The present invention relates to an agricultural sprayer and a chemical blowing rod for the same. The agricultural sprayer comprises: a blowing device comprising a blowing pipe (15) including a handle (14) at a predetermined position, wherein the blowing device includes a wrapper pipe (11) at a front end and a rechargeable small blower (13), in other words, a rechargeable small air blower including a switch (not drawn) capable of turning on and off power and controlling speed； and a nozzle (22) connected to a flexible tube (21) and installed in the wrapper pipe (11). The blowing device can be carried on a shoulder by a brace (12) on the rear. A connection unit (23) is installed in the rear of the tube (21) so that the agricultural sprayer can be used by being connected to a backpack sprayer or a handcart type sprayer. According to the present invention, when the rechargeable small blower (13) operates when a chemical is sprayed through the nozzle (22), strong wind generated by the rechargeable small blower (13) is discharged toward the wrapper pipe (11) through the blowing pipe (15). The strong wind is applied to the chemical sprayed from the nozzle (22), and the sprayed chemical is instantly atomized. At same time, the agricultural sprayer induces the sprayed chemical to be sprayed widely and distantly by the wind. Therefore, the agricultural sprayer can reduce pest control time and the amount of chemical used. Also, the agricultural sprayer can maximize pest control efficiency by not stressing a plant since the chemical is dispersed as a fog by being atomized.본 발명은 농업용 분무기 및 분무기의 송풍 약대에 관한 것이다.구성에 있어서, 선단에 나팔관(11)이 구비되고 후미에 멜빵(12)에 의해 어깨에 멜 수 있음과 동시에 속도조절 및 전원을 끄고 켤수 있는 스위치(도시하지 않음)가 구비된 충전식 소형송풍기, 즉 충전식 소형브로어(13)가 장착되며 외주면 소정위치에 손잡이(14)가 구비된 송풍관(15)으로 이루어진 송풍장치와, 상기 나팔관(11) 내부에 장착되며 유연한 튜브관(21)이 연결된 노즐(22)로 이루어지며, 상기 튜브관(21)의 후미에 연결구(23)를 구비하여 등짐분무기나 수레형 분무기 등에 연결 사용할 수 있게 함을 특징으로 한다.이와 같이 구성된 본 발명은 노즐(22)을 통해 약제가 분사될 때 충전식 소형브로어(13)를 작동시키면 충전식 소형브로어(13)에서 발생
