A retrofit dual sprayer system comprises an agricultural vehicle having a broadcast tank mounted thereon, the broadcast tank having a first volumetric capacity for holding general-application liquid chemical(s) for preventing undesirable plants from growing in an agricultural field, a selective-spot spray (SSP) tank retrofitly mounted on the agricultural vehicle, the SSP tank having a second volumetric capacity for holding specific liquid chemical(s) for treating one or more target weeds growing in the agricultural field, the second volumetric capacity greater than or equal to about 5% of the first volumetric capacity and less than or equal to about 30% of the first volumetric capacity, a spray boom attached to the agricultural vehicle, the spray boom including broadcast nozzles mounted on the spray boom, the broadcast nozzles fluidly coupled to the broadcast tank, and SSP nozzles retrofitly mounted on the spray boom, the SSP nozzles fluidly coupled to the SSP tank.

A spraying system for an agricultural sprayer includes a plurality of nozzle assemblies configured for positioning along a sprayer boom. Each of the plurality of nozzle assemblies is in communication at least one boom tubes. A nozzle controller is in communication with the plurality of nozzle assemblies, and the nozzle controller is configured to control one or more of the nozzle assemblies of the plurality to provide a targeted application of agricultural product.

The sprayer system associated with a work vehicle having a boom and a fluid source may include a spray device configured to selectively apply a fluid from the fluid source on the work vehicle to an agricultural crop. The sprayer system may further include a drop apparatus having a linkage assembly with a top portion coupled to the boom and a bottom portion coupled to the spray device. The linkage assembly may be selectively repositionable between a retracted position and an extended position to raise and lower the spray device relative to the boom along an upright reference axis.

A fluid dispenser that is arranged with rotating gimbals supporting nozzles at multiple altitudes that can rinse and remove insects from the trees without harming the fruit or the trees. A vertical standpipe connected to a water supply leads to a flexible tubing over the top of the tree, with an umbrella or parabolic frame supporting multiple conduits terminating in gimballed nozzles about the tree that can be adjusted and aimed to stream water from the water source directly onto the tree via the vertical standpipe. Each conduit supports a gimballed nozzle that can be adjusted so that the stream can be focused at the areas where insects collect.

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.

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 liquid dispensing apparatus for applying liquid products to row crops. The liquid dispensing apparatus includes a plurality of drop assemblies supported by and laterally spaced along a boom structure. Each of the drop assemblies includes dribble hoses for dribbling a liquid product onto the soil in a rhizosphere of adjacent crop rows. The drop assemblies may include a spray assembly for spraying the row crops. The dribble hoses may be supported by a base unit with positionable support brackets.

A configurable spray boom includes a boom frame that includes an upper support and a lower support that are separated from each other with respect to a vertical axis and extend parallel to a first axis. Camera frames are attached to the upper and lower supports, each camera frame including first and second supports that are separated from each other with respect to a second axis. Each camera frame has a vertical plane of symmetry. The camera frames are evenly spaced, with respect to the first axis, along the boom frame. In a first configuration a respective camera is mounted on the first support such that the respective camera is oriented in a first direction. In a second configuration the respective camera is mounted on the second support such that the respective camera is oriented in a second direction.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a nozzle includes a fluid inlet, a fluid outlet, and a rotatable member to rotate over the fluid outlet to selectively expose the fluid outlet to at least one opening to provide fluid flow from the fluid outlet through the opening. Upon the rotatable member rotating over the fluid outlet, a different number of openings is in fluid communication with the fluid outlet.

An improvement to a roadside sprayer fixates spray nozzles on a registration plate. The registration plate may include integral tabs depending on the application. Inclination of the tabs is adjustable to place streams and droplets in a desired swath coverage. With the nozzles rigidly mounted onto the plate, the entire plate is nutated. The use of the registration plate in a spray unit creates a uniform nutation among the nozzles, thereby reducing variability in droplet placement, and providing a more predictable spray from the nozzles. In other embodiments, the spray unit is utilized in a spray system adaptable to service vehicles, and may be utilized in conjunction with a vegetation engagement device, such as a cutter to engage multiple zones of a roadway right-of-way. Additionally, an improved spray unit includes an electromagnetic field and an attractor to generate plate motion.
