Definitions
- the electrostatic concept consists in the application of an aqueous solution, the drop of which is micronized and converted into a soft mist.
- This micro drop is driven with a very efficient carrier that is the air, which micronizes the drop and when leaving the mouthpiece a strong positive electric charge is printed, which produces a change of polarity in the solution since by repulsion of loads, the positive ones of the solution "start " by the machine, leaving the micro-drops negatively charged.
- the cloud of drops with negative charge creates a momentary imbalance of charges on the object that will receive the application, since its negative charges are repelled and they go to earth, leaving it positively charged.
- the negative microdrops are strongly attracted to the object, being embraced and completely covered by this mist.
- This application technology ensures that products are attracted to the plant as well as small pieces of metal are attracted to a magnet.
- the micro-drops adhere to the objective attracted by the difference in loads, thus reducing the losses caused by runoff and bypass caused by the wind, achieving an extraordinary coverage of it, and therefore, a superior effect of the products applied.
- This makes it possible to significantly reduce the amount of chemical products to be applied per hectare thanks to the great efficiency that is achieved, which ultimately means reducing the negative impact of the use of pesticides on the environment.
- the producer obtains healthier fruits, of a better size, firmer, of a better color, at a lower cost and with minimal environmental damage.
- each drop l lightly has an equal static charge, means that as long as the drops are on their way to the target they do not join together (equal charges repel each other), therefore they look for their space by depositing in an extremely uniform way. Only by adhering to the positively charged surface of the plant do they lose their charge and are fixed without producing runoff.
- the coating with the electrostatic application is a thin layer of micro drops well distributed on both sides of the sheet, unlike conventional applications that have a very variable drop size, a more uneven plant cover and the surface that does not Faces the application does not receive product.
- the low volume of water used by pre-existing electrostatic technology is due to an adaptation of this technology used in other areas, and not to the development of new specific technologies for agriculture.
- This technology can be used in any type of crop. From fruit orchards to extensive crops as important as wheat, corn, marigold, and others, which at present have not been efficiently addressed with new technologies.
- the present innovation consists of a system for the preferential application of phytosanitary products that uses the principle of electrostatic attraction: - With a technology that allows the micro-drops to be printed on the nozzle a high static charge and with high flow rates of mojam iento. - With an industrial design of great simplicity and with very low probability of failures, which makes it very stable and reliable. - With the option of using an active water nozzle for the nozzles, which produces a better efficiency in the use of air to micronize the drop. - With the option of using a dosage! ' of chemicals in the mouthpiece itself.
- the force of attraction with which the electrostatically charged drop will be attracted to the purpose of the application will depend directly on the ability of the machine to print the static charge. The higher the load, the more attraction the application will have, achieving a greater and better enveloping effect and allowing the product to cover 1 00% of the target surface.
- Sixfold the burden of prior art technologies means a great increase in efficiency thanks to electrostatic attraction. This accompanied by a greater flow, delivers an application of features never seen before in the field.
- the greater electrostatic charge in the drop allows the attractive force to be so strong that it will also ensure a very good coverage and deposit of the products, also achieving great efficiency in the use of the machinery.
- the system subject of this application has the ability to apply adjustable flow rates, which will reach a maximum flow rate per boiler which will increase that of pre-existing electrostatic machines, and not only without sacrificing the electrostatic charge level but also maintaining it six times higher than in their case.
- adjustable flow rates which will reach a maximum flow rate per boiler which will increase that of pre-existing electrostatic machines, and not only without sacrificing the electrostatic charge level but also maintaining it six times higher than in their case.
- Air use efficiency The machines of our innovation have the option of using baquillas with fixed or active water jets.
- the use of an active water dispenser translates into a more perfect micronization of the water drop, with less air consumption to achieve it. This implies that the source of air needed to supply it can be of a smaller capacity, which is also very important from the point of view of the power saving required for the tractor or the towing vehicle that makes it work. It should be mentioned that with this system we achieve at least a 20% saving of this resource with respect to everything that exists in the market that uses the electrostatic principle with nozzle charge. This is very important from the commercial point of view, since many producers will not need to make investments in other types of more powerful and expensive dragging machines than they already have, to enter the use of these high flow electrostatic machines.
- Dosage in the nozzle The system has the possibility of dosing the chemical products to be applied accurately in the nozzles. This means that it is not necessary to make mixtures of products in the main water tank, which has great advantages from the point of view of the decrease in product handling by operators.
- the dosing system is controlled by a microprocessor. The microprocessor also allows you to keep an accurate record of the events of the applications and the use of each product, delivering an application control tool of great value to the producers.
- Machines with existing low flow application technologies that use electrostatic charge are capable of applying no more than 70 to 90 liters per hectare at a speed of 5 km / H, maintaining a sufficient charge in the drop.
- the attraction of loads implies that this low wetting will remain on the first surface that attracts it, which does not allow that technology with such a low flow can be used for fruit orchards that are not conducted in a flat type system, such as palmettes, browns and vines, where the foliage is thin. Therefore they are not used in orchards of fruit trees without structure, where with our development we can do it, with flows of up to 14 times higher per hectare, measured in the same conditions and at the same speed as in the aforementioned case.

- the bar (or "Bank of Nozzles") of the electrostatics fulfills the function of housing the nozzles, which are the ones that make the sprinkling of water or solution with products, which is the objective of the development of this innovation.
- the supply of air, water and high voltage to each nozzle must be produced, and in some cases of chemical products independently.
- the air breaks or micronizes the water drop, in addition to serving as a transport of the micronized drop to the purpose of the application.
- the water is in solution with the chemicals to be sprayed, but if the dosing option with injection in the nozzle is used, the provision of water and chemical products occurs separately.
- the bar is constructed from a sealed tube (Fig. La), hermetically sealed at the ends, which allows it to fulfill multiple functions, such as: Protecting its contents, making the electrical connection to the mouthpieces llas and be the air collector for them, this being the only bar with electrostatic technology that does not need a special air manifold since the bar itself fulfills this function.
- air collector a receptacle that serves to store the passing air and distribute it to the nozzles.
- the hermetic seal of the tube is achieved by means of two preferably rigid plastic caps fastened by screws (Fig. La, # 1 and Fig. 2), but which can also be secured by another fixing system such as a bayonet system, simply thread or some type of adhesive.
- Each cover has a seal in its joint with the tube, which fulfills the function of covering in this case the head of the clamping screws and isolating the high tension, in addition to sealing the joint (Fig. La, # 78 ; Fig. 2a, # 10 and Fig. 2b, # 1 1).
- the objective is to create this large air collector, isolate and seal its contents from the outside, and maintain inside it the pressure of compressed air with which the system works.
- This tube is preferably cylindrical but can also be otherwise. The most commonly used is 75 mm in diameter, however this measure may vary.
- the tube used is preferably made of stainless steel and with an insulating cover for electricity, preferably of composite materials such as glass fiber or carbon pound (Fig. 1, # 2).
- This metal structure of the bar is what makes the positive electrical connection of the high voltage to the nozzles.
- this tube can also be of another metal or even another rigid electrical insulating material, such as some PVC or other plastic, using an electrical connection not by the tube itself but by another additional electrical conductor, such as a tape, piggy bank, cable, wire, conductive paint such as silver paint, or others.
- the fact that the bar itself is the air collector is important since it implies that it is not required in the process of manufacturing a precision fit between the input terminals and their internal structures, that is, since the entire tube is a air collector, both the nozzles and the air inlet to the bar can be anywhere in it.
- Each bar has in its lower part a small perforation, which constitutes in itself the system of evacuation of internal spills of water or solution with chemical products to the outside. System that works efficiently when driven by the internal air pressure of the bar (Fig. La, # 3).
- the internal connections from the terminals of the bar to the water collectors (Fig. I d, # 25), and of chemical products (Fig. I d, # 26), are made by means of hoses.
- the positive high voltage connection is made directly to the rod tube from which it connects to the nozzles (Page 8, lines 26 and 27), (Fig. 1, # 4; Fig. I d, # 27 and Fig. Le , # 28).
- the connection from the bar terminal to the Nozzles must be made using an additional driver (Page 8, lines 27 to 30).
- the ground connection is made through the bolt of the clamp leg to the support structure for the bar (Fig. Le, # 29), (Page 1 0, lines 36 to 40).
- the bars can be directly interconnected by means of the covers (Fig. 2a, # 9 and Fig. 2b, # 12).
- the lid is double, that is, it is a single piece that closes, seals, holds together and connects both bars inside.
- This connection inside is by means of a simple perforation (Fig. 2b, # 1 3), which also allows to make the electrical connections (Fig. 2b, # 14), to interconnect the water collectors (Fig. 2b, # 1 5) and chemicals when applicable.
- Each bar has in its interior a piece that we call “water collector” (Fig. L e, # 16), which has more functions than collecting and distributing it.
- water collector a receptacle that serves to store this passage liquid, and distribute it to the nozzles. Apart from performing this work, this piece fulfills the important function of being the return connection of the positive charges from inside the nozzles (Fig. Le, # 1 7), this innovation is a key factor to achieve its performance of load.
- the individual water jets are housed to each of the nozzles of said bar (Fig. Le, # 1 8), which makes the collector itself also becomes an integral part of each nozzle, which does not It is found in the prior art machines of electrostatic technology.
- water dispenser a small tube that carries water from the collector, to each of the nozzles, also making the connection for the return of positive charges from them.
- the collector is a preferably cylindrical tube, preferably of 1 0 mm diameter stainless steel, however it can be in another form, another measure and also of another electrical conductive material such as aluminum, copper, bronze or others. It can even be made of an electrical non-conductive material, and make the connection by means of an additional electrical conductor such as a tape, wire, cable, wire, conductive paint such as silver paint, or others.
- the water dispenser is also a preferably cylindrical tube, preferably of 2 mm diameter stainless steel, however it can be in another form, another measure and also of another electrical conductive material such as aluminum, copper, bronze or others.
- each bar has inside a chemical collector next to the water collector and mounted in parallel, to carry chemical products at all nozzles (Fig. I d, # 19).
- chemical collector a receptacle that serves to store these products of passage and distribute them to the nozzles.
- This collector is mounted in the container of each nozzle (Fig. I d, # 20), in the same way as the water collector does. It is a preferably cylindrical tube, preferably of 6.3 mm diameter stainless steel, however it can be of another shape, of another material and also of another measure. In this collector are housed the dispensing needles of individual chemicals for each of the nozzles (Fig.
- the needles are preferably in the form of a cylindrical tube, preferably stainless steel and 0.8 mm in diameter. However, they may be of another measure, of another material and also of another form, as long as they fulfill their objective of delivering the chemical products in the manner described to The mouths.
- Each product collector has a chemical inlet (Fig. 1, # 7), which comes from a pi e chamber where they are mixed, located outside the bar.
- the water collector with the individual jets to each nozzle is electrically isolated from the external tube of the bar by means of the container of each nozzle. What makes the nozzle itself, is also the insulator of the high voltage of the electrical system. (Fig. I d, # 20). In the event that the container is made of an electrically conductive material, an additional insulator will be needed between the body of the nozzle and the water collector of the bar (Page 12, 7 to 9).
- the nozzles themselves are the mechanical fastening system of the water collector to the bar.
- the bodies of the nozzles (Fig. 1 c, # 33 and Fig. I d, # 34), are fixed to the bar by means of a lock on each of them (Fig. Le, # 3 1 and Fig.
- the nozzle bodies are attached to the container (Fig. Le, # 34 and Fig. I d, # 20), which holds the water collector (Page 1 2, lines 16 to 17), (Fig. le, # 35 and Fig. lf, # 36).
- the nozzles are the mechanical fastening system of the chemical collector (Page 1 2, lines 1 7 to 19), (Fig. I d, # 37).
- This design is extremely simple, allowing to significantly reduce the number of pieces used by prior art designs to achieve this goal. This simplicity of the design allows a great facility for its manufacture, cost savings and lower probability of failure.
- the electrical connections are made to the water collector in its negative connection (Page 9, lines 1 to 3), and to the sealed tube of the bar in its positive connection (Page 8, lines 26, 27 and 46 to 47) .
- the water collector acts as the electrical ground connection for the nozzles, since it is connected to the difference in negative voltage electrical potential which in turn is connected to the general ground of the transport vehicle (Tractor), and / or the machine same. In addition, the machine is directly connected to physical ground by metal drag chains.
- the tube of the bar in this case of stainless steel, acts as the connection with electrical potential difference of positive voltage of high voltage to the body of the nozzles.
- the electrical connections between interconnected or connected bars "in series" (Page 9, lines 5 to 9), are made by means of cables with terminals between both collectors and between the tubes of the bars (Fig. 2b, # 14).
- the fastening system of the bars to the support structure of the electrostatic machine is by means of fastening parts that we call "Legs" (Fig. 1, # 40; Fig. La, # 42 and Fig. Lf, # 41 ).
- These legs in addition to being said fastening system, electrically isolate the bar tube that has the positive connection, from the support structure of the machine, and electrically connect to ground through said structure. They are manufactured by two pieces of insulating material resistant to temperature and corrosion. A piece is located on the outside of the bar (Fig. 3b), and has a dry cavity or labyrinth that acts as an electrical insulator in the event of water or liquid runoff from the nozzles (Fig.
- the same tube of the bar acts as a structure, air collector and when it is manufactured with a metal like in this case stainless steel, it is the electrical conductor of the high tension for the nozzles.
- the nozzles in addition to their function as such, act as the electrical insulator of the water collector and mechanically they are the fastening system of the latter and when applicable, also of the chemical collector, to the bar itself.
- the water collector itself is the water collector, the clamping system of the water jets and the return of positive charges of each of the nozzles when discharged to ground.
- the nozzle is a key part of the spraying system of the machine, where the micronization of the drops to be sprayed and the electrostatic charge of these microdroplets occurs.
- This micronization is of great importance since the resulting size of the micro drops directly affects the quality of the load, in addition to that by themselves they have a better coverage than a larger drop. Thanks to this and the efficient electronic system a very high charge is achieved, up to six times greater than electrostatic machines of the prior art that use ten to fourteen times less water flow.
- the nozzle can be adapted to different air consumptions to micronize the drop, allowing machines of greater capacity to be manufactured at a lower power requirement for operation.
- Something that no machine of any kind in prior art machines has known.
- the design of the nozzles makes them very resistant to the effect of the electric arcs that are produced due to impurities in the product flow, which prevents them from burning, and therefore, significantly increases their useful life and makes them very reliable.
- nozzles have the capacity to deliver a flow rate up to five times higher and simultaneously sixfold the electrostatic charge of the microdroplets when compared with those of the electrostatic low flow pi and existing machines.
- Fig. 4 Each nozzle is composed of a body (Fig. 4, # 44 and Fig. 4a), a container (Fig. 4, # 45 and Fig. 4c), and a dispenser of water (Fig. 4, # 46 and Fig. 4b).
- the container is made of electrical insulating material, and keeps inside the body of the nozzle (Fig. 4). This is preferably plastic, high thermal and corrosion resistance, but it can be of another material.
- This electrical insulating material is used to contain the nozzle body and keep it electrically isolated from the negative connection of the high voltage.
- this container can also be of another non-insulating material, and use another material that electrically insulates them in the attachment of the nozzles to the water collector that carries the negative connection.
- Even the nozzle container and the body could be a single piece, of some conductive metal or even some non-conductive material and make the high voltage electrical connection by another additional conductor, as long as it complies with being isolated from the negative connection.
- this container may vary, while maintaining its function of: Maintaining the body of the nozzle and having it centered with respect to the axis of the water dispenser of each of them, and, electrically isolating the body of the nozzle from the connection negative of the high tension, which can also be done by an additional insulator in the case that this container is of conductive material.
- the container has two clamps integrated in its shape that hold the water collector (Fig. 4c, # 47). each of which is tightened by means of a screw (Fig. 4c, # 48 and Fig. 4d).
- the nozzle container with chemical injection has clamps composed of two pieces more than the previous one ( Figure 4e), to hold the chemical collector in addition to the water collector.
- the body of the nozzle (Fig. 4a), comprises: A fluid inlet (Fig. 4, # 49), a fluid outlet (Fig. 4, # 50), and an internal channel between said inlet and outflow of fluid (Fig. 4, # 5 1).
- a fluid inlet (Fig. 4, # 49)
- a fluid outlet (Fig. 4, # 50)
- an internal channel between said inlet and outflow of fluid (Fig. 4, # 5 1).
- Fig. 4, # 46 In the center of it, inside is located its water dispenser (Fig. 4, # 46).
- the centered position of the dispenser with respect to the mouthpiece body is given by the container.
- the body is constructed by a tube of preferably cylindrical shape. Their inner section is also preferably of circular section, however they can also be of another non-cylindrical geometric shape.
- the body tube is made of a material that is preferably conductive of electricity, preferably stainless steel. But it can also be of a non-conductive material of electricity or electrical semiconductor, in combination with a conductive material. As for example, ceramic plated with silver paint. A diameter of 6.3 mm is used, and a length of 12 mm, however the measurements may also vary.
- the water nozzle of the nozzle (Fig. 4, # 46), is described as an integral part of the water collector of the bar, since it is housed therein. However, although it has no direct contact with the body or the nozzle container, it is an integral part of it.
- This dispenser in addition to delivering the water to the nozzle, fulfills the important function of being the return of positive charges (Page 9, lines 1 8 to 20 and 25 to 3 1).
- the electrical connection between the nozzle body and the electrified bar tube is further strengthened by two preferably stainless steel filaments integrated between the nozzle body and the container (Fig. Le, # 73; Fig. 4d, # 53 and Fig. 4e, # 54), these may also be of another electrical conductive material.
- the connection can also be secured by conductive paint.
- the water spout is centered without contact, producing a window or space for the escape of the pressurized air flow (Fig. 4, # 49), with which is carried out the micronization of the drop inside the body of the nozzle.
- the water jets can be static (Fig. 4f, # 57): rigidly attached to the water collector of the bar, or active (Fig. 4h, # 58): flexibly attached to the water collector, of rotary or tilting configuration, of 2, 3, 4, 5 or N number of movements, which can be in triangle, star or any other way.
- the nozzle end of the nozzle that connects to the bar's water spout has a magnetic material toroidal ring attached (Fig. 4h, # 59), or the spout itself can be magnetic.
- the dispenser can be attracted by 2, 3, 4, 5 or " N number of electromagnetic coils, arranged outside the water conduit (Fig. 4j shows the coils (# 79), mounted on the armature (# 80)), generating the described movements:
- the electromagnetic coils When the electromagnetic coils are energized, they attract the toroidal ring or the magnetized spout body, changing the inclination of the water spout shaft (Fig. 4k), which rotates or swings on a material seal elastic (Fig.
- the internal channel of the nozzle body acts as an electrode, electrically charged with positive charge at a predetermined magnitude of voltage, which by repulsion of charges imparts an electrostatic charge of opposite charge, to the moving fluid that passes through said inner channel.
- a tangential charge is produced in the micro drop, diverting the positive charges to the pond and charging them negatively.
- a cover piece called "Nozzle Cap” (Fig. 5), whose objective is to protect it.
- the piece described can be independent or be part of the portion of composite fiberglass or carbon that insulates the bar (Page 8, lines 24 to 26).
- This top of the nozzle in its upper part has a perforation in the middle in the form of a conical trunk or flat bevel (Fig. 5, # 62), whose center shows the leakage vortex of the nozzle (Fig. Lf, # 63) , where the spray liquid is the object of this development.
- this cover forms an acute angle until it joins the bar (Fig. L f, # 64). This acute angle is important, since it mechanically protects the nozzle from objects that could hit it, such as branches. Making these objects instead of hitting the nozzle, slide and deflect without causing damage.
- the nozzles are airship (Fig. 1, # 65). These nozzles are installed in the bar covers (Fig. 6). The difference with the fixed nozzle, is that the nozzle container is cylindrical body (Fig. 6a), footwear inside another with cylindrical cavity (Fig. 6b, # 66), to allow the desired rotation (Fig. 6c).
- the airshipable nozzle is composed of a concavely shaped piece of insulating material (Fig. 6b, # 66), which inside has the cylindrical container (s) of these nozzles (Fig. 6a). This fit between the concave part of the piece and the convex part of the nozzle allows its rotation (Fig. 6c and Fig. 6, # 67).
- the water collector of these airships is short and acts as the axis on which these nozzles move (Fig. 6d).
- the collector as axis (Fig. 6d, # 68), rotates in a fixed piece that collects water for the airships nozzles (Fig. 6d, # 69).
- the rotation movement is selected by two "O" (O ' Rings) seals, (Fig. 6d, # 78).
- the collector of these is housed in the water collector (Fig. 6e, # 70).
- the water and chemical collectors of the irigible nozzles are connected to the main water and chemical collectors of the bar by means of hoses, (Fig. Le, # 74; Fig.
- the high-voltage connection of the airships is made by an electric conductor from the main bar to a terminal that connects the integrated fixtures between the body of the nozzle and the container (Fig. 6f, # 76), ( Page 12, lines 42 to 45).
- the complete system of the airship nozzle is fixed in position in the cylindrical cavity of the cover (Page 1 3 Lines 46 to 48), by means of a piece that presses the cylindrical body of the nozzles against the concave body of the system representing said cavity (Fig. 6g, 6h and Fig. 6, # 77).
- the main objective of the system electronics is to charge the microdrops negatively.
- the electronics deliver a high level of electrical voltage to the nozzle, and as the water flow passes through them, it loads the microdrops tangentially.
- the system electronics design consists of a circuit designed around two microprocessors.
- the microprocessors are able to continuously monitor the flow of water that is going through each set of nozzles and adapt the voltage delivered instantly, thus correcting and compensating for the variations that occur, whether they are produced by instruction of the operator or due to variations of the different system components. These adjustments are made continuously with the equipment operating in the normal operating range. If for any reason the equipment goes out of this range, the electronic system notifies the operator of the situation.
- This electronic design means that using the same or slightly higher voltage (between 1 0 and 25% more), to which existing electrostatic low-flow machines are used in the market, is able to apply ten to fourteen times more water, and charging still six times more than these machines.
- the electronics are capable of loading the drop that was previously unknown in the market. Thanks to an integral design not only of this electronics and microprocessor programs, but also for the integral design of the bar and nozzles.
