A portable, battery-powered liquid sprayer is operable to eject liquids. The sprayer includes a power unit including a base having a motor housed therein. The sprayer further includes a sprayer tank including a reservoir, an outlet fluidly connected with the reservoir, and a pump fluidly connected with the reservoir and the outlet. The sprayer tank is configured for selective engagement with the power unit. When the sprayer tank engages the power unit, the motor is operable to selectively drive the pump to pump liquid from the reservoir for ejection through the outlet.

A rotating atomizer device for the correction of eventual separations that random variations cause in the final result of the phytosanitary treatment so the application of the chemical products is done completely in agreement with what has been prescribed by the agronomic professional, achieving a greater efficiency of the phytosanitary spraying process. The technical information generated by the manufacturers of the agrochemical products regarding the physical characteristics of the phytosanitary chemicals; information regarding wind speed and direction, ambient humidity and temperature generated by a meteorological center and mounted in the spraying vehicle; information regarding the geo referential position, the speed and direction of the vehicle generated by a GPS type device mounted in the spraying vehicle; the information generated by the acceleration and magnetic field sensors, gyroscopes, flowmeters, spray liquid temperature sensors, rotation speed of plates sensor, magnetic analogic sensors for measuring angular positions.

A blower spray device is provided having a housing which comprises an electrically driven blower and a spray nozzle, and having a liquid supply line opening into the spray nozzle. The housing has a funnel-shaped intake channel and a tubular blow-out channel, and an electrical valve is provided in the liquid supply line to activate and deactivate the liquid supply to the spray nozzle. An electronic controller having a regulating unit for the electric blower is further provided to adjust the air flow velocity.

A rotating atomizer device is provided that allows the correction of eventual separations that the random variations (of climatic and/or environmental nature) may cause in the final result of the phytosanitary treatment so that the application of the chemical products is done completely in agreement with what has been prescribed by the agronomic professional, achieving a greater efficiency of the phytosanitary spraying process.

Fluid delivery systems for use with power tools are provided. A fluid delivery system can include a reservoir configured to contain fluid; a manifold including a plurality of nozzles configured to be disposed at an airflow outlet of the power tool, the manifold being in fluid communication with the reservoir; a pump configured to supply fluid from the reservoir to the manifold to dispense the fluid through at least some of the plurality of nozzles; and an attachment element configured to selectively couple the manifold with the airflow outlet of the power tool.

An adapter system for transforming an electric backpack into a sprayer for pesticides and disinfectants is disclosed, the adapter system comprising a reservoir in fluid communication with a sprayer, the reservoir to retain a liquid. One or more supply lines deliver the liquid to the sprayer having a blower with a handle portion including a first side to receive a conduit in fluid communication with a nozzle adapter and a nozzle to emit a mist therefrom. A power supply is in electrical communication with the blower to supply power thereto to provide a portable sprayer system.

The unmanned sprayer apparatus according to the present invention includes a vehicle body of the unmanned sprayer apparatus that moves automatically in a greenhouse including a first rail and a second rail installed on flat land, and a controller configured to control the vehicle body to be switched and moved between the first rail and the second rail while the vehicle body travels on the flat land. The controller is configured to travel the vehicle body rearward on the first rail and when a front end of the first rail is detected, stop the vehicle body, to move the vehicle body laterally toward the second rail and when a front end of the second rail is detected, stop the vehicle body, and to align the vehicle body in a direction of the second rail and then dock the vehicle body to the second rail.
