Description

本発明は畦を整形する整畦体を有する畦塗り機において、整畦体の内、畦の上面を整形する上面整畦部に、畦上面の表層土を適度に圧密させる機能を持たせた畦塗り機の整畦体に関するものである。   The present invention has a function in which the surface soil of the upper surface of the cocoon is appropriately compacted in the upper surface trimming part that shapes the upper surface of the cocoon in the glazing machine in the glazing machine having the rectifier that shapes the cocoon. The present invention relates to the trimming body of a coater.

畦塗り機の整畦体は円錐台形状の法面整畦部とその軸方向先端に連結される円筒形状の上面整畦部を持ち、畦塗り機の走行時に軸回りに回転することにより前処理体が先行して緩めた旧畦の土を新たに法面と上面を有する畦として整形する。整畦体は畦塗り機の走行速度より速い速度で転動し得る回転速度が与えられ、スリップ回転することで、畦の法面と上面を転圧し、表層土を圧密させる機能を発揮する(特許文献1参照)。   The brush coater has a frusto-conical sloped surface adjuster and a cylindrical upper surface adjuster connected to its tip in the axial direction. The old dredged soil that has been loosened by the treatment body is reshaped as a dredging having a slope and an upper surface. The trimming body is given a rotational speed that allows it to roll at a speed faster than the traveling speed of the paddy coater, and exerts the function of compacting the surface soil by rolling on the slope and top surface of the paddle by slip rotation ( Patent Document 1).

整畦体がスリップ回転することで、法面整畦部と上面整畦部が畦の法面と上面の双方に圧力を加えるため、引き締まった畦を整形することができる。土は上面から作用する圧力によって法面側へ滑ろうとし、そのときの反力を法面整畦部が受けることができるため、上面整畦部によって上面から圧力を与えるだけでも畦に対する一定の締め固め効果を得ることはできる(特許文献2参照)。   As the trimming body rotates by slip, the slope trimming section and the top trimming section apply pressure to both the slope and the top of the collar, so that the tightened collar can be shaped. The soil tries to slide to the slope side by the pressure acting from the upper surface, and the reaction force at that time can be received by the slope trimming unit. A compaction effect can be obtained (see Patent Document 2).

但し、特許文献1、2では、整畦体が回転するときの落差や段差を利用して畦上面を叩くことにより土に動的な圧力を与えるため、表層土を乱す、あるいは飛散させる可能性がある。   However, in Patent Documents 1 and 2, dynamic pressure is applied to the soil by striking the top surface of the saddle using a drop or a step when the trimming body rotates, so that the surface soil may be disturbed or scattered. There is.

これに対し、上面整畦部の外周に接続される、特許文献1のような複数枚の羽根板を屈曲させ、1枚の羽根板が2段階に畦上面に接触する形状にすることで、円筒面を有する羽根板を畦上面に接触させる場合より羽根板による土への加圧効果を向上させる方法がある(特許文献3参照)。   On the other hand, by bending a plurality of blades as in Patent Document 1 connected to the outer periphery of the upper surface trimming part and making one blade in contact with the upper surface in two stages, There is a method for improving the pressurizing effect on the soil by the blade plate compared to the case where a blade plate having a cylindrical surface is brought into contact with the upper surface of the ridge (see Patent Document 3).

特開2000−37106号公報(請求項1、段落0013、0019、図3、図4、図7〜図9)JP-A-2000-37106 (Claim 1, paragraphs 0013 and 0019, FIGS. 3, 4, and 7 to 9) 特開2006−55121号公報(請求項1、段落0021〜0022、図2、図3)Japanese Patent Laying-Open No. 2006-55121 (Claim 1, paragraphs 0021 to 0022, FIGS. 2 and 3) 特許第3997473号公報(請求項1、段落0008、0012〜0014、図3、図6)Japanese Patent No. 3997473 (Claim 1, paragraphs 0008, 0012 to 0014, FIGS. 3 and 6)

特許文献3のように屈曲した羽根板を畦上面に接触させる方法によれば、上面整畦部の軸方向を向いた凸条部を挟んで羽根板表面の向きが相違することで、凸条部がない連続した平面、もしくは曲面を有する羽根板を用いる場合より、軸回りの回転時に畦上面に接触する面積が小さくなる。この結果、畦上面に接触するときに土に与える圧力が大きくなり、加圧効果が高まる利点を有するとされている(段落0012)。   According to the method in which the bent blade plate is brought into contact with the upper surface of the ridge as in Patent Document 3, the direction of the blade plate surface is different with the convex portion facing the axial direction of the upper surface adjusting portion being sandwiched. The area of contact with the upper surface of the heel during rotation around the axis is smaller than when using a continuous flat surface having no part or a blade having a curved surface. As a result, it is said that there is an advantage that the pressure applied to the soil increases when it comes into contact with the upper surface of the ridge and the pressurizing effect is enhanced (paragraph 0012).

特許文献3では羽根板が屈曲することで、屈曲しない場合より羽根板から畦上面に与える圧力が大きくなり、その分、羽根板が受ける反力も大きくなるため、羽根板から畦上面に十分な圧力を与える目的を果たすには上面整畦部自体が反力に抵抗できるだけの剛性を有している必要がある。   In Patent Document 3, since the slats are bent, the pressure applied from the slats to the upper surface of the coffin is greater than when the slats are not bent, and the reaction force received by the slats is correspondingly increased. In order to achieve the purpose of providing the upper surface, it is necessary that the upper surface adjusting portion itself has a rigidity sufficient to resist the reaction force.

しかしながら、上面整畦部の本体は対向する円形状のリングと、両リングを軸方向につなぐプレート状のつなぎ材から、半径方向の剛性、あるいはねじり剛性が乏しい骨組みとして構成されているため、上面整畦部の本体自体が畦上面を押圧するときに半径方向等に変形し易く、所期の目的を達成するだけの圧力を与えられない可能性がある。   However, since the main body of the upper surface trimming part is configured as a framework having poor radial rigidity or torsional rigidity from the opposing circular rings and the plate-shaped connecting material that connects both rings in the axial direction, There is a possibility that the main body of the trimming section itself is easily deformed in the radial direction or the like when pressing the upper surface of the collar, and the pressure sufficient to achieve the intended purpose may not be applied.

また羽根板は周方向の一端部において本体のつなぎ材にボルト等により接合されるが(段落0008)、上記の通り、上面整畦部の本体が半径方向の力に対して抵抗できるだけの剛性を持たないことから、つなぎ材が半径方向に変形(振動)し易いため、羽根板の接合状態での安定性に欠け、羽根板が畦上面を押圧するときに損傷する可能性がある。加えて羽根板はボルトを覆う状態にないため(図6)、ボルトによる羽根板の接合部分に土が入り込み、ボルトと羽根板の接合部分の損傷を早める可能性もある。   In addition, the blade is joined to the connecting material of the main body by a bolt or the like at one end portion in the circumferential direction (paragraph 0008). As described above, the main body of the upper surface trimming part has rigidity sufficient to resist the radial force. Since it does not have, the connecting material is likely to be deformed (vibrated) in the radial direction, so that the stability in the joined state of the slats is lacking, and there is a possibility that the slats may be damaged when pressing the top surface of the saddle. In addition, since the slats are not in a state of covering the bolts (FIG. 6), there is a possibility that soil enters the joint part of the slats by the bolts and accelerates damage to the joint part of the bolts and slats.

なお、特許文献3で上面整畦部の本体を骨組み(フレーム)構造にしていることは、本体のプレート状のつなぎ材に羽根板をボルトを用いて接合するために必要な要件とされている(段落0008)。すなわちリングとつなぎ材から本体を構成することは、羽根板とつなぎ材を貫通するボルトにつなぎ材の背面(裏面)からナット等を締結するためであるから、ボルトの挿入とナット締め付け作業を行う上で、本体を開放した形状にしておくことは不可欠になっている。   In Patent Document 3, the fact that the main body of the upper surface trimming part has a framework (frame) structure is a requirement necessary for joining the blade plate to the plate-like connecting material of the main body using bolts. (Paragraph 0008). That is, the main body is composed of the ring and the connecting material because the nut and the like are fastened from the back surface (back surface) of the connecting material to the bolt that penetrates the blade and the connecting material. Above, it is essential to keep the body open.

本発明は上記背景より、整畦体のスリップ回転により畦上面の表層土を押圧する上で、確実に圧力を与えながら、損傷に対する耐久性の高い形態の畦塗り機の整畦体を提案するものである。   Based on the above background, the present invention proposes a trimming body of a glider having a high durability against damage while reliably applying pressure when pressing the surface soil on the top surface of the shear plane by slip rotation of the trimming body. Is.

請求項1に記載の発明の整畦体は、軸回りの回転により畦の法面を整形する法面整畦部と、その軸方向先端部に連結されて法面整畦部と共に回転し、畦の上面を整形する上面整畦部とを有する、畦塗り機の整畦体において、
上面整畦部が多角柱状の筒状部材と、この筒状部材の側面に重なり、筒状部材の周方向に間隔を置いて接続される複数枚の弾性を有する羽根板を備え、前記複数枚の羽根板が全体として前記筒状部材の表面を覆う状態にあることを構成要件とする。筒状部材の側面は筒状部材の周方向の面を指す。
The trimming body of the invention according to claim 1 is rotated with the slope trimming portion connected to the tip end portion in the axial direction, and a slope trimming portion that shapes the slope of the collar by rotation around the axis, In a trimming body of a glaze coater having an upper surface trimming part for shaping the upper surface of the collar,
The plurality of sheets are provided with a cylindrical member having an upper surface trimming section and a plurality of elastic blade plates that overlap the side surfaces of the cylindrical member and are connected at intervals in the circumferential direction of the cylindrical member. The slats are in a state of covering the surface of the tubular member as a whole. The side surface of the cylindrical member refers to the circumferential surface of the cylindrical member.

複数枚の羽根板が全体として筒状部材を覆うとは、上面整畦部が回転するときに、常にいずれかの羽根板が畦上面に接触する状態になるように複数枚の羽根板が筒状部材を覆うことを言い、筒状部材の側面部分が畦上面に対向するときと稜線部分が畦上面に対向するときのいずれも、筒状部材と畦上面との間に羽根板が介在する状態になることを言う。   The fact that the plurality of blades cover the tubular member as a whole means that when the upper surface adjusting portion rotates, the plurality of blades are in a state where any one of the blades is in contact with the upper surface. A blade is interposed between the tubular member and the heel surface both when the side surface portion of the cylindrical member faces the heel surface and when the ridge line portion faces the heel surface. Say to be in a state.

具体的には羽根板が筒状部材のいずれかの側面に重なって接続される接続部と、この接続部に連続し、上面整畦部の回転方向下流側に隣接する側面側へ張り出す張出部からなり、この張出部が上面整畦部の回転方向下流側に位置する羽根板の接続部を覆う状態にあることにより(請求項2)、複数枚の羽根板が全体として筒状部材を覆う形になる。回転方向下流側とは、上面整畦部が軸回りに回転するときに回転の向きの後方側を指し、回転方向下流側の羽根板は畦上面には、相対的に上流側である回転の向きの前方側に位置する羽根板の後に接触する。   Specifically, a connecting portion in which the blade plate is connected to overlap one of the side surfaces of the cylindrical member, and a tension that extends to the side surface adjacent to the connecting portion and adjacent to the downstream side in the rotation direction of the upper surface trimming portion. Since the overhanging portion is in a state of covering the connecting portion of the blade plate located on the downstream side in the rotation direction of the upper surface adjusting portion (Claim 2), the plurality of blade plates are generally cylindrical. It becomes a shape that covers the member. The downstream side in the rotational direction refers to the rear side in the direction of rotation when the upper surface trimming part rotates about the axis, and the blades on the downstream side in the rotational direction are relatively upstream of the rotational surface on the upper surface. It comes in contact after the blade located on the front side of the orientation.

いずれかの羽根板が畦上面に接触する状態となるように、羽根板が筒状部材の表面を覆うことで、筒状部材の稜線部分が畦上面を押圧するときと、側面部分が畦上面を押圧するときのいずれのときにも直接的には羽根板を介して畦上面を押圧することになる。   When the blade plate covers the surface of the cylindrical member so that any of the blade plates are in contact with the upper surface of the cylindrical member, the ridge line portion of the cylindrical member presses the upper surface of the cylindrical member, and the side surface portion is the upper surface of the vertical surface. At any time when pressing the, the upper surface of the heel is pressed directly through the blade.

複数枚の羽根板が全体として筒状部材を覆う状態は、上面整畦部が回転し、少なくとも1枚の羽根板が畦上面に接触しているときに得られればよいが、例えば羽根板が筒状部材の外周側へ凸となる曲面を形成していれば、上面整畦部の回転中に羽根板が筒状部材を覆う状態を得易い。羽根板が接続部と張出部からなる場合には、張出部が筒状部材の外周側へ凸となる曲面を形成していればよい。   The state in which the plurality of blades cover the tubular member as a whole may be obtained when the upper surface adjusting portion rotates and at least one blade is in contact with the upper surface. If the curved surface which is convex toward the outer peripheral side of the cylindrical member is formed, it is easy to obtain a state in which the blade plate covers the cylindrical member during rotation of the upper surface trimming portion. In the case where the blade is composed of a connecting portion and an overhanging portion, the overhanging portion only needs to form a curved surface that protrudes toward the outer peripheral side of the tubular member.

羽根板の張出部が接続部と同一の平面をなして張り出す場合には、上面整畦部の回転中に羽根板の全面がほぼ同時に畦上面に接触し易く、羽根板の一部が土と接触している時間が長くなるため、平面が畦上面の土を引き摺る可能性がある。これに対し、張出部が筒状部材の外周側へ凸の曲面をなすことで、各羽根板が円筒面の一部に近い形状を形成し、羽根板の一部が土と接触している時間が短くなるため、羽根板は土を引き摺ることなく、スリップ回転により同一箇所を曲面によって連続的に均すことができることになる。   When the slats of the slats extend over the same plane as the connecting part, the entire surface of the slats easily touches the top surface of the slats almost simultaneously during the rotation of the top surface trimming part. Since the time in contact with the soil becomes longer, the flat surface may drag the soil on the upper surface of the fence. On the other hand, the projecting portion forms a curved surface that protrudes toward the outer periphery of the cylindrical member, so that each blade has a shape close to a part of the cylindrical surface, and a part of the blade is in contact with the soil. Therefore, the blades can be leveled continuously by a curved surface by slip rotation without dragging the soil.

上面整畦部が多角柱状の筒状部材と筒状部材の側面に重なって接続される弾性を有する羽根板からなることで、畦上面に直接、接触する羽根板は筒状部材の形状に倣って変形しながら畦上面を押圧する。一方、筒状部材は断面上の中心位置を一定にしたまま回転するから、中心から多角柱の稜線までの距離と側面までの距離が相違するため、稜線部分が押圧するときと、側面部分が押圧するときとでは圧力に差が生じ、稜線部分から押圧するときに圧力が大きくなる。   Since the upper surface trimming part is composed of a polygonal cylindrical member and an elastic blade that is connected to the side surface of the cylindrical member, the blade that directly contacts the upper surface follows the shape of the cylindrical member. The upper surface of the heel is pressed while deforming. On the other hand, since the cylindrical member rotates while keeping the center position on the cross section constant, the distance from the center to the ridgeline of the polygonal column and the distance to the side surface are different. There is a difference in pressure from when pressing, and the pressure increases when pressing from the ridgeline portion.

従って上面整畦部は筒状部材の稜線部分の外周側に位置する羽根板から畦上面を押圧するときと、側面部分の外周側に位置する羽根板から畦上面を押圧するときとで異なる圧力で畦上面を押圧するため、スリップ回転することにより同一地点を羽根板から2通りの圧力で加圧することが可能である。   Therefore, the upper surface trimming portion has different pressures when pressing the upper surface from the blade located on the outer peripheral side of the ridge line portion of the cylindrical member and when pressing the upper surface from the blade located on the outer peripheral side of the side surface portion. In order to press the upper surface of the saddle, it is possible to pressurize the same point from the slats with two different pressures by slip rotation.

同一地点を2通りの圧力で加圧できることで、畦上面を締め固める効果と畦を長さ方向に均等に仕上げる効果が得られ、土質、あるいは土の含水量の差異に関係なく、畦上面の表層土を適度に圧密させながら、均質に仕上げることが可能になる。含水量が多ければ、圧密により余剰水は自然に土から排除される。   The ability to pressurize the same point with two different pressures has the effect of compacting the top surface of the reed and the effect of finishing the reed evenly in the length direction, regardless of soil quality or soil moisture content. It is possible to finish the surface soil uniformly while properly compacting the surface soil. If the water content is high, excess water is naturally removed from the soil by consolidation.

ここで、筒状部材の稜線部分(角部分)が直接、畦上面に接触する場合には、稜線部分から畦上面に与える圧力が側面部分からの圧力より大きいため、羽根板が均した土を稜線部分の両側に押し出すように作用し、畦上面に稜線部分の痕跡として溝が形成されることが想定される。このことは多角形状の表面を形成する特許文献3の凸条部にも言える。   Here, when the ridge line part (corner part) of the cylindrical member is in direct contact with the saddle upper surface, the pressure applied from the ridge line part to the saddle upper surface is greater than the pressure from the side face part. It is assumed that a groove is formed as a trace of the ridge line portion on the upper surface of the ridge by acting so as to be pushed out on both sides of the ridge line portion. This can also be said for the protruding portion of Patent Document 3 that forms a polygonal surface.

これに対し、本発明では複数枚の羽根板が全体として筒状部材の表面を覆うことで、筒状部材の稜線部分から畦上面を押圧するときに羽根板が圧力を分散させる作用を果たすため、稜線部分から畦上面を押圧し、締め固めながらその圧力を分散させ、土を均等に均すことが可能になっている。   On the other hand, in the present invention, the plurality of blades cover the surface of the tubular member as a whole, so that the blades act to disperse the pressure when pressing the upper surface from the ridge line portion of the tubular member. It is possible to press the upper surface of the ridge from the ridgeline portion and disperse the pressure while compacting to evenly level the soil.

また上面整畦部の本体である筒状部材は多角柱状で、骨組み形式ではない多面体であることで、筒状部材自体が半径方向及び周方向に高い剛性を有し、ねじり剛性も高く、半径方向と周方向への圧力に対して変形しにくい性質を有するため、筒状部材自体が反力に対して高い安定性を保有する。このため、畦上面の押圧時に羽根板から十分な反力を与えることができる上、筒状部材自体が変形しにくいことで、羽根板からの加圧効果が確実に発揮され、想定通りの圧力を与えることが可能である。   In addition, the cylindrical member that is the main body of the upper surface trimming unit is a polygonal column, and is a polyhedron that is not a skeleton type, so that the cylindrical member itself has high rigidity in the radial direction and circumferential direction, high torsional rigidity, The cylindrical member itself has high stability against the reaction force because it has the property of being difficult to be deformed with respect to the pressure in the direction and the circumferential direction. For this reason, a sufficient reaction force can be applied from the blades when pressing the upper surface of the flange, and since the cylindrical member itself is not easily deformed, the pressure effect from the blades is reliably exhibited, and the pressure as expected It is possible to give

筒状部材に必要とされる曲げ剛性とねじり剛性はそれを構成する板(プレート)の板厚を一定以上に設定することで確保されるが、筒状部材の端面を閉塞する板や内接する板を付加することで剛性は格段に向上する。   The bending rigidity and torsional rigidity required for the cylindrical member are ensured by setting the plate thickness of the plate (plate) constituting the cylindrical member to a certain level or more. The rigidity is remarkably improved by adding a plate.

更に筒状部材が多面体であることで、ボルト等を用いて羽根板を筒状部材に接合する上で、筒状部材との十分な接触面積を確保することができるため、羽根板自体の変形に対する安定性が向上し、損傷に対する耐久性が高まる。   Furthermore, since the cylindrical member is a polyhedron, a sufficient contact area with the cylindrical member can be secured when the blade plate is joined to the cylindrical member using a bolt or the like. This improves the stability against damage and increases the durability against damage.

特に羽根板の張出部がその周方向に、その羽根板が接続されている筒状部材の側面から前記下流側の側面を超える長さを有している場合には(請求項3)、筒状部材の稜線部分に2枚の羽根板が重なるため、羽根板が畦上面を均す上で、筒状部材の稜線部分に1枚の羽根板が位置する場合より羽根板による畦上面への圧力を分散させることが可能であり、畦上面を平滑に仕上げる効果が向上する。   In particular, when the overhanging portion of the slat has a length in the circumferential direction exceeding the downstream side surface from the side surface of the tubular member to which the slat plate is connected (Claim 3), Since the two slats overlap the ridgeline part of the cylindrical member, when the slats level the top surface of the sword, the top surface of the slats by the slats is higher than when one slat is located at the ridgeline part of the cylindrical member. It is possible to disperse the pressure, and the effect of finishing the top surface of the heel smoothly is improved.

例えば稜線部分が直接、畦上面に接触する場合には、稜線部分からの圧力が集中的に畦上面に作用するが、筒状部材の稜線部分に2枚の羽根板が重なることで、稜線部分から畦上面に与える圧力の分散効果が増すことになる。また羽根板は弾性を有する(曲げ変形可能な)板であるから、2枚の羽根板が重なる場合には、畦上面に直接、接触する上面整畦部の表面の曲率が羽根板が1枚の場合より小さくなり、曲面が緩やかになるため、畦上面の均し効果も向上し、より平滑に仕上げることが可能である。   For example, when the ridge portion directly contacts the ridge surface, the pressure from the ridge portion acts on the ridge surface in a concentrated manner, but the two blades overlap the ridge line portion of the cylindrical member. Therefore, the dispersion effect of the pressure applied to the upper surface of the heel increases. In addition, since the slats are elastic (bendable and deformable), when two slats overlap, the curvature of the surface of the top surface adjustment portion that directly contacts the top surface of the slats is one. Since the surface becomes smaller and the curved surface becomes gentler, the leveling effect on the upper surface of the ridge is improved, and a smoother finish is possible.

また複数枚の羽根板が全体として筒状部材の表面を覆う状態にあることで(請求項1)、あるいは羽根板の張出部が上面整畦部の回転方向下流側に位置する羽根板の表面を覆う状態にあることで(請求項2)、上流側に位置する羽根板の下流側の部分が下流側に位置する羽根板の接合部を覆う(被覆する)状態が得られるため、羽根板の接合部分に土が入り込み、接合部分の損傷を早める可能性が低下し、損傷が抑制される。   Further, the plurality of blades are in a state of covering the surface of the tubular member as a whole (Claim 1), or the blade plate overhanging the blade plate is located on the downstream side in the rotation direction of the upper surface adjusting portion. By being in a state of covering the surface (Claim 2), the downstream side portion of the blade plate positioned on the upstream side can cover (cover) the joint portion of the blade plate positioned on the downstream side. Soil enters the joining portion of the plate, reducing the possibility of accelerating the damage of the joining portion, and suppressing the damage.

上面整畦部の回転に伴い、羽根板が畦上面から離脱しようとするときには、羽根板が弾性を有することで、復元力によって畦上面の土を跳ね上げることが想定されるが、この問題は羽根板の張出部の周方向先端部を筒状部材側へ湾曲、もしくは屈曲させることで(請求項4)、抑制することが可能である。張出部の周方向先端部は上面整畦部の回転方向下流側の端部であり、張出部は筒状部材の外周側へ凸の曲面を形成し得ることから、筒状部材側へ湾曲、もしくは屈曲するとは、先端部をそれ以外の張出部の部分より大きい曲率で湾曲させる、もしくは屈曲させることを言う。   With the rotation of the upper surface trimming part, when the slats are going to be detached from the top surface of the cocoon, it is assumed that the slats have elasticity, so that the soil on the top surface of the cocoon is raised by the restoring force. It can be suppressed by curving or bending the circumferential tip of the overhanging portion of the blade plate toward the cylindrical member (claim 4). The circumferential tip of the overhanging portion is the end of the upper surface trimming portion on the downstream side in the rotation direction, and the overhanging portion can form a convex curved surface on the outer circumferential side of the tubular member. The term “curved or bent” means that the distal end portion is bent or bent with a larger curvature than the other protruding portion.

例えば羽根板の張出部の先端部がそれ以外の部分と同一の曲率である(羽根の張出部が先端部まで一様の曲面、もしくは平面である)場合、先端部が畦上面から離脱するときに、弾性変形状態から急激に復元するときの反力により畦上面の土を畦側へ弾くことが考えられる。これに対し、張出部の周方向先端部が筒状部材側へ湾曲等することで、図2に鎖線で示すように先端部が離脱するまで畦上面に接触した状態を維持することができる上、離脱時には上面整畦部の回転に伴って先端部が畦上面上を滑りながら離脱するため、土を弾くことなく、均すことが可能である。   For example, if the tip of the overhanging portion of the slat has the same curvature as the other parts (the overhanging portion of the blade is a uniform curved surface or a flat surface up to the tip), the tip is detached from the top surface In this case, it is conceivable that the soil on the top surface of the reed is repelled toward the reed side by the reaction force when rapidly restoring from the elastic deformation state. On the other hand, the circumferential tip portion of the overhanging portion is curved toward the cylindrical member, so that the state where the tip portion is in contact with the tip surface can be maintained until the tip portion is detached as shown by a chain line in FIG. When the top surface is disengaged, the tip end portion is disengaged while sliding on the top surface of the corrugated surface as the upper surface trimming portion rotates.

請求項2では羽根板が筒状部材の側面に重なる接続部と側面から回転方向下流側へ張り出す張出部を有することで、張出部が上面整畦部の回転時に筒状部材の周面(側面と稜線)に重なる状態と周面から離れる状態を繰り返すため、張出部は法面整畦部との境界(連結)部分において畦上面上の土と畦法面の土を不連続にする可能性がある。   According to a second aspect of the present invention, the blade has a connecting portion that overlaps the side surface of the tubular member and a projecting portion that projects from the side surface to the downstream side in the rotation direction. In order to repeat the state of overlapping with the surface (side surface and ridgeline) and the state of separating from the peripheral surface, the overhanging part discontinues the soil on the top surface of the ridge and the soil on the slope surface at the boundary (connection) with the slope trimming part There is a possibility.

畦上面と畦法面の境界部分における土が不連続になる可能性は、羽根板の法面整畦部側の端部に、上面整畦部の回転方向上流側から下流側へかけて上面整畦部側から法面整畦部側へ接近する形状をした移行部が形成されることで(請求項5)、回避することが可能である。移行部は羽根板の、主に張出部の法面整畦部側に形成される。   The possibility of soil discontinuity at the boundary between the upper surface and the slope surface is that the upper surface extends from the upstream side to the downstream side in the rotational direction of the upper surface leveling unit at the end of the blade plate on the slope leveling side. This can be avoided by forming a transition portion having a shape approaching from the trimming portion side to the slope trimming portion side (Claim 5). The transition part is formed mainly on the slope trimming part side of the overhang part of the slats.

移行部は回転方向上流側から下流側へかけて上面整畦部の軸方向の長さが大きくなる形状をし、例えば三角形状や台形状等に形成され、少なくとも一部は法面整畦部の羽根板に畦側から重なる。移行部はそれがない場合の、例えば長方形状の羽根板に付加的に接続されるか、一体となった形で連続する。   The transition portion has a shape in which the axial length of the upper surface adjusting portion increases from the upstream side to the downstream side in the rotational direction, and is formed in, for example, a triangular shape or a trapezoidal shape, and at least a part of the slope adjusting portion It overlaps with the slats from the heel side. The transition part is additionally connected to, for example, a rectangular slat in the absence of it, or continues in an integrated form.

移行部は上面整畦部の一部であることで、上面整畦部の回転に伴って畦上面に接近し、接触するときに筒状部材の周面に重なろうとするため、羽根板の法面整畦部側の端部に形成され、法面整畦部の羽根板に重なることと併せて、畦上面上の土を法面整畦部側へ流す働きをする。加えて法面整畦部の羽根板と共に、あるいは法面整畦部の羽根板の一部として畦上面と法面の境界部分における土を均し、畦の内部側へ圧密させる働きをする。結果的に畦上面と畦法面の境界部分における土が連続的に、均等に均されるため、不連続になる事態が回避される。   Since the transition part is a part of the upper surface adjusting part, it approaches the upper surface as the upper surface adjusting part rotates and tries to overlap the circumferential surface of the tubular member when contacting, It is formed at the end of the slope trimming unit side, and in addition to overlapping with the blades of the slope trimming unit, it functions to flow the soil on the top of the trough to the slope trimming unit side. In addition, the soil at the boundary between the upper surface and the slope is leveled together with the blades of the slope trimming unit or as part of the blades of the slope trimming unit, and functions to consolidate to the inner side of the cage. As a result, the soil at the boundary between the upper and lower slopes is leveled continuously and evenly, so that the situation of discontinuity is avoided.

羽根板は上面整畦部の使用状態では筒状部材の外周に固定された状態にあるが、筒状部材に対して着脱自在に接続されていれば(請求項6)、上面整畦部の清掃に加え、損傷、もしくは摩耗した羽根板の交換に対応可能になる。具体的には羽根板と筒状部材のいずれか一方に係合部が突設され、他方にこの係合部が係合可能な被係合部が形成され、係合部と被係合部が互いに係合することにより、羽根板は前記筒状部材の側面に着脱自在に接続される(請求項7)。   The blade is fixed to the outer periphery of the cylindrical member when the upper surface adjusting portion is in use, but if it is detachably connected to the cylindrical member (Claim 6), In addition to cleaning, it is possible to replace damaged or worn blades. Specifically, an engaging portion protrudes from one of the blade plate and the cylindrical member, and an engaged portion that can be engaged with the engaging portion is formed on the other. The engaging portion and the engaged portion By engaging each other, the blades are detachably connected to the side surface of the cylindrical member (Claim 7).

係合部は羽根板の筒状部材側の面と、筒状部材の羽根板側の面のいずれかに形成され、被係合部は係合部に対向する側の面に形成される。係合部と被係合部は互いに係合したときに、羽根板を筒状部材に接続した状態を維持できる関係を持てばよく、例えば係合部が被係合部に係合したときに、係合部が羽根板の離脱の向き、すなわち筒状部材の軸方向、もしくは径方向に被係合部に係合すればよい。係合部は後述の、羽根板を筒状部材に押さえ付けるための接合部材に形成されることもあり、その場合、係合部は羽根板を貫通して筒状部材側へ突出することにより羽根板に突設されることになる。この場合、係合部は筒状部材に形成される被係合部に係合する。   The engaging portion is formed on either the surface of the blade plate on the cylindrical member side or the surface of the tubular member on the blade plate side, and the engaged portion is formed on the surface facing the engaging portion. When the engaging portion and the engaged portion are engaged with each other, it is only necessary to have a relationship capable of maintaining the state where the blade plate is connected to the cylindrical member. For example, when the engaging portion is engaged with the engaged portion. The engaging portion may be engaged with the engaged portion in the direction of detachment of the blade, that is, in the axial direction or the radial direction of the cylindrical member. The engaging portion may be formed on a joining member for pressing the blade plate against the cylindrical member, which will be described later. In this case, the engaging portion penetrates the blade plate and protrudes toward the cylindrical member side. Projected on the slats. In this case, the engaging portion engages with the engaged portion formed on the cylindrical member.

羽根板の筒状部材への接続が係合部と被係合部の係合によって行われることで、羽根板の筒状部材への接続作業と分離作業が単純化され、上面整畦部の清掃や羽根板の交換作業の効率が向上する。   By connecting the blade plate to the cylindrical member by engaging the engaging portion and the engaged portion, the connecting operation and separating operation of the blade plate to the cylindrical member are simplified, and The efficiency of cleaning and blade replacement work is improved.

係合部が被係合部に係合するのみで、羽根板が筒状部材への接合状態での安定性を確保できない場合には、羽根板は係合部において被係合部に係合した状態で、羽根板のいずれかの部分において直接、もしくは間接的に筒状部材にボルト等により接合されることにより筒状部材への接合状態での安定性が向上する。羽根板の筒状部材への接合に上記した接合部材が使用される場合には、羽根板は間接的に筒状部材にボルト等により接合されることになる。   When the engagement portion only engages with the engaged portion and the blade cannot secure stability in the joined state to the tubular member, the blade engages with the engaged portion at the engagement portion. In this state, by directly or indirectly joining the cylindrical member with a bolt or the like at any part of the blade, stability in the joined state to the cylindrical member is improved. When the above-described joining member is used for joining the blade plate to the cylindrical member, the blade plate is indirectly joined to the tubular member with a bolt or the like.

係合部が被係合部に係合したときには、係合の離脱の向きに羽根板が筒状部材から分離する可能性があるから、係合の離脱を拘束するように、例えば羽根板をその外周側からプレート等の接合部材により筒状部材側へ押さえ付けた状態で、接合部材を筒状部材にボルト接合すれば、係合の離脱が確実に防止される。接合部材は筒状部材の側面に当接、もしくは側面と端面に当接する形をし、筒状部材に対しては側面、もしくは端面にボルトが螺入することにより着脱自在に接合される。   When the engaging portion is engaged with the engaged portion, the blade plate may be separated from the tubular member in the direction of disengagement. If the joining member is bolted to the tubular member while being pressed from the outer peripheral side to the tubular member side by a joining member such as a plate, the disengagement of the engagement is reliably prevented. The joining member is in contact with the side surface of the cylindrical member, or in contact with the side surface and the end surface, and is detachably joined to the cylindrical member by screwing a bolt into the side surface or the end surface.

上面整畦部が多角柱状の筒状部材と筒状部材の側面に重なって接続される弾性を有する羽根板からなることで、筒状部材の稜線部分の外周側に位置する羽根板から畦上面を押圧するときと、側面部分の外周側に位置する羽根板から畦上面を押圧するときとで異なる圧力で畦上面を押圧することができる。   The upper surface trimming portion is composed of a cylindrical member having a polygonal column shape and an elastic blade plate connected to the side surface of the cylindrical member, so that the upper surface from the blade plate located on the outer peripheral side of the ridge line portion of the cylindrical member Can be pressed with different pressures when pressing the upper surface from the blades located on the outer peripheral side of the side surface portion.

この結果、上面整畦部がスリップ回転することにより同一地点を2通りの圧力で加圧することができ、畦上面を締め固める効果と畦を長さ方向に均等に仕上げる効果が得られるため、土質、あるいは土の含水量の差異に関係なく、畦上面の表層土を適度に圧密させながら、均質に仕上げることが可能である。   As a result, since the upper surface trimming part can rotate and slip, the same point can be pressurized with two different pressures, and the effect of compacting the upper surface of the ridge and the effect of finishing the ridge evenly in the length direction can be obtained. Or, regardless of the difference in soil water content, it is possible to finish the soil uniformly while suitably compacting the surface soil on the top surface of the ridge.

以下、図面を用いて本発明を実施するための最良の形態を説明する。   Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

図1は軸回りの回転により畦70の法面を整形する円錐台形状の法面整畦部2と、その軸方向先端に連結されて法面整畦部2と共に回転し、畦70の上面(以下、畦上面)70aを整形する上面整畦部3とを有する整畦体1を装着した畦塗り機において、上面整畦部3が多角柱状の筒状部材31と、筒状部材31の側面に重なり、筒状部材31の周方向に間隔を置いて接続される複数枚の弾性を有する羽根板32を備え、複数枚の羽根板32が全体として筒状部材31の表面を覆う状態にある整畦体1の軸方向の端面を示す。   FIG. 1 shows a truncated cone-shaped slope rectifying section 2 that shapes the slope of the ridge 70 by rotation around the axis, and is connected to the tip in the axial direction and rotates together with the slope rectification section 2. (Hereinafter referred to as heel surface) In a glazing machine equipped with an adjustment body 1 having an upper surface adjustment part 3 for shaping 70a, the upper surface adjustment part 3 includes a cylindrical member 31 having a polygonal column shape, and a cylindrical member 31. It is provided with a plurality of elastic blades 32 that overlap the side surfaces and are connected at intervals in the circumferential direction of the cylindrical member 31, and the plurality of blade plates 32 cover the surface of the cylindrical member 31 as a whole. An axial end face of a certain trimming body 1 is shown.

畦塗り機本体10は基本的に図6に示すようにトラクタの後部に3点リンクヒッチ機構を介して連結される、並列する連結フレーム11、11と、並列する連結フレーム11、11を互いに畦塗り機の幅方向に連結するヒッチフレーム12と、ヒッチフレーム12の後方に鉛直軸回りに揺動自在に連結されるオフセットフレーム13から構成される。   As shown in FIG. 6, the main body 10 is basically connected to the rear part of the tractor via a three-point link hitch mechanism, and the parallel connection frames 11 and 11 and the parallel connection frames 11 and 11 are connected to each other. The hitch frame 12 is connected in the width direction of the coating machine, and the offset frame 13 is connected to the rear of the hitch frame 12 so as to be swingable around a vertical axis.

オフセットフレーム13の前進方向後方側の先端位置からは畦塗り機本体10の幅方向に連結材14が張り出し、この連結材14とヒッチフレーム12との間に、オフセットフレーム13と平行にリンクフレーム15が架設され、双方に回動自在に連結される。オフセットフレーム13はこのリンクフレーム15とヒッチフレーム12、及び連結材14によって平行リンクを構成し、ヒッチフレーム12とオフセットフレーム13の先端位置との間に架設され、双方に連結されるシリンダ16の伸縮によってヒッチフレーム12に対してオフセット自在になる。   A connecting member 14 projects from the tip position of the offset frame 13 on the rear side in the forward direction in the width direction of the coater body 10, and the link frame 15 is parallel to the offset frame 13 between the connecting member 14 and the hitch frame 12. Is constructed and is rotatably connected to both sides. The offset frame 13 forms a parallel link by the link frame 15, the hitch frame 12, and the connecting member 14. The offset frame 13 is stretched between the hitch frame 12 and the tip position of the offset frame 13, and expands and contracts the cylinder 16 connected to both. By this, the hitch frame 12 can be freely offset.

ヒッチフレーム12のトラクタ側にはトラクタのPTO軸にユニバーサルジョイント等を介して連結されるギアボックス17が固定され、PTO軸からの動力はギアボックス17の入力軸に伝達され、入力軸からギアボックス17内の駆動軸を経てオフセットフレーム13の内部を通じ、オフセットフレーム13の先端に軸支された従動軸18に伝達される。   A gear box 17 connected to the PTO shaft of the tractor via a universal joint or the like is fixed to the tractor side of the hitch frame 12, and power from the PTO shaft is transmitted to the input shaft of the gear box 17. It is transmitted to the driven shaft 18 supported by the tip of the offset frame 13 through the inside of the offset frame 13 through the drive shaft in 17.

畦塗り機の作業機50は図7に示すように主にオフセットフレーム13先端の従動軸18と同軸で、従動軸18から動力を伝達される伝動軸55を有する駆動ボックス51に連結される整畦体1と、駆動ボックス51から整畦体1に対して進行方向前方側へ張り出し、整畦体1の整形に先だって旧畦の土砂を緩める前処理体52から構成される。前処理体52は駆動ボックス51から動力を受けて回転する畦切り爪52aを有し、作業機50の走行中、整畦体1の前方位置で畦切り爪52aが旧畦の土砂を切り崩して緩めることで、整畦体1による整形の準備をする。   As shown in FIG. 7, the work machine 50 of the wrinkle coater is coaxial with the driven shaft 18 at the tip of the offset frame 13 and is connected to a drive box 51 having a transmission shaft 55 to which power is transmitted from the driven shaft 18. It is composed of a frame 1 and a pretreatment body 52 that projects forward from the drive box 51 relative to the trimming body 1 in the direction of travel, and loosens the earth and sand of the old bowl prior to shaping of the trimming body 1. The pre-treatment body 52 has a claw claw 52a that rotates by receiving power from the drive box 51. While the work machine 50 is traveling, the claw claw 52a cuts the earth and sand of the old claw at a position in front of the trimming body 1. It is prepared for shaping by the trimming body 1 by loosening.

図6に示すように連結材14の、リンクフレーム15との連結部分には整畦体1側へ張り出すアーム53が連結され、このアーム53と、駆動ボックス51との間に、作業機50を畦塗り機本体10に対して揺動させる作業機用シリンダ54が架設され、双方に連結される。作業機50はこの作業機用シリンダ54の伸縮によって作業姿勢の制御を行う。   As shown in FIG. 6, an arm 53 projecting toward the adjusting body 1 is connected to a connecting portion of the connecting member 14 with the link frame 15, and the work machine 50 is connected between the arm 53 and the drive box 51. Is mounted on the working machine cylinder 54, which swings with respect to the main body 10 and is connected to both. The work machine 50 controls the work posture by the expansion and contraction of the work machine cylinder 54.

駆動ボックス41内には前記伝動軸55から動力が伝達される回転軸が配置され、この回転軸に整畦体1の法面整畦部2が連結される。法面整畦部2は回転軸の回転によって回転し、同時に上面整畦部3が回転する。   A rotation shaft to which power is transmitted from the transmission shaft 55 is disposed in the drive box 41, and the slope adjusting portion 2 of the adjustment body 1 is connected to the rotation shaft. The slope trimming unit 2 is rotated by the rotation of the rotary shaft, and at the same time, the upper surface trimming unit 3 is rotated.

法面整畦部2は例えば図8に示すように複数枚の扇形をした羽根板21を半径方向の直線部分で互いに連結することにより全体として円錐台形状に形成され、その先端位置である中心部には複数枚の羽根板21を連結する際の位置決めの基準になり、上面整畦部3と連結されるための連結部22が配置される。連結部22は法面整畦部2から上面整畦部3側へ突出した状態にある。   For example, as shown in FIG. 8, the slope adjusting section 2 is formed into a truncated cone shape as a whole by connecting a plurality of fan-shaped blades 21 with each other in a straight line portion in the radial direction. The connecting portion 22 is connected to the upper surface trimming portion 3 and serves as a positioning reference when connecting the plurality of blades 21 to the portion. The connecting portion 22 is in a state of protruding from the slope trimming portion 2 to the upper surface trimming portion 3 side.

連結部22の上面整畦部3側の端面には上面整畦部3とのボルト7等による連結のためのねじ孔22aが形成されており、上面整畦部3は図3−(a)に示すようにそれを軸方向に貫通するボルト7がねじ孔22aに螺入することによって連結部22に連結される。ボルト7は上面整畦部3の全長を貫通する必要はなく、上面整畦部3の先端側の端面からボルト7が単に挿通する挿通孔を形成し、その先の法面整畦部2寄りにボルト7が螺合するねじ孔を形成しておくことで、ボルト7の長さを短縮することができる。   A screw hole 22a is formed on the end surface of the connecting portion 22 on the upper surface adjusting portion 3 side for connection with the upper surface adjusting portion 3 by a bolt 7 or the like. The upper surface adjusting portion 3 is shown in FIG. As shown in FIG. 4, the bolt 7 penetrating in the axial direction is screwed into the screw hole 22a to be connected to the connecting portion 22. The bolt 7 does not need to penetrate the entire length of the upper surface trimming portion 3, and an insertion hole through which the bolt 7 is simply inserted is formed from the end surface on the front end side of the upper surface trimming portion 3, and closer to the slope surface trimming portion 2 ahead The length of the bolt 7 can be shortened by forming a screw hole into which the bolt 7 is screwed.

上面整畦部3の連結部22への連結にボルト7を使用する場合には、上面整畦部3を交換可能に連結することができる利点があるが、上面整畦部3と連結部22との連結はこの他、上面整畦部3と連結部22のいずれか一方の外周面に雄ねじを形成し、他方の内周面に雌ねじを形成しておくことで、上面整畦部3を軸回りに回転させ、直接、連結部22に交換可能に連結することもできる。   When the bolt 7 is used to connect the upper surface trimming part 3 to the connection part 22, there is an advantage that the upper surface trimming part 3 can be connected in a replaceable manner. However, the upper surface trimming part 3 and the connection part 22 are advantageous. In addition to this, by forming a male screw on the outer peripheral surface of one of the upper surface adjusting portion 3 and the connecting portion 22 and forming a female screw on the other inner peripheral surface, the upper surface adjusting portion 3 is It can be rotated around an axis and directly connected to the connecting portion 22 in a replaceable manner.

図1は前記の通り、上面整畦部3の軸方向先端側の端面を示す。ここに示すように上面整畦部3の本体を構成する筒状部材31の本体部31aは1枚の、もしくは複数枚のプレートを折り曲げ加工することにより、あるいは複数枚のプレートを組み立て、互いに溶接することにより多角柱状の形状に形成される。   FIG. 1 shows the end surface of the top surface adjusting portion 3 on the tip side in the axial direction as described above. As shown here, the main body 31a of the cylindrical member 31 constituting the main body of the upper surface trimming section 3 is formed by bending one or a plurality of plates or assembling a plurality of plates and welding them together. By doing so, it is formed into a polygonal columnar shape.

本体部31aの軸方向両側の端部、または端部と軸方向中間部には本体部31aが中空であることによる剛性不足を補うためと、羽根板32を接合するための補剛板31bが配置され、本体部31aに接合される。図面では図3−(a)に示すように上面整畦部3の軸方向先端側の端面と法面整畦部2寄りの中間部に補剛板31bを配置し、端面に配置された補剛板31bを、羽根板32を固定するために利用している。   A stiffening plate 31b for joining the blade plate 32 and an end portion on both sides in the axial direction of the main body portion 31a, or an intermediate portion between the end portion and an axially intermediate portion to compensate for insufficient rigidity due to the hollow main body portion 31a. It arrange | positions and is joined to the main-body part 31a. In the drawing, as shown in FIG. 3 (a), a stiffening plate 31b is arranged at the intermediate portion near the end surface of the top surface trimming portion 3 in the axial direction and near the slope surface trimming portion 2, and the stiffener plate 31b is disposed on the end surface. The rigid plate 31b is used to fix the blade plate 32.

補剛板31bは本体部31aに内接した状態で、または本体部31aの端面に接触した状態で、溶接やボルト接合等の手段により本体部31aに接合される。プレートからなる本体部31aの面部分は剛性を確保する上では盲板が望ましいが、軽量化を図る目的で面部分の一部に開口が形成されることもある。 The stiffening plate 31b is joined to the main body 31a by means such as welding or bolt joining while being inscribed in the main body 31a or in contact with the end surface of the main body 31a. The end face portion of the body portion 31a made of plate is desirably blind plate in order to ensure rigidity, there is also an opening is formed in a part of the end surface portions in order to reduce the weight.

補剛板31bには上面整畦部3を法面整畦部2の連結部22に連結するためのボルト7が挿通する挿通孔31cが形成される。補剛板31bにはまた、接合部材4を用いて羽根板32を本体部31aに当接させ、その状態で接合部材4を貫通するボルト5により補剛板31bに接合するためのねじ孔31dが形成されている。図1では挿通孔31を断面上の中心に関して円弧状の長孔に形成することで、ボルト7の、連結部22のねじ孔22aへの位置調整を行えるようにしている。 The stiffening plate 31b is formed with an insertion hole 31c through which the bolt 7 for connecting the upper surface adjusting portion 3 to the connecting portion 22 of the slope adjusting portion 2 is inserted. The stiffening plate 31b is also provided with a screw hole 31d for bringing the blade plate 32 into contact with the main body 31a using the joining member 4 and joining the stiffening plate 31b with the bolt 5 penetrating the joining member 4 in this state. Is formed. In FIG. 1, the insertion hole 31 c is formed in an arc-shaped long hole with respect to the center on the cross section so that the position of the bolt 7 to the screw hole 22 a of the connecting portion 22 can be adjusted.

図1は上面整畦部3の筒状部材31の断面が正八角形である場合を示しているが、筒状部材31の断面形状は必ずしも正多角形である必要はない。筒状部材31の断面が多角形状であれば、筒状部材31(多角形)の稜線部分と側面部分で畦上面70aを押圧することができるから、図2に示すように各側面の幅が相違する多角形であることもある。但し、筒状部材31が正多角形であれば、上面整畦部3の回転時に一定の時間的間隔で稜線部分と側面部分から畦上面70aを押圧することができる。   Although FIG. 1 shows the case where the cross section of the cylindrical member 31 of the top surface trimming portion 3 is a regular octagon, the cross sectional shape of the cylindrical member 31 is not necessarily a regular polygon. If the cross section of the cylindrical member 31 is a polygonal shape, it is possible to press the collar upper surface 70a with the ridge line portion and the side surface portion of the cylindrical member 31 (polygon), so that the width of each side surface is as shown in FIG. It may be a different polygon. However, if the cylindrical member 31 is a regular polygon, the upper surface 70a can be pressed from the ridge line portion and the side surface portion at a constant time interval when the upper surface trimming portion 3 rotates.

羽根板32は畦上面70aに接触したときに筒状部材31の外形に沿って弾性変形し、畦上面70aから離脱するにつれて元の形状に復元する弾性を有するポリプロピレン、ポリエチレン、ポリ塩化ビニル等の合成樹脂や鋼板等の金属材料等から成形され、筒状部材31の側面部分に着脱自在に接合される。   The slat 32 is elastically deformed along the outer shape of the cylindrical member 31 when coming into contact with the collar upper surface 70a, and is made of polypropylene, polyethylene, polyvinyl chloride or the like having elasticity that restores the original shape as it is detached from the collar upper surface 70a. It is molded from a metal material such as a synthetic resin or a steel plate, and is detachably joined to the side surface portion of the cylindrical member 31.

図面では羽根板32の筒状部材31への接続状態での安定性を確保する(羽根板32を筒状部材31から離脱させない)ために、羽根板32の外周側に上記した接合部材4を配置し、接合部材4を筒状部材31に接合することにより羽根板32を筒状部材31に着脱自在に接続している。図面では特に接合部材4に、羽根板32を筒状部材31(本体部31a)の側面に押さえ付けた状態で、筒状部材31に接続しながら、筒状部材31の端面に接合されている補剛板31bに接合する機能を持たせている。   In the drawing, in order to ensure the stability of the blade 32 connected to the tubular member 31 (to prevent the blade 32 from being detached from the tubular member 31), the joining member 4 described above is provided on the outer peripheral side of the blade 32. The vane plate 32 is detachably connected to the tubular member 31 by arranging and joining the joining member 4 to the tubular member 31. In the drawing, the joining member 4 is joined to the end face of the tubular member 31 while being connected to the tubular member 31 in a state where the blade 32 is pressed against the side surface of the tubular member 31 (main body portion 31a). A function of joining the stiffening plate 31b is provided.

図面ではまた、羽根板32と筒状部材31との着脱自在な接続作業を単純にするために、いずれか一方に、他方に係合する係合部を形成し、他方に係合部が係合する被係合部を形成している。上記のように図面では羽根板32の筒状部材31への接続を補うために接合部材4を使用していることから、接合部材4に係合部43を形成し、筒状部材31に被係合部33を形成しているが、接合部材4の係合部43が羽根板32を貫通し、筒状部材31側へ突出することで、羽根板32に係合部43を突設したことと同等になる。   In the drawing, in order to simplify the detachable connection work between the blade plate 32 and the cylindrical member 31, an engagement portion that engages with the other is formed on one side, and the engagement portion is engaged on the other side. The engaged portion to be joined is formed. As described above, in the drawing, the joining member 4 is used to supplement the connection of the blade 32 to the cylindrical member 31, so that the engaging portion 43 is formed in the joining member 4 and the tubular member 31 is covered. Although the engaging portion 33 is formed, the engaging portion 43 of the joining member 4 penetrates the blade plate 32 and protrudes toward the tubular member 31, thereby projecting the engaging portion 43 on the blade plate 32. It becomes equivalent to that.

接合部材4に係合部43を形成した場合、図3−(a)に示すように接合部材4は羽根板32の表面に重なる当接部41と、筒状部材31の端面に接合されている補剛板31bに重なる接合部42の2部分からなり、当接部41の羽根板32側の面と、筒状部材31(本体部31a)の側面のいずれか一方に、他方に係合する係合部43が突設される。図3−(b)は(a)の係合部43部分の拡大図である。ここでは上記のように接合部材4の当接部41に係合部43を形成し、筒状部材31の側面に被係合部33を形成しているが、逆の場合もある。   When the engaging portion 43 is formed on the joining member 4, the joining member 4 is joined to the contact portion 41 that overlaps the surface of the blade 32 and the end surface of the tubular member 31 as shown in FIG. It consists of two parts of the joining part 42 that overlaps the stiffening plate 31b that is engaged, and engages with either the surface on the blade plate 32 side of the contact part 41 or the side surface of the cylindrical member 31 (main body part 31a) and the other An engaging portion 43 that protrudes is provided. FIG. 3B is an enlarged view of the engaging portion 43 portion of FIG. Here, as described above, the engaging portion 43 is formed on the abutting portion 41 of the joining member 4 and the engaged portion 33 is formed on the side surface of the cylindrical member 31, but there is also the opposite case.

接合部材4に係合部43を形成したことに伴い、筒状部材31(本体部31a)の側面には係合部43が係合する被係合部33が形成される。係合部を筒状部材31に形成した場合には、羽根板32、もしくは接合部材4に被係合部が形成される。また接合部材4に係合部43を形成したことに伴い、図3−(b)に示すように羽根板32には係合部43が挿通する挿通孔32eが形成されるが、係合部43は羽根板32の筒状部材31側の面に突設されることもあり、その場合には、接合部材4の当接部41は羽根板32を単純に筒状部材31に押さえ付ける働きをする。 With the formation of the engaging portion 43 in the joining member 4, the engaged portion 33 with which the engaging portion 43 engages is formed on the side surface of the cylindrical member 31 (main body portion 31 a). When the engaging portion is formed on the cylindrical member 31, the engaged portion is formed on the blade 32 or the joining member 4. Further, along with the formation of the engaging portion 43 in the joining member 4, as shown in FIG. 3B, the blade 32 has an insertion hole 32 e through which the engaging portion 43 is inserted. 43 may protrude from the surface of the blade 32 on the side of the tubular member 31. In this case, the contact portion 41 of the joining member 4 simply presses the blade 32 against the tubular member 31. do.

係合部43は軸部43aの先端側(筒状部材31側)に頭部43bを有するピン形の形状をし、被係合部33は係合部43の頭部43bが挿通可能な挿通孔33aと、この挿通孔33aに連続し、係合部43の軸部43aが移動(スライド)自在な長孔状の溝33bを有する開口状の形状を有する。係合部43には頭部43bを有するピンやボルト等が使用される。   The engaging portion 43 has a pin shape having a head portion 43b on the distal end side (tubular member 31 side) of the shaft portion 43a, and the engaged portion 33 is inserted through which the head portion 43b of the engaging portion 43 can be inserted. The hole 33a is continuous with the insertion hole 33a, and the shaft portion 43a of the engaging portion 43 has an opening-like shape having a slot 33b that is movable (slidable). As the engaging portion 43, a pin, a bolt, or the like having a head portion 43b is used.

接合部材4の筒状部材31(本体部31a)への装着時には、係合部43の頭部43bが羽根板32に形成されている挿通孔32eを貫通し、被係合部33の挿通孔33aを貫通して軸部43aまで挿通する。その状態で軸部43aが被係合部33の溝33bに沿って移動(スライド)することで、頭部43bが溝33bに、軸方向一方側と径方向外周側へ係合した状態になり、接合部材4が筒状部材31に接続された状態になる。接合部材4の離脱時には、接続時とは逆に、軸部43aを溝33bに沿って移動(スライド)させ、頭部43bを挿通孔33aから抜き出すことにより筒状部材31から外される。 When the joining member 4 is attached to the tubular member 31 (main body portion 31 a), the head portion 43 b of the engaging portion 43 passes through the insertion hole 32 e formed in the blade plate 32, and the insertion hole of the engaged portion 33 is inserted. The shaft 33a is inserted through the shaft 33a. In this state, the shaft portion 43a moves (slides) along the groove 33b of the engaged portion 33, so that the head portion 43b is engaged with the groove 33b on one side in the axial direction and on the radially outer side. The joining member 4 is connected to the tubular member 31. When the joining member 4 is detached, contrary to the connection, the shaft portion 43a is moved (slid) along the groove 33b, and the head portion 43b is removed from the insertion hole 33a to be removed from the cylindrical member 31.

接合部材4の接合部42には接合部材4を補剛板31bに接合するためのボルト5が挿通する挿通孔42aが形成され、接合部材4はこの接合部42の挿通孔42aを貫通し、補剛板31bに螺入するボルト5によって補剛板31bに接合される。   The joining portion 42 of the joining member 4 is formed with an insertion hole 42a through which the bolt 5 for joining the joining member 4 to the stiffening plate 31b is inserted. The joining member 4 passes through the insertion hole 42a of the joining portion 42, It is joined to the stiffening plate 31b by a bolt 5 screwed into the stiffening plate 31b.

接合部材4の当接部41が羽根板32を筒状部材31の側面に押さえ付けた状態で、接合部42が筒状部材31の補剛板31bに接合されることで、羽根板32が筒状部材31に一体化し、上面整畦部3が形成される。筒状部材31に羽根板32が一体化した上面整畦部3は図3−(a)に示すように前記した法面整畦部2の連結部22に直接、連結される芯材6にボルト7により接合されることにより法面整畦部2と一体化する。 With the contact portion 41 of the joining member 4 pressing the blade plate 32 against the side surface of the tubular member 31, the joining portion 42 is joined to the stiffening plate 31 b of the tubular member 31, so that the blade plate 32 is integrated into the tubular member (3) 1, the upper surface Seiaze portion 3 is formed. As shown in FIG. 3A, the upper surface adjusting portion 3 in which the blade plate 32 is integrated with the tubular member 31 is directly connected to the connecting portion 22 of the slope adjusting portion 2 described above. By being joined by the bolt 7, it is integrated with the slope trimming unit 2.

芯材6は円筒形の本体61の内周側に軸方向に間隔を置いて配置された、剛性を確保するための複数枚の、挿通孔を有するフランジ62が接合されて形成される。土質条件によってはこの芯材6を上面整畦部3として使用することも可能である。上面整畦部3は筒状部材31の端面に接合されている補剛板31bと芯材6のフランジ62を貫通し、法面整畦部2の連結部22に形成されているねじ孔22aに到達するボルト7がねじ孔22aに螺入することにより芯材6に接合される。図3−(c)は図3−(a)に示す上面整畦部3の補剛板31b側の端面を示す。図4−(a)〜(d)は法面整畦部2に上面整畦部3が一体化した整畦体1の外観を示している。図4−(a)、(b)の矢印は整畦体1の回転の向きを示す。 The core member 6 is formed by joining a plurality of flanges 62 having insertion holes, which are disposed on the inner peripheral side of a cylindrical main body 61 at intervals in the axial direction, and for ensuring rigidity. Depending on the soil conditions, the core material 6 can be used as the upper surface trimming section 3. The upper surface trimming portion 3 passes through the stiffening plate 31b joined to the end surface of the cylindrical member 31 and the flange 62 of the core member 6, and is formed in the connecting portion 22 of the slope trimming portion 2 with a screw hole 22a. The bolt 7 reaching the position is joined to the core member 6 by screwing into the screw hole 22a. Figure 3- (c) shows the end face of the stiffening plate 3 1b side of the top surface Seiaze portion 3 shown in FIG. 3- (a). 4A to 4D show the external appearance of the trimming body 1 in which the top surface trimming section 3 is integrated with the slope trimming section 2. The arrows in FIGS. 4A and 4B indicate the direction of rotation of the trimming body 1.

上面整畦部3の羽根板32は図1に示すように筒状部材31のいずれかの側面に重なって接続される接続部32aと、これに連続し、筒状部材31の回転方向下流側に隣接する側面(羽根板32)側へ張り出す張出部32bからなり、張出部32bはその幅方向に上面整畦部3の回転方向下流側に位置する羽根板32の接続部32aを覆う長さを有する。   As shown in FIG. 1, the vane plate 32 of the upper surface trimming section 3 is connected to a connecting portion 32a that overlaps and is connected to any side surface of the cylindrical member 31, and downstream of the cylindrical member 31 in the rotational direction. The projecting portion 32b projects to the side surface (blade plate 32) side adjacent to the projecting portion 32b, and the projecting portion 32b has a connecting portion 32a of the blade plate 32 positioned downstream in the rotational direction of the upper surface trimming section 3 in the width direction. It has a covering length.

具体的には羽根板32の張出部32bはその周方向に、その羽根板32が接続されている筒状部材31の側面から回転方向下流側に隣接する側面を超える長さを有している。すなわち羽根板32の張出部32bの下流側の端部はその側に隣接する側面の稜線部分を超え、更に隣接する側面にまで跨る長さを有し、上面整畦部3の転動時には図2に示すように2枚の羽根板32が重なった状態で、進行方向前方に存在する畦上面70a上の土を羽根板32の下に巻き込みながら、スリップ回転する。   Specifically, the projecting portion 32b of the blade 32 has a length in the circumferential direction that exceeds the side surface adjacent to the downstream side in the rotational direction from the side surface of the cylindrical member 31 to which the blade plate 32 is connected. Yes. That is, the downstream end portion of the overhanging portion 32b of the blade plate 32 has a length that extends beyond the ridge line portion of the side surface adjacent to that side, and further extends to the adjacent side surface. As shown in FIG. 2, in a state where the two blade plates 32 are overlapped, the slip rotation is performed while the soil on the upper surface 70 a existing forward in the traveling direction is wound under the blade plate 32.

図2は正多角形でない筒状部材31を持つ上面整畦部3が畦上面70a上を転動しているときの様子を示す。羽根板32の張出部32bの下流側の端部がその側に隣接する側面の稜線部分を超える長さを有することで、羽根板32が畦上面70aを押圧するときには、複数枚の、図面では2枚の羽根板32が重なった状態になり、筒状部材31からの圧力は複数枚の羽根板32を介して畦上面70aに伝達されることになる。   FIG. 2 shows a state where the upper surface trimming section 3 having the cylindrical member 31 that is not a regular polygon rolls on the upper surface 70a. When the blade 32 presses the collar upper surface 70a because the downstream end of the projecting portion 32b of the blade 32 has a length exceeding the ridge line portion of the side surface adjacent to that side, a plurality of drawings Then, the two blades 32 are overlapped with each other, and the pressure from the cylindrical member 31 is transmitted to the upper surface 70a through the plurality of blades 32.

羽根板32は接続部32aにおいて上記した接合部材4によって筒状部材31の側面に重なり、断面上の中心側へ押し付けられた状態で筒状部材31に接合される。接続部32aは面で筒状部材31の平面をなす側面に重なった状態で接合されることで、接合部材4によって筒状部材31に拘束された状態にある。この状態で、張出部32bは筒状部材31の外周側へ凸となる円筒面等の曲面を形成し、筒状部材31に対して曲げ(弾性)変形可能な状態にある。   The blade 32 is overlapped on the side surface of the tubular member 31 by the joining member 4 described above at the connecting portion 32a and joined to the tubular member 31 in a state of being pressed to the center side on the cross section. The connection part 32a is in a state of being constrained by the tubular member 31 by the joining member 4 by being joined in a state where the connection part 32a overlaps with a side surface forming a plane of the tubular member 31. In this state, the overhanging portion 32 b forms a curved surface such as a cylindrical surface that protrudes toward the outer periphery of the cylindrical member 31, and is in a state where it can be bent (elastically) deformed with respect to the cylindrical member 31.

張出部32bが筒状部材31の外周側へ凸となる曲面を形成することで、張出部32bは畦上面70aに接触したときに、筒状部材31の中心からその稜線までの距離を半径とする円弧面を有する円筒に近い形状になる。   By forming a curved surface in which the overhanging portion 32b is convex toward the outer peripheral side of the tubular member 31, when the overhanging portion 32b comes into contact with the upper surface 70a, the distance from the center of the tubular member 31 to its ridgeline is increased. It becomes a shape close to a cylinder having an arc surface as a radius.

前記のように張出部32bが周方向に回転方向下流側に隣接する側面を超える長さを有することと、筒状部材31の外周側へ凸となって湾曲することで、上面整畦部3の転動時には2枚の羽根板32が重なって土を羽根板32の下に巻き込み始め、羽根板32の回転方向下流側に先端部32cが畦上面70aから離脱するまで、土を曲面で均すことになる。このとき、上面整畦部3はスリップ回転するため、畦上面70aは圧密され、表面は平滑に仕上げられる。   As described above, the overhanging portion 32b has a length exceeding the side surface adjacent to the downstream side in the rotation direction in the circumferential direction, and is curved so as to protrude toward the outer peripheral side of the cylindrical member 31. 2, the two slats 32 overlap and begin to wind the soil under the slats 32, and the soil is curved until the tip 32 c separates from the saddle upper surface 70 a on the downstream side in the rotational direction of the slats 32. I will level it out. At this time, since the upper surface trimming portion 3 rotates by slip, the upper surface 70a is consolidated and the surface is finished smooth.

上面整畦部3の転動時には上面整畦部3の断面上の中心位置が一定に保たれることで、筒状部材31の稜線部分が畦上面70aに接近し、押圧しようとするときと、側面部分が接近し、押圧しようとするときとでは、羽根板32からの押圧力に差が生じ、稜線部分が押圧しようとするときの圧力が大きくなる。   When the upper surface trimming portion 3 rolls, the center position on the cross section of the upper surface trimming portion 3 is kept constant, so that the ridge line portion of the cylindrical member 31 approaches the collar upper surface 70a and is about to press. A difference occurs in the pressing force from the blade 32 when the side surface part approaches and presses, and the pressure when the ridge line part tries to press increases.

この関係で、筒状部材31の稜線部分から羽根板32を介して畦上面70aを押圧するときに土をより大きい圧力で加圧し、側面部分から羽根板32を介して押圧するときにはそれより小さい圧力で加圧するため、上面整畦部3は2通りの圧力で畦上面70aを圧密することができる。また上面整畦部3は移動速度より大きい速度で畦上面70a上を転動(スリップ回転)するため、畦上面70aを下方へ加圧しながら、表面を均質に均すことになる。   In this relationship, the soil is pressed with a larger pressure when pressing the heel surface 70a from the ridge line portion of the cylindrical member 31 through the blade plate 32, and smaller than that when pressing through the blade plate 32 from the side surface portion. Since pressurization is performed with pressure, the upper surface trimming unit 3 can consolidate the upper surface 70a with two different pressures. Further, since the upper surface trimming section 3 rolls (slips) on the upper surface 70a at a speed higher than the moving speed, the surface is uniformly leveled while pressing the upper surface 70a downward.

図面ではまた、羽根板32の張出部32bの周方向先端部32c、すなわち回転方向下流側の先端部32cをそれ以外の張出部32bの部分より大きい曲率で湾曲、もしくは屈曲させることで、図2に示すように張出部32bの周方向先端部32cが畦上面70aから離脱するときに、この先端部32cが土を跳ね上げないようにしている。   Also in the drawing, by curving or bending the circumferential tip 32c of the overhang 32b of the blade 32, that is, the tip 32c downstream in the rotational direction with a larger curvature than the other overhang 32b, As shown in FIG. 2, when the distal end portion 32c of the projecting portion 32b is detached from the heel surface 70a, the distal end portion 32c prevents the soil from jumping up.

張出部32bは畦上面70aから離脱する直前には強制的に曲げ変形しているから、例えば張出部32bが周方向に一様の曲率を有している場合には、離脱しようとするときに、先端部32cが復元力によって急激に畦上面70aから跳ね上がることが想定される。これに対し、張出部32bの先端部32cが他の部分より大きい曲率で湾曲等することで、先端部32cが離脱するまで畦上面70a上を滑りながら畦上面70aに接触した状態を維持することができるため、土を跳ね上げることなく均すことが可能である。   Since the overhanging portion 32b is forcibly bent and deformed immediately before being detached from the collar upper surface 70a, for example, when the overhanging portion 32b has a uniform curvature in the circumferential direction, the overhanging portion 32b tends to be detached. Sometimes, it is assumed that the distal end portion 32c jumps rapidly from the heel surface 70a by the restoring force. On the other hand, the tip 32c of the overhanging portion 32b is curved with a larger curvature than the other portions, so that the state where the tip 32c is in contact with the collar upper surface 70a while sliding on the collar upper surface 70a is maintained until the tip 32c is detached. Can be leveled without jumping up the soil.

図5−(a)〜(e)は図1に示す上面整畦部3が畦上面70a上を転動し、1回転するときの様子を示す。上面整畦部3は畦上面70aから断面上の中心までの高さを一定に保持したまま回転する。上面整畦部3の断面上の中心位置は図2、図4に示すように筒状部材31の稜線部分と畦上面70aとの間に2枚の羽根板32が挟み込まれる程度の高さに設定される。   FIGS. 5A to 5E show a state where the upper surface trimming portion 3 shown in FIG. 1 rolls on the upper surface 70a and makes one rotation. The upper surface trimming section 3 rotates while maintaining a constant height from the upper surface 70a to the center of the cross section. As shown in FIGS. 2 and 4, the center position on the cross section of the upper surface trimming portion 3 is high enough to sandwich the two blades 32 between the ridge line portion of the cylindrical member 31 and the upper surface 70a. Is set.

図5−(a)は上面整畦部3を構成する筒状部材31の側面部分が畦上面70a側を向いている状況を示す。このとき、筒状部材31の側面部分は畦上面70aから浮いた状態にあり、その側面部分に固定された羽根板32の接続部32aの外周側に、その上流側の側面に固定された羽根板32の張出部32bが重なり、畦上面70aを適度の圧力で押圧する。   FIG. 5- (a) shows a situation in which the side surface portion of the cylindrical member 31 constituting the upper surface trimming portion 3 faces the side of the upper surface 70a. At this time, the side surface portion of the cylindrical member 31 is in a state of floating from the collar upper surface 70a, and the blade fixed to the upstream side surface of the connection portion 32a of the blade plate 32 fixed to the side surface portion. The overhang part 32b of the plate 32 overlaps and presses the upper surface 70a with an appropriate pressure.

筒状部材31の側面部分と畦上面70aとの間には間隔があるから、筒状部材31に関して外周側に位置する羽根板32の張出部32bは畦上面70aとの間で外周側へ凸の曲面状に弾性変形しながら土を押圧する。この状況では畦上面70a側を向いた筒状部材31の側面部分の外周側に張出部32bが位置する羽根板32の先端部32cは下流側の羽根板32の張出部32bに接触している。このとき、先端部32cは湾曲等していることで、先端が下流側の羽根板32の張出部32bに当接し、その先端部32cを有する羽根板32自身を下流側の羽根板32から突き放そうとするため、その先端部32cを有する羽根板32の張出部32bが円弧面等、外周側へ凸の曲面状に弾性変形させることに寄与している。   Since there is a gap between the side surface portion of the cylindrical member 31 and the collar upper surface 70a, the overhanging portion 32b of the blade 32 positioned on the outer circumferential side with respect to the cylindrical member 31 is directed to the outer circumferential side with the collar upper surface 70a. The soil is pressed while elastically deforming into a convex curved surface. In this situation, the tip 32c of the blade 32 where the overhang 32b is located on the outer peripheral side of the side surface of the cylindrical member 31 facing the upper surface 70a is in contact with the overhang 32b of the downstream blade 32. ing. At this time, the distal end portion 32c is curved or the like, so that the distal end comes into contact with the protruding portion 32b of the downstream blade plate 32, and the blade plate 32 itself having the distal end portion 32c is separated from the downstream blade plate 32. In order to project, the projecting portion 32b of the blade 32 having the tip portion 32c contributes to elastic deformation into a curved surface convex toward the outer periphery such as an arc surface.

図5−(b)は(a)から10°上面整畦部3が回転した状況を示す。このとき、筒状部材31の稜線部分が畦上面70aを押圧し始め、この稜線部分に押されて下流側の羽根板32を介して上流側の羽根板32の張出部32bが押し潰され、畦上面70aを(a)の状況より大きい圧力で押圧する。この状況では張出部32bにおいて畦上面70aに接触している羽根板32の上流側に位置する羽根板32の先端部32cが畦上面70aから離脱しようとしている。   FIG. 5- (b) shows a situation where the top surface trimming unit 3 has rotated 10 ° from (a). At this time, the ridge line portion of the cylindrical member 31 starts to press the collar upper surface 70a, and the ridge portion 32b of the upstream blade plate 32 is crushed through the downstream blade plate 32 by being pressed by the ridge line portion. The upper surface 70a is pressed with a pressure larger than the situation (a). In this situation, the tip 32c of the blade 32 located on the upstream side of the blade 32 in contact with the flange upper surface 70a in the overhanging portion 32b is about to be detached from the flange upper surface 70a.

図5−(c)は(b)から更に10°上面整畦部3が回転し、筒状部材31の稜線部分が筒状部材31の中心のほぼ真下に位置し、稜線部分が畦上面70a側に最も接近した状況を示す。このときには筒状部材31の稜線部分が畦上面70aに最も接近しているから、(b)に続いて畦上面70aを最も大きい圧力で押圧する。(b)から(c)へ移行する過程で、畦上面70aに接触している羽根板32の上流側にある羽根板32の先端部32cは畦上面70aから離脱しているが、上記の通り、張出部32bの周方向の先端部32cは畦上面70a上を滑りながら離脱している。   In FIG. 5C, the upper surface trimming portion 3 is further rotated by 10 ° from FIG. 5B, the ridge line portion of the cylindrical member 31 is positioned almost directly below the center of the cylindrical member 31, and the ridge line portion is the heel surface 70a. The situation closest to the side is shown. At this time, since the ridge line portion of the cylindrical member 31 is closest to the heel surface 70a, the ridge surface 70a is pressed with the greatest pressure following (b). In the process of shifting from (b) to (c), the tip 32c of the blade 32 on the upstream side of the blade 32 that is in contact with the flange upper surface 70a is detached from the flange upper surface 70a. The distal end portion 32c in the circumferential direction of the overhang portion 32b is detached while sliding on the collar upper surface 70a.

図5−(d)は(c)から更に10°上面整畦部3が回転し、筒状部材31の稜線部分が筒状部材31の中心の真下を通過し、稜線部分が畦上面70aを押圧し続けている状況を示す。(c)から(d)へ移行する間が最も畦上面70aに大きい圧力を与えるときになる。   In FIG. 5D, the upper surface trimming portion 3 is further rotated by 10 ° from FIG. 5C, the ridge line portion of the cylindrical member 31 passes just below the center of the cylindrical member 31, and the ridge line portion passes the heel surface 70a. Indicates the situation where the pressure is kept pressed. During the transition from (c) to (d), the largest pressure is applied to the upper surface 70a.

図5−(e)は(d)から更に10°上面整畦部3が回転し、(a)の状態から累積で40°回転し、(a)の直前の状況に至った様子を示す。このときには、筒状部材31の稜線部分が畦上面70aから離れ、側面部分が羽根板32を介して畦上面70aを押圧する状況へ移行しつつある。図5に示す上面整畦部3の筒状部材31は正八角形状であり、内角が135°で、外角が45°であるから、上面整畦部3は中心の回りに45°回転すれば、(a)の状態に復帰する。   FIG. 5- (e) shows a state in which the upper surface adjusting unit 3 further rotates 10 ° from (d), rotates 40 ° cumulatively from the state (a), and reaches the situation immediately before (a). At this time, the ridge line portion of the cylindrical member 31 is moving away from the heel surface 70a, and the side surface portion is shifting to a state of pressing the heel surface 70a via the blade plate 32. Since the cylindrical member 31 of the upper surface trimming section 3 shown in FIG. 5 has a regular octagonal shape, the inner angle is 135 ° and the outer angle is 45 °, the upper surface trimming section 3 is rotated by 45 ° around the center. , (A) is restored.

羽根板32の張出部32bの法面整畦部2側の端部には、図4に示すように上面整畦部3の回転方向上流側から下流側へかけて上面整畦部3側から法面整畦部2側へ接近する形状をした移行部32dが形成されている。移行部32dは主に張出部32bの端部位置から形成されるが、接続部32aと張出部32bに亘って形成されることもある。   At the end of the projecting portion 32b of the blade plate 32 on the side of the slope adjusting portion 2, as shown in FIG. 4, the upper surface adjusting portion 3 side from the upstream side to the downstream side in the rotational direction of the upper surface adjusting portion 3 A transition portion 32d having a shape approaching from the slope to the slope adjusting portion 2 side is formed. The transition portion 32d is formed mainly from the end position of the overhang portion 32b, but may be formed over the connection portion 32a and the overhang portion 32b.

法面整畦部2を構成する複数枚の羽根板21はその回転方向下流側に位置する羽根板21が上流側に位置する羽根板21の背面に重なって組み合わせられることから、相対的に上流側に位置する羽根板21が上面整畦部3寄りに位置する。この関係で、法面整畦部2の相対的に上流側に位置する羽根板21との衝突を回避するために、移行部32dは上面整畦部3の回転方向上流側から下流側へかけて上面整畦部3の軸方向の長さが大きくなり、図4−(a)〜(d)に示すように三角形状、台形状、もしくは翼状、あるいはこれらに近い形状に形成される。   The plurality of blade plates 21 constituting the slope adjusting section 2 are combined with the blade plate 21 positioned on the downstream side in the rotation direction overlapping the rear surface of the blade plate 21 positioned on the upstream side, so The blade 21 located on the side is located closer to the upper surface trimming unit 3. In this relationship, in order to avoid a collision with the blade plate 21 located on the relatively upstream side of the slope trimming part 2, the transition part 32d extends from the upstream side in the rotational direction of the upper surface trimming part 3 to the downstream side. Thus, the length of the upper surface trimming portion 3 in the axial direction is increased, and as shown in FIGS. 4- (a) to (d), it is formed in a triangular shape, a trapezoidal shape, a wing shape, or a shape close thereto.

図4−(a)、(b)、(d)中の破線は羽根板32の張出部32bと移行部32dの境界位置を示すが、移行部32dが張出部32bに連続し、張出部32bの一部として一体的に形成されている場合には、破線は実際には表れない。移行部32dは張出部32bとは別体の部品を張出部32bに連結することによっても形成される。移行部32dは図示するように法面整畦部2の羽根板21に上面整畦部3側、すなわち畦70側から重なり、例えば三角形状、もしくは台形状等の場合には、めくれを防止するために角部が落とされ、移行部32dの外形線は曲線状になる。   4- (a), (b), and (d) indicate the boundary position between the overhanging portion 32b and the transition portion 32d of the slat 32, but the transition portion 32d is continuous with the overhanging portion 32b, In the case of being integrally formed as a part of the protruding portion 32b, the broken line does not actually appear. The transition portion 32d is also formed by connecting a separate component from the overhang portion 32b to the overhang portion 32b. As shown in the figure, the transition part 32d overlaps the vane plate 21 of the slope trimming part 2 from the top trimming part 3 side, that is, the collar 70 side, and prevents, for example, turning in the case of a triangular shape or a trapezoidal shape. Therefore, the corner portion is dropped, and the outline of the transition portion 32d is curved.

上面整畦部3の回転に伴って羽根板32の張出部32bが畦上面70aに接触し、畦上面70aに押されて筒状部材31の周面(側面部分と稜線部分)に重なるときに、移行部32dも畦上面70aに押されるため、法面整畦部2の羽根板21の表面に重なろうとする。この結果、畦上面70a上の土は法面整畦部2側へ流されるため、畦上面70aと法面の境界部分における土は均等な圧力で均され、畦70の内部側へ圧密させられることになる。畦上面70aと法面の境界部分における土が均されることで、畦70の上面70aと法面との境界(面)が不連続になることがなくなる。   When the overhanging portion 32b of the blade 32 comes into contact with the heel upper surface 70a as the upper surface trimming portion 3 rotates, and is pushed by the heel upper surface 70a and overlaps the peripheral surface (side surface portion and ridge line portion) of the cylindrical member 31. Furthermore, since the transition portion 32d is also pushed by the heel surface 70a, it tends to overlap the surface of the blade plate 21 of the slope rectifying portion 2. As a result, the soil on the ridge upper surface 70a is caused to flow toward the slope leveling section 2 side, so that the soil at the boundary between the ridge upper surface 70a and the slope is leveled with equal pressure and consolidated to the inner side of the ridge 70. It will be. Since the soil at the boundary between the ridge upper surface 70a and the slope is leveled, the boundary (surface) between the upper surface 70a of the ridge 70 and the slope does not become discontinuous.
