Description

【０００１】
【発明の属する技術分野】
この発明は、引起装置で引起した根菜類を堀起装置で堀起して移送装置で後方上部へ移送中に首揃移送装置、及びタッピング移送装置へと引継ぎ首揃えしながら後方へ移送され、該首揃移送装置の後側の左右両側で外周部を所定量重合させて上下に設けた左・右切断刃で首揃え済み該根菜類の葉部の所定位置が切断され、切断済み藁部は葉移送装置で後方へ移送される技術であり、根菜類収穫機として利用できる。
【０００２】
【従来の技術】
根菜類が、例えば、人参であったとすると、この人参を収穫作業するときは、根菜収穫機の走行車両を圃場の畦部を走行させ、この走行車両の横側に前部から順次設けた引起装置で人参は引起され、堀起装置で掘起され、この堀起された人参は移送装置へと引継ぎされて後方上部へ移送され、この移送途中で首揃移送装置、及びタッピング移送装置へと順次引継ぎされ、この首揃移送装置で移送中に人参が首揃され、該首揃移送装置の後側の左右両側で上下方向同じ位置で、更に外周部に所定隙間を設けた切断刃の外周部で人参の葉部の所定位置が切断され、葉部切断済み人参は下側の移送コンベア上へ落下供給されて、この移送コンベアで移送されて収納箱内へ供給されて一時貯留される。
【０００３】
又、切断済み葉部は前記タッピング装置と、葉移送装置とにより、後方へ移送されて、圃場へ落下排出される。
【０００４】
【発明が解決しようとする課題】
左右両側の切断刃の上下方向位置が、同じ高さ位置であることにより、これら切断刃の組付け、及び取外しのときに危険である。又、この切断刃の外周部に所定隙間を設けていることにより、切断性能が低下したり、葉部を切断する所定位置が正確に切断されないことがあったが、この発明により、これらの問題点を解決しようとするものである。
【０００５】
【課題を解決するための手段】
このために、請求項１記載の発明は、走行車両（２）の一方側の横側に前部から順次根菜類を引起す引起装置（４）と、根菜類を掘起す掘起装置（５）と、掘起した該根菜類を後方上部へ移送する移送装置（２８）と、該移送装置（２８）から根菜類を引継ぎして首揃えしながら後方へ移送する首揃移送装置（３３）及びタッピング移送装置（３４）と、該首揃移送装置（３３）の後側の左右両側に設けられ首揃えした根菜類の葉部の所定位置を切断する左右の切断刃（４５ａ，４５ｂ）からなる葉切断装置（１２）と、該葉切断装置（１２）で切断した葉部を後方へ移送する葉移送装置（３５）とを設け、前記首揃移送装置（３３）を移送装置（２８）の後側で且つ該移送装置（２８）の移送終端部から所定距離下方に設け、該首揃移送装置（３３）の上側に所定間隔を空けて平行状態にタッピング移送装置（３４）を設け、該タッピング移送装置（３４）の移送始端部を前記首揃移送装置（３３）の前後方向略中央部に配置し、該タッピング移送装置（３４）の上側に所定間隔を空けて平行状態に葉移送装置（３５）を設け、該葉移送装置（３５）の移送始端部を前記タッピング移送装置（３４）の移送始端部よりも所定距離後方に配置し、前記葉切断装置（１２）を首揃移送装置（３３）の後側で且つタッピング移送装置（３４）の下方に設け、前記タッピング移送装置（３４）の移送始端部側から数えて１番目の第１テンション軸（５５ａ）と２番目の第２テンション軸（５５ａ２）との間の前後方向の略中央位置に前記葉移送装置（３５）の移送始端部の前軸（５９ａ）を配置し、該前軸（５９ａ）と葉移送装置（３５）の移送始端部側から数えて１番目の第４テンション軸（５８ａ）との間の前後方向の略中央位置に前記第２テンション軸（５５ａ２）を配置し、該第２テンション軸（５５ａ２）とタッピング搬送装置（３４）の移送始端部側から数えて３番目の第３テンション軸（５５ａ３）との間の前後方向の略中央位置に前記第４テンション軸（５８ａ）を配置し、該左右の切断刃（４５ａ，４５ｂ）の外径部を所定量重合させて上下に設けたことを特徴とする根菜類収穫機とした。
【０００６】
【発明の作用】
根菜類を収穫するときは、根菜類収穫機の走行車両（２）を圃場の畦部を走行させ、この走行車両（２）の横側に前部から順次設けた引起装置（４）で根菜類の茎葉が引き起こされ、茎葉を引き起こされた根菜類は堀起装置（５）で堀起され、この掘り起こされた根菜類は移送装置（２８）へと引継ぎされて後方上部へ移送され、この移送途中で首揃移送装置（３３）及びタッピング移送装置（３４）へと順次引継ぎされ、この首揃移送装置（３３）で移送中に根菜類が首揃えされ、該首揃移送装置（３３）の後側の左右両側の左右の切断刃（４５ａ，４５ｂ）の外周部を所定量重合させて、上下に設けたこの左右の切断刃（４５ａ，４５ｂ）で根菜類の葉部の所定位置が切断され、葉部を切断された根菜類は下側の移送コンベア上へ落下供給され、この移送コンベアで移送されて、収納箱内へ供給されて一時貯留される。
【０００７】
又、切断された根菜類の葉部は前記タッピング移送装置（３４）と葉部移送装置（３５）とで後方へ移送されて、圃場へ落下排出される。
【０００８】
【発明の効果】
この発明によれば、葉切断装置（１２）の前側で、根菜類の葉部の挟持力が高まるので、根菜類が上下にずれることを防止でき、葉切断装置（１２）が根菜類の根部を切断することを防止できる。
また、左右の切断刃（４５ａ，４５ｂ）の手前側で下側に設けた該左切断刃（４５ａ）を先に取り外した後に奥側の該右切断刃（４５ｂ）を取り外すことにより、危険の防止ができる。そして、これら左右の切断刃（４５ａ，４５ｂ）の外周部を所定量重合させて設けたことにより、切断性能が向上し、また、葉部の所定位置を正確に切断することができる。
