PROBLEM TO BE SOLVED: To facilitate change adjustment of application width and to secure a proper application state of particulate material.SOLUTION: A particulate material application device has a constitution that: a riding type traveling vehicle body equipped with a boarding seat 7 is furnished with a pair of right and left tanks 10 and 10 storing a particulate material, feed rolls 20a, 20b, 20c and 20d feeding the particulate material in the tanks 10 and 10 to lower ventilation columns 30 below the right and left tanks 10 and 10, respectively and jet pipes 13 are connected to the ventilation columns 30 and the particulate material conveyed by jet air is applied from disk holes 50 attached to the jet pipes 13. The jet pipes 13 are composed of pipes 13A and extension pipes 13B. The extension pipes 13B are rotated around rotary fulcrums relative to the pipes 13A, and can be changed from a wide width application state extended in a straight line to a standard application state of folded storage, and application guide plates 65 are replaceably arranged at the tip outlet parts of the pipes 13A or the tip outlet parts of the extension pipes 13B.COPYRIGHT: (C)2011,JPO&INPIT【課題】散布幅の変更調整の容易化、粉粒状物の適正散布状態を確保しようとする。【解決手段】搭乗座席7を備えた乗用型走行車体に、粉粒状物を収容する左右一対のタンク10,10を設け、該左右のタンク10,10夫々の下方に、タンク10,10内の粉粒状物を下方の通気筒30に繰り出す繰出ロール20a,20b,20c,20dを設け、該通気筒30に噴管13を接続し、噴風によって搬送される粉粒状物を噴管13に設けた噴口50から散布する粉粒状物散布装置において、前記噴管13を元管13Aと延長管13Bとにより構成し、前記延長管13Bを元管13Aに対して回動支点周りに回動して直線状に延びた広幅散布状態と折畳み収納の標準散布状態に切換可能に設け、前記元管13Aの先端出口部又は延長管13Bの先端出口部に散布案内板65を付替え可能に設ける。【選択図】 図5
