This collection panel for an agricultural sprayer forms a hollow box comprising an air inlet opening and openings or pre-openings capable of receiving pulsed-air spraying assemblies.

An agricultural sprayer unit 700 and a spray deflecting mechanism 70 thereof for the sprayer unit 700 is provided. The agricultural sprayer unit 700 includes a control valve 702, a controller unit 703, a plurality of sprayer nozzles 704, a sprayer tank 706, a sprayer pump 708 and a spray deflecting mechanism 70. The spray deflecting mechanism 70 includes a spray defecting arrangement 72A and a collecting means 70T. The spray deflecting arrangement 70A is adapted to be moved between a deflecting position in which the spray deflecting arrangement 72A is adapted to deflect and re-direct unutilized dispensed fluid from at least one sprayer nozzle 704 to the collecting means 70T thereby restricting wastage of chemical agent/biological agent where the spraying is not required and also to restrict spraying of chemical agent/biological agent to healthy plants.

A boom for mounting to an agricultural sprayer comprises an elongate frame supporting a plurality of liquid application devices, liquid delivery means connected to the application devices, and an elongate tray attached to, and extending along, the boom. The tray is movable between a first position in which the tray extends substantially horizontally beneath one or more of the application devices to prevent material from leaking onto the ground below, and a second position in which the tray is located clear of delivery paths of the liquid application devices.

A spraying leg for an agricultural spraying machine, to an air-flow module for such a leg, and to an agricultural spraying machine provided with at least one such leg. Agricultural spraying machines which comprise spraying legs are known from the prior art, each spraying leg being provided with air diffuser and spray nozzle units, making it possible to send phytosanitary products driven by pulsed air onto the vegetation to be treated. A spraying nozzle is provided which can easily be adapted to the nature of the plants to be treated, in particular to the height and the configuration thereof. The spraying nozzle comprises at least one mounting, and a plurality of spraying modules attached to the mounting, each module forming an air-flow duct capable of each supporting at least one air diffuser and spray nozzle unit, the modules being connected to one another.

A mobile agricultural spray apparatus, the spray apparatus including at least one spray nozzle arranged to be on one side of a crop during spraying and an overspray collector arranged to be on the opposite side of the crop during spraying such that the overspray collector can capture overspray from the spray nozzle during operation, wherein the overspray collector includes: at least two curtains, the curtains including at least one pervious and flexible front curtain and an impervious rear curtain; an overspray space between the pervious front curtain and the impervious rear curtain; and an overspray chamber in fluid communication with at least the overspray space for collection of overspray captured by the overspray collector.

A boom for mounting to an agricultural sprayer which includes an elongate frame that supports a plurality of liquid application and delivery means, and an elongate tray attached to, and extending along, the boom. The tray is movable between a first position in which the tray extends substantially horizontally beneath one or more of the application devices to prevent liquids from leaking onto the ground below, and a second position in which the tray is located clear of delivery paths of the liquid application devices.
