PROBLEM TO BE SOLVED: To provide a soil adhesion preventing tool of rotary tiller effectively preventing adhesion of soil to a rotary driven part such as a rotating shaft, a claw mounting part, plowing claws, etc., rotary driven with the rotating shaft, in order to keep a good rotary plowing performance.SOLUTION: The soil adhesion preventing tool is composed of a cylindrical body 1 covering periphery of the rotating shaft S in a freely rotatable state mounted between adjacent claw mounting parts H wherein a plurality of the claw mounting parts H mounted with plowing claw B are arrayed on the shaft direction of the plowing rotating shaft S of the rotary tiller. The adhesion of soil to the rotary shaft S, claw mounting part H or the plowing claw B is prevented by the floating rotation of the cylindrical body 1 around the rotating shaft S accompanying the rotation of the rotating shaft S.COPYRIGHT: (C)2009,JPO&INPIT【課題】良好なロータリ耕耘性能を維持するために、回転軸、並びに爪取付け部や耕耘爪など、回転軸と共に駆動する回転駆動部への着土を効率的に防止しうるロータリ耕耘機の着土防止具を提供すること。【解決手段】ロータリ耕耘機の耕耘用の回転軸Sの軸方向に列設されて耕耘爪Bを取り付けた複数の爪取付け部Hのうち、隣接する爪取付け部H間に取り付けられ、回転軸Sの周囲を、遊動可能な状態で覆う筒状体1からなる着土防止具である。この筒状体1が、回転軸Sの回転に伴って回転軸Sの周囲を遊動しながら回転することで、回転軸S、爪取付け部H、又は耕耘爪Bへの土塊の付着を防止する。【選択図】図8
