Inductively charged spraying apparatus

摘要

A spraying apparatus to deliver inductively charged spray, for example to crops. The apparatus includes a spray head and electrodes to apply a potential difference in the region of the spray head to charge spray. An aspirating means is arranged to remove liquid deposited on an electrode to reduce interference with the charging process. When the spray liquid is to be at high potential in the apparatus a long high resistivity supply tube may be provided. The aspirating means may be operated by spray liquid bled from a pressurized supply spray liquid.
