Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sprinkling pipe and a sprinkling device for equalizing the amount of hot water discharged from each nozzle.

[0002]

2. Description of the Related Art Conventionally, various structures are known in order to obtain a uniform amount of water spray from a water spray pipe having a plurality of nozzles. For example, an invention in which the opening area of each nozzle is associated with each water pressure (JP-A-7-100407) or an invention in which the angle of the nozzle is devised (JP-A-7-51599) is proposed. .

[0003]

In the above, when the nozzle opening area is changed, if the water pressure fluctuates, it is not always quantified, but there is a problem that the manufacturing tends to be complicated or labor is required. It was

Next, when the angle of the nozzle is changed, even if water can be injected evenly under a constant water pressure, there is a problem that when the pressure fluctuates, it becomes uneven. In addition, drilling at a design angle at the time of manufacturing not only requires a skillful technique, but also has a problem that it is difficult to improve manufacturing efficiency.

[0005]

According to the present invention, a normal pressure fluctuation (for example, 1 to 2 kg / cm) for hot water supply is obtained by deeply thrusting a nozzle cylinder into a pipe body (for example, thrusting beyond a radius of the pipe body). ^Even within ² ), we succeeded in keeping the amount of hot water sprayed from each nozzle almost constant.

That is, according to the present invention , the sprinkling pipe main body can be rotated.
Noh attached arm and the arm fixed to form a supporting rod.
The nozzle tube is sprinkled on the sprinkling pipe body having a supporting means.
In addition to plunge more than half the inner diameter of the hot water pipe,
It is characterized in that the hot water supply pipe is connected to the hot water supply pipe.
It is a water sprinkler .

Next, the present invention supports the sprinkling pipe main body.
Nozzle is attached to the main body of the sprinkling pipe that has the means for supporting the guide boat.
Install the tube into the hot water pipe more than half of the inner diameter.
And that the hot water supply pipe was connected to the hot water supply pipe.
Is a water sprinkling device .

In the above invention, the rush length of the nozzle and
Although the relationship with the inner diameter of the pipe body differs depending on the diameter, length, inner diameter and length of the nozzle, etc.
The diameter of the sprinkling pipe is 40 mm that seems to be practically uniform.
˜50 mm, length 2000 mm (to send hot water from the central part), and nozzle inner diameter 1 to 3 mm, if the plunge length of the nozzle cylinder is ½ or more of the inner diameter of the sprinkling pipe, The difference between the amount of hot water sprayed from the nozzle and the amount of hot water sprayed from the left and right end nozzles is 5% or less, and the influence of the amount of hot water sent is small.

However, if the difference in the amount of sprinkling water for soil disinfection is 10% or less, the objective can be sufficiently achieved.

In order to kill all pathogenic bacteria in the soil of greenhouses, hot water of 90 ° C to 100 ° C is sprinkled on the soil surface and covered with a vinyl sheet. The soil covered with the vinyl sheet is 60 ° C or more. By holding it for 20 minutes or longer, many weed seeds, many viruses, soil pests, nitrifying bacteria, filamentous fungi and many other pathogenic bacteria are killed. Therefore, depending on the depth of the soil, for example, 20 from the surface
It is necessary to have a hot water temperature and a hot water amount that can be maintained at a temperature of 60 ° C. or higher for 20 minutes or longer up to a depth of 30 cm to 30 cm, and it is sufficient if there is uniformity enough to secure the required hot water amount.

In the above description, the reason why the amount of rush of the nozzle cylinder is ½ or more of the inner diameter of the main body pipe is that even if the amount of hot water supply is uneven, the pressure at the nozzle outlet can be balanced so that the amount of hot water sprayed is substantially uniform. To become. When the amount of rush is less than one half of the inner diameter of the main body pipe, the pressure balance near the nozzle is likely to be broken, so at least the nozzle pipes on the left and right of the connecting pipe (right and left of the pouring position of the hot water) are connected to the main pipe. you longer than one-half of the inner diameter.

Although the present invention has been described with reference to a sprinkling pipe, a sprinkling pipe is also the same and has the same technique.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION An object of the present invention is to make uniform the amount of hot water discharged from the nozzle holes when a plurality of nozzle holes having the same diameter are formed in a long pipe and hot water is supplied from one side. It is a thing.

In order to achieve the above object, when the nozzle tube is inserted into the sprinkling pipe main body, the nozzle cylinder is made to project to 1/2 or more of the inner diameter of the pipe main body.

Next, when the branch pipe is connected to the hot water supply pipe via the connection pipe, the nozzle pipe of the branch pipe is also installed by rushing to 1/2 or more of the inner diameter of the branch pipe so that the amount of hot water blown out from each nozzle hole is equalized. It can be the amount of hot water.

Embodiment 1 An embodiment of the present invention will be described with reference to FIGS. One side long pipe 1a of the rectangular pipe body 1
2, the nozzle tubes 2 and 2 are installed at a predetermined interval so as to protrude by 1/2 or more of the inner diameter of the long pipe 1a, the hot water supply pipe 3 is connected to the central portion of the other side long pipe 1b, and the long pipes 1a and 1b are connected to each other. It connects with the connection pipes 4 and 4. A support rod 6 is connected to the long pipe 1b via arms 5 and 5,
The arms 5 and 5 and the long pipe 1b are rotatably attached to form a sprinkling pipe 20.

In the above embodiment, when pressurized hot water is fed into the hot water supply pipe 3 as shown by arrow 7 in FIG. 1, it flows as shown by arrows 8 and 9 into the long pipe 1a, and then the nozzle tube 2 It flows through the central hole as shown by arrow 10 and is sprinkled on the ground 12 as shown by arrow 11.

In the above, the water pressure in the long pipe 1a is
Since it is relaxed and adjusted by the nozzle cylinder 2, the connecting pipe 4,
Regardless of the distance from 4, almost equal pressure can be maintained. The pipe body 1 is supported by a support rod 6 via an arm 5 as shown in FIG. 2, the pipe body 1 is obliquely supported on the ground, and hot water is blown onto the ground surface. Therefore, even if the arm 5 and the long pipe 1b are rotatable, it is desirable that they can be fixed at a predetermined angle by screwing or the like.

[0019]

[Embodiment 2] An embodiment of the present invention will be described with reference to FIG. A branch pipe 14 is connected to the hot water supply pipe 12 via a connection pipe 13 in parallel with the hot water supply pipe 12, and the nozzle pipe 15 is connected to the branch pipe 14 by 1 / (1) of the inner diameter of the branch pipe 14.

It is sprinkled with water like 9.

Nozzle cylinders 15 on both sides of the connecting pipe 13.
It is preferable that a and 15b are made to penetrate longer than 80% or more of the inner diameter of the branch pipe 14. This is because when the inflow amount from the connecting pipe 13 can sufficiently cover the outflow amount of all the nozzle cylinders, the pressure difference due to the position of the nozzle cylinder does not occur, but when the inflow amount becomes equal to or less than the pressure difference, the pressure difference occurs. The amounts may be uneven.
