Claims (5)
- 持ち手部と、
作土層浮体板部と、
雑草抜脱部と、
からなる水田用除草具であって、
前記持ち手部と前記作土層浮体板部は、取り付け角度調整機構及び固定機構を介して、傾動及び固定可能に結合され、
前記作土層浮体板部は、水田における苗の株間又は条間方向を長手方向とする略長方平板形状の四隅に面取り及びアール加工が施され、持ち手部と雑草抜脱部とを合わせた重量及び浮力との関係で田面水に沈み作土層に浮く板状体であり、
前記雑草抜脱部は、抜脱用ワイヤーと、該抜脱用ワイヤーを前記作土層浮体板部の底面に張着状態で横架垂設するための二本の突出軸から構成され、
前記一組以上の雑草抜脱部が、前記作土層浮体板部の底面に具設されていることを特徴とする水田用除草具。 - 前記雑草抜脱部において、前記抜脱用ワイヤーの深さを調整可能にするために、前記突出軸の突出量を調整可能な深さ調整機構が設けられていることを特徴とする請求項1に記載の水田用除草具。
- 前記深さ調整機構が、
作土層浮体板部の上面部に設けるフランジと略キャップ形状の締付カラーから成り、
前記フランジは、前記突出軸を摺動可能に挿入するための貫通穴を有し、小径軸部の軸方向先端がテーパー状に形成され、周壁には軸方向にスリットを複数有し、外周面には雄ネジが形成され、
前記締付カラーは、内周壁に前記雄ネジと組み合わされる雌ネジと、前記フランジ小径軸部の軸方向先端に形設されたテーパー軸部と対応するテーパ軸受部が形設され、該締付カラーの回転により、前記小径軸部が螺合により前記突出軸の軸部を締め付ける構造であることを特徴とする請求項2に記載の水田用除草具。 - 前記雑草抜脱部に、前記抜脱用ワイヤーを前記突出軸からワンタッチで取り外せる抜脱用ワイヤー取外機構が設けられ、
該抜脱用ワイヤー取外機構が、
屈曲部と直線状保持部から成り、
前記屈曲部は、突出軸底部の抜脱用ワイヤー取付位置上部に、該突出軸を屈曲可能に軸支される分割構造を有して成り、
前記直線状保持部は、前記突出軸を軸方向に対して直線状態を保持するための固定用カラーから成ることを特徴とする請求項1から請求項3のいずれかに記載の水田用除草具。 - 前記作土層浮体板部に幅変更機構が設けられ、
該幅変更機構が、
前記作土層浮体板部において、長手方向に一以上分割される構成から成り、
該分割された各作土層浮体板部同士が摺動軸により、横方向に摺動することで前記作土層浮体板部の幅を変更可能にしたことを特徴とする請求項1から請求項3のいずれかに記載の水田用除草具。
