CONSTITUTION: A traveling unmanned road sprinkler mounts a watering mechanism comprising watering pipes 3a, 3b which extend horizontally from a vertical rotary shaft part 2 communicating with a water supply hole 1 and others and a wire winding device in which wire 5 is wound up by the reaction of the pressure of water discharged from the end nozzle 4 of watering pipes 3a, 3b. A ring-shaped guard bar 6 which makes a larger diameter than that of a circular orbit depicted by the end nozzle 4 and is located near the nozzle 4 is erected in a frame, and the guard bar 6, which is made to be folded, is installed on the middle side of the frame for constitution.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sprinkler protection device for an unmanned sprinkler equipped with a water sprinkling mechanism and a wire winding device, which winds and travels a wire in response to the discharge pressure.

[0002]

2. Description of the Related Art Conventionally, as seen in, for example, Japanese Patent Application No. 6-21053, a water sprinkling mechanism and a wire consisting of a plurality of water sprinkling pipes extending horizontally from an upright rotating shaft communicating with a water supply hose. In an unmanned water sprinkler that is equipped with a winding device and winds and travels a wire by the reaction of the water discharge pressure from the nozzle of the sprinkler pipe, there is no member that covers the rotation range of the sprinkler pipe while the sprinkler mechanism is operating.

[0003]

Therefore, for example, when confirming the working state, the operator accidentally approaches the sprinkler pipe in operation and is hit by the sprinkler pipe during rotation, or hits an obstacle. There was a risk that the sprinkler would be damaged.

[0004]

SUMMARY OF THE INVENTION The present invention solves such a problem and makes it possible to effectively protect the sprinkler pipe in a safe state during operation. Therefore, the standpipe communicating with the water supply hose is provided. An unmanned water sprinkler that is equipped with a water sprinkling mechanism consisting of a plurality of water sprinkling pipes and the like that horizontally extends from the rotary shaft of the spuning device and a wire winding device, and winds the wire in response to the discharge pressure from the nozzle of the water sprinkling pipe to travel. In the above, a ring-shaped guard rod, which has a diameter larger than the diameter of the circular trajectory drawn by the tip nozzle of each sprinkler and is located in the vicinity of the nozzle, is erected on the fuselage, and the guard rod is attached to the center of the fuselage. It is configured to be foldable and attached.

[0005]

Therefore, even if the sprinkling pipe accidentally approaches its surroundings while it is rotating, there is no danger of the foot hitting the guard rod and being hit by the sprinkling pipe. Also, safety can be secured without damaging the sprinkler pipe due to an obstacle, and
When the machine body is mounted on a carrier and transported or stored in a hangar, the machine body can be suitably miniaturized by folding the guard rod toward the center of the machine body.

FIG. 1 is a plan view showing an entire unmanned sprinkler. The front and rear parts of the machine are equipped with caster front wheels 7 and both rear wheels 8 and 8. A water sprinkling mechanism A communicating with the water supply hose 1 and a wire winding device B are mounted, and a front cover 9 and a rear cover 10 that can be freely opened and closed are provided, and the wire winding device B is fed out through a wire guide 11 at the front of the machine body. The tip of the wire 5 is configured so as to be able to be connected to the stake 22 standing upright in the sprinkling work place.

The water sprinkling mechanism A has a base pipe 12 communicating with the water supply hose 1 and fixedly installed on a machine base 23. The base pipe 12 is communicated with the inside of the base pipe 12 above the base pipe 12. A rotating shaft portion 2 which can rotate together with a lower gear 13, and on both sides of the rotating shaft portion 2, the base end portions of both sprinkler pipes 3a and 3b each having a nozzle 4 in the orthogonal direction at the tip are provided. Bosses 2a and 2b which can be detachably fitted and fixed by set bolts 14 and 14 are provided in a protruding manner, and the rotary shaft portion 2 is also provided.
Above the above, the reaction plate 15 is rotated by the injection of water to draw the nozzle 16 by the spring so that water can be sprayed while rotating.

The wire winding device B includes the gear 13
A worm gear 18 is provided on the same shaft below the transmission gear 17 that constantly meshes with the wire guide 11 and the aligning plate 1.
A worm wheel 21 that constantly meshes with the worm gear 18 is provided on the lateral side of the wire drum 20 on which the wire 5 extending through the wire 9 can be wound.

A ring-shaped guard rod 6 having a diameter larger than the diameter of the circular trajectory C drawn by the tip nozzles 4 of the sprinklers 3a and 3b and located near the outer side of the nozzles 4 is installed on the machine body. However, the guard rod 6 is composed of short front and rear guard portions 6d and 6c which are slightly bent, and long guard portions 6b and 6a which are long and curved in an arc shape. Bosses 26b and 26a that are parallel to each other are fixed to the tips of stays 25b and 25a extending from the metal fitting 24 to the left and right sides of the machine body.
6a includes water sprinkling pipes 3b and 3 removed from the rotary shaft 2.
locking pieces 27b, 27b, 27 capable of locking a
a and 27a equipped with parallel support rods 28b and 28a, the middle portions of which are fitted and fixed, respectively.
Supports 29, 29, 30, 30 at both ends of both guards 6d, 6c are fitted to the front and rear ends of 8a, respectively, and support 31, 31, 31, at both ends of both guards 6b, 6a are fitted.
32 and 32 are rotatably fitted into each supporting tool 3
Projection portions 31a, 31 protruding from 1, 31, 32, 32
a, 32a, 32a have stoppers 33, 33, 34, 34
The guard rods 6 can be engaged and disengaged, and the guard rod 6 can be folded toward the central portion of the machine body while the guard portions 6b and 6a are rotated upward by releasing the lock.

It should be noted that the rear ends of both supporting rods 28a and 28b are connected and connected, and the ends of the guards 6a and 6b are pivotally supported by the connecting parts so that the guards 6a and 6b can be folded. It can also be configured to.

Therefore, when water is sprinkled by the water sprinkling mechanism A, the rotating shaft portion 2 is caused by the reaction of the water discharge pressure from the nozzles 4, 4.
When the wire drum 20 is forcibly driven by the gear 13, the wire 5 is wound up and the machine body is advanced toward the pile 22 for unmanned water sprinkling.

As shown in FIGS. 1 and 3, the left and right guard portions 6b, 6a are rotated in the horizontal direction so as to engage the locking members 33, 3 with each other.
If the sprinkler pipes 3a and 3b are locked by being engaged by the engagement of the sprinklers 3, 34 and 34, even if the sprinkler pipes 3a and 3b are inadvertently approached around them, the foot will hit the guard rod 6. As a result, there is no danger of hitting the foot with the water sprinkling pipe, and the water sprinkling pipes 3a and 3b are not damaged by hitting an obstacle, so that safety can be ensured.

Further, when the machine body is carried by a carrier or stored in a hangar, the locking tools 33, 33, 34, 3 are used.
4 is unlocked by operating 4 and both guard parts 6
When a and 6b are rotated upward, the guard rod 6 can be folded toward the central portion of the machine body to be miniaturized, as shown in FIGS. 4 and 5.

[0014]

As described above, according to the present invention, the sprinkling pipes 3a and 3b are provided.
Even if you accidentally approach the area around it while it is rotating, there is no risk of your feet hitting the guard rod 6 and being hit by the sprinkler pipe. Therefore, it is possible to ensure safety without damaging the sprinkler pipes 3a and 3b, and when the machine is mounted on a carrier or carried or stored in a hangar,
By folding the guard rod 6 toward the center of the aircraft, the aircraft can be downsized appropriately. The guard rod 6 is highly safe and has a ring shape so that the outer circumference of the aircraft does not unnecessarily increase in size. It has features that can be suitably implemented.
