그리고, 도4는 농약 입자와 농작물이 전하에 의해 대전되어 농약이 농작물에 유착되는 상태를 설명하기 위한 도이고, 도5는 와이어와 권취부의 구조를 보인 도이다.And, Fig. 4 is a view for explaining the state in which the pesticide particles and the crop are charged by the electric charge, and the pesticide adheres to the crop, and Fig. 5 is a view showing the structure of the wire and the winding portion.

도1에서 도시한 바와 같이 본 발명에 의한 드론(100)은 프레임(111)을 포함하는 본체(110)가 구비되고, 상기 프레임(111)의 측방향으로는 방사형태로 복수의 로터(120)가 구비되어 비행이 가능하게 된다.1, the drone 100 according to the present invention is provided with a main body 110 including a frame 111, and a plurality of rotors 120 in a radial form in the lateral direction of the frame 111 Is equipped to enable flight.

상기 본체(110)의 하측에는 분부될 농약을 수용하는 농약통(140)이 장착되어 있으며, 농약통(140)의 하측으로는 수용된 농약을 펌핑하는 펌프(141)가 구비되어 있다.A pesticide container 140 for receiving the pesticide to be dispensed is mounted on the lower side of the main body 110, and a pump 141 for pumping the received pesticide is provided under the pesticide container 140.

그리고, 상기 펌프(141)로부터 양옆으로 노즐지지대(130)가 연장되어 구비되고, 이러한 노즐지지대(130)에는 농약을 지면으로 분무하기 위한 복수의 노즐(160)이 장착되어 있다.And, the nozzle support 130 is provided extending from both sides of the pump 141 to the side, the nozzle support 130 is equipped with a plurality of nozzles 160 for spraying pesticides to the ground.

또한 본체(110)의 하측 양측부로는 드론(100)이 지면에 안착하였을 때 농약통(140)과 노즐(160)이 지면에 맞닿아 손상되는 것을 방지하기 위한 지지다리(130)가 노즐(160)의 위치보다 더 하측으로 연장되어 설치되어 있다.In addition, the lower side of the main body 110 has a support leg 130 for preventing the pesticide container 140 and the nozzle 160 from coming into contact with the ground and being damaged when the drone 100 is seated on the ground. ) Extends downward and is installed.

상기 본체(110)의 내측에는 도2에서와 같이 컨트롤러(112), 배터리(113), 통신부(114), 스위치(115), 노즐(160)이 구비되어 있는데, 상기 컨트롤러(112)는 통신부(114)를 통하여 조작자가 소지한 리모트 컨트롤러로부터 비행 제어명령 및 농약 분무 명령을 인가받아 로터(120)를 제어하게 되고, 또한 배터리(113)와 노즐(114) 사이에 구비된 스위치(115)를 온/오프 하여 노즐(114)에 '-'전압의 인가여부를 결정한다.As shown in FIG. 2, a controller 112, a battery 113, a communication unit 114, a switch 115, and a nozzle 160 are provided inside the main body 110, wherein the controller 112 includes a communication unit ( 114) to control the rotor 120 by receiving a flight control command and a pesticide spray command from a remote controller possessed by the operator, and also turns on the switch 115 provided between the battery 113 and the nozzle 114. It is determined whether the '-' voltage is applied to the nozzle 114 by turning it on / off.

또한, 펌프(141)를 구동시켜 농약통(140)에 수용된 농약이 압력을 가지고, 노즐지지대(150)를 통해 노즐(160)로 공급되도록 함으로써 분무가 이루어지도록 하는 것이다.In addition, spraying is performed by driving the pump 141 so that the pesticide contained in the pesticide container 140 has a pressure and is supplied to the nozzle 160 through the nozzle support 150.

상기 노즐(160)은 배터리(113)로부터 '-'전압을 인가받아 분무되는 농약 입자가 (-)전하를 띠도록 하는데, 도3에서와 같이 노즐 몸체(161)의 하측에는 농약이 외부로 분무되는 분무공(162)이 형성되고, 그 분무공(162)의 주변 둘레를 따라서는 링 형태의 '-'전극(163)이 장착되어 있으며, 이러한 '-'전극(163)은 절연부(164)에 의해 몸체(161)와 절연된 상태를 유지하게 된다.The nozzle 160 is applied to the '-' voltage from the battery 113 so that the sprayed pesticide particles have a negative charge, as shown in FIG. 3, the pesticide is sprayed to the outside of the nozzle body 161. A spray hole 162 is formed, and a ring-shaped '-' electrode 163 is mounted along the periphery of the spray hole 162, and the '-' electrode 163 is an insulating part 164 ) To maintain an insulated state from the body 161.

따라서, 분무공(162)을 통해 분무되는 농약은 '-'전극(163)을 통과하면서 (-)전하를 띠게 되어 하측으로 분무된다.Therefore, the pesticide sprayed through the spray hole 162 passes through the '-' electrode 163 and has a negative charge, so it is sprayed downward.

이렇게 분무되는 (-)전하를 띠는 농약 입자는 도4에서와 같이 농작물(P)이 띠는 (+)전하와 대전되며, 이로 인해 크게 비산되지 않으면서 농작물(P) 방향으로 유도된다.The sprayed (-) charge-generated pesticide particles are charged with the (+) charge of the crop (P) as shown in FIG. 4, thereby leading to the crop (P) direction without being significantly scattered.

또한 농약물(P) 잎의 상부면에 유착되지 않고 지면(G) 방향으로 떨어지는 농약 입자도 농작물(P) 잎의 저면에 분포된 (+)전하와 대전하여 유도됨으로써 다시 유착되는 것이다.In addition, pesticide particles that do not adhere to the upper surface of the pesticide (P) leaf and fall in the direction of the ground (G) are re-adhered by being induced by charging with the (+) charge distributed on the bottom surface of the crop (P) leaf.

농작물(P)은 (+)전하와 (-)전하가 균일하게 분포되어 있으므로, (-)전하를 띠는 농약 입자가 농작물(P)의 상부면과 저면부에 분포된 (+)전하와 대전됨으로써 고르게 유착되는 것이다.Since the (+) charge and the (-) charge are uniformly distributed in the crop (P), the (+) charge and the charge of the pesticide particles with the (-) charge are distributed in the upper and lower surfaces of the crop (P). By doing so, it adheres evenly.

이로 인하여 비산되는 농약의 양이 줄어들게 됨과 아울러, 농약 입자가 농작물에 고르게 분포되도록 유착됨으로써 방제 효과가 매우 뛰어나게 되는 것이다.Due to this, the amount of pesticides scattered is reduced, and the control effect is very excellent by coalescing such that the pesticide particles are evenly distributed in the crops.

한편, 노즐(160)에 '-'전압을 인가한 상태에서, 본체(110)를 지면(G)에 접지시키기 위하여 본체(110)로부터 지면(G)까지 도전성을 갖는 금속성의 와이어(170)가 연결된다.On the other hand, in the state in which '-' voltage is applied to the nozzle 160, the metallic wire 170 having conductivity from the body 110 to the ground G is grounded to ground the main body 110 to the ground G.

즉, 낙뢰 등에 의하여 드론(100)이 손상되는 것을 방지하기 위하여 접지를 행하는 것이 바람직한데, 이를 위하여 와이어(170)의 일측은 본체(110)에 연결되고, 타측은 지면(G)에 접속하게 되며, 이때 지면(G)과의 접촉력을 증대시키기 위하여 와이어(170)의 타단 즉 지면과 접촉하는 부위에는 중량의 추(171)가 고정되어 있다.That is, it is preferable to perform grounding to prevent the drone 100 from being damaged by lightning, etc. To this end, one side of the wire 170 is connected to the main body 110 and the other side is connected to the ground G, At this time, in order to increase the contact force with the ground (G), a weight 171 of the weight is fixed to the other end of the wire 170, that is, a portion in contact with the ground.

따라서, 드론(100)이 측방향으로 이동하여도 와이어(170)가 흩날리지 않고 추(171)로 인하여 드론(100)에 끌리면서 지면(171)에 안정적으로 접지된 상태에서 이동이 가능하게 되는 것이다.Therefore, even when the drone 100 moves in the lateral direction, the wire 170 is not scattered and can be moved in a state of being stably grounded on the ground 171 while being dragged by the drone 100 due to the weight 171. will be.

드론(100)의 비행 높이에 따라 이러한 와이어(170)의 길이가 조절되도록 함이 바람직한데, 드론(100)의 비행 높이보다 와이어(170)의 길이가 너무 긴 경우에 와이어(170)가 농작물(P)에 걸려서 손상을 줄 수 있기 때문에 가급적 와이어(170)는 지면(G)에 끌리지 않도록 드론(100)의 비행 높이와 와이어(170)의 길이가 비슷하여야 한다.It is preferable to adjust the length of the wire 170 according to the flight height of the drone 100. When the length of the wire 170 is too long than the flight height of the drone 100, the wire 170 is a crop ( As possible, the wire 170 should be of the same height as the flight height of the drone 100 and the length of the wire 170 so that the wire 170 is not dragged by the ground G because it may be damaged by the P).

이를 위해서 본체(110)의 하측에는 와이어(170)가 권취되는 권취부(180)가 구비되는데, 이러한 권취부(180)는 도5에 도시한 바와 같이 모터(181)와, 모터(181)의 정회전 및 역회전에 의해 와이어(170)를 풀거나 감는 권취드럼(182)으로 구성되어 있다.To this end, a winding portion 180 in which the wire 170 is wound is provided on the lower side of the main body 110, and the winding portion 180 includes a motor 181 and a motor 181 as shown in FIG. It is composed of a winding drum 182 that unwinds or winds the wire 170 by forward rotation and reverse rotation.

따라서, 조작자가 자신의 리모트 컨트롤러에 의해 와이어(170)의 길이를 조작하는 명령을 드론(100)으로 전송하게 되면, 컨트롤러(112)는 이를 통신부(114)를 통해 인가받아 모터(181)의 정회전 및 역회전을 제어하게 된다.Accordingly, when the operator transmits a command to manipulate the length of the wire 170 by the remote controller to the drone 100, the controller 112 receives it through the communication unit 114 and determines the motor 181. Rotation and reverse rotation are controlled.

즉, 드론(100)의 비행 높이보다 와이어(170)의 길이가 짧다면, 조작자의 조작에 의해 모터(181)를 정회전시켜 와이어(170)를 풀게 되고, 반대로 와이어(170)의 길이가 길다면 모터(181)를 역회전시켜 와이어(170)를 감게 되는 것이다.That is, if the length of the wire 170 is shorter than the flight height of the drone 100, the motor 181 is rotated forward by the operator's operation to loosen the wire 170, and conversely, if the length of the wire 170 is long The wire 170 is wound by rotating the motor 181 in reverse.

또 다르게는 본체의 하부에 거리감지센서(190)를 구비하여 지면(G)과의 거리를 측정하게 되고, 그 거리 정보를 컨트롤러(112)에서 인가받아 와이어(170)의 길이를 조절하게 되는데, 권취드럼(182)의 정회전 또는 역회전의 회전수에 따른 와이어(170)의 길이를 알 수 있으므로, 컨트롤러(112)는 그 거리 정보에 따라 모터(181)의 회전수를 제어하여 드론(100)의 비행 높이에 따라 와이어(170)의 길이를 자동으로 조절할 수 있는 것이다.Alternatively, a distance detection sensor 190 is provided at the bottom of the main body to measure the distance from the ground G, and the distance information is applied from the controller 112 to adjust the length of the wire 170. Since the length of the wire 170 according to the number of revolutions of the forward or reverse rotation of the take-up drum 182 is known, the controller 112 controls the number of revolutions of the motor 181 according to the distance information to drone 100 ) It is possible to automatically adjust the length of the wire 170 according to the flight height.

즉, 드론(100)의 비행 높이가 5m이고, 권취드럼(182)의 외경이 30cm이면, 와이어(170)가 완전히 감긴 상태에서 권취드럼(182)을 6회 정회전시켜 와이어(170)의 하단부 즉 추(171)가 지면에 닿도록 한다.That is, if the flight height of the drone 100 is 5m, and the outer diameter of the winding drum 182 is 30cm, the winding drum 182 is rotated six times in the state where the wire 170 is completely wound, and the lower end of the wire 170 That is, the weight 171 is brought into contact with the ground.

또한, 컨트롤러(112)는 거리감지센서(190)로부터 일정간격(예를 들면 0.1~0.5초)마다 거리 정보를 입력받아 드론(100)의 비행 높이가 변경되는 경우에도 모터(181)를 제어하여 항상 와이어(170)가 지면에 안정적으로 접촉하도록 하는 것이다.In addition, the controller 112 receives the distance information at regular intervals (for example, 0.1 to 0.5 seconds) from the distance sensor 190 to control the motor 181 even when the flight height of the drone 100 changes. This is to ensure that the wire 170 always stably contacts the ground.

아울러, 드론(100)이 지면에 착륙하는 경우에도, 지면과의 거리에 따라 와이어(170)가 자동으로 권취드럼(182)에 감기게 됨으로써 조작자가 수동으로 조작하지 않아도 되는 것이다.In addition, even when the drone 100 lands on the ground, the wire 170 is automatically wound around the winding drum 182 according to the distance from the ground, so that the operator does not need to manually operate the wire.
