Description

本発明は、水田を区画する旧畦を畦塗り修復して新畦を形成する畦塗り機に関する。   The present invention relates to a cocoon coater that forms a new rice cake by repairing an old rice cake that partitions a paddy field.

旧畦を畦塗り修復する畦塗り作業は、旧畦の水漏れを防ぐとともに、旧畦の側面部の崩れた部分や旧畦の上部(以下、「天場部」と記す。)が踏圧されて凹んだ部分を平らに補修することを目的として行なわれるが、この畦塗り作業は労力を要することから、機械化された畦塗り機が開発されている(特許文献1、2参照)。   The painting process of painting and repairing the old fence prevents water leakage of the old fence, and stepping on the collapsed part of the side of the old fence and the upper part of the old fence (hereinafter referred to as “the heaven field”). Although this is done for the purpose of repairing the recessed parts flat, this glazing operation requires labor, and mechanized glazing machines have been developed (see Patent Documents 1 and 2).

特許文献1に記載の畦塗り機は、走行機体の後部に取り付けられる機枠に機枠進行方向に対して左右方向に移動自在な可動機枠が取り付けられ、この可動機枠に旧畦の天場部を切り崩す天場処理ロータ(文献内では前処理ロータリー6)、旧畦を切り崩して土盛りを行う前処理ロータ(文献内では盛土ロータリー4)及び盛られた土を切り崩された旧畦上に塗り付ける畦塗り体をそれぞれ配設して構成されている。天場処理ロータ、前処理ロータ及び畦塗り体は、機枠の進行方向に対して左右方向に延びる回転軸を備える。   In the wrinkle coater described in Patent Document 1, a movable machine frame that is movable in the horizontal direction with respect to the machine frame traveling direction is attached to a machine frame that is attached to the rear part of the traveling machine body. On top of a heaven-processed rotor (in the literature, pre-treatment rotary 6) that cuts off the field, a pre-treatment rotor (in the literature, fill-in rotary 4) that cuts the old culvert and fills the earth, and on the old culvert that has been crushed Each of the glazed bodies to be applied is arranged and configured. The heavenly processing rotor, the pretreatment rotor, and the glazed body include a rotation shaft that extends in the left-right direction with respect to the traveling direction of the machine frame.

可動機枠には、走行機体から伝達された動力を天場処理ロータ、前処理ロータ及び畦塗り体のそれぞれに伝達するための動力伝達機構を内蔵した第1から第4の伝動ケースが設けられている。第1の伝動ケースは可動機枠の前側に配置されて左右方向に延び、第2の伝動ケースは第1の伝動ケースの右側端部に連結されて前側に延びる。第3の伝動ケースは第2の伝動ケースの前側端部に連結されて前側に延びる。第4の伝動ケースは第1の伝動ケースの後方側に第1の伝動ケースに沿って配設されて左右方向に延びる。第3の伝動ケースの前側端部に天場処理ロータの回転軸が回転可能に連結され、第2の伝動ケースと第3の伝動ケースの連結部分に前処理ロータの回転軸が回転可能に連結されている。第4の伝動ケースの右側端部に畦塗り体の回転軸が回転可能に連結されている。   The movable machine frame is provided with first to fourth transmission cases incorporating a power transmission mechanism for transmitting the power transmitted from the traveling machine body to each of the heavenly processing rotor, the pretreatment rotor, and the glazed body. ing. The first transmission case is disposed on the front side of the movable machine frame and extends in the left-right direction, and the second transmission case is connected to the right end portion of the first transmission case and extends on the front side. The third transmission case is connected to the front end of the second transmission case and extends to the front side. The fourth transmission case is disposed along the first transmission case on the rear side of the first transmission case and extends in the left-right direction. The rotary shaft of the heavenly processing rotor is rotatably connected to the front end portion of the third transmission case, and the rotary shaft of the pretreatment rotor is rotatably connected to the connecting portion of the second transmission case and the third transmission case. Has been. The rotating shaft of the glazed body is rotatably connected to the right end portion of the fourth transmission case.

一方、特許文献2に記載の畦塗り機は、天場処理ロータ及び前処理ロータの回転軸が旧畦の延びる方向に略平行になるように配置される点で特許文献1記載の畦塗り機と相違する。   On the other hand, the brush coating machine described in Patent Document 2 is that the rotational axes of the heavenly processing rotor and the preprocessing rotor are arranged so as to be substantially parallel to the direction in which the old hammer extends. Is different.

特開2000−83407号公報JP 2000-83407 A 特開2002−325502号公報JP 2002-325502 A

ここで、旧畦の天場部を切り崩す天場処理作業は、旧畦の状態によっては不要な場合がある。このような場合、天場処理ロータを取り外すことができれば、畦塗り機が軽量化されて取り扱いが便利となるので、天場処理作業の必要性に応じて天場処理ロータを着脱可能な畦塗り機が望まれている。   Here, the celestial processing work for breaking up the heaven field part of the old fence may be unnecessary depending on the state of the old fence. In such a case, if the celestial processing rotor can be removed, the glazing machine will be lighter and easier to handle. A machine is desired.

また特許文献1記載の天場処理ロータは、第3の伝動ケースに内蔵され動力伝達機構と、この機構と天場処理ロータとの間に連結された他の動力伝達機構とを介して動力伝達されるようになっている。特許文献2記載の天場処理ロータは複数のチェーン伝動機構を介して動力伝達されるようになっている。つまり、従来の天場処理ロータは、複数の動力伝達機構を介して動力伝達される。このため、畦塗り機全体が大型化するとともに、重量が重くなるという問題がある。   Further, the celestial processing rotor described in Patent Document 1 is configured to transmit power via a power transmission mechanism built in the third transmission case and another power transmission mechanism connected between this mechanism and the celestial processing rotor. It has come to be. The heavenly-processed rotor described in Patent Document 2 is configured to transmit power through a plurality of chain transmission mechanisms. That is, the conventional celestial processing rotor transmits power through a plurality of power transmission mechanisms. For this reason, there exists a problem that the whole coating machine enlarges and a weight becomes heavy.

さらに特許文献1記載の天場処理ロータの回転軸は旧畦の延びる方向に対して左右方向に略直交する方向に延びているので、天場処理ロータに設けられた天場処理爪は旧畦の延びる方向と略平行に延びる。このため、天場処理爪によって削られた旧畦の天場部の土はその殆どが天場部上に残り、水田に落下するのは僅かである。このため、天場部には天場処理ロータによって削られた土と前処理ロータから供給される土が堆積することになり、畦塗り体によって整畦される新畦の高さは旧畦のそれより高くなり、新畦の高さを旧畦の高さと同程度や低くしたりする調整がし難いという問題がある。また、特許文献2記載の天場処理ロータは回転軸が旧畦の延びる方向に略平行に配置されるので、天場処理爪は天場処理ロータの進行方向に対して略直交する方向になる。このため、天場処理ロータが回転動しながら進行方向前側に移動した場合、天場処理爪の裏面側(天場処理ロータの進行方向前側)には、天場部の土との接触による大きな負荷が作用して、天場処理爪を介して天場処理ロータに振動を発生させるという問題がある。   Furthermore, since the rotation axis of the heaven processing rotor described in Patent Document 1 extends in a direction substantially orthogonal to the left-right direction with respect to the direction in which the old iron extends, the heaven processing claws provided in the heaven processing rotor are It extends substantially parallel to the extending direction of. For this reason, most of the soil in the heaven part of the old slab shaved by the heaven treatment claws remains on the heaven part, and it rarely falls to the paddy field. For this reason, the soil cut by the heaven processing rotor and the soil supplied from the pretreatment rotor accumulate in the heaven field, and the height of the new cocoon arranged by the padding body is There is a problem that it is difficult to adjust the height of the Xinjiang to be the same as or lower than that of the old wall. Moreover, since the rotation axis of the celestial processing rotor described in Patent Document 2 is disposed substantially parallel to the direction in which the old iron extends, the celestial processing claw is in a direction substantially orthogonal to the traveling direction of the celestial processing rotor. . For this reason, when the celestial processing rotor rotates and moves to the front side in the traveling direction, the back side of the celestial processing claw (the front side in the traveling direction of the celestial processing rotor) There is a problem that a load acts and vibrations are generated in the heaven processing rotor via the heaven processing claws.

本発明は、このような問題に鑑みてなされたものであり、天場処理作業が不要なときに天場処理ロータを取り外すことができ、畦塗り機の小型軽量化が可能であり、新畦の高さ調整をし易くし、天場処理ロータに発生する振動を抑制可能な畦塗り機を提供することを目的とする。   The present invention has been made in view of such a problem, and can remove the heaven processing rotor when the heaven processing operation is unnecessary, and can reduce the size and weight of the glazing machine. It is an object of the present invention to provide a wrinkle coater that can easily adjust the height of the rotor and suppress vibrations generated in the celestial processing rotor.

上記目的を達成するために本発明の畦塗り機は、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、旧畦の上部を切り崩す天場処理部、旧畦を切り崩して土盛りを行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た畦塗り機において、天場処理部は、その回転中心軸が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て設けられることを特徴とする。   In order to achieve the above-mentioned object, the plastering machine of the present invention is mounted on a traveling machine body, is disposed at a position offset laterally with respect to the traveling position of the traveling machine body, and cuts the upper part of the old fence. , In the slag coater equipped with a pre-processing unit that cuts and fills the old paddle and a trimming unit that applies the piled soil on the cut old paddle, the center of rotation of the heavenly processing unit is a plan view. In FIG. 2, the first and second trimming portions are provided so as to extend in a direction crossing the rotation center axis of the trimming portion.

この発明によれば、天場処理部を、その回転中心軸が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ように設けることで、整畦部の回転中心軸を旧畦の延びる方向に対して直交する方向に配置すると、天場処理部の回転中心軸は旧畦の延びる方向に対して斜め方向に配置される。この状態で天場処理部による天場処理作業が行われると、天場処理部によって削られた旧畦上部の土の一部は、水田側に飛ばされて旧畦の際の水田内に落下する。このため、天場処理部によって削られた土の全てがそのまま天場部に堆積して残ることはなく、畦塗り体によって整畦される新畦の高さを旧畦のそれと略同じにしたり低くめにしたりするような、新畦の高さ調整をし易くすることができる。また天場処理部が進行方向前側に移動する場合、天場処理部の前進移動にともなう天場処理部の天場処理爪にかかる抵抗は、天場処理部の回転中心軸が旧畦の延びる方向と同方向にある場合と比較して、小さくなる。これは、回転中心軸から放射状に延びる天場処理爪の背面部(進行方向前側の天場処理爪の側面部)に受ける力のうちの直交成分の力が小さくなると考えられるからである。このため、天場処理爪を介して天場処理部に発生する振動を抑制することができる。   According to the present invention, the celestial processing unit is provided so that its rotation center axis extends in a direction intersecting with the rotation center axis of the trimming unit in plan view, so that the rotation center axis of the trimming unit is If it arrange | positions in the direction orthogonal to the extending direction, the rotation center axis | shaft of a celestial process part will be arrange | positioned in the diagonal direction with respect to the extending direction of an old iron. When the heaven field processing work is performed by the heaven field processing unit in this state, a part of the soil above the old paddle cut by the heaven field processing unit is blown to the paddy field and falls into the paddy field at the time of the old paddy field To do. For this reason, all of the soil cut by the heaven field processing unit does not remain deposited on the heaven field, and the height of the new culm arranged by the lacquered body is almost the same as that of the old one. It is possible to make it easier to adjust the height of the Xinjiang, such as lowering. In addition, when the celestial processing unit moves to the front side in the traveling direction, the resistance applied to the celestial processing claw of the celestial processing unit accompanying the forward movement of the celestial processing unit is such that the rotation center axis of the celestial processing unit extends the old iron Compared to the case of being in the same direction as the direction, it becomes smaller. This is because it is considered that the force of the orthogonal component of the force received on the back surface portion (the side surface portion of the celestial processing claw on the front side in the traveling direction) of the celestial processing claw extending radially from the rotation center axis is reduced. For this reason, the vibration which generate | occur | produces in a heaven processing part via a heaven processing nail | claw can be suppressed.

また本発明は、前処理部の回転中心軸が、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て設けられ、天場処理部を、前処理部の進行方向前方に設けたことを特徴とする。   In the present invention, the rotation center axis of the preprocessing unit is provided so as to extend in a direction intersecting with the rotation center axis of the trimming unit in plan view, and the heaven processing unit is provided in front of the preprocessing unit in the traveling direction. It is characterized by that.

この発明によれば、前処理部をその回転中心軸が整畦部の回転中心軸と交差する方向に延びるように設け、天場処理部を前処理部の進行方向前方に設けることにより、天場処理部の回転中心軸と前処理部の回転中心軸とを略平行に配置すると、前処理部及び天場処理部の近接配置が可能となり、畦塗り機全体を小型化することができる。   According to the present invention, the pretreatment unit is provided so that the rotation center axis thereof extends in a direction intersecting the rotation center axis of the adjusting unit, and the ceiling processing unit is provided in front of the pretreatment unit in the traveling direction. When the rotation center axis of the field processing unit and the rotation center axis of the preprocessing unit are arranged substantially in parallel, the preprocessing unit and the heaven field processing unit can be arranged close to each other, and the entire coater can be downsized.

また本発明は、天場処理部が、前処理部に連結された動力伝達機構(例えば、実施形態における天場側動力伝達機構56)を介して動力伝達されることを特徴とする。   In addition, the present invention is characterized in that the heaven processing unit transmits power via a power transmission mechanism (for example, the heaven-side power transmission mechanism 56 in the embodiment) connected to the preprocessing unit.

この発明によれば、天場処理部は前処理部に連結された動力伝達機構を介して動力伝達されることにより、前処理部に伝達された動力を、動力伝達機構を介して天場処理部に伝達することができる。このため、前処理部及び天場処理部を近接配置した状態で前処理部に伝達された動力を天場処理部に伝達することができる。その結果、動力伝達機構の長さを短縮化することができ、畦塗り機全体を軽量化することができる。   According to the present invention, the heaven field processing unit transmits power through the power transmission mechanism connected to the preprocessing unit, so that the power transmitted to the preprocessing unit is transmitted through the power transmission mechanism. Can be transmitted to the part. For this reason, the motive power transmitted to the pre-processing unit in a state where the pre-processing unit and the celestial processing unit are arranged close to each other can be transmitted to the celestial processing unit. As a result, the length of the power transmission mechanism can be shortened, and the entire coater can be reduced in weight.

さらに本発明は、天場処理部が前処理部に対して上下動可能に設けられることを特徴とする。   Furthermore, the present invention is characterized in that the heaven processing unit is provided so as to be movable up and down with respect to the preprocessing unit.

この発明によれば、天場処理部を前処理部に対して上下動可能にすることで、天場処理部によって旧畦上部を削るときに、石等の固い物に天場処理部の天場処理爪が当接すると、天場処理部自体が上方へ移動して規制された天場処理爪の回転動作を許容する。このため、天場処理部による天場処理作業が中断する事態を未然に防止することができる。   According to the present invention, by allowing the heaven processing unit to move up and down with respect to the preprocessing unit, when the upper part of the old fence is shaved by the heaven processing unit, the ceiling of the heaven processing unit is applied to a hard object such as a stone. When the field processing claw comes into contact, the heaven processing unit itself moves upward to allow the restricted rotation of the heaven processing claw. For this reason, the situation where the heaven processing operation by the heaven processing unit is interrupted can be prevented.

また本発明は、天場処理部が前処理部に対して着脱可能に設けられたことを特徴とする。   In addition, the present invention is characterized in that the heaven processing unit is detachably provided to the preprocessing unit.

この発明によれば、天場処理部を前処理部に対して着脱可能に設けることにより、天場処理作業が必要なときに天場処理部を前処理部に装着し、天場処理作業が不要なときに天場処理部を前処理部から脱着することができる。このため、畦塗り作業の内容に応じて天場処理部を装着したり脱着したりすることができる。   According to the present invention, by providing the heaven processing section so as to be detachable from the preprocessing section, the heaven processing section is attached to the preprocessing section when the heaven processing operation is required, When not required, the heaven field processing unit can be detached from the preprocessing unit. For this reason, a heaven processing part can be mounted | worn or removed according to the content of the haze coating operation | work.

本発明に係わる畦塗り機によれば、天場処理部及び前処理部を、その回転中心軸が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ようにして設け、天場処理部を前処理部の進行方向前方に設け、天場処理部を前処理部に対して着脱可能に設けることにより、畦塗り作業内容に応じて天場処理部を装着したり脱着したりすることができ、畦塗り機の小型軽量化が可能であり、新畦の高さ調整をし易くし、天場処理部に発生する振動を抑制することができる。   According to the wrinkle coater according to the present invention, the heaven processing unit and the preprocessing unit are provided such that the rotation center axis thereof extends in a direction intersecting with the rotation center axis of the trimming unit in plan view, Attaching and detaching the heaven processing unit according to the details of the haze coating work by providing the front part in the forward direction of the pre-processing unit and detaching the heaven processing unit from the pre-processing unit Thus, it is possible to reduce the size and weight of the haze coater, to easily adjust the height of the new haze, and to suppress the vibration generated in the heaven field processing unit.

以下、本発明に係わる畦塗り機の好ましい実施の形態を図1から図4に基づいて説明する。本実施の形態は、走行機体90の前進動に応じて畦塗り作業を行なう畦塗り機を例にして説明する。なお、説明の都合上、図1(平面図)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。   DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a coater according to the present invention will be described below with reference to FIGS. The present embodiment will be described with reference to an example of a scissor machine that performs a smearing operation in accordance with the forward movement of the traveling machine body 90. For convenience of explanation, the directions of arrows shown in FIG. 1 (plan view) will be described below as the front-rear direction and the left-right direction.

畦塗り機1は、図1及び図2(正面図)に示すように、走行機体90の後部に設けられた三点リンク連結機構(図示せず)に連結されて、走行機体90の前進動に応じて進行する。畦塗り機1は、走行機体90に装着されて走行機体90からの動力が入力される入力軸15aを備えた装着部10と、装着部10に設けられた旋回シリンダ11によって装着部10から左右方向に移動可能なオフセット機構20と、オフセット機構20の移動端側(後端側)に垂直方向に延びる回動支点Oを回動中心として水平方向に回動可能に配設されて入力軸15aから伝達される動力によってオフセット作業を行なう作業部30とを有してなる。   As shown in FIGS. 1 and 2 (front view), the wrinkle coater 1 is connected to a three-point link connecting mechanism (not shown) provided at the rear portion of the traveling machine body 90 so that the traveling machine body 90 moves forward. Proceed according to. The wrinkle coater 1 is mounted on the traveling machine body 90 and left and right from the mounting part 10 by a mounting part 10 having an input shaft 15a to which power from the traveling machine body 90 is input and a turning cylinder 11 provided on the mounting part 10. The offset mechanism 20 is movable in the direction, and the input shaft 15a is disposed so as to be rotatable in the horizontal direction around a rotation fulcrum O extending in the vertical direction on the moving end side (rear end side) of the offset mechanism 20. And a working unit 30 that performs an offset work with the power transmitted from.

装着部10は、左右方向に延びるヒッチフレーム12と、ヒッチフレーム12の前側に取り付けられて走行機体90の三点リンク連結機構に連結可能な連結フレーム13とを有してなる。ヒッチフレーム12の左右方向の中央下部にはギアボックス15が設けられ、このギアボックス15には前述した入力軸15aが設けられている。入力軸15aは、走行機体90のPTO軸(図示せず)からの動力を図示しない伝動軸を介して伝達されるようになっている。   The mounting portion 10 includes a hitch frame 12 that extends in the left-right direction, and a connection frame 13 that is attached to the front side of the hitch frame 12 and that can be connected to the three-point link connection mechanism of the traveling machine body 90. A gear box 15 is provided at the lower center of the hitch frame 12 in the left-right direction. The gear box 15 is provided with the input shaft 15a described above. The input shaft 15a is configured to transmit power from a PTO shaft (not shown) of the traveling machine body 90 via a transmission shaft (not shown).

オフセット機構20は、前端側をヒッチフレーム12に回動自在に連結されて後方側へ延びるオフセットフレーム21と、オフセットフレーム21の右側に沿って並設されて前端側がヒッチフレーム12の右側端部に回動自在に連結されたリンク部材22とを有してなる。リンク部材22の後端側は、オフセットフレーム21の後端部に回動自在に設けられた連結部材23に繋がる連結アーム部材24に回動自在に設けられている。オフセット機構20は、オフセットフレーム21、リンク部材22、ヒッチフレーム12及び連結アーム部材24によって平行リンク機構を形成している。   The offset mechanism 20 is rotatably connected to the hitch frame 12 on the front end side and extends rearward, and is arranged along the right side of the offset frame 21 so that the front end side is at the right end of the hitch frame 12. And a link member 22 that is rotatably connected. The rear end side of the link member 22 is rotatably provided on a connecting arm member 24 connected to a connecting member 23 that is rotatably provided on the rear end portion of the offset frame 21. In the offset mechanism 20, the offset frame 21, the link member 22, the hitch frame 12, and the connecting arm member 24 form a parallel link mechanism.

オフセットフレーム21は、前述した旋回シリンダ11の伸縮動作により左右方向に揺動可能であり、オフセットフレーム21内に設けられた図示しない動力伝達機構を介してオフセットフレーム21の後端側に設けられた略垂直方向に延びる従動軸25を回転駆動させるようになっている。従動軸25の下部には作業部30の回動支点Oとなる回転駆動軸31が従動軸25と同軸上に連結されている。   The offset frame 21 can be swung in the left-right direction by the expansion and contraction operation of the turning cylinder 11 described above, and is provided on the rear end side of the offset frame 21 via a power transmission mechanism (not shown) provided in the offset frame 21. The driven shaft 25 extending in the substantially vertical direction is driven to rotate. At the lower part of the driven shaft 25, a rotational drive shaft 31 that is a rotation fulcrum O of the working unit 30 is connected coaxially with the driven shaft 25.

回転駆動軸31の外側にはこれを覆う回転軸ケース32が配設されている。回転軸ケース32はその上端部がオフセットフレーム21の後端下部に回動可能に連結され、回転軸ケース32の下端部が作業部30に固定された状態で取り付けられている。また回転軸ケース32の上部には、回転軸ケース32に対して回動自在な前述した連結部材23が設けられている。つまり、連結部材23は回転軸ケース32及び回転駆動軸31と非結合状態にあり、回転駆動軸31を回動支点Oとして回動自在である。この連結部材23に前述した連結アーム部材24が横方向に延びて繋がっている。   A rotation shaft case 32 is disposed outside the rotation drive shaft 31 to cover it. The rotating shaft case 32 is pivotably connected to the lower end of the rear end of the offset frame 21 so that the lower end portion of the rotating shaft case 32 is fixed to the working unit 30. Further, the above-described connecting member 23 that is rotatable with respect to the rotating shaft case 32 is provided on the rotating shaft case 32. That is, the connecting member 23 is in a non-coupled state with the rotary shaft case 32 and the rotary drive shaft 31, and is rotatable about the rotary drive shaft 31 as a rotation fulcrum O. The connecting arm member 24 described above is connected to the connecting member 23 by extending in the lateral direction.

作業部30は、連結部材23と回転軸ケース32との間に繋がれた連結機構40により回動支点Oに対して回動可能であるとともに、連結機構40によりオフセット機構20の揺動に対して作業部30の作業方向を示す作業方向軸O2が走行機体90の進行方向Aと平行になるように保持される。連結機構40は、連結部材23と伸縮シリンダ41とを有してなる。伸縮シリンダ41は連結アーム部材24の先端部に枢結された固定部42と回転軸ケース32の上部との間に枢結されている。このため、伸縮シリンダ41が伸縮動すると、作業部30は、連結アーム部材24を介して回動支点Oを回動中心として回動する。なお、作業部30の回動角度範囲は伸縮シリンダ41のストロークの大きさに応じて設定される。このため、大きさストロークを有した伸縮シリンダ41を用いた場合には、作業部30を走行機体90の左右両側の一方側から他方側に向きを反転させた状態で移動させることができる。   The working unit 30 can be rotated with respect to the rotation fulcrum O by a connecting mechanism 40 connected between the connecting member 23 and the rotating shaft case 32, and the connecting mechanism 40 can swing the offset mechanism 20. The working direction axis O2 indicating the working direction of the working unit 30 is held so as to be parallel to the traveling direction A of the traveling machine body 90. The connection mechanism 40 includes a connection member 23 and a telescopic cylinder 41. The telescopic cylinder 41 is pivotally connected between the fixed portion 42 pivotally connected to the distal end portion of the connecting arm member 24 and the upper portion of the rotary shaft case 32. Therefore, when the telescopic cylinder 41 is expanded and contracted, the working unit 30 rotates about the rotation fulcrum O as the rotation center via the connecting arm member 24. The rotation angle range of the working unit 30 is set according to the stroke size of the telescopic cylinder 41. For this reason, when the telescopic cylinder 41 having a size stroke is used, the working unit 30 can be moved in a state in which the direction is reversed from one side of the left and right sides of the traveling machine body 90 to the other side.

連結機構40は、オフセット機構20の左右揺動に対して作業部30の作業方向軸O2が走行機体90の進行方向と平行になるように保持する。つまり、連結機構40は、作業部30の作業方向軸O2が前後方向に平行に延びた状態で伸縮シリンダ41の伸縮動作を規制すると、作業部30と連結部材23とを一体化させる。このため、作業部30と連結部材23とが一体化された状態で、オフセット機構20を左右方向に揺動させると、作業部30は、平行リンク機構を構成するオフセット機構20の連結アーム部材24に繋がる連結部材23を介して作業部30の作業方向軸O2が前後方向に平行に維持されたままで移動する。   The coupling mechanism 40 holds the working direction axis O2 of the working unit 30 so as to be parallel to the traveling direction of the traveling machine body 90 with respect to the left-right swing of the offset mechanism 20. That is, the connection mechanism 40 integrates the working unit 30 and the connecting member 23 when the expansion / contraction operation of the expansion / contraction cylinder 41 is restricted in a state where the working direction axis O2 of the working unit 30 extends in parallel in the front-rear direction. For this reason, when the offset mechanism 20 is swung in the left-right direction in a state where the working unit 30 and the connecting member 23 are integrated, the working unit 30 connects the connecting arm member 24 of the offset mechanism 20 constituting the parallel link mechanism. The working direction axis O2 of the working unit 30 moves while being maintained parallel to the front-rear direction via the connecting member 23 connected to the head.

作業部30は、図3(平面図)に示すように、前側から天場処理部50、前処理部60及び整畦部70を配置して構成されている。天場処理部50は水田の周辺に沿って形成された旧畦の上部(天場部)を切り崩し、前処理部60は切り崩した土の土盛りを行ない、整畦部70は盛られた土を切り崩された旧畦上に塗り付ける機能を有する。   As shown in FIG. 3 (plan view), the working unit 30 is configured by arranging a celestial processing unit 50, a preprocessing unit 60, and a trimming unit 70 from the front side. The heaven field processing unit 50 cuts the upper part (the heaven field part) of the old paddle formed along the periphery of the paddy field, the pre-processing unit 60 performs the earthing of the crushed soil, and the trimming unit 70 removes the accumulated soil. It has the function of painting on the cut-out old wall.

整畦部70は、左右方向に延びて回転動自在に支持された回転中心軸71に取り付けられた多面体ドラム73と、多面体ドラム73の右側端部に取り付けられて横方向に延びる円筒部75とを有してなる。整畦部70は整畦動力伝達ケース77を介して回転軸ケース32に連結されて支持される。整畦動力伝達ケース77内には図示しない整畦側動力伝達機構が内蔵され、この整畦側動力伝達機構は回転駆動軸31に繋がっており、回転駆動軸31からの動力が整畦側動力伝達機構を介して整畦部70に伝達されるようになっている。   The straightening section 70 is a polyhedral drum 73 attached to a rotation center shaft 71 that extends in the left-right direction and is rotatably supported, and a cylindrical section 75 attached to the right end of the polyhedral drum 73 and extending in the lateral direction. It has. The trimming unit 70 is connected to and supported by the rotary shaft case 32 via a trimming power transmission case 77. An adjustment power transmission mechanism (not shown) is built in the adjustment power transmission case 77. The adjustment power transmission mechanism is connected to the rotation drive shaft 31, and the power from the rotation drive shaft 31 is adjusted to the adjustment power. It is transmitted to the trimming unit 70 via the transmission mechanism.

前処理部60は、回転動自在な前処理ロータ61を備える。前処理ロータ61は前処理動力伝達ケース64を介して回転軸ケース32に連結されて支持される。前処理動力伝達ケース64内には、回転駆動軸31からの動力を受けて回転駆動する前処理側駆動軸66を有した前処理側動力伝達機構65が内蔵されている。前処理側駆動軸66の先端部に前処理ロータ61が挿着されている。前処理ロータ61の回転中心軸62は前処理側駆動軸66と同軸上に配設されている。前処理ロータ61は、その回転中心軸62が平面視において整畦部70の回転中心軸71と交差する方向に延びて配置されている。このため、整畦部70の回転中心軸71を旧畦Kの延びる方向に対して略直交する方向に配置すると、前処理ロータ61の回転中心軸62は旧畦Kの延びる方向に対して斜め方向に配置されることになる。   The preprocessing unit 60 includes a preprocessing rotor 61 that is rotatable. The pretreatment rotor 61 is connected to and supported by the rotary shaft case 32 via a pretreatment power transmission case 64. In the preprocessing power transmission case 64, a preprocessing side power transmission mechanism 65 having a preprocessing side drive shaft 66 that rotates by receiving power from the rotary drive shaft 31 is incorporated. A pretreatment rotor 61 is inserted into the tip of the pretreatment side drive shaft 66. The rotation center shaft 62 of the pretreatment rotor 61 is disposed coaxially with the pretreatment side drive shaft 66. The pretreatment rotor 61 is arranged so that the rotation center axis 62 thereof extends in a direction intersecting with the rotation center axis 71 of the trimming unit 70 in plan view. For this reason, when the rotation center shaft 71 of the trimming portion 70 is arranged in a direction substantially orthogonal to the direction in which the old rod K extends, the rotation center shaft 62 of the pretreatment rotor 61 is inclined with respect to the direction in which the old rod K extends. Will be placed in the direction.

天場処理部50は、回転動自在な天場処理ロータ51を備える。天場処理ロータ51は天場動力伝達ケース52を介して前処理ロータ61に支持されている。天場処理ロータ51はその回転中心軸53に複数の天場処理爪54を放射状に取り付けてなる。天場処理爪54は基端側が真っ直ぐ延び、先端側が側方に屈曲して旧畦上部を削り取る。天場処理ロータ51は、その回転中心軸53が平面視において整畦部70の回転中心軸71と交差する方向に延びるように配置されている。このため、整畦部70の回転中心軸71を旧畦Kの延びる方向に対して直交する方向に配置すると、天場処理ロータ51の回転中心軸53は旧畦Kの延びる方向に対して斜め方向に配置されることになる。つまり、天場処理ロータ51の回転中心軸53は前処理ロータ61の回転中心軸62と略平行に配置される。このため、天場処理ロータ51と前処理ロータ61の回転軌跡も略平行になり、天場処理ロータ51及び前処理ロータ61を近接配置することが可能になる。その結果、天場処理ロータ51の回転中心軸53の後端側端部を前処理ロータ61に近接した位置に配置することができる。   The celestial processing unit 50 includes a celestial processing rotor 51 that can freely rotate. The heaven treatment rotor 51 is supported by the pretreatment rotor 61 via the heaven power transmission case 52. The celestial processing rotor 51 has a plurality of celestial processing claws 54 attached radially to a rotation center shaft 53 thereof. The celestial processing claw 54 extends straight at the base end side, and the tip end side is bent laterally to scrape off the upper part of the old hook. The celestial processing rotor 51 is arranged such that its rotation center axis 53 extends in a direction intersecting with the rotation center axis 71 of the trimming unit 70 in plan view. For this reason, when the rotation center shaft 71 of the trimming portion 70 is arranged in a direction orthogonal to the direction in which the old rod K extends, the rotation center shaft 53 of the heaven field processing rotor 51 is oblique to the direction in which the old rod K extends. Will be placed in the direction. That is, the rotation center axis 53 of the heavenly processing rotor 51 is disposed substantially parallel to the rotation center axis 62 of the pretreatment rotor 61. For this reason, the rotation trajectories of the heaven processing rotor 51 and the preprocessing rotor 61 are also substantially parallel, and the heaven processing rotor 51 and the preprocessing rotor 61 can be disposed close to each other. As a result, the rear end side end portion of the rotation center shaft 53 of the celestial processing rotor 51 can be disposed at a position close to the preprocessing rotor 61.

天場動力伝達ケース52は天場処理ロータ51の基端側に配置されて天場処理ロータ51の回転中心軸53に対して直交する方向に延びる。天場動力伝達ケース52の先端部は天場処理ロータ51を覆うカバー部55に固定され、基端部は前処理ロータ61の回転中心軸62の先端部に対して上下回動自在に取り付けられている。つまり天場動力伝達ケース52は基端部を回動中心として上下方向に回動自在である。このため、天場処理ロータ51は天場動力伝達ケース52の回動支点を回動中心とし上下方向に移動可能である。その結果、天場処理爪54が大きな石等に当接して天場処理ロータ51の回転動が規制されようとすると、天場処理ロータ51は上方へ移動して天場処理ロータ51の回転動を許容する。このため、畦塗り作業の中断を未然に防止することができ、畦塗り作業を連続して行うことができる。   The celestial power transmission case 52 is disposed on the base end side of the celestial processing rotor 51 and extends in a direction orthogonal to the rotation center axis 53 of the celestial processing rotor 51. The distal end portion of the celestial power transmission case 52 is fixed to a cover portion 55 that covers the celestial processing rotor 51, and the proximal end portion is attached to the distal end portion of the rotation center shaft 62 of the pretreatment rotor 61 so as to be rotatable up and down. ing. That is, the heavenly power transmission case 52 is rotatable in the vertical direction with the base end portion as the rotation center. For this reason, the heaven processing rotor 51 is movable in the vertical direction with the rotation fulcrum of the heaven power transmission case 52 as the rotation center. As a result, when the celestial processing claw 54 comes into contact with a large stone or the like and the rotational motion of the celestial processing rotor 51 is to be restricted, the celestial processing rotor 51 moves upward to rotate the celestial processing rotor 51. Is acceptable. For this reason, interruption of the smearing operation can be prevented in advance, and the smearing operation can be performed continuously.

天場動力伝達ケース52内には天場側動力伝達機構56が内蔵されている。この天場側動力伝達機構56は、チェーン伝動式であり、前処理ロータ61の回転中心軸62からの動力を天場処理ロータ51に伝達する。さらに詳細には、天場側動力伝達機構56は、天場動力伝達ケース52の基端側に回転動自在に支持された第1スプロケット57と、天場動力伝達ケース52の先端側に回転動自在に支持された第2スプロケット58と、これらのスプロケット間に掛け渡されたチェーン59とを有してなる。   A heaven power transmission mechanism 56 is built in the heaven power transmission case 52. The heaven-side power transmission mechanism 56 is a chain transmission type, and transmits the power from the rotation center shaft 62 of the pretreatment rotor 61 to the heaven treatment rotor 51. More specifically, the heaven-side power transmission mechanism 56 includes a first sprocket 57 that is rotatably supported on the proximal end side of the heaven-power transmission case 52, and a rotational movement on the distal end side of the heaven-power transmission case 52. It has a second sprocket 58 that is freely supported and a chain 59 that spans between the sprockets.

第1スプロケット57を取り付けた回転軸57aは、その基端部が前処理ロータ61の回転中心軸62の先端部に接合した状態でボルト等の締結手段67によって前処理ロータ61に着脱可能に固定される。このため、締結手段67の締結を解いて回転軸57aを前処理ロータ61から取り外すことで、天場動力伝達ケース52及び天場処理ロータ51を含んだ組み立て部品を前処理ロータ61から脱着することができる。このため、天場処理作業が必要な場合に天場処理ロータ51を前処理ロータ61に装着したり、天場処理作業が不要なときに天場処理ロータ51を前処理ロータ61から脱着したりすることができる。つまり、畦塗り作業の内容に応じて天場処理ロータ51を装着し及び脱着することができる。   The rotary shaft 57a to which the first sprocket 57 is attached is detachably fixed to the pretreatment rotor 61 by fastening means 67 such as bolts with its base end joined to the tip of the rotation center shaft 62 of the pretreatment rotor 61. Is done. For this reason, the assembly part including the heavenly power transmission case 52 and the heavenly processing rotor 51 is detached from the preprocessing rotor 61 by unfastening the fastening means 67 and removing the rotating shaft 57a from the preprocessing rotor 61. Can do. For this reason, when the heaven processing operation is necessary, the heaven processing rotor 51 is attached to the preprocessing rotor 61, or when the heaven processing operation is unnecessary, the heaven processing rotor 51 is detached from the preprocessing rotor 61. can do. That is, the heaven field processing rotor 51 can be attached and detached according to the contents of the haze application.

ここで、天場処理ロータ51は前処理ロータ61に近接した位置に配置されているため、作業部30全体の前後方向長さを短くすることができ、作業部30の小型化を図ることができる。また、天場処理ロータ51及び前処理ロータ61の各回転中心軸53、62間の距離は短いので、天場動力伝達ケース52及び天場側動力伝達機構56の長さを短くすることがでる。その結果として作業部30の重量を軽くすることができる。なお、天場側動力伝達機構56はギヤ伝動式にしてもよい。   Here, since the celestial processing rotor 51 is disposed at a position close to the preprocessing rotor 61, the length of the entire working unit 30 in the front-rear direction can be shortened, and the working unit 30 can be downsized. it can. Further, since the distance between the rotation center shafts 53 and 62 of the heaven processing rotor 51 and the preprocessing rotor 61 is short, the length of the heaven power transmission case 52 and the heaven power transmission mechanism 56 can be shortened. . As a result, the weight of the working unit 30 can be reduced. The heaven-side power transmission mechanism 56 may be a gear transmission type.

天場処理ロータ51は、図1及び図2に示すように、前処理ロータ61を覆うカバー部63と天場処理ロータ51を覆うカバー部55との間に回動自在に取り付けられた押圧部80によって下方に付勢されている。押圧部80はカバー55、63部間に回動自在に取り付けられた支持部材81と支持部材81の下端部に取り付けられたばね部材82とを有してなる。ばね部材82は圧縮された状態で支持部材81に取り付けられて天場処理ロータ51を下方に付勢する。このため、天場処理ロータ51の天場処理爪54が石等に当接して天場処理ロータ51が上方へ移動したときの衝撃をばね部材82によって吸収することができる。   As shown in FIGS. 1 and 2, the celestial processing rotor 51 includes a pressing portion that is rotatably attached between a cover portion 63 that covers the preprocessing rotor 61 and a cover portion 55 that covers the celestial processing rotor 51. 80 is biased downward. The pressing portion 80 includes a support member 81 rotatably attached between the covers 55 and 63 and a spring member 82 attached to the lower end portion of the support member 81. The spring member 82 is attached to the support member 81 in a compressed state, and biases the celestial processing rotor 51 downward. Therefore, the spring member 82 can absorb the impact when the heaven treatment claw 54 of the heaven treatment rotor 51 abuts against a stone or the like and the heaven treatment rotor 51 moves upward.

次に、畦塗り機1の動作について水田Sの一辺Saを畦塗りする場合を例にして説明する。図1に示すように、先ず、走行機体90を水田Sの一辺Saに沿うように配置する。そして、作業部30の作業方向軸O2が走行機体90の進行方向と平行になるように、伸縮シリンダ41を伸縮動させ、そして伸縮シリンダ41の伸縮動作を規制する。その結果、作業部30は図2に示す連結部材23及び回転軸ケース32と一体化されて、平行リンク機構をなすオフセット機構20の右側揺動によって作業部30の作業方向が前後方向に平行に保持されながら、作業部30を走行機体前進走行により畦塗り作業が可能な右側オフセット作業位置に移動させることができる。   Next, the operation of the hull coater 1 will be described using a case where one side Sa of the paddy field S is hulled as an example. As shown in FIG. 1, first, the traveling machine body 90 is arranged along one side Sa of the paddy field S. Then, the telescopic cylinder 41 is expanded and contracted so that the working direction axis O2 of the working unit 30 is parallel to the traveling direction of the traveling machine body 90, and the expansion and contraction operation of the telescopic cylinder 41 is restricted. As a result, the working unit 30 is integrated with the connecting member 23 and the rotary shaft case 32 shown in FIG. 2, and the working direction of the working unit 30 is made parallel to the front-rear direction by the right-side swing of the offset mechanism 20 that forms a parallel link mechanism. While being held, the working unit 30 can be moved to the right offset work position where the paintwork can be applied by forward traveling of the traveling machine body.

そして、走行機体90を前進動させるとともに作業部30を駆動させる。作業部30が前側に進行しながら駆動すると、天場処理部50が水田Sの一辺Saの旧畦上部(天場部)を切り崩し、前処理部60が切り崩した土の土盛りを行ない、整畦部70が盛られた土を切り崩された旧畦K上に塗り付けて、水田Sの一辺Saが連続的に畦塗りされる。   Then, the traveling machine body 90 is moved forward and the working unit 30 is driven. When the working unit 30 is driven forward while driving, the heaven field processing unit 50 cuts the upper part of the old paddle (the heaven field part) of the side Sa of the paddy field S, and the preprocessing unit 60 fills the soil that has been cut and trimmed. The soil on which the portion 70 is piled is applied on the old paddle K that has been cut, and one side Sa of the paddy field S is continuously padded.

ここで、天場処理ロータ51の天場処理爪54の前側部分(裏側部分)には、走行機体90の前進動に伴って旧畦の上部の土を介して後方側へ向く力Fが作用するが、天場処理爪54は斜め方向に傾いているので、その力Fの平行成分Fxは天場処理爪54の延びる方向に沿って作用して、天場処理爪54に直交する方向の直交成分力Fyを小さくする。つまり、天場処理爪54に直交する力を小さくすることができる。このため、天場処理爪54に作用する力Fyによって天場処理ロータ51に発生する振動を抑制することができる。なお、力Fyの大きさは、天場処理ロータ51の回転中心軸53の延びる方向と旧畦Kの延びる方向とのなす角度θが大きく成る程小さくなる。なお、実施例では、角度θを25°程度に設定しているが、天場処理ロータ51、前処理ロータ61、多面体ドラム73等の回転径や大きさによって、最適な角度を設定すればよい。   Here, a force F directed to the rear side through the soil above the old fence is applied to the front side portion (back side portion) of the heaven processing claw 54 of the heaven processing rotor 51 as the traveling body 90 moves forward. However, since the celestial processing claw 54 is inclined in an oblique direction, the parallel component Fx of the force F acts along the direction in which the celestial processing claw 54 extends, and in a direction orthogonal to the celestial processing claw 54. The orthogonal component force Fy is reduced. That is, the force orthogonal to the celestial processing claw 54 can be reduced. For this reason, the vibration which generate | occur | produces in the celestial process rotor 51 by the force Fy which acts on the celestial process claw 54 can be suppressed. The magnitude of the force Fy decreases as the angle θ formed between the direction in which the rotation center shaft 53 of the celestial processing rotor 51 extends and the direction in which the old hammer K extends increases. In the embodiment, the angle θ is set to about 25 °, but an optimal angle may be set according to the rotation diameter and size of the celestial processing rotor 51, the preprocessing rotor 61, the polyhedral drum 73, and the like. .

また天場処理ロータ51はその回転中心軸53が旧畦Kの延びる方向に対して斜め方向に向いて配置されているので、図4(断面図)に示すように、天場処理ロータ51によって削られた旧畦Kの上部の土の一部は水田S側に向かって飛ばされて、旧畦Kの際の水田S内に落下する。このため、天場処理ロータ51によって削られた土の全てがそのまま旧畦Kの上部に堆積して残ることはなく、前処理ロータ61によって削られた土の一部が旧畦上部に供給されても、旧畦Kの上部に供給される土の量を旧畦上部が削られる前の旧畦上部を形成する土の量よりも多くなることはない。このため、整畦部70によって整畦された新畦Ksの高さを旧畦Kのそれと略同じにしたり低くめにしたりするような、新畦Ksの高さ調整をし易くすることができる。   Further, since the rotation center axis 53 of the celestial processing rotor 51 is arranged in an oblique direction with respect to the direction in which the old hammer K extends, as shown in FIG. Part of the soil above the shaved old paddle K is blown toward the paddy field S and falls into the paddy field S at the time of the old paddle K. For this reason, not all of the soil shaved by the heavenly-processed rotor 51 is deposited and remains on the upper part of the old dredge K, and a part of the soil shaved by the pretreatment rotor 61 is supplied to the upper part of the old dredger. However, the amount of soil supplied to the upper part of the old dredging K does not become larger than the amount of soil forming the old dredging upper part before the old dredging upper part is shaved. For this reason, it is possible to easily adjust the height of the new basket Ks so that the height of the new basket Ks trimmed by the trimming unit 70 is substantially the same as or lower than that of the old basket K. .
