Abstract
Official abstract text for this publication.
The application is generally directed towards a drop nozzle for an agricultural sprayer. The drop nozzle can be used to reduce spray drift as liquids are deposited by the sprayer. The drop nozzle includes a valve assembly including a shutoff valve, a tube operably connected to the valve assembly, and an airfoil connected to the tube. The shutoff valve selectively prevents fluid flow from the valve assembly to the tube and the airfoil directs airflow around one or more portions of the drop nozzle.
First claim
Opening claim text (preview).
What is claimed is: 1. A drop nozzle for an agricultural sprayer, comprising: a valve assembly comprising a shutoff valve; a tube operably connected to the valve assembly; a spray tip in fluid communication with the tube for spraying fluid; and an airfoil connected to the tube, the airfoil comprising an air guide angled downward from an end of the airfoil towards the spray tip, wherein as the drop nozzle is moved by the agricultural sprayer, air travels over a top outer sur…
