Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for recovering balls after hitting them at a golf driving range or the like.

(Prior Art) Ball recovery work after hitting a ball at a golf practice range or a putting center has conventionally been performed mostly manually, requiring a great deal of labor.

In some cases, devices are provided to collect sol to some extent from vehicles in motion, but this naturally requires a driver of the vehicle, and in addition, collection is not reliable. In the end, there are many parts where we have to rely on manual collection. In addition, there are some systems that collect all the balls by creating a sloped groove at the edge of the practice field) and installing a belt conveyor in this area, but they do not collect all of the balls from the edge, and most of the balls that are scattered on the wide field are left behind. It would be difficult to recover without damage. In addition, according to the conventional method, people enter the field while the ball is being collected, which is dangerous.
It is not possible to practice batting, which creates time constraints and is uneconomical.

Based on the above, it has been desired to make the ball collection work unmanned or labor-saving.

(Problems to be Solved by the Invention) The present invention attempts to gather balls scattered on a large field into a predetermined place without anyone entering the field and without using any manual effort. Therefore, if necessary, the ball can be retrieved during practice batting, and the device does not damage the appearance of the field and does not cause discomfort to those practicing. Moreover, it can be easily installed in existing practice ranges of any terrain.

(Means for solving the problem) Concerning the net laid on the field of the practice field, a traction device that pulls the net upwards to a desired position, and equipment that moves the balls collected by the net to a predetermined location. It is. In other words, when the net is laid in the field and pulled upwards, it hits! The purpose is to collect balls at a predetermined location by forming an inclined surface on the Il net.

(Example) A golf driving range or the like where the present invention is applied is a field with a certain amount of space, for example, a driving range with a distance of 30 = or more in front of the batting area, and the field λ
A pillar 3 and a side net≠ are stretched around the .

The feature of the present invention is the net j laid on the surface of the fieldco at the practice range, and the material of this net j is the same as that of the above-mentioned tomo side net hiro, and is generally made of strong synthetic resin. Naturally, the mesh is smaller than ball 6.

As shown in Figure 2, Net! edge 7 or net j1
j! : The wire r is connected to the desired position to be pulled up, and the wire r is made thick to increase the strength as necessary because it is pulled up by a traction device such as a manual handle or a motor. The locking fitting IO is used.

wire? A traction device is installed near the pillar 3, and the wire t is wound around a pulley attached to the pillar 3 and extends around the traction device. The number of covers for this chapter is
Usually, they are installed at each location of each pillar 3, but the installation location and number of devices are appropriately selected depending on the size of the field, the topography of the field, the length of the interval between the pillars 3, etc. It doesn't necessarily have to be a complete motor.

A manual handle and wire rt tow will also suffice. The key is the internet! The desired slope of the net surface can be created by lifting a portion of the net surface from the surface of the fieldco.

Now, as for how to tilt the net jt-up ff7, various forms can be considered depending on the topography of the field λ, as shown in FIG. 3(1) (slanted side view). In this case, the amount of winding of the wire t in the traction device is
There is a difference l) depending on the installation location, and this winding difference forms the slope of the net j.

In the case of a manual traction device, set the wire t hoisting difference according to the location of the traction device.

Do each portion by eye. Further, in the case of a motor-equipped traction device, each motor may be provided with an independent operation switch, and the switches may be gathered in one place and turned on and off while observing the inclination form of the net j. Alternatively, the amount of hoisting for each traction device can be determined in advance, and if the amount of hoisting differs from the set value, the entire circuit can be configured to provide mechanical or electrical feedback, and the operation switch of each motor can be automatically switched. If K is set so that K is OFF, the slope of net j can be set to a predetermined state with a single touch. The wire r may be removed, and a gear or arm that moves up and down may be directly connected to the pillar 3, or the edge 7 of the net j may be directly connected to the pillar 3.

Next, K is a method of processing nine balls j that are gathered at a predetermined place by the slope of the net j, but this is based on the topography of the field λ,
Depending on the cost of equipment etc., for example, the following number fighting method can be considered.

(1) If the slope of the net J is t-@3 (1) If the slope is K as shown in ■, the ball 6 is placed in the groove/≠ cut out on the field at the lowest slope. It can be gathered together. In this case, there is no need to provide any special mechanism to net l-J'.

(2) When the slope of the net j is made as shown in No. 390), the net is separated at the trough of the net form, and the balls 6 are collected in the nine-cut concave groove /≠ provided in the shift field λ.

(3) In the case of (1) and Q) above, it is necessary to manually collect the balls 6 gathered on the field using a rake-shaped tool (6J), making it difficult to collect the balls during business hours. Become.

In order to improve this point, in the case of the net inclination shown in Figure 3 (■), the net is not separated at the valley part of the net form, but is made into a net shape as shown in Figure 3, and an appropriate hole is inserted at the bottom of the net. Create a hole number 12 and allow ball 6 to fall through the hole. Then, the net inclination is set as the through hole in Figure 3, and a hole 4'FF) is drilled in the field λ where the bottom hole 12 of net j hits, and then from the drill hole /3, the side surface of the field ≠ Mouth groove with slope to the outside／≠
dig.

If you do this, the ball 6 that falls through the bottom hole /λ of the net J and into the excavated hole /3 on the field will automatically come out to the outside of the side net, so you can collect the ball 6 even during business hours. becomes possible.

f! In the case of A, F, and slope of Fig. 3 (1) to (3),
That is, even in the case of the ball collection methods (1) and c2), a quarter groove/hole is excavated from the field λ where the balls 6 are gathered to the outside of the side net hole,
By fitting the belt conveyor /j into the quarter #/≠, the ball 6 can be easily guided to the outside of the side net≠. Of course, this belt conveyor system can be applied as a substitute for the above-mentioned (a) inclination of the opening groove/4'. /6 is a seventh gear for driving the belt conveyor.

(b) The ball collection method in Figure 3 (3+) in (■ and C) above assumes that the balls 6 will be collected at a midpoint between the front and back of the premises, although they are said to be outside the side netting. Therefore, it is convenient for a friend to store the ball by guiding the ball 6t to either the front or back of the premises, and the following three methods can be considered for this purpose.

The first case is when the topography of the field λ is sloped and the ball 6 is stored at the lower part of the slope.

As shown in Figure J (1), excavate a groove/≠ along the slope, or bury a clay pipe or iron pipe with a diameter of about /jam, and use the slope to create a trench 6t within the site. Store it in one place at the bottom.

The second case is when the ball 6 is stored at the top of the terrain of the sloping fieldco.

As shown in Figure 5 (2), excavate a quarter groove facing the top along the slope, and insert a screw conveyor/7t into the case.
- Equipment 1 is used, and a screw conveyor is driven by a motor l♂ to guide and store balls 6t into part B of the upper part of the premises.

The third method is to guide and store the ball 6 to the rear of the field (note: the location where the batting area is located) when the topography of the Fieldco is flat.
Dig a groove /4'- to the rear of the premises, fit a belt conveyor lj, and drive a motor /6t- to make a ball j.
t-Collect at one location at the rear of the premises.

(Effects) The present invention has the structure described above, and the ball 6 that flies onto the net j laid on the fieldco
If a large number of balls are scattered and it is necessary to collect them, even during business hours, the traction device is activated to pull up a part of the net, create a predetermined slope on the net, and roll the balls 6. Alternatively, a belt conveyor/j, a screw conveyor 77, etc. can be used to automatically guide and store the balls 6 to a predetermined location.

Since the device of the present invention uses the net laid on the field as the material for the ball receiving tray, it does not matter whether the topography of the field is flat, sloped, or uneven, it can be practiced on any terrain. It can also be adapted to the venue.

Furthermore, even if grass is planted on the surface of the field, its growth will not be hindered. Furthermore, since the color of the net is the same as the artificial turf, it has many advantages such as not causing any discomfort to those practicing.It is extremely effective as a pole collection device for sports practice ranges for golf, baseball, and other ball-hitting sports.
