PROBLEM TO BE SOLVED: To provide a fertilizer distributor which has no risk that fertilizer is clogged inside a fertilizer discharge passage and discharge operation is interrupted.SOLUTION: A fertilizer distributer is provided with a fertilizer delivery part 68 for feeding the fertilizer which falls to a lower part of a fertilizer tank 67 that stores fertilizer. A fertilizer application hose 62 which transports the fertilizer toward a farm field is provided thereunder. A conveyance air duct 33 through which fertilizer conveyance air passes and a blower 69 are provided below the fertilizer tank 67. The fertilizer distributer is further provided with a delivery roll 45 that feeds the fertilizer by a fixed quantity to the fertilizer delivery part 68, and a switching shatter 47 that switches a fertilizer blow-off passage 34 provided adjacent to the delivery roll 45, between a fertilizer application duct 34b and a fertilizer discharge duct 34a for discharging the fertilizer to the outside of the machine. The fertilizer distributer is also provided with a flow-down case 46 that houses the fertilizer delivery part 68 and the switching shatter 47. At the time of switching fertilizer feed between the fertilizer application duct 34b and the fertilizer discharge duct 34a, the switching shatter 47 can switch the fertilizer blow-off passage 34 through a cut-off position, where the fertilizer conveyance air is not moved to either the side of the fertilizer application duct 34b or the side of the fertilizer discharge duct 34a.COPYRIGHT: (C)2014,JPO&INPIT【課題】肥料排出通路内に肥料が詰まり、排出作業が中断されてしまうおそれのない施肥機を提供すること。【解決手段】 肥料を貯留する肥料タンク67下部に落下する肥料を送り出す肥料繰出部68、その下方に肥料を圃場に向けて搬送する施肥ホース62を設け、肥料タンク67の下方に肥料の搬送風が移動する搬送風ダクト33とブロア69とを備え、肥料繰出部68に肥料を定量ずつ送り出す繰出しロール45とその隣接位置に設けた肥料の放出経路34を施肥ダクト34bと機外に肥料を排出する機外排出ダクト34aに切り替える切替シャッタ47を設け、肥料繰出部68と切替シャッタ47を内装する流下ケース46を設け、切替シャッタ47は、施肥ダクト34bと機外排出ダクト34aの肥料供給切替の際に、施肥ダクト34b側にも機外排出ダクト34a側にも搬送風を移動させない遮断位置を経由して肥料の放出経路34を切り替えることができる施肥機である。【選択図】図4
