Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf driving range ball collecting device for collecting balls from a pond provided in a driving range.

[0002]

2. Description of the Related Art In order to improve the view of the open space of a golf driving range, it is desired to install a pond in the open space. However, when a pond is set up in the open space, it is not easy to collect golf practice holes that jump into the pond. The following methods and devices are conventionally known as methods or devices for collecting balls from a pond provided in a golf driving range.

For example, (1) a device for attaching a collecting net to the bottom of the pond and lifting the net to collect the balls that have sunk in the pond; (2) draining all the water from the pond to the bottom of the pond. A method for the worker to collect the balls remaining in the pond, (3) A method for the worker to pick up the balls in the pond with a net, and (4) install an underwater conveyor in the pond and operate this conveyor automatically It is a device to scoop the ball in the pond outside the pond.

[0004]

However, in the ball collecting device of the above (1), the ball collecting work cannot be performed without pulling up the net for collecting balls, but it is not preferable in view of the scenery to pull up the net during business hours. For this reason, the balls will be collected when the business is closed, such as after the business is closed, and the practice ball usage efficiency (rotation efficiency) will be low, so the practice field manager must prepare a large number of practice balls for business. I have to.

Also in the above method (2), draining the water of the pond during business hours is not preferable in view of the scenery. For this reason, there is no choice but to collect the balls when the business is closed. Therefore, as in the case of (1) above, the practice ball is less efficiently used. In addition, there is a problem that equipment for temporarily storing discharged water is required in an area where water resources are scarce and the equipment becomes large.

Further, the above method (3) requires a great deal of labor, so the work efficiency is very poor, and the recovery work during business hours is difficult from the viewpoint of ensuring the safety of workers. Further, in the device of the above (4), since a mechanical structure such as an underwater conveyor is installed underwater, there is a problem that breakdown is likely to occur and maintenance is not easy, and that the device equipment becomes large. There is.

Therefore, an object of the present invention is to provide a ball collecting device for a golf practice range which can easily collect practice balls even during business hours.

[0008]

In order to achieve the above object, in a golf driving range ball collecting apparatus according to the present invention, a water flow is generated at the bottom of the pond toward the deepest part of the pond,
Water flow generation means that guides the ball sinking in the pond to the deepest part of the pond,
The structure is provided with a spraying means for spraying a ball from the deepest part of the pond above the water surface of the pond, and a receiving means for receiving the sprayed ball above the water surface of the pond and guiding it to the ball recovery path.

[0009]

According to the present invention, the practice balls that have entered the pond are collected at the deepest part of the pond by the water flow generator, and then blown up above the water surface by the blowing means and above the water surface by the receiving means. It is received and introduced to the ball collection path.

[0010]

Embodiments of the present invention will be described below with reference to FIGS.
This will be described with reference to 2. FIG. 1 is a plan view of a golf driving range in which a ball collecting device according to the present invention is installed. As shown in FIG. 1, the present invention is applied to a golf driving range where a pond 2 is provided in a practice space 1 for leaving a practice ball.

One of the open spaces 1 faces the practice bat 3 and is surrounded on three sides by a ball-proof net 5. Practice at bat 3
Alternatively, the ball lending machine installed in the vicinity of the ball lending machine is supplied with practice balls collected from the space 1 through the ball storage line 6 through the ball supply line 7. A ball collection path 8 is installed between the pond 2 and the ball storage room 6, and the practice ball pulled up from the pond by the ball collection device according to the present invention is guided to the ball storage room 6 through the ball collection path 8. .

FIG. 2 is a plan view of a pond in which balls are collected by the ball collecting device according to the present invention, FIG. 3 is a sectional view taken along line AA, FIG. 4 is a sectional view taken along line BB thereof, and FIG.
-C sectional view, FIG. 6 is an enlarged sectional view of the vicinity of the groove provided in the bottom of the pond. As shown in FIG. 3, the water depth of the pond is shallow in the part away from the ball collecting path 8, becomes deeper as it approaches the ball collecting path 8, and becomes deepest in the part near the ball collecting path 8. At the bottom of the pond 2, as shown in FIG. 2, a groove 9 is formed, one end of which extends to the deepest part of the pond.

On both sides of the groove 9, a plurality of water flow generation nozzles 10 for generating a water flow toward the deepest part of the pond with the groove interposed therebetween.
Is installed. The water flow generating nozzle 10 is provided with the tip of the nozzle slightly facing the groove 9 from the direction toward the deepest part of the pond. The water flow generation nozzle 10 is supplied with the water of the pond pressurized by an underwater pump described later. Therefore,
The water jetted from the water flow generation nozzles 10 provided on both sides of the groove 9 collide with each other above the groove 9 and flow toward the deepest part of the pond. This forces a flow of water at the bottom of the pond towards the deepest part of the pond. Then, the ball sunk in the pond is guided onto the groove 9 by the water jetted from the water flow generating nozzle 10, and is guided to the deepest part of the pond along the groove 9.

At the upper opening of the groove 9, as shown in FIG. 6, a parallel rail 12 having a gap smaller than the diameter of the ball 11 is provided along the longitudinal direction of the groove. By providing the parallel rails 12 in this way, it is possible to separate the ball 11 from the pebbles or the like that obstruct the rolling of the ball 11 and
1 can be smoothly guided to the deepest part of the pond, which is preferable. In other words, pebbles and other balls are also ball 1 due to the water flow in the pond.
Although it is guided to the parallel rail 12 together with 1, the pebbles and the like fall into the groove 9 from the gap of the parallel rail 12, and the ball 11 rolls on the parallel rail 12 and is guided to the deepest part of the pond.

The gap w between the parallel rails 12 is about 25 mm with respect to the diameter of the practice ball 11 (about 42 mm).
Is desirable. If you make this gap too wide,
This is because the ball 11 may get stuck in the gap between the parallel rails 12 and may not move. Further, in the above example, although only one groove 9 is provided, depending on the shape and scale of the pond,
It is desirable to provide a plurality of grooves radially from the deepest part of the pond, and to provide water flow generation nozzles on both sides of each groove in the same manner as described above.

At the deepest part of the pond, a spouting means 13 is installed to spout the balls 11 guided to the bottom of the pond up to the water surface of the pond. FIG. 7 shows an example of the jetting means. The spouting means 13 shown in the drawing is a ball 1
It is composed of a spray nozzle 15 for spraying 1 together with the water of the pond above the water surface of the pond, a ball 11 sprayed by the spray nozzle 15 and a spray cylinder 16 for guiding the water above the water surface of the pond. As the spout 16
A practice ball having a diameter of about 42 mm and an inner diameter of about 50 mm was used as a cylinder. The blow-up cylinder 16 has a lower end submerged in the deepest part of the pond, and an upper end protruding upward from the water surface of the pond. The lower end of the blow-up pipe 16 is fitted to the ejection portion of the blow-up nozzle 15. . In addition, the ball 11 is provided at the lower end of the blow-up cylinder 16.
A suction pipe 17 for sucking in the water of the pond is branched and formed.

A submersible pump 18 is submerged in the deepest part of the pond, and the submersible pump 18 supplies the pressurized pond water to the water flow generating nozzle 10 and the jet nozzle 15. Therefore, the water ejected from the ejection nozzle 15 is guided by the ejection cylinder 16 and ejected above the water surface of the pond. At this time, due to the Venturi effect, the pressure in the vicinity of the ejection portion of the ejection nozzle 15 decreases and the suction pipe 1
Water from the ball 11 and pond is spouted from the suction port 7
Is sucked into. Then, the ball 11 is ejected above the water surface together with the water ejected from the ejection nozzle 15.

By the way, as shown in FIG. 7, when the lower end of the spouting cylinder 16 fitted to the spouting nozzle 15 is simply submerged in the deepest part of the pond, the ball guided to the deepest part. There is a possibility that 11 may sneak into the lower side of the blow-up cylinder 16 and become stagnant there. In order to prevent this, it is desirable to cover the blowing means 13 with the wire net 20. in this case,
As shown, the suction port of the suction pipe 17 and the spout 16
Only the upper end of the wire is projected upward from the wire net 20.

In this way, the suction port of the suction pipe 17 is connected to the wire mesh 2.
When the ball 11 is projected upward from 0, in order to smoothly suck the ball 11 from the suction port of the suction pipe 17, it is necessary to float the ball higher than the protrusion amount L of the suction pipe.
Therefore, in this embodiment, the auxiliary nozzle 21 is provided on the lower side of the wire net 20, and water is jetted upward from the lower side of the wire net 20 to float the balls. The auxiliary nozzle 21 is supplied with pressurized pond water from the submersible pump 18.

As described above, when the balls are floated, it is possible to prevent a plurality of balls from interfering with each other and clogging the suction port together with the vortex flow of water that is sucked into the suction port of the suction pipe 17. . In addition, in order to effectively prevent the plurality of balls from being clogged in the suction port, it is desirable that the amount of protrusion of the suction pipe 17 be approximately 1/2 or more of the ball diameter. By the way, it is desirable that the projection amount h of the spouting cylinder 16 above the water surface of the pond be kept to a necessary minimum. This is because the pressure of the jetted water jetted from the jet nozzle 15 can be small and the burden on the submersible pump 18 can be reduced.

The ball 11 blown up above the water surface by the jetting means 13 is received by the receiving means provided above the water surface of the pond, and the ball collecting path 8
Be led to. In the embodiment shown in FIG. 7, the jetting means 13
The portion of the wire net 20 covering the above portion that is above the water surface functions as this receiving means. In this case, the ball 11 spouted together with the water in the pond is separated from the water by the wire net 20, is swept away by the inclination of the wire net 20 and the force of the spouted water, and is guided to the ball recovery path 8. At this time, it is desirable to adjust the position of the spray port of the spray cylinder 16 so that a part of the sprayed water flows into the ball recovery passage 8. This is because the water can flow into the ball recovery passage 8 so that the balls 11 can smoothly roll in the ball recovery passage 8.

In the embodiment described above, the ball recovery path 8
Although the groove 9 is provided at the bottom of the pond for guiding the ball 12 to the above, the structure shown in FIGS. 8 to 10 may be adopted. That is, as shown in FIG. 8, the water flow generation nozzles 10 may be arranged on both sides of the valley-shaped depression on the bottom of the pond without providing the groove 9. Further, as shown in FIG. 9, the water flow generation nozzle 10 may be provided above the valley-shaped recessed portion of the bottom surface of the pond.

Further, as shown in FIG. 10, the water flow generating nozzle 10 may be installed in the groove 9 provided at the bottom of the pond. In the above embodiment, the blowing means 13 is only submerged in the deepest part of the pond, but the blowing means 13 may be embedded in the bank forming the deepest part of the pond. In addition, FIG.
As shown in, the auxiliary nozzle 21 may be installed so that the water jetted from the nozzle jets to the side of the suction port of the suction pipe 17. When the auxiliary nozzle 21 is installed in this way,
Stir the balls that are attracted to the suction port and gather,
It is possible to prevent a phenomenon in which a plurality of balls interfere with each other and clog the suction port.

Further, as shown in FIG. 12, the suction pipe 1
By forming the notch 17a wider than the ball diameter in the suction port of No. 7, it is possible to make the flow of the ball into the suction port smoother. By the way, in the above embodiment,
Although the water in the pond pressurized by the submersible pump 18 is ejected from the water flow generation nozzle 10 or the like, compressed air may be ejected instead of the water. In this case, an air pump may be provided instead of the submersible pump 18.

As shown in FIG. 1, a target green 23 is provided close to the pond 2, the surface of the green is inclined toward the pond 2, and the practice ball turned on the green 23 rolls on the pond 2. By making it fall, it is possible to positively utilize the pond 2 as a ball collecting means.

[0026]

As described above, according to the present invention,
The practice balls that enter the pond are collected in the deepest part of the pond by the water flow generator, then blown up above the water surface by the blowing means, received above the water surface by the receiving means, and introduced into the ball recovery path. Therefore, even during business hours, you can easily collect practice balls sunk in the pond without losing the view of the open space. Therefore, the utilization efficiency of the practice ball is improved. Further, according to the present invention,
Since a complicated structure that operates mechanically is not required, it is possible to solve all of the above-mentioned conventional problems such as inexpensive construction, low frequency of failure, and easy maintenance.
