Description

【０００１】
【発明の属する技術分野】
本発明は、種ニンニク等の球根や種芋等の芋類などの植付け対象物を所定の姿勢で植付ける球根類植付装置に関する。
【０００２】
【従来の技術】
種ニンニク等の球根や種芋等の芋類などを圃場に植付けするために、自走機等に搭載した球根類植付装置が知られている。従来の球根類植付装置は、半自動野菜移植機に搭載されたクチバシ方式のものがあるが、この植付装置は、植付け対象物の上下の位置が定まらないので、例えば、サトイモは発芽した種芋をその発芽部分を上にして植付けないと出芽時期がまちまちになって生育がばらつくという問題を生じ、また、ニンニクについては、その左右の向きを定めて植付けないと葉の向きを管理できないという問題があった。
この問題を解決するために、特許文献１に記載のように、種ニンニクの球根をテープ上に１列に並べて保持したニンニクテープを作り、これを植付装置によって植付けすることにより、テープ上に保持した姿勢により植付けすることができる。

【０００３】
【発明が解決しようとする課題】
しかしながら、ニンニクテープ方式の上記の植付装置は、植付けするべき全ての種ニンニクについて事前にニンニクテープを作る必要があるので、圃場における植付作業に加え、その準備工程の作業のために大きな負荷を強いるものであった。
【０００４】
本発明が解決しようとする課題は、植付け作業前に特段の準備工程を要することなく、植付け対象物である球根や芋類などを所定の姿勢で圃場に植付けられる球根類植付装置を提供することにある。
【０００５】
【課題を解決するための手段】
上記課題を解決するために、請求項１に係る発明は、球根や種芋などの植付け対象物を保持する保持手段と、該保持手段から植付け対象物を取出して圃場に植付ける植付手段と、前記保持手段を該保持手段に植付け対象物を装填する位置から前記植付手段が前記保持手段から植付け対象物を取出す位置に搬送する搬送手段を備え、前記保持手段は、装填された植付け対象物の外周面に沿って弾性変形しながら接触する保持部材を備えて、該保持部材により装填された植付け対象物を姿勢変化しないように保持する構成としたことを特徴とする。
【０００６】
上記構成の球根類植付装置は、球根や種芋などの植付け対象物が保持手段に装填されると、保持手段の保持部材が、装填された植付け対象物の外周面に沿って弾性変形しながら接触して、装填された植付け対象物を姿勢変化しないように保持する。保持手段に装填され保持された植付け対象物は搬送手段によって搬送され、設定位置に搬送されてきた植付け対象物は、植付手段によって保持手段から取出されて圃場に植付けられる。
【０００７】
請求項２に係る発明は、請求項１記載の球根類植付装置において、前記保持手段の保持部材は、植付け対象物の装填個所に毛先が向うように植立された弾性変形可能な多数の立毛体により構成したことを特徴とする。
【０００８】
このように構成した球根類植付装置は、多数の立毛体の毛先側が、装填された植付け対象物の外周面に沿って弾性変形しながら接触して、装填された植付け対象物を姿勢変化しないように保持する。
【０００９】
【発明の効果】
本発明は以下の効果を奏する。
請求項１記載の発明は、上記のように構成したものなので、植付作業前に特段の準備工程を要することなく、圃場において、種ニンニク等の球根や種芋等の芋類などの植付け対象物を保持手段に装填するだけで所定の姿勢で圃場に植付けすることができる。
【００１０】
請求項２記載の発明は、前記保持部材を、植付け対象物の装填個所に毛先が向うように植立された弾性変形可能な多数の立毛体により構成したので、簡易な構成であるにもかかわらず、植付け対象物を姿勢変化しないように適確に保持でき、且つ、植付手段が保持手段から植付け対象物を適確に取出せるものとなる。
【００１１】
【発明の実施の形態】
上記技術思想に基づき具体的に構成された実施の形態について以下に図面を参照しつつ説明する。
【００１２】
球根類植付装置の正面図を図１に、そのＡ−Ａ線断面図を図２に、そのＢ−Ｂ線断面図を図３に示す。図１〜図３において、球根類植付装置1は、球根や種芋などの植付け対象物Ｗを保持する保持手段（ホルダ５）と、該保持手段５から植付け対象物Ｗを取出して圃場に植付ける植付手段（植込み体７）と、前記保持手段５を該保持手段５に植付け対象物Ｗを装填する位置から前記植付手段７が前記保持手段５から植付け対象物Ｗを取出す位置に搬送する搬送手段（チェーン３）を備え、前記保持手段５は、装填された植付け対象物Ｗの外周面に沿って弾性変形しながら接触する保持部材２２を備えて、該保持部材５により装填された植付け対象物Ｗを姿勢変化しないように保持する構成としたものである。
【００１３】
従って、このように構成した球根類植付装置１は、球根や種芋などの植付け対象物Ｗが保持手段５に装填されると、保持手段５の保持部材２２が、装填された植付け対象物Ｗの外周面に沿って弾性変形しながら接触して、装填された植付け対象物Ｗを姿勢変化しないように保持する。保持手段５に装填され保持された植付け対象物Ｗは搬送手段３によって搬送され、設定位置に搬送されてきた植付け対象物Ｗは、植付手段７によって保持手段５から取出されて圃場に植付けられる。このように、植付作業前に特段の準備工程を要することなく、圃場において、種ニンニク等の球根や種芋等の芋類などの植付け対象物を保持手段に装填するだけで所定の姿勢で圃場に植付けすることができ、能率的且つ適確に球根や芋類などを植付けることができるようになる。
【００１４】
また、保持手段５は、植付け対象物Ｗを装填する位置において、植付け対象物Ｗを上方から装填可能に構成し、植付手段７が植付け対象物Ｗを取出す位置において、植付け対象物Ｗを下方に取出し可能とし、また、このとき、植付手段７が保持手段５の植付け対象物Ｗの保持個所に上方から進入して下方に移動可能とする空間（隙間Ｇ）を形成する。植付手段７には、植付け対象物Ｗの一部に係合する係合部を設ける。これにより、植付け対象物Ｗは、保持手段５の上方から押し込まれて装填され保持され、また、植付手段７が、保持手段５の上方から移動してきて保持手段５内を下降し、このとき、保持手段５が保持する植付け対象物Ｗの上部に植付手段の係合部が係合して下方に押出し、植付け対象物Ｗを下方に取出す。取出された植付け対象物Ｗは、その上部が植付手段の係合部に係合して取出された姿勢のままで保持されて土中に持ち込まれ植付けられる。
【００１５】
保持手段５の保持部材２２には、スポンジのような発砲材料によって構成することができるが、図例のように、植付け対象物Ｗの装填個所に毛先が向うように植立された弾性変形可能な多数の立毛体により構成すると、簡易な構成であるにもかかわらず、植付け対象物を姿勢変化しないように適確に保持でき、且つ、植付手段が保持手段から植付け対象物を適確に取出せるものとなる。
【００１６】
搬送手段３は、上下に周回動する構成とし、その周回上部で植付け対象物Ｗを保持手段５に装填し、周回下部で植付手段７が保持手段５から植付け対象物Ｗを取出して圃場に植付ける構成とすることで、圃場面Ｓから高い位置で保持手段５に植付け対象物Ｗを装填できるので、人手により植付け対象物Ｗの装填作業を行う場合にその装填作業が楽な姿勢で能率良く行えるようになり、なお且つ、圃場面Ｓに近い位置で植付手段７が植付け対象物Ｗを保持手段５から取出せるので、保持手段５から取出した後、圃場の土中まで植付手段７が植付け対象物Ｗを持って行く行程が短くなって、そのぶんその行程での姿勢の乱れも生じにくくなり植付精度が向上する。また、植付手段７の動作範囲を小さくできて機体のコンパクト化も図れる。
【００１７】
植付手段７は、その先端部７ａに植付け対象物Ｗの一部に係合する係合部を設け、この植付手段７の先端部７ａが保持手段５が保持する植付け対象物Ｗの上方から植付け対象物Ｗの上部に係合して圃場の土中に至るまで下降するよう構成することで、植付手段７が保持手段５から植付け対象物Ｗを保持姿勢のままで取出して圃場に植付けるようになっている。
【００１８】
なお、保持手段５が、上記のように構成した搬送手段３に固定されて周回すると、保持手段５が、前記のように、植付け対象物Ｗを装填する位置において、植付け対象物Ｗを上方から装填可能に構成し、植付手段７が植付け対象物Ｗを取出す位置において、植付け対象物Ｗを下方に取出し可能に構成されている場合、保持手段５への装填時の植付け対象物Ｗの保持姿勢と、植付手段７による取出し時の植付け対象物Ｗの保持姿勢は上下反対となる。従って、保持手段５への装填時には、植付後に上になる側を下側にした姿勢で植付け対象物Ｗを保持手段５へ装填する。すると、植付手段７が植付け対象物Ｗを取出す位置に保持手段５が搬送されると、保持手段５は搬送手段３の上部に位置するときとは上下に反転し、その保持手段５に保持される植付け対象物Ｗは上下が適正な姿勢になり、この姿勢で植付手段７が植付け対象物Ｗを取出して圃場に植付ける。
【００１９】
また、この球根類植付装置1は、自走機に搭載可能に構成されることで、圃場を移動しながら連続的に植付作業が行える。
【００２０】
図例の構成を詳細に説明する。搬送手段としてのチェーン３は、略同高さに配置した一方が駆動回転し他方が従動回転する二つのスプロケット１１，１１と、その下方に略水平に配置した案内板１２とに掛け回されて駆動回転するように設けている。案内板１２は、圃場面Ｓに近接した下部位置でチェーン３を水平送りするガイドである。これにより、搬送手段は、二つのスプロケット１１，１１間の上部横移動部と、その右端から下方に続く下方移動部と、圃場面Ｓに近接する案内板１２下方の下部横移動部と、上部の横移動部に斜めに上昇する上方移動部とからなる略三角形状の周回軌跡を有する。ホルダ５は、後述のように、装填された植付け対象物Ｗの外周面に沿って弾性変形しながら接触する立毛体等からなる保持部材２２を備え、チェーン３のリンクに固定する。
【００２１】
植込み体７は、支枠１３から突出する駆動回転軸に取付けられて回転する駆動アーム１４の先端部に取付けた軸１４ａと、支枠１３の別の個所から突出する支持軸に取付けられて自由回動する回動アーム１５の先端部に取付けた軸に回動自在に取付けたもので、駆動アーム１４の駆動回転によって、植込み体７の先端部７ａは、縦長楕円状軌跡Ｔを描くように上下に周回動作する。そして、植込み体７の先端部７ａが、チェーン３の下部位置でホルダ５の植付け対象物Ｗの保持個所を上から下へ通過する位置関係に設定し、かつ、チェーン３による各ホルダ５の移送と同期して駆動アーム１４を動作させることにより、植込み体７の先端部７ａは、ホルダ５に保持された植付け対象物Ｗを保持された姿勢のままで上から下へ押し出し、植込み体７の動作の勢いによって、植付け対象物Ｗをその姿勢のままで先端部７ａが保持しながら圃場面Ｓまで持って行って土中に押し込み植付ける。
【００２２】
なお、植付手段７が保持手段５から植付け対象物Ｗを取出すとき搬送手段３が停止し、植付手段７が植付け対象物Ｗを取出した後に次の保持手段５が植付手段７による取出し位置に移動するよう搬送手段３が動作するよう搬送手段３を間欠的に駆動する構成とすると、植付手段７が保持手段５から植付け対象物Ｗを取出すのが一層良好に行えて、植付精度が向上する。
【００２３】
ホルダ５について詳細に説明すると、ホルダの拡大斜視図を図４に、ホルダに植付け対象物Ｗを装着した状態の拡大断面図を図５に示すように、ホルダ５は、隙間Ｇにより一側部を開放した略リング状（Ｃ字形状）のベース部材２１と、このベース部材２１からそのリング状形状の中心側に毛先が向かうように植立された弾性変形可能な多数の立毛体からなる保持部材２２を備える。ベース部材２１は、そのリング状形状の中心側を略直交する軸が搬送手段（チェーン３）の搬送方向に対し略直交する姿勢で、取付部材５ａを介して搬送手段（チェーン３）に取付ける。図４では手前側に形成したベース部材２１の開放部である隙間Ｇを、植付体７の先端部７ａ側が上から下に通過する。
【００２４】
このホルダ５に保持された植付け対象物Ｗは、植込み体７が、保持部材２２による保持力に抗してホルダ５内の植付け対象物Ｗの保持個所を下降動作することにより、植付け対象物Ｗをホルダ５から保持されていた姿勢のまま取出すことができる。
【００２５】
また、球根類植付装置１には、図２、及び図６の球根類植付装置に取付けたガイド部材の正面図に示すように、チェーン３の下降部に沿う下降ガイド２５、植付け対象物Ｗを取出す位置の下方に側面ガイド２６，２６と背面ガイド２７を設ける。下降ガイド２５は、ホルダ５の下降搬送部の外周側に近接して配置することにより、転倒姿勢のホルダ５から植付け対象物Ｗが外側方に飛び出すのを防止する。
【００２６】
側面ガイド２６，２６と背面ガイド２７は、植込み体７の先端部７ａの下降軌跡に沿うように設けていて、植込み体７の先端部７ａが植付け対象物Ｗをホルダ５から下方に取り出して圃場面Ｓに持って行くとき、植付け対象物Ｗの左右両側と背面側を植込み体７の先端部７ａの下降軌跡に沿って移動するよう案内する。また、側面ガイド２６，２６と背面ガイド２７は、ゴム等の弾性材により形成し、ガイド下部側ほど植込み体７の先端部７ａの下降軌跡に近づく姿勢で取付けることで、一層、植付け対象物Ｗのガイド機能が向上する。
【００２７】
植込み体７は、その先端部７ａに、植付け対象物Ｗの外周の一部に係合する係合部となる凹部を設けている。この植込み体７の先端部７ａがホルダ５に保持される植付け対象物Ｗの上部に係合して下方に取り出し圃場に植付けるので、ホルダ５からの取出し時から圃場への植付け時まで植付け対象物Ｗの姿勢変化が生じ難くなっている。
【００２８】
なお、三角錐状の形状の種ニンニクＷを植付けるときには、三角錐状形状の頂部ａが出芽部となるので、この頂部ａが上になるようにして圃場に植付ける。従って、チェーン３の上部でホルダ５に種ニンニクＷを装填するときには、図４，５に示されるように、頂部ａを下にして上方から押し込んで装填する。ホルダ５に装填され保持された種ニンニクＷは、チェーン３の駆動回転により下方に搬送されると、チェーン３の下部では、図１，２に示されるように、頂部ａが上になる。この姿勢のときに植込み体７が種ニンニクＷの上方から係合して下方に押出して取出し、そのまま圃場まで持って行って土中に植え込む。ここで、植込み体７の先端部７ａが、図７（ａ）のように、頂部ａが上になった姿勢の種ニンニクＷの上部が嵌り込むように円錐状凹部７ｂを形成すると、植込み体７による種ニンニクＷの保持姿勢の乱れが生じにくくなって、種ニンニクＷを適正な姿勢で植付けられる。また、図７（ｂ）の三分片７ｃ…からなる三ツ又状に形成してそのＡ―Ａ線断面図を示す図７（ｃ）のように植付け対象物Ｗの三角形状の横断面形状に合わせるように形成すると、上下軸周りの回転も抑えられ、種ニンニクＷを更に一層適正な姿勢で植付けられる。
【００２９】
以上のように構成した球根類植付装置１は、チェーン３の周回動作によりその上部位置では各ホルダ５が二つのスプロケット１１，１１の間を水平移送され、また、下部位置では各ホルダ５が逆転姿勢に転じて案内板１２に沿って水平移送される。したがって、上部位置で植付け対象物Ｗを保持手段５に逐次供給装着することによって各ホルダ５に植付け対象物Ｗを保持することができ、この植付け対象物Ｗは、その姿勢を維持したまま下部位置まで移送されて植付姿勢となり、ここで植込み体７がチェーン３の駆動回転によるホルダ５の移動と適宜タイミングを合わせて動作し、ホルダ５から植付け対象物Ｗをその姿勢のまま押し出して下降動作することにより、植付け対象物Ｗが一定姿勢で圃場の土中に押し込まれ、植付けすることができる。
【００３０】
上記構成の球根類植付装置1は、例えば、球根類植付機の側面図を図８に、その平面図を図９に示すように、自走機３１に搭載することにより球根類植付機として構成できる。自走機３１には、車高調節可能な前輪３２，３２と後輪３３，３３と後方に延びる操縦ハンドル３１ａとを機体に備え、機体後部に球根類植付装置1、１と積載台３４を配置した構成とし、また、走行速度に対して設定比率で球根類植付装置1、１が駆動回転される構成とする。なお、図例では左右に球根類植付装置１，１を配置して２条植えに構成している。また、球根類植付装置１，１の後方には、土中に植付けされた球根類の上方を覆土鎮圧する鎮圧輪３５，３５を配置する。機体の高さは、圃場面Ｓから球根類植付装置1の下部位置におけるホルダ５の下端までの高さＨが植付け対象物Ｗの高さ寸法より小さくなるように設定する。
【００３１】
球根類の植付けの際は、積載台３４に植付け対象物Ｗを積載した上で自走機３１の車高を前記高さＨに設定して走行する。操縦ハンドル３１ａの左右両側方を作業者が追従歩行しつつ、積載台３４から植付け対象物Ｗを取出して球根類植付装置１の上部位置を移送される各ホルダ５に天地逆姿勢に装填することにより、各ホルダ５に装填された植付け対象物Ｗが、植込み体７によって適正な姿勢で圃場の土中に植え込まれる。したがって、上記構成の球根類植付装置１により、特段の準備工程を要することなく、圃場において植付け対象物Ｗを逐次、保持手段５に装着する簡易な供給作業によって植付け対象物Ｗを所定の姿勢で順次圃場に植付けすることができる。

The holding means includes conveying means for transferring the planting object from the position where the planting object is loaded into the holding means to a position where the planting means takes out the planting object from the holding means, and the holding means includes the loaded planting object. A holding member that contacts while being elastically deformed along the outer peripheral surface of the head is provided, and the planted object loaded by the holding member is held so as not to change its posture.
[0006]
In the bulb planting device having the above-described configuration, when an object to be planted such as a bulb or a seed bud is loaded into the holding means, the holding member of the holding means is elastically deformed along the outer peripheral surface of the loaded planting object. Touching and holding the planted object so as not to change its posture. The planting object loaded and held in the holding means is transported by the transporting means, and the planting object transported to the set position is taken out of the holding means by the planting means and planted in the field.
[0007]
The invention according to claim 2 is the bulbous planting apparatus according to claim 1, wherein the holding member of the holding means is a large number of elastically deformable plants that are planted so that the hair tips are directed to the loading site of the planting object. It is characterized by comprising a napped body.
[0008]
In the bulbous planting device configured as described above, the hair tips of many napped bodies come into contact with each other while being elastically deformed along the outer peripheral surface of the loaded planting object, and the posture of the loaded planting object is changed. Do not hold.
[0009]
【The invention's effect】
The present invention has the following effects.
Since the invention according to claim 1 is configured as described above, an object to be planted such as bulbs such as seed garlic and moss such as seed pods in the field without requiring a special preparation step before planting work. It can be planted in a field with a predetermined posture simply by loading it into the holding means.
[0010]
In the invention according to claim 2, since the holding member is constituted by a large number of elastically deformable napped bodies planted so that the hair tips face the loading portion of the planting object, the holding member has a simple configuration. Regardless, the planting object can be held appropriately so as not to change the posture, and the planting means can accurately take out the planting object from the holding means.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.
[0012]
FIG. 1 is a front view of the bulb planting apparatus, FIG. 2 is a sectional view taken along the line AA, and FIG. 3 is a sectional view taken along the line BB. 1 to 3, a bulb planting apparatus 1 includes a holding means (holder 5) for holding an object to be planted W such as a bulb or a seed pod, and the planting object W is taken out from the holding means 5 and planted in a field. The planting means (planted body 7) to be attached and the holding means 5 are transported from a position where the planting object W is loaded into the holding means 5 to a position where the planting means 7 takes out the planting object W from the holding means 5 The holding means 5 includes a holding member 22 that comes in contact with the outer peripheral surface of the planted object W loaded while being elastically deformed, and is loaded by the holding member 5. The planting object W is configured to be held so as not to change its posture.
[0013]
Therefore, in the bulb planting apparatus 1 configured as described above, when the planting object W such as a bulb or a seed pod is loaded on the holding unit 5, the holding member 22 of the holding unit 5 is loaded. It contacts while elastically deforming along the outer peripheral surface, and holds the planted object W loaded so as not to change its posture. The planting object W loaded and held in the holding means 5 is transported by the transporting means 3, and the planting object W transported to the set position is taken out from the holding means 5 by the planting means 7 and planted in the field. . In this way, in the field, without any special preparation steps before planting, the field can be placed in a predetermined posture by simply loading the holding means with planting objects such as bulbs such as seed garlic and moss such as seed buds. It is possible to plant bulbs, mosses and the like efficiently and accurately.
[0014]
The holding means 5 is configured so that the planting object W can be loaded from above at the position where the planting object W is loaded, and the planting object W is placed downward at the position where the planting means 7 takes out the planting object W. Further, at this time, a space (gap G) is formed in which the planting means 7 enters the holding portion of the planting object W of the holding means 5 from above and can move downward. The planting means 7 is provided with an engaging portion that engages with a part of the planting object W. As a result, the planting object W is pushed and loaded from above the holding means 5, and the planting means 7 moves from above the holding means 5 and descends in the holding means 5, at this time. Then, the engaging portion of the planting means engages with the upper part of the planting object W held by the holding unit 5 and pushes the planting object W downward. The taken-out planting object W is held in a posture in which the upper part engages with the engaging portion of the planting means and is taken out and brought into the soil and planted.
[0015]
The holding member 22 of the holding means 5 can be made of a foamed material such as sponge, but as shown in the figure, the elastic deformation is planted so that the hair tip faces the loading site of the planting object W. Even if it is composed of a large number of napped bodies, it is possible to hold the planting object accurately so that the posture of the planting object does not change, and the planting means can accurately hold the planting object from the holding means. Can be taken out.
[0016]
The conveying means 3 is configured to rotate up and down, and the planting object W is loaded into the holding means 5 at the upper part of the circumference, and the planting means 7 takes out the planting object W from the holding means 5 at the lower part of the circumference and enters the field. By adopting the planting configuration, the planting object W can be loaded onto the holding means 5 at a high position from the farm scene S. Therefore, when the planting object W is loaded manually, the loading operation is easy and efficient. Since the planting means 7 can take out the planting object W from the holding means 5 at a position close to the farm scene S, the planting means can be taken out from the holding means 5 and then into the soil of the field. The stroke in which 7 takes the planting object W is shortened, and the posture disorder in the stroke is less likely to occur, and the planting accuracy is improved. Moreover, the operating range of the planting means 7 can be reduced, and the body can be made compact.
[0017]
The planting means 7 is provided with an engaging portion that engages with a part of the planting object W at the tip 7 a, and the tip 7 a of the planting means 7 is above the planting object W held by the holding means 5. Is engaged with the upper part of the planting object W and descends into the soil of the field, so that the planting means 7 takes out the planting object W from the holding means 5 in the holding posture and enters the field. It is designed to be planted.
[0018]
In addition, when the holding means 5 is fixed to the conveying means 3 configured as described above and circulates, the holding means 5 places the planting object W from above at the position where the planting object W is loaded as described above. When the planting means 7 is configured to be able to be taken out at the position where the planting means 7 takes out the planting object W, the planting object W can be held when being loaded into the holding means 5. The posture and the holding posture of the planting object W when taken out by the planting means 7 are upside down. Therefore, when loading into the holding means 5, the planting object W is loaded into the holding means 5 in a posture in which the upper side after planting is the lower side. Then, when the holding means 5 is transported to a position where the planting means 7 takes out the planting object W, the holding means 5 is turned upside down when held at the upper part of the transport means 3 and is held by the holding means 5. The planting object W to be planted has an appropriate vertical posture, and the planting means 7 takes out the planting object W in this posture and implants it in the field.
[0019]
Further, the bulbous planting device 1 is configured to be mountable on a self-propelled machine, so that it can be planted continuously while moving in the field.

The configuration of the example will be described in detail. The chain 3 as a conveying means is hung around two sprockets 11 and 11 that are arranged at substantially the same height, one of which is driven to rotate and the other is driven to rotate, and a guide plate 12 that is arranged substantially horizontally below. It is provided to rotate. The guide plate 12 is a guide that horizontally feeds the chain 3 at a lower position close to the farm scene S. Thereby, the conveying means includes an upper lateral movement part between the two sprockets 11, a lower movement part continuing downward from the right end thereof, a lower lateral movement part below the guide plate 12 adjacent to the farm scene S, and an upper part. The lateral movement part has a substantially triangular orbit around the upper movement part that rises obliquely. As will be described later, the holder 5 includes a holding member 22 made of a raised body or the like that comes in contact with the outer peripheral surface of the planted object W loaded while being elastically deformed, and is fixed to the link of the chain 3.
[0021]
The implant 7 is freely attached to a shaft 14a attached to the distal end portion of a drive arm 14 that is attached to a drive rotary shaft that projects from the support frame 13 and rotates, and a support shaft that projects from another part of the support frame 13. The rotating arm 15 is rotatably attached to a shaft attached to the tip of the rotating arm 15 so that the tip 7a of the implant 7 draws a vertically elliptical locus T by the driving rotation of the driving arm 14. Operates up and down. And the front-end | tip part 7a of the implantation body 7 sets to the positional relationship which passes the holding | maintenance part of the planting target W of the holder 5 in the lower position of the chain 3 from the top to the bottom, and transfer of each holder 5 by the chain 3 By operating the driving arm 14 in synchronism with the movement, the tip 7a of the implant 7 pushes out the planting object W held by the holder 5 from the top to the bottom while maintaining the posture, and the implant 7 With the momentum of the operation, the planted object W is brought to the farm scene S while being held by the tip 7a in the posture and pushed into the soil for planting.
[0022]
When the planting means 7 takes out the planting object W from the holding means 5, the conveying means 3 stops, and after the planting means 7 removes the planting object W, the next holding means 5 takes out by the planting means 7. If the conveying means 3 is driven intermittently so that the conveying means 3 moves to a position, the planting means 7 can take out the planting object W from the holding means 5 more satisfactorily. Accuracy is improved.
[0023]
The holder 5 will be described in detail. FIG. 4 is an enlarged perspective view of the holder, and FIG. 5 is an enlarged cross-sectional view of a state in which the planting object W is mounted on the holder. A substantially ring-shaped (C-shaped) base member 21 that is open, and a large number of elastically deformable napped bodies planted from the base member 21 toward the center side of the ring-shaped shape. A holding member 22 is provided. The base member 21 is attached to the conveying means (chain 3) via the attachment member 5a in a posture in which an axis substantially orthogonal to the center side of the ring shape is substantially orthogonal to the conveying direction of the conveying means (chain 3). In FIG. 4, the tip 7 a side of the planting body 7 passes from the top to the bottom through the gap G that is the open portion of the base member 21 formed on the front side.
[0024]
The planting object W held by the holder 5 moves the planting object W by lowering the holding portion of the planting object W in the holder 5 against the holding force by the holding member 22. Can be taken out from the holder 5 as it is.
[0025]
Further, the bulb planting device 1 includes a descending guide 25 along the descending portion of the chain 3, an object to be planted, as shown in front views of the guide member attached to the bulb planting device of FIGS. 2 and 6. Side guides 26 and 26 and a rear guide 27 are provided below the position where W is taken out. The descending guide 25 is disposed close to the outer peripheral side of the descending conveyance unit of the holder 5, thereby preventing the planting object W from jumping outward from the holder 5 in the falling posture.
[0026]
The side guides 26, 26 and the back guide 27 are provided along the descending locus of the tip 7 a of the implant 7, and the tip 7 a of the implant 7 takes out the planting object W from the holder 5 downward. When taking it to the surface S, the left and right sides and the back side of the planted object W are guided to move along the downward trajectory of the tip 7a of the planted body 7. Further, the side guides 26, 26 and the rear guide 27 are formed of an elastic material such as rubber, and are attached in a posture closer to the descending locus of the distal end portion 7a of the implant 7 toward the lower part of the guide, thereby further increasing the planting object W. The guide function is improved.
[0027]
The implanted body 7 is provided with a concave portion at its distal end portion 7a that serves as an engaging portion that engages with a part of the outer periphery of the planted object W. Since the tip 7a of the planted body 7 engages with the upper portion of the planted object W held by the holder 5 and is taken out downward and planted in the field, the planting object is taken from the time of removal from the holder 5 to the time of planting in the field. The posture change of the object W is difficult to occur.
[0028]
In addition, when planting the seed garlic W having a triangular pyramid shape, since the apex a having the triangular pyramid shape becomes a budding portion, the seed garlic W is planted on the field with the apex a facing upward. Therefore, when the seed garlic W is loaded into the holder 5 at the upper part of the chain 3, as shown in FIGS. When the seed garlic W loaded and held in the holder 5 is conveyed downward by the drive rotation of the chain 3, the top part “a” is at the top, as shown in FIGS. In this posture, the planted body 7 engages from above the seed garlic W, pushes it downward, takes it out, takes it to the field as it is, and implants it in the soil. Here, when the tip 7a of the implant 7 forms a conical recess 7b so that the upper part of the seed garlic W with the top a facing up as shown in FIG. The disorder of the holding posture of the seed garlic W due to 7 is less likely to occur, and the seed garlic W can be planted in an appropriate posture. Further, it is formed into a three-pronged shape composed of the three-piece pieces 7c... Of FIG. 7 (b), and the cross-sectional view taken along line AA is shown in FIG. If it forms so that it may match, rotation around an up-and-down axis is also suppressed and seed garlic W is planted in a still more appropriate posture.
[0029]
In the bulb planting apparatus 1 configured as described above, each holder 5 is horizontally transported between the two sprockets 11 and 11 at the upper position by the revolving operation of the chain 3, and each holder 5 is moved at the lower position. It turns into a reverse rotation posture and is horizontally transferred along the guide plate 12. Therefore, the planting object W can be held in each holder 5 by sequentially supplying and mounting the planting object W to the holding means 5 at the upper position, and the planting object W is in the lower position while maintaining its posture. The planted body 7 is moved to the planting posture, and the planted body 7 operates in time with the movement of the holder 5 due to the drive rotation of the chain 3 as appropriate, and the planted object W is pushed out from the holder 5 in that posture and lowered. By doing so, the planting object W is pushed into the soil of the field in a fixed posture and can be planted.
[0030]
The bulb planting apparatus 1 having the above-described configuration is, for example, mounted on a self-propelled machine 31 as shown in FIG. 8 as a side view of the bulb planter and as shown in FIG. Can be configured as a machine. The self-propelled aircraft 31 is provided with front wheels 32, 32 and rear wheels 33, 33 that can adjust the vehicle height, and a steering handle 31a that extends rearward. The bulb planting devices 1 and 1 and the loading platform 34 are provided at the rear of the aircraft. The bulb planting devices 1 and 1 are driven and rotated at a set ratio with respect to the traveling speed. In the illustrated example, the bulb planting devices 1 and 1 are arranged on the left and right sides to form a two-row planting. Further, on the rear side of the bulb planting devices 1, 1, pressure-reducing wheels 35, 35 are arranged to cover the upper part of the bulbs planted in the soil. The height of the airframe is set so that the height H from the farm scene S to the lower end of the holder 5 at the lower position of the bulbous planting device 1 is smaller than the height dimension of the planting object W.
[0031]
When planting bulbs, the planted object W is loaded on the loading table 34 and the vehicle height of the self-propelled aircraft 31 is set to the height H to travel. While the operator follows the left and right sides of the steering handle 31a, the planting object W is taken out from the loading table 34 and loaded in the upside down posture on each holder 5 to which the upper position of the bulbous planting device 1 is transferred. Thus, the planting object W loaded in each holder 5 is planted in the soil of the farm field in an appropriate posture by the planting body 7. Therefore, the bulbous planting device 1 having the above-described configuration allows the planting object W to be placed in a predetermined posture by a simple supply operation in which the planting object W is sequentially attached to the holding means 5 in the field without requiring any special preparation process. Can be planted sequentially in the field.
