The innovative RHEA airblast sprayer for tree crop treatment.

Authors present achievements in the research of appropriate solution about the RHEA sprayer for tree crops. The scenario of the most innovative technologies on airblast sprayer configuration has been analyzed and each solution on devices has been evaluated. UF unit has designed a semi-mounted sprayer applied to small autonomous tractor equipped with sensor able to recognize the presence, shape and thickness of the various horizontal bands of the canopy by adjusting the type of spraying. Spray application it is so variable separately on each band in term of direction of diffusors, airblast flow rate and liquid dose adequate to the presence or thickness of the canopy. The new RHEA airblast sprayer concept, in addition to the implementation of automated functions, has the aims to apply the rules specified by the European Union to reduce pollution caused by distribution of PPP (plant protection products).
