On the Character of the Blower Type Pest Control Machine (IV)

Trial making of Cyclone for Duster

Abstract

On the dusting method of Duster, it is necessary that the times of dust discharge must be uniform for protect from injury of plant by agricultural chemicals and the effect of Pest control for plant are uniformed.
In this view, we made a Cyclone for trial to measure the variations of dust discharging times continuously, by applying the Stoke's low of Fluid dynamics.
As the result, we could measure the variations of dust discharging time about some Knapsack type engine duster, on high Withdrawal efficiency of dust (=85%) continuously.
Wherefore, we are thought that must be study the mechanism of dust disharge, because many dusters have characters of un-uniformed dust discharge almost.
