Although not shown, each of the upper surface forming surface portions 44 may have a planar shape instead of a curved surface shape.

そして、各畦上面形成面部44は、回転中心軸線Ｘ側からの距離が長い第１状態と回転中心軸線Ｘ側からの距離が短い第２状態とに状態変化可能となっており、畦塗り作業の際における土との接触時には畦上面形成体25の回転中心軸線Ｘ側へ移動して第１状態から第２状態に変化する。   Each of the upper surface forming surface portions 44 can change between a first state where the distance from the rotation center axis X side is long and a second state where the distance from the rotation center axis X side is short. At the time of contact with the soil at the time, the upper surface forming body 25 moves to the rotation center axis X side and changes from the first state to the second state.

ここで、各畦上面形成面部44は、例えば弾性変形可能なプレートである弾性板45にて構成されている。弾性板45は、図６および図７に示す所定形状の樹脂板或いは金属板で、長手方向に沿った一端部に複数（例えば３つ）の貫通孔46が形成されている。   Here, each collar upper surface forming surface portion 44 is configured by an elastic plate 45 which is a plate that can be elastically deformed, for example.

That is, each elastic plate 45 is radially centered about the rotation center axis X before elastic deformation.

さらに、畦上面形成体25は、畦上面形成面部44である弾性板45と面状に当接してこの弾性板45の回転中心軸線Ｘ側への弾性板45自体の撓み弾性変形に基づく移動を規制することにより、互いに回転方向ａに隣り合う弾性板45間の段差50つまり弾性変形した一の弾性板45の自由端部45aとこの一の弾性板45と回転方向ａとは逆方向に隣り合う他の弾性板45の回転方向前端部（取付端部）との間の所定寸法の段差50を維持するストッパ部51を有している。このストッパ部51は各弾性板45に対応して設けられ、各ストッパ部51は対をなすストッパ面35a，37aにて構成されている。   Furthermore, the collar upper surface forming body 25 comes into contact with the elastic plate 45 which is the collar upper surface forming surface portion 44 in a plane and moves based on the elastic deformation of the elastic plate 45 itself toward the rotation center axis X side of the elastic plate 45. By restricting, the step 50 between the elastic plates 45 adjacent to each other in the rotation direction a, that is, the free end portion 45a of the elastic plate 45 elastically deformed, and the one elastic plate 45 and the rotation direction a are adjacent to each other in the opposite direction. It has a stopper portion 51 that maintains a step 50 having a predetermined dimension with the front end portion (attachment end portion) of the other elastic plate 45 in the rotation direction. The stopper portion 51 is provided corresponding to each elastic plate 45, and each stopper portion 51 is constituted by a pair of stopper surfaces 35a and 37a.

Each of 5 rotates.

そして、盛土体３にて土が元畦の畦側面および畦上面に盛り上げられ、回転中心軸線Ｘを中心として回転方向ａに駆動回転する畦側面形成体24の畦側面形成面部32にて土が締め固められて傾斜面状の畦側面Ｂが形成され、かつ回転中心軸線Ｘを中心として回転方向ａに駆動回転する畦上面形成体25の畦上面形成面部44にて土が締め固められて畦上面Ｃが形成される。   Then, the earth is raised by the embankment body 3 on the reed side and reed upper surface of the main reed, and the reed is formed at the reed side surface forming surface portion 32 of the reed side surface forming body 24 that rotates in the rotation direction a about the rotation center axis X. The clay is compacted to form the inclined side surface B, and the soil is compacted by the top surface forming surface portion 44 of the top surface forming body 25 that is driven to rotate in the rotation direction a about the rotation center axis X. An upper surface C is formed.

このとき、畦上面形成面部44を構成する弾性板45は、元畦の畦上面に盛り上げられた土に接触する位置で畦形成部４等の重量によって回転中心軸線Ｘ側に向って中間で折り曲がるように撓み弾性変形し、ストッパ部51のストッパ面35a，37aに当接し、回転中心軸線Ｘを中心とする仮想円に略沿った状態となる。そして、この弾性変形した一の弾性板45の自由端部45aとこの一の弾性板45と回転方向ａとは逆方向に隣り合う他の弾性板45の回転方向前端部との間には所定寸法の段差50が維持され、互いに隣り合う弾性板45同士は接触せず、非接触のままである。   At this time, the elastic plate 45 constituting the ridge upper surface forming surface portion 44 is folded in the middle toward the rotation center axis X side by the weight of the ridge forming portion 4 or the like at a position in contact with the soil raised on the upper surface of the ridge. It bends and elastically deforms so as to bend, comes into contact with the stopper surfaces 35a and 37a of the stopper portion 51, and is substantially along a virtual circle centered on the rotation center axis X. And between the free end portion 45a of this elastically deformed one elastic plate 45 and this elastic plate 45 and the front end portion in the rotation direction of another elastic plate 45 adjacent to the opposite direction to the rotation direction a, there is a predetermined amount. The level difference 50 is maintained, and the elastic plates 45 adjacent to each other are not in contact with each other and remain in non-contact.

このため、所定寸法の段差50によって土叩き効果が発揮され、弾性板45にて土が十分に締め固められる。また、弾性変形前の状態では弾性板45は回転中心軸線Ｘを中心とする仮想円の接線方向に略沿った状態であるため、弾性板45にて所望量の土が掻き込まれる。さらに、弾性板45が所定の螺旋形状であるため、弾性板45にて土が畦側面形成体24の縮径側端部に向って移動して畦側面形成体24の縮径側端部付近に所望量の土が供給される。   For this reason, the soil striking effect is exhibited by the step 50 having a predetermined dimension, and the soil is sufficiently compacted by the elastic plate 45. Further, since the elastic plate 45 is in a state substantially along the tangential direction of the virtual circle centering on the rotation center axis X before the elastic deformation, a desired amount of soil is scraped by the elastic plate 45. Further, since the elastic plate 45 has a predetermined spiral shape, the soil moves toward the reduced diameter side end portion of the heel side surface forming body 24 in the elastic plate 45, and near the reduced diameter side end portion of the heel side surface forming body 24. Is supplied with the desired amount of soil.

したがって、このような畦塗り機１によれば、水分が少ない土質等、固まり難い条件下であっても、畦上面形成体25による十分な土締め固め力が得られ、所望硬さの畦上面（肩部を含む）Ｃを形成でき、よって崩れにくい強固な畦Ａを形成できる。   Therefore, according to such a plastering machine 1, a sufficient earth compaction force can be obtained by the kite surface forming body 25 even under difficult conditions such as soil with little moisture, and the kite upper surface having a desired hardness can be obtained. C (including the shoulder) can be formed, and thus a strong ridge A that is difficult to collapse can be formed.

なお、上記一実施の形態では、畦上面形成面部44が螺旋形状面体である弾性板45にて構成されたものについて説明したが、例えば図９に示す他の実施の形態のように、畦上面形成面部44が弾性変形不可能な螺旋形状面体である非弾性板（剛性板）55にて構成されたものでも、同様の作用効果を奏することができる。   In the above embodiment, the case where the heel upper surface forming surface portion 44 is configured by the elastic plate 45 which is a spiral-shaped face body has been described. However, as in the other embodiment shown in FIG. 9, for example, Even if the formation surface portion 44 is configured by a non-elastic plate (rigid plate) 55 that is a spiral-shaped surface body that cannot be elastically deformed, the same effect can be obtained.

この図９に示すものでは、非弾性板55の回転方向前端部が被取付板部41に弾性変形可能な連結弾性体56を介して取り付けられ、非弾性板55の回転方向後端部が自由端部55aとなっている。連結弾性板56は、第１板部57および第２板部58を有する略Ｌ字状のもので、第１板部57が被取付板部41にボルト等からなる取付手段47にて取り付けられ、第２板部58が非弾性板55の回転方向前端部にボルトおよびナット等からなる取付手段59にて取り付けられている。   9, the front end portion in the rotational direction of the inelastic plate 55 is attached to the attached plate portion 41 via a connecting elastic body 56 that can be elastically deformed, and the rear end portion in the rotational direction of the inelastic plate 55 is free. It is an end 55a. The connecting elastic plate 56 is substantially L-shaped having a first plate portion 57 and a second plate portion 58, and the first plate portion 57 is attached to the attached plate portion 41 by attachment means 47 made of bolts or the like. The second plate portion 58 is attached to the front end portion in the rotational direction of the inelastic plate 55 by attachment means 59 made of bolts and nuts.

そして、この図９に示すものでは、ストッパ部51が、畦上面形成面部44である非弾性板55と面状に当接してこの非弾性板55の回転中心軸線Ｘ側への連結弾性板56の撓み弾性変形に基づく移動を規制することにより、互いに回転方向ａに隣り合う弾性板45間の段差50を維持する。   9, the stopper portion 51 is brought into contact with the non-elastic plate 55 which is the upper surface forming surface portion 44 in a planar shape, and the elastic plate 56 which is connected to the rotation center axis X side of the non-elastic plate 55 is provided. The step 50 between the elastic plates 45 adjacent to each other in the rotation direction a is maintained by restricting the movement based on the bending elastic deformation.

また、いずれの実施の形態においても、ベース部33の外周面に被取付板部41を溶接等により取り付けた構成には限定されず、例えばベース部33の外周側に被取付板部41を一体に形成した構成等でもよい。   In any of the embodiments, the configuration is not limited to the configuration in which the mounting plate portion 41 is attached to the outer peripheral surface of the base portion 33 by welding or the like. For example, the mounting plate portion 41 is integrated with the outer peripheral side of the base portion 33. The structure etc. which were formed in may be sufficient.

さらに、畦上面形成面部44の数は８つには限定されず、６つや１０以上でもよく、任意である。   Furthermore, the number of the upper surface forming surface portions 44 is not limited to eight, but may be six or ten or more, and is arbitrary.
