The present invention relates to a spraying device for spraying chemical liquid and, more specifically, to a spraying device for spraying chemical liquid, which includes a cyclone forming module to increase a distance and a range of discharged chemical liquid, thereby increasing efficiency of spraying the chemical liquid, and spraying the discharged chemical liquid in a particle form, and thus, efficiency of applying the chemical liquid to crops or soils can be increased. To this end, the spraying device for spraying chemical liquid comprises: a body including an outlet formed on a front end, wherein chemical liquid is discharged through the outlet； an air blowing means disposed in the body and including an air blowing fan rotated by applied power and signals； a chemical liquid transfer means configured to receive chemical liquid from a chemical liquid storage tank in which the chemical liquid is stored and transfer the chemical liquid to the outlet of the body； and a cyclone forming module coupled to the outlet and configured to spread the discharged chemical liquid. The cyclone forming module includes: a coupler coupled to the outlet and including a plurality of holes for discharging the chemical liquid； a discharge pipe disposed to surround the coupler, wherein a width of the discharge pipe gradually widens towards a front end； a plurality of reinforcing ribs configured to connect the coupler with the discharge pipe； a first cyclone forming unit formed between the reinforcing ribs and including a discharge passage through which the air delivered by the air blowing means is discharged； and a second cyclone forming unit formed on an outer portion of the first cyclone forming unit and configured to discharge the air delivered by the air blowing means.COPYRIGHT KIPO 2020본 발명은 약액 살포용 분무장치에 관한 것으로, 보다 상세하게는 배출되는 약액의 거리 및 범위를 확산시키기 위한 싸이클론 형성모듈이 더 구비되어 약액의 살포 효율을 높이며 동시에 배출되는 약액을 입자 형태로 분무화시켜 작물 또는 토양에 착상되는 효율을 높인 약액 살포용 분무장치에 관한 것이다.이를 위해 본 발명은, 전단부에 약액이 배출되는 배출구가 형성
