Title : The influence of nozzle configuration in orchard sprayers on the vertical distribution of spray
Key words : orchard sprayer, vertical spray distribution, vertical spray separator, spray share, patternator
Summary :

The aim of the study was to determine the effect of the selected operating parameters of the two types of orchard sprayers on vertical distribution (expressed as spray percentage share in 50-cm segments) and quantitative changes in vertical distribution of spray measured on a vertical separator of drops. The study included measurements of vertical distribution of spray for two different settings of nozzles, two types of nozzles and two fan rotational speeds. Vertical distribution of spray depended significantly on the spray emission system, the configuration and the type of nozzles and in the slightest degree on the fan rotational speed. The smallest share of liquid fell on the edge segments (≤ 5.22%) and the largest on the middle ones – 29.33%. The change in the configuration of nozzles significantly affected the change in the spray vertical distribution (by the spray displacement between the 50-cm segments). The greatest changes in vertical distribution of spray – as affected by the nozzle configuration change – was observed for the sprayer with the horizontal spray emission with a maximum change in one segment of 14.0% (an average of 7 segments: 5.38%).
