【発明の属する技術分野】
本発明は、苗載台の下端側に設けたエプロンに対して苗載台を左右往復動させながら、エプロンに設けた掻取口から苗植付爪でマット苗を掻取って圃場面に植付ける移植機に関する。
【０００２】
【従来の技術】
従来、この種の移植機の苗載台の構造は、複数の苗載面と、複数条分のマット苗の間を１条毎に縦方向に仕切るリブとをリベット等で接合して一体状に構成していた。
【０００３】
【発明が解決しようとする課題】
従って、移植機で苗の植付作業を長時間行っている内に、苗載台の左右方向への移動により苗載台の下端部分である各条毎のリブの下端と、苗載台の下方にあるエプロンとの隙間にマット苗とエプロン１５との摩擦で剥がれ落ちたマット苗の床土等が挟まれ、リブの下端部が摩耗することによって隙間が拡大し、横移動中のマット苗がその拡大した隙間に引っ掛かって、マット苗の下端部が破損するため、磨耗したリブを交換する場合があった。
しかし、従来の移植機ではリブが苗載面と一体状に接合して形成されていたため、これの交換作業は容易ではなく、かなりの時間を取られると共に、コスト的にも不利である等の不具合があった。
本発明の目的は、上記従来の不具合を改善する点にある。
【０００４】
【課題を解決するための手段】
上記目的を達成するため、本発明においては、左右のマット苗の間を仕切るリブを縦方向に複数設けた苗載台と、該苗載台の下端側に複数の掻取口を有したエプロンを設け、前記苗載台をエプロンに対して左右往復動させながら、前記掻取口から苗植付爪でマット苗を掻取って圃場に植付ける移植機において、前記エプロンに対向するリブの下端部に、リブ本体に連続するリブピースを着脱可能に装着したことを特徴とする。
【０００５】
又、苗載台のリブを、その上壁部において左右に分割した半割リブの突き合わせで構成すると共に、エプロンに対向する左右の半割リブの下端部を突き合わせた状態で、両者をリブピースで結合することを第２の特徴とする。
【０００６】
【発明の実施の形態】
本発明の実施の形態の一例を以下乗用田植機に実施した図面に基づいて説明する。図１は乗用田植機の全体側面図、図２は同上平面図であり、通常の田植機と同様に、１は前後に一対の車輪２，２、３，３を備え、後部には上下揺動する平行リンクを介して田植装置４を装着した走行機体であって、該走行機体１の前部にはエンジン５，予備苗載台６，運転操作用のハンドル７等を配置し、中央部には運転者の座席８を、また、後部に備えた上記田植装置４には、植付フレーム９，苗載台１０，苗植付装置１１・・，フロート１２・・等が備えられている。
【０００７】
更に、１４は苗載台１０の上部後端側に延長して取付けた延長苗載台であり、１５は苗載台１０の下端側に設けたエプロン、１６は図２で明白なように、エプロン１５の左右両側方への突出部をガードするエプロンガード、２２はエプロン１５に設けた掻取口、１８は苗載台１０上のマット苗を前方縦方向に送るゴムベルト、１９は一定の掻取軌跡を描いて回転する複数の苗植付爪２０・・の軌跡をガードするプランタガード、２１は線引きマーカである。
【０００８】
即ち、上記諸装置を備えた本発明の田植機においては、苗載台１０上の各単位苗載面２３・・上に各１条分のマット苗を載置して苗載台１０が上記エプロン１５に対して左右方向へ往復動すると同時に、各苗植付爪２０・・により、エプロン１５の掻取口２２から、マット苗を１株毎に掻取って、田面上に植付けて行くものである。
そして、図示を省略したが、各苗植付爪２０・・を支持するケース上面に設けた取付座にエプロン支持プレートを架設し、該エプロン支持プレートに対してエプロン１５を上下摺動可能に設け、エプロン１５でスライドピースを介して左右方向へ摺動可能に苗載台１０を支持している。
従って、上記１株（単位株）分の掻取量の調節は、従来のエプロン１５のみの上下移動ではなく、エプロン１５と苗載台１０とを苗植付爪２０の掻取軌跡に対して一体的に上下移動させるようにしているものである。
【０００９】
次に、図３は苗載台部分の側面図、図４は図３要部の拡大側面図であって、２４は上記苗載台１０の左右両端部の単位苗載面２３・にのみ設けられた植付け条数調節用の苗送りストッパであり、２５は苗押えホルダであって、これには上記マット苗が走行機体１の振動等で浮き上がったりしないように、弾力を有する杆状の苗押え１７・・が、各単位苗載面２３毎に後方から前方の苗掻取部分の近傍に迄亘って複数本づつ装着されている。
また、２６は苗載台１０を縦方向に各条毎に仕切るリブであり、該リブ２６のエプロン１５に対向した下端部には、リブ本体２７に連続するリブピース３６を着脱可能に装着しており、その詳細については次の図５にて説明する。
【００１０】
図５はリブ下端側の構成を示す説明用斜視図であって、２８は一方の半割リブ２７ａと他方の半割リブ２７ｂとを左右に備えた一対の苗載台プレートであり、一対の半割リブ２７ａ，２７ｂの上壁側に複数個の係合突起２９・・とこれに係合する係合受部３０・・とを形成している。
さらに、これら一対の半割リブ２７ａ，２７ｂはその下端部に、夫々内部にボルト３１とナット３２とを保持する半分づつの空間３３部分がくり抜かれた左右対称形の、一対の嵌合突片３４ａ，３４ｂが夫々一体状に設けられている。
また、苗載台１０の両端部分の苗載枠１０ａ，１０ｂは夫々片側の半割リブ２７ａ及び嵌合突片３４ａ（又は２７ｂ及び３４ｂ）のみを備えている。
そして、苗載台プレート２８・・を左右並列状に配置し、その両端に苗載枠１０ａ，１０ｂを配置して、隣接した一方の半割リブ２７ａに形成された係合突起２９と、他方の半割リブ２７ｂに形成された係合受部３０とを係合させてリブ本体２７を構成すると共に、各苗載台プレート２８・・と苗載枠１０ａ，１０ｂを連結して苗載台１０を構成する。
【００１１】
一方、前記リブピース３６は、上記一対の嵌合突片３４ａ，３４ｂを突き合わせた状態で嵌合する穴部３６ａを設けた合成樹脂材料等による箱型の一体物で形成し、リブピース３６の上部の取付面３６ｂには、上記ボルト３１が挿通されるように穴部３６ｃが穿設されていて、リブピース３６を両嵌合突片３４ａ，３４ｂに被嵌して取付ける際に、予め突き合わせた両嵌合突片３４ａ，３４ｂの空間３３内部にナット３２を入れておき、リブピース３６を被嵌後に上方の穴部３６ｃからボルト３１を挿通して締めつけることによりこれらが固定される。
【００１２】
従って、本発明のものでは、共通部品である複数の苗載台プレート２８・・を組合わせることにより、条数の異なる各種の苗載台１０を安価で簡単に構成出来るばかりか、それらの各苗載台プレート２８・・の連結は、リブ本体２６の上壁部にある複数箇所の係合突起２９・・と係合受部３０・・とによる係合連結部３７・・と、各リブ本体２７下端部分のリブピース３６・・の複数箇所で夫々連結される。
このものでは、苗載台１０を構成する部品点数を少なくすることができると共に、苗載面２３に連結部を形成していないため、マット苗と連結部との引っ掛かりを防止することができる。
なお、３８は片側の半割リブ２７ｂ頂部に他方側の半割リブ２７ａ頂部を覆うように形成されたカバー部である。
【００１３】
本発明の移植機は、以上のような構成よりなっており、田植装置４による苗の植付作業時に、苗載台１０上にマット苗を搭載して植付を開始すると、苗載台１０はエプロン１５に対して左右方向へ往復動する。そしてこの間に上下に植付作動する苗植付爪２０・・によりマット苗を１株分毎に掻取って圃場面に植え付ける。
この際、苗植付爪が横一列分の苗を順次掻取って行き、端部の苗を掻取った時、ゴムベルト１８・・が瞬時に縦方向下方へ一株の掻取量分回動してマット苗をエプロン１５側に繰出し、苗載台１０が今度は反対方向に横移動しながら、苗植付爪２０・・により同様の作用を繰返す。
そして、上記１株分の苗の掻取量を変更したい時、本発明の場合には、別途の操作レバー（図示せず）により、苗載台１０とエプロン１５とを苗植付爪２０の掻取軌跡に対して一体的に上下移動させて行う。
【００１４】
このようにして、苗の植付作業を行う場合、各リブ本体２７・・に装着されたリブピース３６・・は、エプロン１５との隙間を極力小さくして、隣接条との間を仕切る事によりエプロン１５とマット苗下端の摺動抵抗によって、マット苗の下端部分がリブとエプロン１５との間に挟みこまれて破損するのを防止する。
しかしながら、移植機を長時間使用している間に、リブ２６のリブピース３６の下端部とエプロン１５との隙間に、マット苗とエプロン１５との摩擦で剥がれ落ちたマット苗の床土等が挟まれ、リブピース３６が徐々に磨耗して隙間が拡大してくる。
このような時にはリブピース３６を新しいものと交換する必要が生ずる。
【００１５】
即ち、リブピース３６を交換する際には、エプロン１５から苗載台１０を多少浮かせてリブピース３６下端とエプロン１５との間隔を広げ、次にボルト３１を緩めてリブピース３６の上方から引き抜くと共に、リブピース３６を下方に引き抜く。
そして、新しいリブピース３６と交換して再び取付ければ良く、リブピース３６の交換後苗載台１０を元の位置に戻すだけで良く、エプロンを取り外すものとは異なり、苗の掻取量の再調節は必要ない。
【００１６】
従って、リブ部分の交換に当たり、従来はリブ全体を新しいものと交換していたため、これの交換作業にかなりの時間と費用とを必要としていたが、本発明によれば、リブ２６下端部のリブピース３６のみを交換するだけで良く、しかも、リブピース３６を交換する際に、苗の掻取量を再度調節する必要もないので、その操作は迅速・容易となり、メンテナンスが簡単になると共に、コスト的にも有利となるものである。
しかも、リブ２６を一対の半割リブ２７ａ，２７ｂの突き合わせで構成したものでは、リブ２６の下端部分がエプロン１５との摺動による摩擦で開き易くなるにも係わらず、下端の両嵌合突片３４ａ，３４ｂにリブピース３６を外嵌したものでは、これを押さえてしっかりと嵌合する役目を果たすものである。
【００１７】
【発明の効果】
本発明は、前記の如く、左右のマット苗の間を仕切るリブ２６を縦方向に複数設けた苗載台１０と、該苗載台１０の下端側に複数の掻取口２２を有したエプロン１５を設け、前記苗載台１０をエプロン１５に対して左右往復動させながら、前記掻取口２２から苗植付爪２０・・でマット苗を掻取って圃場に植付ける移植機において、前記エプロン１５に対向するリブ２６の下端部に、リブ本体２７に連続するリブピース３６を着脱可能に装着したことにより、移植機の長時間の使用によってリブ２６の下端部３６が磨耗して交換が必要となった場合には、上記リブピース３６のみを交換すれば良く、その交換操作は迅速・容易となり、メンテナンスも簡単になると共に、コスト的にも有利となるものである。
【００１８】
また、苗載台のリブ２６を、その上壁部において左右に分割した半割リブ２７ａ，２７ｂの突き合わせで構成すると共に、エプロン１５に対向する左右の半割リブ２７ａ，２７ｂの下端部を突き合わせた状態で、両者をリブピース１５で結合するので、半割リブ２７ａ，２７ｂの下端部分が左右方向への摺動摩擦で開き易くなるにも係わらず、これを押さえて両者をしっかり嵌合する役目を果たす等有用な効果を奏するものである。

DETAILED DESCRIPTION OF THE INVENTION
An example of an embodiment of the present invention will be described below with reference to the drawings implemented in a riding rice transplanter. FIG. 1 is an overall side view of a passenger rice transplanter, and FIG. 2 is a plan view of the same. As in a normal rice transplanter, 1 is provided with a pair of wheels 2, 2, 3, and 3 at the front and rear, and is shaken up and down at the rear. A traveling machine body equipped with a rice transplanter 4 via a moving parallel link, the front part of the traveling machine body 1 is arranged with an engine 5, a preliminary seedling stage 6, a handle 7 for driving operation, and the like. Is provided with a driver's seat 8, and the rice planting device 4 provided at the rear is provided with a planting frame 9, a seedling table 10, a seedling planting device 11,. .

Furthermore, 14 is an extended seedling mounting base that is extended and attached to the upper rear end side of the seedling mounting base 10, 15 is an apron provided on the lower end side of the seedling mounting base 10, and 16 is clearly shown in FIG. An apron guard that guards the left and right protrusions of the apron 15, 22 is a scraping port provided in the apron 15, 18 is a rubber belt that feeds the mat seedlings on the seedling mounting table 10 in the front vertical direction, and 19 is a certain scratch. A planter guard 21 for guarding the trajectories of a plurality of seedling planting claws 20... Rotating while drawing a trajectory, 21 is a drawing marker.
[0008]
That is, in the rice transplanter of the present invention provided with the above-described devices, the mat seedlings for one row are placed on each unit seedling placing surface 23. At the same time as reciprocating left and right with respect to the apron 15, the mat seedlings are scraped one by one from the scraping opening 22 of the apron 15 by each seedling planting claw 20, and are planted on the rice field. It is.
And although illustration was abbreviate | omitted, the apron support plate was constructed in the attachment seat provided in the upper surface of the case which supports each seedling planting nail | claw 20, ..., and the apron 15 was provided so that sliding up and down was possible with respect to this apron support plate The seedling stage 10 is supported by the apron 15 so as to be slidable in the left-right direction via the slide piece.
Therefore, the adjustment of the amount of scraping for one strain (unit stock) is not the vertical movement of the conventional apron 15 alone, but the apron 15 and the seedling stage 10 with respect to the scraping locus of the seedling planting claw 20. It is designed to move up and down integrally.
[0009]
Next, FIG. 3 is a side view of the seedling stage, FIG. 4 is an enlarged side view of the main part of FIG. 3, and 24 is provided only on the unit seedling surface 23 of the left and right ends of the seedling stage 10. Reference numeral 25 denotes a seedling feed stopper for adjusting the number of planting strips, and reference numeral 25 denotes a seedling holder, which has a hook-like seedling having elasticity so that the mat seedling does not float due to vibration of the traveling machine body 1 or the like. A plurality of pressers 17 are attached to each unit seedling placement surface 23 from the rear to the vicinity of the front seedling scraping portion.
Reference numeral 26 denotes a rib for partitioning the seedling mounting table 10 in the vertical direction for each strip. A rib piece 36 continuous to the rib body 27 is detachably attached to a lower end portion of the rib 26 facing the apron 15. The details will be described with reference to FIG.
[0010]
FIG. 5 is an explanatory perspective view showing the configuration of the lower end side of the rib, and 28 is a pair of seedling mounting plates provided with one half rib 27a and the other half rib 27b on the left and right, A plurality of engaging projections 29... And engaging receiving portions 30 that engage with the protrusions 29 are formed on the upper wall side of the half ribs 27 a and 27 b.
Further, the pair of half-split ribs 27a and 27b has a pair of left and right symmetrical fitting protrusions in which half portions 33 each holding a bolt 31 and a nut 32 are hollowed out at the lower ends thereof. 34a and 34b are provided integrally.
Further, the seedling mounting frames 10a and 10b at both ends of the seedling mounting table 10 are provided with only one half of the half ribs 27a and fitting protrusions 34a (or 27b and 34b), respectively.
Then, the seedling mounting plates 28 are arranged in parallel in the left-right direction, the seedling mounting frames 10a and 10b are arranged at both ends thereof, and the engaging protrusions 29 formed on one adjacent half rib 27a and the other A rib main body 27 is formed by engaging with an engagement receiving portion 30 formed on the half-split rib 27b, and the seedling mounting plates 28a and the seedling mounting frames 10a and 10b are connected to each other. 10 is configured.
[0011]
On the other hand, the rib piece 36 is formed of a box-shaped integral body made of a synthetic resin material or the like provided with a hole portion 36a to be fitted in a state in which the pair of fitting protrusions 34a and 34b are abutted with each other. A hole 36c is formed in the mounting surface 36b so that the bolt 31 can be inserted therethrough. When the rib piece 36 is fitted on both the fitting protrusions 34a and 34b and attached, both the fittings are abutted in advance. The nuts 32 are placed in the spaces 33 of the mating pieces 34a and 34b, and after the rib pieces 36 are fitted, the bolts 31 are inserted and tightened from the upper holes 36c to fix them.
[0012]
Therefore, in the present invention, by combining a plurality of seedling stage plates 28... Which are common parts, various seedling stages 10 having different numbers of stripes can be easily configured at low cost. The seedling mounting plate 28... Is connected to the engagement connecting portions 37... By the plurality of engaging projections 29... On the upper wall portion of the rib body 26 and the engagement receiving portions 30. The rib pieces 36 at the lower end of the main body 27 are connected at a plurality of locations.
In this case, the number of parts constituting the seedling mounting base 10 can be reduced, and since the connecting portion is not formed on the seedling mounting surface 23, the mat seedling and the connecting portion can be prevented from being caught.
Reference numeral 38 denotes a cover portion formed so as to cover the top of the half rib 27a on the other side at the top of the half rib 27b on one side.
[0013]
The transplanting machine according to the present invention has the above-described configuration. When a seedling is placed on the seedling placing table 10 and planting is started at the time of planting the seedling by the rice planting device 4, the seedling placing table 10 is started. Reciprocates in the left-right direction with respect to the apron 15. In the meantime, the mat seedlings are scraped for each strain by the seedling planting claws 20..
At this time, when the seedling planting claws sequentially scrape the seedlings in one horizontal row and scrape off the seedlings at the end, the rubber belt 18... Then, the mat seedling is fed out to the apron 15 side, and the same action is repeated by the seedling planting claws 20.
When it is desired to change the scraping amount of the seedlings for one strain, in the case of the present invention, the seedling mounting table 10 and the apron 15 are attached to the seedling planting claws 20 by a separate operation lever (not shown). This is done by moving up and down integrally with the scraping locus.
[0014]
In this way, when performing seedling planting work, the rib pieces 36 attached to each rib body 27... Can be separated from adjacent strips by making the gap between the apron 15 as small as possible. The sliding resistance between the apron 15 and the lower end of the mat seedling prevents the lower end portion of the mat seedling from being sandwiched between the rib and the apron 15 and being damaged.
However, while the transplanter is used for a long time, the floor soil of the mat seedling that has been peeled off due to the friction between the mat seedling and the apron 15 is sandwiched between the lower end of the rib piece 36 of the rib 26 and the apron 15. As a result, the rib piece 36 is gradually worn and the gap is enlarged.
In such a case, it is necessary to replace the rib piece 36 with a new one.
[0015]
That is, when replacing the rib piece 36, the seedling stage 10 is slightly lifted from the apron 15 to widen the gap between the lower end of the rib piece 36 and the apron 15, and then the bolt 31 is loosened and pulled out from above the rib piece 36. Pull 36 down.
Then, it is only necessary to replace the rib piece 36 and reattach it, and after the rib piece 36 is replaced, it is only necessary to return the seedling mounting table 10 to its original position. Is not necessary.
[0016]
Accordingly, when replacing the rib portion, since the entire rib has been replaced with a new one in the prior art, a considerable amount of time and cost was required for the replacement operation. According to the present invention, the rib piece at the lower end portion of the rib 26 is used. It is only necessary to replace 36, and when the rib piece 36 is replaced, it is not necessary to adjust the scraping amount of the seedling again. It is also advantageous.
In addition, in the case where the rib 26 is configured by a pair of halved ribs 27a and 27b, the lower end portion of the rib 26 is easily opened due to friction caused by sliding with the apron 15, but both fitting protrusions on the lower end are formed. In the case where the rib piece 36 is externally fitted to the pieces 34a, 34b, the rib piece 36 is pressed and functions to be firmly fitted.
[0017]
【The invention's effect】
In the present invention, as described above, the apron having the seedling mounting base 10 provided with a plurality of ribs 26 for separating the left and right mat seedlings in the vertical direction and the plurality of scraping ports 22 on the lower end side of the seedling mounting base 10 is provided. In the transplanting machine for scraping the mat seedlings with the seedling planting claws 20... And transplanting them in the field while reciprocating the seedling mounting table 10 left and right with respect to the apron 15, Since the rib piece 36 continuous to the rib main body 27 is detachably attached to the lower end portion of the rib 26 facing the apron 15, the lower end portion 36 of the rib 26 is worn away and needs to be replaced by using the transplanter for a long time. In this case, only the rib piece 36 needs to be replaced, and the replacement operation is quick and easy, the maintenance is simplified, and the cost is advantageous.
[0018]
Further, the rib 26 of the seedling stand is configured by butting the half ribs 27a and 27b divided into the left and right at the upper wall portion, and the bottom ends of the left and right half ribs 27a and 27b facing the apron 15 are butted. In this state, the rib pieces 15 are coupled to each other, so that the lower end portions of the half ribs 27a and 27b are easily opened by sliding friction in the left-right direction, but the role of pressing and holding the ribs is firmly engaged. It has a useful effect such as fulfilling.
