Claims (2)
- 可変周波数発生装置を有する高周波発生装置と、前記高周波発生装置に接続される単数又は複数の超音波発射器と、前記超音波発射器が三次元方向へ自在に振らせる回動装置と、を備えると共に、前記各超音波発射器を農圃の中又は端部の支柱上に設置した20KHz〜60KHzの超音波を発射する超音波防虫装置において、前記超音波発射器からの超音波が、40KHz〜60KHzの高い周波数帯と、20KHz〜40KHzの低い周波数帯の超音波を重畳しないで、かつ、それぞれを間欠的に、また、全体として途切れることなく発射することを特徴とする農圃における超音波防虫装置。
- 前記高周波発生装置を2組以上用い、前記高周波発生装置に位相変換装置を付加して、前記超音波発射器から発射する超音波の位相を調整することにより、2以上のほぼ同じ周波数の超音波を相互に干渉させて、強い音圧の超音波を発生させることを特徴とする請求項1に記載の農圃における超音波防虫装置。
