Spraying device for liquid means of chemical treatment with replaceable liquid subsystem and spraying systems on the basis thereof

A liquid subsystem for use in a spraying device for liquid means of chemical treatment, mounted on an unmanned vehicle, which liquid subsystem comprises:

• a reservoir for liquid means of chemical treatment, made in a form of a bag, suitable for extruding liquid therefrom under an external overpressure, wherein the reservoir is provided with an outlet channel, and comprising at least one liquid hose, connected to the reservoir and provided with a lock valve,
• wherein the liquid subsystem B is designed as an entirely replaceable device, further comprising
• a gasbag capable of transferring said external overpressure to the liquid in the reservoir, wherein said external pressure is adjustable;
• and
• a manifold with one or more outlet ports, which is connected to the outlet channel of the reservoir through a manifold channel,
• wherein each liquid hose at one end is hermetically connected to one of the manifold outlet ports, and at the other end is provided with a lock valve, which is closed in a disconnected state
• wherein said liquid subsystem further optionally comprises a contactless tag, made as a barcode, two-dimensional code or as a contactless radio frequency tag,
• wherein the contactless tag contains read-only information comprising a unique identifier of the liquid subsystem, and/or date of manufacture, and/or warranty expiry date, and/or designation of compatibility with various liquids, and/or designation of maximum operating pressure, and/or number of provisioned cycles of use,
• wherein the contactless tag optionally contains variable indicators of the liquid subsystem, and
• wherein variable indicators of the liquid subsystem optionally comprise an identifier of the used liquid type, and/or the impermeability status of the liquid subsystem, and/or a counter for the cycles of use.
