そして、シリンダ本体96の基端部が畦形成体支持体32の耕耘深さ調整用シリンダ取付部54に水平な左右方向の軸99を介して回動可能に取り付けられている。また、ロッド97の先端部がシリンダ取付部材94の上端部に固着されている。   The base end portion of the cylinder body 96 is rotatably attached to the tillage depth adjusting cylinder attachment portion 54 of the ridge forming body support 32 via a horizontal shaft 99 in the horizontal direction. Further, the tip of the rod 97 is fixed to the upper end of the cylinder mounting member 94.

このため、盛土体12の耕耘深さの調整の際には、耕耘深さ調整用シリンダ36の伸縮に応じて(耕耘深さ調整手段の作動に応じて)、上側回動体81および下側回動体82が畦形成体支持体32に対して軸84,86の軸芯を通る水平軸線(回動支点)Xを中心として上下回動し、これにより、盛土体支持体31が盛土体12と一体となって畦形成体支持体32に対して水平軸線Xを中心として上下平行移動する。   For this reason, when the tilling depth of the embankment body 12 is adjusted, according to the expansion and contraction of the tillage depth adjusting cylinder 36 (according to the operation of the tilling depth adjusting means), the upper rotating body 81 and the lower turn The moving body 82 rotates up and down around the horizontal axis (rotation fulcrum) X passing through the axis of the shafts 84 and 86 with respect to the ridge forming body support body 32, whereby the embankment body support body 31 and the embankment body 12 As a unit, it moves up and down in parallel around the horizontal axis X with respect to the heel-forming body support 32.

向き調整用シリンダ37は、シリンダ本体101と、このシリンダ本体101の先端面開口101aから突出するロッド102とを有している。ロッド102のシリンダ本体101内に位置する基端部にはピストン103が固着され、このピストン103はシリンダ本体101内で移動可能となっている。   The orientation adjusting cylinder 37 includes a cylinder body 101 and a rod 102 that protrudes from a front end surface opening 101a of the cylinder body 101. A piston 103 is fixed to a base end portion of the rod 102 located in the cylinder body 101, and the piston 103 is movable in the cylinder body 101.

そして、シリンダ本体101の基端部が畦形成体支持体32の向き調整用シリンダ取付部55にボールジョイント104を介して全方向に回動可能に取り付けられている。また、ロッド102の先端部が盛土体支持体31のシリンダ取付部75の上面側にボールジョイント105を介して全方向に回動可能に取り付けられている。   The base end portion of the cylinder main body 101 is attached to the orientation adjusting cylinder attachment portion 55 of the rod forming body support 32 via the ball joint 104 so as to be rotatable in all directions. Further, the tip of the rod 102 is attached to the upper surface side of the cylinder mounting portion 75 of the embankment support 31 through a ball joint 105 so as to be rotatable in all directions.

このため、盛土体12の向きの調整の際には、向き調整用シリンダ37の伸縮に応じて(向き調整手段の作動に応じて)、盛土体支持体31が上側回動体81および下側回動体82に対してボールジョイント83,85の中心を通る鉛直軸線Yを中心として左右回動する。つまり、盛土体支持体31が盛土体12と一体となって畦形成体支持体32に対して鉛直軸線Yを中心として左右回動する。なお、各シリンダ21,22,36,37は、トラクタ2に乗った作業者による遠隔操作によって伸縮可能となっている。   For this reason, when adjusting the direction of the embankment body 12, the embankment body support 31 is connected to the upper rotating body 81 and the lower rotation according to the expansion and contraction of the orientation adjusting cylinder 37 (according to the operation of the orientation adjusting means). With respect to the moving body 82, it rotates right and left around a vertical axis Y passing through the centers of the ball joints 83 and 85. That is, the embankment body support 31 is integrated with the embankment body 12 and pivots left and right around the vertical axis Y with respect to the ridge forming body support body 32. Each cylinder 21, 22, 36, 37 can be expanded and contracted by a remote operation by an operator riding on the tractor 2.

次に、畦塗り機1の作用等を図面を説明する。   Next, the operation and the like of the wrinkle coater 1 will be described with reference to the drawings.

畦塗り機1をトラクタ2の後部に連結してトラクタ2の前進走行により元畦に沿って前方に移動させると、上面削り体14にて元畦の畦上面が削られて雑草等が除去され、この上面削り体14の後方では盛土体12にて田面および元畦の土が耕耘されて元畦上に盛り上げられ、この盛土体12の後方では畦形成体13にて盛土が締め固められて新畦が形成される。   When the hull coater 1 is connected to the rear part of the tractor 2 and is moved forward along the main fence by the forward traveling of the tractor 2, the upper face of the main hull is cut by the upper face scraping body 14 to remove weeds and the like. Behind this top surface cutting body 14, the paddy field and the Marshal soil are cultivated by the embankment body 12, and the soil is raised on the marshal basin. A cocoon is formed.

ここで、例えば田面の土質や元畦の土質等の作業条件に合わせて、所望の盛土量が得られるようにするために、図3に示す状態(基準状態)に比べて、盛土体12の耕耘深さを浅くする場合、作業者は、操作ボックスの操作部を操作し、耕耘深さ調整用シリンダ36を縮ませる。   Here, for example, in order to obtain a desired amount of embankment according to the work conditions such as the soil quality of the paddy field and the soil quality of the marshal, the embankment body 12 is compared with the state (reference state) shown in FIG. When the tilling depth is decreased, the operator operates the operation portion of the operation box to contract the tilling depth adjusting cylinder 36.

耕耘深さ調整用シリンダ36が縮むと、図4に示すように、上側回動体81および下側回動体82が、互いに平行なまま、畦形成体支持体32に対して左右水平方向の水平軸線(軸84,86)Xを中心として上方に回動する。   When the tillage depth adjusting cylinder 36 is contracted, as shown in FIG. 4, the horizontal axis of the horizontal horizontal direction with respect to the cocoon forming body support 32 while the upper rotary body 81 and the lower rotary body 82 remain parallel to each other. (Axis 84, 86) Rotate upward about X.

両回動体81,82が上方に回動すると、盛土体支持体31が、盛土体12と一体となって畦形成体支持体32に対して水平軸線Xを中心として円弧を描くように上方に平行移動する。その結果、盛土体12の向きが上下に傾くことなく盛土体12の作業姿勢が一定に維持されたまま、盛土体12の耕耘深さが浅くなる。   When both the rotating bodies 81 and 82 are rotated upward, the embankment support 31 is integrated with the embankment 12 so as to draw an arc around the horizontal axis X with respect to the ridge formation support 32. Translate. As a result, the tilling depth of the embankment body 12 becomes shallow while the working posture of the embankment body 12 is maintained constant without the orientation of the embankment body 12 being tilted up and down.

また逆に、図3に示す状態に比べて、盛土体12の耕耘深さを深くする場合、作業者は、操作ボックスの操作部を操作し、耕耘深さ調整用シリンダ36を伸ばす。   On the contrary, when the tilling depth of the embankment body 12 is deepened as compared with the state shown in FIG. 3, the operator operates the operation portion of the operation box and extends the tillage depth adjusting cylinder 36.

耕耘深さ調整用シリンダ36が伸びると、図5に示すように、上側回動体81および下側回動体82が、互いに平行なまま、畦形成体支持体32に対して水平軸線(軸84,86)Xを中心として下方に回動する。   When the tillage depth adjusting cylinder 36 is extended, as shown in FIG. 5, the upper rotating body 81 and the lower rotating body 82 remain parallel to each other with respect to the heel forming body support body 32, with the horizontal axis (axis 84, 86) Rotate downward about X.

両回動体81,82が下方に回動すると、盛土体支持体31が、盛土体12と一体となって畦形成体支持体32に対して水平軸線Xを中心として円弧を描くように下方に平行移動する。その結果、盛土体12の向きが上下に傾くことなく盛土体12の作業姿勢が一定に維持されたまま、盛土体12の耕耘深さが深くなる。   When both the rotating bodies 81 and 82 rotate downward, the embankment support 31 is integrated with the embankment 12 so as to draw an arc around the horizontal axis X with respect to the ridge formation support 32. Translate. As a result, the tilling depth of the embankment body 12 is deepened while the working posture of the embankment body 12 is maintained constant without the orientation of the embankment body 12 being tilted up and down.

なお、盛土体12の耕耘深さを最も深くした場合と最も浅くした場合との高低差は、例えば約150mmである。   In addition, the height difference between the case where the tilling depth of the embankment body 12 is the deepest and the case where it is the shallowest is about 150 mm, for example.

また、例えば図6に示すように、元畦が田面側である左側に少し曲がっていた場合、図2に示す状態(基準状態)のように、盛土体12の向きが真直ぐ前方を向いた状態、つまり平面視で盛土体12の回転軸65の軸方向が前後方向に一致した状態のまま、畦塗り作業を行うと、盛土体12が元畦にくいこみ、盛土体12による盛土量が必要以上に多くなる。   In addition, for example, as shown in FIG. 6, when the marshal is slightly bent to the left side which is the rice field side, the state of the embankment body 12 faces straight forward as in the state shown in FIG. 2 (reference state). In other words, if the filling operation is performed while the axial direction of the rotary shaft 65 of the embankment body 12 is aligned in the front-rear direction in plan view, the embankment body 12 is difficult to marshal and the amount of embankment by the embankment body 12 is more than necessary. To be more.

このため、作業者は、所望の盛土量が得られるよう、操作ボックスの操作部を操作し、向き調整用シリンダ37を縮ませる。   For this reason, the operator operates the operation part of the operation box so as to obtain the desired embankment amount, and contracts the orientation adjusting cylinder 37.

向き調整用シリンダ37が縮むと、図6に示されるように、盛土体支持体31が、上側回動体81および下側回動体82に対して上下方向の鉛直軸線Yを中心として左方向に回動する。つまり、盛土体支持体31が、盛土体12と一体となって畦形成体支持体32に対して鉛直軸線Yを中心として左方向に回動する。その結果、盛土体12の耕耘深さが一定に維持されたまま、盛土体12の向きが真直ぐ前方を向いた状態から左斜め前方を向いた状態となる。つまり盛土体12がやや左側に首を振る。   When the orientation adjusting cylinder 37 is contracted, the embankment support 31 rotates leftward about the vertical axis Y in the vertical direction with respect to the upper rotating body 81 and the lower rotating body 82 as shown in FIG. Move. In other words, the embankment support 31 rotates integrally with the embankment 12 in the left direction about the vertical axis Y with respect to the ridge-form support 32. As a result, while the tilling depth of the embankment body 12 is maintained constant, the orientation of the embankment body 12 is changed from a state of facing straight forward to a diagonally forward left direction. That is, the embankment body 12 swings its head slightly to the left.

また、例えば図7に示すように、元畦が田面側とは反対側である右側に少し曲がっていた場合、図2に示す状態(基準状態)のままで畦塗り作業を行うと、盛土体12が元畦から離れ、盛土体12による盛土量が不足する。   Further, for example, as shown in FIG. 7, when the marsket is bent slightly to the right side, which is the opposite side to the rice field side, when the padding operation is performed in the state (reference state) shown in FIG. 12 is away from the Marshal, and the embankment volume by the embankment body 12 is insufficient.

このため、作業者は、所望の盛土量が得られるよう、操作ボックスの操作部を操作し、向き調整用シリンダ37を伸ばす。   For this reason, the operator operates the operation portion of the operation box and extends the orientation adjusting cylinder 37 so that a desired amount of banking is obtained.

向き調整用シリンダ37が伸びると、図7に示されるように、盛土体支持体31が、上側回動体81および下側回動体82に対して上下方向の鉛直軸線Yを中心として右方向に回動する。つまり、盛土体支持体31が、盛土体12と一体となって畦形成体支持体32に対して鉛直軸線Yを中心として右方向に回動する。その結果、盛土体12の耕耘深さが一定に維持されたまま、盛土体12の向きが真直ぐ前方を向いた状態から右斜め前方を向いた状態となる。つまり盛土体12がやや右側に首を振る。   When the orientation adjustment cylinder 37 is extended, the embankment support 31 rotates clockwise with respect to the vertical axis Y in the vertical direction with respect to the upper rotating body 81 and the lower rotating body 82, as shown in FIG. Move. In other words, the embankment body support 31 is integrally rotated with the embankment body 12 and rotated rightward with respect to the ridge forming body support body 32 about the vertical axis Y. As a result, while the tilling depth of the embankment body 12 is maintained constant, the direction of the embankment body 12 is changed from a state of facing straight forward to a state of facing right obliquely forward. That is, the embankment body 12 swings its head slightly to the right.

なお、基準状態からの盛土体支持体31の鉛直軸線Yを中心とする回動角度θは、最大で例えば約25度である。   Note that the rotation angle θ around the vertical axis Y of the embankment support 31 from the reference state is, for example, about 25 degrees at the maximum.

そして、このような畦塗り機1によれば、盛土体支持体31の畦形成体支持体32に対する上下動により盛土体12の耕耘深さを調整できるばかりでなく、盛土体支持体31の畦形成体支持体32に対する左右回動により盛土体12の向きを調整できるため、作業条件に拘らず、所望の盛土量を得ることが可能となり、よって、適切な畦塗り作業ができる。   According to such a pad coater 1, not only the tilling depth of the embankment body 12 can be adjusted by the vertical movement of the embankment body support 31 with respect to the cocoon formation body support 32, but also the eaves of the embankment body support 31 can be adjusted. Since the orientation of the embankment body 12 can be adjusted by rotating left and right with respect to the forming body support 32, it is possible to obtain a desired embankment amount regardless of the work conditions, and thus an appropriate filling operation can be performed.

また、耕耘深さ調整用シリンダ36を利用して盛土体12の耕耘深さを適切に調整でき、かつ、向き調整用シリンダ37を利用して盛土体12の向きを適切に調整できる。   Further, the tilling depth adjusting cylinder 36 can be used to appropriately adjust the tilling depth of the embankment body 12, and the orientation adjusting cylinder 37 can be used to appropriately adjust the orientation of the embankment body 12.

さらに、耕耘深さ調整用シリンダ36の伸縮に応じて上側回動体81および下側回動体82が畦形成体支持体32に対して軸84,86を通る水平軸線Xを中心として上下回動するため、耕耘深さ調整用シリンダ36を利用して盛土体12の耕耘深さをより一層適切に調整でき、向き調整用シリンダ37の伸縮に応じて盛土体支持体31が上側回動体81および下側回動体82に対して球面軸受であるボールジョイント83,85を通る鉛直軸線Yを中心として左右回動するため、向き調整用シリンダ37を利用して盛土体12の向きをより一層適切に調整できる。   Further, the upper rotating body 81 and the lower rotating body 82 rotate up and down around the horizontal axis line X passing through the shafts 84 and 86 with respect to the rod forming body support 32 in accordance with the expansion and contraction of the tillage depth adjusting cylinder 36. Therefore, the tillage depth adjustment cylinder 36 can be used to adjust the tillage depth of the embankment body 12 more appropriately, and the embankment body support 31 can be adjusted according to the expansion and contraction of the orientation adjustment cylinder 37. Since the left and right pivots about the vertical axis Y that passes through the ball joints 83 and 85 that are spherical bearings with respect to the side pivoting body 82, the orientation of the embankment body 12 is more appropriately adjusted using the orientation adjusting cylinder 37. it can.

また、耕耘深さ調整用シリンダ(伸縮体)36および向き調整用シリンダ(伸縮体)37はいずれも電動油圧シリンダ等の流体圧シリンダにて構成されているため、作業者が手動で伸縮体を直接的に伸縮させる構成等に比べて、盛土体12の耕耘深さおよび向きを容易に調整できる。   Further, since the tillage depth adjustment cylinder (extension body) 36 and the orientation adjustment cylinder (extension body) 37 are both composed of a hydraulic cylinder such as an electric hydraulic cylinder, the operator manually attaches the extension body. Compared to a configuration that directly expands and contracts, the tilling depth and orientation of the embankment body 12 can be easily adjusted.

なお、畦塗り機1が有する調整手段である伸縮体(耕耘深さ調整用伸縮体、向き調整用伸縮体)は、電動油圧シリンダ等の流体圧シリンダにて構成されたものには限定されず、例えば作業者が手動でハンドルを回動操作することで伸縮するようなねじ式の伸縮ロッドにて構成されたもの等でもよい。   In addition, the expansion / contraction body (cultivation depth adjustment expansion / contraction body, orientation adjustment expansion / contraction body) which is the adjusting means of the paddy coater 1 is not limited to one configured by a fluid pressure cylinder such as an electric hydraulic cylinder. For example, it may be configured by a screw-type telescopic rod that expands and contracts by an operator manually turning the handle.

また、耕耘深さ調整用シリンダ36の縮み動作で盛土体12が上動しかつ耕耘深さ調整用シリンダ36の伸び動作で盛土体12が下動する構成には限定されず、例えば耕耘深さ調整用シリンダ36の縮み動作で盛土体12が下動しかつ耕耘深さ調整用シリンダ36の伸び動作で盛土体12が上動する構成でもよい。   Further, the embankment body 12 is not limited to the configuration in which the embankment body 12 moves up by the contraction operation of the tillage depth adjustment cylinder 36 and the embankment body 12 moves down by the extension operation of the tillage depth adjustment cylinder 36. The embankment body 12 may be moved downward by the contracting operation of the adjusting cylinder 36 and the embankment body 12 may be moved up by the extending operation of the tillage depth adjusting cylinder 36.
