     PERFECTED SPRAYER The present invention, as the name implies, refers to a sprayer of the type comprising an air flow generator, preferably a turbine type, installed in a nozzle such that the air flow generated by the turbine is directs from inside that nozzle, usually towards a deflector that leads it to a window through which the flow of air exits to the outside, incorporating into it the phytosanitary product dosed by a series of nozzles that are in the area of influence of the air stream in such a way that such a product is transported by the outgoing air stream to the crop, characterized in that it determines the ideal outlet air stream for each spray according to parameters such as crop characteristics, factors 10 climatic or type of treatment among others and configures in a coordinated way the turbine and the window to obtain the proper output air flow and optimal performance of the spraying equipment with significant energy savings. The sector of the technique to which the invention belongs is agricultural machinery. BACKGROUND OF THE INVENTION Sprayers of the type of which comprise a turbine installed in a nozzle having a window through which the air flow is carried outside dragging the product to be sprayed dosed by nozzles are long known that are in the zone of influence of the air flow. 20 Normally the nozzles are located in the passage of the air flow itself in such a way that the dosing product is carried directly by the air flow, however there are devices in which the nozzles are separated from the air flow if well they project the product so that it is incorporated into said air flow. By saying that the nozzles are in the zone of influence of the air stream, both the nozzles that are in the passage of the air stream are encompassed, the product being incorporated into the stream from the moment it flows through the nozzle, as, being the nozzles away from the air stream, they are capable of projecting the product to be incorporated into the air stream. In this way it is achieved that the air flow carries the product, usually 30 phytosanitary, to the crop to which it should be applied. In general, in these sprayers, at best, the air flow was regulated for a type of crop, the air flow and product dispersion being constant throughout the spraying time or, if there were variations, they were due to the fact that the air generator geared with the motor of the towing vehicle, the speed of rotation being altered by increasing or decreasing the revolutions of such engine by altering the outgoing air flow without control. The waste of product was evident because on the one hand the spraying was still maintained in the intermediate areas where there is no vegetation and, on the other, the lack of control of the outgoing air flow caused or excessive force generating unwanted drifts or insufficient force resulting in the poor application of the product, which leads to the loss of part of the crop or the need for a new treatment. 5 To overcome the exposed problem, spray control systems have been developed and thus there are those that detect the presence or absence of plant mass by stopping the spray in the absence of it. British patent GB2214047 refers to a sprayer comprising a presence detector in such a way that in the absence of plant mass no atomization occurs and also comprises means for adjusting the amount of product dosed as a function of the speed of the towing vehicle, for achieve a uniform atomization, this patent does not relate means of control of the air flow independent of the engine of the towing vehicle. The Spanish patent ES2047997 has the purpose of an apparatus of the type indicated that allows to ensure a constant power air jet independently of the fan drive means. For this, it comprises a meter of the air flow and means to alter it in its origin and thus indicates as options the inclusion of fins or vents in the fan's suction area, means of variation of the section of the suction passage or means of variation of the pitch of the propeller, however this patent does not report 20 combined means. There is also patent literature related to sprayers with a higher degree of automation and lifting systems for the spray tubes, as in the case of US5098018, where a fan blade adjustment system and conical cavities are provided to keep constant along the entire spray arm the atomized air flow. There are numerous patents that refer to systems for adjusting the position of the blades of a propeller, most of them in the field of aviation and engines, serving as an example both the oldest DE19600660, DE4331825 or the most recent ES2356490, JP2006057627 or JPS5888498. 30 The applicant himself is the holder of a previous registration, the Spanish utility model U200301196 referred to a sprayer of the type comprising a turbine arranged inside a nozzle that directs the generated air flow towards dispensing nozzles arranged in the air outlet channel, whose characteristics is that the nozzle has a rectilinear movement of approach or distance of the nozzles 35 thereby achieving to narrow or widen the air outlet channel by altering the flow of outgoing air. This record does not present a combination of other elements that vary in the speed of air output. From the tests carried out, it has been observed that for each air flow that is desired to go outside transporting the product, there is a configuration of the turbine and the window in a coordinated manner that is optimal. We will understand by turbine configuration the suitability of the same for obtaining a specific air flow and as a window configuration the opening of the same to regulate the amount of air that goes outside per unit of time. The behavior of the air flow that goes outside is neither progressive nor proportional nor follows a simple arithmetic pattern, and thus a greater window opening, at the same air flow generated by the turbine, will not always imply a proportional increase in the output flow nor, on the other hand, the variation of the air flow generated by the turbine, at the same opening of 10 windows, will imply a proportional increase or decrease in the flow that goes outside. There are many factors that condition the output air flow, and only through the coordinated control of the flow generated by the turbine and the window opening, the adequate flow is achieved and in the most efficient way. None of the known sprayers, some of them incorporate any of the 15 cited patents, reach the level of energy and product optimization as the one that is the subject of the proposed patent. DESCRIPTION OF THE INVENTION The proposed invention relates to a device suitable for efficiently and accurately supplying the air flow required for each spraying operation. 20 The device comprises: 1.  At least one configurable turbine to regulate the outgoing air flow. 2.  A nozzle with at least one configurable window that acts in coordination with the turbine. 3.  Means to vary the turbine configuration. 25 4.  Means for varying the configuration of the nozzle window. 5.  Means to know the configuration of the turbine and the window. 6.  Means for calculating the optimum turbine and window configuration for each spraying operation. 7.  Means for adapting the sprayer according to the determined configuration 30 coordinating the turbine and window configuration. one. - The configurable turbine to regulate the outgoing air flow: The configurable expression means that it can alter some of its characteristics to vary the air flow. The characteristics that are foreseen as variable elements are the speed of rotation of the turbine and the angle of attack of the blades, being able to vary one of them or both. a) Turbine with variation of the rotation speed: In the case that a turbine is chosen in which the regulation of the outgoing air flow is carried out by means of the control of the rotation speed, the turbine must comprise elements that allow alter the speed of rotation. By way of example, a gearbox that can be associated with the turbine or, in the case of a turbine with an electric motor, a current variator or resistor, such as a potentiometer, can be mentioned. To be able to reverse the air flow in such a way that the air generated by the turbine goes outside through the protective grid, thus cleaning it of leaves and vegetation remains, it is necessary that the rotation of the turbine can be reversed and thus the gearbox must comprise an inverter gear of the turbine rotation and the current variator 10 must comprise a current inverter that will cause the motor rotation to be reversed, based on the premise that it is an electric motor that allows it. b) Turbine with adjustable blades. The adjustable blades are designed to vary the air flow without changing the speed of rotation of the turbine thus avoiding incorporating mechanical means of greater cost to vary the speed of rotation. However, there is no technical limitation to the concurrence of an element in the same turbine to vary the speed of rotation as before and some adjustable blades. The blades have rotational movement rotating on a longitudinal axis such that the transverse axis of each blade can vary its position from a positive angle to a negative one, taking as neutral or 0 ° the position in which the transverse axis of the blade It is perpendicular to the axis of the turbine. The angle of rotation will be from + 89º to ‐89º, preferably from + 50º to ‐50º, and preferably from +45 to ‐45º. The possibility that the blades can vary their position from a positive angle to a negative angle 25 and vice versa, allows the reversal of the air flow without the need to reverse the rotation of the turbine. In case of reversal of the air flow, the nozzle becomes a suction channel which, in this case, would be a secondary suction channel. The reversal of the air stream is especially useful for, for example, removing leaves and other plant debris from the grid of the primary suction channel. There are different systems to modify the angle of attack of the blades of a turbine being common that the blades have two axes, one on which rotation occurs and which we will call axis of rotation and another eccentric and that, in its movement, causes the rotation. The movement of the eccentric axis is produced thanks to the means to vary the position of the 35 blades. 2. - The configurable window that acts in conjunction with the turbine configuration. At present, sprayers that disperse product through nozzles mounted on a panel or vertical parallel panels are common, such nozzles being peripherally arranged to a turbine that generates a stream of air that, channeled, drags the product from the nozzles and drives it about the trees and plants to be treated. 5 These turbines to which reference has been made, are located in a nozzle, formed by a normally cylindrical hollow body. The nozzle is the element through which the air flow generated by the turbine runs during the spraying operations, while, according to the present invention, when the angle of attack of the blades is reversed the nozzle becomes a suction channel 10 of the turbine. To differentiate the usual suction channel and the suction channel when the angle of the blades is reversed, we will call the main suction channel the usual suction channel during spraying operations and the secondary suction channel to the suction channel during cleaning operations of the grid, where the blades are at a negative angle and the air stream is inverted. For spraying, it is necessary that the flow of air generated by the turbine and flowing through the nozzle, exits outside by dragging the product incorporated by the nozzles existing in the area of influence of the air flow. The exit to the outside takes place through one or more windows where at least one of them 20 is adjustable. We will call the open space window through which the air goes outside, normally it will coincide with the separation between the nozzle and the nozzle carrier panel unless the nozzles are mounted on another structure. With the regulation of that window, the flow of outgoing air and its characteristics of speed and drag pressure of the phytosanitary fluid are modified, thus controlling the penetration of the spray or cone of atomized fluid on the tree or plant, according to the needs of work required by the user, which determines a better use of the phytosanitary product that reaches the inner part of all the trees, achieving a saving in the consumption of said product, because less fluid is spilled or wasted by 30 around the trees. To vary the opening of the window it is necessary, either to move the nozzle, to move the nozzle holder panel or both, either of the above options being valid for the purpose of varying the opening of the window, however for constructive reasons it is decided , As will be explained later, by displacing the nozzle. 35 3. - Means to vary the turbine configuration:In a turbine whose speed of rotation is variable, the means for varying the configuration of the turbine will comprise a gearbox or, in the case of a turbine driven by an electric motor, a power variator such as a potentiometer. In a turbine with adjustable blades, which can be of variable or constant rotational speed, the turbine comprises a precision actuator that we will call the turbine actuator. This precision actuator, preferably electric, acts on the eccentric shafts of the blades causing its movement. For this, the end of the eccentric axes of each blade is housed in a channel that runs along the side of a drum and which we will call a circular perimeter channel. This drum is located on the axis of rotation of the turbine inside the bearing on which the blades rotate and preferably participates in the movement of the axis of rotation of the turbine. The reciprocating displacement of the drum, pushed or stretched by the turbine actuator, causes the movement of the ends of the eccentric axes of each of the blades causing their rotation on its axis of rotation. The aforementioned actuator exerts force on the drum by pushing or stretching it through a precise, preferably direct transmission. Four. - Means for varying the configuration of the window To vary the configuration of the window it will be necessary to either move the nozzle, either move the nozzle holder panel or both, either of the above options being valid for the purpose of varying the window configuration , However, for constructive reasons, it is decided to displace the nozzle. For this, the nozzle is capable of moving with a reciprocating reciprocating movement in approximation or separation to the spray nozzles, by means of actuation of pusher means preferably arranged in an area of the nozzle front. To facilitate rectilinear displacement, the incorporation of guides 25 preferably arranged on the periphery of the nozzle is provided. Likewise, the invention is characterized in that the nozzle pusher means comprise at least one millimetric displacement piston which we will call the nozzle actuator, commanded by an integrated circuit with control knob. Said nozzle actuator is connected to the nozzle through a transmission which we will call nozzle transmission. The nozzle actuator, in its controlled advance, allows the nozzle to be guided, in approximation to the spray nozzles, while with the withdrawal of the nozzle actuator the separation of the nozzle from said nozzles is caused. The dimensions of said opening will condition the flow of air that goes outside. 355. - Means to know the configuration of the turbine and the window: Information of the gearbox, of the current variator, calculation of the position from a known position or position sensors of the blades and position sensors of the window. In a turbine that includes a gearbox the gearbox itself provides information on the configuration of the turbine. 5 In a turbine driven by an electric motor where the speed is variable through a current variator such as a potentiometer, it will be said variator who will give us the data of the turbine configuration. In a turbine where the blades are adjustable it is necessary to know the position in which the blades are to be able to determine the necessary movement to adapt to the configuration determined for the particular spraying operations. For this, the position of the blades can be calculated starting from the last known position and taking into consideration the movement exerted by the turbine actuator obtaining the current position of the blades. Another alternative is the use of sensors. 15 The introduction of sensors in the turbine for its location in the blades could cause problems, firstly due to the difficulties of connecting sensors arranged in a rotating element and secondly due to the risk of loss of calibration when constantly subjected to centrifugal forces. To avoid the exposed problems, the sensors have been arranged in an external zone and 20 away from the blades. To differentiate them from others, we will refer to them as blade sensors. The blade sensors are located in the turbine actuator or in the turbine transmission, although preferably in the turbine actuator to take advantage of the channels for the connections that must necessarily reach this actuator. 25 Thus, since the turbine transmission is accurate, the data obtained in the actuator regarding its position, allow us to know the position of the blades. As in the case of the means to know the turbine configuration, it is necessary to know the configuration of the window to carry out the variations that adjust it to the desired situation. 30 Also, as in the case of the blades, the configuration of the window based on the last known configuration could be calculated and taking into account the movement exerted by the window actuator, the use of sensors also being possible alternately what we will call window sensors. The use of sensors in the window itself may not be advisable due to the risk of loss of calibration as it is constantly subjected to strong air currents as well as the presence of constant humidity. To solve the exposed problems, the window sensors are located in an area away from the window and the air currents, preferably in the piston of the actuator 5 of the nozzle. A transmission system without gaps, direct and precise, allows, with little margin of error, to know the position of the window knowing the data of the actuator piston. 6. - Means for calculating the optimum turbine and window configuration for each spraying operation. 10 As stated, the combined use of turbine configuration and window configuration allows to obtain an optimum sprayer configuration for each required air flow. The first question is the determination of the optimum air flow for each spray, which will be carried out in an automated way taking into account 15 parameters such as type of crop, type of treatment, type of pruning, volume of vegetation per unit area , Treatment dose, atmospheric conditions, vehicle speed or nozzle relief among others. These parameters can be entered manually on each occasion but they can also come totally or partially memorized from previous processes or databases. 20 There are also parameters that can be obtained from external sources such as meteorological data or through sensors installed from the spray equipment itself, including in this concept also its accessories and complements such as trailer or tractor unit among others. A processor calculates the required air flow based on the parameters to be taken into account for that particular spray. After obtaining the necessary air flow data, the sprayer can calculate the optimum configuration or search the stored library for the optimum turbine and window configurations for each air flow. Therefore, the means for determining the optimum configuration of the sprayer 30 comprise: 1.  Means for entering data into the system. The introduction can be: a.  Manual data entry. b.  Recovery of data previously entered into a memory. C.  Obtaining data from external sources. 35 d.  Obtaining data from sensors located in the sprayer itself. 2.  Memory for data storage. 3.  Processor for: a.  The determination of the air flow either by calculation or by consulting pre-recorded libraries of air flows for each spray. b.  The determination of the optimum turbine and window configuration, either by calculation or by consultation with the library of optimal configurations for each required flow. 7. - Means to coordinate the turbine configuration and the window configuration to obtain the optimum sprayer configuration. Once the turbine configuration and the window configuration have been defined, the sprayer comprises means for executing this configuration, bringing the turbine and the window to the appropriate configuration. The means for coordinating the movements and positions of blades and The window includes:  Connections with the turbine gearbox or with the electric power inverter or with the blade sensors to know the turbine configuration at that time and which we will call the turbine start configuration. This starting configuration can also be obtained by calculation from a last known position.  Connections with the sensors of the window to know the configuration of the window at that time, which we will call the window's initial configuration. 20 This starting configuration can also be obtained by calculation from a last known position.  A processor for the calculation of, where appropriate, the starting positions as set forth in previous paragraphs, as well as the necessary actions to move from the start configurations to the optimum configuration in each case. 25  Connections to the gearbox, power drives or actuators to activate them, bringing the sprayer to its optimum configuration. The concept of connections implies both cable connections and wireless connections, serving as an example those currently known as wi-fi, bluetooth or radio, as well as those that may be developed in the future. 30 As an example of the results obtained through the coordinated action of blade angulation and window opening, the following table is attached: ANGLE (º) CHANNEL OPENING A (mm) Average Vel (m / s) QTOTAL (m3 / h) POWER (CV) 20 ° 110 24,94755700,09823,460 20 ° 130 23,30456058,46623,588 20 ° 150 21,78756390,83422,754 25 ° 110 30,44968367,33428,150 25 ° 130 28,53968960, 52528,06025 ° 150 27,30471259,40029,623 30 ° 110 35,31979016,41137,703 30 ° 130 33,75581867,78638,335 30 ° 150 32,78685329,26137,050 35 ° 110 37,83884753,35742,983 35 ° 130 36,49187779,91043,726 35 ° 150 35,15091071,97844,520 This gives the data of the tests carried out in different angles of the blades of 20º, 25º, 30º and 35º and with different window openings of 110 , 130 and 150 mm in each case. As can be seen, for example, at an angle of the blades at 30º and at a window opening of 150mm, the increase in flow is noticeable and the required power decreases. 5 BRIEF DESCRIPTION OF THE FIGURES FIGURE 1 shows, in section, a possible execution in which the variation of the air flow generated by the turbine is obtained by varying the angle of the blades and thus the main elements of the device are observed and Thus we find the nozzle (1), the 10 nozzles (2), the window (3), the baffles (4) and (5), the nozzle actuator (6), the transmission of the nozzle (15) the grid of the main suction channel (7) the blades (8) the axis of rotation (9) of the blades, the eccentric axis (10) of the blades, the circular perimeter channel (11) where the end of the eccentric axis of the blades, the turbine actuator (12) the turbine transmission (13) turbine shaft (14) 15 FIGURE 2 shows, in schematic the microprocessor (16), the connections With the actuators (17), interface (18) for data entry, memory (19), connections for obtaining data from external sources (20) sensors (21) arranged in the sprayer itself. DESCRIPTION OF AN EXECUTION MODE OF THE INVENTION It is intended here to describe a mode of execution of the invention that is not unique but merely explanatory in such a way that those executions that are still different from the scope of the present protection will be covered by the scope of protection of the present. exposed here, share the claimed technical solutions. The purpose of the invention is to optimize the spraying work by adjusting the required air flow to avoid product drifts or insufficient product penetration, and configuring the sprayer so that the required air flow is optimally obtained with the consequent saving of energy costs. The sprayer with which an embodiment of the invention is to be explained is of the type comprising at least one turbine, a nozzle, at least one deflector that directs the air flow to an outlet window, and a series of 30 product dosing nozzles arranged in the area of influence of the outlet air stream. In the proposed sprayer, the determination of the necessary air flow takes place through a processor and takes into account a series of parameters, and the regulation of the air flow is produced by the combination of the configuration of two elements of the sprayer, which in this case is the configuration of the turbine by controlling the position of the turbine blades and the configuration of the window which, acting together, obtains precise control of the output air flow that disperses the product to be sprayed, and an energy optimization. However, the variation of the output air flow is not directly proportional to the variation of the window opening or to the variation of the position of the blades, nor is it arithmetic or geometrically progressive, but for each required air flow, a certain turbine and window configuration will be necessary for the sprayer to behave optimally. The intended device comprises: 1. - Means for determining the adequate air flow, which in turn comprise: a) Information entry system comprising: 15 a.  Interface (18) for the manual introduction of parameters related to type of crop, type of treatment, type of pruning, volume of vegetation per unit area, dose of treatment, atmospheric conditions, vehicle speed or nozzle relief among others. b.  Means for recovering parameters stored in memory (19). 20 c.  Means for obtaining parameters from external sources (20), such as meteorological data. d.  Sensors (21) arranged in the sprayer itself. b) Memory (19) for the storage of information. c) Processor (16) for the execution of the procedures for calculating the air flow, 25 although in an alternative execution the determination of the air flow can be carried out by consulting a data library. d) Means for recovering from memory (19) data on optimal sprayer configurations for each air flow although in an alternative execution the optimum configuration can be carried out by performing mathematical calculations. 2. - Turbine with adjustable blades. 3. - Adjustable window (3). Four. - Means to adapt the configuration of the sprayer to the configuration determined as optimal that comprise: 35 Means to vary the position of the blades which in turn comprise: a.  Turbine actuator (12). b.  Circular perimeter channel (11). C.  Eccentric shaft of the blades (10)d.  Turbine transmission (13) Means for varying the window opening which in turn comprise: e.  Nozzle actuator (6) f.  Nozzle transmission (15) 6. - Means for knowing the position of the blades comprising position sensors 5 arranged in the turbine actuator (12) and what we call blade sensors, although in an alternative embodiment the position of the blades can be known by the combination of the data related to its last known position and the movement data of the turbine actuator. 7. - Means to know the opening of the window comprising sensors in the actuator of the nozzle (6) and which we will call window sensors although in an alternative execution the configuration of the window can be known by combining the data relating to its last known position and the movement data of the nozzle actuator. 8. - Means to coordinate the movement of the blades and the nozzle to vary the opening of the window and that they comprise. 15 a) Processor (16) to calculate the movement necessary to bring the blades and window to the optimum configuration based on their starting positions. b) Connections with the actuators (17). The device comprising the indicated elements behaves as follows. As an interface (18), a tablet or smartphone device can be used that allows both the introduction of information and the display of information related to the sprayer or the spraying process. The processor (16) is preferably located in the sprayer, in a protected area. The memory (19) for the storage of information, the means for recovering the memory of 25 data on optimal configurations of the device for each air flow and the means for coordinating the flow are also preferably located in the sprayer. blade movement. This is not the only option since the technology allows several elements to be connected in such a way that for example the data could be found stored in the cloud or in an external device of the sprayer, and the microprocessor could be located elsewhere and found connected to the other elements Through the interface and the rest of the means to enter information, the necessary parameters are entered for the calculation of the air flow required for the specific spray intended. Once the necessary air flow has been determined by the processor (16), either by consultation in the data library or by calculation through the appropriate formulas, the optimum configuration of the sprayer is determined, that is, the position of the blades (8) than incombination with the opening of the window (3) achieves the desired flow at a lower level of consumption. To do this, the values of the required air flow are contrasted with a library of configurations until the one corresponding to the required flow is found. Alternatively, it could also be calculated although it is considered safer to take the 5 test data already contrasted. Once an optimal configuration of the sprayer is determined, it is necessary to adapt the sprayer to such configuration for which the movements to be performed are calculated by taking the blade and nozzle starting configurations. The starting positions of blades and window are well known by the nozzle and turbine sensors or they can be calculated taking the last known position as data and taking into account the movements executed later by the respective actuators. In case of opting for the sensors, these are not found in the blades or in the nozzle but in the respective actuators thus favoring the correct and lasting calibration thereof. 15 Calculated the movements to be performed, the means to coordinate the movement of blades and nozzle that govern the turbine and nozzle actuators, activate them until each of them reaches its predetermined optimum position. At any time during the spraying operations, the user can reverse the air flow to clean the suction channel grid of leaves and plant debris. 20 The air flow can be reversed without the need to reverse the rotation of the turbine but simply by changing the angle of attack of the blades, which is an important advantage.
