Description

【０００１】
【発明の属する技術分野】
本発明は、たとえば、玉葱、馬鈴薯、薩摩芋等の農産物を掘り取る掘取機に関する。
【０００２】
【従来の技術】
従来、この種の掘取機としては、たとえば、実用新案登録第２５９０４８６号公報に記載された構成が知られている。この公報に記載された構成は、農産物を掘り取る農産物掘取体を設け、この農産物掘取体にて掘り取られた農産物を土をふるい落としながら往路側搬送面で搬送する無端回行体を有するコンベヤを設け、このコンベヤの往路側搬送面から農産物の掘り取り後の畝上に農産物を搬出する構成となっている。
【０００３】
【発明が解決しようとする課題】
前記公報に記載された構成では、コンベヤの往路側搬送面から農産物の掘り取り後の畝の表面上に農産物を搬出するとき、この畝の表面上からこの畝溝やこの畝に隣接する畝側に農産物が転がり落ち易く、トラクタにて農産物の拾い上げ作業機を牽引して畝の表面上の農産物を拾い上げるとき、畝の表面上から転がり落ちた農産物を拾い上げることができず、トラクタのタイヤで農産物を踏み付けることがある、という問題がある。
【０００４】
そこで、コンベヤの後方に位置して畝幅の両側に畝上に農産物を案内する案内側板を配置することが考えられるが、この構成では案内側板にて畝上に搬出された農産物が上下に重なり合った状態となったとき、この案内側板が通過することにより、畝溝やこの畝に隣接する畝側に下側の農産物上から上側の農産物が転がり落ち易く、また、下側の農産物上から上側の農産物が畝の幅方向中央側に転がり落ちるとき、この上側の農産物にて下側の農産物を畝溝側に押動しこの下側の農産物を畝溝に転がり落すおそれもある、という問題がある。
【０００５】
本発明は、このような点に鑑みてなされたもので、コンベヤの往路側搬送面から農産物の掘り取り後の畝上に搬出される農産物が畝溝やこの畝に隣接する畝側に転がり落ちることを確実に防止でき、農産物掘取体にて掘り取られた農産物を確実に拾い上げることができる状態に畝上に農産物を確実に集めることができ、農産物の地干し効果を向上できる掘取機を提供することを目的とするものである。
【０００６】
【課題を解決するための手段】
請求項１記載の掘取機は、農産物を掘り取る農産物掘取体と、この農産物掘取体にて掘り取られた農産物を土をふるい落としながら往路側搬送面で搬送する無端回行体を有するコンベヤとを備え、このコンベヤの往路側搬送面から農産物の掘り取り後の畝上に農産物を搬出する掘取機において、前記コンベヤの後方に位置して配設され、農産物の掘り取り後の畝幅の両側でそれぞれ畝上に搬出された農産物を畝上に保持させる農産物保持部と、この両側の農産物保持部の上方に位置しかつ前記コンベヤの後方に位置してそれぞれ配設され、この農産物保持部にて畝上に保持された農産物上に落下する農産物を畝の幅方向中央側に向けて案内する農産物案内部と、農産物の掘り取り後の畝中央部で畝上に搬出される農産物を両側に振り分ける断面略山形状の振分体とを備え、前記両側の農産物保持部は、リンク機構にて畝の高さに応じてそれぞれ上下動可能に設けられているものである。
【０００７】
そして、農産物掘取体にて農産物が順次掘り取られるとともに、この農産物掘取体からコンベヤの無端回行体の往路側搬送面上に農産物が順次搬入され、この往路側搬送面にて農産物が土をふるい落としながら順次搬出部に向かって搬送され、この往路側搬送面から農産物の掘り取り後の畝上に農産物が順次搬出される。
【０００８】
また、農産物の掘り取り後の畝幅の両側に配設された農産物保持部にて往路側搬送面から畝上に搬出された農産物が畝上に順次保持され、これらの農産物が畝溝に落下することを防止される。
【０００９】
また、農産物保持部にて畝上に保持された農産物上に落下する農産物が農産物保持部の上方に位置して配設された農産物案内部にて畝の幅方向中央側に向けて案内され、これら農産物が畝の幅方向中央側の畝上に落下される。したがって、これらの農産物が畝幅の両側で上下に重なり合うことを防止される。
【００１０】
また、農産物保持部にて保持された農産物上から畝の幅方向中央側の畝の表面上に農産物が落下するとき、この農産物にて畝上に保持された農産物が畝溝側に向かって押動されることがあっても、この押動される農産物が農産物保持部にて畝上に保持されているため、この農産物が畝溝に落下されることを確実に防止される。
【００１１】
したがって、農産物掘取体にて掘り取られた農産物を確実に拾い上げることができる状態に畝上に農産物を確実に集めることができ、これらの農産物の地干し効果を向上できる。
【００１２】
また、畝の高さが変化しても、その畝の高さに応じて農産物保持部が上下動して進行し、この農産物保持部にて畝上に農産物が確実に保持され、この農産物が畝溝に落下することを確実に防止される。
【００１３】
請求項２記載の掘取機は、請求項１記載の掘取機において、農産物保持部は、掘取機の進行方向に長手方向を有し上下に並設した棒状部材にて形成したものである。
【００１４】
そして、上下に並設した棒状部材にて掘取機の進行方向に長手方向を有した保持部が形成され、この棒状部材の長手方向の保持部が進行しながらこの保持部にて畝の表面上に農産物が保持され、この農産物が畝溝に落下することを更に確実に防止される。
【００１５】

【００２３】
そして、前記農産物掘取体３の前記掘取刃25にて掘り取られた農産物Ａがこの掘取刃25から前記コンベヤ６の無端回行体５の往路側搬送面４に搬入されるようになっている。
【００２４】
なお、前記掘取刃25の後端部と前記往路側搬送面４の掘取刃25側の上面との間には、前記掘取刃25から前記往路側搬送面４上に土をなるべく送り込まないように前記往路側搬送面４の掘取刃25側を高くして多少の段差と隙間が形成されている。そして、前記往路側搬送面４の掘取刃25側の面で土を砕き隙間から畝Ｂに落下するようになっている。
【００２５】
つぎに、前記コンベヤ６は、図１及び図２に示すように、前記掘取刃25の後方に位置して前記主フレーム11の両端部に固定された前記側板12の前側下端部にそれぞれ支軸27にて回転自在に軸支された従動輪28と、これら従動輪28に対向して駆動輪29をそれぞれ両端部に固定し前記側板12の後端側上部に回転自在に軸支された駆動軸30と、前記従動輪28と前記駆動輪29との間に掛け回された前記無端回行体５とを有している。
【００２６】
そして、前記無端回行体５は、図２に示すように、前記前後の従動輪28と駆動輪29との間にそれぞれ掛け回すように両端部に相対して配置されリンクプレートを連繋した無端帯31と、これら無端帯31間に農産物Ａを搬送し土をふるい落とす間隔をおいて回転可能に並設軸架されて搬送杆32とを有している。
【００２７】
また、前記従動輪28にて折返される前記無端回行体５の折返部と前記掘取刃25の後端部との間には土のみをふるい落とす間隙が形成されている。そして、掘取刃25から農産物Ａが前記無端回行体５の往路側搬送面４に搬入されるようになっている。
【００２８】
また、前記無端回行体５において、前記従動輪28と前記駆動輪29との間で前記従動輪28にて折返されて前記駆動輪29に向かって移動する側が前記往路側搬送面４となっている。
【００２９】
つぎに、図１及び図２に示すように、前記一方側の側板12に前後方向に長手方向を有した伝動ケース33が固定され、この伝動ケース33の前端部内に前記出力軸22の外端部が回転自在に突出され、この出力軸22の外端部にプーリ34が固定されている。

【００３１】
つぎに、前記接地体７は、図１及び図３に示すように、前記掘取機１の進行方向に長手方向を有したそり体37にて形成されている。前記そり体37の前端部が前記両側板12の下端部に支軸38にてそれぞれ回動可能に軸支され、これらそり体37の後端側上に支軸39にて支柱40の下端部がそれぞれ回動自在に軸支され、これら支柱40が前記両側板12に固定されたホルダー41内に上下方向に位置調節可能に挿通されている。そして、これら支柱40の所定の位置が前記ホルダー41に連結ピン42にて連結されて支持されている。
【００３２】
つぎに、前記コンベヤ６の後方に位置して農産物Ａの掘り取り後の畝Ａ上に農産物Ａを案内する案内体43が設けられている。この案内体43は、図１及び図２に示すように、前記畝Ｂ幅の両側にそれぞれ配置した案内側板46と、これら案内側板46の後端部間に固定された後側案内板47と、この後側案内板47の中間部の下端に水平状に配置され前後方向に長手方向を有した振分体48とを有している。
【００３３】
前記両側の案内側板46は、図２及び図４に示すように、前記掘取機１の進行方向に向かって拡開して傾斜した状態で略垂直状に配置され、この両側の案内側板46は、これら案内側板46から前方に向かって突出された支持アーム45にて前記両側板12の後端側にそれぞれ支持されている。
【００３４】
前記後側案内板47は、図２に示すように、前記両側の案内側板46の後端部間に下端側が前記コンベヤ６側に向かって突出するように傾斜した状態で固定されている。また、前記案内側板46と前記後側案内板47との内面にはゴム板等の緩衝材49が配設され、この緩衝材49は前記案内側板46と前記後側案内板47との内面に固着されている。
【００３５】
そして、前記畝Ｂ幅の両側にそれぞれ配置した案内側板46とこれら案内側板46の後端部間に固定された後側案内板47とにより後側案内板47の中間部の下端に前記振分体48を配置した案内体43が前記コンベヤ６の農産物搬出側を開口した平面視略コ字形状に形成されている。
【００３６】
また、前記振分体48は、図２に示すように、前記両側板12の後端側の下端部間に設けた振分体支持機構50にて支持されている。前記振分体支持機構50は、左右方向に長手方向を有した支持枠51と、この支持枠51の中間部に後方に向かって突出固定された支持突部52とを有している。
【００３７】

【００３９】
つぎに、前記両側の農産物保持部８は、前記案内体43の両側の案内側板46の下方に位置してリンク機構44にて前記そり体37を支持した支柱40に畝Ｂの高さに応じてそれぞれ上下動可能に設けられている。そして、前記両側の農産物保持部８は、図１乃至図３に示すように、掘取機１の進行方向に長手方向を有し上下に並設した棒状部材55にてそれぞれ形成されている。
【００４０】
また、前記両側の棒状部材55は、上下に所定の間隔をおいて複数本が並設され、これらの棒状部材55のうち、上端部の棒状部材55がこの上端部の棒状部材55より下側の棒状部材55より畝の幅方向中央側に突出した状態に配置されている。そして、これら上下の棒状部材55にて農産物Ａの掘り取り後の畝Ｂ幅の両側でそれぞれ畝Ｂ上に搬出された農産物Ａを畝Ｂ上に保持させるようになっている。
【００４１】
また、前記各棒状部材55の一端部が可動枠56にそれぞれ固定されている。この可動枠56は、相対する側板部57を有して平面視コ字形状に形成され、この可動枠56の側板部57に前記各棒状部材55の一端部がそれぞれ固定されている。そして、前記各棒状部材55は丸棒にてそれぞれ形成され、これら各棒状部材55の周面は農産物Ａに対する衝撃を緩衝する緩衝材にて被覆されている。
【００４２】
また、前記支柱40に固定枠58が固定されている。この固定枠58は前記支柱40に固定された矩形状の固定板59と、この固定板59の後端側の上下にそれぞれ固定され左右方向に長手方向を有した中空筒状の軸支体60と、これら上下の軸支体60にそれぞれ挿通された支軸61とを有している。
【００４３】
そして、前記固定枠58に前記リンク機構44にて前記可動枠56を介して前記農産物保持部８の前記各棒状部材55が畝Ｂの高さに応じて上下動可能に軸支されている。
【００４４】
前記リンク機構44は、図３に示すように、前記可動枠56と前記固定枠58との両側上下に平行に配置される前後方向に長手方向を有した上下のリンク62をそれぞれ有している。そして、前記両側上下のリンク62の一端部が前記固定枠58の上下の軸支体60にそれぞれ挿通した支軸61の両端部にそれぞれ回動自在に軸支され、これらリンク62の他端部が前記可動枠56の両側板部57の上下に支軸61にてそれぞれ回動自在に軸支されている。
【００４５】
つぎに、前記両側の農産物案内部９は、図１及び図４に示すように、前記両側の農産物保持部８の上方に位置して前記案内体43の両側に配設された案内側板46の下端部にそれぞれ形成されている。そして、この両側の農産物案内部９は、畝Ｂ上に上下に重なり合った状態で下側の農産物Ａの上面より上方に位置して下端側を畝Ｂの幅方向中央側に向けて突出した状態に傾斜した案内突片63にてそれぞれ形成されている。
【００４６】
また、前記両側の案内突片63は前記案内側板46の下端部にこの案内側板46から畝Ｂの幅方向中央側に向けて突出した状態に折り曲げて傾斜してそれぞれ一体に形成され、これら案内突片63の内面に衝撃を緩衝する前記緩衝材49が固着されている。
【００４７】
つぎに、前記実施の形態の作用を説明する。
【００４８】
トラクタの三点連結部に掘取機１の両側のロワアーム13のロワピン14及びトップアーム15の連結ピン16をそれぞれ連結し、トラクタのＰＴＯ軸に動力伝達軸を介して掘取機１のミッション装置17の入力軸19を連結する。また、必要に応じて掘取機１の両側の接地体７のそり体37をそれぞれ上下動して農産物を掘り取る農産物掘取体３の掘り取り深さを調節する。
【００４９】
また、トラクタにて掘取機１が牽引して進行され、トラクタのＰＴＯ軸にて動力伝達軸を介してミッション装置17の入力軸19が回転されると、この入力軸19にてベベルギヤ20，23を介して出力軸22が回転され、この出力軸22の回転でプーリ34，35及び無端ベルト36を介してコンベヤ６の駆動軸30が回転駆動され、この駆動軸30にてコンベヤ６の無端回行体５が回行され、この無端回行体５の往路側搬送面４が掘取機１の進行方向に対して後方に向かって移動される。
【００５０】
そして、図５に示すように、農産物掘取体３の掘取刃25にて玉葱、馬鈴薯等の農産物Ａが順次掘り取られるとともに、この掘取刃25からコンベヤ６の無端回行体５の往路側搬送面４上に農産物Ａが順次搬入される。
【００５１】
このとき、掘取刃25の後端部と往路側搬送面４の掘取刃25側の上面との間には、掘取刃25から往路側搬送面４上に土をなるべく送り込まないように往路側搬送面４の掘取刃25側を高くした多少の段差と隙間が形成されていることにより、往路側搬送面４の掘取刃25側の面で掘取刃25にて掘り上げられた土が砕かれるとともに、これらの土が掘取刃25の後端部と往路側搬送面４の掘取刃25側の上面との間の隙間から農産物を掘り取り後の畝Ｂに落下され、したがって、掘取刃25から往路側搬送面４上に送り込まれる土量が減少される。
【００５２】
また、往路側搬送面４にて農産物Ａが順次搬送されると、この往路側搬送面４の各搬送杆32にて農産物Ａがこれら各搬送杆32の間から土をふるい落としながら順次搬出部に向かって搬送され、この往路側搬送面４から農産物Ａの掘り取り後の畝Ｂ上に農産物Ａが順次搬出される。
【００５３】
このとき、コンベヤ６の後方に設けた案内体43は畝Ｂの畝幅の両側に配置した案内側板46とこの案内側板46の後端部間の後側案内板47とにより、コンベヤ６側を開口した平面視略コ字形状に形成されているため、畝幅の両側の案内側板46と後側案内板47とにより往路側搬送面４から搬出される農産物Ａが確実に農産物Ａの掘り取り後の畝Ｂ上に順次搬出される。
【００５４】
また、往路側搬送面４から搬出される農産物Ａが畝Ｂの畝幅の両側に配置した案内側板46または後側案内板47あるいはその両方に当接しても、この案内側板46及び後側案内板47の内側に固着した緩衝材49にて農産物Ａが損傷されることを確実に防止できる。
【００５５】
また、図５に示すように、振分体支持機構50にて支持されて案内体43の後側案内板47の中間部の下面に嵌合した状態に配置された振分体48の両振分板部54にて農産物Ａの掘り取り後の畝Ｂの表面上に搬出される農産物Ａが両側に振り分けられ、この振分体48の通過後の畝中央部は農産物Ａが存在しないトラクタまたは農産物Ａの拾い上げ作業機の走行タイヤの走行部や作業者の歩行部となる。
【００５６】
また、農産物Ａの掘り取り後の畝Ｂ幅の両側に位置する状態に配設された農産物保持部８の棒状部材55にて往路側搬送面４から畝Ｂ上に搬出された農産物Ａが畝Ｂ上に保持され、これらの農産物Ａが畝溝Ｃに落下することを防止される。
【００５７】
また、両側の農産物保持部８の棒状部材55にて畝Ｂ上に保持された農産物Ａ上に落下する農産物Ａが両側の農産物保持部８の棒状部材55の上方に位置して配設された両側の農産物案内部９の案内突片63にて畝Ｂの幅方向中央側に向けて案内され、これら農産物Ａが畝Ｂの幅方向中央側の畝Ｂ上に落下される。したがって、これら農産物Ａが畝Ｂ幅の両側で上下に重なり合うことを防止される。
【００５８】
また、両側の農産物案内部９の案内突片63にて農産物Ａを畝Ｂの幅方向中央側に案内するとき、案内突片63の内側に固着した緩衝材49にて農産物Ａが損傷されることを確実に防止される。
【００５９】
また、両側の農産物保持部８の棒状部材55にて保持された農産物Ａ上から畝Ｂの幅方向中央側の畝Ｂ上に農産物Ａが落下するとき、この農産物Ａにて畝Ｂ上に保持された農産物Ａが畝溝Ｃ側に押動されることがあっても、この押動される農産物Ａが両側の農産物保持部８の棒状部材55にて畝Ｂ上に保持されているため、この農産物Ａが畝溝Ｃに落下されることを確実に防止される。
【００６０】
したがって、これらの農産物Ａが畝Ｂ幅の両側で上下に重なり合うことを防止され、農産物掘取体３の掘取刃25にて掘り取られた農産物Ａを確実に拾い上げることができる状態に畝Ｂ上に農産物Ａを確実に集めることができ、これら農産物Ａの地干し効果を向上できる。
【００６１】
また、畝Ｂ幅の両側で農産物保持部８にて畝Ｂ上に農産物Ａを保持させるとき、両側の農産物保持部８は、リンク機構44にて畝Ｂの高さに応じて上下動可能に設けられていることにより、畝Ｂの高さが変化しても、その畝Ｂの高さに応じて農産物保持部８が上下動して進行し、この農産物保持部８にて畝Ｂ上に農産物Ａが確実に保持され、この農産物Ａが畝溝Ｃに落下することを確実に防止される。
【００６２】
そして、農産物保持部８は、掘取機１の進行方向に長手方向を有し上下に並設した棒状部材55にて形成したことにより、上下に並設した棒状部材55にて掘取機１の進行方向に長手方向を有した保持部が形成され、この棒状部材55の長手方向の保持部が進行しながらこの保持部にて畝Ｂ上に農産物Ａが確実に保持され、この農産物Ａが畝溝Ｃに落下することを更に確実に防止される。
【００６３】
また、上下に並設した棒状部材55にて農産物Ａを保持するとき、農産物Ａに接触する保持部の接触が小さく、農産物Ａの表皮等を損傷することを防止される。
【００６４】
また、両側の農産物案内部９は、畝Ｂ上に上下に重なり合った状態で下側の農産物Ａの上面より上方に位置して下端側を畝Ｂの幅方向中央側に向けて突出した状態に傾斜した案内突片63にて形成したことにより、上下に重なり合った状態での下側の農産物Ａ上から上側に搬出される農産物Ａを案内突片63にて畝Ｂの幅方向中央側に向けて確実に案内され、上側の農産物Ａが畝Ｂの幅方向中央側の畝Ｂ上にスムーズに確実に落下される。
【００６５】
また、この案内突片63が下側の農産物Ａの上面より上方に位置して形成されていることにより、この案内突片63にて上側の農産物Ａを畝Ｂの幅方向中央側に向けて案内するとき、下側の農産物Ａを畝Ｂの幅方向中央側に向けて移動することを防止される。
【００６６】
したがって、農産物掘取体３にて掘り取られた農産物Ａを確実に拾い上げることができる状態に畝Ｂ上に農産物Ａを確実に集めることができ、これらの農産物Ａが畝Ｂ幅の両側に上下に重なり合った状態になることがないので、これらの農産物Ａの地干し効果を向上できる。
【００６７】
また、トラクタにて農産物Ａの拾い上げ作業機を牽引して畝Ｂ上の地干しした農産物Ａを拾い上げるとき、トラクタのタイヤが走行する畝溝Ｃに畝Ｂ上から転がり落ちた農産物Ａが存在しないため、トラクタのタイヤで農産物Ａを踏み付けることがなく、農産物Ａの拾い上げ作業機にて畝Ｂ上の地干しした農産物Ａが確実に拾い上げられる。
【００６８】
つぎに、前記実施の形態では、そり体37の支柱40に固定した固定枠58にリンク機構44にて農産物保持部８を畝Ｂの高さに応じて上下動可能に設ける場合について説明したが、これに限らず、案内体43の両側の案内側板46にリンク機構44にて農産物保持部８を畝Ｂの高さに応じて上下動可能に設けるようにしてもよい。
【００６９】
【発明の効果】

  The guide protrusions 63 on both sides are formed integrally with each other by being bent and inclined at the lower end portion of the guide side plate 46 so as to protrude from the guide side plate 46 toward the center in the width direction of the flange B. The cushioning material 49 that cushions the impact is fixed to the inner surface of the protruding piece 63.
[0047]
  Next, the operation of the embodiment will be described.
[0048]
  The lower pin 13 of the lower arm 13 and the connecting pin 16 of the top arm 15 on both sides of the excavator 1 are connected to the three-point connecting portion of the tractor, respectively, and the mission device of the excavator 1 is connected to the PTO shaft of the tractor via the power transmission shaft. 17 input shafts 19 are connected. Moreover, the digging depth of the agricultural product digging body 3 digging up agricultural products by adjusting the sled bodies 37 of the grounding bodies 7 on both sides of the digging machine 1 up and down is adjusted as necessary.
[0049]
  Further, when the excavator 1 is pulled and advanced by the tractor and the input shaft 19 of the transmission device 17 is rotated by the PTO shaft of the tractor via the power transmission shaft, the bevel gear 20, The output shaft 22 is rotated through the output shaft 22, and the rotation of the output shaft 22 rotates the drive shaft 30 of the conveyor 6 through the pulleys 34, 35 and the endless belt 36. The turning body 5 is turned, and the forward-side transport surface 4 of the endless turning body 5 is moved backward with respect to the traveling direction of the excavator 1.
[0050]
  Then, as shown in FIG. 5, agricultural products A such as onions and potatoes are sequentially excavated by the excavation blade 25 of the agricultural product excavation body 3, and the endless rotating body 5 of the conveyor 6 is excavated from the excavation blade 25. Agricultural products A are sequentially carried onto the outbound side conveyance surface 4.
[0051]
  At this time, the soil is not sent as much as possible from the digging blade 25 onto the forward conveyance surface 4 between the rear end portion of the digging blade 25 and the upper surface of the forward conveyance surface 4 on the digging blade 25 side. Due to the formation of some steps and gaps that make the digging blade 25 side of the forward-side conveyance surface 4 higher, the digging blade 25 digs up the surface of the forward-side conveyance surface 4 on the digging blade 25 side. As the soil is crushed, these soils are dropped into the fence B after digging up agricultural products from the gap between the rear end portion of the digging blade 25 and the upper surface on the digging blade 25 side of the forward conveying side 4. Therefore, the amount of soil sent from the digging blade 25 onto the forward-side transport surface 4 is reduced.
[0052]
  Further, when the agricultural products A are sequentially transported on the forward path side transport surface 4, the agricultural products A are sequentially passed through the transport baskets 32 on the forward path side transport surface 4 while sifting the soil from the respective transport baskets 32 to the unloading unit. Agricultural products A are sequentially transported from the forward-side transport surface 4 onto the basket B after the agricultural products A are dug.
[0053]
  At this time, the guide body 43 provided on the rear side of the conveyor 6 has a guide side plate 46 arranged on both sides of the width of the flange B and a rear guide plate 47 between the rear ends of the guide side plate 46. Since the opening is formed in a substantially U shape in plan view, the agricultural product A unloaded from the forward-side transport surface 4 is surely dug out by the guide side plate 46 and the rear side guide plate 47 on both sides of the ridge width. It is sequentially carried out on the rear basket B.
[0054]
  Further, even if the agricultural product A carried out from the forward-side conveyance surface 4 comes into contact with the guide side plate 46 and / or the rear side guide plate 47 arranged on both sides of the width of the ridge B, the guide side plate 46 and the rear side guide It is possible to reliably prevent the produce A from being damaged by the cushioning material 49 fixed to the inside of the plate 47.
[0055]
  Further, as shown in FIG. 5, both vibrations of the distributing body 48 supported by the distributing body support mechanism 50 and arranged in a state of being fitted to the lower surface of the intermediate portion of the rear guide plate 47 of the guide body 43 are arranged. Agricultural products A carried out on the surface of the basket B after excavation of the agricultural products A are distributed to both sides by the dividing plate 54, and the central part of the basket after passing through the distribution body 48 is a tractor in which the agricultural products A are not present. It becomes the traveling part of the traveling tire of the working machine for picking up the agricultural product A and the walking part of the worker.
[0056]
  Further, the agricultural product A carried out from the forward-side transport surface 4 onto the ridge B by the rod-like members 55 of the agricultural product holding section 8 disposed on both sides of the width of the ridge B after the digging of the agricultural product A is removed. It is held on B and prevents these agricultural products A from falling into the trough C.
[0057]
  In addition, the produce A falling on the produce A held on the basket B by the rod-like members 55 of the produce holding units 8 on both sides is disposed above the rod-like members 55 of the produce holding units 8 on both sides. The guide protrusions 63 of the agricultural product guides 9 on both sides are guided toward the center in the width direction of the basket B, and these agricultural products A are dropped onto the center of the basket B in the width direction. Therefore, these agricultural products A are prevented from overlapping vertically on both sides of the ridge B width.
[0058]
  Further, when the agricultural product A is guided to the center side in the width direction of the ridge B by the guide protrusions 63 of the agricultural product guides 9 on both sides, the agricultural product A is damaged by the cushioning material 49 fixed inside the guide protrusions 63. That is surely prevented.
[0059]
  Further, when the produce A falls from the produce A held by the rod-like members 55 of the produce holding parts 8 on both sides onto the basket B at the center in the width direction of the kite B, the produce A is held on the kite B. Even if the produced product A is pushed to the ridge groove C side, the pushed produce A is held on the ridge B by the rod-like members 55 of the produce holding parts 8 on both sides. This produce A is surely prevented from dropping into the trough C.
[0060]
  Therefore, these agricultural products A are prevented from overlapping vertically on both sides of the ridge B, and the cultivated product A excavated by the digging blade 25 of the agricultural product digging body 3 can be reliably picked up. Agricultural products A can be reliably collected on the top, and the effect of drying these agricultural products A can be improved.
[0061]
  In addition, when the agricultural product A is held on the basket B by the agricultural product holding unit 8 on both sides of the width of the basket B, the agricultural product holding unit 8 on both sides can be moved up and down according to the height of the basket B by the link mechanism 44. By being provided, even if the height of the basket B changes, the agricultural product holding unit 8 moves up and down according to the height of the basket B, and the agricultural product holding unit 8 moves onto the basket B. The agricultural product A is securely held, and the agricultural product A is reliably prevented from falling into the trough C.
[0062]
  And the agricultural product holding | maintenance part 8 has the longitudinal direction in the advancing direction of the excavator 1, and was formed in the bar-shaped member 55 arranged in parallel up and down, so that the excavator 1 in the bar-shaped member 55 arranged in parallel up and down. A holding portion having a longitudinal direction in the traveling direction is formed, and while the holding portion in the longitudinal direction of the rod-like member 55 advances, the produce A is securely held on the ridge B by the holding portion, and the produce A is It is further reliably prevented from falling into the groove C.
[0063]
  Further, when the agricultural product A is held by the bar-shaped members 55 arranged in the vertical direction, the contact of the holding portion that contacts the agricultural product A is small, and damage to the skin of the agricultural product A and the like is prevented.
[0064]
  In addition, the agricultural product guides 9 on both sides are positioned above the upper surface of the lower agricultural product A in a state where the agricultural product guides 9 are vertically overlapped with the upper side of the basket B, and protruded toward the center in the width direction of the basket B. By forming with the inclined guide protrusion 63, the agricultural product A transported upward from the lower agricultural product A in the state of being overlapped vertically is directed toward the center in the width direction of the ridge B with the guide protrusion 63. The upper produce A is smoothly and reliably dropped onto the ridge B on the center side in the width direction of the ridge B.
[0065]
  Further, since the guide protrusion 63 is formed above the upper surface of the lower agricultural product A, the upper agricultural product A is directed toward the center in the width direction of the ridge B by the guide protrusion 63. When guiding, it is prevented that the lower agricultural product A is moved toward the center in the width direction of the basket B.
[0066]
  Therefore, it is possible to reliably collect the agricultural products A on the ridge B so that the agricultural products A excavated by the agricultural product excavation body 3 can be surely picked up, and these agricultural products A are vertically moved on both sides of the width of the ridge B. Therefore, it is possible to improve the effect of drying these agricultural products A.
[0067]
  In addition, when the tractor picks up the agricultural product A and picks up the dried agricultural product A on the hoe B, there is no agricultural product A rolling down from the hoe B in the grooving C where the tire of the tractor travels. Therefore, the agricultural product A on the fence B can be surely picked up by the picking machine for the agricultural product A without stepping on the agricultural product A with the tire of the tractor..

【The invention's effect】
  According to the first aspect of the present invention, it is possible to reliably prevent the agricultural products carried out on the surface of the ridge after the agricultural product has been dug from the forward-side conveyance surface of the conveyor from rolling down to the ridge groove or the ridge side adjacent to the ridge. Agricultural products can be reliably collected on the surface of the fence in a state where the agricultural products excavated by the agricultural product excavation body can be surely picked up, and the land drying effect of the agricultural products can be improved.In addition, even if the height of the ridge changes, the agricultural product holding part moves up and down reliably according to the height of the ridge, and the agricultural product on the ridge falls into the ridge groove by this agricultural product holding. It can be reliably prevented.
