このとき、畦上面形成体5の回動部材51は、畦側面形成体4とともに回転中心軸線aを中心として回転しつつ、軸部53がガイド溝部30に沿って移動することにより回動中心軸線bを中心として回動する。   At this time, the rotation member 51 of the heel upper surface forming body 5 rotates together with the heel side surface forming body 4 around the rotation center axis a, and the rotation of the shaft portion 53 along the guide groove 30 causes the rotation center axis. It rotates about b.

そして、図7および図8に示すように、回動部材51は、畦側面形成体4の進行方向前側下部の位置のみにおいて仮想円筒面50から外方に突出する突出状態になり、このため、突出状態の回動部材51の作用面52にて、盛土が掻き込まれつつ徐々に圧縮されて所望の畦上面が形成される。   And as shown in FIG.7 and FIG.8, the rotation member 51 will be in the protrusion state which protrudes outward from the virtual cylindrical surface 50 only in the position of the front side lower part of the advancing direction of the collar side surface formation body 4, On the working surface 52 of the projecting rotating member 51, the embankment is gradually compressed while being scraped, and a desired top surface is formed.

また、畦側面形成体4の下端位置では回動部材51が非突出状態になり、回動部材51の作用面52は仮想円筒面50に沿って位置する。   Further, the rotating member 51 is in a non-projecting state at the lower end position of the heel side surface forming body 4, and the action surface 52 of the rotating member 51 is positioned along the virtual cylindrical surface 50.

このように畦塗り機1によれば、畦形成手段7の畦上面形成体5は、回動中心軸線bを中心として回動可能で一方向への回動により仮想円筒面50から外方に突出する突出状態になり他方向への回動により仮想円筒面50から突出しない非突出状態になる複数の回動部材51を備え、畦形成作業時には、回転中心軸線aと回動部材51の下端位置との垂直距離Lが略一定になるように構成されているため、回動部材51で畦上面の土を削り取ってしまうこともなく、また畦形成手段7が上下振動することもなく、高さの安定した平坦な畦上面を形成できる。   As described above, according to the scissor coater 1, the scissors upper surface forming body 5 of the scissor forming means 7 can be rotated about the rotation center axis b, and outward from the virtual cylindrical surface 50 by rotating in one direction. A plurality of rotating members 51 that protrude into a protruding state and that do not protrude from the virtual cylindrical surface 50 when rotated in the other direction are provided. Since the vertical distance L with respect to the position is configured to be substantially constant, the rotating member 51 does not scrape the soil on the upper surface of the ridge, the ridge forming means 7 does not vibrate up and down, It is possible to form a flat top surface having a stable thickness.

また、各回動部材51は、突出状態時には仮想円筒面50からの距離が回転方向前端側から回転方向後端側に向って徐々に増大するように位置し非突出状態時には仮想円筒面50に沿って位置する円弧状の作用面52を有するため、その円弧状の作用面52にて高さの安定した平坦な畦上面を適切に形成できる。   Further, each rotating member 51 is positioned so that the distance from the virtual cylindrical surface 50 gradually increases from the front end side in the rotational direction toward the rear end side in the rotational direction when in the protruding state, and along the virtual cylindrical surface 50 in the non-projecting state. Therefore, the arcuate working surface 52 can appropriately form a flat vertical surface with a stable height.

さらに、軸部53をガイド溝部30に沿って移動させることで各回動部材51を適切に回動させることができ、回動部材51を回動させる別途のモータ等の駆動手段を必要としない。   Furthermore, each rotating member 51 can be appropriately rotated by moving the shaft portion 53 along the guide groove portion 30, and a driving means such as a separate motor for rotating the rotating member 51 is not required.

なお、例えば図示しないが、回転方向に隣り合う回動部材51間の隙間を閉塞する閉塞部材を設けるようにしてもよい。   For example, although not shown, a closing member that closes the gap between the rotating members 51 adjacent in the rotation direction may be provided.

また、回動部材51の非突出状態とは、仮想円筒面50から全く突出しない厳密な意味での非突出には限定されず、仮想円筒面50から外方へ若干突出するものでもよい。   Further, the non-projecting state of the rotating member 51 is not limited to a non-projecting in a strict sense that does not project from the virtual cylindrical surface 50 at all, and may slightly project outward from the virtual cylindrical surface 50.

さらに、上記第1の関連技術では、4つの回動部材51を備えた構成について説明したが、回動部材51の数は任意であり、例えば図9ないし図14に示す第2の関連技術のように8つの回動部材51を備えた構成でもよい。   Furthermore, in the first related technology, the configuration including the four rotating members 51 has been described. However, the number of the rotating members 51 is arbitrary. For example, the second related technology shown in FIGS. Thus, a configuration including eight rotating members 51 may be used.

図9ないし図14に示す第2の関連技術では、畦上面形成体5が8つの回動部材51を備え、回動部材51は、図5に示すものとは異なり、この回動部材51の回動支点となる左右水平方向の支軸部71を有している。支軸部71の軸芯が回動中心軸線b上に位置する。   In the second related technique shown in FIGS. 9 to 14, the upper surface forming body 5 includes eight rotating members 51, and the rotating member 51 is different from that shown in FIG. It has a support shaft portion 71 in the horizontal direction that serves as a pivot point. The axis of the support shaft 71 is located on the rotation center axis b.

また、図10および図11に示されるように、回転部材61は、図4に示すものとは異なり、軸芯が回転中心軸線a上に位置する軸部72と、この軸部72の軸方向両端に設けられた略円板状の板部73とを有している。軸部72の軸方向一端部は回転軸45に連結され、軸部72の軸方向他端部は軸受部材27にて回転可能に支持されている。板部73には、回動部材51の軸部53が挿通されこの軸部53をガイドする8つの略円弧状で長孔状のガイド部65が形成されている。各ガイド部65は、孔部62を中心とする円弧上に位置するように形成されている。また、孔部62には回動部材51の支軸部71が挿通され、回動部材51はガイド溝部30のガイドに基づいて回転部材61に対して回動中心軸線bを中心として回動可能になっている。   Also, as shown in FIGS. 10 and 11, the rotating member 61 is different from that shown in FIG. 4 in that a shaft portion 72 whose axis is located on the rotation center axis line a, and the axial direction of the shaft portion 72. And a substantially disc-shaped plate portion 73 provided at both ends. One end portion of the shaft portion 72 in the axial direction is connected to the rotating shaft 45, and the other end portion of the shaft portion 72 in the axial direction is rotatably supported by the bearing member 27. The plate portion 73 is formed with eight substantially circular arc-shaped guide portions 65 through which the shaft portion 53 of the rotating member 51 is inserted and which guides the shaft portion 53. Each guide portion 65 is formed so as to be positioned on an arc centered on the hole 62. Further, the support shaft portion 71 of the rotation member 51 is inserted into the hole portion 62, and the rotation member 51 can rotate about the rotation center axis b with respect to the rotation member 61 based on the guide of the guide groove portion 30. It has become.

なお、回転部材61は、ボルト用孔74に挿通された取付ボルト75によって取付部材47に取り付けられている。またその他の構成は第1の関連技術と同じである。   The rotating member 61 is attached to the attachment member 47 by an attachment bolt 75 inserted through the bolt hole 74. Other configurations are the same as those of the first related technology.

そして、第2の関連技術でも、上記第1の関連技術と同様、畦形成作業時には回転中心軸線aと回動部材51の下端位置との垂直距離Lが略一定であるため、回動部材51で畦上面の土を削り取ってしまうこともなく、また畦形成手段7が上下振動することもなく、高さの安定した平坦な畦上面を形成できる等の作用効果を奏することができる。   In the second related technology, as in the first related technology, the vertical distance L between the rotation center axis a and the lower end position of the rotation member 51 is substantially constant during the hook forming operation. Thus, it is possible to achieve the effects such as the formation of a flat heel surface having a stable height without scraping the soil on the heel surface and without the ridge forming means 7 vibrating up and down.

次に、本発明の畦塗り機の第1の実施の形態を図15ないし図19を参照して説明する。   Next, a first embodiment of the plastering machine of the present invention will be described with reference to FIGS.

図15ないし図19に示す第1の実施の形態では、畦上面形成体5は、畦側面形成体4の回転軸45の軸芯を通る基準中心軸線(畦側面形成体4の回転中心軸線)cを中心として円を描くように移動する偏心回転中心軸線dを中心として回転しながら、盛土体3による盛土を締め固めて畦上面を形成する略筒状の上面形成部材81を備えている。すなわち、畦上面形成体5は、基準回転中心軸線である基準中心軸線cを中心として回転すると同時にその基準中心軸線cと平行な偏心回転中心軸線dを中心として回転しながら、盛土体3による盛土を締め固めて畦上面を形成する略筒状の上面形成部材81を備えている。   In the first embodiment shown in FIG. 15 to FIG. 19, the heel surface forming body 5 is a reference central axis passing through the axis of the rotation shaft 45 of the heel side surface forming body 4 (rotation center axis of the heel side surface forming body 4). A substantially cylindrical upper surface forming member 81 is provided which forms an eaves upper surface by compacting the embankment by the embankment body 3 while rotating about an eccentric rotation center axis d that moves so as to draw a circle around c. That is, the saddle upper surface forming body 5 rotates around the reference center axis c, which is the reference rotation center axis, and at the same time rotates around the eccentric rotation center axis d parallel to the reference center axis c. A substantially cylindrical upper surface forming member 81 is formed to form the upper surface of the heel by compacting.

上面形成部材81は、図17に示されるように、側面視で略多角形状、すなわち例えば角部が湾曲状にされた略三角形状をなす外周形状に形成されている。上面形成部材81は、例えば金属板或いは合成樹脂板等にて形成されたもので、基準中心軸線cからの距離が回転方向前端側から回転方向後端側に向って徐々に増大するように位置する略円弧状の第1外周面82および基準中心軸線cからの距離が回転方向前端側から回転方向後端側に向って徐々に減少するように位置する略円弧状の第2外周面83を有している。   As shown in FIG. 17, the upper surface forming member 81 is formed in a substantially polygonal shape in a side view, that is, an outer peripheral shape having, for example, a substantially triangular shape with corners curved. The upper surface forming member 81 is formed of, for example, a metal plate or a synthetic resin plate, and is positioned so that the distance from the reference center axis c gradually increases from the front end side in the rotational direction toward the rear end side in the rotational direction. A substantially arc-shaped first outer peripheral surface 82 and a substantially arc-shaped second outer peripheral surface 83 positioned such that the distance from the reference center axis c is gradually decreased from the front end side in the rotational direction toward the rear end side in the rotational direction. Have.

また、上面形成部材81は、例えば外周形状が略三角形状をなす上面形成ローラ85と、上面形成ローラ85の被取付部86に取り付けられた筒状の可動ギア(筒状部材)87と、上面形成ローラ85の軸受部88に取り付けられた偏心軸受89とを有している。偏心軸受89は、互いに軸芯がずれた第1軸受部91と第2軸受部92とを有している。   The upper surface forming member 81 includes, for example, an upper surface forming roller 85 having a substantially triangular outer peripheral shape, a cylindrical movable gear (tubular member) 87 attached to the attached portion 86 of the upper surface forming roller 85, and an upper surface. And an eccentric bearing 89 attached to the bearing portion 88 of the forming roller 85. The eccentric bearing 89 has a first bearing portion 91 and a second bearing portion 92 whose axes are shifted from each other.

そして、畦側面形成体4の回転軸45にこの回転軸45に対して偏心して連結固定された偏心回転軸93の外周側に、上面形成ローラ85が回転可能に設けられている。すなわち上面形成部材81は、回転軸45に対して偏心した偏心回転軸93にて回転可能に支持されている。この偏心回転軸93の軸芯は偏心回転中心軸線d上に位置する。また、偏心回転軸93の先端側の挿入軸部93aが偏心軸受89の第1軸受部91内に挿入されている。   An upper surface forming roller 85 is rotatably provided on the outer peripheral side of an eccentric rotating shaft 93 that is eccentrically connected to and fixed to the rotating shaft 45 of the side surface forming body 4. That is, the upper surface forming member 81 is rotatably supported by the eccentric rotation shaft 93 that is eccentric with respect to the rotation shaft 45. The axis of the eccentric rotation shaft 93 is located on the eccentric rotation center axis d. Further, the insertion shaft portion 93 a on the distal end side of the eccentric rotating shaft 93 is inserted into the first bearing portion 91 of the eccentric bearing 89.

また一方、可動機枠13の支持アーム23の支持板部25の内面には、軸状の固定ギア(軸部材)95が固設されている。固定ギア95の外周面には基準中心軸線cを中心とする外ギア部96が形成されている。そして、上面形成部材81の可動ギア87の内周面には、固定ギア95の外ギア部96に噛み合う内ギア部97が形成されている。また、固定ギア95の先端側の挿入軸部96aが偏心軸受89の第2軸受部92内に挿入されている。   On the other hand, a shaft-shaped fixed gear (shaft member) 95 is fixed to the inner surface of the support plate portion 25 of the support arm 23 of the movable machine frame 13. On the outer peripheral surface of the fixed gear 95, an outer gear portion 96 centering on the reference center axis c is formed. An inner gear portion 97 that meshes with the outer gear portion 96 of the fixed gear 95 is formed on the inner peripheral surface of the movable gear 87 of the upper surface forming member 81. Further, the insertion shaft portion 96 a on the distal end side of the fixed gear 95 is inserted into the second bearing portion 92 of the eccentric bearing 89.

さらに、この畦塗り機1では、畦形成作業時には、基準中心軸線cと上面形成部材81の下端位置との垂直距離Lが略一定になるように構成されている。なお、その他の構成は第1の関連技術と同じである。   Further, the wrinkle coater 1 is configured such that the vertical distance L between the reference center axis c and the lower end position of the upper surface forming member 81 is substantially constant during the wrinkle forming operation. Other configurations are the same as those of the first related technology.

そして、図18および図19の(a)〜(i)に示すように、畦上面形成体5の上面形成部材81は、偏心回転軸93とともに基準中心軸線cを中心として回転すると同時に、偏心回転軸93を中心つまり偏心回転中心軸線dを中心として回転しながら、盛土を掻き込みつつ徐々に圧縮するように締め固めて畦上面を形成するが、この際、基準中心軸線cと上面形成部材81の下端位置との垂直距離Lは略一定である。   Then, as shown in FIGS. 18 and 19 (a) to (i), the upper surface forming member 81 of the collar upper surface forming body 5 rotates about the reference central axis c together with the eccentric rotation shaft 93 and simultaneously rotates eccentrically. While rotating around the shaft 93, that is, the eccentric rotation center axis d, the embankment is scraped and compacted so as to be gradually compressed to form the ridge upper surface. At this time, the reference center axis c and the upper surface forming member 81 are formed. The vertical distance L from the lower end position is substantially constant.

したがって、第1の実施の形態でも、上記各関連技術と同様、上面形成部材81で畦上面の土を削り取ってしまうこともなく、また畦形成手段7が上下振動することもなく、高さの安定した平坦な畦上面を形成できる等の作用効果を奏することができる。   Therefore, also in the first embodiment, as in each of the related techniques, the upper surface forming member 81 does not scrape the soil on the upper surface of the ridge, the ridge forming means 7 does not vibrate up and down, and the height It is possible to achieve an operational effect such as the formation of a stable flat heel surface.

なお、上面形成部材81は、側面視で略三角形状をなす外周形状に形成されたものには限定されず、例えば図20の(a)〜(c)に示す側面視で略四角形状をなす外周形状に形成されたもの(第2の実施の形態)や、図21の(a)〜(c)に示す側面視で略五角形状をなす外周形状に形成されたもの(第3の実施の形態)でも、第1の実施の形態と同様の作用効果を奏することができる。   Note that the upper surface forming member 81 is not limited to the one formed in an outer peripheral shape having a substantially triangular shape in a side view, and for example, has a substantially rectangular shape in a side view shown in FIGS. An outer peripheral shape (second embodiment) and an outer peripheral shape having a substantially pentagonal shape in a side view shown in FIGS. 21A to 21C (third embodiment) However, it is possible to achieve the same effects as those of the first embodiment.

また、上面形成部材81は、側面視で略多角形状をなす外周形状に形成されたものには限定されず、例えば図22および図23の(a)〜(i)に示す側面視で略楕円形状をなす外周形状に形成されたもの(第4の実施の形態)であっても、第1の実施の形態と同様の作用効果を奏することができる。   Further, the upper surface forming member 81 is not limited to one formed in an outer peripheral shape having a substantially polygonal shape in a side view, and is substantially elliptical in a side view shown in FIGS. 22 and 23 (a) to (i), for example. Even if it is formed in an outer peripheral shape (fourth embodiment), the same operational effects as those of the first embodiment can be obtained.

さらに、例えば図示しないが、固定ギア95および可動ギア87に代えて、固定摩擦車および可動摩擦車を利用した構成でもよい。   Further, for example, although not shown, a configuration using a fixed friction wheel and a movable friction wheel instead of the fixed gear 95 and the movable gear 87 may be used.
