The present invention relates to an underground watering system, and more particularly, to an underground watering system for supplying water directly to a subterranean area when water is supplied to field crops.

As is well known, there are various methods of irrigation, such as hose irrigation, drip irrigation, fountain irrigation, sprinkling irrigation, mist irrigation, furrow irrigation, and underground irrigation.

Hose water is to supply water by using a hose manually, which is the most used in our country. In addition, drip irrigation is a method of drilling a small hole in a plastic pipe or tube and irrigation by making a nozzle or a fine water outlet at the tip of a thin tube connected to the hole to allow water to bleed out in small amounts. In addition, the fountain irrigation is irrigated by spouting water into the hole tube, the sprinkler irrigation is sprinkled by spraying the water using a nozzle, the mist irrigation is a method of irrigation by making the water fine mist with a mist device. Furrow irrigation is a method of supplying water to the furrows in the facility, and underground irrigation is a method of directly supplying water to crop roots with an irrigation pipe embedded in the ground.

All irrigation methods except ground water are used to supply water to the surface, and because water is not consumed directly from the roots, water consumption is increased due to evaporation, which increases the amount of agricultural water used. Done.

A water supply device using such underground water (Korean Patent Publication No. 1987-0000006; name of the invention: automatic water supply device; hereinafter referred to as "quotation invention") is shown in FIG.

As shown, the automatic water supply device 100 is composed of a reservoir 101, a water supply head 102 and a water supply pipe 106 extending therefrom. The water supply head 102 is made of a water-permeable material, the lower end is blocked by a conical end and the water supply tubular portion 103 is inserted into the soil near the crop roots cultivated on the arable land, and made of a waterproof material, the water supply tubular portion ( Head portion 104 connected to the upper open end of the 103 and the water supply pipe 106 is connected to the lower portion of the reservoir 101 having a lower water level than the position where the water supply head 102 is inserted to be supplied with water It consists of a discharge port 105 to be supplied to the head portion 104 of the water supply head 102 via water.

This conventional automatic water supply device is a continuous supply of water in accordance with the pressure difference generated by the water content of the seedling seedlings, the pressure is lowered when the water supplied to the seedlings pot evaporates. Moisture is to move from the reservoir to the seedling pot. Therefore, the water is automatically supplied at all times according to the evaporation of water, which is advantageous in terms of maintaining proper water, but there is a problem in that the plant is inadequate for adaptation to water stress and actually used for crop growth. In addition, this automatic water supply system is expensive equipment, and it is difficult to install many of these expensive facilities in a farming environment where water must be supplied to a large number of crops over a large area. to be.

Therefore, as shown in Figs. 2 and 3, the applicant directly supplies the roots with water, so that the water is supplied to the optimum position corresponding to the growth state of the crop roots to attract the rooting, and the water is effectively applied only to the roots of the crops. Korea Patent Application No. (Underground Watering System) has been proposed for the underground watering system, which promotes growth by allowing water to be absorbed and supplies water to a large number of crops over a large area. In the well-known thing to supply to, the pumping means 203 for supplying the water stored in the water storage tank 201 at a set pressure, and the inlet 213 for the water pumped from the pumping means 203 to the side inflow Is formed and the water pipe 214 is in communication with the inlet 213 is formed downward from the inside and the head portion 211 is formed in the upper portion hitting the 215, and A body having a outlet 219 coupled to the lower part 211 and communicating with the water pipe 214 at the center thereof and communicating with the communication path 217 at the lower end thereof to allow water to flow out to the outside is formed. It is composed of the watering means 210 consisting of a portion 216, the tip portion 221 is coupled to the body portion 216 and formed in a conical shape to facilitate insertion into the ground,

The scale 220 is formed on the outside of the body portion 216 to insert and feed at the optimum position corresponding to the growth state of the crop roots to induce the rooting to the bottom, and the communication path 217 of the body portion 216 is The delay passage 218 is formed to delay the speed of water passing through the communication passage 217 and to raise the temperature of the water.

Therefore, this cited invention attracts the roots of the crops to be rapidly extended downward, thereby promoting growth, preventing cold damage and early harvest, increasing profitability, suppressing the occurrence of weeds, and evaporating water. Due to the small amount of condensation in the house, condensation can be suppressed to minimize the disease. In addition, since water is supplied deeper than the surface layer, the surface layer does not have good quality, and thus, workability such as harvesting, disaster prevention, and rearer movement is good, and the use of agricultural water is drastically reduced to increase water resource saving and growth effect.

On the other hand, the cited invention, since the communication path 217 and the delay path 218 inside the body 216 have to be precisely manufactured with a very small diameter, manufacturing cost of the manufacturing mold is high, and the scale generated during the use process In addition, the foreign matter is attached to the communication path 217, the delay path 218, there is a problem that the water supply is difficult because the pipeline is blocked.
