Abstract:

A lawn chemical dispersal system including a remotely positionable spray nozzle having a nozzle intake connector and at least one nozzle discharge orifice; and a lawn chemical mixing unit having an intake hose coupling, a flow pipe in connection with the intake hose coupling; an anti-backflow valve installed within the flow pipe; a bottle connecting assembly including a bottle neck insertion cavity, a resilient bottle neck sealing ring, a mouth cover rupturing tube and a control valve, the control valve being in connection between the rupturing tube and the flow pipe; a lawn chemical bottle including a chemical bottle cover adhesively secured over and covering a chemical bottle opening and a chemical bottle neck, the chemical bottle neck sealing seating against the resilient bottle neck sealing ring when the chemical bottle neck is inserted into the bottle neck insertion cavity; a mixing assembly having an intake side and a discharge side, the mixing assembly further including an intake side screen and a discharge side screen defining a bead turbulence cavity therebetween, a supply of turbulence beads entrapped within the bead turbulence cavity, and a flow-driven bead agitator positioned within the turbulence cavity in a manner to agitate the quantity of beads when fluid flows through the bead turbulence cavity; and a discharge hose coupling in connection with the discharge side of mixing assembly, the discharge hose coupling being connectable to the nozzle intake connector in a manner to establish pressurized fluid flow therebetween.
