CHEMICAL SPRAY CONTROL DEVICE OF MOBILE PESTICIDE-APPLICATOR

摘要

PROBLEM TO BE SOLVED: To settle the problems that, conventionally, when a nozzle is worn out caused by long time use, excessive spray happens to cause crop injury and makes agrochemicals necessary the required amount.;SOLUTION: A mobile pesticide-applicator having a microcomputer pesticide-controller (20) for automatically changing spray amount linked with vehicle speed is provided, wherein an abnormality determining means (A) is provided which previously measures the flow rate through a spraying nozzle (11) at an arbitrary working rate and determining abnormality caused by an excessive flow rate when the flow rate of the current working rate exceeds the predetermined ratio based on the measured actual flow rate.;COPYRIGHT: (C)2009,JPO&INPIT
