【発明の属する技術分野】
本発明は、畦形成機における畦形成装置の構成に関する。
【0002】
【従来の技術】
従来の畦形成機における畦形成装置の構成として、同一出願人により、トラクタに装着され畦形成箇所に沿って移動され、畦形成箇所に土を盛り上げ状態に供給する土盛装置と、土盛装置の移動方向の後方に設置される畦形成装置とを有し、畦形成装置は土を盛り上げ状態とされた畦形成箇所の上を回転しながら通過させる円筒回転体と、円筒回転体の回転駆動力供給側に取り付けられ回転駆動供給側にいく程径大となり、円筒回転体の中央に向けた傾斜面を有するとともに、表面は放射状の分割片に分割され、各々の分割片は進行方向に対して前進角を設けてなり、隣接する分割片の相互は逃げ角をもって側面視ジグザグ状に連結される円錐回転体とからなる畦形成機が提案され公知である。(特許文献1)

【特許文献1】
特許第3148678号明細書
【0004】
【発明が解決しようとする課題】
従来技術の構成では、放射状に形成された分割片の回転方向に対する後端縁を直線状としているため、粘土質圃場での畦形成作業を行う場合、分割片の後端部に粘土質の土が付着し形成する畦の表面をまくり上げ波立たせ仕上りが粗悪となる。又、粘性がさらに強くなった圃場では形成する畦の表面を剥離させ、団子状にまるめ込み畦形成面の仕上りが悪くなる。
【0005】
そこで本発明は、畦形成機における畦形成装置の構造を見直し、粘土質圃場においても仕上りの良い畦形成装置を備えた畦形成機を提供することを目的とする。
【0006】
【課題を解決するための手段】
上記課題を解決するために、走行車に装着するための装着部と、旧畦を砕土する砕土爪を有した土盛装置と、砕土された旧畦の上面を形成する上面形成体と側面を形成する側面形成体からなる畦形成装置とを有し、土盛装置と畦形成装置は回転駆動され畦形成作業を行なう畦形成機において、側面形成体は上面形成体の一端部より外方に向け径大となる円錐面を有し、表面は放射状に分割され連続した複数の分割片にて構成され、この分割片は、回転方向に対し前進角を設け後端部に隣接させた分割片の前方部を重合させて構成するとともに、回転方向に対し後端縁を波形形状としたことにより、分割片の後端部に土が付着することなく、土離れが良くなりきれいな畦を形成することができる。
【0007】
【発明の実施の形態】
本発明を実施した図面に基づいて構成を説明する。図1は本発明を実施した畦形成機の平面図、図2は同畦形成機の畦形成装置の斜視図、図3は同畦形成機の畦形成装置の分割片を示す平面図、図4は畦形成作業を示す斜視図、図5は分割片の作用図である。
【0008】
図1において、Aは畦形成機を示し、1の装着部、2の土盛装置、3の畦形成装置から構成される。
【0009】
1の装着部は、水平方向に延設したフレーム11と、このフレーム11より前方に突設され、図示されていないが走行車であるトラクタの三点リンクに装着される装着マスト12と、フレーム11の略中央部にはミッションケース13が配置され構成される。
【0010】
ミッションケース13には前方に向けた入力軸13aが設けられ、この入力軸13aは、図示されていないがトラクタPTO軸よりユニバーサルジョイント14を介しトラクタの駆動力を畦形成機Aへ入力するものである。
【0011】
2の土盛装置は、砕土爪21を爪軸22の軸芯に対し放射状に複数設けたロータリ23と、このロータリ23を回転駆動するためロータリ23の一端を固着するロータリ出力軸24を有したロータリ駆動ケース25により構成され、前記装着部1のフレーム11の一端にロータリ23を作業進行方向に対し前方に配置するよう支持される。前記ロータリ駆動ケース25の内部には、チェーン減速機26が備えてある。
【0012】
3の畦形成装置は、前記土盛装置2の後方に配置され、旧畦の上面を形成する上面形成体31と、旧畦の側面を形成する側面形成体32と、この上面形成体31と側面形成体32を回転駆動するための畦形成駆動軸33を有した畦形成駆動ケース34とから構成され、前記装着部1のフレーム11の一端に、前記ロータリ駆動ケース25とともに支持される。前記畦形成駆動ケース34の内部には、チェーン減速機35が備えてある。
【0013】
駆動伝達について説明すると、前記ミッションケース13より前方に突設させた入力軸13aに、図示されていないがトラクタPTO軸よりユニバーサルジョイント14を介し駆動力が入力されると、ミッションケース13の内部に設けたベベルギヤ13b,13cを介し減速され、水平方向に延設しパイプ体にて構成されたフレーム11の内部に回転可能に設けた駆動軸13dへと伝達する。
【0014】
ロータリ駆動ケース25内部に備えたチェーン減速機26は、前記駆動軸13dに固着されたスプロケット26aと、前記ロータリ出力軸24の内方端に固着したスプロケット26bと、これらスプロケット26a,26bに巻架したチェーン26cから構成され、駆動軸13dが駆動することにより、ロータリ出力軸24に固着されたロータリ23をチェーン減速機26によりさらに減速し回転させる。
【0015】
畦形成駆動ケース34の内部に備えたチェーン減速機35は、前記駆動軸13dに固着したスプロケット35aと、畦形成駆動ケース34から水平方向に突出する畦形成出力軸33の内方端に固着したスプロケット35bと、これらスプロケット35a,35bに巻架したチェーン35cから構成され、駆動軸13dが駆動することにより、畦形成出力軸33に固着された上面形成体31及び側面形成体32をチェーン減速機35によりさらに減速し回転させる。
【0016】
図2及び図3に基づいて畦形成装置3の上面形成体31及び側面形成体32のについて説明する。上面形成体31は、前記畦形成出力軸33の外方端部に取り付けられるボス31aと、このボス31aに嵌合する円筒形状の上面ローラ31bから構成され、側面形成体32は、前記上面形成体31の一端部となるボス31aの外周部より畦形成駆動軸33側となる外方へ向け徐々に径大となる円錐面を形成するよう放射状に分割し、連結させ複数設けた分割片32aと各々の分割片32aを連結するため外周部にリング32bを設け構成される。
【0017】
分割片32aは、回転方向fに対し後方となる後端縁に波形部aを形成している。連続させて複数設けた分割片32aは回転方向fに対し前進角が設けられ、後端部に隣接させた分割片32aの前方部を下面に重合させ、段差を設けて側面視ジグザグ状に配置し円錐面を形成する。
【0018】
このように構成した畦形成装置3の作用は図4及び図5に示すように、図示されていないがトラクタに装着されF方向に走行しながら畦形成装置3の上面形成体31と側面形成体32をf方向に回転駆動させ、土盛装置2にて砕土された旧畦の畦形成作業を行う。前記上面形成体31と側面形成体32の回転速度は、トラクタ作業速度すなわち走行速度より速く回転するよう設定され、畦形成面をスリップ状態で締上げる。
【0019】
分割片32aの後端部は、上面形成体31の一端部より外方へ向け徐々に径大とし、側面形成体32の回転軌跡となる円錐面S1と一致させ回転方向fに対し前進角αを設けるとともに、後端部に隣接させた分割片32aの前方部を下面に重合させ側面視ジグザグ状とする。この側面視ジグザク状とした段差を有した円錐面にて畦形成面Hに対し断続した圧力をかけ畦側面を締上げる。
【0020】
そして、分割片32aの後端部に形成された波形部aは、回転中心Gに対し波形形状の頂点部を結ぶ半径Raと、波形形状の谷部を結ぶ半径Rbに差を設けることで、畦形成面Hに対する押圧量が変化し押圧力が加減され、図4に示すように畦形成面Hは押圧力が分散され粘土質の土に対して土離れが良く、適度な圧力で締上げることができる。
【0021】
【発明の効果】
以上のように、側面形成体の分割片の後端部に波形形状を有することで、畦形成面に対し押圧量を変化させ押圧力を加減することができるので、畦形成面は押圧力が分散され粘土質の土に対し土離れがよく適度な圧力で締上げることができ、きれいな畦を形成することができる。
