PROBLEM TO BE SOLVED: To provide a fertilizer distributor capable of highly accurately distributing from a small amount of a fertilizer to a large amount of fertilizer by only adjusting an opening of a shutter part regardless of physical properties of the fertilizer.SOLUTION: A fertilizer distributor includes fertilizer dropping ports 10, 11 and 12 to which the fertilizer drops and fertilizer adjustment ports 20, 21 and 22 opened at least one or more of them so as to switch a communicated state and non-communicated state with respect to the fertilizer dropping ports 10, 11 and 12 according to a turn of a shutter plate E. One or more of the fertilizer dropping ports 10, 11 and 12 and/or the fertilizer adjustment ports 20, 21 and 22 have a shape to be changed so that a width along a radial direction of the shutter plate E is large along the turning direction of the shutter plate E.COPYRIGHT: (C)2013,JPO&INPIT【課題】肥料の物性にかかわらず、シャッタ部の開度調節のみで、微量の肥料から大量の肥料まで高精度に散布することができる肥料散布機を提供する。【解決手段】肥料が落下する肥料落下口10、11、12と、シャッタプレートEの回動に伴って肥料落下口10、11、12に対して連通状態と非連通状態とに切替わるように1個以上開口された肥料調整口20、21、22と、を備え、肥料落下口10、11、12及び/又は肥料調整口20、21、22の1個以上は、シャッタプレートEの径方向に沿う幅がシャッタプレートEの回動方向に沿って大きくなるように変化する形状である。【選択図】図3
