ABSTRACT:
A wettable spray box for dispensing wettable agricultural spray powders in a tank of spray equipment so as to protect the operator from exposure to the powders is disclosed. The spray box comprises a box (10) with a lid (12) for attachment to the spray tank. The bottom of the box is fitted with a main pipe (18) which extends into the spray tank. A fill pipe (24) extends part way down the interior of the main pipe (18) and is connected to a source of water. One or more knives (34) within the box (10) are positioned to slit a bag of wettable powder which is inserted into the box. A water injector (40) extends into the slit bag, and a spray head (48) is positioned near the top of the box. An inserted bag is prevented from falling to the bottom of the box (10) by a rack or screen (28). In use, an unopened bag of wettable spray material is inserted into the box (10) and the lid (12) is closed to seal the box. The knife (34) slits open the bag, and water is supplied to both the injector (40) and the spray head (48) to expel the powder from the bag and clean the interior of the box. Additional water is added to the mixture by means of the fill pipe (24) which enhances the flow of chemicals into the spray tank and further mixes the powder in the water.
