Liquid herbicide attachment for granular applicator
First Claim
1. For use in combination with an air conveying system for conveying particulate materials through conduits for distribution onto the surface of the ground, the improvement comprising a liquid pesticide injector attachment, said pesticide injector attachment including means for providing a metered amount of pesticide, and means for injecting the metered amount of pesticide in a flowable, nonatomized liquid form as it is introduced into a conduit carrying air entrained particulate material past the means for injecting, to thereby have the liquid pesticide material carried by the particles and air stream to the outlet of the conduit.

Abstract
A liquid pesticide attachment for a granular material applicator for agricultural use which provides for injecting a metered amount of the liquid pesticide into an air stream containing a metered amount of granular material to be distributed, and having the material travel together to be deposited onto the ground. With any air distribution system for inorganic particulate material, a mixture of air and the particulate material is carried in a conduit, and a metering device is attached to provide for adding of the liquid material into the air-particulate material as it is being conveyed.

9. for use in a particular material spreader mounted onto a vehicle and movable over the surface of the ground for spreading particulate material, said spreader comprising a plurality of boom tubes, and means for providing particulate material entrained in an air stream and conveyed through each of the boom tubes from an inlet end to an outlet end, said boom tubes being mounted into a boom assembly the improvement comprising an injector for injecting liquid pesticide into the air entrained particulate material stream in each of the conduits and including a plurality of metering pumps, one for each of the boom tubes mounted on said vehicle;
-
means for driving said metering pumps to provide a metered amount of liquid pesticide at an outlet of the pump; a separate flow tube connected to the outlet of each pump; and a separate connector member mounted on each of said boom tubes on a lateral side thereof said connector members having passageways therethrough forming orifices positioned on the interior of the conduits, each of the separate flow tubes connecting the outlet of a separate pump to one of the boom tubes to convey a metered amount of the liquid pesticide into the interior of the respective boom tubes for injection into the air entrained particulate material being carried in that conduit.

- 10. A liquid pesticide injector attachment for an air conveying system which conveys particles of material to a plurality of individual conduits, each having an inlet and an outlet end, and wherein the particles of material are discharged at the outlet end for distribution under the surface of the ground, said pesticide injector attachment including means for metering a selected amount of liquid pesticide into a plurality of liquid carrying lines, an orifice fitting in each conduit between the inlets and outlets thereof, each orifice fitting being connected to receive liquid pesticide from one of the liquid carrying lines, the metered amount of pesticide being introduced into the conduit as a flowing, nonatomized liquid to contact the particles conveyed past the orifice fitting to thereby have the liquid pesticide material coat the particles as the particles are carried in the conduit to the outlet end of the conduit for discharge.
