Definitions

  • This invention relates generally to lawn treatment systems for alternatively applying either a water diluted fertilizer, or a mixture of the water diluted fertilizer and a liquid pest control product, e.g., an insecticide or pesticide.
  • a water diluted fertilizer or a mixture of the water diluted fertilizer and a liquid pest control product, e.g., an insecticide or pesticide.
  • the objective of the present invention is to address this shortcoming of the prior art, in addition to providing other important advantages.
  • a system in accordance with the present invention comprises a tank containing a supply of a liquid pest control product, hereinafter referred to as the “first liquid”.
  • a positive displacement pump operates to withdraw the first liquid from the tank via a suction conduit, and to deliver a pressurized flow of the first liquid via a delivery conduit.
  • a metering orifice in the delivery conduit is adjustable to control the flow of the first liquid.
  • a first valve is located in the delivery conduit between the pump and the metering orifice.
  • the first valve is normally closed, is opened in response to a pressure of the first liquid exceeding a threshold level, and when open, is operative to deliver the first liquid to the metering orifice at a substantially constant pressure.
  • a bypass conduit communicates with the tank and the delivery conduit at a location between the first valve and the pump.
  • a flow restrictor moderates flow in the bypass conduit.
  • the flow restrictor may comprise a second valve that is adjustable to accommodate a controlled return flow of the first liquid from the delivery conduit to the tank, thereby modulating the pressure of the first liquid being delivered to the first valve.
  • the flow restrictor may comprise a second metering orifice sized to accommodate set return flow of the first liquid.
  • a pressure gauge is provided for visually displaying the pressure of the first liquid being delivered to the first valve, and the metering orifice also includes a visual display of the volume of the first liquid flowing through the delivery conduit.
  • the system further comprises at least one delivery hose having first and second hose conduits leading to a handgun.
  • the delivery conduit is connected to the first hose conduit, and the second hose conduit is connected to a pressurized source of a water diluted fertilizer, hereinafter referred to as a “second liquid”.
  • the handgun is adapted to alternatively deliver only the second liquid, or a mixture of the first and second liquids.
  • the drawing is a diagrammatic illustration of a system embodying the concepts of the present invention.
  • the first liquid will comprise water diluted insecticide or fungicide and the second liquid will comprise a water diluted fertilizer.
  • a first tank 10 is adapted to contain a supply of the first liquid.
  • a positive displacement pump 12 is operable to withdraw the first liquid from the tank 10 via a suction line 14 and to deliver a pressurized flow of the first liquid to a metering orifice 16 in a delivery conduit 18 .
  • the metering orifice is adjustable to control liquid flow, and includes a gauge for visibly displaying flow volume.
  • a first valve 20 is located in the delivery conduit 18 .
  • the first valve is of the constant flow type, examples of which are disclosed in U.S. Pat. Nos. 6,026,850; 6,208,578; 7,445,021 and 7,363,938, the descriptions of which are herein incorporated by reference.
  • Valve 20 is normally closed, is opened in response to liquid pressure exceeding a threshold level, and is operative when open to deliver liquid to the metering orifice as a substantially constant pressure.
  • the volume of flow passing therethrough will remain substantially constant, thereby avoiding inadequate or excessive application of the water diluted chemical concentrate.
  • a bypass conduit 22 communicates with tank 10 and with the delivery conduit at a location between the pump 12 and the first valve 20 .
  • a flow restrictor 24 moderates flow in the bypass conduit.
  • the flow restrictor may comprise a second valve that is adjustable to accommodate a controlled return flow of the first liquid from the delivery conduit 18 to the tank 10 .
  • the flow restrictor may comprise a metering orifice sized to accommodate a set flow of the first liquid. This return flow constantly agitates the tank contents while guarding against over pressurization of components downstream of the pump 12 .
  • the system further comprises at least one delivery hose 26 leading to a portable handgun 28 .
  • the delivery hose is of a known type which includes first and second hose conduits 26 a , 26 b .
  • the delivery hose is stored on a reel 30 , with the first hose conduit 26 a connected to the delivery conduit 18 , and the second hose conduit 26 b connected to a pressurized source 32 of the second liquid.
  • the handgun 28 is adapted to alternatively deliver only the second liquid, or a mixture of the first and second liquids.
  • a second hose reel 30 ′, handgun 28 ′ and pressurized source 32 ′ of a different second liquid are included.
  • a check valve 34 prevents back flow in the delivery conduit 18 .
