상기 도면에 도시된 바와 같이 본 발명은 비닐하우스 상부에 길이방향으로 레일(60)이 구비되고 상기 레일(60)의 양 끝단에 제1ㆍ2구동축(10, 20)을 구비한다.As shown in the drawing, the present invention is provided with a rail 60 in the longitudinal direction on the upper part of the plastic house, and has first and second drive shafts 10 and 20 at both ends of the rail 60.

또한 상기 제1ㆍ2구동측(10, 20)의 일측에 제1ㆍ2모터(30, 31)를 구비하여 전원인가시 상기 제1ㆍ2구동축(10. 20)을 회전시킨다.Further, the first and second motors 30 and 31 are provided on one side of the first and second driving sides 10 and 20 to rotate the first and second driving shafts 10. 20 when the power is applied.

상기 제1ㆍ2구동축(10, 20)에는 다수개의 제1ㆍ2로울러(11, 21)가 소정간격으로 구비되고 상기 레일(60)위에는 양측이 와이어(40)에 의해 고정된 이송부재(50)들이 구비된다.The first and second drive shafts 10 and 20 are provided with a plurality of first and second rollers 11 and 21 at predetermined intervals, and the transfer member 50 having both sides fixed on the rail 60 by wires 40. Are provided.

상기 제1ㆍ2로울러(11, 21)는 상기 제1ㆍ2구동축(10, 20)에 결합시 원웨이(one way) 베어링(12, 22)을 삽입하여 결합한다.When the first and second rollers 11 and 21 are coupled to the first and second driving shafts 10 and 20, one-way bearings 12 and 22 are inserted into and coupled to each other.

한편 상기 레일(60)은 하부에 와이어 안내홀(60)을 구비하여 상기 와이어(40)가 레일(60)에서 이탈이 되지 않도록 하고 상부에는 상기 이송부재(50)들이 이탈이 되지 않도록 레일(60) 양측에 바퀴안내부재(62)가 구비되어 있다.On the other hand, the rail 60 has a wire guide hole 60 at the bottom so that the wire 40 is not separated from the rail 60 and the rail 60 is not separated from the rail 60 at the top. The wheel guide member 62 is provided at both sides.

또한 상기 레일(60)의 양끝단에는 제1ㆍ2리미트 스위치(13, 23)를 구비하여 상기 이송부재(50)들이 상기 레일(60) 위를 이동시 위치를 판별하여 이를 제어부(80)에 전달한다.In addition, first and second limit switches 13 and 23 are provided at both ends of the rail 60 to determine the position when the transfer members 50 move on the rail 60, and transmit the same to the controller 80. do.

상기 제어부(70)는 상기 제1ㆍ2리미트 스위치(13. 23)의 신호를 받아 제1ㆍ2모터(30, 31)의 동작을 제어하도록 한다.The control unit 70 receives the signal of the first and second limit switches 13.23 to control the operation of the first and second motors 30 and 31.

상기와 같이 구성된 본 발명은 전원이 인가되면 제2모터(31)가 작동하여 제2구동축(20)이 구동되면 제2구동축(20)에 결합된 제2로울러(21)들이 회전을 하게 되는데, 레일(60)상에서 와이어(40)에 결합된 이송부재(50)들은 상기 제2로울러(21)가 회전을 하면서 와이어(40)를 귄취하게 되어 상기 이송부재(50)들은 전진을 하게 된다. 이 때, 소정 콤프에서 압축된 약액은 약액공급호스를 지나 상기 이송부재(50)들에 결합되어 있는 약액분사노즐(70)을 통해 분사된다.According to the present invention configured as described above, when the power is applied, the second motor 31 operates, and when the second driving shaft 20 is driven, the second rollers 21 coupled to the second driving shaft 20 rotate. The transfer members 50 coupled to the wires 40 on the rails 60 twist the wires 40 while the second roller 21 rotates so that the transfer members 50 move forward. At this time, the chemical liquid compressed in the predetermined comb is injected through the chemical liquid injection nozzle 70 is coupled to the transfer member 50 through the chemical liquid supply hose.

한편 상기 제2구동축(20)이 제2모터(31)에 의해 회전하는 동안 상기 제1모터(30)와 제1구동축(10)은 정지되어 있으나 상기 제1구동축(10)에 구비된 제1로울러(11)들은 원웨이(one way) 베어링(12)이 삽입되어 있어 정지된 상기 제1구동축(10)상에서 회전을 하며 와이어(40)가 잘 풀리도록 한다.Meanwhile, the first motor 30 and the first driving shaft 10 are stopped while the second driving shaft 20 is rotated by the second motor 31, but the first driving shaft 10 is provided with the first driving shaft 10. The rollers 11 have a one-way bearing 12 inserted therein to rotate on the stationary first drive shaft 10 and allow the wire 40 to be well loosened.

상기 제2모터(31)의 동작으로 전진을 하는 이송부재(50)들이 소정위치에 다다르면 제2리미트 스위치(23)가 이를 감지하여 제어부(80)에 신호를 보내고 상기 제어부(80)는 제2모터(31)의 작동을 중지하고 제1모터(30)를 작동시켜 제1구동축(10)이 동작되고 상기 제1구동축(10)에 구비된 제1로울러(11)들은 회전을 하면서 와이어(40)를 권취하게 되는데 이 때, 상기 이송부재(50)들은 후진을 하게된다.When the transfer members 50 moving forward by the operation of the second motor 31 reach a predetermined position, the second limit switch 23 detects this and sends a signal to the controller 80, and the controller 80 sends a second signal. The first drive shaft 10 is operated by stopping the operation of the motor 31 and operating the first motor 30, and the first rollers 11 provided on the first drive shaft 10 rotate while the wire 40 is rotated. At this time, the transfer member 50 is reversed.

상기 이송부재(50)들이 상기 제1모터(30)에 의해 후진을 하면서 소정위치에 다다르면 제1리미트 스위치(13)는 이를 감지하여 제어부(80)에 신호를 보내고 상기 제어부(80)는 제1ㆍ2모터(30, 31)의 작동을 중지하여 비닐하우스내의 약액분사를 끝내게 된다.When the transfer members 50 reach the predetermined position while reversing by the first motor 30, the first limit switch 13 detects this and sends a signal to the controller 80, and the controller 80 transmits the signal to the first controller 30. ㆍ 2 motors (30, 31) are stopped and the chemical liquid in the plastic house is finished.

한편 상기 이송부재(50)들이 전/후진시 와이어(40)의 인장에 의해 동시에 움직이지 못하고 순위가 가려지게 되는데 이 때 상기 레일(60)을 먼저 지나온 상기 이송부재(50)는 상기 레일(60) 끝단에서 와이어(40)가 소정 인장력으로 부하가 걸리게 되는데 상기 제1ㆍ2로울러(11, 21)내에 삽입된 원웨이(one way)베어링(12, 22)에 의해 상기 와이어(40)에 소정 인장력이상의 부하가 걸리면 상기 제1ㆍ2베어링(11, 21)은 정지하고 상기 제1ㆍ2구동축(10, 20)만 회전하게 되어 와이어(40)의 인장력에 의한 비닐하우스 파손이나 모터의 과부하로 인한 고장을 방지할 수가 있다.On the other hand, the transfer member 50 is not moved at the same time by the tension of the wire 40 when moving forward / backward, the ranking is obscured at this time, the transfer member 50 passing the rail 60 first is the rail 60 At the end, the wire 40 is loaded with a predetermined tensile force, and the wire 40 is fixed to the wire 40 by one-way bearings 12 and 22 inserted into the first and second rollers 11 and 21. When a load equal to or greater than the tensile force is applied, the first and second bearings 11 and 21 are stopped and only the first and second drive shafts 10 and 20 are rotated so that the plastic house may be damaged due to the tension of the wire 40 or the motor may be overloaded. It is possible to prevent the malfunction caused by.

상술한 바와 같이 본 발명은 두 개의 모터로 다수개의 약액분사노즐이 결합된 이송부재를 유동시켜 약액을 분사하고 일반적으로 모터에 전원을 인가하기 위한 전선을 제거하고 약액을 공급하는 약액공급호스만이 이송부재와 유동되어 구조가 간단하며 잦은 고장이 없어 시공비 및 유지비가 적고 다수개의 이송부재를 한 구동축으로 이동시켜 속도차이에 의한 약액살포의 불균형을 방지할 수 있는 효과가 있다.As described above, the present invention injects a chemical liquid by flowing a transfer member coupled to a plurality of chemical liquid injection nozzles with two motors, and in general, only a chemical liquid supply hose for removing a wire for supplying power to a motor and supplying a chemical liquid Since the structure is simple to flow with the conveying member and there is no frequent trouble, there is little construction cost and maintenance cost, and it is effective to prevent the imbalance of chemical liquid spraying due to the speed difference by moving a plurality of conveying members to one drive shaft.
