Definitions
- the present invention relates to a system that has been specially designed to provide adequate fertilizers, to a given land surface, through the water with which said surface is irrigated.
- the object of the invention is that the contribution of irrigation water is always accompanied by an appropriate contribution of fertilizer, in order that the contribution of nutrients to the soil is carried out homogeneously throughout the entire irrigation season.
- the invention provides for the use of fertilizing substances that can be powdery, crystalline, micro-granulated, granulated or compacted in one or more pieces, marketed in a sealed container and that progressively dissolve upon contact with water, specifically when circulating the water through the inside of said container.
- the invention is in the field of irrigation facilities, especially in installations for gardening irrigation and the like.
- a sealed container of plastic material, containing fertilizer is used, a container that is intended to be introduced into a container holder, in turn equipped with a sealed closure, based on a body and a lid, intended to be inserted into a branch of the irrigation water supply conduit, by way of bypass, so that part of the water passes through the container holder, entering through its lid and leaving through its bottom, thanks to that in the closing maneuver of the same one the rupture of the lid and the bottom of the container takes place, so that as the water passes through the device the dissolution of the fertilizer takes place and the drag of the same by the water.
- the dosage of the fertilizer is not as accurate as desired.
- the pressure in the container holder is practically the network pressure, which is undesirable in certain cases, such as in the irrigation of large areas, with significant water flows and high pressure levels.
- the system lacks a procedure for air evacuation contained in the lower part when introducing the container containing the fertilizer and closing it, and that would accumulate, since its density is lower than that of water, in the upper part of the container holder, which can pose a danger to the air being a compressible fluid and work the device under pressure.
- the system lacks a control of the amount of fertilizers available at all times, so that the replacement of the container must be made by forecasts of its duration, which is inaccurate and sometimes the intended constant feeding of fertilizers is interrupted during periods of more or less long time.
- the system works at constant pressure in the injection, for which a pressure regulator that maintains the constant pressure at its exit, regardless of the inlet pressure, a check valve located at the outlet of the device, which prevents the pressure of the device from equalizing that of the network by equalizing pressures in the outlet orifice, and a safety valve that guarantees that The pressure will not be exceeded in the event of an alleged failure in any of the aforementioned components, a valve that will open allowing liquid contained inside the device to escape, in the event that the pressure at which said valve is tared is exceeded.
- the fertilizer solution injector element is based on the Venturi principle, and specially designed to work on pressure in the injection and to minimize system load losses. It is connected to the inlet pipe, the outlet pipe, the outlet of the extraction cavity, the depressurization outlet valve and the upper part of the lower part, which allows the evacuation of the accumulated air in this area After the change of packaging.
- both the inlet and the outlet of water are established at the bottom of the container and at the bottom of the container holder, causing the appropriate breaks at the bottom of the container during the maneuver of closing the container holder, which leaves the upper lid of said container holder free, for which a bayonet-type closure is provided, with means that facilitate the manual tightening of said lid in the closing maneuver.
- the package instead of being closed by heat welding with the PCT, is closed by irreversible tongue and groove coupling, which simplifies the closing process as the use of thermal machines is not necessary.
- the incorporation of a peephole that allows visualizing the mixture leaving the container is provided, so that as long as there is fertilizer in said container the mixture will be colored, but in the At which point the fertilizer runs out, the color in the sight glass will disappear.
- FIG. 1 is a representation of the container filled with crystalline fertilizer according to the invention.
- FIG. 2 is a representation of the empty container according to the invention.
- FIG. 3 is a representation of the base of the container (tub) indicating its weak parts to facilitate its perforation.
- FIG. 4 is an enlarged view of the container sealing system according to an embodiment of the invention.
- - Figure 5 is a global view of the system.
- - Figure 6 is a representation of the lower part or base of the device showing its upper cavity (extraction cavity) with the fertilizer solution injection element and the perforation plate inside.
- FIG. 7 is another basic representation of the device showing its extraction cavity with the injection element and the outlet orifice of the fertilizer solution.
- FIG. 8 is a representation of the base of the device showing its lower cavity with the pressure controller assembly and the injector element inside.
- FIG. 9 is a representation of the upper part or cover of the device showing a system of inclined and complementary tabs with those of the lower part and the prominences to which the special keys will be adjusted to ensure the closure of the device.
- FIG. 10 is a detail of the hermetic closing system of the device, in which it is also shown how the inner ribs of the upper part house and press the container to ensure its complete perforation allowing the location of the handle of the container.
- - Figure 11 is a representation of the perforation plate, where the hole where the water injection element will be fitted is indicated, determining its unique position within the extraction cavity.
- - Figure 12 is a representation of the special keys to ensure the hermetic closure of the device, where the parts that are conjugated with the lower and upper parts of the device are shown.
- FIG. 13 is a representation of how the special keys fit the lower and upper parts of the device and how the seal is achieved.
- FIG. 14 is a section of the device that shows how the system works as a whole.
- FIG. 15 shows the hole in the upper part of the lower part of the device that will allow the evacuation of the air after the change of container.
- FIG. 16 consists of a representation of the connection of the hole in the upper part of the lower part of the device with the injection point, from which the air contained in this area will be sucked.
- a container (1) is configured that configures a kind of tub, of appropriate capacity, with its corresponding lid (2 ), that it also incorporates a handle (3) to facilitate its handling, said container containing the soluble fertilizer (4) and being tightly closed by means of the tongue and groove coupling shown in Figure 4, which facilitates the assembly of the lid by simple pressure, but which prevents the decoupling of it, acting as a seal.
- a plurality of weakened areas (5) are established, which facilitate its perforation during the closing maneuver of the container holder, obtaining the injection perforations of water and extraction of the fertilizer solution, regardless of the position in which the container is inserted, as will be seen later.
- the container holder As for the container holder and as shown in particular in Figures 5, 6 and 7, it has a lower body or part (8), which can be sealed by the lid (9), said body (8) having an inlet pipe (10) ) and an outlet pipe (11), which together with the container holder itself determine a bypass for the main water circulation pipe (13), a pipe that in the interval corresponding to said bypass incorporates a regulating valve injection (12).
- a housing (15) for the container (1) is established, at the bottom of which a plate is placed of drilling (14) and a water injector element (16).
- a peephole (17) is established on the body wall (17) that allows estimating the moment in which the contents of the container (1), ie the fertilizer (4), have been finished.
- an outlet (18) of the fertilizer solution is established, located under the perforation plate (14) which rests on a plurality of ribs ( 19) especially visible in figure 7. Additionally, a hole is established in its upper part (38) which is connected to the injection (39) for the evacuation of air, as can be seen in figures 15 and 16.
- the base body (8) below its housing (14), is hollow, and defines a cavity (21) in which the pressure regulator assembly (22) is housed, signaled by an oval in Figure 8, set regulator consisting of a pressure controller (23), a check valve (24), a safety valve (25) and a small pipe that communicates with a depressurization valve (26), normally closed. Also inside this lower cavity (21) the injector element (27) of the fertilizer solution is located.
- relief elements (33) responsible for perforating the weakening (5) of the bottom of the container (1), also incorporating an orifice (34) which will determine its unique position within the extraction cavity of the base of the device, since the water injection element will be inserted into it.
