UNDERGROUND WATER INJECTION DEVICE FOR IRRIGATION

AGRICULTURAL

TECHNICAL SECTOR

The present invention belongs to the agricultural technical equipment sector and more specifically to the irrigation systems and infrastructures of agricultural crops.

Its main purpose is an underground irrigation device that deposits water and fertilizer in the subsoil, making it more accessible to the roots and maximizing the use of water, as opposed to the greater risk of evaporation associated with surface irrigation systems.

BACKGROUND OF THE INVENTION

Water is a scarce natural resource whose consumption must be optimized. At present, the operation of irrigation and fertilization in agriculture is carried out, mostly, by irrigation located on the surface by means of adjustable drippers that dose the amount needed for the plant. This modality has allowed a better use of irrigation water but there are still aspects that can be improved, such as:

- a part of the water evaporates without being used up.

- The roots tend to grow towards the wet surface, rooting little in the subsoil. - Drippers tend to deteriorate and become clogged due to the weather and the action of small animals.

- The fauna that feeds from the water of said drippers is exposed to the risk of poisoning and death due to the ingestion of chemical products diluted in it.

Underground irrigation represents a valid alternative system to overcome these deficiencies.

In the state of the art there are several types of underground irrigation devices that have been improving in efficiency and simplicity making them more competitive. There are systems in which practically all of the irrigation network runs buried under the surface. While others more recent they combine the channeling in surface with localized devices that, drilling the earth, allow the underground irrigation. In all cases, the risk of plugging due to soil dirt is shared as a common problem. Inconvenient that, if it were to occur, it would be difficult to detect simple sight since irrigation occurs underground. It is convenient to create a new underground irrigation device that, incorporating the advantages offered by existing ones, provides a solution to control possible blockages that prevent the proper functioning of it. The aim of the present invention is to improve the state of the art by introducing an innovation, nonexistent in the devices known up to now, focused on facilitating the verification with the naked eye of the correct flow of water or of the existence of obstructions in the underground irrigation device. . The state of the art has several underground irrigation devices that, being similar in fundamental, are distinguished by technical nuances such as those published in ES1056459U, ES1064884U and ES2315116A1.

EXPLANATION OF THE INVENTION

The agricultural underground irrigation device that is recommended consists of a transparent hemispherical body with a flat base that rests, like a dome, on a tube of variable length, depending on the depth to which the water is to be deposited, introduced in the subsoil and perforated said tube in its lower half with several holes to evacuate the water.

In the tube a hose connected by its upper end to the transparent hemispherical body is introduced through a hole made in its flat base. In this way, the interior of said transparent dome is communicated with the interior of the tube that supports it. The length of the hose should be sufficient so that when introduced into the tube it contributes to guarantee the stability of the hemispherical body avoiding its detachment.

The diameter of the hose will vary depending on the flow of water that is to be supplied to the plant. The hemispherical body communicates in turn with the general distribution network of irrigation water by means of another hose than the previous one, which, introduced by an additional hole made in its flat base, is connected to the aforementioned irrigation main pipe. Said hose will be of diameter and material similar to the previous one, although it will be feasible to attach to it the traditional dripper system to regulate the water supply when the orography of the land causes pressure differences in the distribution network. In this way it is possible to visualize how the water penetrates through a hose in the hemispherical compartment and follows its course through the other hose that transports it to the pipe inserted in the earth.

To avoid possible clogging, it is advisable, when installing the device, to open a gap in the earth that offers slack when placing it inside reducing the pressure and contact of the earth on it.

However, in case of plugging the transparent hemispherical body would allow to check with the naked eye if the water is not flowing correctly and if it is stagnant.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, an assembly of drawings is included as an integral part of said description, in which the illustrative and non-limiting character has been represented. following

PREFERRED EMBODIMENT OF THE INVENTION

The device (1) of underground injection of water for agricultural irrigation consists of a tube that is inserted into the subsoil (2) drilled with holes in its lower half (3). It also has a hemispherical and transparent body (4), a hose (5) that carries water from inside the hemispherical body to the inside of the tube (1) and another hose (6) that carries water from the general network of distribution (7) to the interior of the hemispherical body (4).

The operation of the device is as follows.

Agricultural irrigation is distributed mainly through a network of pipes (7), normally made of polyethylene, located on the surface and close to the cultivated plants.

⁽ 8 ⁾

To ensure efficient and efficient use of water, depositing it near the root (9) and reducing the risk of partial evaporation, the device (1) is installed by introducing the tube (2) into a hole made in the ground at the desired depth . To prevent possible plugging, it is advisable to perforate the floor so that the tube (2) penetrates it with some slack. The hemispherical body is deposited on the upper end of the tube (2) located outdoors. transparent (4) so that the hose (5) is inserted in the tube (2) communicating its interior with the interior of the hemispherical interior (4) into which it penetrates through a hole made in its flat base. Another hose (6) is the one that communicates the hemispherical body (4) with the pipeline of the general distribution network of the irrigation allowing the entry of water that will circulate throughout the device (1) that irrigates the plant underground. The diameter of the hoses will depend on the water supply needs of each crop. In any case, the hose (6) admits the coupling of a traditional dropper (10) if the relief of the farm advises it to regulate the contribution of water to the pressure differences caused by the unevenness of the land. Finally, the plant is fed with the water necessary for its development but with the added advantages offered by the underground irrigation of:

- Facilitate root access to water and fertilizer that is deposited nearby in the subsoil.

- Avoid partial evaporation of water from irrigation on the surface. So you save water by saving the cost.

- The possible poisoning of animals that drink water from surface drippers by ingesting water mixed with chemicals harmful to health is prevented.

It is a device of confection and installation of great simplicity that contributes to the responsible and sustainable consumption of water in the agricultural sector as a scarce natural resource.
