PROBLEM TO BE SOLVED: To bring correspondence to various plant conditions, difference of ridge widths depending on regions and the like to be easily performed.SOLUTION: A ridging fertilizer applicator in which a tilling rotary 6 and a ridge-forming device 7 for forming ridges by accepting tilled soil are installed to a vehicle body 1, a pair of disks 25, 25 corresponding to an interval of the ridge width of a ridge formed by the ridge-forming device 7 are arranged to a tilling shaft 15 of the tilling rotary 6, a delivery device for delivering a granular powder material is installed between the facing disks 25, 25 and the granular powder material delivered between the facing disks 25, 25 is agitated with soil is provided. In the applicator, a cylindrical member 26 in which claw holders 29, 29 for removably mounting tilling claws 23, 23... and disk holders 28, 28 for removably mounting the disks 25, 25 are integrally installed to be slidable to the tilling-claw shaft 15 and to be fixable to a predetermined site. In addition, a tool bar 33 is installed to a tilling frame 31 of the tilling rotary 6 and the ridge-forming device 7 is installed to the tool bar 33 to be freely adjustable to lateral positions.COPYRIGHT: (C)2010,JPO&INPIT【課題】 各種作物条件や地域による畝幅の相違等への対応の容易化を図る。【解決手段】 車体1に耕耘ロータリ6と耕耘土壌を受けて畝成形する畝成形器7を装着し、耕耘ロータリ6の耕耘軸15には畝成形器7で成形する畝の畝幅間で対応する対のディスク25,25を配設し、該ディスク25,25間に粉粒状物を繰り出す繰出装置を設け、対向するディスク25,25間において繰り出された粉粒状物を土壌と共に攪拌する畝立施肥装置において、前記耕耘爪23,23…を着脱自在に装着する爪ホルダ29,29とディスク25,25を着脱自在に装着するディスクホルダ28,28とを一体的に設けた筒状部材26を耕耘爪軸15に対してスライド自在でかつ所定位置に固定可能に設ける。また、耕耘ロータリ6の耕耘フレーム31にツールバー33を設け、該ツールバー33に畝成形器7を左右位置調整自在に設ける。【選択図】 図3
