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. |
