이와 같이 구성된 본 고안의 작용 및 효과는 다음과 같다.The operation and effects of the present invention configured as described above are as follows.
농약용기(1) 내에 구부(43)를 통하여 액상의 농약을 주입한 후 손잡이 (21)를 돌려 개폐구 (20)를 회전시켜서 중공부(20')가 연통되게 한 후 스위치를 온(On)시켜서 농약분무기 내에 설치된 흡입펌프를 작동시키면 흡입펌프의 흡입력에 의해서 흐르는 물이나 고여있는 물에 담겨져 있는 연결 호스(30)를 통해서 들어온 물과 농약 공급 개폐관(2), 중고부(20'), 연결단관(3), 농약 공급량 조절편(6)의 농약 유통공(24)(24') (24'')(24'''), 박킹(7)이 농약 유통공(7'''), 농약유통 조절구(8)의 농약 유통공(8'), 중공 농약 혼합구(10) 및 연결관(12)을 통해서 들어온 농약이 중공농약 혼합구(10)의 하단부 주위에서 혼합되어 농약 공급관(16)을 통하여 압력 조절 탱크(44)에 들어온 후 농약 분사관(27)(27')(27'')에 각각 나착된 농약 혼합단관 (26)과 분사 호스(28)를 통하여 물과 농약의 혼합액이 분사되어 나가게 되는 것인데, 용액상의 농약이나 분말상의 농약(수화재)과 물을 1:1의 비율(예500cc:500cc)로 혼합한 혼합액인 농약이 중공부(20')의 좁은 공간을 통하면서 1차로 혼합이 더 잘 이루어지고 연결 단관(3)의 상협하광 형상의 공간부에서 통과하고 있는 농약의 속도가 완만해지면서 2차로 혼합이 다시 이루어지며, 다시 농약 공급량 조절편(6)의 농약 유통공((24)(24')(24'')(24''')중 하나의 농약 유통공으로만 농약이 통과하게 되는데, 농약 용기(1)에 100cc의 농약이 담겨 있을 경우에는 가장 작은 농약 유통공(24)으로 통과 할 수 있도록 고정공( 23)(23')(23'')(23''')중 두군데의 고정공을 선택해서 고정돌부(8'')(8''')에 삽입시키면 되고, 농약 용기(1)에 200cc의 농약이 담겨 있을 경우에는 농약유통공(24')으로 통과 할 수 있도록 두 군데의 고정공을 선택해서 고정돌부(8'')(8''')에 삽입시키면 되며 이와 같은 방법으로 해서 농약 용기(1)에 들어 있는 농약의 부피가 300cc 또는 400cc일때에 농약 유통공(24'')또는 농약유통공(24''')으로 농약이 통과할 수 있도록 하면 된다.After injecting a liquid pesticide into the pesticide container (1) through the sphere 43, by turning the handle 21 to rotate the opening and closing hole 20 to communicate with the hollow portion 20 'and then turn on the switch (On) When the suction pump installed in the pesticide sprayer is operated, the water and the pesticide supply opening / closing pipe (2), the used part (20 '), and the connection are introduced through the connection hose (30) contained in the flowing water or standing water by the suction power of the suction pump. Pesticide distributor (24) (24 ') (24') (24 '' '), backing (7) are pesticide distributor (7' '') Pesticides introduced through the pesticide distribution hole (8 '), hollow pesticide mixing port (10) and connecting tube (12) of the pesticide distribution control unit (8) is mixed around the lower end of the hollow pesticide mixing port (10) and the pesticide supply pipe ( 16) after entering the pressure control tank 44 through the pesticide mixing pipe (26) and the injection hose (28) attached to the pesticide injection pipe (27) (27 ') (27' ') respectively. Mixed solution Pesticides, which are a mixture of solution-type pesticides or powder-type pesticides (hydration material) and water in a ratio of 1: 1 (eg 500cc: 500cc), pass through the narrow space of the hollow portion 20 '. First, the mixing is better, and the mixing of the pesticides is adjusted again, and the mixing of the pesticides is adjusted again. The pesticide passes through only one pesticide distribution hole ((24) (24 ') (24' ') (24' ''). If the pesticide container (1) contains 100cc of pesticide, the smallest pesticide A fixing hole (8 '') (8 '' 'is selected by selecting two fixing holes from the fixing holes (23), 23', 23 '' and 23 '' 'so as to pass through the distribution hole 24. If the pesticide container (1) contains 200cc of pesticide, select the two fixed holes to pass through the pesticide distribution hole (24 ') Insert into the protrusions 8 '' and 8 '' '. In this way, when the volume of pesticide contained in the pesticide container 1 is 300cc or 400cc, the pesticide distribution hole (24' ') or pesticide distribution hole (24 '' ') allow pesticide to pass through.
따라서 유통로가 적은 농약 유통공(24)(24')(24'')(24''')중 어느 하나의 농약 유통공을 통과하면서 배출 속도가 급속히 빨라 와류의 현상이 일어나면서 3차로 혼합이 잘 이루어지며, 중공 농약 혼합구(10)의 농약 혼합공(10')및 배출구(45)를 통과하여 나온 농약과 연결관(12)으로 들어오는 물이 섞여 와류현상을 일으키면서 혼합이 잘 이루어지면서, 농약 공급관(16)을 통하여 압력조절 탱크(44)로 들어간 다음 농약 분사관(27)(27')(27'')에 연결된 농약 혼합 단관(26)의 혼합편(29)으로 나선형상으로 맴돌아 통과하면서 최종적으로 혼합이 다시 이루어지면서 적절하게 혼합된 상태의 농약이 분사 호스(28)을 통하여 분사되게 되는 것이다.Therefore, the discharge rate is rapidly increased while passing through any one of the pesticide distribution holes 24, 24 ', 24' ', and 24' '', which has a small distribution channel, and the vortex phenomenon occurs. This is done well, the pesticide mixing hole (10 ') of the hollow pesticide mixing hole (10) and the pesticides passing through the outlet 45 and the water coming into the connector (12) is mixed and the mixing is made well Into the pressure regulation tank 44 through the pesticide supply pipe 16 and spirally into the mixing piece 29 of the pesticide mixing end pipe 26 connected to the pesticide injection pipes 27, 27 ', 27 " Finally, the mixing is carried out again while the pesticide in the appropriately mixed state is sprayed through the injection hose 28.
압력 조절 탱크(44)의 압력 조절은 조절변(46)으로 조절하는 것으로서 조절변(46)을 열어 놓으면 압력 조절 탱크(44)의 압력이 떨어지고 조절변(46)을 잠그면 압력 조절 탱크(44)의 압력이 올라가는 작용이 일어나므로 압력 조절 탱크(44)이 압력을 적절히 조절해서 농약을 분사시키면 되고, 압력 조절 탱크(44)의 압력이 떨어지건 안떨어지건 상관없이 농약 공급관(16)으로 공급되는 농약의 양은 항상 일정하므로 압력 조절 탱크(44)의 압력이 떨어질 때는 농약 공급관 (16)으로 공급되는 농약 중에서 일부의 농약이 중공 회수구(41), 호스(42) 및 중공 농약 혼합구(14)를 통하여 되돌아 들어오면서 연결 호스(18)를 통하여 들어온 물과 재차 합쳐 와류를 이루면서 재차 농약 공급관 (16)으로 공급되는 것이다.The pressure control of the pressure control tank 44 is controlled by the control valve 46. When the control valve 46 is opened, the pressure of the pressure control tank 44 drops and when the control valve 46 is locked, the pressure control tank 44 is controlled. Since the pressure rise of the pressure control tank 44 to adjust the pressure appropriately to spray the pesticide, the pressure control tank 44 is supplied to the pesticide supply pipe 16 irrespective of whether the pressure drop or drop Since the amount of pesticide is always constant, when the pressure of the pressure control tank 44 drops, some of the pesticides supplied to the pesticide supply pipe 16 are hollow recovery port 41, hose 42 and hollow pesticide mixing port 14 It is supplied back to the pesticide supply pipe (16) while coming back through the connection hose 18 to form a vortex again with the water introduced through the connection hose (18).
이와 같이 본 고안은 농약 혼합기(47)내의 미소하게 적거나 크게 형성된 다양한 중공부를 통하여 농약이 와류를 일으키면서 혼합이 잘 이루어지게 되고 연결 호스(18)을 통하여 들어온 물과 농약이 다시 합쳐져 와류를 일으키면서 혼합이 양호하게 이루어지며, 농약 혼합 단관 (26)을 통하면서 최종적으로 더 혼합이 되게 함으로써 혼합이 잘 된 양호한 상태로 분사되므로 농약이 분무된 상태가 양호하며, 농약의 오염이 방지되고 경제적이며 인력을 감소시킬 수 있는 실용적인 고안이다.As such, the present invention is well mixed while causing the pesticide to vortex through various hollows formed in a small or large amount in the pesticide mixer 47, and the water and the pesticide introduced through the connecting hose 18 are combined again to cause the vortex. And good mixing, and through the pesticide mixing tube (26) and finally to further mixing, the spraying in a good state of mixing well, so that the spraying of pesticides is good, pollution of the pesticide is prevented and economical It is a practical design that can reduce manpower.
