PROBLEM TO BE SOLVED: To uniformly spray a chemical fluid to leaves and stems of crops in an electrostatic spray apparatus.SOLUTION: The electrostatic spray apparatus of a farm work vehicle includes rod-like front and rear high-voltage conductors 61 and 61 along the right and left directions disposed under spray nozzles 3 installed at a nearly prescribed interval in a spray boom 4 to apply a high voltage to the front and rear high-voltage conductors 61 and 61. Only the front and rear high-voltage conductors 61 and 61 located under the spray nozzles 3 of the spray boom 4 comprise circular ring parts 61a which become mutually more distant in the front, rear, right and left from the spray nozzles 3 when viewed from the plane, and comprise the circular ring parts 61a adjacent to right and left so as to connect in linear parts along the right and left directions.COPYRIGHT: (C)2010,JPO&INPIT【課題】静電散布装置において作物の茎葉部に薬液を均等散布する。【解決手段】散布ブーム4に略所定間隔毎に設けている噴霧ノズル3,…の下方に、左右方向に沿った棒状の前後高電圧電導体61,61を配設し、該前後高電圧電導体61,61に高電圧を印加するように構成し、前記散布ブーム4の噴霧ノズル3,…の下方に位置する前後高電圧電導体61,61のみを、平面視で前記噴霧ノズル3,…から互いに前後左右に遠ざかる円環部61a,…に構成し、左右に隣接する円環部61a,…を左右方向に沿った直線状部で接続するように構成したことを特徴とする農作業車の静電散布装置の構成とする。【選択図】図5
