An apparatus for dispensing a treatment liquid to a respective agricultural crop, including means for diffusing the treatment liquid, which comprise means for emitting a flow of air for diffusion of the treatment liquid, in particular fan-style diffusion, and means for dispensing the treatment liquid inside the flow of air for diffusing the treatment liquid, connected with means, in particular a respective tank for containing the treatment liquid; the dispensing means including a dispensing body having an inner chamber for conveying the liquid, respective inlet opening means of the treatment liquid, and nozzle means for escape of the liquid in the flow of air for diffusion of the treatment liquid, in communication with or opening into the inner conveying chamber; the inlet into the conveying chamber being defined by a plurality of openings leading into the inner chamber for conveying the liquid.

A fluid sprayer includes a tank containing fluid therein and a nozzle assembly in communication with the tank to receive fluid therefrom and to atomize the fluid. The fluid sprayer also includes a blower assembly positioned upstream of the nozzle assembly for dispersing the atomized fluid from the nozzle assembly into the surroundings of the fluid sprayer and a discharge chute positioned downstream of the blower assembly into which the atomized fluid from the nozzle assembly is sprayed before being discharged vertically upward and into the surroundings of the fluid sprayer. The nozzle assembly includes at least one discharge port having a discharge axis oriented perpendicular to a direction of airflow exiting the discharge chute.

A fluid sprayer includes a tank containing fluid therein and a rotary atomizer in communication with the tank to receive fluid therefrom and to atomize the fluid. The fluid sprayer also includes a blower assembly positioned upstream of the rotary atomizer for dispersing the atomized fluid from the rotary atomizer into the surroundings of the fluid sprayer and a discharge chute positioned downstream of the blower assembly into which the atomized fluid from the rotary atomizer is sprayed before being discharged upward and into the surroundings of the fluid sprayer. The rotary atomizer includes a plurality of fan blades coupled to a hub. The fan blades are operable to impart rotation to the hub in response to an airflow generated by the blower assembly flowing around the fan blades.

A spray nozzle system includes a nozzle body and an adaptor coupled to the nozzle body. The adaptor has a first region and a second region angled at a non-zero angle relative to the first region. The spray nozzle system also includes a nozzle cap coupled to the second region of the adaptor. The nozzle cap includes a nozzle outlet to spray a liquid.

A liquid dispensing system that includes a carrier having a storage tank disposed thereon for storing a liquid product. A boom is coupled to the carrier and includes a distribution hose through which the liquid product flows from the storage tank and into a number of liquid placement apparatuses. Each liquid placement apparatus includes a drop assembly coupled to the boom and extending downward. A base assembly is coupled to the lower end of the drop assembly and a hose assembly extends from the distribution hose to the base assembly. A lower hose assembly is protected within the base assembly and includes a pair of dribble hoses extruding from the base assembly. The liquid product is delivered proximate to the ground surface through the dribble hoses.

A method of operating a fluid sprayer includes supplying a first fluid selected from a group consisting of larvicide, adulticide, and a barrier repellant to a nozzle assembly at a first regulated pressure. The method further includes changing the first regulated pressure to a second regulated pressure different than the first regulated pressure. The method further includes supplying a second fluid selected from the group to the nozzle assembly at the second regulated pressure.

The present disclosure provides a nozzle assembly for a spray device for the treatment of agricultural crops and includes at least one orifice for dispensing at least one treatment product. The nozzle assembly further includes, downstream of the orifice, at least one set of electrodes configured to pass an electrical signal when humidified under the effect of the spray jet. The electrodes are configured to be connected to an electronic system for detecting the electrical signal.

The present invention relates to an agricultural system for spraying an area of a cultivated field, including a spraying equipment. The spraying equipment comprises a first and a second supporting structures extending perpendicularly to the travel direction of the agricultural system when operating. The first supporting structure comprises a first array of nozzles separated from each other by a first distance while the second supporting structure comprises a second array of nozzles separated from each other by a second distance smaller than the first distance. The spatial resolution of spot sprays that may be sprayed by the second array of nozzles is higher than the spatial resolution of spot sprays that may be sprayed by the first array of nozzles when the first and second supporting structures are at the same height such that the first and second arrays of nozzles may perform respectively low and high-resolution spot sprays.

A variable-orifice spray nozzle system includes at least one variable-orifice spray nozzle including a nozzle body with a flexible nozzle orifice opening and a mechanism that controls the physical size and shape of the orifice opening. An actuator can set and change the position of the orifice control mechanism. A mount attaches to a spray boom. The actuator has a home position. A pressure sensor senses fluid pressure delivered to the nozzle body. A controller can control the actuator to set a requested nozzle flow rate and/or droplet size based upon data from the pressure sensor via positioning of the actuator. The controller tracks the actuator position relative to its home position via open loop control. A weather control system senses weather conditions and is configured to adjust the requested nozzle flow rate and/or droplet size of the controller according to sensed weather conditions.
