Applicator

Claim 1

An applicator for applying chemicals to soil and the like comprising: a. a section of main tubular conduit having at its respective ends connection means for being connected into an irrigation line having a plurality of sprinklers connected with a source of pressurized water; b. a main container disposed adjacent said main tubular conduit; c. fill means for filling said main container with said chemicals to be applied to said soil; said fill means being disposed adjacent the top of said main container and communicating with the interior thereof; d. drain means for draining said main container; said drain means being disposed adjacent the bottom of said main container and communicating with the interior thereof; e. fluid inlet conduit disposed linearly of said main container adjacent the bottom thereof for conducting water into said main container; said fluid inlet conduit having spray means directed toward the bottom of said main container for maintaining said chemicals agitated in said water within said main container; said fluid inlet conduit extending into, sealingly penetrating through side walls of and communicating with the interior of said main tubular conduit for conducting water therefrom; f. effluent conduit sealingly connected with said main container for conducting fluid containing said chemicals therein into said main tubular conduit; said effluent conduit extending into, sealingly penetrating through side walls of, and communicating at its terminal end with the interior of said main tubular conduit for dispensing certain chemicals thereinto; g. admixing nozzle means connected with said terminal end of said effluent conduit within said main tubular conduit for effecting dilute, substantially uniform admixture of said chemicals at widely varying flow rates and widely varying pressures; said admixing nozzle means including an entry chamber having a plurality of apertures for dispensing said fluid containing said chemicals, and having a flaring skirt portion directed downstream and extending radially outwardly to within a distance of said side walls of said main tubular conduit sufficient to cause turbulence immediately downstream of said apertures in said admixing nozzle means and back pressure on said fluid inlet conduit adequate to effect substantially uniform admixture of said chemicals at said widely varying pressures and flow rates; whereby substantially uniform application of said chemicals is made on a field having even large elongate dimension.
