  • Patent number: 5062572
    Abstract: For use with agricultural sprayers, a unique spray shield is disclosed. The shields are mounted in pairs along the wet spray boom fore and aft in approximately the same plane, thereby shielding the nozzles of the sprayer. The shields are elongate and each is equipped with an air intake opening facing away from the wet spray boom. An air outlet of smaller cross-section is located at the bottom of each shield. As the sprayer moves in a direction against the wind, air enters the intakes of the fore shields and is directed downwardly and outwardly at a greater velocity thereby producing a curtain of air immediately in front of the sprayed area, thereby breaking the wind and avoiding disruption of the spray. Similarly, on the return passage over the land when the wind is blowing from the rear of the implement, the spray shields on the rear of the spray boom entrap the air and turn it downwardly, again creating a curtain of air behind the sprayed area.
