The turning propellers 7 (7a, 7b) are disposed along the forward direction of the boat body 3 (longitudinal direction of the boat body 3: direction of arrow K in FIG. 2) to generate wind forces directed respectively in the left and right direction. It is possible to make the left and right turn more agile, and further make the small turn in the U-turn and narrow seedlings more flexible.
　旋回用プロペラ７（７ａ，７ｂ）はボート本体３上に設けられるため、ボート本体３中に設ける（例えばスラスター内のプロペラ）より設置が極めて容易であると共に、旋回用プロペラ７（７ａ，７ｂ）の回転により発生する風力で旋回するため抵抗が小さくより機敏な旋回が可能となる。その結果、狭い苗間におけるＵターンやクイックターン等小回りが要求される水田などにおいて自在な旋回が可能になる。 Since the turning propeller 7 (7a, 7b) is provided on the boat body 3, it is extremely easy to install it (for example, a propeller in a thruster) provided in the boat body 3 and the turning propeller 7 (7a, 7b) Because it turns with the wind force generated by the rotation of the wheel, the resistance is smaller and a more agile turning is possible. As a result, it is possible to freely turn in a paddy field where a small turn such as a U-turn or a quick turn between narrow seedlings is required.
　旋回用プロペラ７ａは、図２または図４に示すように、平面視でボート本体３の左側に配されボート本体３を右側に向かって推進させるための右旋回用プロペラであり、右旋回用プロペラ７ａの回転によって、図２中、ｈ方向（左方向）に向かって風を生起させることにより、ボート本体３を右に旋回させるように作用する構成されている。 The turning propeller 7a is a right turning propeller disposed on the left side of the boat main body 3 in plan view for propelling the boat main body 3 to the right side as shown in FIG. 2 or FIG. By generating wind in the h direction (left direction) in FIG. 2 by the rotation of the propeller 7a, the boat body 3 is configured to turn to the right.
　他方、旋回用プロペラ７ｂは、図２または図５に示すように、平面視でボート本体３の右側に配されボート本体３を左側に向かって推進させるための左旋回用プロペラであり、左旋回用プロペラ７ｂの回転によって、図２中、ｊ方向（右方向）に向かって風を生起させることにより、ボート本体３を左に旋回させるように作用する構成されている。 On the other hand, as shown in FIG. 2 or 5, the turning propeller 7b is a left turning propeller disposed on the right side of the boat main body 3 in plan view for propelling the boat main body 3 toward the left side. By causing the wind in the j direction (right direction) in FIG. 2 by the rotation of the propeller 7b, the boat main body 3 is configured to turn left.
　また、これら右旋回用プロペラ７ａおよび左旋回用プロペラ７ｂは、図２に示すように、船首３ｂ側に設けられることで、船首３ｂが機敏に動作して方向転換性能がより高い除草用ラジオコントロールボートに構成されている。 Further, as shown in FIG. 2, the right turn propeller 7a and the left turn propeller 7b are provided on the bow 3b side, so that the bow 3b operates quickly and the weeding radio has a higher turning performance. Configured in a control boat.

　つぎに、本発明の除草用ラジオコントロールボート１の使用方法について、コントローラー１０による操縦方法と共に説明する。
　除草用ラジオコントロールボート１を使用する場合は、まず、ボート本体３を水田等に浮かべる。この状態で、コントローラー１０の左側スティック２０を図３中、上方に押し上げると、ボート本体３は徐々に加速しながら前進する。減速または停止させる場合は、左側スティック２０を図３中、下方に押し下げると徐々に減速し、さらに下げ続けると停止するよう構成されている。さらに、右に旋回させる場合は、左側スティック２０を図３中、右側に傾斜させると、右旋回用プロペラ７ａが図２中ｈ方向に送風するよう回転することで右に旋回する。他方、左に旋回させる場合は、右側スティック２１を図３中、左側に傾斜させると、左旋回用プロペラ７ｂが図２中ｊ方向に送風するよう回転することで、左に旋回するよう構成されている。 Next, a method of using the weeding radio control boat 1 of the present invention will be described together with a control method by the controller 10.
When using the weeding radio control boat 1, first, the boat body 3 is floated in a paddy field or the like. In this state, when the left stick 20 of the controller 10 is pushed upward in FIG. 3, the boat body 3 advances while gradually accelerating. When decelerating or stopping, the left stick 20 is configured to be gradually decelerated by pushing down the left stick 20 in FIG. 3 and to be stopped by continuing to be further lowered. Further, in the case of turning to the right, when the left stick 20 is inclined to the right in FIG. 3, the propeller 7a for turning right rotates so as to blow in the h direction in FIG. On the other hand, in the case of turning to the left, when the right stick 21 is inclined to the left in FIG. 3, the left turning propeller 7b is configured to turn to the left by rotating to blow in the j direction in FIG. ing.
　このように、除草用ラジオコントロールボート１は、極めて簡単な操作で水田等を自在に移動させることができ、高齢の農業従事者であっても容易に操縦することができると共に、方向転換をボート本体３上の船首側に設けられた右旋回用プロペラ７ａおよび左旋回用プロペラ７ｂの作用で行うことができるため、舵を設ける必要もなく、極めて簡素な構造で方向転換性能および操作性により優れている。 Thus, the weeding radio control boat 1 can freely move the paddy field etc. with extremely simple operation, and even elderly farmers can easily maneuver it, and also turn the direction change Since it can be performed by the action of the right turning propeller 7a and the left turning propeller 7b provided on the bow side of the main body 3, there is no need to provide a rudder, and the turning performance and operability with a very simple structure. Are better.
　また、除草器具６が船尾３ａ側に取り付けられているため、方向転換に際して、除草器具が船首側に取り付けられたものに比して、除草器具が稲等の作物に接触して害することもなく、さらに、船首側が軽くなるため、右旋回用プロペラ７ａおよび左旋回用プロペラ７ｂによる旋回も機敏で安定したものとなる。 In addition, since the weeding implement 6 is mounted on the stern 3a side, the weeding implement does not come into contact with crops such as rice and cause any harm as compared to those where the weeding implement is mounted on the prow side Furthermore, since the bow side is lightened, turning by the right turning propeller 7a and the left turning propeller 7b is also quick and stable.
　そして、このようなボート本体３の移動に伴い、除草器具６のチェーン５が地面に沿って引き摺られることによって、雑草が引き抜かれたり、水と泥が掻き混ぜられて水が濁って光合成を阻害することで雑草が枯れたり、雑草の上に泥が堆積することで雑草の成長が阻害されて除草作用が生じる。さらに、チェーン５の最後部には、四方に分岐した線条部材１９が固定されていることで、より高い除草効果を得ることができる。 Then, along with the movement of the boat main body 3, the weed 6 is dragged along the ground, so that weeds are pulled out, water and mud are stirred, and the water becomes turbid to inhibit photosynthesis. As a result, weeds wither and mud accumulates on weeds, thereby inhibiting the growth of weeds and producing herbicidal action. Furthermore, by fixing the striated members 19 branched in four directions to the rear end of the chain 5, a higher herbicidal effect can be obtained.
　なお、除草用ラジオコントロールボートのボート本体上に、薬液タンク、電動ポンプ、散布チューブ、コントローラーにて制御可能な散布チューブ開閉手段を備えた薬液散布装置を搭載したものも本発明の除草用ラジオコントロールボートの範疇に包含される。これにより、除草作業と薬剤散布作業の双方を行える除草用ラジオコントロールボートが構成される。 The weeding radio control of the present invention is also the one equipped with a chemical liquid dispersion apparatus equipped with a chemical liquid tank, an electric pump, a dispersion tube, and a dispersion tube opening / closing means controllable by a controller on the boat main body of the radio control boat for Included in the category of boats. This constitutes a weeding radio control boat that can carry out both the weeding work and the drug spreading work.
