Description
したがって、この変換体勢とした時にも、耕深調節体(28)と前出の耕耘爪群の先端回転軌跡(24a)との相対位置関係は変わらず、耕深調節体(28)の底板(29)が食い込み気味に進行し走行抵抗付与力が大になって、機体ダッシングの抑止もが効果的に果されることとなる。
したがって、支点軸(39)に回動自在に装された均平板(40)が軸芯(P)を中心として左右に揺動せんとする際に、開口孔(43)の存在によって均平板(40)と均平板支持基体(36)との干渉が避けられて均平板(40)の左右揺動は難なく行われる。

- ロータリ耕耘装置(15)に装設する均平板(40)の左右方向中央部をロータリ耕耘装置(15)側に設けた前後向き支点軸(39)に回動自在に枢支して均平板(40)が前後向きの軸芯(P)中心で左右に揺動し得るように成し、該均平板(40)とロータリ耕耘装置(15)側とに跨って架装する弾性材(44)を用いた姿勢維持機構(45)を設けて、姿勢維持機構(45)により均平板(40)が水平な常態姿勢に復帰付勢されると共に均平板(40)の左右揺動が設定範囲内で行われるようにしたロータリ耕耘装置の耕土均平装置において、上記の前後向きの支点軸(39)を、ロータリ耕耘装置(15)側に設けられた耕深調節体(28)に着脱自在又は一体的に連設する均平板支持基体(36)に設けてあることを特徴とするロ―タリ耕耘装置の耕土均平装置。
- ロータリ耕耘装置側の耕深調節体(28)に設置する均平板支持基体(36)を前記耕深調節体(28)に沿って上下方向に位置調節自在な鞘状体に形成し、この均平板支持基体(36)から後方に前後向き支点軸(39)を延出させ、該支点軸(39)に均平板(40)の後面側に支持されている取付筒(42)を回動自在に嵌装して均平板(40)を左右揺動自在に支持し、前記取付筒(42)よりも上位で均平板支持基体(36)の後面部に設けた延出部(46)と、その延出部(46)の左右方向横側部において均平板(40)の後面側に対設した延出部(48)とに跨って姿勢維持機構(45)の弾性材(44)を架装したことを特徴とする請求項1に記載されたロータリ耕耘装置の耕土均平装置。
