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, so conventional watering equipment for forestry or fruit cultivation uses the tip of a vertically long water guide pipe 20 as shown in FIG. A sprinkler 5 is attached to the portion 20a via an angle adjusting joint member (spherical joint member) 8.

The water guide pipes 20 each include a lower vertical pipe 22 made of a steel pipe or an aluminum pipe, and an upper vertical pipe 21 that is slidable in the vertical direction with respect to the lower vertical pipe 22. By sliding it in the vertical direction and fixing it with the stopper device 6, the installation height of the sprinkler 5 attached to the water guide pipe tip 20a (the upper end of the upper vertical pipe 21) can be adjusted as appropriate. It has become.

As shown in Fig. 2, the spherical joint member 8 for angle adjustment is used to tilt the water sprinkler 5 in the right and left (or front and back) direction by an appropriate angle α when installing the water sprinkler on a sloped surface such as in a mountainous area. This is to enable water to be sprinkled.

This conventional water sprinkling device A is supported by fixing the lower vertical pipe 22 to a fixed-length support 7 that is erected and fixed near the side of the water guide pipe 20.

The height of the support 7 is formed to be approximately the same as the height of the lower vertical pipe 22, and the support 7 is formed near the upper end of the lower vertical pipe 22.
It is tied near the top of the.

However, this conventional water sprinkler A has the following problems.

(1) Since only the lower vertical pipe 21 of the water guide pipe 20 is fixed to the support 7, the upper vertical pipe 21 is unstable and vibrates due to the water pressure and impact of the water sprinkler 5, resulting in poor water distribution uniformity. .

In particular, when the upper vertical tube 21 is elongated, it becomes even more unstable.

(2) The upper and lower vertical pipes 21 and 22 of the water guide pipe 20 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 by the angle adjustment joint member 8 so as to be almost upright with respect to the inclination direction of the ground, and then the upper vertical pipe 21 is extended upward. At this time, the upper vertical pipe 21 is moved left and right. In many cases, the water sprinkler 5 rotates and 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, when used by farmers etc. Because they were expanded and contracted without care, they were sometimes not used in the proper condition.

The present invention was made in order to improve the conventional problems as described above, and the purpose is to provide a watering device that can be manufactured at low cost and that can be installed stably. It is something to do.

Hereinafter, the watering device of the present invention will be explained based on the illustrated embodiment. The watering device B of the embodiment shown in FIG. 3 is used for forestry or fruit tree cultivation, and the watering device B is A water sprinkler 5 is attached to the tip 2a of a vertically long water guide pipe 2, which is formed by attaching an upper vertical pipe 3 to the vertical pipe 4 so as to be extendable and retractable, and a water sprinkler 5 is attached to the water guide pipe 2 at a position near the side of the water guide pipe 2. A self-supporting column 11 that can be expanded and contracted in the vertical direction is disposed along the column, and the water guide pipe 2 is secured to the column 11 so that the water guide pipe 2 can be stably erected.

The upper vertical pipe 3 of the water guide pipe 2 is formed of a TTM resin pipe such as a polyethylene pipe or a metal flexible pipe having appropriate hardness and flexibility, and the lower vertical pipe 4 of the water guide pipe 2 is made of a metal flexible pipe or the like. It is made of metal pipes.

The diameter of the lower vertical tube 4 is larger than that of the upper vertical tube 3, and the lower portion of the upper vertical tube 3 can freely slide into the upper portion of the lower vertical tube 4. The water guide pipe 2 is inserted so that it can expand and contract in the vertical direction.

Further, the lower part of the lower vertical pipe 4 is made of a concrete base 1.
0 and protrudes downward, and a water supply pipe 9 is connected to the lower end of the lower vertical pipe 4.

The space between the lower vertical tube 4 and the upper vertical tube 3 is sealed by a sealing member (not shown) disposed inside the upper end 4a of the lower vertical tube 4.

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

The water guide pipe 2 can be easily bent at the upper end 2a of the water guide pipe (near the upper end of the upper vertical pipe 3).

That is, in this embodiment, the upper vertical pipe 3 is formed of a synthetic resin pipe having appropriate hardness and flexibility, or a metallic flexible pipe, so that the vicinity of its upper end can be easily bent. There is.

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

When the water sprinkling device B is installed on a flat land, it is used with the water guide pipe tip 2a and its vicinity kept in a vertical state without being bent, as shown by the chain line in FIG.

The column 11 is composed of an L-shaped lower column 13 and an L-shaped upper column 12 that slides vertically along the lower column 13.

The lower end portion of the lower support 12 is embedded in the concrete base 10 and stands on its own.

The upper support 12 and the lower support 13 each have a large number of small holes 14, 14, 14, 15,
15... are formed, and the small holes 14, 14 at appropriate positions in the upper support column 12 are aligned with the small holes 15, 15 at appropriate positions in the lower support support 13, and a pin or bolt is inserted into the overlapping hole. 16. By inserting 16, the support column 11 can be adjusted and fixed to an appropriate length.

A support member 17 for supporting the water guide pipe tip 2a is provided at the tip 11a of the column 11 (the tip of the upper column 12) so as to be adjustable in angle.

As shown in FIG. 4, this support member 17 has a proximal rod 26 fixed to the tip 11a of the column 11 with a bolt 2B.
The tip 2 is fixed to the tip 26a by a bolt 29.
It is composed of 7.

The base end rod 26 can be attached to the support tip 1 by loosening the bolt 28.
1a, in a plane perpendicular to A-B in FIG. 4, and by loosening the bolt 29, the distal end 27 can pivot in the left-right direction (C-direction) relative to the proximal rod 26. It is designed to be flexible.

Therefore, the support member 17 has a water guide pipe tip fixed portion (tip portion 2
7) can be fixed to the support tip 11a at any angle in all directions.

In this embodiment, the upper vertical pipe 3 is slightly shorter than the lower vertical pipe 4, and when the tree is low, the upper vertical pipe '3 is used with the upper vertical pipe '3 fully contracted relative to the lower vertical pipe 4. , and use it by pulling it upwards as the tree grows.

Next, we will explain how to use the water sprinkler B of this embodiment.
When this water sprinkler B is installed on a slope such as a mountainous area as shown in FIG. The nozzle angle adjustment device 17 of the tip end portion 11a of the support is also fixed in a state of being inclined by an angle θ.

Note that once the water sprinkler device is installed in a fixed position, it is not moved for a long time, so there is almost no need to change the angle θ of the bending portion near the tip portion 2a of the water guide pipe.

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

Next, the strut 11 is adjusted to expand and contract along the water guide pipe 2 so that it has almost the same height as the water guide pipe 2, and the water guide pipe 2 is secured to the support 11 at appropriate locations with lashing bands 23.2.
3, and the water guide pipe tip 2a is also tied to the tip 27 of the support member 17 with the lashing band 23, the installation work of the water sprinkler B is completed.

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 from a nozzle of a water sprinkler 5.

In addition, this water sprinkler B is used by extending the water guide pipe 2 and the support 11 to increase the height of the water sprinkler 5 as the tree grows.

The watering device B of the present invention can be used not only for 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 sprinkler B 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, a small diameter pipe or a flexible and inexpensive synthetic resin pipe can be used as the material for the water guide pipe 2, reducing the overall cost. can be done.

Moreover, when a small diameter pipe is used, the amount of chemical solution remaining in the pipe is small, which is economical.

(3) The vicinity of the tip 2a of the water guide pipe 2 is supported by a support device 17 consisting of two mutually bendable base end rods 26 and a tip 27, so that it can be easily bent, which is different from the conventional water sprinkling device. (Fig. 1), the expensive angle adjustment joint member 8 can be omitted, and since the joint member 8 is not used, there is no risk of damage to the joint member 8 or water leakage due to freezing, etc. Things will go away.

(4) The water guide pipe 2 also has a support 1 near its upper end.
1, the angle of the sprinkler 5 relative to the ground is always constant even if the support 11 and the water guide pipe 2 are repeatedly expanded and contracted up and down during work.
