Abstract

The present invention relates to a leakage prevention device for a rotary sprayer. A rotating bundle (2) of the rotary sprayer is formed by a body (2a) and a cap (2b). The body (2a) has a pair of bearings (B, B') installed therein before and after an inner diameter portion (2a'). Teflon packings (22, 22') are installed between the bearing (B) and the bearing (B'). In this case, the Teflon packing (22) is inserted in the body by using an interference fit method so that there is no gap between the outer diameter and the inner diameter of the inner diameter portion (2a') to act integrally with the body (2a). The inner diameter is formed to be greater than the outer diameter of a central pipe (4) so that the inner diameter portion does not touch the central pipe (4). The Teflon packing (22') is in close contact with the side of the Teflon packing (22) to cause friction. A spring (23) with strong elasticity is interposed between the Teflon packing (22') and the bearing (B') to push the same as the friction surfaces of the Teflon packing (22, 22') are worn to stably block leakage. Thus, the leakage prevention device for a rotary sprayer enables smooth rotation and stably prevents leakage at all times. Therefore, the leakage prevention device for a rotary sprayer can make the rotation due to a reaction to spraying very smooth when a head (1) rotates while a liquid is sprayed, thereby further increasing liquid spray efficiency and maximizing a leakage blocking effect.

Description

회전분사기의 누수방지장치{A sprayer for agricultural}Leak prevention device of rotary sprayer {A sprayer for agricultural}

본 발명은 농업용수, 농약, 액비 등의 액재를 분사할 때 발생하는 반작용을 이용하여 2~4개의 노즐대가 분사방향과 반대방향으로 자동 회전하고, 이때 분사되는 액재가 회오리 형태로 되어 자연스럽게 멀리까지 분무 또는 분사될 수 있게 한 농약살포용 회전분사기에 있어서, 회전이 부드러우면서 안정적으로 이루어지고 누수 또한 전혀 발생되지 않게 함으로써, 종래 방제과정에서 누수로 인한 낙수가 작물의 잎이나 줄기, 또는 토양에 집중적으로 작용하여 작물에 피해를 주게 되는 등의 문제점을 사전에 예방할 수 있게 하기 위한 회전분사기의 누수방지장치에 관한 것이다.In the present invention, by using the reaction generated when liquid materials such as agricultural water, pesticides, and liquid manure are sprayed, two to four nozzles automatically rotate in the opposite direction to the spraying direction, and at this time, the liquid materials sprayed form a whirlwind and travel far away naturally. In the rotary sprayer for spraying pesticides that can be sprayed or sprayed, the rotation is performed smoothly and stably and no leakage occurs, so that water droplets due to water leakage in the conventional control process may fall on the leaves, stems, or soil of crops. It relates to a leak prevention device of a rotary sprayer for preventing problems such as damage to crops by acting intensively in advance.

일반적으로, 농가와 도심에서는 각종 유해 해충으로부터 농작물은 물론, 과수, 가로수 등의 나무방제나, 축사방제 등을 위한 약제를 살포하는 것이 보편화되고 있으며, 이러한 액상의 약제를 분무하거나 살포하기 위하여 다양한 액상분사기 또는 분무기가 개발 및 사용되고 있다.In general, in farms and urban areas, it is common to spray chemicals for crops, fruit trees, street trees, etc., or livestock control, as well as crops from various harmful pests. Injectors or atomizers are being developed and used.

상기한 액상의 분사기는 사용자가 수작업으로 펌핑하여 약제가 분사되도록 하는 수동식에서부터 동력을 이용한 동력분사방식의 동력분사기 등 다양하게 보급되고 있으며, 단순히 약제가 확산되는 기능만 되어 있는 것이 대부분이다.The above-described liquid injectors are being supplied in various ways, such as a manual injector in which a user manually pumps a drug to spray a drug, a power injector using power, and the like, and most of them have only a function of simply dispersing the drug.

한편, 위와 같은 분사기의 문제점을 감안하여 선 출원 공개된 공개번호 제10-2016-0067818호가 개발되었다. 상기 선 출원 발명은 액체가 분사될 때 반작용으로 작용하는 후풍에 의해 회전하는 프로펠러를 설치함으로서 액체 분사과정에서 발생하는 후풍에 의해 프로펠러가 회전하고, 상기 프로펠러가 회전할 때 발생하는 바람이 분사되는 약제에 작용하여 약제의 분사거리와 분사범위를 더 멀리, 더 넓게 분사할 수 있게 하는 취지에서 개발되었던 것이다.On the other hand, in view of the above problems of the injector, Publication No. 10-2016-0067818 published in the prior application was developed. The prior application invention provides a propeller that rotates by the wind that acts as a reaction when the liquid is sprayed, so that the propeller is rotated by the wind generated during the liquid spray process, and the wind generated when the propeller rotates is sprayed. It was developed with the intention of allowing the spraying distance and spraying range of the drug to be sprayed farther and wider by acting on

그러나 상기한 선 출원 공개된 발명은 후풍에 의해 프로펠러가 회전하고, 프로펠러에서 발생되는 바람이 다시 약제에 작용한다는 취지의 개발이기는 하지만 이론적으로 액재 분사시 발생하는 후풍이 프로펠러를 회전시킬 경우 프로펠러에서 발생된 바람이 다시 약제에 작용할 수 없어 사실상 실시 불가능한 발명인 것이고, 더 나아가 선단에 노즐이 방사상으로 구비된 노즐관을 구비한 헤드가 회전될 수 있게 구성한 회전체와, 상기 회전체의 중심에 위치하며 회전할 수 없게 구성된 중심관체 사이에 회전이 자유롭게 이루어지게 하면서도 누수를 예방할 수 있는 밀폐기능이 제대로 구성되지 않아 사용 중 누수가 필연적으로 발생할 수밖에 없는 등의 문제점이 따랐다.However, although the above-mentioned invention disclosed in the prior application is a development to the effect that the propeller rotates due to the tailwind and the wind generated from the propeller acts on the drug again, theoretically, when the tailwind generated during injection of the liquid material rotates the propeller, the propeller generates It is an invention that is practically impossible to implement because the wind cannot act on the medicine again, and furthermore, a rotating body configured to rotate a head having a nozzle tube having a nozzle radially provided at the tip, and a rotating body located at the center of the rotating body Although the rotation between the central tubes configured to be impossible is freely performed, the sealing function to prevent leakage is not properly configured, so leakage inevitably occurs during use.

첨부도면 도1~도2에서 보는 바와 같이 본 발명은, 선단에 대각방향으로 분사되는 노즐(11)을 가진 3~4개의 노즐관(12)이 방사상으로 설치된 헤드(1)와, 선단에 상기 헤드(1)가 결합되고 내부에 베어링과 밀폐용 패킹 등이 내장 설치되어 상기 헤드(1)가 원활하게 회전할 수 있도록 유도하는 회전뭉치(2), 그리고 상기 회전뭉치(2) 후미 외주면에 결합되어 회전뭉치(2)와 함께 회전되면서 분사되는 약제를 더 멀리 더 넓게 날려 보낼 수 있게 하는 프로펠러(3), 그리고 상기 회전뭉치 중심에 설치되는 중심관(4)과 연결되어 약제를 공급하며 후미에 호스가 연결 구성된 자루(41)로 이루어진다.As shown in the accompanying drawings FIGS. 1 and 2, the present invention includes a head 1 having 3 to 4 nozzle tubes 12 radially installed with nozzles 11 spraying in a diagonal direction at the tip, and the head 1 at the tip. The head (1) is coupled, and a bearing and sealing packing are built-in to guide the head (1) to rotate smoothly, and the rotating assembly (2) is coupled to the outer circumferential surface of the rear end of the rotary assembly (2) It is connected to the propeller (3), which is rotated together with the rotating bundle (2) to blow the injected drug farther and wider, and the central tube (4) installed at the center of the rotating bundle to supply the drug and to the rear end of the hose is composed of a shank 41 configured to be connected.

상기 회전뭉치(2)는 본체(2a)와 캡(2b)으로 형성되는데, 본체(2a)는 선단에 밀폐부재(25)와 함께 헤드(1)가 체결 고정되도록 헤드결합부(21)가 구비되고, 내경부(2a') 전후에 한 쌍의 베어링(B)(B')이 설치됨으로써 중심관(4)을 중심으로 회전뭉치(2)가 쏠림이나 흔들림 없이 안정적으로 회전할 수 있게 된다.The rotating bundle 2 is formed of a main body 2a and a cap 2b, and the main body 2a is provided with a head coupling part 21 so that the head 1 is fastened and fixed with a sealing member 25 at the front end. And, by installing a pair of bearings (B) (B') before and after the inner diameter portion (2a'), the rotating assembly (2) can stably rotate around the center tube (4) without tilting or shaking.

또 상기 베어링(B)과 베어링(B') 사이에는 테프론패킹(22)(22')을 설치하는데, 상기 테프론 패킹(22)은 외경이 내경부(2a') 내경과의 사이에 틈이 전혀 없도록 억지끼움 방식으로 삽입 설치하여 본체(2a)와 일체화되게 하고, 내경은 중심관(4) 외경보다 크게 하여 중심관(4)에 닿지 않게 함으로서 회전뭉치(2) 회전시 중심관과의 마찰을 예방하였다.In addition, Teflon packings 22 and 22' are installed between the bearings B and B', and the Teflon packing 22 has no gap between the outer diameter and the inner diameter of the inner diameter portion 2a'. It is inserted and installed in an interference fit method so that it is integrated with the main body (2a), and the inner diameter is larger than the outer diameter of the center tube (4) so that it does not touch the center tube (4). prevented.

또, 테프론패킹(22')은 상기 테프론패킹(22) 측면에 밀착되어 마찰작용하게 하되, 이는 내경이 중심관(4)에 틈이 없이 조립되어 이 부분을 통한 누수발생을 예방하고, 외경은 내경부(2a')의 내경 보다 작게 형성하여 중심관(4)을 중심으로 회전뭉치(2)가 회전할 때 테프론패킹(22)은 회전뭉치(2)와 함께 회전하지만 테프론패킹(22')은 중심관(4)에 고정 설치되어 테프론패킹(22)과 테프론패킹(22')이 맞닿은 면만이 마찰 회전하면서 누수를 차단할 수 있게 하였다.In addition, the Teflon packing 22' is in close contact with the side of the Teflon packing 22 to act as a friction, which prevents leakage through this part because the inner diameter is assembled to the central tube 4 without a gap, and the outer diameter is When the rotary assembly 2 rotates around the central tube 4 by forming smaller than the inner diameter of the inner diameter portion 2a', the Teflon packing 22 rotates with the rotary assembly 2, but the Teflon packing 22' is fixed to the central tube 4 so that only the surface in contact with the Teflon packing 22 and the Teflon packing 22' rotates frictionally to block water leakage.
