본 발명을 첨부한 도면을 참조하여 상세히 설명한다.The present invention will be described in detail with reference to the accompanying drawings.

도2는 본 발명의 농약 분무 장치의 외관 구조를 보인 도이고, 도3은 측단면을 보인 도로서, 내부가 비어있는 원통체로 되고 양측이 막혀있는 이동체(200)가 구비되는데, 상기 이동체(200)는 길이방향으로 양측이 단부로 갈수록 좁아지도록 경사부(201,202)가 형성되어 있다.Figure 2 is a view showing the outer structure of the pesticide spraying apparatus of the present invention, Figure 3 is a side cross-sectional view, the inside is a hollow cylindrical body is provided with a mobile body 200 is blocked on both sides, the mobile body 200 ) Are inclined portions 201, 202 are formed so that both sides become narrower toward the end in the longitudinal direction.

상기 경사부(201,202)는 이동체(200)의 양측에서 모두 형성될 수도 있고, 어느 일측 즉, 이동체(200)가 이동하는 선단부위에서만 경사부(202)가 형성될 수 있을 것이다.The inclined portions 201 and 202 may be formed at both sides of the movable body 200, or the inclined portions 202 may be formed only at one side, that is, the tip portion where the movable body 200 moves.

또한, 이동체(200)의 양단은 각각 덮개(230,240)에 의해 폐쇄되는데, 이때 각 덮개(230,240)의 중심부위는 관통된 구멍이 형성되고, 그 구멍에 베어링(231,241)이 장착되어 있다.In addition, both ends of the movable body 200 are closed by the lids 230 and 240, respectively. In this case, through holes are formed in the centers of the lids 230 and 240, and bearings 231 and 241 are mounted in the holes.

따라서, 직관형태의 내부관체(210)가 베어링(231,241)을 통해 이동체(200)를 가로방향으로 관통하여 삽입되며, 이러한 내부관체(210)는 베어링(231,241)에 의해 자유회전이 가능하게 된다.Therefore, the inner tube 210 having a straight tube shape is inserted through the moving body 200 in the horizontal direction through the bearings 231 and 241, and the inner tube 210 can be freely rotated by the bearings 231 and 241.

또한, 내부관체(210)의 외측에는 지면을 향하도록 편심되게 추(220)가 일체로 설치되며, 이러한 추(220)도 이동체(200)의 내측에 위치하게 된다.In addition, the weight 220 is integrally installed on the outside of the inner tube body 210 so as to face the ground, such a weight 220 is also located inside the moving body 200.

상기 내부관체(210)의 일단 즉, 이동체(200)의 일측으로 노출된 단부에는 원격지로부터 가압된 농약을 이송시키는 농약호스(330)가 꼬임풀리(280)에 의해 연결되는데, 이때 꼬임풀리(280)는 내부관체(210)가 회전시 농약호스(330)와의 꼬임을 방지하기 위하여 접속되는 구조이며, 이러한 구조는 일반적인 구조이므로 구체적인 구조는 도시하지 않았다.One end of the inner tube 210, that is, the end exposed to one side of the moving body 200 is connected to the pesticide hose 330 for transferring the pesticide pressurized from a remote place by the twist pulley 280, the twist pulley 280 ) Is a structure in which the inner tube 210 is connected to prevent twisting with the pesticide hose 330 during rotation, and since such a structure is a general structure, a specific structure is not shown.

내부관체(210)가 이동체(200)의 타측으로 노출된 타단에는 'T'형태의 연결소켓(250)이 접속되고, 상기 연결소켓(250)에는 지면으로부터 직립되도록 추(220)와는 반대방향으로 노즐관체(260)가 접속되며, 이 노즐관체(260)에는 다수의 노즐(261)이 일정간격으로 설치되어 있다.The other end of the inner body 210 is exposed to the other side of the moving body 200, the connection socket 250 of the 'T' type is connected, the connection socket 250 in the opposite direction to the weight 220 so as to stand up from the ground The nozzle pipe 260 is connected, and the nozzle pipe 260 is provided with a plurality of nozzles 261 at regular intervals.

이때, 추(220)가 지면을 향하게 되면, 노즐관체(260)는 직립되며, 이동체(200) 또는 노즐관체(260)가 외력에 의해 흔들리더라도 추(220)가 지면을 향하면서 안정되므로 노즐관체(260)는 항시 직립된 상태를 유지하게 된다.At this time, when the weight 220 is directed to the ground, the nozzle tube 260 is upright, even if the moving body 200 or the nozzle tube 260 is shaken by an external force, the weight 220 is stabilized while facing the ground nozzle The tubular body 260 is always kept upright.

즉, 추(220)가 지면을 향하면서 흔들림이 안정되면, 내부관체(210)도 베어링(231,241)에 의해 회전하다가 안정되며, 노즐관체(260)도 지면으로부터 직립되도록 안정되는 것이다.That is, when the weight is stabilized while the weight 220 is toward the ground, the inner tube 210 also rotates by the bearings 231 and 241, and the nozzle tube 260 is also stabilized to stand upright from the ground.

노즐(260)은 노즐관체(260)의 양측, 즉 노즐관체(260)가 회전하는 양측에 각각 구비된다.The nozzles 260 are provided at both sides of the nozzle tube 260, that is, at both sides of which the nozzle tube 260 rotates.

그리고, 이동체(200)의 선단에는 와이어를 걸기위한 와이어 걸고리(270)가 구비되는데, 이러한 와이어 걸고리(270)는 바람직하게 노즐대(260)의 전방인 연결소켓(250)의 전방외측에 위치하게 되어 와이어가 노즐관체(260)에 감기는 것을 방지하는 것이 좋다.In addition, the front end of the movable body 200 is provided with a wire hook 270 for hooking a wire, such a wire hook 270 is preferably located in front of the outside of the connecting socket 250, which is the front of the nozzle unit 260. It is good to prevent the wire from being wound around the nozzle tube 260.

따라서 농약호스(330)를 통해 원격지로부터 가압된 농약이 내부관체(210)를 통해 노즐관체(260)로 유입되어 노즐(261)을 통해 분무되는데, 노즐(261)이 노즐관체(260)의 양측에 구비되어 있으므로, 도4에서와 같이 노즐관체(260)를 중심으로 양측으로 분무되어 농약의 분무압력에 의해 노즐관체(260)가 어느 한쪽 방향으로 회전되는 것을 방지하게 됨과 아울러 고랑 양측의 논밭에 동시에 농약을 분무할 수 있게 된다.Therefore, the pesticide pressurized from a remote place through the pesticide hose 330 is introduced into the nozzle tube 260 through the inner tube 210 and sprayed through the nozzle 261, the nozzles 261 are both sides of the nozzle tube 260 4 is sprayed to both sides around the nozzle tube 260 as shown in FIG. 4 to prevent the nozzle tube 260 from rotating in either direction due to the spraying pressure of the pesticide, and to the paddy fields on both sides of the furrow. Pesticides can be sprayed at the same time.

도5는 본 발명의 사용상태를 설명하기 위한 도로서, 논발의 고랑사이에 이동체(200)를 위치시키고, 와이어(340)가 이동하는 경로상에 아이들 롤러(350,351)를 설치한 다음 와이어 당김롤러(360)에 의해 와이어(340)를 당기게 되면, 이동체(200)가 고랑사이를 이동하면서 원격지의 차량(300)에 탑재된 동력호스릴(310)이 회전하면서 농약호스(330)가 풀리게 되고, 이로인해 약통(320)의 농약이 가압되어 이동체(200)로 공급된다.5 is a view for explaining the use state of the present invention, the mobile body 200 is located between the furrows of the rice paddle, and the wire pulling rollers are installed after the idle rollers 350 and 351 are installed on the path where the wire 340 moves. When the wire 340 is pulled by the 360, while the moving body 200 moves between the furrows, the pesticide hose 330 is released while the power hose reel 310 mounted on the remote vehicle 300 rotates. As a result, the pesticide of the medicine container 320 is pressurized and supplied to the mobile body 200.

따라서 고랑 양측에 농약이 분무되는 것이다.Therefore, pesticide is sprayed on both sides of the furrow.

이때, 이동체(200)의 양단에 경사부(201,202)가 형성되어 있으므로, 고랑사이의 불규칙한 지면을 바퀴가 없이도 타고 넘을 수 있어서 이동체(200)의 이동에 부하가 크게 걸리지 않게 된다.At this time, since the inclined portions 201 and 202 are formed at both ends of the movable body 200, the irregular ground between the furrows can be carried over without a wheel, so that the load of the movable body 200 is not largely taken.

와이어 당김롤러(360)는 동력에 의해 와이어를 당기는 구조를 갖는다.Wire pulling roller 360 has a structure that pulls the wire by the power.

결국, 이동체(200)가 이동하면서 회전할지라도 추(220)에 의해 노즐관체(260)가 직립상태를 유지할 수 있어서 농약이 올바르게 분무되며, 사람이 직접 이동체(200)를 이동하지 않고 동력에 의해 일정하게 와이어를 당김으로써 농약이 고르고 적절하게 농작물에 분무된다.
As a result, even if the moving body 200 rotates while moving, the nozzle tube 260 can maintain the upright state by the weight 220, so that the pesticide is sprayed correctly, and a person does not move the moving body 200 directly by power. By constantly pulling the wire, the pesticide is evenly and properly sprayed on the crop.
