Description

[Detailed description of the invention] The present invention relates to a watering device mainly used for irrigation or spraying of chemicals, liquid fertilizers, etc. in forestry, fruit cultivation, etc., and more specifically, the inclination direction and angle of inclination of the sprinkler in such a watering device. It concerns an adjustment device.

As a conventional water sprinkler device of this kind, the one shown in FIG. 1 is known, but this conventional water sprinkler device A has a lower vertical pipe 6 and an upper vertical pipe 5, each made of a steel pipe or an aluminum pipe. The sprinkler 3 is attached to the tip 1a of a water guide pipe 1 which is formed by connecting the pipes 1 to 1 in a flexible manner.

When this watering device A is installed on a sloped surface such as a mountainous area, the watering device 3 is installed according to the inclination angle of the sloped surface.
Since it is necessary to tilt the nozzles 4, 4 in the proper direction, a spherical joint member 2 for angle adjustment is interposed between the water guide pipe 11 and the water sprinkler 3, and the spherical joint member 2
This allows the water sprinkler 3 to be bent relative to the water guide pipe 1.

However, since this spherical joint member 2 is relatively expensive, the spherical joint member 2 is used for adjusting the nozzle angle of the sprinkler 3.
If this is used, the cost of the sprinkler system as a whole will be high.

Furthermore, in winter, the interior of the spherical joint member 2 may freeze, damaging the spherical joint member 2, or causing water to leak from the spherical joint member 2, resulting in high maintenance costs for the sprinkler system itself. There were other problems.

In view of the above-mentioned problems, the present invention is based on a synthetic resin pipe with appropriate hardness and flexibility that allows it to stand on its own. The object of this invention is to provide a water sprinkler device in which the direction and angle of inclination of the water sprinkler can be adjusted by bending it in an appropriate direction by utilizing its flexibility.

Hereinafter, the water sprinkling device of the present invention will be explained based on the first embodiment shown in FIGS. 2 to 5 and the second embodiment shown in FIG. 6. The whole water sprinkler device B according to the first embodiment of the present invention is shown, which is used when the water sprinkler 11 is placed at a targeted location.

This water sprinkler B includes a water guide pipe 10 with a water sprinkler 11 attached to its tip 10a, a water guide pipe support device 15 that supports the water guide pipe 10, and a tip portion of the water guide pipe 10 that is bent to tilt the water sprinkler 11. It has a nozzle angle adjustment device 25 that adjusts the direction and inclination angle.

The water guide pipe 10 is made of a synthetic resin pipe such as a polyethylene pipe or a metal flexible pipe having appropriate hardness and flexibility so as to be able to stand on its own at least at its tip. A water sprinkler 11 having two nozzles 12, 12 facing outward in the left-right direction is attached.

The lower end portion 10b of this water guide pipe 10 is supported by a water guide pipe support device 15.

In the water guide pipe support device 15, a lashing band 17 for securing the water guide pipe 10 to the support 16 is attached to an upper end 16a of an L-shaped angle-shaped support 16 of an appropriate length, and a lashing band 17 is attached to a lower end 16b of the support pipe 16. It is constructed by embedding it in a concrete base 20, and is made to stand on its own by the concrete base 20.

The lashing band 17, as shown in FIG. The water guide pipe 10 can be fixed to the pipe 16.

A nozzle angle adjustment device 25 for tilting the tip of the water guide pipe 10 in an appropriate direction and at an appropriate angle is attached to the tip of the water guide pipe 10 that projects upward from the lashing band 17.

The nozzle angle adjustment device 25 includes three rope attachment members 26, 27.30 attached to the water guide pipe 10 from a position directly below the water sprinkler 11 to an appropriate range downward, and each of these rope attachment members 26, 27.30. It is composed of a plurality of (two in the first embodiment illustrated) cables 35, 35 stretched between the cables 30 and 30.

This nozzle angle adjustment device 23 is connected to each cable attachment member 26, 27.
．． By appropriately changing the effective lengths of the cables 35 and 35 stretched between the pipes 30 and 30,
0a can be tilted in an appropriate direction and at an appropriate angle.

In addition, in the first embodiment illustrated, a chain is used as the rope 35, so in the following, each fastening member 26, 27
, 3G are respectively called chain fastening members, and these are further called an upper chain fastening member 26, an intermediate chain fastening member 27, and a lower chain fastening member 30 in this order from the tip side of the water guide pipe 10.

The upper chain attachment member 26 is attached to the water guide pipe tip 10 by holding chain attachment bands 26a, 26a which are split into two parts.
The chains 35 and 35 are detachably attached to the upper chain attachment member 26 with a shackle or the like.

The intermediate chain fastening member 27 is connected to the upper chain fastening member 26.
It is for hanging the middle part of the chain 35, 35... stretched between the lower chain anchoring member 30 and the lower chain anchoring member 30. It is composed of hanging rods 28, 28, . . . of appropriate length, which are integrally fixed to the mounting band 29.

At least two, preferably three or more, latching rods 28, 28, .

In the first embodiment shown in the drawings, two hanging rods 28 are provided.

The end of the latching rod 28 is bent into an inverted U-shape as shown in FIG. 3 to form a chain latching portion 28a, and the chain 35 is latched to this latching portion 28a.

Incidentally, the inverted U-shaped latching portion 28a of the latching rod 28 acts to prevent the chain 35 from coming off the latching portion 28a when chain tension is applied toward the base of the latching rod.

The lower chain fastening member 30 is for fastening the lower end side of the chain 35, and is spaced an appropriate distance downward from the intermediate chain fastening member 27 and attached to the water guide pipe 1.
It is attached to 0.

This lower chain fastening member 30 includes a mounting band 32 with a split structure that is fastened and fixed to the water guide pipe 10, and hanging rods 31 and 3 of an appropriate length that are integrally fixed to the mounting band 32.
Consists of 1...

At least two, preferably three or more, latching rods 31, 31, .

In the illustrated first embodiment, two locking rods 31, 31 are provided in correspondence with the intermediate chain locking member 27.

Further, the lengths of the latching rods 31, 31 are made shorter by an appropriate dimension than the lengths of the latches 28, 2B of the intermediate chain attachment member 27, and their tips 31a are bent into an L shape (Fig. 4). .

One end of the chain 35.35 is connected to an upper chain fastening member 26 of a two-part structure attached to the water guide pipe tip 10a in the vicinity of the water sprinkler 11, and the other end is connected to the intermediate chain fastening member 27. It is hung on the hanging rod 28 of the lower chain attachment member 30 and the hanging rod 31 of the lower chain attachment member 30.

The chain 35 is attached to the intermediate chain attachment member 27 and the lower chain attachment member 27 by hooking the attachment portion 28a of the attachment rod 28 and the attachment portion 31a of the attachment rod 31 into the annular ring 35a at an appropriate position. It is hooked to the attachment member 30.

In addition, by changing the hooking of other annular rings 35a at appropriate positions to the hooking portions 28a and 31a, tension can be provided between the upper chain attachment member 26 and the attachment rod 28 of the intermediate chain attachment member 27. It is possible to arbitrarily change the length of the chain to be attached and the length of the chain stretched between the hanging rod 28 of the intermediate chain securing member 27 and the hanging rod 31 of the lower chain securing member 30. can.

Next, the method of using the water sprinkler B according to the first embodiment shown in the drawings and its function will be explained.
Nozzles 12, 1 of a water sprinkler 11 provided at the tip 10a of the water guide pipe to receive irrigation water, chemical solution, liquid fertilizer, etc.
Water is sprayed in an appropriate direction from 2 to perform watering operations such as irrigation.

During this spraying work, the nozzles 12, 12 of the water sprinkler 11
It is necessary to use the sprinkler at an appropriate inclination depending on the situation of the installation location of the sprinkler, and in the sprinkler B of the first embodiment illustrated, the nozzle angle adjustment device 25 provided at the tip 10a of the water guide pipe is operated. This allows the direction and angle of inclination of the nozzle 12.12 to be set arbitrarily.

That is, since the water guide pipe 10 has moderate visibility, the upper chain fastening member 26 and the intermediate chain fastening member 2
The length of the chain stretched between the hanging rod 28 of the intermediate chain attachment member 27 and the hanging rod 31 of the lower chain attachment member 30. By appropriately setting the length of each chain 35, 35, the water guide pipe 10 can be bent in any direction and angle.

When the water guide pipe 10 is bent, the water sprinkler 11 attached to its tip is inclined at an appropriate angle depending on the bending of the water guide pipe 10.

At this time, as shown in FIG.
6 and the hanging rods 2B and 28 of the intermediate chain securing member 27, the water sprinkler 11 can be attached to the intermediate chain securing member as shown by chain lines 11a and lla. The retaining rods 28, 28 of the intermediate chain retaining member 27 are inclined from a position directly above the intermediate chain retaining member 27.
By changing only the length of the chain stretched between the latching rods 31, 31 of the lower chain securing member 30, the water sprinkler 11 can be attached to the lower chain securing member 30 as shown by chain lines 11b and llb. It is tilted from a position directly above 30.

That is, the chain stretched between the upper chain attachment member 26 and the intermediate chain attachment member 27 and the chain stretched between the intermediate chain attachment member 27 and the lower chain attachment member 30 are each independent. In the illustrated first embodiment, the inclination state of the water sprinkler 11 can be arbitrarily set by using either or both of the chain length adjustment functions. .

Incidentally, when the chains 35 are stretched between the upper chain attachment member 26 and the intermediate chain attachment member 27 and between the intermediate chain attachment member 27 and the lower chain attachment member 30 as in the first embodiment shown in the drawings. In order to bend the water guide pipe 10 in two stages by simultaneously changing the length of the chain at the same position, it is possible to set the inclination angle of the sprinkler 11 to a larger angle as shown by chain lines 11c and llc. can.

Moreover, this chain 35 is not made into a long chain with a single joint as in the first embodiment shown in the drawings, but with a chain stretched between the upper chain fastening member 26 and the intermediate chain 4 nitrogen member 27, and the intermediate chain. The chains stretched between the chain fastening member 27 and the lower chain fastening member 30 may be separate from each other.

In this way, the operation of changing the chain for each of the locking rods 28, 31 can be made easier.

FIG. 6 shows a second embodiment of the sprinkler system of the present invention.

This second embodiment is a watering device used when the watering device 11 is installed at a relatively low place, such as when spraying liquid fertilizer.
In this water sprinkling device B, the water guiding pipe 10 is buried in the ground from a position directly below the nozzle angle adjusting device 25, and the water sprinkling device B is made independent by the self-supporting force of the water guiding pipe 10 itself.

In this way, a water guide pipe support device is not required, and the cost of the entire sprinkler system can be reduced accordingly.

Next, to explain the effect of the present invention, according to the sprinkler device of the present invention, an appropriate number of nozzle angle adjustment devices are installed to orient the nozzle of the sprinkler in an appropriate direction according to the inclination angle of the installation location of the sprinkler device. Since it is composed of a rope such as a chain and several rope attachment members for securing the rope, it has a simpler structure than conventional spherical joint members, etc., and is made of relatively inexpensive materials. The cost of the sprinkler system as a whole can be reduced.

In addition, since the nozzle angle adjustment device does not have a pipe joint like conventional water sprinklers, the pipe joint will not be damaged by freezing, etc., and water will not leak from the pipe joint, thereby extending the life of the water sprinkler itself. It can be made longer.

Furthermore, since the nozzle angle adjustment device is installed only on the water guide pipe, especially when the water sprinkler is installed at a relatively low position such as when spraying liquid fertilizer, the water guide pipe can be adjusted as shown in the second embodiment. The water supply pipe can be directly buried underground without the need for supporting equipment, allowing the sprinkler system to stand on its own, and has practical effects such as further reducing the installation cost of the sprinkler system due to the reduction in the number of parts. It is something to play.
