Description

OBJECT OF THE INVENTION

The present invention relates to a raft for hydroponic cultivation of lettuce and / or vegetables, whose obvious purpose is to achieve the mass cultivation of these vegetables without the need for planting or sowing them on land.

The object of the invention is to provide a raft that can be mounted in any greenhouse or even outdoors, establishing a surface of varying dimensions to allow the cultivation of lettuce and / or vegetables without the need of water tanks for water supply.

BACKGROUND OF THE INVENTION

The existence of rafts that allow a hydroponic cultivation of lettuce and / or vegetables is unknown, as is the subject of this utility model.

DESCRIPTION OF THE INVENTION

The raft that is recommended, being able to have any width and be of one contour or another, has the particularity that it is constituted from a kind of tubular frame of remarkable diameter and formed by the successive coupling of different sections of tubes to close the frame, this being preferably rectangular or quadrangular, without discarding other contours in which depending on said contour the tubes will have one or another path and can be attachable, by elbows in the case of quadrangular or rectangular frames, that is elbows at right angles, or elbows in an obtuse or acute angle, in the case of polygonal contours other than the one mentioned.

The tubes will preferably be of PVC and together will form a structure of high strength and capacity for the water used in the hydroponic cultivation of lettuce and / or vegetables, such that said tubular frame is fixed to a plastic surface that will constitute the bottom or base of the raft, so that the plastic surface will be of amplitude greater than that of the frame to carry out a partial wrapping of the excess plastic on the frame itself, and fixing that surplus and plastic wrap on the tubes, by means of rivets with the collaboration of perforated discs and that will be housed in alignments of holes established for this purpose in a part or upper alignment of the tubes that constitute the tubular frame, so that these discs can be obtained from the tubes themselves, or be discs foreign, but always with a curvature that adapts to that of the tubes themselves in which the rivets are applied to hold the plastic.

In this way a raft is obtained with a constitutive structure of the frame itself, and a plastic surface as the bottom or base of the raft, counting the tubes with other holes of greater diameter to those of fixing the plastic, which are oriented towards the inside, according to a 90º lag with respect to those provided above for fixing the plastic to the tubes, so that these second tubes allow the filling of the raft when water is introduced into the interior of the tubular frame, leaving the holes inside the raft until its filling, whose depth will logically be the diameter of the tubes that constitute the frame.

Holes are also included at the bottom to allow emptying if necessary.

The pool thus constituted is of great weight, not only the water contained in the tubular frame, but also for the content in the pool itself, keeping the plastic stretched and glued to the ground.

Above and on the surface of the water, a cover based on polyethylene sheets will be provided occupying the entire width of the interior of the raft, so that the aforementioned polyethylene sheets are affected by holes at appropriate distances so that in each one of them a lettuce is arranged for their cultivation, with which they will absorb the water inside the raft and a hydroponic cultivation will be achieved.

In the constitutive structure of the PVC frame or pipes it is possible to install water heaters, pH and conductivity controllers, as well as other means for providing nutrients, etc.

Said pool will also be complemented by an ozone system based on a submersible pump that is introduced through a large hole made for the purpose in the upper part of one of the frame tubes, said pump being connected by a polyurethane tube to a Venturi and a check valve and where the Venturi will present at its exit a long tube that is introduced into the tubular frame so that it runs through the interior, according to a path corresponding to the complete contour of the frame and even more, for the application of ozone to the liquid or water contained in the frame and then for application to the rest of the water contained in the raft.

The check valve connected to the submersible pump is in turn connected to an ozone generating machine, so that due to the volatility of the ozone itself, it is convenient for the ozonated water to circulate as little time as possible inside the structure. , that is to say, of the tubular frame, without mixing with the rest of the untreated water, which is why this long duct that runs through the inside of the frame is used, ending at the end inside the raft through a hole in the frame itself tubular.

Based on the submersible pump it is possible to carry out an ozonation of the water to eliminate with it bacteria, viruses, algae, green, etc., also keeping the water permanently clean without leaving the raft at any time, which will save external deposits, since the water consumed will be only that required by lettuce and / or vegetables for growth.

The raft with the characteristics mentioned and the ozone application system as part of it, does not require external deposits since the required water never leaves the raft, also allowing to separate the treated water with ozone from the untreated, by circulation of the water inside the tubular frame corresponding to the structure of the pool itself.

Also the application of ozonized water allows lettuce and / or vegetables to acquire more flavor, grow faster and ultimately achieve greater production, without forgetting a better presence with respect to traditional farming systems and better conservation, avoiding or canceling virtually all diseases acquired in conventional crops and therefore requiring less fungicidal, bactericidal and disinfectant action.

Finally, to say that regardless of the contour that the raft may have, it has already been said that the amplitude of the raft may be variable, thereby allowing to take advantage of the greenhouse surface, or even place it outside the greenhouse or in any place that is deemed necessary, according to the time of the year.

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, the raft of the invention is constituted by a tubular structure (1) based on tubes that determine a tubular frame, which in the referred figures is rectangular in shape, such that said tubular structure or frame

(1) is arranged on a plastic sheet whose amplitude will be slightly greater than the amplitude of the tubular structure (1), so that the remaining part of said plastic sheet, generally referenced with the number (2), is folded in an envelope on the lateral and upper surface of the tubes of the structure (1), as shown in Figures 1 and 2, and the fixing of said plastic sheet (2) to the tubular structure (1) is finished, fixing that is carried out by means of a series of rivets that are arranged superiorly through the wrapping part of the plastic sheet (2) and are fixed in holes made for this purpose according to a superior alignment in each of the sections of the tubular structure (1) , complementing the fixation with discs or washers (3) through which the rivets are through and that adapt to the upper and curved surface of the tubes that form the structure (1), thus being perfectly fixed the plastic sheet or (2) to the entire perimeter of the structure (1), as shown in detail in Figure 2, tubular structure based on tubes that may be 15 cm. in diameter, 20 cm, even 30 cm. or more, they are affected by a superior alignment of holes for the passage of the said rivets and positioned on them of the discs or washers (3), which will offer the same curvature as the tubes of the structure (1) to adapt and remain The plastic sheet (2) is perfectly fixed and sealed on the tubular structure (1).

At 90º of these fixing holes, the tubes of the tubular structure (1) are affected by other holes (4) of greater diameter for filling, these holes (4) being oriented inwards logically corresponding to the corresponding average height to the structure tubes (1). The discs extracted two of these holes (4) are those that may constitute the washers or discs (3) that participate in the fixing and sealing of the plastic sheet (2) on the tubular structure (1).

Logically, the plastic sheet (2) will extend over the floor and the tubular structure (1) will be arranged thereon, to then carry out the folding and wrapping of the excess plastic on the lateral and upper surface of the tubular structure ( 1) as shown in Figures 1 and 2, to carry out the abovementioned fixation, thus obtaining a raft that can be filled with water for the hydroponic cultivation of lettuce (5), as depicted in Figure 3, for which it is envisaged that on the surface of the water that fills the raft as a whole, a series of polyethylene sheets (6) with holes (7) are arranged, in each of which a lettuce (5) will be arranged for its cultivation and growth, so the roots of that lettuce (5) through the holes (7) will feed on the water of the raft and the nutrients that can be applied to it.

Said raft assembly is further complemented by an ozonation system constituted from a submersible pump (7) that is introduced through a wide hole (8) that is made for this purpose in one of the tubes of the tubular structure (1 ) ,, to which it is connected, through a tube (9) with a check valve (10) and with a Venturi tube (11), while the check valve (10) is connected through a conduit (12) to an ozone machine (13), as shown in Figure 4.

In addition, the Venturi tube (11) is connected to a long tube

(14) that is introduced inside the tubular structure (1) through the appropriate hole, circulating inside it in all its contour and even more, so that through the ozonation machine (13) it is achieved ozonize the water that will first correspond to that contained in the tubular structure (1) and then to that contained in the raft.

As is evident, the tubular structure (1) will be formed on the basis of the correlative coupling of tubes that, in the changes of trajectory, will be coupled to corresponding elbows at right angles in the case of rectangular rafts, and at obtuse or acute angles in the case of rafts of another contour, or even in the case of oval, circular rafts, etc., without elbows but with the tubes (1) with the opportune trajectory and with successive coupling between them, and always with a variable contour amplitude, as already It has been exposed throughout the present description, that is to say that the surface that the raft occupies may be any, of greater or lesser size depending on the place where it is to be located and the amount of cultivation to be carried out.
