- the spraying equipment has regulation systems that allow setting, controlling and maintaining, depending on the case, the volume of product sprayed, the volume being related to the operating pressure. If the equipment installs a constant pressure regulation system, it is necessary to constantly maintain the working speed of the sprayer if you want to keep the volume applied per hectare uniform, since the pulverized flow rate remains constant, but nevertheless maintaining Fixed working pressure has the advantage that the projection angle and spray spectrum are maintained, that is, droplet sizes.
- the machine installs a regulation system with proportional distribution, either at engine revolutions or at the advance, the volume applied per hectare is maintained constant, regardless of the speed of the machine and in this case the regulation is It performs by varying the pressure of the liquid to modify the flow rate so that it adapts to the displacement or engine speed of the equipment.
- Another possible application system is the one that allows the direct injection of the active material, called concentration proportional to the advance, in which the water and the pure or pre-mixed phytosanitary product are in independent circuits, mixing in suitable proportions according to the speed of movement of the machine

- the invention also has the object of providing a system that doses different active substances independently and very precisely in the proportions appropriate to the agronomic needs with dosage regulation based on the calculations of the control center, which has in counts the flow of clean water and optionally the speed of movement of the equipment.
- the invention also aims at injecting the previously dosed active material beyond the pump delivery area of the applicator equipment, separating the area through which clean water circulates by means of non-return valves.
- the invention thus provides a system that reduces the wear of the most sensitive components, such as the flow detector, by injecting the active materials after this element and others such as the pressure sensor, regulating valve and the like, have the possibility of presenting breakdowns.
- the invention also has the object of allowing a complete cleaning by extracting products and subsequent pumping of clean water through all the pipes, leaving them clean and empty of substances that could cause deterioration.
- the direct injection and injection system of active materials for applicators of phytosanitary products performs the dosage that must be applied, (l / ha) for each active product that is introduced into a control unit, receiving this unit of control an exact measurement of the flow of water injected by means of a flowmeter and this information, the control unit facilitates the number of revolutions to the engine of each dosing pump.
- peristaltic dosing pumps are used, which achieve great precision, taking into account that they operate at a uniform pressure, approximately at atmospheric pressure, each of the driving motors of said pumps having a revolving meter for the purpose. to guarantee the number of them and at the same time guarantee the flow.
- the doses to be applied for each active product are collected in a manifold and the assembly is injected by means of an injection pump, which operates at a constant flow and pressure rate and is configured as a totally different pump to the dosing pumps.
- the injection pumps can act in the opposite direction, recovering the remaining active product in the ducts, reintroducing it into its container.
- the invention has an alarm system when the injection required by the device is very high and the system cannot perform the application.
- the invention can incorporate a speed controller of the applicator machine, and in this case, the flow rate of the water line may be regulated by an electrovalve located next to the flowmeter, the metering pumps not then acting according to the flowmeter, the speed being set of these metering pumps depending on the speed, which in turn sets the flow rate of the water conduction, in case of having a regulating solenoid valve.
- Figure 1 corresponds to a schematic view of the basic elements that constitute the invention, relative to a system of direct dosing and injection of active materials for applicators of phytosanitary products, with dosing proportional to the flow rate.
- the mobile equipment that incorporates the system according to the invention will have the appropriate calculation and correction means so that from such a dosage the volume per unit area applied is correct.
- Figure 1a is equivalent to the previous one although in it a single peristaltic pump and control devices are used, associated to each supply duct of dosed active matter.
- Figure 2 represents a view similar to that shown in figure number 1, in which the invention performs its operation with dosing proportional to the displacement of the equipment used.
- Figure 3 shows the flow chart of the dosing and injection control routine.
- Figure 4 shows the flow chart of the general dosing and injection control routine for a dosing system proportional to the displacement of the equipment using this invention.
- Figure 5 finally corresponds to the flow chart of the dosing control subroutine for a dosing system proportional to the flow rate used by the present invention.
- the dosing system and direct injection of active materials for applicators of phytosanitary products that is recommended, is configured as a system capable of regulating the injection of pure or pre-mixed phytosanitary products to the flow of consumed diluent liquid , usually water, by the equipment from the selected application dose to generate the mixture to be applied, for example, by spraying.
- the system adapts the flow of active material injected to the flow of clean water absorbed by the application so that a constant concentration of the active materials in the applied liquid is guaranteed and, in case of having a speed sensing sensor, it is performed a regulation of both the flow of active matter and the flow of water, guaranteeing at all times an application volume such as the one recorded.
- the invention adjusts the dosage of active materials and the consumption of water to the movement of the equipment, that is, it carries out a dosage proportional to the advance.
- V volume applied per hectare
- the regulation of the flow of active materials injected is carried out by varying the rotation speed of the motors that drive the dosing pumps, it should be noted that in each dosing pump the different proportions of active materials to be injected can be regulated from the different Rotation speeds of the motors, each acting independently and always maintaining the proportion between them.
- the invention presents a dosage of the different products that can be carried out by using a metering pump with multiple admissions, which varies the proportion of the different dosed liquids, by the assembly of the components of the pump itself.
- the equipment has a series of known elements (10), configured as a tank (11) in which only the diluent liquid will be stored, usually clean water, which is extracted and pumped under pressure by means of a pump (12) which is responsible for maintaining the pressure desired by the operator, and to maintain this pressure many teams have a pressure regulation system (13), which is responsible for adjusting the pressure, often with a return flow (14), guaranteeing with these means an adjustable pressure in the liquid transport line (20), so that the flow rate is regulated according to the pressure supplied by the equipment.
- a pressure regulation system 13
- a return flow 14
- the first element placed in the invention is a flowmeter (21), which will only record the diluent liquid flow that is driven from the pump (12) of the original equipment, indicating that the signal from the flow meter is sent to the control center (34) and is the basic information for the regulation of the dosage.
- the control unit (34) regulates the rotation regime independently in each of the motors that control dosing pumps (23), preferably of peristaltic type, which when operating at atmospheric and uniform pressure (observe the connection through conduit 24 , which will be described later, of the collector 26 with the atmosphere) offer a good regulation of the flow rate by controlling the revolutions of the corresponding engine, taking into account that the engine has a system that detects the exact speed of rotation thereof that the control center uses to check and adjust the rotation of the motor by providing more or less intensity as required at each moment and at each motor, thus guaranteeing the required revolutions with great accuracy, a basic fact for precise dosing from the sensor readings installed in the equipment.
- Each pump (23) is fed with liquid from its corresponding active material tank (22), and each tank has its stopcock (35) that It allows insulating the tank from the pipes (46) when necessary, for example, when changing active material, in case a pump (23) doses several products, it will have as many inputs as it doses and will work in the same way.
- This set of pumps regulated by the control system are responsible for dosing the active materials, supplied by the ducts (46) generating at every moment the correct flow rate that through the injection system (27) is mixed with the water to form the mix to spray.
- the injection equipment receives in its manifold (26) the set of dosed active materials, and said injection equipment will be constituted by a Venturi system, or by a pump (27), as shown in figure number 1 , preferably of gears, which operates under a constant pressure and flow rate.
- a Venturi When, alternatively, a Venturi is used, it receives the set of active materials at its injection inlet, which has a non-return valve to prevent the passage of water that circulates at greater pressure to the dosing circuit, indicating that the suction created in the admission of the Venturi allows the entry of all the flow that pumps the dosing pumps.
- a pump (27) If a pump (27) is used, it will be regulated by means of a motor (30) that rotates at fixed revolutions, and that is activated at the moment when it is detected that there is a dosage.
- the flow injected by the pump (27) will also be constant and this fact requires the installation of an inlet (24) of diluent liquid, that is to say water, which joins the materials active from dosing, so that the flow of active material dosed with clean water is completed to ensure a constant flow in the injection pump, thus avoiding the entry of air into the spray circuit, ie the risk of cavitation .
- diluent liquid inlet comes from an outlet in the conduit (20) downstream of the flowmeter, and supplied through the conduit (48) which can be seen in Figures 1, 1a and 2.
- Said water inlet is controlled by an electrovalve
- the mixer (29) that homogenizes the flow of clean water with the flow of dosed active materials, and both the entry of water into the mixer as well as that of active materials, have two non-return valves (28).
- the mixer is driven by a motor (30) at constant revolutions sufficient for a suitable and homogeneous mixture regardless of the dosage and acting whenever there is dosage.
- a single motor (30) can be used for the simultaneous operation of the pump (27) and the mixer (29), the injection pump running at a constant rate at all times having only as mission the injection under pressure of the active substances previously dosed.
- a filter (31) for the liquid already mixed which in addition to ensuring that the nozzles are not clogged, performs a new homogenization of the mixture of active materials and water, which will then be sprayed, in the case represented in the figure in question by using a support bar (32) of a plurality of spray nozzles.
- a pump 23 for each tank (22) instead of using a pump 23 for each tank (22) it would be feasible to use a single pump 23a, in which case the supply lines 46 of the active material will subsequently incorporate a control element 45, such as a solenoid valve so that from the electronic unit 34 the uniform dose can be modified for all the ducts applied by said pump 23a, adapting it to the predetermined value.
- a control element 45 such as a solenoid valve
- the control system allows a complete cleaning of the same from a control panel with push-buttons, since in the first place it is possible to empty the dosing lines by recovering the active materials that remain in this area, connecting the central drain button (34) to the pump motors dosing (23) in the reverse direction, while opening the solenoid valve (38) of the "normally closed” type to allow the passage of air to the pipes to remain empty and then the application system assembly can be cleaned using the closing of the stopcocks (35) that close the passage of active materials and allow the passage of water from the same point through the ducts (47), so that exactly the entire empty area is cleaned, leaving no remains of active matter.
- the system cleans all the applicator pipes when pumping water, so that the air and any remaining active materials that may remain are expelled.
- the invention in an alternative embodiment shown in figure number 2, presents a series of additional elements (40), it should be noted that the main component that differentiates this second embodiment represented in figure number 2 with the embodiment represented in figure number 1 is a speed sensor (41), of the desired type, both encoder and radar, regulating this sensor for this embodiment the dosage of active materials, including in the conduit (20) a motorized valve that regulates the flow of water by the pressure, so as to guarantee a constant volume per hectare, whatever the speed of travel.
- an additional alarm (43) is included in the control center (34), which warns the operator in case the forward speed is excessive for the water flow, which can pump the pump (12) therefore, the regulation of the valve (42) would be totally ineffective.
- control center (34) varies its calculation process, in order to adapt the dosage to the flow rate in the first embodiment, while in the second dosage it generates an adaptation to the travel speed.
- the calculated revolutions (53) are compared with the maximum permissible value and if its value is greater than the maximum, the alarm indicator (33) is connected and the maximum speed that can be set as the revolution value (53) of the motor in question is set. give.
- the next step consists in the opening (54) of the solenoid valve (25) that allows the passage of water to the manifold (26), it should be noted that the step of verifying engine revolutions and maximum revolutions has been reflected with the reference (55 ).
- the next step consists in opening (54) of the solenoid valve (25) that allows the passage of water to the manifold (26) of the injection pump, connecting (56) the motors of the dosing pumps to the corresponding revolutions and the injection engine (30) is connected (30) for handling the injection pump (27) and / or the mixer (29) that will receive the dosed products.
- the system checks if it should continue, and if so, it restarts the control by reading the flowmeter signal again, and otherwise, the dosing and injection of active material is terminated.
- figure number 4 which reflects the flow chart for the calculations carried out by the control center for a system such as that shown in figure number 2, with dosing proportional to the advance, it should be indicated that a stage of start (60) of the process and first of all a reading of initial parameters (61) such as liters per hectare to be applied for each product, totals, etc. unchanged during application and then a reading (62) of the sensor (41) of travel speed of the equipment is made.
- a double control is then carried out, regulating on the one hand the dosage (63) and injection, as shown in figure number 5, and on the other hand regulated the water flow (65) and in both cases taking into account The travel speed of the equipment.
- the next step to be taken for the regulation of the water flow is the reading (64) of the flow meter (21) and then the flow rate (65) of the water required by the system is calculated, which is a function of the travel speed, and Compare the calculation value with the measured value.
- the required flow block has been referenced with (66) while the current required flow block has been referenced with (67) and the stage of regulating the solenoid valve by opening (68) and regulating the solenoid valve by closing with (69), indicating that the opening has been referenced with block (70) and the connection of the alarm indicator with (71).
- the calculated revolutions (81) are compared with the maximum permissible value in the block (82) and if its value is greater than the maximum, the alarm indicator in the block (83) is connected and set as the revolutions value of the motor in question the maximum that this can give, performing then the stage (84) of opening of the solenoid valve that allows the passage of water to the manifold of the valve, injection, making the connection (85) of the engines and dosing pumps to the corresponding revolutions, and the drive motor of the injection pump and / or the mixer is connected in the stage (86) that the dosed products will receive.
