Description

동력 분무기의 피스톤 윤활장치{Piston lubrication apparatus for power sprayer}[0001] The present invention relates to a piston lubrication apparatus for a power sprayer,

본 고안은 동력분무기의 실린더 패킹에 분무기로 분사되는 약제일부를 강제 공급하여 순환시킴으로써, 별도의 윤활유(구리스)공급 없이 피스톤 작동을 윤활시키고 실린더 패킹의 마모를 최소화할 수 있게 구성한 동력 분무기의 피스톤 윤활장치에 관한 것이다.
The present invention relates to a piston lubrication system of a power sprayer configured to lubricate a piston operation without any additional lubricant (grease) and to minimize wear of the cylinder packing by forcibly supplying and circulating a part of the agent sprayed on the cylinder packing of the power sprayer ≪ / RTI >

종래의 동력분무기에는 약제를 펌핑하여 작물에 분사할 수 있도록 약제흡입통과 약제배출통 사이에 압축이 구비된 실린더를 배치하여 실린더에 피스톤을 장치하고 피스톤을 왕복운동시켜 약제흡입통의 약제를 실린더 압축실로 흡입하여 약제배출통에 저장한 다음, 약제배출통에 장치한 분무노즐을 통해 작물에 분사할 수 있도록 하기 때문에 실린더에 장치한 패킹과 피스톤 사이의 윤활성을 높이기 위해 윤활작용이 양호한 패킹을 사용하고 있다.In a conventional power sprayer, a cylinder equipped with compression is disposed between the medicine suction-medicines discharge cylinder so as to be pumped to the crop so that the medicine can be pumped to the crop, the piston is mounted on the cylinder, the piston is reciprocated, In order to increase the lubrication between the packing and the piston in the cylinder, it is necessary to use a packing with a good lubrication effect because it is sucked into the cylinder and stored in the chemical discharge cylinder and then sprayed to the crop through the spray nozzle have.

그러나 패킹에 사용된 윤활유가 기름성분이기 때문에 약제에 혼입될 경우, 작물에 피해를 주기 때문에 구리스와 같은 유성 윤활제를 사용할 수 없으므로 분무기의 용수를 이용하는 방법이 개시된바 있다.However, since the lubricating oil used in the packing is an oil component, it is not possible to use an oil-based lubricant such as grease because it is harmful to a crop when it is incorporated into a pharmaceutical agent.

그러나 상기 용수이용 윤활방법은 그랜드패킹 일측에 코일스프링을 장치하여 그랜드패킹을 압축시키고 코일스프링이 장치된 공간에 윤활용수가 유입되게 공간을 확보하고 압축탱크와 연결된 배출구 본체에 용수배출호스를 연결하되, 배출구 본체의 측방에 연결부재를 설치하여 배출되는 용수를 호스로 실린더 본체에 연결하도록 되어 있기 때문에 용수 유입구성이 복잡하게 되는 불편이 있고, 그랜드패킹에 코일스프링의 탄력을 가해 패킹을 긴장시켜야 하므로 장치가 어렵고 제작 비용이 많이 드는 불편이 있었다.
However, in the water-based lubrication method, a coil spring is installed at one side of the gland packing to compress the gland packing, to secure space for lubricating water to flow into the space where the coil spring is installed, and to connect the water discharge hose to the discharge port body connected to the compression tank , The connection member is provided on the side of the discharge port body to connect the discharge water to the cylinder main body by the hose. This makes it inconvenient that the water inflow configuration becomes complicated and the packing must be tensioned by applying the elastic force of the coil spring to the gland packing There was a disadvantage that the apparatus was difficult and the manufacturing cost was high.

본 고안은 상기 불편을 해소하기 위하여 개발된 것이다.
The present invention has been developed in order to solve the above inconvenience.

본 고안은 동력분무기에 설치되는 약제흡입통(1)과, 약제배출통(2) 사이에 압축실(3a)이 형성되는 실린더(3)를 설치하여 피스톤(4)을 장치하고 실린더압축실에서 약제흡입통과 연통하는 통공부와 약제배출통과 연통하는 통공부에 역지밸브(B1)(B2)를 설치하여 약제흡입통(1)에서 약제를 흡입하여 실린더(3)의 압축실(3a)을 통해 약제배출통(2)에 저장하고, 약제배출통(2)의 배출구(2a)에 분사노즐을 장치하여 약제를 분사하며, 약제배출통(2) 상부에 압축탱크(2b)와 압력조정기(2c)를 장치하여 약제배출통(2)에 일정압을 부여하는 동력분무기에 있어서, 실린더(3)의 피스톤삽입부 내주면에 패킹장치실(3b)을 형성하여 패킹(5)을 장치하고 패킹장치실에는 약제배출통(2)에 장치된 압력조정기(2c)의 토출실(2d)과 연결되게 연통관(6)을 설치하여 압력조정기의 토출실에 있는 약제일부가 패킹장치실에 공급되어 윤활작용을 하게 하고, 윤활작용을 한 약제는 패킹장치실에서 회수관(6a)을 통해 약제흡입통으로 회수되게 하여 압력조정기의 토출실에서 패킹장치실을 거쳐 약제 흡입통으로 약제일부가 순환될 수 있게 함으로써, 약제 일부를 이용하여 패킹을 윤활시키도록 한 것이다.
The present invention is characterized in that a cylinder (3) in which a compression chamber (3a) is formed is provided between a medicine suction cylinder (1) provided in a power atomizer and a medicine discharge cylinder (2) (B1) and (B2) are installed in the cylinder bore communicating with the cylinder bore communicating with the cylinder bore communicating with the cylinder bore communicating with the cylinder bore communicating with the cylinder bore through the compression chamber (3a) of the cylinder (3) And the pressure tank 2b and the pressure regulator 2c are disposed on the upper side of the medicine discharge cylinder 2. The compression tank 2b and the pressure regulator 2c are connected to each other through the discharge port 2a of the medicine discharge cylinder 2, And a packing chamber 3b is formed on the inner circumferential surface of the piston insertion portion of the cylinder 3 so as to form a packing 5, A communication pipe 6 is provided so as to be connected to the discharge chamber 2d of the pressure regulator 2c provided in the medicine discharge cylinder 2 and is provided in the discharge chamber of the pressure regulator A part of the medicament is supplied to the packing apparatus chamber to lubricate the medicament and the lubricating agent is recovered to the medicine suction cylinder through the return pipe 6a in the packing apparatus chamber and discharged from the discharge chamber of the pressure regulator through the packing apparatus chamber, A portion of the medicine can be circulated in the suction cylinder, thereby lubricating the packing using a part of the medicine.

이와 같이 된 본 고안은 동력분무기가 작동하면 실린더(3)에 장치된 피스톤(4)이 왕복운동하여 악제흡입통의 약제를 실린더 압축실(3a)로 흡인하고 약제배출통(2)으로 송출시켜 저장하며, 약제배출통(2)에 약제가 충만되면 배출구(2a)에 장치된 분사노즐을 개방하여 약제를 작물에 분사할 수 있게 되는데 약제배출통(2)에는 압축탱크(2b)와 압력조정기(2c)가 장치되어 약제배출통(2)의 약제가 일정압력을 유지하게 하여 노즐로 공급되게 하고, 압력조정기의 토출실에 일정압이 작용하게 된다.When the power sprayer is operated, the piston 4 installed in the cylinder 3 reciprocates to suck the medicine in the malodor suction cylinder into the cylinder compression chamber 3a and send it to the medicine discharge cylinder 2 When the medicine is filled in the medicine discharge cylinder 2, the injection nozzle provided in the discharge port 2a is opened to inject the medicine to the crop. In the medicine discharge cylinder 2, a compression tank 2b and a pressure regulator (2c) is installed to allow the medicine in the medicine discharge cylinder (2) to be supplied to the nozzle while maintaining a constant pressure, and a certain pressure acts on the discharge chamber of the pressure regulator.

따라서 토출실과 패킹장치실의 패킹사이에 연결된 연통관(6)에는 일정압을 가진 약제가 공급되게 되는데 본 고안의 패킹(5)은 중앙지지링(501)이 금속제로 되어 그 외주면과 내주면에 환상요입홈(502)(503)이 형성되어 있고, 환상요입호(502)(503)은 연통구멍(504)으로 연통되어 있기 때문에 중앙지지링(501) 양측면에 배치된 패킹링(505)(506)에는 약제배출통과 연통된 압력조정기의 토출실을 통해 공급된 약제가 패킹링을 윤활시키게 되며, 패킹링은 또 외측면에 금속제지지링(507)(508)이 배치되어 일정한 체적을 유지하기 때문에 패킹링에 가해지는 약제가 금속제 지지링 사이에서 패킹링에 공급되므로 패킹링이 일정압을 보유하고 피스톤 표면에 접촉하게 되어 피스톤과 패킹링과의 윤활성을 높이고 밀착력을 강하게 하므로 누출을 방지하면서 패킹링의 마모도 줄 일 수 있게 되므로 패킹의 수명을 내구적으로 유지하게 되는 효과를 얻게 되는 것이다.Therefore, a medicine having a predetermined pressure is supplied to the communication tube 6 connected between the discharge chamber and the packing of the packing chamber. The packing 5 of the present invention has a central support ring 501 made of metal, Since the annular grooves 502 and 503 are formed and the annular grooves 502 and 503 are communicated with the communicating hole 504, the packing rings 505 and 506 disposed on both sides of the central support ring 501, The medicine supplied through the discharging chamber of the pressure regulator communicated with the medicine discharge communication lubricates the packing ring and the packing ring is also provided with the metal supporting rings 507 and 508 on the outer side to maintain a constant volume, Since the chemical applied to the ring is supplied to the packing ring between the metal supporting rings, the packing ring holds a certain pressure and comes into contact with the surface of the piston, thereby increasing the lubricity between the piston and the packing ring and enhancing the adhesive force. Wear Because one will be able to get the effect of the quadrature remain within the life of the packing.

한편, 압력조정기의 토출실에서 공급되는 약제는 2~3kg/㎠ 의 압력을 보유하고 있으므로 패킹장치실에 일정한 압력으로 약제를 공급하여 안정적인 공급이 이루어지며, 또한 각 피스톤장치실은 연통공(3d)으로 서로 연통되어 있어서 연통관(6)으로 공급된 약제가 피스톤장치실을 차례로 통과하여 회수관(6a)을 통해 약제흡입통(1)으로 들어가는 순환이 이루어져 분무기가 작동하는 동안에 지속적인 약제공급과 순환이 이루어지게 되며, 패킹(5)의 패킹링에 공급되는 윤활액은 중앙지지링(501)의 외주면에 형성된 환상요입홈을 통해 연통구멍으로 유입되어 내주면에 형성된 환상요입홈을 통해 패킹링에 전달되므로 윤활액 공급로를 확보하기 위한 별도의 스프링장치가 필요 없게 되는 간편함이 있다.On the other hand, since the medicine supplied from the discharge chamber of the pressure regulator has a pressure of 2 to 3 kg / cm < 2 >, the medicine is supplied at a constant pressure to the packing chamber, So that the medicine supplied to the communicating tube 6 sequentially passes through the piston apparatus chamber and enters the medicine suction cylinder 1 through the return pipe 6a to continuously supply and circulate the medicine while the sprayer is operating And the lubricant supplied to the packing ring of the packing 5 flows into the communication hole through the annular groove formed in the outer peripheral surface of the central support ring 501 and is transmitted to the packing ring through the annular groove formed in the inner peripheral surface, There is no need for a separate spring device for securing the supply path.

그리고 피스톤장치실에 공급되는 윤활제는 분무기로 분사되는 약제의 일부가 공급되므로 피스톤장치실을 통과해서 약제흡입통에 다시들어가서 순환된다해도 작물에 피해를 주지 않게 되어 부작용이 없게 되는 이점을 얻을 수 있고, 이로인해 안전하고 원활한 피스톤윤활이 달성되는 이점이 있다.
Since the lubricant supplied to the piston device chamber is supplied with a part of the medicine sprayed by the sprayer, even if the lubricant is recirculated through the piston device chamber to the medicine suction chamber and circulated, there is no harm to the crop and there is no side effect , Which has the advantage that safe and smooth piston lubrication is achieved.
