<P>PROBLEM TO BE SOLVED: To solve a problem that a conventional spray nozzle is composed of an umbrella-shaped recessed part provided in a nozzle body and a cylinder nozzle provided on the bottom of the recessed part to have a structure for spraying a chemical agent or water, and though a conical spray shape is secured with a range of up and down 45° and the spray nozzle can spray them to crops in a house, a cylinder nozzle can not spray them to every corner of the crops due to occurrence of a state that the chemical agent in a central part is not static-charged, that is, efficient spraying is impossible to cause adverse influence. <P>SOLUTION: The electrode structure of the spray nozzle includes: a supporting cylinder provided in a spray nozzle tiltably on a supporting rod 22 of a monorail; and an electrode part supported with a certain interval from the supporting cylinder includes a body, a slit-shaped spray port opened in the body, electrode plates provided on the opposed surfaces of the spray port in the longitudinal direction and a terminal part 10 for a cord for supplying electricity to the electrode plate. <P>COPYRIGHT: (C)2011,JPO&INPIT |
