balance between cutting and filling. Also, because the water depth at the bottom changes, it is difficult to correct the subsidence of the fairway.

The pond used in this embodiment has a horizontal bottom surface and a shallow water depth. Therefore, there is a good balance between cutting and embankment, making it easier to work on fairway ground subsidence. Since the water depth is shallow and there is little cutting and filling, it is possible to form a large pond with a long depth. Furthermore, by forming a pond with a long depth, the golfer can visually check the entire water surface of the pond from the batting area.

Furthermore, by forming a large pond with a long depth, the area for laying artificial turf is reduced, and the labor for managing the artificial turf is reduced. Furthermore, by reducing the area where artificial turf is laid, the cost of replacing artificial turf can be reduced, and the cost of disposing of old artificial turf as industrial waste can also be saved.

(Structure of pond)
First, the structure of the pond used in this embodiment will be explained with reference to FIG. As shown in FIG. 1, the pond 1 is formed into a rectangle when viewed from above. Note that pond 1 is shown without water. The pond used in this embodiment is, for example, 15 m wide, 50 m deep, and 0.25 m deep. The pond 1 includes a bottom 2, a pair of side walls 3 vertically rising from the left and right ends of the bottom 2, and a pair of inclined walls 4 rising obliquely from the front and rear ends of the bottom 2.

The bottom portion 2 is formed of a horizontal surface without an inclination. A first ball collecting groove 5a extending in the left-right direction along the inclined wall 4 is formed at the rear end of the bottom part 2, and a second ball collecting groove 5a extending in the left-right direction along the inclined wall 4 is formed in the front end of the bottom part 2. A ball collecting groove 5b is formed, and a third ball collecting groove 5c extending in the left-right direction is formed between the first ball collecting groove 5a and the second ball collecting groove 5b. The first ball collecting groove 5a, the second ball collecting groove 5b, and the third ball collecting groove 5c are inclined downward from the right to the left in the figure. 2(a) is a cross-sectional view taken along line AA in FIG. 1, and FIG. 2(b) is a cross-sectional view taken along line BB in FIG. From FIGS. 2(a) and 2(b), it can be confirmed that the first ball collecting groove 5a and the second ball collecting groove 5b are inclined. Due to this slope, the golf ball that falls into the first ball collecting groove 5a and the second ball collecting groove 5b moves from right to left. The third ball collecting groove 5c also has a similar structure. At the left end portions of the first ball collecting groove 5a, the second ball collecting groove 5b, and the third ball collecting groove 5c, the golf ball that has reached the left end portion is lifted by air in water and transferred as described below. A ball lifting device 7 for moving the ball into the groove 6 is provided.

As shown in FIG. 1, the bottom portion 2 is provided with a transfer groove 6 extending in the front-rear direction along the left side wall 3. The golf balls that have reached the left ends of the first ball collecting groove 5a, the second ball collecting groove 5b, and the third ball collecting groove 5c are moved into the transfer groove 6 by the ball lifting device 7 shown in FIG. and falls. As shown in FIGS. 2(a) and 2(b), the depth x2 on the front side of the transfer groove 6 is deeper than the depth x1 on the rear side of the bottom part 2, and the transfer groove 6 is directed from the back of the bottom part 2 to the front. It is tilted downward. Therefore, the golf ball that has entered the transfer groove 6 moves from the back to the front inside the transfer groove 6, and is sent to the water-ball separator installed at the tip of the arrow in FIG.

A first pit 8 is provided behind the rear inclined wall 4 and forms a space used for routing a wire rope led out from an endless winch, which will be described later. A through hole 8a is formed in the inclined wall 4 for introducing a wire rope into the pond 1 from the first pit 8.

Behind the right side wall 3, a second pit 9 is formed, which is a space for accommodating a submersible pump or valve, and behind the left side wall 3, a drive device for driving the ball lifting device 7 is formed. A third pit 10 is formed as a space for storage.

(Overall configuration of golf ball recovery device)
Next, the overall configuration of the golf ball recovery device will be described with reference to FIG. 3. Although the structure of the pond 1 is also part of the golf hole recovery device, structures other than the structure of the pond 1 will be explained here. Note that the third ball collecting groove 5c is not shown in FIG. The golf ball recovery device 100 includes a recovery body 110 that moves inside the pond 1, a drive unit 200 that moves the recovery body 110 inside the pond 1, and a position sensor 240.

The collection main body 110 includes a frame main body 111, a ball prevention net 112, wheels 113, side rollers 114, and a collection section 116, similar to the collection main body 110 described in the first embodiment. The recovery main body 110 of this embodiment is different from the first embodiment in that it does not include the wire rope fixing part 115, the wire rope guide tube 117, and the guide sheave 118, but includes a guide sheave 119 around which the wire rope 230 is wound. do. Descriptions of members having the same structure will be omitted. The guide sheave 119 includes a pair of front guide sheaves 119a that guide the wire rope 230 from the second single-hull winch 250b to the front fixing fitting 14 inside the collection body 110, and a pair of front guide sheaves 119a that guide the wire rope 230 from the first single-hull winch 250a to the rear side. and a rear guide sheave 119b that guides the wire rope 230 to the fixing fitting 14 inside the collection main body 110.

When it is desired to move the recovery main body 110 forward, the second single-barrel winch 250b rotates the wire rope 230 in the winding direction, and the first monobarrel winch 250a rotates the wire rope 230 in the direction of releasing it (winding direction). (in the opposite direction). When it is desired to move the recovery main body 110 backward, the second single-body winch 250b rotates in a direction to release the wire rope 230, and the first single-body winch 250a rotates in a direction to wind up the wire rope 230. let The position of the collecting body 110 is detected by a position sensor (not shown) provided in front of the first ball collecting groove 5a and the second ball collecting groove 5b, and It will be stopped in front of.

Next, a method for collecting golf balls using the golf ball collecting apparatus 100 of this embodiment will be described. Specifically, a method for collecting golf balls will be described with reference to FIGS. 8 and 9(a).

The rope 230 moves and the collection body 110 moves forward. As the collection main body 110 moves forward, the golf balls accumulated on the bottom 2 of the pond 1 are pushed by the collection section 116 of the collection main body 110 and are moved forward. Then, as shown in FIG. 9(a), the golf ball moved by the collection main body 110 falls into the second ball collecting groove 5b.

When the first mono-barrel winch 250a is rotated in the winding direction and the second mono-barrel winch 250b is rotated in the releasing direction, the wire rope 230 moves in the opposite direction to the direction of the arrow shown in FIG. The collection main body 110 moves backward. As the collection main body 110 moves backward, the golf balls accumulated on the bottom 2 of the pond 1 are pushed by the collection section 116 of the collection main body 110 and are moved backward. The golf ball moved by the collection body 110 falls into the first ball collecting groove 5a. The golf balls that have fallen into the first ball collecting groove 5a and the second ball collecting groove 5b move inside the respective ball collecting grooves from right to left, are then moved to the transfer groove 6, and are further transferred to the water It is transported to the sphere separator.

According to the present embodiment, since the collection body 110 is moved using two single-body winches 250, the collection body 110 can be moved with a smaller force than when using the endless winch 210. Furthermore, the wire rope 230 is easier to maneuver than using the endless winch 210. Further, since the two single-barrel winches 250 rotate in opposite directions to each other in the winding direction and the opening direction, it is recommended to use them in small ponds in consideration of irregular winding conditions.

(Modified example)
In the second embodiment, it has been explained that one collection main body 110 is moved by the single body winch 250, but similarly to the modification of the endless winch 210, two collection main bodies 110 can also be used. The structure other than the single-hull winch 250 is the same as that of the second embodiment, so the details will be omitted.

In a modified example, a case where golf balls are collected will be explained based on FIG. 9(b) and FIG. 10. At the initial position, the collection main body 110a is arranged near the third ball collecting groove 5c, and the collecting main body 110b is arranged near the first ball collecting groove 5a, as shown in FIGS. 9(b) and 10. . In this state, the second single body winch 250b rotates in the direction to wind up the wire rope 230, and the first single body winch 250a rotates in the direction to release the wire rope 230. The wire rope 230 moves in the direction shown by the arrow in FIG. 10, and moves the collection main bodies 110a and 110b forward. When moving the collection bodies 110a and 110b backward, the second single-barrel winch 250b moves in the direction of releasing the wire rope 230, and the first single-barrel winch 250a moves in the direction of winding the wire rope 230. Rotate. Through these operations, the collection main body 110a and the collection main body 110b move forward or backward, and the golf balls that have fallen into the first area 2a fall into the second ball collecting groove 5b and the third ball collecting groove 5c, and the golf balls that have fallen into the first area 2a fall into the second ball collecting groove 5b and the third ball collecting groove 5c. The golf ball that has fallen into the area 2b falls into the first ball collecting groove 5a and the fourth ball collecting groove 5d. The golf ball is then moved to the transfer groove 6 and then transported to the water-ball separator.

Spin and get up. The lower end of the collection unit 130 approaches the bottom 2 of the pond 1 by rising, so it is in a state to collect golf balls. When the recovery unit 130 moves backward, the recovery unit 130 is pulled by the wire rope 230 attached to the rear wire rope fixing unit 115, so the recovery unit 130 uses the connecting pin 131d as a fulcrum, as shown in FIG. 14(a). It rotates in the direction of the arrow shown in FIG. 14(b), and is in an inclined state. The lower end of the collecting section 130 is tilted away from the bottom 2 of the pond 1, so that golf balls are not collected.

The recovery unit 130 is connected to the auxiliary frame 140 by a traction swing lever 150. By pulling the wire rope 230, the diagonal member 142 is also moved forward via the traction lever 146, and the lever connecting pipe 141 connected to the diagonal member 142 is also pulled forward. Due to this tensile force, the rocking plate auxiliary member 131b also rises via the traction rocking lever 150 and the rocking plate connecting pipe 132. In this way, by providing the auxiliary frame 140, by pulling the front wire rope 230, the swing plate 131 of the recovery unit 130 can be raised with a small force.

The protective net 135 used in this embodiment is attached only to the front surface of the collection body 120. This is not a protective net that covers the entire collection body 110 like the protective net used in the first and second embodiments. In this embodiment, the collection main body 120 collects golf balls only when moving forward, and does not collect golf balls when moving backward, so there is no need to protect the entire body with a protective net.

A golf ball recovery method using the movable recovery body 120 will be explained using FIGS. 11-14 and 16. At the initial position, the collection main body 120 is located at the rear end in FIG. In this state, the endless winch 210 is driven to pull the front wire rope 230 in the direction of the arrow, and the recovery main body 120 is moved forward. When the collection main body 120 moves forward, the collection unit 130 is pulled by the auxiliary frame 140 and rises, as shown in FIGS. 14(a) and 16. In this state, when the collection main body 120 is advanced as shown in FIGS. 11 and 13, the collection main body 120 contacts the golf ball and moves the golf ball forward. When the collection main body 120 arrives in front of the ball collecting groove 5e, its position is detected by a position sensor (not shown) and the collection body 120 stops. The golf balls moved by the collection body 120 fall into the ball collection groove 5e, and the fallen golf balls move from right to left in the ball collection groove 5e, and are then transported to the water-ball separator. Ru.

When the golf ball collection is completed, the endless winch 210 rotates in the opposite direction to move the collection main body 120 backward. As shown in FIGS. 12 and 14(b), the recovery section 130 is not pulled by the front wire rope 230, but the rear wire rope 230 is pulled, so the recovery section 130 is in an inclined state, and the recovery section 130 is in an inclined state. Move backward while leaving a space between you and the bottom 2. Therefore, when going backwards, the golf balls are not collected.

According to this embodiment, by using the movable collecting section 130, golf balls are collected only when the collecting main body 120 moves forward, so one ball collecting groove 5e is provided at the front end. to collect the golf ball. Therefore, only one ball collecting groove is required, and unlike the case where a plurality of ball collecting grooves are provided, there is no need to provide the transfer groove 6. Therefore, the structure of the pond 1 is simplified, construction is easier, and costs are also reduced.

The slide portion 521 is arranged between the recess 512 and the pipe portion 522, and includes a slide rod 521a and a rotation prevention portion 521b. The slide rod 521a is made of stainless steel or the like, and one end of the slide rod 521a is inserted into the pipe portion 522, and the other end is inserted into a slide pipe fitting described later. The slide rod 521a includes two parts: a first part 521aa that is inserted into the pipe section 522, and a second part 521ab that is inserted into the slide pipe fitting. In this embodiment, the outer diameter of the first portion 521aa inserted into the pipe portion 522 of the slide rod 521a is 40 mm, and the outer diameter of the second portion 521ab inserted into the slide pipe fitting is 30 mm. It is. The inner diameter of the pipe portion 522 is 40 mm.

The slide rod 521a and the pipe portion 522 are fixed via a joint piece 521d. As shown in FIGS. 18(a) to 18(c), the joint piece 521d includes a pair of plates that sandwich the outside of the pipe portion 522 from left and right, and the inside of the pair of plates matches the external dimensions of the pipe portion 522. It is formed like this. A first portion 521aa of the slide rod 521a is inserted into the pipe portion 522 sandwiched between the joint pieces 521d. Bolt holes are formed in each of the joint piece 521d, the pipe portion 522, and the first portion 521aa of the slide rod 521a.The bolt holes are aligned and the bolts 521c are inserted into these bolt holes. By fastening them together, the joint piece 521d, the pipe portion 522, and the slide rod 521a are fixed. By fixing the joint piece 521d, the pipe portion 522, and the slide rod 521a, the joint piece 521d forms a rectangular parallelepiped outer shape.

The sheave bracket 532 is a member that protects the sheave 531 and attaches the sheave 531 to the inner peripheral surface of the second pond 310 with an anchor bolt 532a. The combination of sheave 531 and sheave bracket 532 is attached to the inner peripheral surface of second pond 310 at a predetermined interval.

When the wire rope 504 is pulled by the endless winch 503, the plate guide 523b is guided by the guide plate 533, and the recovery unit 520 moves inside the second pond 310.

In this embodiment, a method for collecting golf balls in the second pond 310 will be described. The second collection main body 500 moves from the first position indicated by the dotted line on the right side of FIG. 17 to the second position indicated by the dotted line on the left side. In the first position and the second position, the second recovery main body 500 is in a state of being inserted into the lower part of the slope of the green 400. The second recovery main body 500 is placed at the first position in the initial position. Then, by pulling the wire rope 504 in the direction of the arrow by the endless winch 503, the recovery section 520 to which the wire rope 504 is connected rotates clockwise.

At this time, the guide plate 533 of the guide section 530 enters between the plate guide 523b at the tip of the collecting section 520 and the wire rope 504, the plate guide 523b is guided by the guide plate 533, and the collecting section 520 moves. The presence of the slide portion 521 allows the pipe portion 522 to slide in the radial direction, and can absorb changes in length due to distortion of the collection portion 520 in the radial direction.

By rotating the collecting section 520 clockwise to the dotted line position on the left side of the second pond 310, the golf balls that have fallen to the bottom 501 of the second pond 310 are moved clockwise by the pipe section 522. When the collection unit 520 moves to the position shown by the dotted line on the left side, the position is detected by a position sensor (not shown), and the movement of the collection unit 520 is stopped. The golf ball is moved clockwise by the collecting section 520, falls into the ball collection groove 540, and is collected. After a predetermined period of time has elapsed, the endless winch 503 is rotated in the opposite direction to rotate the collecting section 520 counterclockwise to collect the golf ball again.

According to this embodiment, by providing the second recovery body 500 in the circular second pond 310, golf balls can be efficiently recovered even in the circular pond. Furthermore, since a method is adopted in which the tip of the collection unit 520 is driven, the collection device can be installed even when the radius of the pond is large.

(Modified example)
In the present embodiment, it has been explained that the recovery unit 520 moves the rope guide 523a by pulling the wire rope 504 and is guided by the plate guide 523b by the guide plate 533, but other methods may also be adopted. good.

As shown in FIG. 20, the engaging section 523 of the collecting section 520 uses a guide roller 523c and a rope guide 523d instead of the rope guide 523a and plate guide 523b. Further, a guide rail 534 is used instead of the guide plate 533 of the guide portion 530.

The guide roller 523c is attached to the tip of the pipe portion 522, and includes a pair of wheels 523cc provided with both ribs. The axis of the wheel 523cc is arranged parallel to the axis of the pipe portion 522, and the cylindrical portion between the brim of the wheel 523cc contacts the guide rail 534. Further, a rope guide 523d to which an end of the wire rope 504 is connected is attached to the opposite side of the guide roller 523c to the side to which the pipe portion 522 is attached.

The wire rope 504 is stretched along the inner surface of the side wall 502 of the second pond 310 and is moved by the endless winch 503. A plurality of sheaves 531 are attached to the side wall 502 at predetermined intervals, and each sheave 531 is housed in a sheave bracket 532. The number of sheaves 531 is determined depending on the size of second pond 310, but in this embodiment, 25 to 30 sheaves 531 are attached to side wall 502. Wire ropes 504 are arranged above and below the plurality of sheaves 531, and movement of the wire ropes 504 is regulated by the sheaves 531. The rope guide 523d is connected to the wire rope 504 passing under the sheave 531.

As the endless winch 503 rotates, the wire rope 504 is moved to the right or left (clockwise or counterclockwise) in the drawing, and as the wire rope 504 moves, the rope guide connected to the wire rope 504 moves. Guide roller 523c moves on guide rail 534 via 523d. By moving the guide roller 523c, the pipe portion 522 is moved, and the golf ball falling into the second pond 310 is moved clockwise or counterclockwise. The moved golf balls fall into the ball collecting groove 540 and are collected.

(Modified example of ball lifting device)
In Embodiment 1-4, the golf ball is lifted by air in the water by the ball lifting device 7 and moved to the transfer groove 6, but other types of ball lifting devices may be used. An example of a ball lifting device using a radial gate is shown in FIG. 21, and an example of a ball lifting device using a flap gate is shown in FIG.

FIG. 21 shows a ball-lifting device using a radial gate. FIG. 21(a) is a top view of the ball-lifting device, (b) is a side view, and (c) shows the frame gate from the Y1 direction of (b). This is the view. As shown in FIG. 21, the ball lifting device 600 includes a gate section 610 and a drive section 620.

The gate section 610 includes a gate frame 612 and a door body 613. The gate frame 612 accommodates the door body 613 and has an outer shape that is one size larger than the door body 613. The door body 613 is a plate material with a curved shape, and prevents water in the first ball collecting groove 5a (the same applies to the second ball collecting groove 5b, the third ball collecting groove 5c, and the fourth ball collecting groove 5d). The plate surface is arranged perpendicular to the flow of water, and rotates around a rotation axis 613a. The door body 613 functions as a gate that opens and closes the water channel of the first ball collecting groove 5a by rotating around the rotating shaft 613a. A wire rope 625 is connected to the upper part of the door body 613, and the wire rope 625 is connected to the drive part 620 via a sheave 611 provided at the upper part of the gate part 610.

The drive unit 620 includes a solenoid valve 622, a weight box 623, and a guide frame 624. The solenoid valve 622 is a valve that opens and closes a supply pipe 622a that supplies water to the heavyweight box 623. When the electromagnetic valve 622 is opened, water flows through the supply pipe 622a, and the water is supplied to the weight box 623 from the water supply port 622b. The heavyweight box 623 is a box that stores water, and a wire rope 625 is connected to the top. The guide frame 624 is a frame that is disposed outside the corner of the weight box 623 and guides the weight box 623 in the vertical direction. When water is supplied to the heavyweight box 623 from the water supply port 622b, the heavyweight box 623 is guided by the guide frame 624 due to the weight of the water and descends. A drain port 623a is formed in the heavy duty box 623, and the amount of water supplied from the water supply port 622b is greater than the amount of water discharged from the drain port 623a, so the difference between the supplied amount and the discharge amount is accumulated in the heavy weight box 623. It turns out. When the heavyweight box 623 descends, the wire rope 625 is pulled, the door body 613 opens, and the golf balls are collected. When the golf ball collection is completed, the electromagnetic valve 622 is closed and the supply of water from the water supply port 622a is stopped. Since the drain port 623a at the bottom of the heavy weight box 623 is always open, water accumulated in the heavy weight box 623 flows from the drain port 623a, and the center of gravity box 623 rises.

A method of using the ball lifting device 600 of this modification will be explained. When the user determines that a certain amount of golf balls have accumulated in the first ball collection groove 5a, the user opens the solenoid valve 622 to supply water to the heavyweight box 623. The heavy box 623 descends due to the weight of the water, and the wire rope 625 is pulled downward. The wire rope 625 connected to the door body 613 is pulled upward, and the door body 613 rotates around the rotation axis 613a. Since the door body 613 moves to open the gate, the golf balls accumulated in the first ball collection groove 5a move to the transfer groove 6. After a predetermined period of time has elapsed, the solenoid valve 622 is closed, the weight box 623 is raised, and the gate is closed.

FIG. 22 shows a ball-lifting device using a flap gate. FIG. 22(a) is a top view of the ball-lifting device, (b) is a side view, and (c) is a frame gate viewed from the Y2 direction of (b). This is the view. As shown in FIG. 22, the ball lifting device 700 includes a gate section 710 and a drive section 720.

The gate portion 710 includes an angled lever 711, a flap gate 712, and a gate frame 713 that accommodates the flap gate 712 therein. The angled lever 711 has a peak connected to a bearing of a bearing stand 711a. One end of the angled lever 711 is connected to one end of a connecting bar 724, which will be described later, and the other end is connected to a bearing of a bearing stand 711a, and connected to the flap gate 712 via a connecting pin 711b. The flap gate 712 is a gate that opens and closes the first ball collecting groove 5a. The angled lever 711 and the flap gate 712 are formed into a bent mountain shape when viewed from the side, and the tops of the mountain are connected by a connecting pin 711b, and move in the direction of the arrow around the connecting pin 711b. When the angled lever 711 is rotated counterclockwise by the connecting bar 724 about the connecting pin 711b, the flap gate 712 opens, and when the angled lever 711 is rotated clockwise, the flap gate 712 closes.

The drive unit 720 includes a deceleration motor 722, a motor pedestal 722a on which the deceleration motor 722 is mounted, a circular rotary plate 723 attached to the deceleration motor 722, a limit switch 721, and a connection bar 724.

The rotational center of a circular rotary plate 723 is connected to the rotary shaft of the deceleration motor 722, and the rotary plate 723 is rotated clockwise or counterclockwise by the deceleration motor 722. The connection bar 724 is formed in a U-shape, and one end of the U-shaped connection bar is connected to the outer periphery of the circular plate of the rotating plate 723, and the other end is connected to the angled lever 711. The connection bar 724 swings in the left-right direction as the rotating plate 723 rotates. Two limit switches 721 are arranged on the outside of the rotating plate 723, and when the connecting bar 724 comes into contact with them, the fully open position and the fully closed position of the gate are detected.

A method of using the ball lifting device 700 of this modification will be explained. When the user determines that a certain amount of golf balls have accumulated in the first ball collection groove 5a, the user drives the deceleration motor 722. When the flap gate 712 is closed, the angled lever 711 tilts to the right as shown by the solid line, the connecting bar 724 contacts the right limit switch 721, and the rotation of the deceleration motor 722 is stopped. . When the deceleration motor 722 is driven in this state and the rotating plate 723 rotates counterclockwise, the connecting bar 724 swings to the left, causing the angled lever 711 to tilt to the left. Then, the flap gate 712 rotates upward around the connecting pin 711b to open the gate. When the rotary plate 723 rotates 180 degrees from the closed state of the flap gate 712, it comes into contact with the left limit switch 721, so that the rotation of the deceleration motor 722 is stopped. By opening the flap gate 712, the golf balls accumulated in the first ball collection groove 5a move to the transfer groove 6.

According to this modification, by using the gate, golf balls can be easily collected with a simple structure.

In Embodiment 1-4, a golf ball recovery device installed in a pond at a golf driving range has been described. The golf ball recovery device according to the present invention can be installed not only in a pond at a golf driving range but also in a pond at an original golf course.

In Embodiment 1-4, a photoelectric sensor is used as the position sensor 240, but means for increasing the sensitivity of the photoelectric sensor may be added. A light emitter and a light receiver may be installed on the side wall 3 of the pond 1 at a position higher than the water surface, and an antenna extending upward may be installed on the recovery body 110 to detect whether the light from the light emitter is blocked by the antenna.

In Embodiment 1-4, a photoelectric sensor is used as the position sensor 240, but a mechanical sensor may also be used.
