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 system for dispensing multiple low rate agricultural products, includes a syringe-based agricultural product metering system, a number of agricultural product tubes, and an agricultural product metering system. The agricultural product metering system is operably connected to sources of low rate agricultural products. The agricultural product tubes are operatively connected to the agricultural product metering system. The agricultural product metering system is configured to dispense liquid low rate agricultural products at a low rate defined as below 3.7 fluid ounces per 1000 row feet.

A boom for a sprayer vehicle includes a fluid-carrying medium; at least one nozzle fluidly coupled to the fluid-carrying medium; and at least one unmanned aerial vehicle tethered to the fluid-carrying medium. The at least one unmanned aerial vehicle includes a plurality of fans, and the nozzle is arranged to discharge material through a fan. Related methods and sprayer vehicles are also disclosed.

The present invention provides an electronically controlled valve in each air distribution line for delivering product-conveying air to a boom section of an agricultural machine. The valves can be used to balance airflow between lines by controlling back pressure at the boom sections. In one aspect, an electronically controlled butterfly valve can be installed in each air line between a fan's plenum outlet and a dry product delivery meter. Each valve can be configured to allow some flow when in a closed position. This could be achieved, for example, by configuring a valve plate with a circular perimeter shape that has a smaller diameter than an inner diameter of the line or tube in which the valve plate is mounted.

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.

The invention provides a material clearing or cleaning system which can be installed on an agricultural machine to spray off, blow off or otherwise clear off agricultural product, dust, debris and/or other material from the machine. The material clearing system can comprise a piping, tubing or fluid conduits with installed nozzles which can be customized to focus a cleaning fluid, such as air or water delivered under compression, onto targeted areas of likely build-up on the machine, to clear such excess material and increase the life of the equipment. Nozzles could be fitted anywhere on the piping, for example, by piercing a nozzle into the piping in a given direction. Nozzles could also comprise goose necks for directing the fluid in various directions by reshaping the goose neck.

An agricultural plant protection machine and a diaphragm pump thereof are provided. The diaphragm pump includes a pump body including a containing cavity; a pump cover on the pump body; a diaphragm in the containing cavity, which and the pump cover surround to form a cavity; and a driving mechanism in the containing cavity. The driving mechanism includes a push rod, a coil assembly and an elastic reset member. The push rod is connected to the diaphragm and the elastic reset member. When the coil assembly is powered on and powered off alternately, the push rod makes a reciprocating linear motion to drive the diaphragm to reciprocate relative to the pump cover so as to reduce or enlarge the cavity.

A system for dispensing multiple low rate agricultural products that includes a multiple low rate agricultural (MLRA) product application device configured to cooperate with a planting equipment monitor assembly positioned to sense a seed being discharged from high speed planting equipment. Each MLRA product application device comprises a common housing for a number of low rate agricultural product input assemblies.

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.

An automated system for monitoring and treating pests in a crop field, comprising at least one trap for monitoring and identifying pests, at least one UA V containing at least one chemical or biological products; a home base for parking or storing said at least one UA V when they are not operating; at least one database server; and equipment for communicating with said at least one trap, said at least one home base, said at least one UA V and said at least one database server.
