Description

  The present invention relates to, for example, a bee controlling apparatus for nesting at a high altitude, and particularly to a technical field of controlling a bee using an unmanned aerial vehicle and a medicine.

  In recent years, the red-horned wasp native to China has been discovered in Japan as an exotic organism. It is pointed out that hornet wasps are ferocious and have high fertility, as well as preferentially attack honeybees of Japanese native species. Immediate eradication is required. There is a strong demand to eliminate bees that could harm other bees other than the hornet.

  As a method for controlling bees, for example, methods disclosed in Patent Documents 1 and 2 are known. In Patent Literature 1, a bee's attacking vibration sound is generated to attract a bee, the bee swarms around the bee is killed by injecting hot water into the beehive, and then hot water is poured into the beehive. They try to get rid of the bees in the nest. It is disclosed to use a support pole when there is a nest at a high place. Further, in Patent Document 2, a tip pole is connected to a tip end of a telescopic main pole by a hinge, an insecticide spray can is attached to the tip pole, and a spray button of the insecticide spray can is pressed by remote control to kill the insect. The agent is sprayed.

Japanese Patent No. 5586802 Japanese Utility Model Registration No. 3188587

  By the way, in Patent Documents 1 and 2, a nest at a high place and a bee around it are controlled by using a supporting rod or a pole, but such a supporting rod or a pole is held by an operator with his / her own hand. Since it is necessary to operate the robot in a state where it is supported, it is assumed that the common-sense length of the support pole or the pole is at most about 5 m to 6 m. The above-mentioned hornet wasp has a habit of forming a nest at a high place of a tree. Specifically, the hornet may form a nest at a height of 8 m to 10 m or more from the ground. It is difficult or impractical to control the hornet by the method of I. Therefore, for example, it is conceivable to carry out an extermination operation using an aerial work vehicle, but there is a problem in terms of safety when an aerial work vehicle is used.

  The hornet also sometimes builds a beehive in a place where aerial work vehicles cannot enter (for example, in a remote mountain). Considering the damage to honeybees, we want to exterminate even such places promptly, but there is also a problem that work using an aerial work vehicle cannot be performed in such places in the first place.

  Bees, including hornets, can also nest in densely populated branches like trees in natural forests. In such a case, even if a support rod or a pole as disclosed in Patent Literatures 1 and 2 is used, the branch does not allow the tip of the support rod or the pole to reach the nest, and work at high places Even if a car is used, it cannot be reached unless the branches are cut off, and bees cannot be eliminated quickly.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to enable safe and prompt extermination of bees that form nests at relatively high places.

  In order to achieve the above object, in the present invention, an unmanned aerial vehicle is used to supply a drug to a beehive.

The first invention is
A multicopter having an airframe and a plurality of rotors arranged at intervals from each other;
An aerosol container that is provided on the body and contains a drug for exterminating bees inside,
A tubular member provided on the body and constituting a passage through which the medicine ejected from the aerosol container flows,
At the tip of the tubular member, an injection attachment for injecting a drug into the honeycomb, at the tip of the tubular member, at an attachment for injecting the drug into the honeycomb, and at the tip of the tubular member. And an attachment for applying the medicine to the honeycomb.

  That is, the unmanned aerial vehicle can fly to a height of 8 m or more, and its flight route can be set freely. For example, a flight route is set so as to avoid tree branches, and the vicinity of the beehive or the nest It is possible to fly up or down. And since the unmanned aerial vehicle is provided with a drug supply unit, even when the nest is at a height of 8 m or more or in a tree with many branches, it supplies the nest with a drug for controlling bees. Can be easily performed. Therefore, it is possible to exterminate bees without using a conventional support pole, pole, or aerial work vehicle.

In a second aspect, in the first aspect,
An electromagnetic switching valve, which is provided on the body and switches the aerosol container between an injection state and a non-injection state, is provided.

In a third aspect, in the second aspect,
The electromagnetic switching valve can be switched between an injection state and a non-injection state by operating a controller on the ground.

  ADVANTAGE OF THE INVENTION According to 1st invention, the bee which makes a nest in a comparatively high place can be exterminated safely and promptly.

(Configuration of drug supply unit)
The medicine supply section 3 includes a cylindrical member 31 and an attachment for ejection (ejection device) 32 in addition to the aerosol container 3a and the electromagnetic switching valve 3b. The tubular member 31 constitutes a passage for a medicine, and can be constituted by, for example, a tube made of a resin material or the like. The tubular member 31 preferably has flexibility to bend, for example, when it collides with something.

  The tubular member 31 is disposed so as to protrude outward from the unmanned aerial vehicle 2 beyond the rotary wings 24 and 42 from between the two rotary wings 24 and 24 provided on the front side. As shown by the line, it is possible to change between a posture in which the leading end side in the projecting direction is located above the unmanned aerial vehicle 2 and a posture in which the leading end side in the projecting direction is located below the unmanned aerial vehicle 2. ing. The length of the tubular member 31 can be set to, for example, 50 cm or more. At the base end of the cylindrical member 31, a medicine flowing out of the electromagnetic switching valve 3b of the aerosol container 3a is introduced through a pipe (not shown).

  The injection attachment 32 is detachably attached to the distal end of the tubular member 31. Examples of the detachable structure include, for example, a structure using a screw and a tightening structure using a band. However, the structure is not limited to these, and various detachable structures can be used. The injection attachment 32 has an injection port 32a for spraying the medicine flowing through the inside of the cylindrical member 31 in the form of mist or fine particles, and the medicine is ejected from the injection port 32a by the pressure of the propellant. Injection can be performed at least 1 m or more away.

(Configuration of the posture changing unit)
In this embodiment, the attitude changing unit 4 that changes the attitude of the tubular member 31 is provided in the unmanned aerial vehicle 2. The attitude changing unit 4 is provided at a front portion of the body 20, supports a base end of the tubular member 31, and rotates the tubular member 31 around a horizontal axis extending in the left-right direction of the body 20. A mechanism 4a (shown in FIG. 4) is provided. The rotating mechanism 4a is formed of, for example, a servomotor or the like, and is controlled by a signal output from the control device 28 to change the posture of the cylindrical member 31 as shown by a virtual line in FIG. The member 31 can be fixed. The rotation angle by the rotation mechanism 4a is set to 180 °, but is not limited to this.

(How to remove bees)
Next, a bee extermination method using the bee extermination device 1 configured as described above will be described. As shown in FIG. 7, it is assumed that a nest of a bee (a hornet) is formed on a tree branch. The height of this nest is more than 8 m from the ground. There are many branches around the nest.

  First, the unmanned aerial vehicle 2 is operated from the ground by a controller to fly below the beehive to a hovering state. At this time, the unmanned aerial vehicle 2 is made to approach the nest as much as possible while visually recognizing the surrounding branches on the controller using the camera of the unmanned aerial vehicle 2. The flying object 2 must be separated from the nest to some extent.

  The controller changes the posture of the tubular member 31 by the posture changing unit 4 by operating the controller in the hovering state. That is, although not shown, by operating the upward movement button or the downward movement button on the controller, the posture changing unit 4 rotates the tubular member 31 upward or downward. The posture of the tubular member 31 is changed until the injection port 32a faces the nest. In the case of FIG. 7, since the unmanned aerial vehicle 2 can be arranged only below the nest, the tubular member 31 is directed upward. After that, the injection start button on the controller is operated. As a result, the electromagnetic switching valve 3b that has been in the non-injection state is switched to the injection state, and the poison in the aerosol container 3b flows through the tubular member 31 and is injected from the injection port 32a toward the nest, and is injected into the nest. Supplied. The poison will mainly adhere to the outer surface of the nest.

  In this embodiment, the posture changing unit 4 is of an electric type, but is not limited thereto, and may be of a manual type. In the case of the manual type, for example, before the flight, the posture of the tubular member 31 is manually changed and fixed by the operator, and in that state, the flight is started to direct the injection port 32a toward the nest.

  Here, bees form a bell-shaped nest using nest material obtained by mixing plant fibers and saliva substances (proteins) contained in the body. It has an ecological characteristic that bees are removed by investigation. In addition, when the nest is expanded, it has an ecological characteristic that it scrapes off the inner surface of the outer skin of the nest to form a colony (hexagonal room) inside the nest. Therefore, when a poison is applied to the beehive, the bee recognizes it as bait, licks it, and gives it to other bees in the nest. By killing bees, it is possible to eliminate them. In addition, when a bee rebuilds the inside of the nest, the poison can be spread throughout the nest because the husk of the nest with the poison is chewed and used as nest material inside the nest. It is possible. As described above, the use of the poison has an effect of eliminating bees in the nest.

  In addition, as shown in FIG. 8, when the unmanned aerial vehicle 2 can be arranged only above the nest, the tubular member 31 is directed downward. After that, the injection start button on the controller may be operated.

  The flight route of the unmanned aerial vehicle 2 may be set by the operator in advance of setting the flight route by inputting the coordinates of a target point or a waypoint in advance, in addition to the setting by the controller in real time as described above. 28 may be stored. In this case, after storing the flight route, the unmanned aerial vehicle 2 flies along the set flight route.

  Further, the attitude of the tubular member 31 may be changed so that the unmanned aerial vehicle 2 is caused to fly just above the honeycomb, and the injection port 32a is directed downward, so that the poison is dropped, dropped, or allowed to flow down. Alternatively, the unmanned aerial vehicle 2 may be caused to fly just below the beehive, and the posture of the tubular member 31 may be changed so that the injection port 32a faces upward, so that the poison is injected upward.

  Further, the poison may be ejected while changing the attitude of the tubular member 31. As a result, the spray range of the poison can be expanded, so that the poison can be supplied to a wide area even in a large nest.

(Effects of the embodiment)
As described above, according to this embodiment, the unmanned aerial vehicle 2 can fly to a height of 8 m or more, and its flight route can be set freely. For example, the flight route is set so as to avoid tree branches. It is possible to fly near the beehive or above or below the nest. And, since the drug supply unit 3 is provided on the unmanned aerial vehicle 2, even when the beehive is at a height of 8 m or more or in a tree with many branches, a drug for exterminating the bees is provided. It can be easily supplied to the nest. Therefore, bees that nest at relatively high places can be safely and promptly exterminated without using conventional support poles, poles and aerial work vehicles.

  Further, since the unmanned aerial vehicle 2 can be a multicopter, and the medicine supply unit 3 can be protruded from between the plurality of rotors 24, 24 so as to be positioned above the unmanned aerial vehicle 2, it is possible to use, for example, a tree. Drugs can be supplied to nests built to hang on branches and nests built under eaves.

  In addition, since the posture of the medicine supply unit 3 can be changed, extermination can be performed flexibly according to the mode of the actually formed honeycomb.

  Further, since the medicine can be jetted, the medicine can be supplied to a beehive in a place where the unmanned aerial vehicle 2 cannot access, for example, because the tree branches are dense.

  Further, since the drug can be applied or injected into the honeycomb, the influence on the surroundings can be eliminated, and the drug can be used efficiently.

  As shown in FIGS. 9 and 10, the tubular member 31 of the medicine supply section 3 may be configured to be able to expand and contract. The tubular member 31 configured to be extendable and contractable is configured by connecting a plurality of tubular portions 31a, 31b, 31c, and 31d arranged in order from the base end to the distal end, and includes a tubular portion 31d at the distal end.
