Description

【０００１】
【発明の属する技術分野】
この発明は、野菜等の苗を畑圃場に形成した畝に植付ける苗植機の技術分野に属する。
【０００２】
【従来の技術】
従来、実開平３−１１７４０８号公報に開示されるように、畝を跨いで走行する左右一対の前輪と左右一対の後輪を設けた車体の後部に歩行操縦用の操縦ハンドルを設け、機体側面視で前記後輪から操縦ハンドルにかけての前後間に、上下動して圃場に苗を植付ける苗植付装置と、該苗植付装置の上から苗を供給する苗供給装置を設けた苗植機がある。
【０００３】
【発明が解決しようとする課題】
上記従来の苗植機では、作業者が機体の前進走行に追従して歩行しながら苗供給装置に苗を補給しなければならないので、作業が容易ではなかった。また、広幅の畝に対して植付作業を行う場合は、作業者が歩行する個所となる畝側方の谷部と、植付作業を行う畝の上方に位置する苗供給装置まで遠くなり、苗供給装置への苗補給作業が容易に行えなかった。
【０００４】
そこで、機体に座席を設けてその座席に座って苗供給装置に苗を補給することが考えられる。畑圃場での苗植機において、そのような座席を設けたものは、例えば、実開昭６０−８７５１１号公報に開示されるように、機体側面視で前輪と後輪との前後間に苗植付装置を配置した構成の苗植機において、機体側面視で前輪と後輪との前後間であって苗植付装置の後方近傍に作業者用座席を配置したものがある。しかしながら、機体側面視で後輪から機体後部の操縦ハンドルにかけての前後間に苗植付装置と、該苗植付装置の上から苗を供給する苗供給装置を設けた歩行操縦タイプの構成とした苗植機においては、前記の苗植機とは苗植付装置の位置が異なり、もともと前記のように作業者が乗車する構成を意図していない構成であるため、このような構成の苗植機に、苗供給装置への苗補給作業を行う座席を設けるには、少なからずの工夫を要する。前記の苗植機のように単純に苗供給装置の後側に配置したのでは、苗供給装置の手前に操縦ハンドルが位置することになって苗供給装置への苗補給作業が容易に行えず、また、機体の前後長が長くなって、機体の操縦性が悪くなるのである。
【０００５】
そこで、本発明は、機体側面視で後輪から機体後部の操縦ハンドルにかけての前後間に苗植付装置と苗供給装置を設けた歩行操縦タイプの構成とした苗植機において、苗補給作業用の座席を設けて苗補給作業の容易化を図るとともに、機体の前後長が長くならないようして機体の操縦性をできるだけ低下させないようにすることを課題とする。
【０００６】

【００１１】
【作用及び発明の効果】
請求項１記載の発明の苗植機は、左右の走行部１，１，１４，１４が畝を跨いで走行し、苗供給装置４が苗を苗植付装置５に供給し、苗植付装置５は上下動して圃場に苗を植付ける。苗供給装置４への苗の補給作業は、車体３に設けた作業者着座部Ｓの座席６に作業者が座って行える。座席６は、操縦ハンドル２の後端部より前側且つ左右外側で苗供給装置４の後側近傍にを配置されるので、苗供給装置４への苗の補給作業が容易に行え、しかも、座席６を設けた構成であるが機体の前後長が長くならず、機体操縦も容易に行える。更に、作業者着座部Ｓを車体３に対して左右位置変更可能に設けたので、作業時には苗供給装置４への苗の補給作業が行い易い位置に座席６の左右位置を調節でき、また、非作業時には作業者着座部Ｓを機体内側に移動して機体幅を狭く、機体の運搬、移動、格納をし易くできる。
【００１２】
請求項２、３及び５記載の発明の苗植機は、作業走行中、作業者着座部Ｓの座席６に着座した作業者の体重は支持輪７により畝側方の谷部の地面に支持されるので、機体の前後バランスの崩れが生じにくく、苗の植付性能の低下も生じ難い。
【００１３】
更に、請求項２記載の発明の苗植機は、畝側方の谷部を通過する支持輪７より左右方向機体内側寄りに座席６を配置可能なので、機体左右内側に寄って作業者は着座でき、苗供給装置４への苗の補給作業が更に容易に行える。
【００１４】
また、請求項３記載の発明の苗植機は、支持輪７を座席６に対して左右位置変更可能なので、苗供給装置４への苗の補給作業が容易に行えるように座席６を苗供給装置４に対して配置した状態を変更せずに、幅の異なる畝でも支持輪７を畝側方の谷部を通過するよう位置調節が可能となる。
【００１５】
請求項４記載の発明の苗植機は、座席６に着座する作業者が足を載せる足載せ部８が座席６の前側下方で座席６とともに左右移動する部材に設けているので、作業者は座席６に着座して楽な体勢をとることができ苗供給装置４への苗の補給作業が容易に行え、また、座席６の左右位置を調節しても、座席６とともに足載せ部８が左右移動するので、座席６に対する足載せ部８の位置関係が変わらず、足載せ部８への足載せが楽に行え、作業性が低下しない。
【００１６】
請求項５記載の発明の苗植機は、作業者が座席６に着座すると支持輪７が接地し、作業者が座席６から外れれば支持輪７が非接地状態となるよう上昇するので、機体旋回が容易に行え、操縦性が大きく悪くなることもない。
【００１７】
【発明の実施の形態】
この発明の一実施例を図面に基づいて説明する。
図に示す苗植機は、畝を跨いで走行する左右一対の前輪１４，１４と左右一対の後輪１，１からなる走行部を設けた車体３の後部に歩行操縦用の操縦ハンドル２を設け、機体側面視で前記走行部の後側接地部（後輪）１，１から操縦ハンドル２にかけての前後間に、上下動して圃場に苗を植付ける苗植付装置５と、該苗植付装置５の上から苗を供給する苗供給装置４を設けた構成のものである。
【００１８】
本例では、上記車輪１４，１４，１，１のうち左右一対の前輪１４，１４を遊転車輪とし、左右一対の後輪１，１を動力が伝達されて駆動回転する駆動車輪としている。なお、上記車輪１４，１４，１，１によるホイールタイプの走行部に替えて、クローラタイプの走行部を採用することもできる。この場合、上下動して圃場に苗を植付ける苗植付装置５と、該苗植付装置５の上から苗を供給する苗供給装置４は、機体側面視でクローラの接地部後端部から操縦ハンドル２にかけての前後間に配置される。また、上記左右の走行部１４，１４，１，１は、車体３に対して左右位置変更調節可能に設けていて、畝幅が異なる場合にも適宜対応して走行することができるようになっている。走行部１４，１４，１，１の車体３に対する左右位置変更調節機構は、走行部１４，１４，１，１の車体３に対する支持部を左右伸縮構成にする等の構成で可能となる。
【００１９】
車体３の各部具体構成について以下説明する。車体３は、その前部にエンジン１３を搭載し、前部左右両側には前輪１４，１４を伸縮可能の前輪アーム１５で支持し、左右両側のアクスルハウジング１６，１６の周りに後部が上下動可能の伝動ケース１７，１７の後部側面から突出する車軸１８に駆動車輪１，１を装着し、エンジン１３の後側に配置したミッションケース１９の後部から後方にのびるフレーム１０を突出させて、このフレーム１０の後上がり傾斜でのびる後部の上端部に歩行操縦用の操縦ハンドル２を取付けている。操縦ハンドル２の後端部は、機体後方側に立つ操縦者が手で握るグリップ部１１となっており、そのグリップ部は図に示すように左右一対設けた構成としても、操縦ハンドルの左右各後端部を互いに連結して平面視ループ状のハンドルに構成してもよい。この場合、操縦ハンドルの左右各後端部を互いに連結する部分をグリップ部に構成する。
【００２０】
また、車体３の前記ミッションケース１９の後側には、油圧等により駆動される車輪昇降用シリンダ２０を有し、該シリンダ２０から後方に突出し或はシリンダ２内に引込み動作するピストンの先端部に左右横方向にのびるアーム２１の中央部を連結している。このアーム２１の左右両端部と駆動車輪１，１を取付けた前記伝動ケース１７，１７の基部に一体のアーム２２との間を、右側では連動ロッド２３で連結し、左側では油圧等によって伸縮動作可能なローリング動作用シリンダ２４を介在させて連結する。このように構成により、車輪昇降用シリンダ２０を伸縮動作させると、左右の駆動車輪１，１が上下動し、車体３が上下動することになる。また、ローリング動作用シリンダ２４を伸縮動作させるとローリング動作用シリンダ２４を設けた側の駆動車輪１が昇降し、車体３が左右に傾動することになる。車輪昇降用シリンダ２０は左右の駆動車輪１，１の間に配置されて畝上面に接地する接地センサ２５によって車体３の畝上面に対する高さが検出され、この検出高さが設定高さとなるように車輪昇降用シリンダ２０が動作するように構成している。ローリング動作用シリンダ２４の伸縮動作は、操縦ハンドル２付近に設けた操作具によって操縦者が適宜動作可能に構成している。
【００２１】
駆動車輪１，１及び前輪１４，１４は、前述のようにアクスルハウジング１６，１６及び前輪アーム１５，１５の伸縮によって左右位置調節されてトレッド変更可能に構成される。これにより、苗を植付けする畝Ａの左右幅が異なっても、それに対応して左右車輪の左右位置を調節し、該左右の車輪を畝Ａの左右両側の谷部Ｂを適宜走行させられる。
【００２２】
苗植付装置５，５は、本例では、同時に２条植え付けられるよう左右に並べて２体設け、且つ、二体の苗植付装置５，５は左右車輪間の中央位置から左右一方側に偏らせて配置したものとしている。これにより広幅の畝Ａを往復作業走行して４条植え付けることができる。各苗植付装置５は苗を上方から投入されるようになっていて下部が前後に開閉する一対のくちばし状の苗植付具２７となっている。苗植付装置５，５は、各苗植付装置５の上方に設けた苗供給装置４，４の苗供給カップ２８から落下供給される苗を受けて下降し、畝Ａにくちばし状の苗植付具２７の下部が突き刺して前後に開き、植付穴を形成するとともに苗をその植付穴に放出して植付る。前記ミッションケース１９の後部には植付伝動ケース２９が連結されていて、この植付伝動ケース２９内の伝動機構を経由して苗植付装置５，５と苗供給装置４、４等が駆動される。前後一対の駆動回転するアーム３０，３０によって、後部が前後揺動自在の支持アーム３２，３２に回動自在に支持される前後の昇降アーム３１，３１が上下動されるように構成され、この昇降アーム３１，３１の各先端部を苗植付具２７の前後の支持軸３３，３３に回動自在に取付けている。昇降アーム３１，３１が上下動されることによって苗植付具２７が植付軌跡線Ｔに沿って上下動され、また、昇降アーム３１，３１に連動する苗植付具２７の開閉機構が作動して、上端位置から下端位置までの下降するときははくちばし状の苗植付具２７が閉じた状態となり、下端位置で前後に開き、そして、前後に開いた状態で上昇し、上端位置で再び閉じるように動作する。植付後の苗は、その左右側方の土が左右の鎮圧輪２６，２６で鎮圧されて覆土される。
【００２３】
苗供給装置４、４は、左右の苗植付具２７，２７の各上方に配置される。苗供給装置４，４は、それぞれ、中心部を支持ベース３４に設けられた軸心上下方向の回転軸３５によって回転駆動される円盤状部材の外周に沿ってカップ状の苗供給カップ２８・・・を複数一定間隔で配置した構成である。作業者は、苗供給カップ２８・・・の上方から苗を投入して苗を補給することになる。各苗供給カップ２８の底部には開閉自在の底蓋３６が設けられ、前記軌跡Ｔの上端位置に苗植付具２７が位置するとき、その上方に繰り出された苗供給カップ２８の底蓋３６が開き、それ以外の場所では底蓋３６が閉じるように設けている。苗植付具２７が上下動するごとに苗供給装置４、４が回転駆動されて苗を収容した苗供給カップ２８・・・が苗植付具２７の上方に一つづつ繰り出されるように動作して、苗植付具２７に苗を供給するようになっている。苗供給装置４，４への伝動は、前記植付伝動ケース２９内の伝動機構を経由して伝動され、苗植付装置５，５とタイミングを合わせて連動する。左右の苗供給装置４，４の各支持ベース３４，３４は、前記植付伝動ケース２９の上部と前記フレーム１０の後部とに前後端部を取付けた中央支持フレーム３７と、該中央支持フレーム３７から左右にのびる側部支持フレーム３８とで支持する構成としている。苗供給装置４，４の前側の機体上部に、支持フレーム３９で支持される予備苗載台４０を設け、該予備苗載台４０に苗を収容した苗箱を載せられるようになっている。
【００２４】
上記のように構成した苗植機において、前記苗供給装置４に苗を補給する作業者が座る座席６を備えた作業者着座部Ｓを設けた構成としている。
【００２５】
図に示した本例の構成は、以下のようになっている。座席６は、操縦ハンドル２の後端部より前側且つ側方で苗供給装置４，４の後側近傍で左右外側寄りに設けられている。この座席６に作業者が座れば、苗供給装置４，４と操縦ハンドル２との近くに位置するため、苗供給装置４，４の苗供給カップ２８・・・への苗の補給作業が容易に行え、また、操縦ハンドル２やその近傍に配置された機体操縦用の操作具の操作も容易に行うことができる。更に、この座席６は機体側部に位置するため、作業者Ｍは、畝Ａを踏むことなく畝側方の谷部Ｂから容易に乗り降りできる。支持輪７はこの座席６の下側に設けられる。又、足載せ部としてのステップ８はこの座席６の前側下方に設けられる。
【００２６】
座席６を車体３に取付ける座席支持フレーム１２は、前記フレーム１０の後部に取付けられるブラケット４１の後端部に左右両側方にのびるように取付けている。座席支持フレーム１２は、ブラケット４１に固定の支持パイプ４２と、この支持パイプ４２の左右両外側部に摺動自在に挿入される伸縮パイプ４３とで構成し、この伸縮パイプ４３の先端部に上下方向の軸穴を形成したボス４４を固着し、これに背面視Ｌ字状に屈曲する支持杆４５の上下にのびる部位を摺動自在に挿入し、ボス４４の上側に突出する支持杆４５の上端部に座席６を取り付けている。また、座席６とボス４４の上端部の間にバネ９を介在させている。支持杆４５の下部の左右外側方にのびるアーム部４６には左右位置調節自在にブラケット４７を取付け、それに支持輪７を回転自在に取付けている。ステップ８は、この支持杆４５から前側に一体的に取付けられる。
【００２７】
上記のように構成した苗植機において、前記苗供給装置４に苗を補給する作業者が座る座席６を前記操縦ハンドル２の後端部より前側且つ左右外側で前記苗供給装置４の後側近傍に配置した作業者着座部Ｓを前記車体３に設けた構成としている。
【００２８】
よって、この苗植機は、左右の走行部１，１，１４，１４が畝を跨いで走行し、苗供給装置４が苗を苗植付装置５に供給し、苗植付装置５は上下動して圃場に苗を植付ける。苗供給装置４への苗の補給作業は、車体３に設けた作業者着座部Ｓの座席６に作業者が座って行える。座席６は、操縦ハンドル２の後端部より前側且つ左右外側で苗供給装置４の後側近傍にを配置されるので、苗供給装置４への苗の補給作業が容易に行え、しかも、座席６を設けた構成であるが機体の前後長が長くならず、機体操縦も容易に行える。
【００２９】
また、作業者着座部Ｓを車体３に対して左右位置変更可能に設けたので、作業時には苗供給装置４への苗の補給作業が行い易い位置に座席６の左右位置を調節でき、また、非作業時には作業者着座部Ｓを機体内側に移動して機体幅を狭く、機体の運搬、移動、格納をし易くできる。
【００３０】
前記作業者着座部Ｓに、前記座席６に着座した作業者の体重を地面に支持させる支持輪７を、前記走行部１，１，１４，１４の後方に配置可能にして設けている。よって、作業走行中、作業者着座部Ｓの座席６に着座した作業者の体重は支持輪７により畝側方の谷部の地面に支持されるので、機体の前後バランスの崩れが生じにくく、苗の植付性能の低下も生じ難い。
【００３１】
前記支持輪７より左右方向機体内側寄りに前記座席６を配置可能に設けている。よって、畝側方の谷部を通過する支持輪７より左右方向機体内側寄りに座席６を配置可能なので、機体左右内側に寄って作業者は着座でき、苗供給装置４への苗の補給作業が更に容易に行える。
【００３２】
前記支持輪７を前記座席６に対して左右位置変更可能に設けている。よって、苗供給装置４への苗の補給作業が容易に行えるように座席６を苗供給装置４に対して配置した状態を変更せずに、幅の異なる畝でも支持輪７を畝側方の谷部を通過するよう位置調節が可能となる。
【００３３】
前記作業者着座部Ｓに、前記座席６に着座する作業者が足を載せる足載せ部８を、前記座席６の前側下方で前記座席６とともに左右移動する部材に設けている。よって、座席６に着座する作業者が足を載せる足載せ部８が座席６の前側下方で座席６とともに左右移動する部材に設けているので、作業者は座席６に着座して楽な体勢をとることができ苗供給装置４への苗の補給作業が容易に行え、また、座席６の左右位置を調節しても、座席６とともに足載せ部８が左右移動するので、座席６に対する足載せ部８の位置関係が変わらず、足載せ部８への足載せが楽に行え、作業性が低下しない。
【００３４】
前記作業者着座部Ｓを車体３に取付けるフレーム４２，４３に対し前記座席６と前記支持輪７とが一体的に上下動自在に設けるとともに、前記フレーム４２，４３側と前記座席６及び支持輪７側の間に、前記座席６及び支持輪７を上方に付勢する付勢体９を設け、作業者が座席６に着座していないときは支持輪７が非接地状態となるよう該付勢体９によって座席６及び支持輪７が上昇し、作業者が座席６に着座しているときは作業者の体重により支持輪７が接地状態となるよう座席６及び支持輪７が下降する構成としている。よって、作業者が座席６に着座すると支持輪７が接地し、作業者が座席６から外れれば支持輪７が非接地状態となるよう上昇するので、機体旋回が容易に行え、操縦性が大きく悪くなることもない。
【００３５】
前記作業者着座部Ｓを車体３に取付けるフレーム４２，４３を左右方向にのびる部材で構成し、該フレーム４２，４３を、後端部に前記操縦ハンドル２を取付けた前後にのびるハンドルフレーム１０に取付けている。よって、作業者着座部Ｓの車体３への取付けが簡易なフレーム構成で可能となり、機体の重量アップやコストアップをできるだけ少なくできる。

BACKGROUND OF THE INVENTION
This invention belongs to the technical field of a seedling planting machine for planting seedlings such as vegetables on a cocoon formed in a field field.
[0002]
[Prior art]
Conventionally, as disclosed in Japanese Utility Model Laid-Open No. 3-117408, a steering handle for walking maneuvering is provided at the rear of a vehicle body provided with a pair of left and right front wheels and a pair of left and right rear wheels traveling across a saddle, Seedling planting apparatus provided with a seedling planting device for moving seedlings in the field by moving up and down between the rear wheel and the steering handle, and a seedling supply device for feeding seedlings from above the seedling planting device There is a machine.
[0003]
[Problems to be solved by the invention]
In the conventional seedling planting machine described above, the worker has to replenish seedlings to the seedling supply device while walking following the forward traveling of the machine body, so the operation is not easy. In addition, when performing planting work on a wide cocoon, it is far from the trough side trough where the worker walks and the seedling supply device located above the cocoon performing the planting work, The seedling supply operation to the seedling supply device could not be easily performed.
[0004]
Therefore, it is conceivable to provide a seat on the machine body and sit on the seat to supply seedlings to the seedling supply device. In a seedling planting machine in a field field, for example, as disclosed in Japanese Utility Model Laid-Open No. 60-87511, a seedling planting machine between a front wheel and a rear wheel in a side view of the body is disclosed. In a seedling planting machine having a configuration in which a planting device is arranged, there is one in which a worker's seat is arranged in the vicinity of the rear of the seedling planting device between the front and rear wheels in a side view of the body. However, it is a walking maneuvering type configuration in which a seedling planting device and a seedling feeding device for supplying seedlings from above the seedling planting device are provided between the rear wheel and the steering handle at the rear of the aircraft body in a side view. In the seedling planting machine, the position of the seedling planting device is different from that of the seedling planting machine, and it is originally a configuration that is not intended for the operator to get on as described above. In order to provide the machine with a seat for performing seedling replenishment work to the seedling supply device, it requires a certain amount of ingenuity. If the seedling feeder is simply arranged behind the seedling feeder, the steering handle is positioned in front of the seedling feeder, and the seedling replenishment operation to the seedling feeder cannot be easily performed. In addition, the longitudinal length of the aircraft becomes longer, and the maneuverability of the aircraft deteriorates.
[0005]
Therefore, the present invention provides a seedling planting machine having a walking maneuvering type configuration in which a seedling planting device and a seedling feeding device are provided between the rear wheel and the steering handle at the rear of the aircraft in a side view of the aircraft. An object of the present invention is to make the seedling replenishing work easier by providing a seat and to prevent the front and rear length of the airframe from becoming long so that the maneuverability of the airframe is not lowered as much as possible.
[0006]
