DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire burying machine for burying an electric wire in the ground such as burying an electromagnetic induction wire for guiding and steering a golf ball recovery work vehicle.

[0002]

2. Description of the Related Art Conventionally, the burying work has been performed by manually digging a groove for burying an electric wire or excavating the groove with a groove digging machine.

[0003]

Conventionally, it took a long time to excavate and backfill a groove and required a lot of labor, resulting in poor work efficiency. In particular, in the case of a grass surface such as a golf course, a groove wider than necessary was excavated and the grass was damaged, which was not preferable. If the lawn is cut and removed in advance so as not to damage it, much more time and labor is required for the removing work and the laying work after burying the electric wire. An object of the present invention is to make it possible to bury an electric wire efficiently and to bury the wire particularly advantageously in the case of a lawn surface.

[0004]

DISCLOSURE OF THE INVENTION In order to achieve the object, the present invention is a disk cutter which is rotationally driven about a lateral axis of a machine body to form a groove on the ground as the self-propelled machine body travels. Is a wire burying machine in which the self-propelled machine body is provided with a wire feeding device for feeding and feeding the wire into a groove formed by the wire feeding device, and a compression ring body that acts to close the groove after the wire is fed by the wire feeding device. .

[0005]

When the machine is run, the disk cutter rotates around the lateral axis of the machine to form a groove having a width as narrow as the thickness of the cutter, and the wire supply device supplies the wire to the groove. , The crushing wheel acts to crush the groove after the electric wire is supplied, and closes the groove without disturbing the ground surface as much as possible.

In the second aspect, the scraper can discharge the earth and sand in the groove so that the electric wire can easily enter, and the electric wire guide pipe can guide the electric wire to enter the predetermined depth.

In the third aspect of the present invention, the traveling wheel and the compression wheel are grounded before and after the disc cutter to regulate the depth at which the disc cutter can enter. Therefore, by adjusting the mounting height of the compression wheel, the ground posture of the self-propelled vehicle changes around the axle axis, and the depth at which the disk cutter can enter can be changed and adjusted. That is, the depth of the groove can be adjusted.

According to a fourth aspect of the present invention, the turning center is set by the turning arm, the machine is smoothly turned so as not to meander and the width of the working groove does not easily change, and the electric wire has a desired radius. Curved embedding can be performed so that it can be smoothly curved and buried.

[0009]

Since the electric wire can be automatically buried by the action of the disk cutter, the electric wire supply device and the compression wheel body, the electric wire can be buried efficiently and easily only by running the machine body. Moreover, since a narrow groove is formed and the groove is closed by pressure suppression,
Even in the case of turf surface, it is now possible to do burial work advantageously without damaging the turf.

According to the second aspect of the present invention, since the burial depth can be accurately set to the predetermined depth by the discharging action of the scraper and the guiding action of the electric wire guiding pipe, the electric wire can be buried in the desired depth as much as possible over the entire length. Will be able to.

In the third aspect of the present invention, since the compression wheel body can be used as the adjusting means to adjust the groove depth, it becomes excellent in that the burial depth can be changed as necessary. , Relatively advantageous in terms of structure and economy.

According to the fourth aspect of the present invention, since the curve burying can be performed more smoothly and more accurately, the electric wire burying with good finishing accuracy can be efficiently performed even from the curved burying surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, a disk cutter 3, an electric wire supply device 10, on the rear part of a self-propelled vehicle having a pair of left and right traveling wheels 1, 1, an engine E, a steering handle 2, and the like.
The compression wheel body 20 is provided to configure a walk-manipulation type electric wire burying machine. This electric wire burying machine is mainly used for burying an electric wire as an electromagnetic induction wire for guiding and steering a golf ball recovery work vehicle in a golf driving range, and in detail, it is configured as follows. There is.

A traveling mission case 4, a machine body front frame 5 extending from the traveling mission case 4 to the front side of the machine body, and a traveling mission case formed so as to extend from the traveling mission case 4 to the rear side of the machine body. 4, an excavation drive chain case 6 and a rear body frame 7 extending rearward from the excavation drive chain case 6
Thus, the body frame of the self-propelled body is formed, the engine E is mounted on the front portion of the body front frame 5, and the left and right traveling wheels 1, 1 are mounted on the lower portion of the traveling mission case 4.
1 is attached. The rotation output of the engine E is transmitted to the traveling mission case 4 by belt transmission, and is transmitted from the traveling mission case 4 to the axles of the left and right wheels 1 and 1, respectively, so that the left and right wheels 1 and 1 can be driven. .

The pair of left and right traveling wheels 1 and 1 are arranged so as to rotate around the same axle core 1a and are attached to the traveling mission case 4. As a result, the left and right traveling wheels 1, 1 become one traveling wheel in a side view of the machine body, and support the self-propelled machine body while allowing the self-propelled machine body to swing around the axle core 1a.

The disc cutter 3 is an excavation disc having radial cutouts on its outer periphery, and is attached to the excavation drive chain case 6 so as to rotate about an axis 3a of the machine sideways. The excavation drive chain case 6 transmits the turning power transmitted from the traveling mission case 4 to the rotation support shaft of the disc cutter 3, so that the disc cutter 3 is located between the left and right wheels 1, 1 and is behind the traveling wheel 1. The groove is excavated in the ground by being rotationally driven in the reverse rotational direction U to the drive rotational direction F.

The electric wire supply device 10 is constructed such that the electric wire reel R is supported by a support shaft 11 so as to be detachably and rotatably supported, and is brought close to the rear part of the reel support frame 12 and the disk cutter 3 attached to the chain case 6. Scraper 13 attached to the rear frame 7 of the fuselage,
The scraper 13 is composed of an electric wire guide pipe 14 attached to the rear portion of the scraper 13 as shown in FIG. Scraper 13
Is formed so that its bottom portion is flush with the lower end of the disk cutter 3, so that the disk cutter 3 moves inside the groove formed on the ground. As shown in FIG. 4A, the electric wire guide pipe 14 is formed so that the lower end side is located inside the groove formed by the disk cutter 3, so that the electric wire C from the electric wire reel R can be inserted from the upper end side opening. The electric wire C is guided to the bottom of the groove by passing through the lower end side opening of the groove to the bottom of the groove. Thereby, the electric wire supply device 10 cleans the groove formed by the disk cutter 3 with the scraper 13 so that the earth and sand do not remain, and the electric wire C from the electric wire reel R attached to the reel support frame 12 is moved by the electric wire guide pipe 14. The electric wire C is fed into the groove from the electric wire reel R by being guided into the groove after the scraper action and rotating the electric wire reel R by the tension generated in the electric wire C for traveling the machine body.

The compression wheel body 20 is disposed on the rear side of the machine body with respect to the disk cutter 3 so as to be grounded on the ground after passing through the electric wire guide pipe 14, and the rear body frame 7 of the machine body via the wheel body support shaft 21. It is attached to the support cylinder portion 7a. As a result, the compression wheel body 20 grounds and supports the machine body on the rear side of the disk cutter 3 as shown in FIG. 1 to regulate the depth of penetration of the disk cutter 3 into the ground, and as shown in FIG. As described above, the groove after the supply of the electric wire is closed by suppressing the weight on the ground after the electric wire is supplied by the weight of the compression wheel body 20 and the weight of the machine body hanging on the suppression wheel body 20. When the adjustment handle 22 mounted on the upper end of the wheel support shaft 21 is rotated, the compression of the wheel support shaft 21 is suppressed by the action of the screw mechanism (not shown) located inside the wheel support shaft 21. The wheel body support shaft 21 expands and contracts so that the wheel body side support shaft portion 21a that rotatably supports the wheel body 20 moves up and down with respect to the machine body side support shaft portion 21b that is connected to the support cylinder portion 7a. . Therefore, by adjusting the expansion / contraction of the wheel support shaft 21 by the turning operation of the adjustment handle 22, the mounting height of the compression wheel 20 to the self-propelled vehicle can be adjusted, and the groove depth can be adjusted.

A support pipe 30 arranged near the base of the steering handle 2 is attached to the body frame. The support pipe 30 is for attaching the turning arm 31 to the self-propelled aircraft, and the base end side of the turning arm 31 is inserted into the left end side or the right end side of the support pipe 30 to make the turning arm 31
When fixed by a lock pin (not shown) configured to be inserted through the support pipe 30 and the support pipe 30, the revolving arm 31 extends from the self-propelled aircraft to the left lateral outer side or the right lateral outer side. Regardless of whether the turning arm 31 extends in the left or right direction, the extension length of the turning arm 31 from the self-propelled vehicle can be adjusted by adjusting the insertion length of the turning arm 31 into the support pipe 30. Inclining the self-propelled vehicle so that it tilts slightly toward the side where the swing arm 31 extends, regardless of whether the swing arm 31 is extended leftward or rightward and the extension length is adjusted to any length. When operated, the lower end side of the pile bar portion 31a, which is provided at the tip of the revolving arm 31 and which faces upward and downward of the machine body, has the lower end side of the disk cutter 3 in plan view of the machine body.
Ground on the extension of the rotary shaft core 3a. As a result, FIG.
As shown in, the turning arm 31 enables the self-propelled vehicle to turn about the ground contact point as the turning center.

In short, when this electric wire burying machine is run on the field of a golf driving range, as the machine runs,
The disc cutter 3 is rotationally driven in the reverse rotation direction U with respect to the traveling wheel 1 to excavate the grass surface by up-cutting to form a groove as narrow as the thickness of the disc cutter 3. At this time, since the traveling wheel 1 and the compression wheel body 20 support the vehicle body by their grounding, the depth of the disc cutter 3 entering the turf surface is restricted to a depth determined by the mounting height of the compression wheel body 20. By doing so, the depth of the working groove is
The depth is set by adjusting the mounting height of. At the same time when the disk cutter 3 makes a groove, the electric wire supply device 10 discharges the earth and sand in the groove by the scraper 13 so as not to obstruct the entry of the electric wire, and the electric wire is inserted into the groove where the earth and sand are eliminated and the electric wire easily enters the predetermined depth Induction pipe 14
The electric wire C from the electric wire reel R is guided by and supplied. The electric wire C is closed at a predetermined burial depth by closing the groove while preventing the crushing wheel 20 from crushing the groove to which the electric wire is supplied by the electric wire supply device 10 and damaging the turf surface. Can be buried automatically. When the aircraft is turned, the turning arm 31 is extended from the body toward the inside of the turning, and the extension length of the turning arm 31 from the body is adjusted to a length determined by the radius of the desired curved embedding for turning. The pile bar portion 31a of the arm 31 is grounded.
Then, the revolving arm 31 causes the rotary shaft core 3 of the disk cutter 3 to rotate.
The turning center is set on the extension line of a, and the machine body is smoothly turned so that the groove formed by the disk cutter 3 is less likely to meander or change in groove width. As a result, it is possible to perform a curved embedding in which the electric wire C is curved and embedded so as not to meander with a desired radius.

[Other Embodiments] The present invention is not limited to a two-wheel system having a pair of left and right wheels, but a single-wheel system having a single wheel as shown in FIGS. 6 and 7. Can also be applied. In the case of the one-wheel type, as shown in the figure, the traveling wheel 1, the disc cutter 3, and the scraper 13 are arranged in a straight line, and the traveling wheel 1 is disposed behind the disc cutter 3 in addition to the compression wheel 20. A pair of left and right rear wheels 35, 35 that ground and support the airframe laterally outside the vehicle wheel 1 may be provided on the self-propelled airframe to stabilize the airframe.

Instead of the one-wheel type compression wheel body 20 of the above embodiment, a two-wheel type compression wheel body 20 shown in FIG. 8 may be adopted. That is, a pair of left and right compression wheels 20, 20
However, they are arranged so that they are grounded separately on both sides of the groove after the electric wire is supplied. That is, the left and right compression wheel bodies 20 compress the lateral wall portions of the groove so as to deform into the groove, thereby closing the groove.
