Description

【０００１】
【発明の属する技術分野】
本発明は、畦塗り機に関し、特に、旧畦を切り崩して土盛りを行なう前処理部及び盛られた土を切り崩された旧畦上に塗り付ける整畦部を備えてなる畦塗り機に関する。
【０００２】
【従来の技術】
このような畦塗り機は、トラクタ等の走行機体に装着されて、走行機体の走行位置に対して側方にオフセットした位置で畦塗り作業を行なう。畦塗り機は、旧畦を切り崩して土盛りを行なう前処理部と、盛られた土を切り崩された旧畦上に塗り付ける整畦部を備え、走行機体の前進動とともに畦塗り作業を行なう（特許文献１参照）。
【０００３】
この畦塗り機の前処理部及び整畦部は、走行機体の後部に装着された箱状の機枠の側部に前後方向に所定間隔を有して側方に突設された一対のブラケットにそれぞれが取り付けられる。機枠には回転動自在に支持されて走行機体からの駆動力が伝達される主軸が設けられ、この主軸には、主軸と前処理部間及び主軸と整畦部間を繋ぐ回転機構がそれぞれに接続されている。このため、前処理部及び整畦部は、主軸及び回転機構を介して走行機体からの駆動力が伝達される。
【０００４】
【特許文献１】
特開平１１−２４３７０６号公報（第２頁、第２図）
【０００５】
【発明が解決しようとする課題】
ここで、前処理部を支持するブラケットと前処理部に駆動力を伝達する回転機構は別個に配設され、また整畦部を支持するブラケットと整畦部に駆動力を伝達する回転機構も別個に配設されている。このため、従来の畦塗り機は、構造が複雑になり、大型化するという問題が生じる。
【０００６】
また、回転機構は外部に露出しているので、畦塗り作業時において、土が回転機構に付着して前処理部や整畦部に伝達される動力を低下させる。このため、従来の畦塗り機では畦塗り作業が不十分になったり、露出した回転機構が破損する虞があるという問題が生じる。そこで、土が回転機構に付着しても、前処理部や整畦部による畦塗り作業が十分に行なえるようにするため、走行機体に搭載されるエンジンを高馬力のものにすればよいが、既存の走行機体に搭載されたエンジンを高馬力のものに取り替えたり、高馬力のエンジンを搭載した走行機体を新たに用意したりするのは、極めて非経済的である。
【０００７】
本発明は、このような問題に鑑みてなされたものであり、旧畦を切り崩して土盛りを行なう前処理部と、盛られた土を切り崩された旧畦上に塗り付ける整畦部を備えた畦塗り機において、畦塗り機の構造を簡略化して小型化するとともに、走行機体から前処理部や整畦部に伝達される動力を低下せない畦塗り機を提供することを目的とする。
【０００８】
【課題を解決するための手段】
上記目的を達成するために本発明に係わる畦塗り機は、走行機体に装着され、該走行機体の走行位置に対して側方にオフセットした位置に配置され、旧畦を切り崩して土盛りを行なう前処理部及び盛られた土を切り崩された旧畦上に塗り付ける整畦部を備え、走行機体の前進動とともに畦塗り作業を行なう畦塗り機であって、上下方向に延びて回転動自在に支持されて走行機体からの駆動力を受けて回転動する回転軸を内部に収容する回転軸ケースと、一端側が該回転軸ケースに接続されて他端側が前処理部に接続され、該前処理部を支持するとともに回転軸からの動力を前処理部に伝達可能な前処理動力伝達機構を内部に有してなる前処理動力伝達ケースと、一端側が該回転軸ケースに接続されて他端側が整畦部に接続され、該整畦部を支持するとともに回転軸からの動力を整畦部に伝達可能な整畦動力伝達機構を内部に有してなる整畦動力伝達ケースとを有し、回転軸ケース、前処理動力伝達ケース及び整畦動力伝達ケースが一体的に形成され、前処理部の回転中心軸は、平面視において整畦部の回転中心軸と交差する方向に延びる。
【０００９】
上記構成の畦塗り機によれば、回転軸ケース、前処理動力伝達ケース及び整畦動力伝達ケースを一体的に形成することで、前処理部を支持する部分と前処理部に駆動力を伝達する部分を近接した位置に配置することができ、整畦部を支持する部分と整畦部に駆動力を伝達する部分を近接した位置に配置することができる。このため、畦塗り機の構造を簡略化して小型化することができる。また、回転軸ケース内に回転軸が収容され、前処理動力伝達ケース内に前処理動力伝達機構が収容され、整畦動力伝達ケース内に整畦動力伝達機構が収容されるので、畦塗り機による畦塗り作業時において、土が回転軸、前処理動力伝達機構及び整畦動力伝達機構に付着することはない。このため、走行機体から回転軸に伝達される駆動力が前処理部及び整畦部に伝達されるまでの間において、この駆動力が小さくなる事態を未然に防止することができ、また各伝動機構が損傷する虞を防止することができる。さらに、前処理部の回転中心軸を平面視において整畦部の回転中心軸と交差する方向に延ばすことで、前処理部により土盛りされる土の流れの方向を整畦部側にすることができる。このため、整畦部に供給される土の流れがスムースになり、前処理部から旧畦上に供給される土を効率的に旧畦上に塗り付けることができる。
【００１０】
上記構成の畦塗り機において、前処理部の回転中心軸は、平面視において整畦部の回転中心軸と交差する方向に且つ非直交する方向に延ばしてもよい。
【００１１】
上記構成の畦塗り機によれば、前処理部の回転中心軸は、平面視において整畦部の回転中心軸と交差する方向に且つ非直交する方向に延びることで、前処理部により土盛りされる土の流れの方向を確実に整畦部側にすることができる。このため、整畦部に供給される土の流れがよりスムースになり、前処理部から旧畦上に供給される土を効率的に旧畦上に塗り付けることができる。
【００１２】
上記構成の畦塗り機において、前処理部は、その先端部が旧畦に対向した位置にあるときに、該先端部が旧畦の上部から下部側へ移動する方向に回転動するようにしてもよい。
【００１３】
上記構成の畦塗り機によれば、前処理部の回転方向を前処理部の先端部が旧畦の上部から下部側へ移動する方向にすることで、前処理部により切り崩された土は前処理部の回転動に沿って旧畦の下部から一旦離反する側に移動した後に上方に移動し、旧畦の上方位置から旧畦の上部に供給される。このため、切り崩された土は無駄なく旧畦に土盛りされ、必要な盛土量を容易に確保することができ、堅牢な新畦を形成することができる。
【００１４】
本発明に係わる畦塗り機は、走行機体に前端側が回動自在に取り付けられて後端側が左右方向に旋回動可能なオフセットフレームと、該オフセットフレームの後端部に水平方向に回動自在な作業部を有し、該作業部は、オフセットフレームの後端部に設けられた請求項１に記載の回転軸ケースに一体的に形成された請求項１に記載の前処理動力伝達ケースに接続された請求項１から３のいずれかに記載の前処理部と、回転軸ケースに一体的に形成された請求項１に記載の整畦動力伝達ケースに接続された請求項１に記載の整畦部を有してなる。
【００１５】
上記構成の畦塗り機によれば、オフセットフレームの後端部に作業部を水平方向に回動自在に設け、作業部は、請求項１に記載の回転軸ケースに一体的に形成された請求項１に記載の前処理動力伝達ケースに接続された請求項１から３のいずれかに前処理部と、回転軸ケースに一体的に形成された請求項１に記載の整畦動力伝達ケースに接続された請求項１に記載の整畦部を有してなることで、前処理部及び整畦部を支持する部分とこれらに動力を伝達する部分を近接した位置に配置することができ、オフセットフレーム及び作業部を有してなる畦塗り機の構造を簡略化して小型化することができる。また前処理部及び整畦部に動力を伝達する伝動機構が前処理動力伝達ケース及び整畦動力伝達ケース内に収容されるので、畦塗り作業時の土が伝達機構に付着することはなく、走行機体から回転軸に伝達される駆動力が前処理部及び整畦部に伝達されるまでの間において、この駆動力が小さくなる事態を未然に防止することができ、また各伝動機構が障害物当に接触して損傷する虞を防止することができる。さらに、前処理部の回転中心軸を平面視において整畦部の回転中心軸と交差する方向に延ばすことで、整畦部に供給される土の流れがスムースになり、前処理部から旧畦上に供給される土を効率的に旧畦上に塗り付けることができる。
【００１６】
【発明の実施の形態】
以下、本発明の好ましい実施の形態を図１から図６に基づいて説明する。本実施の形態は、畦塗り機の一例として、天場処理部、前処理部及び整畦部を備えてなる作業部が水平方向に回動可能である畦塗り機の態様を示す。なお、説明の都合上、図１（斜視図）に示す矢印の方向を前後方向及び左右方向として以下説明する。
【００１７】
畦塗り機１は、図２（ｂ）（平面図）に示すように、トラクタ等の走行機体８０の後部に配設された三点リンク連結機構８１に着脱可能に装着されるヒッチフレーム３に前端側が回動自在に取り付けられて後端側が左右方向に旋回動可能なオフセットフレーム５と、オフセットフレーム５の後端部に水平方向に回動可能に連結された作業部２０を有してなる。
【００１８】
ヒッチフレーム３の左右方向の中央下部には、図１（斜視図）に示すように、ギアボックス６が設けられている。ギアボックス６の入力軸６ａには図２に示す走行機体８０のＰＴＯ軸（図示せず）から図示しない中間フレームの伝動軸を介して動力が伝達される。オフセットフレーム５は内部が中空な箱状部材であり、オフセットフレーム５の後端部には上下方向に延びて回転動自在に支持された駆動軸７が設けられている。この駆動軸７は、ギアボックス６の入力軸６ａ及びオフセットフレーム５内に配設されたチェーン伝動機構（図示せず）を介して走行機体からの駆動力が伝達されるように構成されている。
【００１９】
オフセットフレーム５は、一端部がオフセットフレーム５の後側上部に枢結され他端部がヒッチフレーム３の上部に枢結された旋回シリンダ８の伸縮動作により左右方向に旋回動可能である。
【００２０】
オフセットフレーム５の後端下部には、図３（断面図）に示すように、図１に示す駆動軸７の下部に連結されて垂直下方へ延びる回転軸１０が設けられている。なお、図３は、図２（ａ）のＩＩ−ＩＩ矢視に相当する部分の断面図を示す。
回転軸１０は図１に示す駆動軸７と同軸上に配置されている。回転軸１０の外側には回転軸１０を覆う円筒状の回転軸ケース１１が配設され、その上端部はオフセットフレーム５の後端下部に回動自在に接続されている。回転軸ケース１１は、図１に示すように、一端部がオフセットフレーム５の側部に枢結されて他端部が回転軸ケース１１に枢結された回動シリンダ１３の伸縮動作により水平方向に回動可能である。このため、回転軸ケース１１に接続される作業部２０は、回動シリンダ１３の伸縮動作により回転軸ケース１１を介して水平方向に回動可能である。
【００２１】
回転軸ケース１１に取り付けられる作業部２０は、圃場の周辺に沿って形成された旧畦の上部を切り崩す天場処理部２１と、切り崩した土の土盛りを行なう前処理部３１と、盛られた土を切り崩された旧畦上に塗り付ける整畦部４１を有してなる。
【００２２】
前処理部３１は、図４（部分断面図）に示すように、前後方向に延びて回転動自在に支持された回転中心軸３２と、回転中心軸３２の外周に放射状に取り付けられた複数の耕耘爪３４を有してなる。なお、図４は、図２（ａ）のＩＩ’−ＩＩ’矢視に相当する部分の部分断面図を示す。前処理部３１には、これを回転自在に支持する前処理動力伝達ケース５０が接続されている。前処理動力伝達ケース５０は回転軸ケース１１側へ延び、その後端部は回転軸ケース１１の側部にボルト等の締結手段５１により固定されている。前処理動力伝達ケース５０は円筒状であり、前処理動力伝達ケース５０内には回転軸１０からの動力を前処理部３１に伝達可能な前処理動力伝達機構５３が設けられている。
【００２３】
前処理動力伝達機構５３は、図３に示すように、シャフト伝動機構であり、前側端部が前処理部３１の回転中心軸３２に連結されて後側端部が回転軸ケース１１に回転動自在に支持された前処理動力伝達シャフト５４を有する。前処理動力伝達シャフト５４は図示しないギアを介して回転軸１０からの駆動力が伝達可能に構成されている。このため、前処理部３１は、前処理動力伝達シャフト５４を介して回転軸１０からの駆動力が伝達可能である。前処理部３１の回転方向は、図５に示すように、耕耘爪３４の先端部が旧畦Ｕ０に対向した位置にあるときに、該先端部が旧畦Ｕ０の上部から下部側へ移動する方向、即ち、図５の矢印Ａの示す方向である。なお、図３に示す前処理動力伝達機構５３はシャフト伝動機構に限るものではなく、チューン伝動機構でもよい。
【００２４】
前処理部３１の回転中心軸３２は、図３に示すように、平面視において整畦部４１の回転中心軸４２と交差する方向に且つ非直交する方向に延びる。傾斜する回転中心軸３２を備える前処理部３１の作動については後述する。前処理部３１には、この上側を覆う前処理カバー３５が設けられている。
【００２５】
整畦部４１は、図４に示すように、左右方向に延びて回転動自在に支持された回転中心軸４２と、回転中心軸４２に取り付けられ内側に進むに従って径が拡開する多面体ドラム４３と、多面体ドラム４３の右側端部に取り付けられて水平方向に延びる円筒部４４を有してなる。多面体ドラム４３は新畦Ｕ１の法面Ｕｆを形成し、円筒部４４は新畦Ｕ１の天場Ｕｔを形成する。整畦部４１の作動については後述する。整畦部４１には、これを回転動自在に支持する整畦動力伝達ケース６０が接続されている。整畦動力伝達ケース６０は、右側端部が多面体ドラム４３の内部に配置されて水平方向に延びる円筒状の第１整畦動力伝達ケース６１と、第１整畦動力伝達ケース６１の左側端部に接続されて前側に延びて前側端部が回転軸ケース１１の左側端部にボルト等の締結手段５１により固定された内部が中空な第２整畦動力伝達ケース６２を有してなる。
【００２６】
整畦動力伝達ケース６０内には、回転軸１０からの動力を整畦部４１に伝達可能な整畦動力伝達機構が設けられている。整畦動力伝達機構６３は、図３に示すように、第１整畦動力伝達ケース６１内に配設されたシャフト伝動機構６４と、第２整畦動力伝達ケース６２内に設けられたチェーン伝動機構６７と、第２整畦動力伝達ケース６２の前端部内に設けられたシャフト伝動機構７１を有する。第１整畦動力伝達ケース６１内のシャフト伝動機構６４は、第１整畦動力伝達ケース６１内に回転動自在に支持された第１整畦動力伝達シャフト６５を有する。第１整畦動力伝達シャフト６５の右側端部は整畦部４１の回転中心軸４２に連結され、第１整畦動力伝達シャフト６５の左側端部は第１整畦動力伝達ケース６１から突出して第２整畦動力伝達ケース６２内に延びる。
【００２７】
第２整畦動力伝達ケース６２の前端部内のシャフト伝動機構７１は、右側端部が回転軸ケース１１内に回転動自在に支持されて第２整畦動力伝達ケース６２の前端部内に延びる第２整畦動力伝達シャフト７２を有してなる。第２整畦動力伝達ケース６２内のチェーン伝動機構６７は、第１整畦動力伝達シャフト６５の左側端部に取り付けられた第１スプロケット６８と、第２整畦動力伝達シャフト７２に取り付けられた第２スプロケット６９と、第１スプロケット６８及び第２スプロケット６９間に掛け回されたチェーン７０を有してなる。このため、整畦部４１は、第２整畦動力伝達シャフト７２、チェーン７０及び第１整畦動力伝達シャフト６５を介して回転軸１０からの駆動力が伝達可能である。なお、第２整畦動力伝達ケース６２内のチェーン伝動機構６７はシャフト伝動機構にしてもよい。
【００２８】
天場処理部２１は、下部が開口したカバー部材２２に水平方向に延びて回転動自在に支持された回転中心軸２３と、回転中心軸２３の外周に放射状に取り付けられた複数の削土爪２４を有してなる。カバー部材２２の左側端部には天場動力伝達ケース９０が接続される。天場動力伝達ケース９０は前処理部３１を囲むようにして配置され、先端部が第２整畦動力伝達ケース６２の前端部に接続されている。天場動力伝達ケース９０は、カバー部材２２に接続されて左側へ延びる円筒状の第１天場伝達ケース９１と、第１天場伝達ケース９１の左側端部に接続されて後方側へ延びて内部が中空な第２天場伝達ケース９２と、第２天場伝達ケース９２の後端部に接続されて第２整畦動力伝達ケース６２の前端部に接続されて内部が中空な第３天場伝達ケース９３を有してなる。
【００２９】
天場動力伝達ケース９０内には回転軸１０の駆動力を天場処理部２１に伝達可能な天場動力伝達機構９５が設けられている。天場動力伝達機構９５は、第１天場伝達ケース９１内に配設されたシャフト伝動機構９６と、第２天場伝達ケース９２内に配設されたチェーン伝動機構９９と、第３天場伝達ケース９３内に配設されたシャフト伝動機構１０５を有する。第１天場伝達ケース９１内のシャフト伝動機構９６は、回転動自在に支持されて右側端部が天場処理部２１の回転中心軸２３に連結され、左側端部が第１天場伝達ケース９１から突出して第２天場伝達ケース９２内に延びる第１天場伝達シャフト９７を有してなる。第３天場伝達ケース９３内のシャフト伝動機構１０５は、第３天場伝達ケース９３内に回転動自在に支持されて右側端部が第２整畦動力伝達シャフト７２に連結された第２天場伝達シャフト１０６を有してなる。第２天場伝達シャフト１０６の左側端部は第３天場伝達ケース９３から突出して第２天場伝達ケース９２内に延びる。第２天場伝達ケース９２内のチェーン伝動機構９９は、第１天場伝達シャフト９７の左側端部に取り付けられた第１スプロケット１００と、第２天場伝達シャフト１０６に取り付けられた第２スプロケット１０１と、第１スプロケット１００及び第２スプロケット１０１間に掛け回されたチェーン１０２を有してなる。このため、天場処理部２１は、第２整畦動力伝達シャフト７２、第２天場伝達シャフト１０６、チェーン１０２、第１天場伝達シャフト９７を介して回転軸１０からの駆動力が伝達される。
【００３０】
このように、本発明に係わる畦塗り機１の作業部２０を構成する天場処理部２１、前処理部３１及び整畦部４１は、内部に動力伝達機構を内蔵した伝達ケースを介して回転軸ケース１１の周りに一体的に形成されている。このため、天場処理部２１、前処理部３１及び整畦部４１の各部を支持する部分と、各部に駆動力を伝達する部分を近接した位置に配置することができ、畦塗り機１の構造を簡略化して小型にすることが可能である。
【００３１】
また、天場動力伝達ケース９０内に天場動力伝達機構９５が収容され、前処理動力伝達ケース５０内に前処理動力伝達機構５３が収容され、整畦動力伝達ケース６０内に整畦動力伝達機構６３が収容されているので、畦塗り機１による畦塗り作業時において、土が天場動力伝達機構９５、前処理動力伝達機構５３及び整畦動力伝達機構６３に付着することはない。このため、回転軸１０から天場処理部２１、前処理部３１及び整畦部４１に伝達される動力が小さくなる事態を未然に防止することができる。その結果、図２（ｂ）に示すように、走行機体８０に馬力の大きなエンジンを載せ替える必要がなくなり、また馬力が大きいエンジンを搭載した新たな走行機体を用意する必要がなく、既存の走行機体の継続使用が可能となり極めて経済的である。
【００３２】
また、図３に示すように、前処理部３１の回転中心軸３２の延びる方向は、前述したように整畦部４１の回転中心軸４２に交差する方向且つ非交差する方向であり、また前処理部３１の回転方向は前処理部３１の先端部が旧畦Ｕ０の上部から下部側へ移動する方向である。このため、畦塗り機１により矩形状の圃場の一辺を畦塗りする場合、畦塗り機１を一辺に沿って前側に移動させると、天板処理部２１により旧畦Ｕ０の上部の土や草等が削り取られて圃場内に飛ばされる。そして、図５に示すように、前処理部３１により旧畦Ｕ０の内側法面Ｕｆが上部から下部に向かって切り崩され、切り崩された土は前処理部３１の回転動に沿って旧畦Ｕ０の下部から一旦離反する側に移動した後に上方に移動し、さらに切り崩された土は前処理カバー３５に案内されて旧畦Ｕ０の上方位置から旧畦Ｕ０の上部に供給される。このため、切り崩された土が旧畦Ｕ０の上部に移動されるまでの流れをスムースにすることができる。その結果、切り崩された土を無駄なく旧畦Ｕ０に土盛りすることができ、必要な盛土量を容易に確保することができ、堅牢な新畦Ｕ１を形成することができる。
【００３３】
なお、前処理部３１は、図６（部分断面図）に示すように、前処理部３１の回転中心軸３２の延びる方向と整畦部４１の回転中心軸４２の延びる方向とのなす角度θが鋭角をなす方向に配置してもよい。また、前処理部３１に設けられた耕耘爪３４はその先端部が多面体ドラム４３の近傍位置まで延びるように形成してもよい。このように前処理部３１を構成することで、図４に示す前処理部３１と同様の効果を得ることができる。なお、図６に示す前処理動力伝達ケース５０内に収容される伝達機構はチューン伝達機構である。
【００３４】
また、前述した実施の形態では、図３に示すように、回転軸ケース１１に天場処理部２１、前処理部３１及び整畦部４１を一体的に取り付けてなる作業部２０を有した畦塗り機１を示したが、図４に示すように、天場処理部２１を省略して、回転軸ケース１１に前処理部３１及び整畦部４１を一体的に取り付けた作業部２０を有した畦塗り機であってもよい。
【００３５】
さらに、前述した実施の形態では、図２（ｂ）に示すように、作業部２０は左右方向に旋回道自在なオフセットフレーム５の後端部に回動自在に設けられている場合を示したが、これに限るものではなく、左右方向に旋回動不能な畦塗り機本体部（図示せず）に一体化された作業部２０を、畦塗り機本体部の一方側のオフセット位置と、この位置とは畦塗り機本体部に対して反対側のオフセット位置に移動可能に取り付けるようにしてもよい。
【００３６】
【発明の効果】
以上説明したように、本発明に係わる畦塗り機によれば、回転軸ケース、前処理動力伝達ケース及び整畦動力伝達ケースを一体的に形成することで、前処理部を支持する部分と前処理部に駆動力を伝達する部分を近接した位置に配置することができ、また整畦部を支持する部分と整畦部に駆動力を伝達する部分を近接した位置に配置することができる。このため、畦塗り機の構造を簡略化して小型化することができる。また、回転軸ケース内に回転軸が収容され、前処理動力伝達ケース内に前処理動力伝達機構が収容され、整畦動力伝達ケース内に整畦動力伝達機構が収容されるので、畦塗り機による畦塗り作業時において、土が回転軸、前処理動力伝達機構及び整畦動力伝達機構に付着することはない。このため、走行機体から回転軸に伝達される駆動力が前処理部及び整畦部に伝達されるまでの間において、この駆動力が小さくなる事態を未然に防止することができる。さらに、前処理部の回転中心軸を平面視において整畦部の回転中心軸と交差する方向に且つ非直交する方向に延ばすことで、前処理部により土盛りされる土の流れの方向を整畦部側にすることができる。このため、整畦部に供給される土の流れがスムースになり、前処理部から旧畦上に供給される土を効率的に旧畦上に塗り付けることができる。
【００３７】
また、本発明に係わる畦塗り機によれば、オフセットフレームの後端部に作業部を水平方向に回動自在に設け、作業部は、請求項１に記載の回転軸ケースに一体的に形成された請求項１に記載の前処理動力伝達ケースに接続された請求項１から３のいずれかに前処理部と、回転軸ケースに一体的に形成された請求項１に記載の整畦動力伝達ケースに接続された請求項１に記載の整畦部を有してなることで、前処理部及び整畦部を支持する部分とこれらに動力を伝達する部分を近接位置に配置することができ、オフセットフレーム及び作業部を有してなる畦塗り機の構造を簡略化して小型化することができる。また前処理部及び整畦部に動力を伝達する伝動機構が前処理動力伝達ケース及び整畦動力伝達ケース内に収容されるので、畦塗り作業時の土が伝達機構に付着することはなく、走行機体から回転軸に伝達される駆動力が前処理部及び整畦部に伝達されるまでの間において、この駆動力が小さくなる事態を未然に防止することができ、また各伝動機構が障害物等に接触して損傷する虞を防止することができる。さらに、前処理部の回転中心軸を平面視において整畦部の回転中心軸と交差する方向に延ばすことで、整畦部に供給される土の流れがスムースになり、前処理部から旧畦上に供給される土を効率的に旧畦上に塗り付けることができる。

Etc. are scraped off and thrown into the field. Then, as shown in FIG. 5, the inner slope Uf of the old ridge U0 is cut from the upper part to the lower part by the preprocessing unit 31, and the cut soil is old along the rotational movement of the preprocessing unit 31. After moving from the lower part of the ridge U0 to the side that is once separated, the soil is moved upward, and the further cut soil is guided by the pretreatment cover 35 and supplied from the position above the old ridge U0 to the upper part of the old ridge U0.

For this reason, the structure of the coater can be simplified and reduced in size. Further, the rotary shaft is accommodated in the rotary shaft case, the pretreatment power transmission mechanism is accommodated in the pretreatment power transmission case, and the trimming power transmission mechanism is accommodated in the trimming power transmission case. At the time of the mortar coating operation, the soil does not adhere to the rotating shaft, the pretreatment power transmission mechanism, and the trimming power transmission mechanism. For this reason, it is possible to prevent a situation in which the driving force is reduced before the driving force transmitted from the traveling machine body to the rotating shaft is transmitted to the preprocessing unit and the trimming unit. Furthermore, by extending the rotation center axis of the pretreatment unit in a direction intersecting with the rotation center axis of the trimming unit in a plan view and in a non-orthogonal direction, the direction of the soil flow piled up by the pretreatment unit is trimmed.
