An active substance supply system for an agricultural sprayer has a main liquid circuit which includes a reservoir for a main liquid and permits circulation of the main liquid, where the main liquid circuit includes one or more distribution sections which are each configured to distribute to several dispensing elements a spray liquid to be dispensed, and a feed system which is connected to the main liquid circuit and in which the main liquid is mixed with at least one separately supplied active substance to form a liquid active substance mixture, where the active substance supply system is configured to introduce the active substance mixture into the one or more distribution sections at several places.

A flow control method includes obtaining a target flow rate for extracting liquid, determining a target rotation speed of a liquid extraction apparatus corresponding to the target flow rate based on a preset association relationship between a flow rate and a rotation speed of the liquid extraction apparatus, and controlling the liquid extraction apparatus to rotate at the target rotation speed to extract liquid.

An insulated electrostatically-assisted insulated spraying extender (10) is described, which is installed on the spraying bar (100) of a spraying device and positioned adjacent to a hydraulic nozzle (20) that atomizes the spray solution, said extender (10) being equipped with an insulated internal shaft (12) for the passage of the power supply cable (30) and the placement of an encapsulated electric device (13) that feeds the induction electrode (151) surrounding the opening (21) of the hydraulic nozzle (20), causing the dielectric rupture of atomized drops, eliminating or decreasing the wetting of the induction electrode (151) and of the power supply cable (30), as well as of other electric parts that affect the efficiency and the full operation of the spraying nozzle, while hindering leakage of the electric current through cable (30) by contacting any section of the machine structure.

The present invention is to provide a system, a method, and a program for adjusting the balance of an insect killer hung from a robot that are capable to adjust the position of the insect killer. The system for adjusting the balance of an insect killer 1 hung from a robot 10 moving by a propeller 410 through a support arm 100 adjusts the balance of the insect killer 200 so that the angle between the support arm 100 and the direction of gravitational force from the robot 10 has a predetermined value or more; and adds a weight 300 to an end of the same support arm 100 as the support arm 100 in the negative direction to an angle of the predetermined value and calculates the weight 300 to adjust the balance of the insect killer 200.

A method of spraying multiple fluids from an agricultural machine includes supplying a first working fluid from a first source to a first spray nozzle, and supplying a second working fluid from a second source to the first spray nozzle. The method also includes operating at least one valve in the first spray nozzle to control flow of the first working fluid from the first source to one or more outlets of the first spray nozzle, and operating the at least one valve in the first spray nozzle to control flow of the second working fluid from the second source to the one or more outlets of the first spray nozzle. The method further includes selectively spraying the first working fluid through the one or more outlets of the first spray nozzle, and selectively spraying the second working fluid through the one or more outlets of the first spray nozzle.

The application is generally directed towards an airfoil for a fluid delivery tube. The airfoil includes a securing member operably connecting the airfoil to the tube, a fin extending downward and outward from the securing member and terminating in a tip, a shield extending inward and downward from the tip of the fin, and an air guide extending from a first end of the shield.

Meshes capable of droplet fragmentation are generally described. Inventive articles, systems, and uses thereof are also described.

The leak-proof chemical distribution system is a spray system for mounting on a vehicle, such as a truck or aircraft, for the distribution of chemicals.

The system is separated into a storage section and a distribution section.

The storage section is located within the vehicle, and thus must be leakproof. The distribution section is located outside the vehicle, thus any connections or components that may leak will not leak on the vehicle.

The present invention relates to the application of a concentrate in diluted form. Subject matters of the present invention are a device and a method for application of a concentrate in diluted form. A further subject matter of the present invention is use of the device according to the invention in the area of agriculture, in particular for treating cultivated plants with plant protection agents and/or nutrients.

A mobile agricultural sprayer includes a chemical tank that holds a chemical fluid to be sprayed at a worksite and a rinse fluid tank that holds rinse fluid. The mobile agricultural sprayer also includes a first sensor coupled to the rinse fluid tank configured to detect a characteristic of the rinse fluid within the rinse fluid tank, and, generate a first sensor signal indicative of the characteristic of the rinse fluid. The sprayer also includes a distribution system, including a fluidic pathway and a nozzle, configured to pump the rinse fluid from the rinse fluid tank along the fluidic pathway through the nozzle of the sprayer. The sprayer also includes a second sensor coupled to the fluidic pathway configured to detect a characteristic of the fluid within the fluidic pathway, and generate a second sensor signal indicative of the characteristic. The sprayer also includes a residue detection system configured to receive the first and second sensor signals and, based on the received sensor signals, determine a concentration of residue within the fluidic pathway.
