It is placed and fixed on the first transverse frame 16a and the second transverse frame 16b that are bridged in the direction of the direction.

  The propulsion device 4 is for advancing the boat body 3 along the traveling direction. As shown in FIG. 1 or FIG. 2, the propulsion propeller 9 and a power unit 11 for rotating the propulsion propeller 9 are used. And an arched duct 12 formed of a transparent resin, and a fuel tank 13.

  Specifically, the propulsion device 4 of this embodiment is orthogonal to the frames 15a and 15b on the rear side of the frames 15a and 15b provided on the boat body 3 and arranged in parallel and spaced apart in the traveling direction. It is placed and fixed on the third transverse frame 17a and the fourth transverse frame 17b that are bridged in the direction of the direction.

  The weeding device 6 is for weeding paddy fields and the like, and by dragging the chain 5 along the ground, weeds are pulled out or water and mud are agitated and the water becomes cloudy and inhibits photosynthesis. By doing so, weeds are withered, or mud is deposited on the weeds, thereby inhibiting the growth of the weeds, thereby producing a herbicidal action.

  As shown in FIG. 1 or 2, a plurality of chains 5 (six in this embodiment) are provided on a fifth transverse frame 18 that is bridged in the direction orthogonal to the frames 15a and 15b at the rear ends of the frames 15a and 15b. ) One end is fixed and suspended.

  A branched wire member 19 is fixed to the last part of the plurality of chains 5. In this embodiment, a linear member branched in four directions is fixed to each chain 5, so that a higher weeding effect can be obtained.

  The turning propeller device 8 is for changing the direction of the boat body 3 to the left and right. The weeding radio-controlled boat 1 of the present invention has such a turning propeller device 8 so that the rudder can be steered. There is no need to provide it, and it is configured as a radio control boat for weeding that has a simpler structure and better direction changing performance and operability.

  The turning propeller device 8 includes a pair of turning propellers 7a and 7b provided in the boat body 3 and arranged along the forward direction of the boat body 3, and a power device 14a for rotating the turning propellers 7a and 7b. 14b.

  As shown in FIG. 2 or 4, the turning propeller 7a is a right turning propeller arranged on the left side of the boat body 3 in a plan view and propelling the boat body 3 toward the right side. The rotation of the propeller 7a causes wind to be generated in the h direction (left direction) in FIG. 2, thereby causing the boat body 3 to rotate to the right.

  On the other hand, as shown in FIG. 2 or 5, the turning propeller 7b is a left turning propeller that is disposed on the right side of the boat body 3 in a plan view and propels the boat body 3 toward the left side. The rotation of the propeller 7b causes wind to be generated in the j direction (right direction) in FIG. 2 so that the boat body 3 turns leftward.

  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 direction change performance is higher. It is made up of a boat.

  The controller 10 is for controlling the turning propeller device 8 and the propulsion device 9 by wireless remote operation. The controller 2 receives a command by various operations of the controller 10 via a transmitter (not shown). It has a function to transmit to. As shown in FIG. 3, the controller 10 of this embodiment includes a left stick 20 that temporarily raises and lowers the hull speed and rotates the right turning propeller 7a to turn right, and a left turning propeller. By having the right stick 21 that rotates 7b and turns left, the boat body 3 can be moved freely in a paddy field or the like.

Next, a method for using the radio control boat 1 for weeding according to the present invention will be described together with a method for operating the controller 10.
When using the radio control boat 1 for weeding, first, the boat body 3 is floated on 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 moves forward while gradually accelerating. In the case of decelerating or stopping, the left stick 20 is configured to decelerate gradually when pressed down in FIG. 3 and to stop when it is further lowered. Further, when turning to the right, if the left stick 20 is tilted to the right in FIG. 3, the right turning propeller 7a turns to the right by rotating to blow in the direction h in FIG. On the other hand, when turning to the left, when the right stick 21 is tilted to the left in FIG. 3, the left turning propeller 7b rotates to blow in the direction j in FIG. ing.

  In this way, the radio-controlled boat 1 for weeding can freely move paddy fields and the like with an extremely simple operation, and even an elderly farmer can easily maneuver and turn the direction clockwise. Since it can be performed by the action of the propeller 7a for turning and the propeller 7b for turning left, it is not necessary to provide a rudder, and it is possible to produce the weeding radio controlled boat 1 having an extremely simple structure and superior in direction changing performance and operability.

  In addition, since the weeding device 6 is attached to the stern 3a side, the weeding device does not come into contact with crops such as rice and cause harm when the direction is changed, compared to the case where the weeding device is attached to the bow side. Furthermore, since the bow side becomes lighter, the turning by the right turning propeller 7a and the left turning propeller 7b becomes agile and stable.

  As the boat body 3 moves, the weeds 6 are dragged along the ground, so that weeds are pulled out, or water and mud are agitated and the water becomes cloudy and inhibits photosynthesis. As a result, weeds wither, and mud deposits on weeds inhibits the growth of weeds, resulting in herbicidal action. Furthermore, since the linear member 19 branched in four directions is fixed to the last part of the chain 5, a higher weeding effect can be obtained.

  The weeding radio control boat 1 of this embodiment has a pair of right turning propeller 7a and left turning propeller 7b at left and right symmetrical positions in FIG. 2, but is not limited thereto. Instead, it is also included in the scope of the present invention that the turning propeller device is composed of one turning propeller that can rotate forward and backward. This makes it possible to construct a radio control boat for weeding with a simpler structure. Further, a radio-controlled boat for weeding in which the boat body is equipped with a chemical solution spraying device including a chemical solution tank and a chemical solution spraying unit and is configured to be sprayed with a chemical solution by a controller is also included in the scope of the present invention. Thereby, the radio control boat for weeding which can perform both weeding work and chemical | medical agent spraying work simultaneously is comprised.
