Description

[Detailed description of the invention] The present invention relates to a watering device mainly used for irrigation or spraying of chemicals and liquid fertilizers in forestry, fruit cultivation, etc., and more specifically, the method of adjusting the inclination direction and angle of the watering device in such a watering device. It is related to the 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. A water sprinkler 3 is attached to the tip 1a of a water guide pipe 1 which is formed by connecting telescopic pipes to each other in a flexible manner. When this sprinkler device A is installed on a sloped surface such as in a mountainous area, it is necessary to tilt the sprinkler 3 according to the inclination angle of the slope and direct the nozzles 4, 4 in the appropriate direction. Therefore, a spherical joint member 2 for angle adjustment is interposed between the water guide pipe 1 and the water sprinkler 3, so that the water sprinkler 3 can be bent with respect to the water guide pipe 1 by the spherical joint member 2. I was doing it.

However, since this spherical joint member 2 is relatively expensive, if the spherical joint member 2 is used for adjusting the nozzle angle of the water sprinkler 3, the cost of the entire water sprinkler device 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 device itself. There were problems such as.

In view of the above-mentioned conventional problems, this invention arbitrarily adjusts the directional direction of the water sprinkler in the horizontal plane (i.e., water sprinkling direction, hereinafter simply referred to as the directional direction) and the vertical angle (hereinafter simply referred to as the tilt angle). It is an object of the present invention to provide a water sprinkler device that can be used at low cost and has excellent durability.

The present invention, as a means to achieve the above object, supports a water guide pipe having appropriate hardness and flexibility and having a water sprinkler attached to its tip with a self-supporting water guide pipe support device. , 180 mm in the horizontal plane at the upper end of the water pipe support device.
Two or more chain hanging rods intersecting each other at an angle smaller than ゜ are installed radially outward from the upper end of the water guiding pipe support device, and between the chain hanging rods and the tip of the water guiding pipe. At least two or more chains are stretched across the pipe, and the length of the chain between the tip of the water guide pipe and the chain hanging rod can be adjusted as appropriate for each chain.

With this configuration, the length of the chain between the tip of the water guide pipe and the chain hanging rod can be adjusted to fix the tip of the water guide pipe in any direction and at any inclination angle. It becomes possible.

Hereinafter, the present invention will be explained based on the embodiment shown in FIG. 2. FIG. 2 shows a water sprinkler B according to the embodiment of the present invention.

This water sprinkler B has a water sprinkler 12 at the tip 10a.
A water guide pipe 10 with a water guide pipe 10 attached to the water guide pipe 10
and a nozzle angle adjustment device 25 that bends the water guide pipe 10 to adjust the orientation direction and the vertical angle of the water sprinkler 12 in the horizontal plane.

The water guide pipe 10 is made of a synthetic resin pipe such as a polyethylene pipe having appropriate hardness and flexibility, or a metal flexible pipe, and has two nozzles 13 at its tip 10a facing outward in the left and right direction. A sprinkler 12 with 13 is installed. The lower end 10b of the water conveying pipe 10 is inserted into the rising part 11a of a fixed pipe 11 for water supply buried underground, and the tip 1 of the fixed pipe
It is telescopically connected to the fixed pipe 11 by a pipe joint member 14 provided at 1b. Watertightness between the water guide pipe 10 and the fixed pipe 11 is maintained by a packing (not shown) provided in the pipe joint member 14. The water guide pipe 10 configured as described above is supported by a water guide pipe support device 15.

The water guide pipe support device 15 is composed of an L-shaped fixed rod 17 and an L-shaped movable rod 16 that slides vertically along the fixed rod 17. The fixed rod 17 has its lower end 17b embedded in the concrete base 30 and stands on its own. A rod securing band 19 is attached to the upper end 17a of the fixing rod 17. This rod lashing band 19 is the third
As shown in the figure, it is composed of a square-shaped base material 22 fixed to a fixing rod 17 and a pair of square-shaped tightening members 23, 23 attached to the base material 22, and a handle-attached tightening bolt 21. By tightening, the movable rod 16 and the water guide pipe 10 are separated from the fixed rod 17.
and can be fixed at any vertical position at the same time. On the other hand, the upper end 16 of the movable rod 16
As shown in FIG. 4, a water guide pipe securing band 18 consisting of a pair of square-shaped fastening members 24, 24 is attached to a. The water guide pipe 10 is fixedly supported on the movable rod tip 16a by a water guide pipe lashing band 18 with the tip 10a to which the water sprinkler 12 is attached projected upward by an appropriate length from the movable rod upper end 16a. ing. Water guide pipe tip 10a protruding above the movable rod upper end 16a
A nozzle angle adjustment device 25 is disposed between the upper end portion 16a of the movable rod and the nozzle angle adjustment device 25 for tilting the tip portion 10a of the water guide pipe in an appropriate direction and at an appropriate angle.

The nozzle angle adjustment device 25 has a movable rod tip 16.
Chain hanging rods 27, 27, .
8..., and the chains 28, 28
By appropriately changing the effective lengths of the water guide pipes, the tip portion 10a of the water guide pipe can be tilted in an appropriate direction and at an appropriate angle.

The chain latching rod 27 is for latching one end of the chain 28, and is constructed by attaching a rod-shaped body of an appropriate length to the upper end portion 16a of the movable rod so as to face obliquely upward. This chain hanging rod 2
7, 27... are chains 28, 28 as described later.
In order to adjust the pointing direction and inclination angle of the water sprinkler 12 by adjusting the length, the water sprinklers 12 are arranged radially outward so as to intersect with each other at an angle of less than 180° at least in the horizontal plane. Preferably, in this embodiment, the four chain retaining rods 27, 27, . The tip of the chain hanging rod 27 is bent downward to form a chain hanging part 27a.
The chain 28 is hooked to this chain hook portion 27a. The chain 28 is connected to the chain latching rod 27 by hooking the chain latching portion 27a of the chain latching rod 27 into the annular ring 28a at an appropriate position. In addition, the chain hook part 27a
By changing the chain to another annular ring 28a at an appropriate position, the length of the chain stretched between the water guide pipe tip 10a and the chain retaining rod 27 can be changed as desired.

On the other hand, a two-part chain attachment band 26 is attached to the water guide pipe tip 10a.
Four chains 28,
28 are installed.

Next, we will explain how to use the water sprinkler B of the illustrated embodiment and its function.When the water sprinkler 12 is placed at a relatively high place such as in the case of chemical spraying work, the water guide pipe 0 is extended. Also, when using water sprinkler 12 in a relatively low place such as during irrigation, etc.
When arranging the water guide pipe 10, the water guide pipe 10 is used in a reduced size. At this time, the water guide pipe 10 is fixed by loosening the rod securing band 19 provided on the water guide pipe support device 15 and allowing the movable rod 16 to expand and contract with respect to the fixed rod 17.
It can be expanded and contracted against. Sho rod lashing band 19
When the handle-attached tightening bolt 21 is tightened, the water guide pipe 10 is fixed in a fixed position together with the movable rod 16. Therefore, the water sprinkler 12 provided at the water conduit tip 10a is fixed at a predetermined installation height.

On the other hand, the water sprinkler 12 is constructed by appropriately setting the length of each chain 28, 28... of the nozzle angle adjustment device 25 and changing the relative relationship between the chains. The direction and angle of directivity can be set arbitrarily from the position as shown by the chain line in the same figure at 12' and 12''. Therefore, depending on the inclination angle of the installation location of the sprinkler 12, the nozzle can be tilted. 13,13
can be directed in the appropriate direction. In addition, when stretching the chains 28, 28..., the chains 28, 28...
Attach a turnbuckle 29 to one of the chains 28, 28, as shown in FIG. This prevents the water sprinkler 12 from vibrating due to water pressure or the like.

Next, to explain the effects of the present invention, according to the water sprinkler of the present invention, a water guide pipe with a water sprinkler attached to the tip is constructed of a material having appropriate hardness and flexibility, and the water guide pipe is attached to the tip of the water guide pipe. Since the nozzle angle adjustment device attached to the nozzle is deflected in an appropriate direction, the pointing direction and inclination angle (i.e., water sprinkling direction and water sprinkling angle) of the water sprinkler can be arbitrarily and easily adjusted. The effect is that the operability and workability are improved.

Furthermore, since the nozzle angle adjusting device is composed of a chain and a chain hanging rod for hanging the chain, it has a simpler structure than conventional spherical joint members, etc., and is made of relatively inexpensive materials. There is also the effect that the cost of the sprinkler system as a whole can be reduced.

Furthermore, 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, and the water sprinkler itself will not be damaged. This has the effect of prolonging the lifespan of.
