  Reference numeral 6 denotes a stopper for connecting the mounting portion 3 of the thrust transmission body 2 and the helicopter mounting portion 5, and is provided on the opposite side of the flexible connecting portion 5, that is, on the front side of the base 1. The stopper 6 is capable of bending the upper plate 7 and the lower plate 8, a two-blade type first hinge 9 connecting the upper plate 7 and the lower plate 8, and the lower plate 8 to the mounting portion 3 in a substantially square shape. And a two-blade type third hinge 11 that connects the upper plate 7 to the helicopter mounting portion 5 so as to be bent in a substantially square shape. It can be bent in a substantially square shape.

Here, the connection between the upper plate 7 and the helicopter mounting portion 5 will be described in detail with reference to FIGS. 2 and 3. FIG. 2 is a diagram before connection, and FIG. 3 is a diagram after connection. A stopper side hole 11 </ b> A for inserting the connection pin 12 is formed in the approximate center of the upper wing 11 </ b> A constituting the third hinge 11.

  Since the stopper 6 is configured to be upright and bendable using the first hinge 9, the second hinge 10, and the third hinge 11 as described above, the stopper 6 is inclined when the helicopter mounting portion 5 is directed upward, that is, tilted backward. 6 becomes an upright state, and the helicopter mounting part 5 is prevented from further tilting backward. Further, when the mounting portion 5 is directed downward, that is, when tilted forward, the stopper 6 is bent in a substantially square shape so that the downward movement of the mounting portion 5 is not hindered.

  Reference numeral 13 denotes a stopper holder formed in an inverted L-shaped plate. The stopper holding body 13 is provided on the mounting portion 3 so that the tip 13A comes into contact with the stopper 6 which has been brought into an upright state in conjunction with the mounting portion 5 being directed upward. The front end 13A abuts against the stopper 6 to stop it, thereby preventing the stopper 6 from bending inward (in the direction of the stopper holder 13). In addition, since the stopper holding body 13 is for preventing the stopper 6 from bending inward, it is not limited to an inverted L shape, and may be, for example, a columnar shape.

  Reference numeral 14 denotes a radio control helicopter (hereinafter abbreviated as helicopter 14) that can be remotely operated by a remote controller (not shown). The helicopter 14 includes a main body 14A, a tail body 14B extending rearward of the main body 14A, a main rotor 14C provided on the upper portion of the main body 14A, a tail rotor 14D provided on the rear portion of the tail body 14B, and a lower portion of the main body 14A. And supporting legs 14E provided on the base plate. The main body 14A is provided with an engine for rotating and driving the main rotor 14C and the tail rotor 14D, a radio control receiver, a servo motor, and the like (not shown).

  The helicopter 14 rotates the main rotor 14C and the tail rotor 14D by the power of the engine, generates lift and thrust by the main rotor 14C, suppresses the reaction torque of the main rotor 14C by the tail rotor 14D, and the nose of the helicopter 14 It is configured to change the direction of the, and there is no difference from the conventional radio-controlled helicopter. Accordingly, the helicopter 14 moves forward by tilting the aircraft forward, moves backward by tilting backward, and turns left and right by tilting left and right. In this way, the basic operation and control method are the same as those of a general radio control helicopter.

  The helicopter 14 is placed on the placing portion 5 with the front side facing the stopper 6, and two rod-like fasteners (not shown) are provided on the left and right support legs 14 E, and Bolts are inserted into both end sides and the helicopter fixing holes 5C and fixed by tightening nuts.

  Reference numeral 15 denotes a storage tank provided on the substrate 1, and liquid agricultural chemicals are stored in the storage tank 15, for example.

Reference numeral 17 denotes a spray nozzle provided in the spraying device 16 for spraying agricultural chemicals. The spraying device 16 is composed of a motor and a fan, and can be remotely operated by a remote controller (not shown). The remote controller for operating the spraying device 16 may be integrated with the remote controller for remote operation of the helicopter 14, or another one may be used.

  Although the present embodiment has the above-described configuration, its operation and usage will be described with reference to FIGS. First, the helicopter 14 is placed on the placement unit 5 as described above, and the radio-controlled moving body is floated on the paddy field in a fixed state. Then, the remote controller performs the same operation as when the helicopter 14 flies in the air. That is, by rotating the main rotor 14C and the tail rotor 14D and changing the propeller pitch, the helicopter 14 obtains thrust for forward, reverse, left turn, and right turn. The helicopter 14 is fixed to the mounting portion 5 so that the base body 1 is suspended, so that the helicopter 14 does not rise greatly depending on the manner of operation.

  Then, when the radio controlled moving body is moved forward, the helicopter 14 is tilted forward in the same manner as a normal helicopter operation. Since the mounting portion 5 is connected to the mounting portion 3 via a flexible connecting portion 4 configured to bend in the vertical and horizontal directions, the helicopter 14 is tilted forward as shown in FIG. When the flexible connecting portion 4 is bent, the placement portion 5 is also tilted forward. In this state, the thrust of the helicopter 14 is transmitted to the base body 1 through the thrust transmission body 2, and the wireless steering moving body moves forward.

  On the other hand, when the radio-controlled moving body is moved backward, the helicopter 14 is tilted rearward in the same manner as a normal helicopter operation. Then, as shown in FIG. 4, the flexible connecting portion 4 is bent, the front portion is lifted, the mounting portion 5 is tilted rearward, and the thrust of the helicopter 14 is transmitted to the base body 1 through the thrust transmission body 2, and wirelessly. The maneuvering body moves backward.

  In addition, if the operation is mistaken when the helicopter 14 is tilted backward in an attempt to move the radio-controlled moving body backward, there is a possibility that the mounting portion 5 is excessively tilted. However, as shown in FIG. 5, the stopper 6 connecting the mounting portion 3 and the placement portion 5 is brought into an upright state to prevent the placement portion 5 from being inclined further. It is reliably prevented that the part 5 is tilted excessively and the radio control moving body is turned over.

Also, when turning the radio controlled moving body forward or backward, turn right or turn left,
It is the same as a general radio control helicopter in that it is performed by controlling the rotation speed and pitch angle of the main rotor and tail rotor.

  In this case, the stopper 6 is pivotally connected to the protrusion 5D of the mounting portion 5 by the connection pin 12, and the connection pin 12 serves as a fulcrum when the mounting portion 5 is tilted in the left-right direction as shown in FIG. It is like that. That is, since the mounting portion 5 tilts to the left and right without the shaft being shaken with the connection pin 12 as a fulcrum, the wireless steering moving body can turn left and right in a stable state.

  When turning left and right while the radio controlled moving body stays in place, it is the same as turning left and right while the helicopter is hovering. The angle of attack of the tail rotor 14D is decreased to reduce the thrust, and when turning left, the angle of attack of the tail rotor 14D is increased to increase the thrust. By operating in this way, the thrust of the helicopter 14 is transmitted to the base 1 via the thrust transmission body 2, and the radio-controlled moving body does not need to consider the turning radius and turns left and right while staying on the spot. Can do.

  As described above, the helicopter 14 is remotely operated to slide the radio controlled moving body, and the spraying device 16 is remotely operated with the remote controller to spray the spraying material such as agricultural chemicals from the spray nozzle 17. In this case, since spraying is performed in the state of being close to the water surface or the ground, unlike spraying from the air with a helicopter, the sprayed material can be reliably sprayed to the desired place, and the sprayed material is scattered in the air and is wasted. Never become.

  As described above, according to the present embodiment, the helicopter 14 is mounted and fixed on the mounting portion 5, and the radio-controlled moving body can move forward, backward, and turn left and right with the thrust of the helicopter 14. The radio-controlled mobile body can be run with the same operational feeling as the helicopter 14. Therefore, a person who can operate the helicopter 14 can easily operate the radio-controlled moving body without having to learn and learn a new operation method.

  In the field of agriculture, spraying agricultural chemicals and the like from the air using a radio-controlled helicopter has been conventionally performed, so if you are a person who controls a radio-controlled helicopter and sprays agricultural chemicals, this embodiment It is possible to easily perform spraying operations such as spraying agricultural chemicals on paddy fields or spraying a snow melting agent on the snow surface using the radio controlled moving body according to the above.

  Further, conventionally, even if the helicopter 14 is owned for spraying agricultural chemicals from the air, it is necessary to prepare another hovercraft for spraying agricultural chemicals and the like from near the water surface. However, according to the present embodiment, it is possible to carry out spraying from the air and spraying from the surface of the water or near the ground by using a helicopter 14 on hand, and it is not necessary to prepare a hovercraft, and equipment costs can be reduced. .

  Further, since the operation method and operation feeling are different between the helicopter 14 and the hovercraft, even a person who can operate the helicopter 14 needs to learn a new operation method when using the hovercraft. However, according to the present embodiment, if the helicopter 14 can be operated, the water surface can be slid like the hovercraft without having to learn a new operation method. You can avoid wasting time.

  In this embodiment, the case where the water surface such as a paddy field is slid is described. However, the present invention is not limited to the water surface, and various places where it is difficult or impossible for a person such as a wetland, a swamp, a frozen lake surface, a snowy field, etc. Can be used.

  Moreover, although this Embodiment demonstrated the case where it uses for agricultural chemical dispersion | distribution in agricultural work, the radio control moving body which concerns on this invention is not restricted to an agricultural chemical dispersion | distribution, It can be used also for other work, such as conveyance work. Furthermore, it can be used not only for various operations but also as a play equipment that slides on the surface of water. In this way, if the helicopter 14 is owned, it is possible to enjoy water surface skiing different from flying in the air using the owned helicopter 14 without purchasing a hovercraft or the like which is a play equipment for gliding such as the water surface.

It is an external appearance perspective view which provided the thrust transmission body, the storage tank, and the spreading | diffusion apparatus in the base | substrate which concerns on one embodiment of this invention. It is an external appearance perspective view of the thrust transmission body which shows the state before the connection of a stopper.
