[Detailed description of the invention] (Field of industrial application) The present invention relates to a ball removal device for a golf ball recovery vehicle. The removal wheel is tilted in the front-rear direction and is moved in front of the front wheel by a steering device in the same direction and at the same angle as the steering direction of the front wheel, so that the golf ball is bounced and removed so as not to be trampled by the front wheel. It is.
The second device is the same as the first device, but also includes a divided exclusion ring in the shape of a Western barrel-shaped exclusion wheel cut into rings, thereby further improving the above-mentioned effects of the first device.

(Prior Art) As disclosed in Japanese Utility Model Application Publication No. 60-132761, it is known to provide a golf ball recovery vehicle with a ball guide (ball removal device). However, no prior art has been found that can be compared with the first and second inventions of the present invention.

(Problem to be solved by the invention) This invention eliminates golf balls scattered in the direction of travel of the front wheels of the golf ball recovery vehicle, especially in the direction of steering and turning, by bouncing and rolling them without crushing them with the front wheels that change direction. The problem to be solved and the purpose of the invention is to obtain a configuration that will do the same.

(Means for Solving the Problem) The ball removal device of the golf ball recovery vehicle of the first invention of the present invention is a three-wheel type with one front wheel and two rear wheels or an even-numbered wheel type, and the front wheels are steered by a steering device to drive the ball. An arm that pivots in the same direction and at the same angle as the front wheels is connected to the front side of the front wheels of the golf ball collecting vehicle to be run, and a chain or the like hanging from the front end of the arm is bendable in the front-rear direction. A barrel-shaped ball exclusion wheel whose center part is in contact with the ground is pivotally supported at the lower end of the support, and the exclusion wheel is tilted to follow the topography and moved forward in the steering direction of the front wheels by steering. This meets the above objectives.

The ball removal device of the golf ball recovery vehicle of the second invention is a three-wheel type with one front wheel and two rear wheels, or an even number wheel type, and the ball removal device is a three-wheel type with one front wheel and two rear wheels, or an even number wheel type. , a barrel-shaped ball that is connected to an arm that turns in the same direction and at the same angle as the front wheels by the steering device, and whose center part is grounded on the lower end of a bendable support such as a chain hanging from the front end of the arm. The ball exclusion ring, which is supported pivotably by the shaft, is made up of multiple divided exclusion rings each having a western barrel shape cut into the center and its left and right sides. A shaft hole with an enlarged inner diameter is provided, each of the divided exclusion wheels is tilted in the axial direction following the topography, and the left and right divided exclusion wheels are moved in the radial direction and rotated when touching the ground. It is characterized by moving the steering wheel to the front in the steering direction, and the first device is a specific device, and the device has the same industrial field of application and problem to be solved as the specific device.

(Example) Figures 1 to 5 of the accompanying drawings illustrate the first invention of the present invention, in which Figure 1 is a schematic side view, Figure 2 is a plan view of the towing vehicle in Figure 1, and Figure 3 is a schematic side view. 4 is an enlarged plan view of the main part, FIG. 4 is a side view of the same, and FIG. 5 is a partially cutaway front view of the barrel-shaped ball ejecting wheel. FIG. 6 is a partially cutaway front view of the barrel-shaped ball ejecting wheel of the second invention.

In Figures 1 and 2, reference numeral 1 indicates a golf ball recovery vehicle, and a towing vehicle 2 is a self-propelled type equipped with a gasoline engine, and is a three-wheeled type, consisting of one front wheel 3 and two rear wheels 4. , the antenna 5 receives wireless commands to enable remote control operation. 6 is a towed vehicle towed by a towing vehicle 2, which is equipped with a recovery box 7 and is equipped with a collection box 7 at the rear (as is known in the art).
A collection drum 8 (see Japanese Patent Publication No. 5811) is attached, and golf balls B collected by the drum 8 are temporarily stored in a collection box 7. The towing vehicle 2 may be a four-wheeled truck.

A steering device 10 is provided inside the tow vehicle 2 to steer the front wheels 3 using a steering wheel or a remote control command. The steering device 10 is provided with an arm 11 that turns almost horizontally and in the same direction and angle as the front wheels 3, and a first piece 12 on the lower surface of the tip of the arm 11 is equipped with a chain such as a chain made up of several chain pieces. A support body 13 that can be bent in the front-rear direction is attached, and a downward U-shaped frame 16 is supported on the shaft 15 of a second piece 14 attached to the lower end of the support body 13, and the frame 16 is bent in the width direction of the towing vehicle 2. A barrel-shaped ball exclusion ring 18 is pivotally supported on a shaft 17 passed through the shaft.

Due to manufacturing reasons, the ball exclusion ring 18 has a central piece 19 with the largest outer diameter, left and right first outer pieces 20a and 20b with intermediate outer diameters, and a second outermost piece, as shown in FIG. 21a, 21b and a washer 22 interposed between each piece, and is housed in the U-shaped frame 16 so as not to move in the axial direction, and each center hole is fitted into the shaft rod 17 so as to rotate freely. Make a Western barrel shape with the largest outer diameter and the smallest outer diameters at both ends.
However, it may be molded as a single piece.

As illustrated in FIG. 6, the second device includes two divided exclusion rings 19 ₁ at the axial center of the ball exclusion frame 18 ₁ ,
19 ₂ , and split exclusion wheels 20 ₁ and 20 with moderate outer diameter.
₂ and the outermost divided exclusion wheels 21 ₁ , 21 ₂ make the overall shape into a Western barrel shape, and the divided exclusion wheels 19 ₁ , 1
The shaft hole of 9 ₂ is formed to match the outer diameter of the shaft rod 17 ₁ ,
The shaft holes of the divided exclusion rings 20 ₁ , 20 ₂ have an inner diameter D ₁ that allows the outer periphery to be the same in the horizontal direction as the outer circumferential lower surface of the divided exclusion rings 19 ₁ , 19 ₂ , and the shaft holes of the divided exclusion rings 21 ₁ , 21 ₂ have the outer periphery Let be the inner diameter D ₂ that can be made horizontally the same as the outer circumferential lower surface of the divided exclusion rings 19 ₁ and 19 ₂ .

(Function) The first invention of the present invention is that when the terrain to be towed is horizontal, the ball exclusion wheel 18 rolls with the center part where the outer diameter is the largest touching the ground, and when the front wheel 3 is steered, the ball removal wheel 18 rolls as shown in FIG. As shown, the front wheel 3 of the arm 11 is
Even if there are three wheels, the front side of the front wheel 3 is covered by the center part of the ball exclusion wheel 18 that is always in contact with the ground, and the ball exclusion wheel 18 moves in the same direction and at the same angle as the ground.
The gap between the two wings of the ball B is always less than the radius of the ball B, and when the ball removal wheel 18 hits the balls B scattered on the ground, it bounces outward and forward, and the ball B is thrown by the front wheel 3.
Do not step on it. In addition, if the terrain has an inclination x such as a depression, the ball removal wheel 18 is barrel-shaped, so the right or left part of the center part touches the ground, rolls, bounces forward, and removes the ball, and The gap between the ball B and the ground is maintained at about the radius of the ball B.

The second idea is that when the terrain to be towed is flat, the split exclusion wheel 19 in the center of the ball exclusion wheel 18 ₁ in the axial direction
₁ and 19 ₂ rotate without moving in the radial direction of the shaft rod 17 ₁ , and the divided exclusion rings 20 ₁ and 20 ₂ have different outer diameters, so the difference between the inner diameters D ₁ and D ₂ of the shaft holes The golf ball B rotates while contacting the ground at the same peripheral speed while changing the rotation speed
increase the elimination rate. In addition, in places where there is the slope x described above, the inner diameter of each center hole is reduced at the point where the slope x begins.
Due to the difference between D ₁ and D ₂ , as shown in Figure 6, all the wheels have different center heights of their shaft holes and each rotates independently, and this ground rotation of all divided exclusion wheels causes the ball to be thrown by the front wheel 3. It can almost completely prevent treading.

(Effect) The first invention of the present invention is that when steering the front wheels 3 of the golf ball recovery vehicle, the front side of the front wheels 3,
The arm 11, which turns in the same direction and at the same angle, is configured to steer a barrel-shaped ball exclusion wheel 18 by varying angles, and the ball exclusion wheel 18 is a wheel such as a chain hanging from the front end of the arm 11. Because it is supported at the lower end of the support body 13 that bends in the direction of travel, the barrel-shaped ball exclusion wheel 18 Not only can the ball be rotated according to the terrain, but also a ball removal wheel is provided that guards the front side of the front wheel 3 and removes the golf ball B, as described above, so that golf balls that are stepped on by the front wheel and become unrecoverable can be prevented. This has the effect of providing collection vehicles that are rarely available.

In addition, the second invention replaces the Western barrel-shaped ball exclusion ring of the first invention with a plurality of divided exclusion wheels each having a Western barrel shape cut into rings at the center and on the left and right sides thereof.
A shaft hole with an enlarged inner diameter is provided on the left and right divided exclusion rings,
The present invention has a configuration in which each of the divided exclusion wheels is tilted by a support body following the topography, and the left and right divided exclusion wheels are grounded and rotated from the radial direction, thereby further enhancing the effects of the first invention.
