PURPOSE: A fertilizer sprinkler is provided to open and close a wide discharge hole by a lever operation which is same with normal times in a state in which a driver of a tractor has a seat on a driver's seat. CONSTITUTION: A fertilizer sprinkler includes a pivoting link (50) in the upper side of a rotary plate cover (9). The pivoting link is installed by a hinge so that one side is shorter. A pivoting lever is combined with the leading end of the shorter side of the pivoting link through a control bolt (36). The pivoting lever moves forwards and backwards by a lever which is operated up and down in a driving seat. A control plate which is formed in a bottom plate of a fertilizer storage container and controls an opening and closing of a discharge hole which discharges an organic fertilizer is combined with the end of the longer side of the pivoting link by a connection rod. A control hole which discharges the organic fertilizer is formed in both sides of the control plate. A discharge selection plate which blocks one discharge hole when pivoting to one side is installed in the lower side of the control plate. The discharge selection plate is inserted into an elongated groove which is formed in a bottom plate by a control screw.본 발명은 트랙터에 체결되어 유기질 비료를 살포하는 비료 살포기에서, 비료 배출구를 확장시켜 유기질 비료의 배출이 원활히 이루어지도록 하는 비료 살포기에 관한 것이다.본 발명은 비료살포기의 바닥판에 형성된 배출구멍과 상기 바닥판의 저면에서 레버의 전후조작에 따라 회동하는 조절판에 뚫린 조절구멍을 넓게 하여 유기질 비료가 용이하게 배출되게 하고, 상기 레버의 이동력을 늘리는 회동링크를 통하여 조절판에 연결되게 함으로써 이루어지는 것으로, 레버의 조작거리는 크게 하지 않고도 조절판의 이동거리는 크게 이루어진다.
