Description

[Detailed Description of the Invention] The present invention relates to a watering device that can spray water in the form of a mist when watering a seedling box.

Generally, when watering a seedling box, a pipe with irrigation holes drilled at regular intervals is used, and the seedling box is moved directly under the pipe while watering. The water that comes out falls in the form of strings like rainwater, so the water pressure causes the soil for raising seedlings to roll up, creating streaks of water on the surface of the bed for raising seedlings, making the surface of the bed for raising seeds uneven, and overwatering areas and areas not being irrigated. This resulted in uneven irrigation.

The present invention relates to an irrigation device which solves the above-mentioned drawbacks and is capable of uniform irrigation using atomized shower water, and its configuration will be described in detail with reference to the accompanying drawings as follows.

Circular diffusion recesses 2 are formed at regular intervals in the pipe 1, and a small-diameter irrigation hole 3 is placed opposite the bottom end of the circular diffusion recess 2 so that the center diagonal line 4 intersects at the opening of the circular diffusion recess 2. Irrigation holes facing the are diagonally drilled with a V-shaped cross section.

The drawing shows a case where two irrigation holes 3 are drilled, but four irrigation holes may be added.

In the figure, 5 is a seedling box, and 6 is a water hose.

In the present invention, as described above, the irrigation holes 3 are arranged opposite to the bottom end of the circular diffusion recess 2, and the opposing irrigation holes are arranged in a V-shaped cross section so that the center diagonal lines intersect at the opening of the circular diffusion recess. Because the holes are diagonally drilled, the water discharged from the irrigation hole 3 crosses and collides with the opening of the circular diffusion recess 2 as shown in Fig. 3, and the direction of diffusion is restricted by the circular diffusion recess 2, so that water can be watered. The water vigorously discharged from the holes 3 is dispersed in an extremely good condition and becomes a mist shower.

If there are two irrigation holes 3, the water will be diffused in a nearly elliptical shape, and if there are four, the water will be diffused in a circular shape.

In this way, since watering is performed using a soft mist shower, the seedling bed will not be rolled up or streaks of water will be formed, and water will be uniformly applied.

Therefore, since it can perform stable irrigation, it becomes an excellent irrigation device that promotes the growth of seedlings.

Furthermore, this device has a simple structure of simply drilling a recess and a hole in the pipe, so it can be mass-produced and can be provided at a low price. It has excellent practical effects and can also be used as a watering nozzle for gardening.
