Description

동력분무기에 있어서 송출구의 자동개폐장치{ The automatic opening and shutting equipment of an outlet pipe on power spray }Automatic opening and shutting equipment of an outlet pipe on power spray}

본 고안은 동력분무기에 있어서 송출구의 자동개폐장치에 관한 것이며 보다 구체적으로는 동력분무기에서 압축되는 약액이 분사되지 않을때에는 약액압축이 자동 중단할 수 있도록 한 것이다.The present invention relates to an automatic opening and closing device of the outlet in the power sprayer, and more specifically, the chemical liquid compression can be automatically stopped when the chemical liquid compressed in the power sprayer is not injected.

일반적으로 동력분무기는 모터나 엔진등의 동력을 전달받아 크랭크에 연결된 플린져나 실린더의 약액을 압축하게 되면 압축된 약액은 유치실에서 축적되면서 송출구를 통하여 약액의 분사가 이루어지게 된다.In general, when the power sprayer receives power from a motor or an engine, and compresses the chemical liquid of the pliner or cylinder connected to the crank, the compressed chemical liquid is accumulated in the detention chamber, and the chemical liquid is injected through the outlet.

이 때 약액의 압축공간에는 안전밸브를 설치하여 약액이 설정압력에 이르면 안전밸브가 열리면서 압축되는 약액을 회수구로 배출시키게 되면서 일정한 압력을 유지하게 된다.At this time, a safety valve is installed in the compression space of the chemical liquid, and when the chemical liquid reaches the set pressure, the safety valve opens and discharges the compressed chemical liquid to the recovery port to maintain a constant pressure.

이와 같은 종래의 동력분무기는 약액의 살포를 중단하게 되더라도 약액의 압축이 계속적으로 이루어지게 되면서 설정압력을 유지하게 하므로 위험하고 엔진 또는 모터에 부하가 발생되어 연료 또는 전력의 소모가 계속되고, 또 동력분무기의 플린져는 약액의 압축을 계속하게 되므로서 플린져와 패킹등 각종의 마찰부품에 마모가 발생하여 사용수명이 감소되는 폐단이 발생하게 된다.The conventional power sprayer is dangerous because it keeps the set pressure while continuing the compression of the chemical even if the spraying of the chemical liquid is stopped, the engine or motor load is generated, the consumption of fuel or power continues, and the power As the plunger of the nebulizer continues to compress the chemical liquid, abrasion occurs in various friction parts such as the plunger and the packing, and a closed end of the service life is reduced.

이를 해소하는 수단으로는 약액압축실에 안전밸브를 설치하여 약액이 압축되어 약액이 송출구를 통하여 분사가 될때에는 약액의 압축이 계속되고 분사가 이루어지지 않을때에는 압력의 상승으로 안전밸브가 압력이 약한 부위로 이동되면서 마이크로 스위치를 동작시켜 전원을 차단, 엔진 또는 모터의 동작을 중단케 하므로서 연료 또는 전력의 소모를 줄이고 동력분무기등의 사용수명을 연장할 수 있도록 구성하게 되나 이와 같은 동력분무기는 약액살포를 일시적으로 중단하게 되더라도 엔진 또는 모터가 정지되므로서 동력분무기가 구동되지 않아 사용이 불편하고 또 모터 또는 엔진의 작동을 중단시키게 하는 마이크로 스위치의 제어수단에는 또 다른 전원이 요구되는 폐단이 있는 실정이다.As a means to solve this problem, a safety valve is installed in the chemical liquid compression chamber so that the chemical liquid is compressed and the chemical liquid continues to be compressed when the chemical liquid is injected through the outlet port. It is configured to reduce the consumption of fuel or electric power and to extend the service life of power sprayers by moving the micro switch and shutting off the power by stopping the operation of the engine or motor while moving to a weak area. Even if the spraying is temporarily stopped, the engine or motor is stopped and the power sprayer is not driven, which makes it inconvenient to use and the control means of the micro switch which causes the motor or the engine to be stopped. to be.

이에 본 고안은 종래의 위와 같은 제반결점을 해소하고 동력분무기에서 압축시키는 약액의 살포가 중단되면 송출공간의 압력이 높아지면서 약액의 송출구는 차단되고 약액을 회수구를 통하게 하여 회수되므로서 송출공간의 약액압축을 해소하여 동력분무기가 공회전(펌핑상태로 유지)되도록 하고 약액을 살포시에는 압축상태로 전환될 수 있도록 하여 엔진 또는 모터 및 동력분무기의 부하를 줄이고 플린져 및 부품마모를 줄이며 더 나아가 연료 및 전력의 소모도 줄일 수 있는 동력분무기에서 송출구의 자동개폐장치를 제공함에 목적이 있다.Therefore, the present invention solves the above-mentioned general defects and stops spraying the chemical liquid compressed by the power sprayer, and the pressure of the discharge space is increased, the discharge port of the chemical liquid is blocked, and the chemical liquid is recovered through the recovery port, By eliminating chemical compression, the power sprayer is idle (pumped) and switched to compressed state when spraying chemicals, reducing the load on the engine or motor and power sprayer, reducing the wear and tear of parts and further fuel and It is an object of the present invention to provide an automatic opening and closing device of an outlet in a power sprayer that can reduce power consumption.

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

통상 동력분무기(1)의 약액 압축몸통(2)의 상부에 자동개폐장치(3)의 입수관(11)을 결합하면 약액송출공간(12)에 구비되는 한쌍의 약액 송출구(15)에는 통상과 같이 약액분사대를 갖는 약액호스를 각 연결하고, 약액회수구(16)에는 약액회수호스를 연결하여 약액탱크로 유입되게 설치하여 사용하게 된다.In general, when the inlet pipe 11 of the automatic opening and closing device 3 is coupled to the upper portion of the chemical liquid compression body 2 of the power sprayer 1, a pair of chemical liquid delivery ports 15 provided in the chemical liquid delivery space 12 are usually provided. As described above, each of the chemical liquid hoses having a chemical spray table is connected, and the chemical liquid recovery hose 16 is connected to the chemical liquid recovery hose to be installed to be introduced into the chemical liquid tank.

즉 엔진 또는 모터를 이용하여 동력분무기(1)를 구동시키게 되면 통상과 같이 크랭크가 구동되고 동 크랭크에 연결된 플린져가 약액을 압축시켜 약액 압축몸통(2)으로 약액이 압축되면 고압으로 조성된 동 약액은 입수관(11)을 통하여 약액송출공간(12)으로 유입되어 밸브몸통(17)을 캡나사(26) 방향으로 이동이 이루어지게 된다.That is, when the power sprayer 1 is driven by using an engine or a motor, the crank is driven as usual, and the plunger connected to the crank compresses the chemical liquid, and when the chemical liquid is compressed by the chemical liquid compression body 2, the copper is formed at high pressure. The chemical liquid is introduced into the chemical liquid delivery space 12 through the water inlet pipe 11 to move the valve body 17 toward the cap screw 26.

이 때 약액은 밸브몸통(17)을 지지하는 스프링(24)의 압력보다 강하게 되므로 스프링(24)은 압축상태가 되고 밸브몸통(17)에 내장된 첵밸브(23)는 스프링(24)의 압력보다 강한 상태에서 기능을 갖게 되므로 밸브몸통(17)은 동작되지 않은 상태에서 함께 이동이 이루어지게 된다.At this time, since the chemical liquid is stronger than the pressure of the spring 24 supporting the valve body 17, the spring 24 is in a compressed state, and the check valve 23 embedded in the valve body 17 is the pressure of the spring 24. The valve body 17 is moved together in a non-operated state because it has a function in a stronger state.

한편 약액회수공간(14)에 위치하는 지지봉(33)은 스프링(35)의 탄력으로 격판(13)의 통공(13a)에 경사부가 닿아 밀봉상태를 유지하게 된다.On the other hand, the support rod 33 located in the chemical recovery space 14 is in contact with the through hole (13a) of the diaphragm 13 by the elasticity of the spring 35 to maintain the sealed state.

이와 같이 약액이 약액송출공간(12)에 위치하는 밸브몸통(17)이 이동되어 한쌍의 약액송출구(15)를 지나 캡나사(26) 방향으로 이동되면 설정된 압축상태가 되므로 약액송출구(15)에 연결된 약액분사대를 이용하여 방제를 수행할 수 있게 된다.Thus, when the chemical liquid is moved in the direction of the cap screw 26 through the pair of chemical liquid delivery port 15 is moved to the valve body 17 located in the chemical liquid delivery space 12, the chemical liquid outlet 15 Control can be carried out using a chemical spray table connected to the

또 약액의 분사를 일시적으로 중단하게 되면 약액송출공간(12)에는 압력이 상승하게 되며 동 압력이 설정압력 이상으로 상승되면 밸브몸통(17)의 입수구(17a)를 통하여 첵밸브(23)의 지지판(21)에 형성된 통수공(21a) 내측에 위치하는 밀봉판(20)을 밀어 스프링(19)이 압축되면 약액은 첵밸브케이스(18)의 통수공(18a)를 통하여 약액은 밸브몸통(17)을 벗어나 캡나사(26)방향으로 유입이 이루어지게 되고 동 밸브몸통(17)은 약액회수공간(14)으로 이동이 이루어지게 된다. 이 때 약액분사대로 약액을 송출시키게 되면 이동이 중단되고, 약액송출이 중단되면 밸브몸통(17)은 이동이 계속되면서 밸브몸통(17)의 입수구(17a)즉 선단이 격판(13)의 통공(13a)에 위치하는 지지봉(33)을 밀어주어 통공(13a)이 열리게 되면서 약액은 약액회수공간(14)으로 유입되어 약액회수구(16)를 통하여 약액탱크로 유입되면서 약액의 압축을 중단하게 되고 약액탱크의 약액은 고압분무기(1)를 거쳐 약액회수공간(14)으로 유입되었다가 약액회수구(16)를 통하여 다시 약액탱크로 이어지는 펌핑상태가 되므로서 약액의 압축을 중단하게 된다.In addition, if the injection of the chemical liquid is temporarily stopped, the pressure increases in the chemical liquid delivery space 12, and when the pressure rises above the set pressure, the support plate of the check valve 23 is provided through the inlet port 17a of the valve body 17. When the spring 19 is compressed by pushing the sealing plate 20 located inside the water passage 21a formed in the water passage 21, the chemical liquid passes through the water passage 18a of the valve valve 18. Inflow is made out of the cap screw 26 direction and the valve body 17 is moved to the chemical recovery space (14). At this time, when the chemical liquid is discharged into the chemical liquid spray, the movement is stopped, and when the chemical liquid is stopped, the valve body 17 continues to move while the inlet port 17a of the valve body 17, that is, the opening of the diaphragm 13 By pushing the support rod 33 located in 13a) is opened through the hole (13a), the chemical liquid is introduced into the chemical liquid recovery space 14 and flows into the chemical liquid tank through the chemical liquid recovery port 16 to stop the compression of the chemical liquid The chemical liquid of the chemical tank is introduced into the chemical liquid recovery space 14 through the high-pressure sprayer 1, and then the compression of the chemical liquid is stopped while being pumped to the chemical liquid tank through the chemical liquid recovery port 16 again.

이로 인하여 동력분무기(1)를 구동시키는 엔진 또는 모터의 부하를 해소하게 되고 동력분무기(1)와 플린져등 압축으로 발생되는 부하가 감소되므로서 장구히 사용할 수 있게 되고 부하로 발생되는 연료 또는 전력의 소모를 줄이게 되는 것이다.As a result, the load of the engine or motor driving the power sprayer 1 is eliminated, and the load generated by compression such as the power sprayer 1 and the plunger is reduced, so that it can be used for a long time and the fuel or power generated by the load It will reduce the consumption of.

이와 같은 본 고안에서 약액의 압력조절은 손잡이(32)의 조임력에 따라서 스프링(35)의 탄성이 변화되어 밸브몸통(17)의 이동압력을 조절할 수 있게 된다.In the present invention as described above, the pressure of the chemical liquid is changed in the elasticity of the spring 35 in accordance with the tightening force of the handle 32 to adjust the moving pressure of the valve body (17).

또 본고안에서 손잡이가이드(30)의 나선(30a)을 자동개폐몸통(10)의 나사(14a)에 조일 때 조임구(30d)에 조임봉(도시없음)을 끼워서 조일수 있게 되고 너트(51)로 조임력을 보강하게 되면 진동에 의해 손잡이가이드(30)가 풀리는 일이 해소된다.In this case, when the screw 30a of the handle guide 30 is tightened to the screw 14a of the automatic opening / closing body 10, a tightening rod (not shown) can be inserted into the tightening hole 30d, and the nut 51 can be tightened. When the tightening force is reinforced, the handle guide 30 is loosened by vibration.

또 본 고안은 사용이 중단되어 약액공급이 중단된 약액송출구(15)의 약액을 다시 송출시켜 사용하게 되면 약액송출공간(12)의 밸브몸통(17) 후부의 압력이 약해지게 되면 밸브몸통(17)은 다시 후퇴되면서 격판(13)의 통공(13a)에 위치하는 지지봉(33)의 경사부가 통공(13a)을 막게 되어 약액회수공간(14)은 차단되고 약액송출공간(12)으로 약액이 유입되고 약액송출공간(12)의 약액송출구(15)가 열려 약액이 송출되어 약액분사대를 통하여 분사되는 과정으로 이어지게 된다.In addition, the present invention is to stop the use of the chemical liquid supply port 15 is stopped supplying the chemical solution again to use the chemical liquid delivery space (12) when the pressure of the valve body (17) rear of the valve body weakens the valve body ( 17 is retracted again while the inclined portion of the support rod 33 positioned in the through hole 13a of the diaphragm 13 blocks the through hole 13a, so that the chemical recovery space 14 is blocked and the chemical liquid is discharged into the chemical delivery space 12. The chemical liquid is discharged and the chemical liquid outlet 15 of the chemical liquid delivery space 12 is opened, leading to the process of chemical liquid being sent out and sprayed through the chemical liquid spraying table.

이와 같은 본 고안은 약액의 압축상태를 일정하게 유지하고 약액을 분사시키지 않을때에는 동력분무기의 압축작업을 해제하게 되므로서 안전하게 되고 엔진 또는 모터의 연료와 전력소모를 줄이고 플린져등 관련부품의 마모를 줄일 수 있게 되는 것이다.The present invention maintains a constant compression state of the chemical liquid and releases the spraying work of the power sprayer when the chemical liquid is not injected, thereby reducing the fuel and power consumption of the engine or motor, and reducing the wear of related parts such as the plunger. It will be reduced.

이상과 같은 본 고안은 동력분무기에서 약액의 압축이 설정지점에 이르면 약액송출공간을 차단하여 동력분무기를 펌핑상태로 전환시켜 약액을 회수구를 통하여 회수하고 약액송출공간의 압력이 떨어지면 지지봉이 약액회수공간의 통로가 닫히게 되므로서 약액 송출공간으로 약액이 압축되어 약액이 송출되므로서 엔진과 모터의 부하를 줄이고 연료와 전력의 소모를 줄이며 또 동력분무기의 부품마모를 줄여 장구히 사용할 수 있게 되고 안전하게 되는 잇점이 있다.The present invention as described above, when the compression of the chemical liquid in the power sprayer reaches the set point, shut off the chemical liquid delivery space to switch the power sprayer to the pumping state to recover the chemical liquid through the recovery port, when the pressure of the chemical liquid delivery space drops the support rod recovery As the passage of the space is closed, the chemical liquid is compressed into the chemical liquid delivery space, and the chemical liquid is discharged, thereby reducing the load on the engine and motor, reducing the consumption of fuel and power, and reducing the wear of the power sprayer, making it possible to use it for a long time. There is an advantage.
