An arrangement introduced into a motorized nebulizer equipped with a pneumatic nozzle for generating cold drops, which allows for the high efficiency of the application through the formation of a droplet spectrum within the range of sizes recommended by the World Health Organization (WHO) for the control of insects, in particular, mosquito vectors of human diseases, in flight, which is a spectrum with a median volumetric diameter (MVD) of less than 30 microns (μm).

A treatment system for spraying treatment fluid onto plants in a field is described. The treatment system includes a configurable treatment mechanism including an array of nozzles and valve assemblies coupled into manifolds, and manifold assemblies. The nozzle comprises a nozzle housing and an insert assembly contained within the nozzle housing. When coupled, a top casing including a fluid inlet and a bottom casing including at least one fluid outlet form the nozzle housing. The insert assembly comprises at least one nozzle insert to fluidically couple the fluid inlet and the fluid outlets such that fluid entering from the fluid inlet exits the nozzle housing through the fluid outlets.

An applicator includes a spinner rotated by the parking brake output shaft of a hydrostatic transaxle driving first and second drive wheels. Material delivered from a hopper on the spinner is spread by the spinner rotating at a speed corresponding to the rotating speed of the drive wheels. Liquid is sprayed by either a trim nozzle intermediate sides of the frame or broadcast nozzles adjacent the sides of the frame. A spray lever is pivoted to slide a slide linkage from an upper position to a lower position abutting with a biased actuator of an on/off valve, with the spray lever and a spinner gate opening lever operable at the same time with just one hand. During transport, a front bumper is received in a horizontal leg of an L-shaped slot and a cutout in an arm pivotably mounted to a stop in which the L-shaped slot is located and in a locking position. A locking pin is inserted through apertures in the arm and the stop in the locking position.

An agricultural vehicle is provided herein that includes a chassis operably coupled with a powertrain control system. A boom assembly is operably coupled with the chassis. One or more nozzles is positioned along the boom assembly. A flow control assembly is configured to selectively dispense an agricultural product from a tank through the one or more nozzles. A controller is operably coupled with the powertrain control system and the boom assembly. The controller includes a processor and associated memory with the memory storing instructions that, when implemented by the processor, configure the controller to receive instructions to accelerate or decelerate the vehicle and alter a flow rate of the agricultural product through actuation of the flow control assembly in response to receiving instructions to accelerate or decelerate the vehicle.

A continuously variable nozzle system includes a nozzle body (5) with an inlet and an outlet. A conduit is defined between the inlet and the outlet by a series connection of components which includes a flow meter (10). The flow meter (10) has a chamber (83) with internal helical splines (82) that are configured to interact with a spray liquid passing through the chamber (83) and create a cyclone-like effect. A sphere (52) is located inside the chamber (83) for free movement along a circular path (106). A sensor is located outside of the chamber (83) and configured to detect motion of the sphere (52) and generate an output (9) signal in response to detected motion.

A system for spraying plants comprises a location-determining receiver for estimating a position of a sprayer with respect to one or more rows of plants. A distance sensor is arranged to measure a distance between a nozzle assembly and a plant row segment. A guidance module is adapted to align the nozzle assembly with a target path between the rows of plants, such as a centered path between the rows, or offset between the rows of the plants. A first nozzle is targeted toward a first zone with respect to the plant row segment based on a first spray pattern of the first nozzle. A second nozzle is targeted toward a second zone with respect to the plant row segment based on a second spray pattern of the second nozzle. A nozzle selection module for selecting automatically a first nozzle or a second nozzle based on maximum coverage of a target zone around the plant segment based on the first zone, the second zone, and the measured distance.

A variable width agricultural applicator is provided. The variable width agricultural applicator is attachable to a boom to apply a liquid to a crop in rows. The variable width agricultural sprayer includes a drop tube and a splitter downstream of the drop tube. The splitter is fluidly connected to the drop tube. A pair of flexible delivery tubes is fluidly connected to the splitter. Each one of the pair of flexible delivery tubes has a predetermined bend.

A portable pesticide application equipment with accurate application, which includes a pesticide tank. Rollers are arranged at the bottom of the pesticide tank. An inclined pesticide guide plate is arranged below the filter. A side connector is arranged at one side of the pesticide tank. The side connector is connected with a long hose. The long hose is connected with a pesticide discharging device. The pesticide discharging device includes a pesticide control box, two sides of which are hinged with a first iron handle and a second iron handle. A first nozzle is connected with the bottom end of the first iron handle while a second nozzle is connected with the bottom end of the second iron handle. The upper end of the first iron handle is inserted into a first support rod while the upper end of the second iron handle is inserted into a second support rod.

Embodiments include individual physical spray nozzles that have passageways inside to combine fluids that flow out of the spray nozzles. The nozzles have at least two valves that are opened and closed in an interleaved manner. The nozzles have multiple outlets. Such nozzles are mounted on a variety of implements including agricultural or industrial spray booms.

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.
