    Spray device for phytosanitary substances
    The present invention refers to a device for spraying substances for phytosanitary use that has remarkable characteristics of novelty and inventive activity.
    The devices for spraying phytosanitary substances are widely used in the fields of agriculture and gardening, among others.
    Within this type of devices, personal devices are known, comprising a deposit of phytosanitary substances carried by an operator (for example, a backpack type tank), a sprayer with a pump (usually located in the tank) and a a lance to apply the substance to be sprayed at a distance. One of the disadvantages of this type of devices is the short range of the same, since it corresponds to that of the spray lance. Also, the deposit, having to be carried by an operator, is necessarily small. Finally, the deposit also prevents the operator from accessing remote and hard-to-reach sites.
    Devices attached to a land vehicle, such as a tractor, are also known. These devices have the advantage that a larger reservoir can be available and allows large areas to be sprayed. In these devices, the tank is usually located in the rear wall of the land vehicle, where a folding arm is usually located to spray the substance. This type of device has the advantage, with respect to personal devices, of being able to efficiently spray large surfaces. However, they cannot access hard to reach sites either. In addition, the entire system, especially the folding arm, jeopardizes the stability of the land vehicle or tractor, since they make a lever with respect to the center of gravity of the same that can cause the land vehicle to overturn.
    It is also known, for example from the company Drone Volt, to provide a conventional drone with a spray (not tied). A drawback of this application is that the drone cannot carry a large amount of substance, so it can only be used for specific applications, such as the removal of wasps in trees.
    On the other hand, unmanned vehicles of type tied (hereinafter "drone tied") are known. These tied drones comprise a cable that holds them to a ground station, limiting the scope of their flight and making them slaves of a land port or base in such a way that they do not constitute an independent vehicle. It is known that said cable is the power supply cable. These drones are used for applications in which the drone must be in the air for a long time in the same position, for example, applications in which the drone carries a camera, in cultural and sporting events. In these applications, the attached drone replaces a crane or a removable type structure.
    It is an objective of the present invention to disclose new spray devices that do not have the aforementioned drawbacks. More specifically, the present invention discloses a device that simultaneously allows spraying large surfaces and reaching remote places. In particular, the present invention discloses a device for spraying substances of phytosanitary use of the type comprising a reservoir and a nozzle for the emission of a substance for phytosanitary use, the reservoir and the nozzle being connected by a hose for conducting the substance of phytosanitary use that feeds the nozzle from the tank, in which the nozzle is located in an unmanned aerial device and because the tank is not fixed to the aforementioned unmanned aerial device, such that the unmanned aerial tank does not support The weight of the deposit.
    The fact that the unmanned aerial device must not support the weight of the tank increases the spray autonomy of the spraying device, allowing a larger tank to be used and thus being able to spray a greater amount of substance compared to a situation in which the tank it was transported by the unmanned aerial device. Consequently, the present invention allows spraying a larger land area.
    In addition, the fact that spraying is carried out from an unmanned aerial device facilitates access to heights or distances that are difficult to access.
    On the other hand, the present invention makes it possible to avoid the use of heavy structures that were necessary to place in the tractor vehicles, such as folding arms.
    In an embodiment of the invention, the device may comprise an energy source and an electric cable that feeds said unmanned aerial device with electrical energy from the energy source, the energy source not being fixed to said unmanned aerial device, in such a way that the unmanned aerial device does not support the weight of said energy source. In this case, the autonomy of the aerial device is unlimited as long as the power source can power it. Being the autonomy of the unlimited air device, the present invention allows the realization of tasks that pulverize the total amount of substance of the deposit in a single session, that is, without the need to stop the task by finishing the energy of the unmanned aerial device .
    Preferably, the length of the power supply cable is less than the length of the conduction hose of the phytosanitary substance. In this way, the unmanned aerial device never stretches from the conduction hose and the risk of its rupture and the phytosanitary substance is spilled creating a dangerous situation for the users due to the nature of the substance.
    The device may optionally comprise an unmanned aerial device control interface, said interface being optionally arranged in the cabin of said land vehicle.
    The tank may, optionally, be arranged in a land vehicle, such as an agricultural tractor.
    On the other hand, the energy source may also be, optionally, arranged in a land vehicle, such as an agricultural tractor.
    In another embodiment of the invention, the deposit may be a backpack type deposit.
    The unmanned aerial device may be an unmanned aerial vehicle, for example, a drone, either of a specific design or conveniently adapted.
    In the present application, the term "substance for phytosanitary use" includes both phytosanitary substances and other substances of more or less common use that are used for such purposes in agriculture, gardening, etc.
    For better understanding, some drawings of an embodiment according to the present invention are attached by way of explanatory but not limiting example.
    Figure 1 shows an embodiment of the spraying device according to the present invention in which the tank and the energy source are arranged in an agricultural tractor.
    Figure 2 shows an embodiment of the spraying device according to the present invention in which the tank constitutes a trailer intended to be connected to a land vehicle.
    Figure 3 shows the embodiment of Figure 2 with the trailer connected to an agricultural tractor.
    Figure 4 shows an embodiment of the present invention in which the tank is a backpack type tank.
    As can be seen in Figures 1 to 4, the device for spraying substances for phytosanitary use according to the present invention comprises an aerial device, in particular, an unmanned aerial vehicle connected to a tank -2 through a hose -12-of conduction that allows to pulverize a phytosanitary substance of the deposit -2-through the nozzles -11-, -11'-of emission of phytosanitary substance of the vehicle -1-unmanned aerial. In addition, the unmanned aerial vehicle is powered electrically thanks to an electric power cable that connects it to an electric power source.
    In Figure 1, the power supply comes from an agricultural tractor -3 that comprises a control interface (not shown) of the unmanned aerial vehicle arranged in the cabin.
    On the other hand, in figures 2 and 3 the power supply comes from a trailer that acts as a tank -2-and that is connected to an agricultural -3 tractor. The agricultural tractor -3 of Figure 3 also comprises a control interface (not shown) of the unmanned aerial vehicle arranged in the cabin.
    In the embodiment of Figure 4, the tank -2-is of the backpack type and is intended to be carried by a person while traveling on the ground to be sprayed. In addition, said embodiment comprises an element -31- which may be intended for the control of the unmanned aerial-1 vehicle and / or for the power supply of the unmanned aerial vehicle -1. In the event that the element -31-is intended solely for the control of the unmanned aerial-1 vehicle, said vehicle -1-may be electrically powered by any known means, such as batteries arranged in the vehicle itself - 1-aerial or through a third cable connected to a power supply, among others. In the event that the -1-air vehicle has batteries, an electric cable will not be necessary for its power.
    In the embodiments of Figures 1 to 3, the control of the unmanned aerial vehicle is carried out autonomously. However, in the same way as illustrated in Figure 4, said examples may comprise manual control means known as, for example, a third cable connected to a control element or a remote control element, among others.
    Although the invention has been presented and described with reference to embodiments thereof, it will be understood that these are not limiting of the invention, so that multiple constructive or other details that could be evident to the technicians of the sector could be variable after Interpret the subject matter disclosed in the present description, claims and drawings.
