The present invention relates to a sprayer for spraying and controlling pesticides. The sprayer head 1 having two to four nozzles 11 and a nozzle stand 12 is mounted on the tip of a bag-shaped bag 2 having a handle 22 and a valve 21 The rotary device 3 is provided with a bearing 31 and an O-ring 32 in the support 3b together with a connecting rod 3a, a support 3b and a rotary cap 3c. And a rotating body 3d which is installed so as to be freely rotatable by the rotating cap 3c and which is coupled to the inside of the rotating cap 3c and rotates together with the rotating cap 3c and has a water hole 33 at the center, The rotary cap 3c and the rotary body 3d can be disassembled and assembled and the rotary vane 4 is mounted on the rotary cap 3c so as to react with the injector head 1) rotates, the rotary vane (4) rotates together with the medicinal material when it is sprayed in the form of a whirl, so that the sprayed medicament is spread widely, And the like. In the present invention constructed as described above, the reaction generated when the medicinal material is injected and the injector head 1 and the rotary vane 4 are rotated at a higher speed by the screw 35 mounted inside the rotating body 3d, It is possible to maximize the disaster prevention efficiency. Further, safety of the operator is ensured by the safety cover 5, and in the case of the umbrella type safety cover 5 ', the folding is easy, The volume is minimized, so that the portable device can be easily carried, stored, and stored. Therefore, when the device is used, it is possible to protect the user from the medicinal drug, thereby maximizing the reliability.본 발명은 농약 살포 및 방제용 분사기에 관한 것이다.구성을 살펴보면, 손잡이(22)와 밸브(21)가 구비된 파이프 형태의 자루(2) 선단에 2~4개의 노즐(11) 및 노즐대(12)가 구비된 분사기 헤드(1)를 장착한 회전장치(3)를 설치하되, 상기 회전장치(3)는 연결대(3a)와 지지체(3b), 회전캡(3c)과 함께 상기 지지체(3b) 내부에 베어링(31)과 오링(32)에 의해 자유롭게 회전되도록 설치됨과 동시에 선단이 회전캡(3c) 내부에 체결되어 회전캡(3c)과 함께 회전되며 중앙부에 통수공(33)이 구비된 회전체(3d)로 이루어져 연결대(3a), 지지체(3b), 회전캡(3c), 회전체(3d)가 분해조
