Description

【0001】
【産業上の利用分野】
本発明は、移植機または播種機の後部に装置して使用する高畦成形装置の改良に関する。
【0002】
【従来の技術】
移植機または播種機により当該作物の苗または種子を浅植えまたは浅播きした直後に、ディスクコルターで両側から土寄せして高畦とし、その高畦を高畦成形体で鎮圧成形する高畦成形装置は、既に実公昭58−45526号公報,実開平61−56832号公報等に記載されていて公知である。
【0003】
【発明が解決しようとする課題】
これら公知の高畦成形装置には次のごとき課題がある。
(1) ディスクコルターによる土寄せ量は、該高畦成形装置の進行方向に対するディスクコルターの開度によって調整設定されるものであるところ、そのディスクコルターの下周頂部と高畦成形体の下周頂部が上記進行方向一直線上に揃っていないこと、換言すると、左右に食い違って位置すること等に起因し、効率のよい高畦の鎮圧成形ができない。このことは例えば、ディスクコルターが土寄せした土の全量が高畦成形体による高畦の鎮圧成形に常に寄与しているとは限らないということを意味する。
【0004】
(2) 高畦成形体は、ディスクコルターが土寄せし形成した高畦の両側面を鎮圧するだけであるために、移植苗または播種種が列設位置するその高畦の上面中央の土が盛り上がって緩んだ状態となり、苗または種の前後に空隙を生じるとか、その緩んだ土が風で飛散してしまう。
【0005】
(3) 隣り合う高畦の間に残土を畦状に残してしまう。すなわち、例えば、多畦用高畦成形装置では、隣り合う各別の畦の形成に関与するディスクコルター同士の下周間、および同じく各別の畦の鎮圧成形に関与する高畦成形体同士の下周間を通過した土が、隣り合う高畦の間に畦状に残る。単畦用高畦成形装置においても同様である。
【0006】
(4) 該高畦成形装置を装置した移植機または播種機は、トラクター等の牽引車両により牽引され走行するものであるが、その牽引車両の車輪と同じ軌跡上を通ることになるディスクコルターが、該車輪で踏圧された土によって浮き上がり所期の土中深さに達しないことがあり、十分な土寄せ機能を発揮できない。
【0007】
本発明の目的は、ディスクコルターの開度に関係なく、そのディスクコルターが土寄せした土の全量で形成された高畦を鎮圧成形すること、高畦の上面中央を踏圧して土の緩みをなくすこと、隣り合う高畦の間に畦状の土を残さないこと、ディスクコルターを牽引車両の車輪で踏圧された土に対しても所期の深さまで到達させ、該ディスクコルターに十分な土寄せ機能を発揮させること、等を実現することにある。
【0008】
【課題を解決するための手段】
請求項1の発明高畦成形装置Aは、土寄せして高畦h,h′を形成するディスクコルターa,a,a′,a′と、これらのディスクコルターの後方において、上記高畦h,h′を鎮圧成形する高畦成形体b,b、b′,b′とを備え、さらに、上記各ディスクコルターを、その下周頂部dが、該各ディスクコルターの開度を変えたときにおいても、上記各高畦成形体の下周頂部eと、本装置Aの進行方向一直線f,f′上に位置するように支承してなるものである。

【0011】
請求項4の発明高畦成形装置Aは、上記ディスクコルターおよび高畦成形体のほかに、高畦h,h′の上面を踏圧する畦上面踏圧輪g,g′を、上記高畦成形体の後方に設けてなる。
その畦上面踏圧輪g,g′の周面形状は、平坦面のほか凹状面とすることもでき、前者によれば高畦h,h′の上面を下方外側に向かう押圧力で、後者によれば該高畦h,h′の上面を下方内側に向かう押圧力でそれぞれ踏圧することができるもので、いずれの形状にするから土質等に応じて適宜決定できる。
上記畦上面踏圧輪g,g′は、支持部材13,13′の遊端側に軸支連結した回動枠19,19′の遊端側に軸架し、かつ、下方に向けて弾圧付勢すると、その機能を十分に発揮できて好適である。
【0012】
請求項8の発明高畦成形装置Aは、上記ディスクコルターおよび高畦成形体のほかに、上記高畦h,h′の間に畦状に残ろうとする土jを均す残土均し部材iを設けてなる。
上記残土均し部材iは、回動枠19,19′に、下方に向けて弾圧付勢するように架設ると、その機能を十分に発揮できて好適である。
【0013】
請求項10の発明高畦成形装置Aは、上記ディスクコルターおよび高畦成形体のほかに、しかも、そのディスクコルターの前方であって、かつ、本装置Aが牽引されることになる牽引車の車輪の軌跡に一致する位置に耕起爪片k,k′を設置してなる。
この耕起爪片k,k′は、移植機または播種機の機枠1の後端に取り付けた支持部材29,29′の下端に取り付けることによって簡単に構成できる。
【0014】
【作用】
請求項1〜11の高畦成形装置は、ディスクコルターが土寄せして高畦を形成するとともに、その両側面を高畦成形体が鎮圧成形するにあたり、高畦の高さを、ディスクコルターの開度を調整して土寄せ量を変えることにより適宜定めることができるものであるが、その開度の如何にかかわりなく、各ディスクコルターの下周頂部dは左右に変位することなく、常に、高畦成形体の下周頂部eと本装置の進行方向の同一直線上に位置するので、換言すると、両下周頂部が左右方向に食い違いを生じることがないので、高畦成形体は、ディスクコルターが土寄せした土の全量よる高畦の効率のよい鎮圧成形を行うことができる。
【0015】
請求項4〜7の高畦成形装置によれば、畦上面踏圧輪が高畦の上面を踏圧することによって、その上面の土を適宜締め付け、土が風で飛散するようなことがないようにできる。
【0016】
請求項8,9の高畦成形装置は、残土均し部材が、隣り合う高畦の間に残ろうとする土を均すことができる。
【0017】
請求項10,11の高畦成形装置は、一般にディスクコルターのうちの特に左右外側に位置するディスクコルターは、本装置Aを牽引する牽引車両の車輪と同じ軌跡上を運行されるが、その牽引車の車輪が踏圧したところを耕起爪片が耕起するので、上記左右外側のディスクコルターが浮き上がることなく土中所要深さに達し所期の土寄せを行うことができる。
【0018】
【実施例】
以下には、本発明の実施例を移植機に装置して示す2畦用の高畦成形装置について詳しく説明する。
【0019】
この2畦用の高畦成形装置Aは、同じく2畦用の移植機Bの後部に装置されている。
その移植機Bは、機枠1の上面中央に苗供給装置2を、同後側に苗台3を、下面中央に作溝器4を、さらに、この作溝器4と駆動輪5との間に回転植付け器6を、それぞれ2畦分備えてなる公知のもので、苗台3上の移植苗を手作業または適宜の自動手段で苗供給装置2に供給することによって、回転植付け器6が、作溝器4が作溝した畦溝に所要の植付け間隔で、2畦浅植えすることができる。
【0020】
多畦用高畦成形装置Aにおいて、7,7′は上記移植機Bの機枠1の後端に基端を固定した左右一対のブラケット、8,8′はそのブラケット7,7′に貫通支承した横架材、9,9は横架材8の内端と外端に,9′,9′は横架材8′の内端と外端に、それぞれ直状上側部を上下動および回動させることができるようにして挿通した縦軸杆である。
10は横架材8,8′の内外両端部にそれぞれ水平に螺合挿通し、先端を各縦軸杆の上記直状上側部に圧接することにより、その各縦軸杆を横架材8,8′に対し固定支持する押しボルトで、各縦軸杆の上下動および回動はこの押しボルト10を緩めた状態で行う。
【0021】
a,a、a′,a′は、上記縦軸杆9,9、9′,9′の偏倚下側部に、aとa、a′とa′をそれぞれ内向きにして軸支したディスクコルターで、これらのディスクコルターは、その開口周面a1 を(図4)、それぞれの縦軸杆の上記直状上側部の軸延長線cを含む垂直面と一致させ、該垂直面内で回転するように軸支されているもので、その軸支は、突出軸11を各縦軸杆の下端の軸受け筒12に挿嵌することによって行っている。
【0022】
ディスクコルターaとa、a′とa′の本装置Aの進行方向(矢印(イ))側すなわち前側の開度を大とすると土寄せ量が多くなるからより高い畦を形成でき、反対にその開度を小にすると土寄せ量が減り畦が低くなるものであり、その開度調整は、押しボルト10を緩めた状態で、各縦軸杆を、その上端に適宜のアジャストスパナ(図示していない)を嵌めて回動することにより行うものであるが、上記のようにディスクコルターの開口周面a1 を縦軸杆の軸延長線cを含む垂直面と一致させているので、各ディスクコルターの下周頂部dは、該ディスクコルターの開度の如何によって変位することなく、当初設定位置を維持する。
【0023】
b,b、b′,b′は、基端を上記ブラケット7,7′に回動自在に軸支連結した細長板状の支持部材13,13′の各遊端であって、しかも、ディスクコルターa,a、a′,a′より後方の位置に、bとb、b′とb′をそれぞれ内向きにして軸支した高畦成形体で、これら各高畦成形体は、その下周頂部eを、上記各ディスクコルターの下周頂部dと、本装置Aの進行方向(矢印(イ))に走る一直線f,f′上に設置している(図3)。
【0024】
14,14′はブラケット7,7′に設けた小ブラケット、15,15′は上端側を小ブラケット14,14′の横架軸16,16′に摺動自在に貫通支承するとともに下端を上記支持部材13,13′のほぼ中央に軸支した調整杆であり、17,17′はストッパー18,18′と小ブラケット14,14′との間において調整杆15,15′に巻装したコイルバネである(図1,2)。
【0025】
したがって、上記各高畦成形体は、支持部材13,13′を介しコイルバネ17,17′によって下方に弾圧付勢され、かつ、その付勢力はストッパー18,18′の固定位置を変えることにより適宜調整できる。
【0026】
g,g′は畦上面踏圧輪で、これらは、基端を上記支持部材13,13′に回動自在に軸支連結した平面凸形の回動枠19,19′の各遊端側であって、しかも上記各高畦成形体の後方至近位置に軸架されている。
畦上面踏圧輪g,g′の周面形状を、図3,6に示すような平坦面にすると、上記高畦成形体が鎮圧成形した高畦h,h′の上面を下方外側に向かう押圧力で踏圧でき、また、図7に示すように凹状面とすると、高畦h,h′の上面を下方内側に向かう押圧力で踏圧できるもので、いずれの形状を採用するかは土質等を考慮し適宜決定すればよい。
高畦成形体が高畦h,h′の両側面を鎮圧することにより盛り上がり緩んだ状態の上面中央が、これら畦上面踏圧輪g,g′による踏圧によって締まるから風でその上面の土が飛散するようなことがなくなるものである。
【0027】
20,20′は上記小ブラケット14,14′に重合設置した小ブラケット21,21′に基端を回動自在に軸支した調整杆で、その遊端側を、回動枠19,19′に起立したブラケット22,22′の横架軸23,23′に摺動自在に貫通支承している。
【0028】
24,24′はストッパー25,25′と小ブラケット22,22′との間において調整杆20,20′に巻装したコイルバネで、該コイルバネ24,24′によって、踏圧輪g,g′は下方に弾圧付勢され、かつ、その付勢力はストッパー25,25′の固定位置を変えることにより適宜調整できる。
【0029】
iは畦上面踏圧輪g,g′の間であって、そのやや後方位置に支持した平面V字形の残土均し部材で、上記回動枠19,19′に跨架した連結桟26に軸支した腕杆27の遊端に上記V字形の頂部を固着している。
この残土均し部材iは、高畦成形体が鎮圧成形した高畦h,h′の間に残ろうとする畦状土j(図5)を均す作業を行うものである。
【0030】
k,k′は、上記移植機Bの機枠1の後端の左右に固定したブラケット28,28′に基端を固定した支持部材29,29′の下端に取り付けた耕起爪片である。
この耕起爪片k,k′は、上記ディスクコルターのうちの左右外側に位置するディスクコルターa,a′の前方、また、移植機Bを牽引するトラクター等の牽引車両の車輪が通過する軌跡上に、上記の支持部材29,29′によって支持されているもので、牽引車両の車輪が踏圧した土を耕起し、上記ディスクコルターが浮き上がることなく土中所要深さに達し、所期の土寄せが効果的に行われるようにするためのものである。
【0031】
m,m′は、ディスクコルターaとa、a′とa′の各間に位置するようにして、上記支持部材13,13′に装架した移植苗の埋没防止枠で、この埋没防止枠m,m′は、移植機Bの回転植付け器6によって浅植えされた移植苗が、各ディスクコルターによる土寄せにより、土を被りすぎ高畦の中に必要以上に埋没してしまうのを防止する。
【0032】
かかる構成の本装置Aによれば、移植機Bが回転植付け器6によって移植苗を2畦浅植えするのにともない、その2畦に対し、ディスクコルターaとa、a′とa′が土寄せして高畦h,h′を形成するとともに、その高畦h,h′の両側面を高畦成形体bとb、b′とb′が鎮圧成形し(図5)、さらに、その高畦h,h′の上面を畦上面踏圧輪g,g′が踏圧する(図6,7)。
これによって、両側面および上面を所期どおりに締め付けた高畦h,h′とすることができるもので、特に、畦上面踏圧輪g,g′による高畦h,h′の上面の締め付けにより土が浮き上がったままとなることがなく、したがって、風で飛散するようなことがない。
【0033】
上記において、高畦h,h′の高さは、前述のとおりディスクコルターの開度を調整して土寄せ量を変えることにより適宜定めることができるものであるが、その開度の如何にかかわりなく、各ディスクコルターの下周頂部dは左右に変位することなく、常に、高畦成形体の下周頂部eと本装置Aの進行方向の同一直線f,f′上に位置するので、換言すると、両下周頂部d,eが左右方向に食い違いを生じることがないので、高畦成形体は、ディスクコルターが土寄せした土の全量よる高畦の効率のよい鎮圧成形を行うことができる。
【0034】
また、ディスクコルターのうちの左右内側に位置し隣接するディスクコルターa,a′の下周間、および、高畦成形体のうちの左右内側に隣接位置する高畦成形体b,b′の下周間を通過する土によって、高畦h,h′の間に土jが畦状に残ろうとするが、それは、残土均し部材iによって均してしまうことができるものである。
【0035】
上記ディスクコルターのうちの左右外側に位置するディスクコルターa,a′は、移植機Bを牽引する牽引車両の車輪と同じ軌跡上を運行されるが、その牽引車の車輪が踏圧したところを耕起爪片k,k′が耕起するので、上記左右外側のディスクコルターa,a′は浮き上がることなく土中所要深さに達し所期の土寄せを行うことができる。
【0036】

[Industrial applications]
TECHNICAL FIELD The present invention relates to an improvement of a high ridge forming device used as a device installed at the rear of a transplanter or a seeder.
[0002]
[Prior art]
Immediately after the seedlings or seeds of the crop are shallowly planted or sowed with a transplanter or sowing machine, a high ridge molding device that forms a high ridge by cultivating the soil from both sides with a disc coulter and pressing down the high ridge with a high ridge molding has already been implemented. It is well known as described in JP-B-58-45526, JP-A-61-56832.
[0003]
[Problems to be solved by the invention]
These known high ridge forming apparatuses have the following problems.
(1) The amount of burrowing by the disc colter is to be adjusted and set by the degree of opening of the disc corter with respect to the traveling direction of the high ridge forming device, and the lower peripheral top of the disc colter and the lower peripheral top of the high ridge molded body are as described above. Due to the fact that they are not aligned on the straight line in the direction of travel, in other words, they are staggered on the left and right, etc., efficient repressing molding of high ridges cannot be performed. This means, for example, that the entire amount of soil collected by the disc coulter does not always contribute to the suppression of high ridges by the high ridge molding.
[0004]
(2) Since the high row molding only suppresses both sides of the high row formed by the disc colter, the soil at the upper center of the high row where the transplanted seedlings or sowing seeds are lined up is loosened. It becomes a state, and a void is formed before and after a seedling or a seed, or loose soil is scattered by wind.
[0005]
(3) The residual soil is left in a ridge shape between adjacent high ridges. That is, for example, in a multi-row high ridge forming apparatus, the lower rim between the disc coulters involved in the formation of each adjacent ridge and the lower ridge between the high ridge molded bodies also involved in the pressure reduction molding of each different ridge. The soil that has passed between them remains in a row between adjacent high ridges. The same applies to a single-row high-ridge forming apparatus.
[0006]
(4) The transplanter or the seeder equipped with the high row molding device is towed by a towing vehicle such as a tractor and travels, but a disc colter that passes along the same trajectory as the wheels of the towing vehicle, In some cases, the soil is lifted by the soil depressed by the wheels and does not reach the intended depth of the soil, so that a sufficient soil collecting function cannot be exhibited.
[0007]
The object of the present invention is to suppress the molding of the high ridge formed by the entire amount of soil that the disc colter has laid, regardless of the degree of opening of the disc colter, to eliminate the looseness of the soil by stepping on the center of the upper surface of the high ridge, Do not leave ridge-shaped soil between adjacent high ridges, make the disc colter reach the expected depth even for soil trampled by the wheels of the towing vehicle, and make the disc corter have a sufficient burrowing function That is, to realize such things.

It becomes.
The peripheral surface shape of the ridge upper surface pressing wheels g, g 'can be a flat surface or a concave surface. According to the former, the upper surface of the high ridges h, h' is pressed downward and outward, and the latter is deformed by the latter. For example, the upper surfaces of the high ridges h and h 'can be stepped down with a pressing force directed inward and downward, and the shape can be appropriately determined according to the soil or the like since the shape is any shape.
The ridge upper surface pressing wheels g, g 'are mounted on the free ends of the rotating frames 19, 19' pivotally connected to the free ends of the support members 13, 13 ', and are elastically pressed downward. It is preferable that the function be fully exerted.
[0012]
