It is to provide a chemical solution supply structure of the spraying medicine table invented so as to increase the range and increase the degree of diffusion when spraying the chemical solution.

분사 약대는 수동/자동 구동방식의 살포용 장치에 부가하여 약액(농약)이나 각종 액상 물질의 살포에 사용할 수 있도록 개발한 장치이다.Spraying medicine table is a device developed to be used for spraying chemicals (pesticides) or various liquid substances in addition to manual/automatic driving type spraying devices.

상기한 분사 약대는 사용자가 파지한 상태에서 살포장치에서 공급되는 약액을 안정적으로 살포하여 줄 수 있도록 해주기 위한 농약 살포장치의 구성부품이다.The spraying camel is a component of a pesticide spraying device for stably spraying the chemical solution supplied from the spraying device while the user is holding it.

통상의 분사 약대(10)는 선단 및 후단에 분사 노즐구(30) 및 조절손잡이(23)를 각각 결합한 약대 파이프(20)의 일측에 약액 살포장치에 연계되는 약액 공급관의 연결을 위한 약액 공급구(21) 및 파지구(22)를 각각 형성하여 구성하고 있으며,(도 1 참조) 분사 약대(10)는 조절손잡이(23)에 의해 약액 공급량이 조절되는 분사 노즐구(30)의 작용에 의해 직사 또는 분무 형태로 약액을 살포하여 줄 수 있도록 한 것이다.A typical spraying medicine stand 10 has a chemical solution supply port for connecting a chemical solution supply pipe connected to a chemical solution spraying device to one side of a medicine stick pipe 20 to which a spray nozzle port 30 and a control knob 23 are respectively coupled at the front and rear ends.

도 1에 분사 약대(10)의 하나의 실시예가 도시되는데, 도시된 바를 통해 본 발명은 약액 공급구(21) 및 파지구(22), 조절손잡이(23)를 구비하는 약대 파이프(20) 선단에 분사 노즐구(30)를 결합하여 분사 약대(10)를 구성한 것임을 확인할 수 있다.1 shows an embodiment of a spraying medicine stand 10, and through the drawing, the present invention is a medicine medicine supply port 21, a gripper 22, and a front end of a medicine stick pipe 20 having a control knob 23 It can be seen that the spray nozzle 30 is combined to form the spray medicine stand 10.

도 2에 본 발명에 따른 약액 공급 구조를 설명하기 위한 참고 분해 사시도가 도시되고, 도 3에 본 발명에 따른 약액 공급 구조를 결합상태를 설명하기 위한 참고 단면도가 도시되는데, 도시된 바와 같이 분사 노즐구(30)의 노즐 몸체(31)를 관통하는 약액 송출공(33)의 선단에 분사 노즐(37)을 결합한다.2 is a reference exploded perspective view for explaining the chemical solution supply structure according to the present invention, and FIG. 3 is a reference cross-sectional view for explaining the coupling state of the chemical solution supply structure according to the present invention. The injection nozzle 37 is coupled to the front end of the chemical delivery hole 33 penetrating the nozzle body 31 of the sphere 30.

상기 약액 송출공(33)의 후단부에 축방향에서 보았을 때 방사상으로 돌출하는 형태를 취하는 적어도 2개 이상의 확장공(34)을 형성하며, 상기 약액 송출공(33)에 수용되는 직경을 가지는 공급 조절부재(35)를 결합한다.At least two or more expansion holes 34 protruding radially when viewed from the axial direction are formed at the rear end of the chemical solution delivery hole 33, and the supply hole has a diameter accommodated in the chemical delivery hole 33. The adjusting member 35 is coupled.

상기 확장공(34)은 약액 송출공(33)의 후단부 일정 영역에 이르는 길이(L1)를 갖도록 형성되는 것으로, 확장공(34)의 길이(L1)는 공급 조절부재(35)의 규격에 의해 설정된다.The expansion hole 34 is formed to have a length L1 reaching a certain area at the rear end of the chemical delivery hole 33, and the length L1 of the expansion hole 34 conforms to the standard of the supply control member 35. is set by

상기 확장공(34)은 2개 이상의 수량으로 조합하여 구성할 수 있는데, 자체적인 테스트에 의하면 등간격을 유지하는 4개의 확장공(34)을 방사상으로 배치하였을 때 약액의 살포효율이 가장 우수하게 나타났다.The expansion holes 34 can be configured by combining two or more numbers. According to our own test, when four expansion holes 34 maintaining equal intervals are arranged radially, the spraying efficiency of the chemical solution is the best. appear.

상기한 공급 조절부재(35)의 후방에 결합되는 연결로드(L)를 조절손잡이(23)에 연결하여, 조절손잡이(23)의 정,역회전 구동에 의해 공급 조절부재(35)가 약액 송출공(33) 후단부에서 전,후진되도록 한다.By connecting the connecting rod (L) coupled to the rear of the supply control member 35 to the control knob 23, the supply control member 35 supplies the chemical solution by forward and reverse rotation of the control knob 23. The ball 33 moves forward and backward at the rear end.

상기 공급 조절부재(35)의 외주면에는 나선형 공급홈(36)을 형성하여, 나선형 공급홈(36)을 따라 약액이 분사 노즐(37)로 공급되도록 분사 약대의 약액 공급 구조를 구성한다.A spiral supply groove 36 is formed on the outer circumferential surface of the supply control member 35, so that the chemical solution is supplied to the spray nozzle 37 along the spiral supply groove 36.

본 발명에 따른 확장공(34)을 구성함에 있어서, 확장공(34)의 축방향 길이(L1)는 상기 공급 조절부재(35)의 몸체 길이(L2)를 수용할 수 있는 길이 이상으로 형성하는 것이 바람직한데, 그 이유는 확장공(34)이 공급 조절부재(35)를 온전하게 수용할 수 있도록 구성함으로써 확장공(34)으로 공급된 약액의 1차 가압이 이루어지고 1차 가압된 약액이 공급 조절부재(35)의 나선형 공급홈(36)을 따라 이동하면서 2차 가압과 와류현상이 발생하도록 작용할 수 있기 때문이다.In configuring the expansion hole 34 according to the present invention, the axial length L1 of the expansion hole 34 is formed to be longer than the length that can accommodate the body length L2 of the supply control member 35 Preferably, the reason is that by configuring the expansion hole 34 to fully accommodate the supply control member 35, the chemical solution supplied to the expansion hole 34 is firstly pressurized, and the first pressurized chemical solution This is because it can act to generate secondary pressure and vortex while moving along the spiral supply groove 36 of the supply control member 35.

이상의 구성으로 된 본 발명은 농약 살포장치(미도시됨)와 연계되는 약액 공급관을 약액 공급구(21)에 연결하여, 농약 살포장치에서 공급되는 약액을 살포하여 줄 수 있도록 한 것으로, 약액 공급구(21)를 통해 공급된 약액은 약대 파이프(20)를 경유하여 분사 노즐(37)을 통해 분사되는 것이다.The present invention having the above configuration connects the chemical solution supply pipe associated with the pesticide spraying device (not shown) to the chemical solution supply port 21 so that the chemical solution supplied from the pesticide spraying device can be sprayed, and the chemical solution supply port The chemical solution supplied through (21) passes through the camel pipe (20) and is sprayed through the spray nozzle (37).

본 발명이 적용된 분사 약대(10)를 이용하여 분무 형태의 약액 살포작업을 진행하고자 할 경우에는 조절손잡이(23)를 정회전 조작함으로써 공급 조절부재(35)를 전진시켜 공급 조절부재(35)의 선단부가 확장공(34)의 선단에 위치하도록 조절한 상태(도 5 [A] 참조)에서 약액을 공급하게 되면, 확장공(34)으로 약액이 공급되면서 1차 가압이 이루어지고 공급 조절부재(35)의 나선형 공급홈(36)을 따라 공급되는 약액이 2차 가압과 와류현상을 일으키며 분사 노즐(37)의 노즐공을 통과하여 살포되므로 증진된 수압과 와류현상에 의해 분무형태로 살포되는 약액의 확산도를 향상시킬 수 있는 것이다.When spraying a chemical solution in the form of a spray using the spraying camel 10 to which the present invention is applied, the supply control member 35 is moved forward by operating the control knob 23 forward to rotate the supply control member 35. When the chemical solution is supplied in a state in which the tip is adjusted to be located at the tip of the expansion hole 34 (see FIG. 5 [A]), the chemical solution is supplied to the expansion hole 34 and the first pressurization is performed, and the supply control member ( 35), the chemical solution supplied along the spiral supply groove 36 is sprayed through the nozzle hole of the injection nozzle 37 with secondary pressurization and vortex phenomenon, so the chemical solution sprayed in the form of spray by the increased water pressure and vortex phenomenon can improve the diffusivity of

본 발명이 적용된 분사 약대(10)를 이용하여 직사 형태의 약액 살포작업을 진행하고자 할 경우에는 조절손잡이(23)를 역회전 조작함으로써 공급 조절부재(35)를 후진시켜 공급 조절부재(35)의 선단부가 확장공(34)의 선단으로부터 이탈되도록 조절한 상태(도 5 [B] 참조)에서 약액을 공급하게 되면, 나선형 공급홈(36)을 따라 와류현상을 일으키며 공급되는 약액이 확장공(34)에서 가압이 이루어지며 공급 조절부재(35)의 선단영역에 모여 분사 노즐(37)의 노즐공을 통과하여 살포되므로 약액의 직사 살포거리를 향상시킬 수 있는 것이다.In the case of using the spraying camel 10 to which the present invention is applied, when it is desired to spray the chemical solution in the form of direct yarn, the supply control member 35 is reversed by operating the control knob 23 to reverse the supply control member 35. When the chemical solution is supplied in a state where the tip is adjusted to be separated from the tip of the expansion hole 34 (see FIG. 5 [B]), a vortex phenomenon occurs along the spiral supply groove 36, and the supplied chemical solution flows through the expansion hole 34 ), pressurization is made, and since the chemicals are collected at the front end area of the supply control member 35 and sprayed through the nozzle hole of the spray nozzle 37, the direct spraying distance of the chemical solution can be improved.

본 발명에서 제시하는 분사 약대의 약액 공급 구조는 전술하고 있는 실시예 및 첨부된 도면 등에 의해 한정되는 것은 아니라 할 것이며, 본 발명에서 향유하고자 하는 기술적 사상의 범주를 벗어나지 않는 범위 내에서는 다양한 형태로 치환, 변형 및 변경을 가할 수 있는 것인바, 이는 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에게 있어서 자명하다 할 것이다.The chemical solution supply structure of the sprayed camel presented in the present invention will not be limited by the above-described embodiments and the accompanying drawings, etc., and can be substituted in various forms within the scope of the technical idea to be enjoyed in the present invention. , Modifications and changes can be added, which will be apparent to those skilled in the art to which the present invention belongs.
