【発明の属する技術分野】
本発明は、植立茎稈作物の刈取機における分草杆の安全装置に関するものである。
詳しくは、直立茎稈の各条毎に対応する刈取機において、接地体を備えた刈取処理部の分草杆を個別に上下揺動自在に構成した状態で複数個左右に並列する刈取機構を有する収穫機の構造に係るものである。
【０００２】
【従来の技術】
従来、直立茎稈の各畦毎に対応する刈取機には接地体となる分草杆（デバイダー）が上下揺動自在に取付けられているが、この分草杆の先端には安全装置がない。
【０００３】
【発明が解決しようとする課題】
従来の技術で述べたものにあっては、下記のような問題点を有していた。
常に、接地状態を必要とする圃場（作物が倒状し地を這うようにできているような圃場）において、機体がバウンドしたり、畑に凹凸の多い所では分草杆が上下に揺動自在とは云え追従できず、地中に突き刺さり分草杆を破損するばかりか、刈取機本体の破損を生じることも少なからず発生している。
加えて、地上を這うようになっている作物が分草杆の下をくぐり刈取られなく機械に詰まってしまうことが多く、作業能率が非常に悪くなっていた。
