DESCRIPTION

Drip system for irrigation

state of the art

At present there are various models of drippers and dripping systems and it would be very prolific to make references to as many as they exist. The one presented is different because the inventor has not seen anything in any writing or in any vade mecum of drip systems.

Explanation of the invention

It is a dropper that is external to the pipe and is attached to it, it admits many designs and variants: The material with which it is made can be rigid or very flexible such as metal, rubber, porcelain, various plastics, etc. opaque, transparent, or translucent. - In the dropper: Fig. 1.-Dimension L is the length. The dimension a is that of the arc of circumference that surrounds the pipe. Fig.2.- It is the sketch of the drawing of the small channels (several examples) through which the water circulates from when it leaves the hole in the pipe until it drips from the free end. Fig.3. The exterior design shall be smooth enough to prevent snagging. In order to couple it to any size pipe, it can be made of flexible material, so the same dripper can be used with different pipe diameters or flat surfaces so that it can carry some glue or other fastening procedures.

The water circulates between the outer wall of the pipe and the internal face of the dripper through the channels existing on said internal face Fig.2.

The coupling or embracing of the dripper to the adductor pipe is achieved in various ways, some are shown. Fig.3. In the design of the dripper there are two differences: that the arc a_does not pass the diameter of the pipe (assumption 1) or that it passes it (assumption 2. Fig1 A-B).

- In course 1, it is fastened (Fig.3) with any type of clamp, hook, skewer, elastic band, glue, etc.

- In case 2, it is fastened alone, without any element (Fig.1) and is adapted by pressure with the fingers, but the fastening can be reinforced with systems indicated in Fig.3, although they are not necessary when watering with little pressure .

The drippers have a hole in the shape of a frustoconical, conical, pyramidal, etc. that allows the coupling of other accessories: dripper with microtubes, diffusers, sprinklers, etc. (Fig.4). the foramen e is located anywhere (11, 12, 13, 14) along the canaliculi (Fig 5). They also have a blind area that closes the passage of water.

Advantages over already patented systems: (Fig.6).

The models of already patented internal drippers, with a split pipe for their introduction, imply that the dripper performs the functions of holding, conducting and losing load, so the plastic material, normally due to its lower cost, has to have a certain consistency and thickness. With this type of dripper, the pipe does not split, it is pierced and due to its design it does not perform the functions of holding and conducting the water, it only performs the loss of pressure, therefore it requires less material and therefore will have a lower manufacturing cost.

The size of the interior channels will be large, and with many changes in the direction of the water, the loss of load is achieved by these continuous changes, which allows the section to be increased, avoiding problems of blinding or clogging by particles or saline precipitation. The length of the little channels is designed as long as desired (Fig.2.) As the pipe does not break due to the external drippers, it can be pulled without fear of it coming loose, when they put internal drippers (and the pipe breaks) they go with a lot of pressure or they "weld", have the very serious drawback that they are difficult to disassemble (sometimes impossible), for cleaning in case of clogging or clogging by salts from the dripper, which cancels its function.

By not introducing anything into the pipe to take the water, the loss of load in the transport is clearly lower since there are no obstacles in its circulation, (Fig. 5), which allows the use of longer irrigation adductor pipes (greater area irrigation system with the same installation and driving power). Smaller section in the pipes (lower installation cost). Less energy consumption for its operation.

The system allows the flow rate of each dripper to be varied easily and independently by simply moving its position over the "water intake" hole, thus varying the path of the water through the canaliculi (the head loss is a function of said path ) or close the passage, it can be irrigated along the branch with the desired flow in each dripper, compensating for the differences in unevenness of the terrain, which avoids movements, or terrain with a lot of inclination, lengthening the lengths of the main and secondary branches.

The system allows alternating the plants with very different irrigation needs along the same branch, watering only with the drippers that are unnecessary and/or being able to open them or vary their number and flow, adapting the irrigation to the growth of the plant or that they work when it is desired that the roots grow in a certain direction, and all this without altering the general installation (position of the adductor pipe).

Putting the dripper is simple, the pipe can be perforated at regular distances from the factory or perforated by the user, with a slight pressure of the finger the flow rate can be placed and adjusted and with a pinch it is removed, in case the dripper is clogged it separates and the very jet that comes out of the hole is used to clean it; it is not necessary to stop the irrigation shift to clean the drippers; cleaning the current internal drippers while they are installed (which is when they get clogged due to use) is not easy, there is a risk of losing water during cleaning and when they are very tight they require great manual effort, and if they are old or of poor quality, the plastic degrades and many times when trying to clean them they break.

Emitters made of flexible material can be used in standard or non-standard pipes, of any internal and/or external diameter with any pressure and in flat adductors (ceilings or floors). It allows them to be coupled to semi-rigid, rigid or flexible pipes, characteristics that do not have many current internal and external drippers, which is useful in pots, vertical gardens, greenhouses, arbors, shades, hydroponic cultivation...

On the external drippers that are "punctured" their advantages are:

- It does not "puncture", so there are no obstacles that reduce the head loss in the adduction pipes and allows the reuse of drip pipes already almost clogged and discarded.

- Facilitates installation, uninstallation and storage of pipes (there are no hooks or tripping), because it barely protrudes.

- The intake or puncture hole is not deformed and tightness is not lost with use (in non-permanent installations), which is the serious problem of putting external drippers that handling causes looseness and therefore water loss and lack of control of the dropper flow rate.

- Less material is needed to make drippers and pipes. Those who get punctured need thicker pipes to be able to get punctured, this system does not have that drawback because it adapts. Thinner thickness pipes are cheaper and reduce manufacturing and installation costs.

- It allows to mechanize the installation and collection in large irrigated areas, these operations due to the continuous hooks that occur, the proposed one made of transparent material allows to monitor the dripper to avoid clogging, observe the dirt and the precipitation of salts and carry out general cleaning or punctual at any time of use.

See Figure.-4 It allows having a socket for other implements which is a great advantage, by moving them we can close or regulate the flow of a dripper or turn it into a sprinkler, sprayer, micro-tube insertion point for remote dripping, etc. ; A single pipe with this system can irrigate and dose the water in different ways to different types of plants in very different ways, with unevenness and at the same time.

In some dripper design, a hole or small deposit, or more than one, or felt is placed in the path of the canaliculi at the beginning, in the middle of the path, or at the end in the exit hole, or felt where to put fertilizers or any other substance, hormone , or biological pesticide, etc. in the form of a slow-dissolving tablet (fried microelements type) that you want to apply continuously or sporadically to the plants when watering them, since these products or the felt itself dissolve in the passage of water; There are no drippers with these characteristics.

The felts are placed according to the specific needs of the plants, some even act with or as canaliculi which they can replace in part or completely, being a felt glued to a waterproof sheet (see Fig. 10).

In an irrigation installation with felt drippers, we water each plant from the same branch, covering different nutritional or physiological needs, pesticide treatments, etc. This versatility is very useful in garden plants, in research laboratories, seedbeds of all kinds, even in mushroom farms, fish farms, hydroponic cultivation or with substrates. The manufacturing of the drippers can be done with a roller on which 2 semicircular plates are placed on which the drippers are printed "like ounces of chocolate" with the separation between drippers with deeper grooves than the canaliculi of the drippers to to facilitate its cutting and separation, the shape can have any design, although the rectangular, square, triangular, or hexagonal ones are preferable to the rounded ones because with these last designs some material is lost when printing the plate.

Before extruding or printing the drippers on the continuous plate, one or more embedded meshes or nets of more resistant materials can be placed to strengthen the structure of the dripper, when the printing roller rotates on the continuous hot plate-belt; Plates can be manufactured with many droppers printed in low-relief, like a printing press, both systems greatly reduce manufacturing costs.

Another option is the drip pipe; As the plastic cools, when it is manufactured hot, the canaliculi are printed and plastic sheets with or without internal canaliculi or with smooth felts are placed in the factory or later in drippers.

This drip pipe has minimal projections that further prevents snags when handling it and many variations. Fig. 7 or use two sandwich-type drippers facing each other Fig. 9 and communicate them by means of a tube to a dripper with the adductor pipe, or put more hooking holes and gadgets.

A detailed exposition of an embodiment of the invention is not precise because with the explanation and drawings it is known how to do it. Dripper plates or sheets with channeling, as such, have many applications, unrelated to drip irrigation, that require and for which their own patent has been applied for.
