Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling guide mechanism for an unmanned watering vehicle equipped with a sprinkler and traveling by the reaction force of water discharged.

[0002]

2. Description of the Related Art Conventionally, a technique relating to an unmanned water sprinkler equipped with a sprinkler function has been well known, for example, there is a technique disclosed in Japanese Utility Model Laid-Open No. 62-160678. This technique is configured such that the arm is rotated by the water pressure ejected from the nozzle, and the rotation of the arm is transmitted to the axle via a shaft and a gear to travel. In addition, a technique to mount a winch on an unmanned sprinkler, fix the tip of the wire pulled out from the machine to a pile, etc., and change the hydraulic reaction force at the time of water spray to the rotation of the wire drum to pull the machine and run. There was also.

[0003]

In such a conventional technique, the unmanned sprinkler vehicle does not have a steering function and is designed to go straight. However, even if the unmanned sprinkler is running straight, if the running surface has irregularities or slopes,
There was a problem that you could not carry out the spraying work because you would not be able to run straight and you would not be able to run straight, and if you were pulling with a wire, you would fall if the running direction of the aircraft and the pulling direction were different .

[0004]

The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be described. That is, in an unmanned water vehicle in which a winch and a sprinkler are mounted on the airframe, and the wire is wound and run by the reaction of the discharge pressure, the front wheel is a caster wheel, and a wire guide is provided on the axle support part of the caster wheel to insert the wire. Then, the wire guide is used as steering means.

[0005]

Next, the operation will be described. The front wheels of the unmanned water sprinkler A are the caster wheels 14, and the wire guide 15 is fixedly mounted on the axle support portion 14a.
Regardless of the state of the road surface, the caster wheels 14 are steered in the wire direction by the wire guide 15 and can move forward while reliably spraying water to the target point.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the structure of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an overall perspective view of an unmanned water sprinkler of the present invention, FIG. 2 is a plan view of an essential portion of the unmanned water sprinkler, FIG. 3 is a side view of the same, FIG. It is also a side view.

The construction of the unmanned water sprinkler of the present invention will be described with reference to FIG. The unmanned water sprinkler A of the present invention has a sprinkler mechanism B mounted at the rear of the carriage 9 and an alignment device C for the wire 1 at the front.
A wire drum 13 for winding the wire 1 in the center and a power transmission unit at the rear portion are arranged, and these are attached to the front cover 10a.
And a back cover 10b. The water sprinkling mechanism B projects a connecting pipe 2 at the rear part and connects a hose 3 for water supply,
The connecting pipe 2 is communicated with a base pipe 4 which is rotatably erected, and a nozzle 5 and a reaction plate 6 which are biased by a spring are arranged at the upper end of the base pipe 4, and the reaction plate 6 is formed by jetting water. The nozzle 5 rotates and the nozzle 5 catches up with the reaction plate 6 by the spring,
A sprinkler that repeats this and sprinkles water is constructed.

In the middle of the base pipe 4, sprinkler pipes 24, 24 project horizontally on both sides, and the end of the sprinkler pipe is inclined in the direction opposite to the direction of rotation, and an injection port is provided at the tip thereof. Therefore, when the base pipe 4 is rotated by the reaction discharged from the injection port, the water spray pipes 24, 24 are also rotated to spray water. A gear 4a is formed in the middle of the base pipe 4, and the gear 4a is erected on the carriage 9 in parallel with the base pipe 4.
1 is engaged with the transmission gear 11a at the upper end, and the transmission shaft 11
A worm 11b is engraved at the lower end of the worm 11b.
Is meshed with a wheel gear 12 fixed to the side surface of the wire drum 13 coaxially with the wire drum 13 that constitutes a winch arranged in the center of the carriage 9, and when the base tube 4 rotates, the gear 4a moves the transmission gear 11a. Rotate, transmission gear 1
The worm 11b at the lower end of the transmission shaft 11 rotates the wheel gear 12 by the rotation of 1a, the wire drum 13 coaxial with the wheel gear 12 rotates, the wire 1 is wound up, and the unmanned water sprinkler A moves forward. A one-way clutch is provided on the rotating shaft of the transmission shaft 11 or the transmission gear 11a so that the unmanned water sprinkler A does not move backward even if the water sprinklers 24, 24 rotate in the reverse direction.

Next, the traveling guide mechanism of the unmanned water sprinkler according to the present invention will be described with reference to FIGS. Unmanned watering car A
Caster wheels 14 are used as the front wheels of the bogie 9 of FIG. 1 and are arranged so as to be rotatable in the left-right direction about a rotation shaft 14b. A wire guide 15 is provided on an axle support portion 14a of the caster wheels 14 (wheel advancing). The wire 1 pulled out from the wire drum 13 is passed through the ring portion 15a of the wire guide 15 which is projected forward. Also,
The rear wheels 7, 7 are rotatably supported on the axle 8.

The configuration of the aligning device will be described. The aligning device C includes a slide body 18, a feed shaft 25, a slide body fixing member 19, wire guide frames 19a, 19a, a plurality of sprockets 20a, 20b, 20c and chains 21a, 21.
b and the like. Then, the sliding body 18 penetrates the feed shaft 25, and the sliding body fixing member 19 is fixed to the sliding body 18 to penetrate the guide shaft 16 which is placed in parallel with the feed shaft 25, and the wire 1 is passed through. When the feed shaft 25 rotates, the sliding body 18 reciprocally slides left and right, and is aligned when being wound around the wire drum 13.

When the wire drum 13 is rotated by the operation of the water sprinkling mechanism B, the sprocket 20a on the rotary shaft 22 of the wire drum 13 is rotated, and the sprocket 20b is driven via the chain 21a. The sprocket 20c rotates further via the chain 21b, and the feed shaft 25 of the aligning device C rotates. When the feed shaft 25 rotates, the sliding body 18 slides left and right, aligns with the wire drum 13, and winds the wire 1. As described above, by mounting the wire aligning device, it is possible to prevent the wires from being entangled with each other and causing troubles during water spraying.

Since the unmanned water sprinkler A is constructed as described above, the caster wheels 14 run in the direction in which the wire 1 is pulled, as shown in FIGS. 4 and 5, for example.
As shown in FIG. 4, even when the wire stoppers 23, 23 ... Are erected at the sprinkling place in a zigzag manner, the height of the wire stopper 23 is lower than the ground height of the unmanned watering vehicle A in advance, and the ring portion of the wire guide 15 is If 15a is set higher than the wire stopper 23, when the unmanned water sprinkler A approaches the wire stopper 23, the wire 1 is disengaged upward from the wire stop 23, and the unmanned water sprinkler A is not caught by the wire stopper 23. Run in the direction of the wire stopper 23 while sprinkling water. Reference numeral 17 is a pile that fixes the tip of the wire.

[0013]

Since the present invention is constructed as described above, it has the following effects. That is, since the front wheel is a caster wheel and is guided in the direction in which the wire is pulled by the wire guide, the caster wheel can be pulled in the direction in which the wire is pulled even if the place where the water is sprinkled is inclined or when the user wants to run in a zigzag to sprinkle the water. You can accurately drive and spray water.
