Description

OBJECT OF THE INVENTION

The invention, as stated in the present specification, refers to a multipurpose irrigation device located for agricultural crops, which contributes to the function to which several advantages and novelty characteristics are intended, which will be described in more detail. forward and that represent an improved alternative to other systems currently known for the same purpose.

More particularly, the object of the invention is focused on a device whose purpose is to provide a localized and movable irrigation system that, being applicable to almost any type of agricultural crop, is especially 'Jentajoso' for large crop areas, being, thanks to its innovative structural design, suitable for both wetting and drip irrigation, as well as for dispersion irrigation, and for intensive cultivation as well as for extensive cultivation, whether monoculture or mixed cultivation, since it adapts to different plot sizes and types and size of grooves, also providing other economic and practical advantages.

FIELD OF APPLICATION OF THE INVENTION

The scope of the present invention is framed within the agricultural sector,

focusing on the technical field of industry

BACKGROUND OF THE INVENTION

As is known, the main existing irrigation systems so far are basically three:

Irrigation

by flood or r ~ ego to blanket,

consistent

in leave to run he Water by grooves

previously

made in he culture. Is he method

used

historically, that yet be use in countries

underdeveloped, or where water is very abundant.

-

Sprinkler irrigation or ~ artificial rain ", which appears, in a massive way, in Spain in the early sixties. It consists of directing the water, under pressure, by pipes from which sprinklers emerge that disperse water in small drops. Within this modality, variants such as coverage are contemplated, in which a pipe network covers the entire plot, watering it by sectors, by opening and closing certain stopcocks. Another variant is the so-called ~ Pivot ", in which the sprinklers are mounted in a raised pipe on a structure with driving wheels that move radially around an axis, watering a circularly shaped plot, with others moving longitudinally. Another variant of sprinkler irrigation is irrigation by water cannon, which becomes a large sprinkler that is fed by an elastic pipe wound in a large reel.

-Finally there is drip irrigation, in which water is circulated, also under pressure, by

a network of pipes that are located next to the plants where they deposit the water drop by drop until a moisture stain is generated. This last system can be considered the best, given the saving of water and other advantages, but it suffers from a serious inconvenience, since it is only applicable in intensive crops, or in

applications

where he system be may leave installed

permanently,

viticulture, wooded etc. So, by

example,

for a plot from 10 he has in grooves

established at a distance of 50 cm. in addition to abundant tubes and stopcocks, 2,000 rolling tubes of 100 meters each would be necessary, which would also have to be installed and then collected and stored, which is absolutely uneconomic

Thus, the device that is claimed is intended to develop a new multipurpose irrigation system that allows to combine the advantages of existing systems and avoid their drawbacks, it must be noted that, at least by the applicant, the existence of any another device or invention of similar application that presents technical, structural and constitutive characteristics similar to those presented by the polyvalent irrigation device located for agricultural crops that is recommended herein and whose characterizing details are conveniently included in the final claims that accompany the present descriptive report of it.

EXPLANATION OF THE INVENTION

Specifically, what the invention proposes is an irrigation device designed to be able to

move along the grooves of a plantation

or seeded, and that, formed by a set of structural pipes as a comb, allows water to be carried from a primary pipe that is fed in a conventional way to a series of cannulas distributed to regular spaces in which tubes that descend to almost the ground.

For this and more specifically, the device is configured, essentially, from a primary pipe, which is as long as the plot to be irrigated and as thick as to accommodate, as a minimum, the necessary water flow, under the that are coupled, longitudinally and parallel to it, several secondary pipes, being connected to each other by means of a connection tube with a stopcock to control the passage or not of the water and flow of the same.

The secondary pipes, in turn, have, in their lower part, with multiple outlet cannulas, to which, as appropriate, either a descending tube of elastic or semi-rigid material is attached, which branches into two narrow branches and elastics, either closed with a plug, or a nozzle is attached to disperse the water.

The whole set is supported by driving wheels through which the entire system moves along the rows of the sowing, in both directions.

The advantages of the recommended device, compared with the characteristics of other irrigation systems, are multiple, being able to stand out as more relevant, both in the economic and ecological aspect, the following:

up to 90%, since you only need to put the water flow at the height of the primary pipe (normally about 2 meters), from which the water descends by gravity, while conventional sprinkler and drip systems They require a pressure of between 2 Kg./cm2 to 5 Kg./cm2.

Water economy around 20% -30% compared to sprinkler systems.

Lower cost of facilities than in any of the other systems, since much smaller pumps and products that already exist in the market are used at very low cost.

-

Good adaptability to the different shapes and sizes of the plots, unlike the Pivot system, which can only irrigate 75% of most plots.

-

Easy possibility of automation.

-

Possibility of maintaining the installation permanently, as in the Pivot, or easily disassemble and store it, and even use it in a different plot.

-

It does not cause damage to the crop such as the circular pivot, whose wheels leave a deep mark.

Important fertilizer savings, as this system deposits it on the roots of the plant. Spray systems spread it throughout the surface, where the roots do not reach and also above the leaf surface, which implies loss of

for harming the leaves.

The system maintains its characteristics, regardless of the prevailing wind, while in sprinkler irrigation it can be a severe inconvenience.

-Absolute

accessibility from the users to the

system,

yet when he team East in functioning,

be arrives to he in ground dry Y to a height

easily accessible and manipulable. In sprinkler irrigation, you step on mud.

-

Simplicity of operation, since all the driving wheels rotate at the same speed, unlike the circular Pivot whose wheels rotate progressively to measures that move away from the axle, as well as the sprinklers increase in flow.

-

Easy regulation of the flow in each of the secondary pipelines, through the interposed stopcock, being able to even differentiate a flow from others, which allows to irrigate mixed crops.

-

Adaptability at different distances between rows.

Possibility of watering similarly to spray equipment (arable crops, fodder etc.) by replacing the downspouts with fan-shaped nozzles in all outlet cannulas, creating a water curtain.

It does not require water filtration as in drip procedures.

-

Less leaching effects.

Lower incidence of cryptogamic diseases.

-

It covers a wider range of irrigable crop types.

-

By not watering on the leaves, it allows the use of worse quality waters without harming the plant.

In view of the foregoing, it is noted that the described polyvalent irrigation device located for agricultural crops represents an innovation with characteristics unknown until now for that purpose,
