ABSTRACT:
This invention relates to a pneumatic soil penetrator and chemical applicator assembly operable, for example, to penetrate a soil surface and discharge a chemical toward the root system on a tree member or to broadcast the chemical about a large area. The pneumatic soil penetrator and chemical applicator assembly includes (1) a penetrator and applicator connected to a pneumatic supply to provide air pressure thereto; and (2) a chemical supply connected to the penetrator and applicator. The penetrator and applicator includes a main gun assembly having a primary inlet assembly; a main discharge assembly; and a control handle assembly in order to provide for selective control of fluid and chemical flow for (1) conveyance of the fluid flow and chemical therethrough; and (2) high pressure fluid flow to be used in a digging or penetration of the soil area. The primary inlet assembly includes a chemical inlet assembly having a venturi valve assembly utilized to pick up the chemical to be discharged therefrom from the chemical supply. The pneumatic soil penetrator and chemical applicator assembly is provided with an air deflector assembly operable to provide a seal with an upper surface of the soil area to direct the fluid flow downwardly for penetration purposes. The pneumatic soil penetrator and chemical applicator assembly includes a directional broadcaster assembly operable to be secured to an outer end of the main discharge assembly to direct the fluid and chemical flow downwardly for effective and efficient distribution thereof. The pneumatic soil penetrator and chemical applicator assembly is provided with an auxillary chemical supply assembly to provide for chemical discharge on a controlled limited amount.
