<p><P>PROBLEM TO BE SOLVED: To optimize a supply voltage depending on the kind of a nozzle part and to improve efficiency of spray operation in a spray working machine of electrostatic nozzle shape. <P>SOLUTION: In the chemical spray working machine equipped with a conductive part (50) in the vicinity of a spray nozzle (16) of a center boom (12) and in the vicinities of spray nozzles (18) of right and left side booms (13) and a high-voltage power source apparatus (51) for supplying a high voltage to the conductive part (50), the chemical spray working machine includes nozzle part determination means (R1 and R2) for determining nozzle parts (N1, N2 and N3) in a use state and optimizes a voltage supplied from the high-voltage power source apparatus (51) on the basis of the determination of the nozzle part determination means (R1 and R2). The nozzle determination means is a means for directly detecting positions of the rotating nozzle parts (N1, N2 and N3) or a means for estimation by setting of a spray amount. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
