일반적인 드론(Drone)은 상황·목적·국가별로 다양한 용어로 불리는데, 일반적으로 무선전파로 조종할 수 있는 무인항공기(UAV, Unmanned AerialVehicle)를 뜻하는 것으로 사람이 탑승하지 않고 무선전파 유도에 의해 비행조종이 가능한 비행기나 헬리콥터 모양의 무인기를 총칭한다.A general drone is called a variety of terms for each situation, purpose, and country, and generally refers to an unmanned aerial vehicle (UAV) that can be controlled by radio waves. Flight control by radio wave guidance without a person on board. This is a generic term for an airplane or helicopter-shaped UAV.
이러한 드론의 종류 중, 방제드론은 넓은 농지에서 알맞은 고도를 유지하며 적절량의 약제를 고르게 분사할 수 있는 장점이 있다.Among these types of drones, control drones have the advantage of maintaining an appropriate altitude over a wide farmland and spraying an appropriate amount of drugs evenly.
방제드론은 약통을 분리형으로 결합하는 방식을 취하고 있으며, 약제 분사를 하방향으로 분무하는 구조를 취하고 있고, 하부에는 풋(Foot)에 해당하는 레그 구조물, 상부에는 비행을 위한 프로펠러 구조물 등의 복잡하게 결합되어 있는 구조이다.Control drones take a method of combining medicine barrels in a separate type, and take a structure to spray the drug in the downward direction, in the lower part the leg structure corresponding to the foot, and the upper part in the complicated propeller structure for flight. It is a combined structure.
그러나, 이러한 구조는 과수원 등의 과수가 열리는 임목장에서는 과수의 가지나 과수원의 바닥 등에 드론의 구조물이 걸려 효율적인 비행이 어려워 실효적인 방제기능을 하지 못하는 문제가 있고, 보다 간결하고 이동성이 좋은 구조의 드론이 필요하다.However, such a structure has a problem that effective flight is difficult due to the fact that the structure of the drone is caught in the branches of the fruit tree or the floor of the orchard in the forest ranch where fruit trees such as orchards are opened, and the drone has a more concise and mobile structure. I need this.
과수의 경우, 열매가 나무 내부에 열리는 경우가 대부분인 바, 하방향 분사구조는 직접적으로 열매에 약제를 분사하기 어려우며, 이에 상방향 분사 기능을 구현할 드론이 필요하다.In the case of fruit trees, in most cases, the fruit is opened inside the tree, and the downward spray structure makes it difficult to directly spray the drug onto the fruit, and thus a drone to implement the upward spray function is required.
본 발명은 상술한 문제를 해결하기 위하여 안출된 것으로, 본 발명의 목적은 약제와 같은 유체를 수용하는 약통을 프로펠러유닛이나 제어유닛을 매립하는 구조의 하우징으로 활용하여, 드론의 외부에 노출되는 요소를 최소화함으로써, 방제드론의 방제시 발생하는 드론의 장애물과의 충돌을 최소화하여 방제 기능을 극대화할 수 있는 드론 구조를 제공하는 데 있다.The present invention was conceived to solve the above-described problem, and an object of the present invention is to utilize a medicine container containing a fluid such as a drug as a housing of a structure to bury a propeller unit or a control unit, and the element exposed to the outside of a drone By minimizing, it is to provide a drone structure that can maximize the control function by minimizing the collision with the obstacle of the drone that occurs during the control of the control drone.

It has the effect of maximizing the control function by minimizing the collision with the obstacle of the drone that occurs during the event.
또한, 드론의 몸체의 내부에 분사유닛을 매립구조로 설치하며, 분사노즐의 방향을 상부 또는 하부 자유자재로 전환이 가능하도록 하여, 과수의 하부에서 상부로의 다방향 분사가 가능하도록 함으로써, 약제 살포의 효율성을 확보할 수 있는 장점이 구현된다.In addition, the injection unit is installed in the interior of the drone body in a buried structure, and the direction of the injection nozzle can be freely switched to the upper or lower part, thereby enabling multi-directional injection from the lower part of the fruit tree to the upper part. The advantage of securing the efficiency of spraying is realized.
