ADJUSTABLE OVER-THE-TOP AGITATOR FOR A LIQUID MANURE TANK

摘要

An adjustable over-the-top agitator for a liquid manure tank. To periodically break up the crust on liquid manure stored in an open top tank, the liquid manure is withdrawn from the bottom of the tank and is discharged through a nozzle on the end of an external delivery pipe into contact with the crust. The upper end of the delivery pipe is connected by a swivel coupling to a vertical end of a connecting pipe, while the opposite horizontal end of the connecting pipe is connected by a second swivel coupling to the discharge nozzle. By rotating the connecting pipe about the axis of the delivery pipe, the nozzle can be moved in a horizontal path, while swiveling the discharge nozzle about the horizontal end of the connecting pipe moves the nozzle in a vertical arc. A torsion spring is associated with the second swivel coupling to bias the discharge nozzle to a horizontal position. Through use of the horizontal and vertical adjustments, the nozzle can be directed to all locations in the tank to more effectively break up the crust on the top of the liquid manure mass.
