【発明が解決しようとする課題】
従来、実開平３−１２２６０３号公報、または特開平８−１４９９０２号後方に示す如く、トラクタ後側に畦塗機本体ケースを装設させ、トラクタの左右いずれかに畦塗機本体ケースを水平回転させて方向転換させ、トラクタの前進作業によって塗り残した畦終端を、後進作業によって塗ることにより、手塗り作業を省くことができる技術がある。しかし乍ら、前記従来技術は、トラクタに装設させる台フレームに上下支点軸を設け、上下支点軸の間に畦塗機本体ケースを挾むように設けていたから、畦塗機本体ケース上面側の強度を大きくする必要があり、畦塗機本体ケースの構造の簡略化並びに組立分解作業性の向上などを容易に行い得ない不具合がある。また、台フレームにフックまたはピンを設けて畦塗機本体ケースを固定させていたから、畦塗作業によって大きな振動が発生し易い畦塗機本体ケースの防振を前記フックまたはピンによって行う必要があり、前記フック構造の簡略化を容易に行い得ず、またガタが生じるフックまたはピンの連結だけでは支点軸部などを損傷させ易い不具合がある。また、トラクタのＰＴＯ駆動力を伝える軸を台フレームに設け、該軸を畦塗機本体ケースのＰＴＯ入力軸に係脱自在に連結させていたから、伝動構造脱着操作が必要となって畦塗機本体ケースの方向転換操作の簡略化を容易に行い得ない不具合がある。
【０００３】
【課題を解決するための手段】
然るに、本発明は、トラクタ（１）の後方左右両側に、元畦土を砕いて寄せる左右ロータリ爪（１０）（１１）よりなる左右土処理部を取付けると共に、該左右ロータリ爪（１０）（１１）よりなる左右土処理部の夫々の後側に、択一的に位置変更自在で、土を締固めて新畦を形成する整形ローラ（１２）よりなる整形部を取付け、トラクタ後側に装設させて畦を連続的に形成する畦塗装置において、前記左右ロータリ爪（１０）（１１）を左右ロータリカバー（２１）（２１）に内設させ、該左右ロータリカバー（２１）（２１）を、畦塗本体ケース（１５）に左右の伸縮シリンダ（２２）（２２）を介して昇降自在に連結させ、該畦塗本体ケース（１５）の後面に支点ケース（２３）を一体固定させ、該支点ケース（２３）に軸受（２４）を介して前記可動ケース（２５）を回転自在に取付け、該可動ケース（２５）に伝動ケース（２６）を一体固定させ、前記整形ローラ（１２）を該伝動ケース（２６）に回転自在に軸支させ、前記可動ケース（２５）と伝動ケース（２６）と整形ローラ（１２）を回転させて、左右ロータリ爪（１０）（１１）のいずれか一方の後側に整形ローラ（１２）を移動させ、入力軸（１７）の後端を支点ケース（２３）内に延設させ、正転及び逆転ベベルギヤ（２７）（２８）を入力軸（１７）上に固定させると共に、該正転及び逆転ベベルギヤ（２７）（２８）のいずれか一方に、択一的に噛合させる出力ベベルギヤ（２９）を可動ケース（２５）に軸支させ、トラクタの前進走行によって左塗り作業と右塗り作業の両方を行なえるように構成したので、トラクタのリンク機構に畦塗本体ケースを連結させ、該畦塗本体ケースに左右土処理部を取付け得、整形部だけを位置変更自在に取付けることによって整形部の方向転換構造及び伝動構造の簡略化並びに方向転換操作性の向上などを容易に図り得る。
それと共に、左塗り作業と右塗り作業のいずれかをトラクタの後進によって行うことにより作業者が後向き姿勢になる不具合をなくし得、運転し易いトラクタの前進走行により左塗りと右塗りの両方の作業を行えて作業性の向上を容易に図り得るものである。
