DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot-water soil for the purpose of evenly dispersing hot water into soil and allowing hot water to penetrate under the soil without destroying the structure of the soil surface. It relates to a disinfection device.

[0002]

2. Description of the Prior Art Conventionally known soil disinfection involves inserting the tip of a parallel nozzle into the ground or spraying water from many parallel nozzles onto the ground.

[0003]

The above-mentioned conventional spraying from a hot-spray nozzle has problems such as poor permeability due to the destruction of the structure of the soil surface depending on the type of soil, and poor efficiency of temperature rise. Was.

In addition, the method of inserting the watering nozzle into the soil has a problem that the distribution of hot water tends to be uneven and it is difficult to keep the whole soil at a predetermined high temperature.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a sprinkler nozzle provided on a sprinkler pipe (may be blown out from a mere hole).
With a cover plate, and the hot water blown out from the water spray nozzle is allowed to flow down to the ground, enabling uniform spraying and efficient penetration into the soil without destroying the structure of the soil surface. is there.

That is, according to the present invention, a sprinkler nozzle is installed in parallel on one side of a sprinkler pipe, and the sprinkler nozzle is covered with a cover plate, and the lower part of the cover plate is inclined toward the ground for flowing down the sprinkler. This is a soil disinfection device using hot water, characterized in that the disinfection device is a hot water disinfection device. Further, the cover plate is characterized in that it covers the upper part of one side of the sprinkler pipe and the entire nozzle.

In the above, the inclined plate of the cover plate is at an angle of 30 to 45 degrees with respect to the ground, and the tip of the inclined plate is preferably in contact with the ground or at a gap of 2 to 3 cm.

The material of the cover plate is not particularly limited,
A stainless steel plate or a heat-resistant synthetic resin plate which does not deform, alter, or corrode with hot water (90 ° C. to 100 ° C.) and soil components can be considered.

The shape of the cover plate and the gap with the ground are not particularly limited, and it is sufficient that the hot water sprayed from the nozzles is evenly sprayed without strongly hitting the ground surface.

As the sprinkling pipe, a conventionally used pipe can be used as it is. However, for the hot water spray nozzle, the interval is determined according to the spraying condition.
m to 5 cm.

After the above-mentioned hot water spraying, the surface of the soil is covered with a vinyl sheet or the like, and the soil of 20 cm to 30 cm from the surface is kept at 55 ° C. or higher for a certain period of time to improve the sterilizing and insecticidal effects. In the case of non-uniformity, depending on the sprinkling condition, the temperature may be as high as 55 ° C.
In some cases, the temperature cannot be kept above ℃. This is presumed to be due to the temperature of the hot water, the amount of the hot water and the uniformity of the hot water. Although the temperature and the amount of the hot water can be easily controlled, it is difficult to control the uniformity of the hot water and it is difficult. However, if the distribution of the flow of the hot water is uniform, it will penetrate evenly into the soil, facilitating uniform heating.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a sprinkler nozzle with a sprinkler nozzle arranged in parallel on a sprinkler pipe at a predetermined interval, and covers the sprinkler nozzle with a cover plate, and a lower portion of the cover plate faces the ground for flowing down the sprinkler. To make the water come out from the spray nozzle evenly,
Also, it is a hot water soil disinfection device that allows hot water to penetrate into soil without destroying the structure of the soil surface.

[0013]

An embodiment of the present invention will be described with reference to the drawings.
Sprinkling nozzles 2 and 2 are installed in parallel on a sprinkling pipe 1 connected to a discharge port of a boiler (not shown). One side of the upper end of the cover plate 3 having an inverted U-shape is fixed to the upper part of the spray pipe 1 to cover the spray nozzles 2 and 2, and the lower plate 3 a of the cover plate 3 faces the ground surface 4. At an angle of about 40 degrees, and its edge 3b is spaced from the ground surface by a distance of 2 to 4 cm (h).
Is provided. In the above embodiment, the hot water blown out from the spray nozzle 2 as shown by arrow 5 collides with the vertical plate 3c of the cover plate 3 and is dispersed, and then flows down along the lower plate 3a as shown by arrow 6. Then, it falls on the soil surface as shown by arrow 7 and penetrates into the soil as shown by arrow 8.

Therefore, if the water volume is adjusted to an appropriate value (200 to 300 l / m ² ), the soil 30 cm deep from the surface of the ground can be heated to 55 ° C. or higher.

In the above, the hot water spouted somewhat unevenly from the sprinkler nozzle 2 is evenly distributed by the vertical plate 3c and the lower plate 3a, and penetrates into the soil in a substantially constant amount.

[0016]

According to the present invention, the sprinkling nozzle is covered with a cover plate to distribute the sprinkling water evenly, and the hot water permeates downward without destroying the structure of the soil surface, so that the soil is evenly heated. Then, hot water can be deeply penetrated into the soil and kept at a predetermined high temperature to achieve a sterilizing and insecticidal effect.
