An agricultural vehicle comprises a left frame and a right frame. A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. One or more satellite navigation receivers are associated with beam to determine a position and an attitude of the beam. In on configuration, at least one row unit suspended from the beam, where each row unit has a respective planting device with an adjustable position in one or more dimensions with respect to the beam for precise application or variable application of seeds within the rows or field.

A LIDAR system is used to 3D image an aerosol plume that is being applied to vegetation. The digital map is updated in real-time based on current LIDAR data. The application of the aerosol plume is continually adjusted to keep the aerosol plume within a predetermined location.

Disclosed is a spraying unit intended for spraying a liquid onto vegetation and including: a nozzle formed by a tube, a rotatable atomizer, and a fan generating a carrying air flow around the atomizer, a drive system, and a transport unit for transporting the liquid to the atomizer, which is capable of breaking the liquid up into droplets. The nozzle encloses a body surrounded by the carrying air flow and including a rotatable portion formed by the rotatable atomizer, the rotation of which causes droplets in the carrying air flow to be propelled, preferably in a direction substantially perpendicular to the longitudinal axis. Also disclosed is a compact spraying module including such a unit and to a spraying and control system including a plurality of such modules.

The present invention relates to a system for spraying a product, notably a plant-protection product, comprising product spray nozzles (10) and airflow generating means (110), characterized in that the airflow generating means comprise an outlet (112) in the form of an annular slit designed to generate an airflow (102) in the form of a continuous tubular curtain of air enclosing the jets (12) emanating from the spray nozzles (10) and that the sprayed product cannot cross.

A method and an apparatus for the delivering of liquid mixtures of phytosanitary products is disclosed, equipped with a pneumatic liquid mixture atomization system which includes a fan for generating a carrier airflow through at least one diffuser with a conduit tapering towards a reduced section, and at least one delivery nozzle of the liquid mixture within the diffuser. The nozzle is provided with a delivery end arranged in a first delivery position within the airflow near to the reduced section and at least a second delivery position located downstream of the reduced section, where the airflow has a lower speed compared to the first position, and a controller selecting the first delivery position and the at least a second delivery position alternatively depending on a desired condition of reduction of drift effect the droplets of phytosanitary liquid.

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.

An agricultural sprayer includes at least one nozzle configured to receive a liquid and direct atomized liquid to an agricultural field in a dispersal area. A thermal imager is operably coupled to the agricultural sprayer and has a field of view behind the agricultural sprayer. The thermal imager is configured to provide an indication of a thermal reaction of the agricultural field in response to application of the atomized liquid. An output of the thermal imager is used to characterize operation of the at least one nozzle.

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 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.

The purpose of the present disclosure is to provide a method for application of products in liquid or semiliquid state, such as chemicals for agricultural use and the like, using a rotating atomizer device, in such a way that the drops shall fall downwards in the form of fog over the crops due to the action of the force caused by its mass and gravity, in addition to the eventual momentum that centrifugal effect of the rotating parties that generate the drops may provide, wherein the method includes the following steps: individually regulate the voltage for the speed of the engines of each rotating atomizer device, modifying the parameter of the power supply of the engine to ensure that the speed of each rotating atomizer device is the correct one, measure the speed of the engine under its control and correct any deviation or separation from the programmed operating values.
