ABSTRACT:
A field spraying device comprises an elongated spray beam provided with a plurality of spray nozzles (12). The field spraying device comprises an at least partially inflatable hose (18) connectable to a compressed-air source. The hose comprises a slotted discharge opening (13) extending in the longitudinal direction of the hose. The spray nozzles (12) spray the liquid into the air flow approximately 200-300 mm below the slotted opening which results in a uniform discharge of material. In this manner the spray beam can be situated close to the ground and the crop, respectively, with the effect that a possible wind movement is reduced. The slotted discharge opening (13) is pivotally mounted by utilizing the fact that the at least partially secured hose (18)is made of a resilient material. In other words the invention utilizes the feature that the resilient top portion allows a turning movement in such a manner that the discharge opening can be adjusted. As a result it is possible to take the velocity of the wind, the velocity of the vehicle etc. into account. Furthermore it is possible to improve the utilization of the sprayed materials and to take optimum care of the crop.
