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 robotic orchard spraying system having autonomous delivery vehicles (ADV), each autonomously delivering an amount of a premixed solution over a non-overlapping path verified by a forward-looking sensor, video, or both. Also, a mobile control center, configured to wirelessly inform the autonomous delivery vehicle of the path within the areas and to confirm that the autonomous delivery vehicle is following the path within the area. Additionally, a mapper vehicle generates the path within the area, the mapper vehicle being configured to communicate information about the path and the area to the command center. The mapper vehicle senses the path with a forward-looking LiDAR sensor, and senses the area with a GPS sensor. Moreover, a nurse truck has a reservoir of premixed solution for replenishing a tank of the ADV. ADVs and the control center communicate over a radio network, which may be a mesh network, a cellular network, or both.

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.

A spray bar injector including a spray bar defining a longitudinal axis and including a fluid inlet and a plurality of spray outlet orifices spaced apart longitudinally in a direction along the longitudinal axis. A check or spray valve is operatively connected to each spray outlet orifice. A master valve is in fluid communication with the fluid inlet, operatively connected to divert flow from the fluid inlet into a first passage and block flow into a second passage in a first position to open the check valves and issue a spray from the spray outlet orifices, and to divert flow from the fluid inlet into the second passage and block flow into the first passage in a second position to close the check valves and block issue of spray from the spray outlet orifices.

Systems and methods of the present disclosure include the use of a tracer in agricultural spray solutions, and preferably a metal tracer, to determine if off-target drift of an active ingredient (AI) is based on drift caused during application or volatility of AI after application.

The agricultural sprayer includes a base with two vertical guides fixed thereon and carriages mounted on and capable of traveling along said guides. A ducted fan is turnably mounted on axles between the carriages. The inner surface of the fan duct is equipped with nozzles connected to a liquid container. One of the carriages consists of two parts: the first and the second one, with the second part capable of moving relative to the first one. The first and the second parts of said carriage have a duct-swinging crank-rocker mechanism mounted thereon. Said mechanism is configured for setting the inclination angle of the fan duct and adjusting its oscillation amplitude.

The automatic traveling method includes: causing a sprayer 1 to travel automatically along a target route in a field; executing temporary stop processing; and executing stop reservation processing. The temporary stop processing is processing to stop the sprayer at a current position in a mode in which travel of the sprayer can be resumed in the case where a temporary stop condition is satisfied during automatic travel of the sprayer. The stop reservation processing is processing to cause the sprayer to travel and thereafter stop the sprayer in a state where the travel of the sprayer can be resumed in the case where a stop reservation condition is satisfied during the automatic travel of the sprayer.
