Abstract

A pressurizable tank for containing liquid fertilizer or the like is positioned transversely upon a two-wheeled carriage that can be pulled by a vehicle or by hand. The tank has a filler opening at one end. A container of pressurized gas is also attached to the frame adjacent to the tank. Suitable hoses and valves connect the pressurized container to the tank for charging the tank. Liquid flows from the tank through a hose to a spray nozzle that sprays it upon the ground. Interposed in the line from the tank is a quick-acting valve to control liquid flow. To facilitate safe filling of the fertilizer tank, the entire apparatus can be tipped on its side, resting upon the end of the fertilizer container opposite the filler opening. An auxiliary hand-operated nozzle system can be interchanged with the ground spray nozzle.

Claims

1. A chemical spraying apparatus comprising:

a carriage having a pair of laterally spaced wheels, a pressurizable chemical tank mounted transversely on said carriage, said chemical tank having first and second ends, said first end terminating in a substantially flat surface and said second end being provided with a chemical tank filler opening, said first end being so positioned on said carriage that a plane through said flat surface is substantially parallel to a plane through one of said wheels and is spaced laterally outwardly with respect thereto, a gas storage bottle for holding pressurized gas mounted on said carriage and being in communication with said chemical tank, first valve means for controling the flow of pressurized gas from said gas bottle to said chemical tank, chemical spray nozzle means, and second valve means for controling the flow of chemical from said chemical tank to said nozzle means.

2. The apparatus of claim 1 further comprising first pressure gauge means for indicating the pressure in said chemical tank and second pressure gauge means for indicating the pressure in said gas bottle.

3. The apparatus of claim 1 wherein said chemical tank is of elongated cylindrical shape.

4. The apparatus of claim 1 wherein said nozzle means is mounted on said carriage, and wherein chemical is supplied to said nozzle means by a nozzle supply line removably attached to said nozzle means.

5. The apparatus of claim 4 further comprising hand spray nozzle means attachable to said nozzle supply line.

6. The apparatus of claim 1 wherein said second valve means is of the quick operating cut-off type.

7. The apparatus of claim 1 further comprising hitch means attached to said carriage for attachment to a pulling vehicle, and auxiliary handle means attachable to said hitch means for allowing said carriage to be moved by hand.
