A method of using a system to apply liquid over a selected area includes providing a source of liquid, a first tube for transporting liquid from the source through the system, a connector, a check valve and a spray device. The connector includes a projection extending into the first tube. The projection has an inlet in fluid communication with the first tube. The connector further includes an outlet and a passageway in fluid communication with the inlet of the projection and the outlet of the connector. The check valve has an inlet in fluid communication with the outlet of the connector and an outlet. The check valve is operable to permit the passage of liquid from the inlet to the outlet upon pressurization of the liquid above a threshold pressurization level. The method includes the steps of introducing an amount of liquid to be applied to the selected area from the source of liquid to the first tube at a pressure below the threshold pressurization level of the check valve and providing pressurized liquid through the first tube to pressurize the liquid in the first tube above the threshold pressurization level of the check valve, thereby transporting liquid from the first tube, through the connector and the check valve and through the spray device in response to pressurization of the liquid. The liquid may be ozonated water.

A multipurpose machine for cultivating trees, comprising an inverted U-shape structure that enables the machine to pass over existing trees to carry out pruning, disinfection or fruit picking tasks, provided at the bottom with wheels, driven by at least one motor that autonomously facilitates the movement thereof, and respective upper frames that telescopically couple to each other, being driven by respective cylinders to move the portion of the structure on the right with respect to the one on the left in order to vary the width of the machine. Likewise, the machine has the ability to raise or lower the upper structure of the same to adapt it to the height of the trees to be cultivated.

For each of a plurality of spray nozzles of an autonomous agricultural vehicle, a set of instructions provided by the autonomous agricultural vehicle to the spray nozzle is accessed. Each instruction in the set is generated by analyzing a respective image of a portion of a geographic area captured by the autonomous agricultural vehicle. A spray performance of at least one spray nozzle from among the plurality of spray nozzles is identified as an outlier by analyzing the sets of instructions respectively provided to the plurality of spray nozzles. An action with respect to the at least one spray nozzle identified as the outlier is performed. The action may be to place the vehicle in fallback state in which a targeted spray may be switched to broadcast spray.

An agricultural sprayer assembly includes a wheeled carriage, a chassis, and a spray delivery system. The wheeled carriage has a number of adjustable support legs (e.g., four), each formed of hydraulically coupled and actuated upper and lower leg sections or members. The chassis is supported on the wheeled carriage, at an adjustable clearance height defined by the operational height of the support legs. The spray delivery system includes a spray boom coupled to a boom support, and an actuator coupled to the boom support and the chassis. The actuator is configured to adjust the height of the spray boom with respect to the clearance height of the chassis.

A system and method are provided for subvehicularly accessed treatment of ground surfaces about a rail track occupied by a rail vehicle. A mobile treatment unit having a propulsion mechanism for subvehicular passage between the rails occupied by the rail vehicle includes a dispensing portion for expelling a treatment material therefrom onto regions of the ground surface about the rails. The mobile treatment unit is maneuverable between the rails and maintains height clearance for unobstructed passage beneath the occupying rail vehicle. At least one sensor unit is coupled to the mobile treatment unit, which acquires environmental feedback data about the mobile treatment unit. A control unit is operably linked to the mobile treatment and sensor units, and receives the environmental feedback data. The control unit controls actuation of the mobile treatment unit responsive to the environmental feedback and/or a maneuver control command.

A fixed spray application system generally includes tubing, one or more spray heads, one or more brackets, one or more connectors and one or more fluid reservoirs. One or more of the spray heads may be suspended from a tube below one of the connectors and below one of the reservoirs. A tube may extend from below one of the reservoirs to another spray head supported by one of the brackets. In use, the system may be suspended from trellis wires in an agricultural field. Water, pesticides or other liquids are supplied to the system through the tubing. The size of the reservoirs and the volume of tubing can be selected to hold the desired amount of liquid for a given application. After the system is primed with liquid, the tubing is connected to a source of pressurized air. The air is supplied to the system at a sufficient pressure so as to force the liquid from the system through the spray heads.

An intelligent air-assisted spraying device for orchards includes a traction mechanism, a spaying system, a collecting system, and a processing-controlling system. The traction mechanism is provided with a spray tank. The spaying system includes a main body connected to the spray tank and multiple spraying tubes, first ends of the spraying tube are communicated with the main body, and second ends of the spraying tubes are capable of rotating. The collecting system is configured to collect a contour and a volume of the canopy, and branch and leaf density of a fruit tree. The processing-controlling system is configured to obtain multiple spraying areas, calculate an air outlet angle of each spraying tube, and control a rotation of the second end of each spraying tube according to the air outlet angle. The device can adjust the spraying direction of each spraying tube, and the quality of pesticide application can be improved.

A system for irrigating an agricultural field includes a high-clearance vehicle (e.g., a sprayer vehicle) and a hose configured to connect an external water source to the high-clearance vehicle while the high-clearance vehicle traverses the agricultural field. A method for irrigating an agricultural field includes connecting an external water source to a high-clearance vehicle by a hose, and dispensing water from the nozzles of the high-clearance vehicle while the external water source remains connected thereto and while the high-clearance vehicle traverses the agricultural field.
