Abstract
Abstract A rotary atomizer suitable for spraying crops with liquid is driven by the liquid itself. The atomizer comprises a hollow, truncated cone, a central axial shaft extending through the interior of the cone, a liquid jet driven turbine on the shaft, and an opening in the turbine so that liquid flows from the turbine to the interior of the cone. The liquid may be used at pressure of 0.7 to 10 bars gauge and feed rates of 10 to 1,000 ml/min, with the rate of feed being equal to the rate of discharge so that there is no liquid recycle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
65 words
A rotary atomiser comprising a hollow truncated cone characterized in that it has a central axial shaft extending from the base of the cone through the interior of the cone, and a liquid jet driven turbine on the axial shaft, the turbine having an opening on the side nearest the cone so that liquid can flow from the turbine into the interior of the cone.
Claim 2
Dependent Claim
65 words
A rotary atomiser comprising a hollow truncated cone characterized in that it has a central axial shaft extending from the base of the cone through the interior of the cone, and a liquid jet driven turbine on the axial shaft, the turbine having an opening on the side nearest the cone so that liquid can flow from the turbine into the interior of the cone.
Claim 3
Dependent Claim
20 words
A rotary atomiser as claimed in claim 1 characterized in that the liquid jet driven turbine is a Pelton wheel.
Claim 4
Dependent Claim
22 words
A rotary atomiser as claimed in claim 1 characterized in that the liquid jet driven turbine has from 1 to 6 jets.
Claim 5
Dependent Claim
38 words
A rotary atomiser as claimed in claim 1 characterized in that a non-rotating guard is placed between the turbine and the interior surface of the cone to direct liquid from the turbine to the base of the cone.
Claim 6
Dependent Claim
25 words
A rotary atomiser as claimed in claim 1 characterized in that the liquid system to supply the jet of the turbine contains a three-way valve.
Claim 7
Dependent Claim
37 words
A method of spraying using a rotary atomiser as claimed in claim 1 characterized in that liquid is fed to the jet and discharged from the cone in substantially equal amounts, there being no recycle of liquid.
Claim 8
Dependent Claim
33 words
A method of spraying as claimed in claim 6 characterized in that the liquid pressure is from 0.7 to 10 bars gauge, and the liquid feed rate is from 10 to 1,000 ml/min.
