[Conventional technology and its issues]

Traditionally, golf driving ranges with natural grass were open almost all year round, and , open early in the morning and late at night, making it difficult to maintain and manage the natural grass. , and if the ball hits the pebbles scattered on the ground, the impact will be Since the impact force is said to be about 1 ton, there were problems such as severe damage to the ball. Moreover, the collection of used balls at golf driving ranges using natural grass requires , there were various problems. In other words, it generally takes a person to retrieve a ball that has been hit. One method is to pick up balls one by one by hand, and the other is to collect balls using a traveling automatic ball collection truck. However, in the former method of manual collection, the above-mentioned problems occur. Due to business hours, ball collection work is limited to short periods of time early in the morning and late at night, and therefore the work is It became extremely difficult to secure workers, and balls hit during and after the rain were buried in the ground and were not returned. There was a problem that it was difficult to make ends meet. In addition, the latter method using a traveling automatic ball collection vehicle damages natural grass by driving. In addition, as mentioned above, it is said that balls buried in the soil cannot be recovered. There was a problem. To further describe such a traveling automatic ball collecting vehicle, FIG. 2 is a perspective view of this embodiment. To explain with reference to this figure, there is a police box magnet in the soil at the golf driving range 1. A guide line 2 that transmits the field is laid in a loop shape, and the operation is carried out on this guide line 2, and , a guide car 3 equipped with an automatic transmission/stop device is provided, and this guide car 3 is equipped with the guide line. One front wheel 4 that guides while detecting 2 and a pair of rear wheels driven by a motor. The guide wheel 3 rotates discs 6, 6 arranged side by side at equal intervals. A golf ball collection vehicle 7 equipped with a ball collecting device consisting of a body is towed to collect scattered golf balls. The golf ball was operated while picking up golf balls, and moreover, the golf ball bypassed this guide line 2. -The golf ball goes to the ball collecting device 8, and the golf balls collected there are dropped and returned to the guide line. A traveling automatic ball collection vehicle has been proposed that departs from road 2. -65564). However, in the proposed automatic ball collecting vehicle, golf balls using natural grass are not available. Since it is applied to the golf practice field, the natural grass and soil surface are susceptible to ball impact as mentioned above. This may cause damage to the ball truck itself, and as it travels on a fixed route, it may be damaged due to ruts, etc. As a result, the running surface becomes uneven, and golf balls accumulate in these concave areas. The ball collecting truck may run over this, causing it to deviate from its driving route and come to a halt. Also During rainy weather, this concave area becomes muddy, and if the rear wheel comes into this concave area, it will slip and end up spinning. The vehicle becomes unable to run. In addition, guide lines can be used during maintenance work on natural grass and soil. There was a problem in that there was a risk of cutting.

[Means to solve the problem]

Therefore, the present invention was devised to solve the problems of the prior art. The gist is that the guide line is laid in a loop and transmits an alternating magnetic field. and a guided vehicle that operates while detecting the guideline and is equipped with an automatic transmission/stop device. and a ball rotating device that is pulled by the guide vehicle and includes a ball collecting device that rotates and collects the balls. In a ball collecting vehicle consisting of a collecting vehicle and It is buried in a loop-shaped groove formed in asphalt concrete, and the asphalt concrete Artificial turf with imitation nylon leaves planted on top of the leet and sand added between the imitation leaves. There is a ball collecting truck at a golf driving range, which is characterized by having the following affixed to it.

【Example】

The structure of the present invention will be described in detail with reference to embodiments shown in the accompanying drawings. FIG. 1 is a cross-sectional perspective view of a main part of an embodiment of the present invention, and FIG. 2 is an overall external view. This example is a golf driving range with artificial turf as described below. It has a drainage slope and a surface that matches the existing ground. Golf that does not require grooves and has a natural slope that allows you to check the ball until it stops. Suitable for practice areas. As shown in FIG. 1, the artificial turf 10 of this embodiment is made of crushed stones with a thickness of about 150 mm on the roadbed. A roadbed 11 is formed, and an asphalt concrete layer 12 with a thickness of about 50 mm is placed on top of it. Lay down. This asphalt concrete layer 12 has a depth d=approximately 15 mm and a width = Grooves 13 of approximately 10 mm are continuously opened in a loop shape at intervals of approximately 3 m with a groove pitch, The guide line 2 is laid in this groove 13, and then the opening of the groove 13 is closed with mortar 14. do. Next, on the top surface of this asphalt concrete layer 12, the following artificial Paste grass 10. That is, this artificial turf 10 has a base sheet with a pile length of approximately Imitation leaf pieces 15 made of nylon with a diameter of 20 mm are planted, and a thickness of approximately Topping sand was added to 15 to 16 mm. The color of this imitation leaf piece 15 is usually It has a distinctive green color. Next, the ball recovery device 8 of this embodiment will be described. As shown in FIG. If the loading platform of the golf ball recovery vehicle 7 is tilted in the pit 16, the golf balls will be collected and loaded. The loaded balls can be unloaded. The unloaded balls move along the guide groove 17 with circulating water. The balls are then introduced into the ball/sand separation pit 18. There are 19 drainboards installed here. The sand falls together with the water, and only the balls roll into the ball pit 20. bow The balls collected in the loop pit 20 are lifted up by an elevator 21 and then put into a washing machine. 22. Although the details of this washing machine 22 are not shown, for example, a large number of It consists of a horizontal rotating drum made of beams, and a shower pipe is attached to the outer periphery of this drum. is installed, and as the drum rotates, the rotating ball is lifted up. It will be done. The ball is washed by taking a shower in this elevated position. If a ball with sand on it is fed to the cleaning machine, this sand will act as an abrasive and - The uneven surface (rimple) of the groove is worn away, but most of the surface is removed in the separation pit 18 in advance Since the sand is removed, there is no such inconvenience. The balls are then passed through a dryer. Collected in collection box. Note that the ball recovery device of this embodiment is applicable not only to those described above, but also to various types of recovery/collection. The cleaning equipment is applied, but at least the artificial turf top dressing is needs to be dropped. In addition, the ball collection device of the golf ball collection vehicle towed by the guide vehicle 3 is a disc. A brush-like rotating body may be used instead.

[Effect of the idea]

According to the present invention, a person who pasted the material on asphalt concrete with a thickness of about 50 mm Since artificial turf is used, the guide line can be buried accurately within the asphalt concrete. At the same time, there is no problem with detection, and as a result, the guided vehicle can be operated appropriately. Especially, eye sand Since it is made of artificial turf, there is no damage to the ball or the artificial turf due to the impact of the golf ball. Not only that, there is no damage caused by ruts or other damage caused by the ball collecting truck, so the golf balls can be kept in one place. Smooth operation is possible without the guide cars derailing or idling.
