ABSTRACT:
An apparatus is provided for mixing granular fertilizer and/or a liquid insecticide or other treatment liquid in water in an upstanding tank having an opening for its water supply which is piped to the tank above a porous strainer to an area in the upstanding tank below the porous strainer and to a pipe whose function is to provide a pressurized flow of water to the tank for cleaning purposes. The bottom of the tank has an outlet for dispensing the mixture into an irrigation piping system or a sprayer attachment. The apparatus has a motor-driven vertical shaft with upper and lower blades inside the tank. A screen with a funnel-shaped wide upper end and a smaller cylindrical lower end extends around the shaft from a location near the upper end of the tank down to a point perpendicular to the horizontal plane of the bottom of the inner tank. A porous strainer extends across the top of the tank above the wide funnel mouth of the screen. A hopper at the top of the tank passes granular fertilizer down onto this strainer and all except oversized particles pass down through this strainer into the tank at the constriction of the screens. A reservoir for the insecticide or other lawn treatment liquids extends from the top of the tank down to a manual valve which extends down through the strainer for passing the liquid down into the tank at the inside of the screen. A spray pipe extends around and through the funnel-shaped end of the screen for spray-cleaning the screen, when needed.
