PROBLEM TO BE SOLVED: To make a transfer defect easily avoidable while transferring granular bodies to a supply part by granular body transferring air by distributively supplying the granular body transferring air from a blower to a granular body send-out part in each of a plurality of payout mechanisms.SOLUTION: A biforked part 42a is arranged at a distribution supply pipe 43 which distributes and supplies granular body transfer air to a granular body send-out part 38 of each of a plurality of payout mechanisms 31, and at an air duct 42 which sends the granular body transfer air from a blower 32 into the distribution supply pipe 43. A left discharge port 42b possessed by the biforked part 42a is connected between the payout mechanism 31c at the lateral center side of a traveling machine body out of the distribution supply pipe 43 and a region in which the left-side payout mechanism 31a and the granular body send-out part 38 are connected to each other. A right discharge port 42c possessed by the biforked part 42a is connected between the payout mechanism 31c at the lateral center side of the traveling machine body out of the distribution supply pipe 43 and a region in which the right-side payout mechanism 31b and the granular body send-out part 38 are connected to each other.COPYRIGHT: (C)2014,JPO&INPIT【課題】複数の繰出機構における粉粒体送出部にブロワからの粉粒体搬送風を分配供給して、供給部に粉粒体を粉粒体搬送風によって搬送できながら、搬送不良を回避し易くする。【解決手段】複数の繰出機構31の粉粒体送出部38に粉粒体搬送風を分配供給する分配供給管43、分配供給管43にブロワ32からの粉粒体搬送風を送り込む送風管42に二股部42aを設けてある。二股部42aが備える左の吐出口42bを、分配供給管43のうち、走行機体横中央寄りの繰出機構31cと、左側の繰出機構31aとの粉粒体送出部38が接続している部位の間に接続してある。二股部42aが備える右の吐出口42cを、分配供給管43のうち、走行機体横中央寄りの繰出機構31cと、右側の繰出機構31bとの粉粒体送出部38が接続している部位の間に接続してある。【選択図】図5
