Description

[Detailed Description of the Invention] The present invention mainly relates to a watering device for spraying water, liquid fertilizer, chemicals, etc. in farms, forests, etc.

In forestry or fruit cultivation, it is necessary to sprinkle water from a relatively high place and in an appropriate direction. Therefore, conventional watering equipment for forestry or fruit cultivation uses the tip of a vertically long water guide pipe 2 as shown in Fig. 1. A water sprinkler 5 is attached to 2a via an angle adjustment joint member (spherical joint member) 8.

The water conveyance pipe 2 is composed of a lower vertical pipe 3 made of a steel pipe or an aluminum pipe, and an upper vertical pipe 4 that is slidable in the vertical direction with respect to the lower vertical pipe 3. By sliding it vertically and fixing it with a stopper device 6, it is possible to adjust the height of the water sprinkler 5 attached to the water guide pipe tip 2a (upper end of the upper vertical pipe 4) to an appropriate height. .

Note that the spherical joint member 8 for angle adjustment is used as shown in FIG.
This is to allow water to be sprayed in an appropriate direction by tilting the water in the left-right (or front-back) direction by an appropriate angle α.

This conventional water sprinkling device is supported by securing the lower vertical pipe 3 to a post 11 of a fixed length that is erected and fixed at a position adjacent to the side of the water guide pipe 2.

The height of this support 11 is formed to be approximately the same as the height of the lower vertical tube 3, and the vicinity of the upper end of the lower vertical tube 3 is secured to the vicinity of the upper end of the support 11.

However, this conventional sprinkler system has the following problems.

(1) Only the lower vertical pipe 3 of the water guide pipe 2 has a support 11.
Since the upper vertical pipe 4 is not fixed to the water sprinkler 5, the upper vertical pipe 4 is unstable and shakes due to the water pressure and impact of the water sprinkler 5, resulting in poor uniformity of watering.

In particular, when the upper vertical pipe 4 is elongated, it becomes even more unstable.

(2) The upper and lower vertical pipes 4 and 3 of the water pipe and Eve 2 are made of large-diameter steel pipes or aluminum pipes for strength reasons, making them expensive.

(3) Since the relatively expensive angle adjustment joint member 8 is used to mount the sprinkler 5 in a freely tiltable manner, the cost of the sprinkler device is high.

(4) The sprinkler 5 is fixed so as to be almost upright with respect to the slope direction of the ground using the angle adjustment joint member 8, and then the upper vertical pipe 4 is extended upward. At this time, the upper vertical pipe 4 is In many cases, the water sprinkler 5 is rotated so that it does not actually stand upright in the direction of the slope of the ground, and even if it is set upright according to the specifications during construction, the direction of the sprinkler 5 when used by farmers etc. Because they were expanded and contracted without much care, they were sometimes not used in proper conditions.

The present invention was made in order to improve the problems of conventional water sprinklers as described above, and provides a water sprinkler that can be manufactured at low cost and can be installed stably. The purpose is to

Below, the watering device of the present invention will be explained based on the illustrated embodiment. The watering device of the embodiment shown in FIGS. 3 and 4 is used for forestry or fruit cultivation, and this watering device has the following features: A water sprinkler 5 is attached to the tip 2a of a vertically long water guide pipe 2 in which an upper vertical pipe 4 is telescopically attached to a lower vertical pipe 3, and a water sprinkler 5 is installed at a position near the side of the water guide pipe 2. The structure is such that the water guide pipe 2 is stably erected by arranging a self-supporting column 11 that can be expanded and contracted in the vertical direction along the column and securing the water guide pipe 2 to the column 11.

The upper vertical pipe 4 of the water guide pipe 2 is formed of a synthetic resin pipe (flexible polyethylene pipe), and the lower vertical pipe 3 of the water guide pipe 2 is formed of a metal pipe.

The diameter of the lower vertical tube 3 is larger than that of the upper vertical tube 4, and the lower portion of the upper vertical tube 4 is slidably inserted into the upper portion of the lower vertical tube 3. , the water guide pipe 2 can be expanded and contracted in the vertical direction.

The lower part of the lower vertical pipe 3 protrudes downward through the concrete base 10, and a water supply pipe 9 is connected to the lower end of the lower vertical pipe 3.

The space between the lower vertical tube 3 and the upper vertical tube 4 is sealed by a sealing member 25 disposed inside the upper end of the lower vertical tube 3.

When water pressure is applied from below, this sealing member 25 is urged upward by the water pressure and acts to seal the space between the upper and lower pipes 4 and 3.

This water guide pipe 2 can be easily bent at least near its upper end 2a (near the upper end of the upper vertical pipe 4).

That is, in this embodiment, the upper vertical pipe 4 is formed of a bendable synthetic resin pipe, so that it can be easily bent.

This is done in order to direct the water from the sprinkler 5 in an appropriate direction when this sprinkler device is installed on a sloped surface such as in a mountainous area, as will be described later.

When the water sprinkler is installed on a flat ground, the tip of the water guide pipe 2 is not bent and is used in a vertical position, as shown in FIG.

The struts 11 are extendable and retractable, each including a lower strut 12 made of, for example, an iron angle member, and an upper strut 13 fixed to the lower strut 12 so as to be slidable in the vertical direction.

The lower support 12 has its lower part embedded in the concrete base 1o and stands on its own.

The lower support 12 and the upper support 13 each have a large number of small holes 14 vertically spaced at appropriate regular intervals (for example, 10 cm intervals).
14... and 15, 15... are formed, and by matching the appropriate small holes 14, 14 of the lower support 12 with the appropriate small holes 15, 15 of the upper support 13, insert a pin or a pin into the overlapping hole. By inserting bolts 16 and 16, the support column 11 can be adjusted and fixed to an appropriate length.

At the tip 11a of the column 11 (the tip of the upper column 13) is a support member 1 for fixing the tip 2a of the water guide pipe 2.
7 is provided so that the angle can be adjusted freely.

This support member 17 includes a main rod 18 having an appropriate length for supporting the tip of the water guide pipe, and an auxiliary rod 1 for fixing the main rod 18.
The tips 18a * 19a of the main rod 18 and the auxiliary rod 19 are fixed with pins or bolts 20, and the base ends 18b and 19b of the main rod 18 and the auxiliary rod 19 are respectively attached to the upper support 13. They are fixedly attached to the formed small holes 15.15 with pins or bolts 21.22 while being spaced apart in the vertical direction.

The base end 19b of the auxiliary rod 19 is fixed to the small hole 15 near the upper end of the upper support 13, and the base end 18b of the main rod 18 is fixed to the small hole 15 located below the small hole 15 to which the auxiliary rod base end 19b is fixed. It is fixed in a suitable small hole 15, and by shifting the fixed position of the main rod base end 18b in the vertical direction, the inclination angle of the main rod 18 with respect to the column 11 can be adjusted to an angle of 0 as appropriate. ing.

The angle θ of the main rod 18 is between the main rod base end 18b and the small holes 15,1.
The angle θ of the main rod 18 can be set accurately if a scale for indicating the main rod angle is attached to each small hole 15, 15, etc. in advance. can.

Further, the base end 18b of the main rod can be secured at an appropriate height near the tip end 11a of the column by another method, such as a string.

Next, to explain how to use the water sprinkling device of this embodiment, when installing the water sprinkling device on an inclined surface such as a mountainous area as shown in FIG. The main rod 18 of the support member 17 at the tip end 11a of the column is also fixed in a state of being inclined by the angle θ in accordance with the angle β of the slope.

In addition, once this water sprinkler is installed in a fixed position, it will not be moved for a long period of time, so the tip of the water guide pipe 2a
There is almost no need to change the angle θ of the nearby bend.

Then, the length of the water guide pipe 2 is expanded or contracted so that the height of the water sprinkler 5 attached to the tip 2a thereof becomes an appropriate height with respect to the height of the trees T, T to be sprinkled with water.

Next, the strut 11 is adjusted to expand and contract along the side of the water guide pipe 2 so that it has almost the same height as the water guide pipe 2,
Tie the water guide pipe 2 to the support 11 at an appropriate number of places with lashing bands 2.
3 and 23, and the water guide pipe tip 2a is also secured by the lashing band 23 to the main rod tip 18a of the support member 17.
The installation work for this sprinkler device is completed by lashing it down.

In this watering device, water supplied from a water supply pipe 9 passes through a water guide pipe 2 and is sprayed onto trees T, T from a nozzle of a water sprinkler 5.

Further, this watering device is used by extending the water guide pipe 2 and the support 11 to increase the height of the watering device 5 as the tree becomes larger (higher).

FIG. 7 shows another embodiment of the support member 17 for fixing the water guide pipe tip 2a.
A base end rod 26 is fixed to the tip 11a of the support 11 by a bolt 28, and a bolt 2 is attached to the tip 26a of the base end rod 26.
It consists of a tip 27 fixed by 9.

By loosening the bolt 28, the base end rod 26 can be attached to the support tip 1.
1a in a vertical plane (A-B direction), and by loosening the bolt 29, the distal end portion 27 can freely pivot in the left-right direction (C-D direction) with respect to the base end rod 26. It is formed to be.

Therefore, in the embodiment shown in FIG. 7, the water guide pipe tip fixing part (the tip of the tip part 27) of the support member 17 can be fixed to the column tip 11a at any angle in all directions.

In this example, the upper vertical pipe 4 is slightly shorter than the lower vertical pipe 3, and when the tree is small, the upper vertical pipe 4 is used with the upper vertical pipe 4 contracted to the maximum with respect to the lower vertical pipe 3. , and use it by pulling it upwards as the tree grows.

Note that in other embodiments, a single flexible synthetic resin hose may be used as the water guide pipe 2.

In this case, use a slightly longer hose from the beginning.
The hose can be pulled upward as needed to accommodate the growth of the tree.

The embodiment shown in FIGS. 8 and 9 shows another method of fixing the lower strut 12 and the upper strut 13. A projection-shaped engagement piece 31 31 that protrudes in the direction is attached by welding or the like, while a large number of holes 32 32 . . By engaging the hole 32 with the engagement piece 31 from the outside and fixing the lower end of the upper support 13 to the lower support 12 with the lashing band 23, the support 11 can be adjusted and fixed to an arbitrary length. I'm trying to do that.

The lashing band 23 used in the embodiments shown in FIGS. 8 and 9 is formed into a circular shape with a size that encloses the upper support 13, the lower support 12, and the water guide pipe 2, as shown in FIG. In addition, the lashing band 23 is welded (reference 36) to the lower end of the upper strut 13 so that when the strut 11 is expanded or contracted, the upper strut 1
3 may be slid onto the lower support column 12.

Further, the securing band 23 may be formed into a square shape as shown in FIG. 11.

In the embodiment shown in FIG. 12, the vicinity of the upper end of the lower support 12 and the appropriate lower position thereof (for example, the lower position by 30C71)
The guide pieces 33, 33 are fixed by welding or the like at two places, respectively, at appropriate intervals from the L-shaped outer surfaces 12a, 12a of the lower support 12, and the guide pieces 33 and the lower support The lower part of the upper strut 13 is inserted into the guide groove 34.34 formed between the outer surface 12a and the tightening bolt 35. attached to the guide piece 33.33.
35, the upper support 13 can be fixed in a state where it is expanded to an appropriate length.

In addition, as shown in FIG. 13, a guide piece 33.33 is formed in the lower part of the upper column 13 side, and its guide groove 34.3
4 into the upper part of the lower support 12 and the upper support 13
The upper support column 13 may be fixed by a tightening bolt 35 attached to the upper support column 13.

The watering device of the present invention can be used not only for forestry, fruit tree cultivation, and agriculture, but also for general industrial purposes that require watering.

Next, to explain the effects of the present invention, the water sprinkling device of the present invention has the following effects.

(1) The support 11 can be expanded and contracted in accordance with the expansion and contraction of the water guide pipe 2, and the upper part of the water guide pipe 2 can also be fixed to the support 11, improving safety.

(2) Since the water guide pipe 2 does not have to be self-supporting, it is possible to use a small-diameter material or a flexible and inexpensive material (for example, a synthetic resin pipe) as the material for the water guide pipe 2. Cost can be reduced.

Furthermore, when a small diameter pipe is used, the amount of drug remaining in the pipe is small, which is economical.

(3) Since the vicinity of the tip 2a of the water guide pipe 2 can be easily bent, the joint member 8 for adjusting the angle of the water sprinkler 5 can be omitted as in the conventional water sprinkler (Fig. 1). Since the joint member 8 is not used, there is no risk of water leakage from the joint member 8 or freezing of water at the joint member 8.

(4) Since the water guide pipe 2 is fixed to the support even near its upper end, the angle of the sprinkler 5 with respect to the ground is always constant even if the support and the water guide pipe are repeatedly expanded and contracted up and down.
