A boom for a sprayer vehicle includes a fluid-carrying medium; at least one nozzle fluidly coupled to the fluid-carrying medium; and at least one unmanned aerial vehicle tethered to the fluid-carrying medium. The at least one unmanned aerial vehicle includes a plurality of fans, and the nozzle is arranged to discharge material through a fan. Related methods and sprayer vehicles are also disclosed.

An apparatus, system, and method for providing a non-linear fluid stream into an environment for cooling purposes are disclosed. Such an apparatus includes a body portion and a nozzle, the nozzle being adapted to direct water into the environment. Such an apparatus may include a body portion having a flow channel defined therein for gas flow therethrough; and, a nozzle operatively disposed within the flow channel; said nozzle adapted to direct a liquid therefrom; wherein the channel and the nozzle are operatively disposed relative to each other so that a gas flowing through the channel and the liquid are combined into a fluid stream directed from the apparatus into the surrounding environment.

A spray head for an agricultural sprayer, the spray head including a fan with a central axis, the spray head also including dual liquid manifolds coaxial about the fan's central axis, each manifold having a plurality of spray nozzles positioned to be capable of spraying liquid into air exiting the fan, and each manifold having a liquid inlet and a liquid outlet so as to permit individual control of liquid through each manifold.

An electrically powered portable liquid cold fogger that includes a main housing and that when used in conjunction with an electric motor, a self-feeding tentacle pumping spinning element, a tentacle feed tube, air screw, and air flow focusing shroud, is able to pump, fog, and dispense, low and high viscosity fluid in the forward direction.

Spray nozzle systems and methods of use are described herein. The spray nozzle system may include a stationary tube, a rigid rotor, and a sub-medium supply source. The stationary tube may be in fluid communication with a pressurized air source. The substantially rigid rotor is in fluid communication with the pressurized air source. The substantially rigid rotor includes a substantially rigid conduit that is in fluid communication with the passages of the stationary tube and the rotor. A portion of the conduit is substantially arched such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis. Pressurized air ejected from the outlet produces directional components of the pressurized air in the direction of rotation about the rotor axis; and during use, the pressurized air rotates the rotor and sucks sub-medium from the sub-medium supply source into the stationary tube passage.

A product applicator is designed for attachment to an outlet discharge tube of an air blower, and includes an adapter nozzle assembly and product storage container. The adapter nozzle assembly is located at a distal end of the blower tube, and includes a substantially hollow elongated housing and a discharge nozzle located inside the housing. The housing has a discharge end and a connecting end adapted for being arranged inline with the discharge airstream supplied by the blower. Suction and supply hoses cooperate to automatically transfer product from the storage container to the discharge nozzle. From the discharge nozzle, the product is broadcast outwardly from the operator to a surrounding area.

A fluid dispersal node is disclosed that includes one or more fluid outlets, an electromechanical valve, one or more hardware processors, hardware memory, a hardware wireless communication module, an antenna, and a fluid-tight, substantially radio frequency (RF) transparent enclosure. The valve is disposed in the node, and controls fluid flow to the outlets. The processors, in turn, control the valve. The wireless module receives instructions for operating the valve and forwards those instructions to one or more of the processors and the memory. The processors, memory, wireless module and antenna are disposed within the RF-transparent housing. In some embodiments, the antenna is disposed on a riser associated with the node outside the enclosure. In other embodiments, the antenna is disposed in a fluid line connected to the node.

Spray apparatus and uses thereof are described herein. A vacuum spray nozzle apparatus may include a first tube in fluid communication with a fluid source, a rotor coupled to the tube, a conduit in fluid communication with the passages of the first tube, and a second tube coupled to the conduit, the second tube being in fluid communication with a vacuum source. The rotor is in fluid communication with the pressurized fluid source. The conduit is substantially arched or angled such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis, and when pressurized fluid is ejected from the outlet, during use, rotates the conduit. The vacuum spray nozzle apparatus is configured to remove components from a material through the second tube when a pressure of the system is reduced using the vacuum source.
