The present invention relates to 360° uniform spraying of a liquid chemical discharged from a nozzle (9) at the time of short-distance spraying and, more specifically, to 360° uniform spraying of a spraying state through a nozzle by continuously positioning a liquid chemical outlet of a ball at a 100% accurate position and by positioning two spline grooves formed on an outer diameter of a split port at accurate positions. In the related art, in a short-distance spraying state, a liquid chemical outlet of a ball (2) is not accurately positioned at a regulated position, an inlet of a spline groove is also not fixed at the time of assembling, so the position thereof is not regulated, and thus there is a defect that a liquid chemical sprayed from the nozzle is not uniformly sprayed. In the present invention, the same concave portion (a) as a circumference of a connection pipe (7) is formed at a lower end of a rear end portion of a body (1). When the connection pipe (7) comes in close contact with the concave portion (a), a position of a liquid chemical outlet of a ball (2) is continuously positioned at a 100% accurate position, two spline grooves divided by 180° and formed on an outer diameter of a split port (3) are accurately positioned to uniformly distribute a liquid chemical, a press washer (5) is pressed by a non-head bolt (4) to tighten such that there is no leakage in the gap between a Teflon packing (6) and the ball (2), and the split hole (3) is fixed. In the present invention, the liquid chemical discharged from the nozzle (9) is sprayed while turning as in the conventional art, but the liquid chemical discharged from the nozzle (9) is uniformly sprayed by 360° sprayed particles become fine, the turning rate of the liquid chemical is also raised, and an attachment rate of the liquid chemical to the front and rear faces of a plant is raised.COPYRIGHT KIPO 2015본 발명은 근거리 분무 시에 노즐(9)에서 배출되는 약액이 360° 균등 분무가 가능하도록 한 것으로, 더욱 상세하게는 볼의 약액 출구가 항상 100% 정확한 위
