The present invention relates to a double type sprayer which is connected to a tractor and sprayed in both directions so that pesticides are sprayed simultaneously in both left and right directions. To this end, the present invention relates to a tractor comprising: a tractor capable of traction； Passing the pesticide attached to the trailer to receive the pesticide； A main coaxial shaft mounted on the center of the trailer and rotated by a pitch shaft； A slave shaft attached to the rear of the trailer at a predetermined interval from the main shaft and rotated by belt connection with the main shaft； A first blowing means mounted in front of the slave shaft so that a first blowing port for blowing out wind is directed to one side of the trailer and generating wind by rotation of the slave shaft to spray the pesticide； A second blowing means mounted on a rear side of the slave shaft so that a second air blowing port for discharging the wind is directed to the other side of the trailer and generating wind by rotation of the slave shaft to spray the pesticide； A plurality of first nozzles mounted in front of the first tuyeres for spraying pesticide； A plurality of second nozzles mounted in front of the second tuyeres for spraying pesticides； A pump sprayer mounted on the trailer and connected to the main coaxial shaft to pump the pesticide contained in the pesticide container to supply the pesticide to the first nozzle and the second nozzle； First direction adjusting means for adjusting the direction of the first tuyere in a vertical direction； And a second direction adjusting means for adjusting the direction of the second tuyeres upward and downward.본 고안은 트랙터에 연결되어 좌우 양측방향으로 농약을 동시에 살포하도록 한 양방향으로 살포하는 더블형 방제기에 관한 것이다.이를 위해, 본 고안은 트랙터의 견인력을 전달받아 주행 가능한 트레일러와； 상기 트레일러에 장착되어 농약이 수용되는 농약통과； 상기 트레일러의 중앙에 장착되어 피티오축에 의해 회전하는 주동축과； 상기 트레일러의 후방에 상기 주동축과 일정한 간격으로 장착되어 상기 주동축과 벨트연결되어 회전하는 종동축과； 바람을 배출하는 제1송풍구가 상기 트레일러의 일측방향을 향하도록 상기 종동축의 전방에 장착되어 상기 종동축의 회전에 의해 바람을 발생시켜 농약을 살
