Description

【0001】
【発明の属する技術分野】
本発明は、主に、地面に杭、支柱等を立てるための穴を形成する穴あけ機に関する。
【0002】
【従来の技術】
地面に所定の間隔で穴を掘削する穴あけ機としては、トラクタに3点リンク手段を介して装着された支持枠に、オーガを昇降自在に有する穴あけ機構を設けると共に、杭等を載置するため荷台を水平方向に突出状に設け、例えば穴あけ機構によりあけた穴に杭等を挿入して立てるようにしたものがある。
【0003】
【発明が解決しようとする課題】
しかし、従来この種の穴あけ機では、トラクタから取り外したとき自立することができるようにするために、支持枠の左右両側に、左右一対のスタンドを設けると共に、荷台の突出端部に左右一対のスタンドを設け、これらスタンドを下方に突出するスタンド姿勢と水平方向等に突出する折り畳み姿勢とに姿勢変更自在に支持するようにしたものある。
従って、従来では、荷台側にも、スタンドを設ける必要があり、スタンドの構成部材が多く必要になり、穴あけ機全体の製造が面倒でかつ製造費が高く付いた。
【0004】
本発明は上記問題点に鑑み、穴あけ機をトラクタから外しても安定に自立させることができると共に、荷台側に設けるスタンドを省略できるようにし、スタンドの構成部材を少なくして製造容易でかつ安価に提供できるようにしたものである。
【0005】
【課題を解決するための手段】
この技術的課題を解決するための本発明の技術的手段は、トラクタ2に3点リンク手段3を介して支持枠4が装着され、この支持枠4に、オーガ35を昇降自在に有する穴あけ機構6が設けられると共に、荷台20が設けられた穴あけ機において、
前記荷台20は、荷を載置する荷台姿勢Aと、支持枠4を自立させるように支えるスタンド姿勢Bとに姿勢変更自在に設けられ、荷台20を荷台姿勢Aとスタンド姿勢Bとに着脱自在に固定する固定手段50が設けられている点にある。
【0006】
本発明の他の技術的手段は、前記支持枠4の左右両側に、下方突出してスタンド姿勢になるスタンド23が設けられ、荷台20は、その先端部が接地するように傾斜することによりスタンド姿勢Bになるように構成され、前記スタンド23とスタンド姿勢Bの荷台20とで、支持枠4を自立させるように支えるようにした点にある。
本発明の他の技術的手段は、前記荷台20は、支持枠4側に対して、取付ピン31によりそのピン軸廻りに回動自に支持されることにより、水平方向に突出する荷台姿勢Aと、後上がり方向に傾斜するスタンド姿勢Bとに姿勢変更自在に取付られている点にある。
【0007】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
図1〜3において、1はトラクタ2に3点リンク手段3を介して装着された穴あけ機であり、3点リンク手段3は左右一対のロアリンク3Aと1本のトップリンク3Bとを有し、穴あけ機1は、例えば3本の縦部材4Aを上下の横部材4Bで連結して四角枠形状に形成した支持枠4を有している。前記3点リンク手段3は、トラクタ2の油圧装置5によって昇降自在であり、油圧装置5は、リフトアーム5aとリフトロッド5bとを有し、支持枠4の垂直度(傾斜角度)は3点リンク手段3で調整できる。なお、11はトラクタ2の後輪である。
【0008】
図1及び図2において、前記支持枠4の前面には、下部の左右両側にロアリンク連結部7を、中途高さの左右中央にトップリンク連結部8をそれぞれ設けており、左右各ロアリンク連結部7にはロアリンク3Aが連結され、トップリンク連結部8にはトップリンク3Bが連結されている。
また、支持枠4は前面のトップリンク連結部8より上方の位置には、穴あけ機構6を操作するために操作手段9が設けられている。この操作手段9は、トラクタ2の油圧ポンプから後述する油圧モータ16及び油圧シリンダ17へ供給する圧油を制御する。
【0009】
前記操作手段9は、支持枠4の前面の右又は左の縦部材4Aに装着しておいてもよいが、穴あけ機構6が左右位置変更可能であるので、作業者がトラクタ2上から左右どちら側から後を振り向いても、容易に操作できるように、中央に配置している。
前記穴あけ機構6は、上下支持板26をミガキ棒等の杆材で形成された前後一対のガイド部材18で連結し、上下支持板26から側方へ支持腕15を突出して機枠12が形成されており、支持腕15の先端が支持枠4の上下横部材4Bに設けた取付け板27に、縦軸13を介して揺動自在に支持されている。
【0010】
上下取付け板27は上下横部材4Bより後方に突出しており、支持腕15は横部材4Bと重合する高さに位置し、上下各取付け板27は上下2枚の板で形成され、支持腕15を上下に挟んでいる。
上取付け板27と支持腕15との間には、穴あけ機構6を左右一方に揺動(オフセット)した位置で固定するロック手段14が設けられている。このロック手段14はロックピン14A及び上取付け板27に形成したピン穴14B等で形成され、図2に実線で示すように、穴あけ機構6を左側に揺動して、支持腕15を横部材4Bの左側部分と重合した状態で、取付け板27及び支持腕15にロックピン14Aを貫通することにより、穴あけ機構6の位置を固定する。
【0011】
穴あけ機構6を右側へ位置変更する場合は、ロックピン14Aを抜いてロック手段14を解除して、穴あけ機構6を縦軸13回りに揺動し、揺動した支持腕15と取付け板27の右側のピン穴14Bとにロックピン14Aを貫通する(図2に2点鎖線で示す)。
前記穴あけ機構6は、一対のガイド部材18に昇降台28が摺動昇降自在に支持されており、この昇降台28は上下2枚の板材28Aとガイド部材18に嵌合する嵌合部材28B等で形成されていて、その左右方向外側部分には油圧モータ16が取付けられ、また、昇降台28の左右方向内側部分には油圧シリンダ17のシリンダチューブ17Aの下部が連結されている。
【0012】
前記油圧シリンダ17は、ピストンロッド17Bの先端(下端)が下側の取付け板27に連結され、伸縮によってシリンダチューブ17Aが上下動するようになっており、シリンダチューブ17Aの上下動により、昇降台28を介して油圧モータ16が昇降される。
前記油圧モータ16の出力軸16Aには、オーガ(ドリル)35が連結具を介して着脱自在に連結されている。このオーガ35は形成する穴の径等に応じて変更することができる。
【0013】
29は機枠12に設けられたカバーであり、油圧モータ16、ガイド部材18及び昇降台28の周囲を覆っている。
支持枠4の下部には、長尺物19載置用の荷台20が後方突出状に設けられ、支持枠4の背面上部には、長尺物倒れ防止用のガイド手段21が設けられている。左右一対のロアリンク連結部7に、荷台20が前後取付ピン31、32によって連結されている。
図示の穴あけ機1は防風ネットの杭立て作業に最適に構成されたものである。例えば、馬鈴薯やたばこ等の新芽は風によって損傷を受け易いので、畝に沿って防風ネットを張る必要があり、その防風ネットは畝に沿って一定間隔で穴をあけ、その穴に杭を立て、その杭に防風ネットを取付けるようになっている。従って、前記長尺物19は例えば、防風網を取付けるための杭(支柱)である。
【0014】
前記荷台20は、オーガ35によって形成した穴に挿入する長尺物19を、穴あけ作業と並行して運ぶことができるように、また、穴から抜き取った長尺物19を運ぶことができるように設けられている。
前記穴あけ機構6は、オーガ35を最上位置まで上昇させたときにオーガ35の下端は荷台20より上方になるように構成されており、荷台20が存在しても、オーガ35を左右位置変更可能である。
前記荷台20は、図4及び図5に示すように、底壁51と左右一対の側壁52と前壁53と後壁54とを有する箱状に形成され、荷台20の底壁51は多数の孔22を有する多孔材で形成されている。穴に挿入する長尺物19は下端部が尖端形状になっており、前記底壁51の孔22は長尺物19の尖端と係合して、移動中の振動により長尺物19がズレ動かないように規制し、また、穴から抜き取った長尺物19に付着していた土が落ちても、底壁51の孔22から地上に落ちて、荷台20内に溜まらないようにしている。
【0015】
荷台20の先端部側の下面には、底壁51の左右端縁部に沿う左右一対の左右補強杆56と左右一対の補強杆56を連結する連結杆57とを有する補強部材58が溶接等に固着されている。荷台20先端部は前記補強部材58を介して接地するため、荷台20の底壁51等に接地により摩耗や破損が生じるのを防ぐことができる。
また、支持枠4の左右両側に、下方突出してスタンド姿勢になる左右一対のスタンド23が設けられている。この左右一対のスタンド23は、一対の取付ピン41,42により、左右一対のロアリンク連結部7の前側下端に、支持枠4から下方に突出するスタンド姿勢と、支持枠4から後方に突出する折り畳み姿勢とに姿勢変更自在に設けられている。即ち、一方(前側又は上側)の取付ピン41を外して、スタンド23を他方の取付ピン42を中心に回動し、前記取り外した一方の取付ピン41を、取付ピン42よりも上方位置又は前方位置に形成したロアリンク連結部7の取付孔に挿入し直すことにより、スタンド23を鎖線で示すスタンド姿勢と実線で示す折り畳み姿勢に保持固定できるように構成されている。
【0016】
図5、図6に示すように、ロアリンク連結部7に、前取付ピン31が挿通される前取付孔45が設けられると共に、後取付ピン32が挿脱自在に挿通される上部後取付孔46と下部後取付孔47とが設けられている。荷台20の左右一対の側壁52の前部に、前取付ピン31が挿入される前取付孔48が、ロアリンク連結部7の前取付孔45に対応するように設けられると共に、後取付ピン32が挿入される後取付孔49が、ロアリンク連結部7の上部後取付孔46及び下部後取付孔47に対応するように設けられている。
【0017】
前取付ピン31をロアリンク連結部7の前取付孔45と荷台20の前取付孔45とに挿入し、後取付ピン32をロアリンク連結部7の上部後取付孔46と荷台20の後取付孔49に挿入することによって、前後取付ピン31,32により、荷台20は、支持枠4から水平方向に後方突出する荷台姿勢Aに固定されるようになっている。また、後取付ピン32を上部後取付孔46及び後取付孔49から取り外して、荷台20を前取付ピン31廻りに下方揺動して、ロアリンク連結部7の上部後取付孔46と荷台20の後取付孔49に挿入することによって、前後取付ピン31,32により、荷台20は、荷台20の先端部(後端部)が接地するように支持枠4から後下がりに傾斜したスタンド姿勢Bに固定できるようになっている。
【0018】
従って、荷台20は、支持枠4側に対して、前取付ピン31によりそのピン軸廻りに回動自に支持されることにより、水平方向に突出する荷台姿勢Aと、後上がり方向に傾斜するスタンド姿勢Bとに姿勢変更自在に取付られ、後取付ピン32の着脱によって、荷台20は、水平方向に突出する荷台姿勢Aと、荷台20の先端部が接地して支持枠4を自立させるように支えるスタンド姿勢Bとに姿勢変更自在とされ、荷台20を荷台姿勢Aとスタンド姿勢Bとに着脱自在に固定する固定手段50が、後取付ピン32、後取付孔49、上部後取付孔46及び下部後取付孔47によって構成されている。そして、前記左右一対のスタンド23とスタンド姿勢Bの荷台20とで、支持枠4を自立させるように支えるようになっており、穴あけ機1を使用しないとき、スタンド姿勢にした左右一対のスタンド23とスタンド姿勢にした荷台20とで、支持枠4を自立させるように支えて、穴あけ機1を自立させる。
【0019】
穴あけ機1は、スタンド23とスタンド姿勢の荷台20とで自立させたとき、ロアリンク連結部7及びトップリンク連結部8の高さが適正になって、穴あけ機1に対する3点リンク手段3の着脱が容易になる。
長尺物倒れ防止用ガイド手段21は、支持枠4の左右縦部材4Aの上端に、側面視略L字状のパイプ34を着脱自在に連結し、両パイプ34の後上端にチェーンを着脱自在に張れるようにしており、長尺物19の上部が左右方向及び後方へ倒れるのを規制する。
【0020】
前記穴あけ機1による穴あけ作業は、穴あけ機1がスタンド23及びスタンド姿勢Bの荷台20を介して自立設置している状態で、トラクタ2を近づけて3点リンク手段3を支持枠4に連結し、そして、3点リンク手段3を油圧装置5で上昇させ、スタンド23を折畳み、圃場の畝に跨る状態に配置する。
その後、畝間溝内のトラクタ2の後輪11の後方に穴あけ機構6を配置し、3点リンク手段3を介して支持枠4を下降して、最上位置のオーガ35の高さを畝間溝の底から数cmの高さ(走行に支障のない高さ)まで下降させる。3点リンク手段3によって支持枠4を傾斜させることができるが、一般的にはオーガ35を垂直に配置する。
【0021】
この状態で油圧モータ16を駆動してオーガ35を回転させながら、油圧シリンダ17を作動してオーガ35をガイド部材18に沿って下降させる。オーガ35は、例えば実施形態で、70cm前後の深さの穴を地面に形成できる。
1つの穴を掘削後、トラクタ2を若干前進させ、荷台20上から長尺物19を取り出して前記穴に挿入して立てる。前記穴から所要間隔をおいた位置までトラクタ2を前進させ、次の穴を形成する。
長尺物19を抜く場合は、杭打ち手順とは逆に、抜いた長尺物19を荷台姿勢にした荷台20に載せながら、トラクタ2を後進させればよい。
【0022】
なお、本発明は前記実施の形態に限定されるものではなく、種々変形することができる。例えば、穴あけ機1は、トンネルハウスの支柱を立てるための穴、又は長芋等の植物の植付け用穴等を形成するのに使用したりしてもよく、穴あけ機構6は支持枠4の左右一側又は両側に固定的に取付けたりしてもよい。
また、前記実施の形態によれば、左右一対のスタンド23が設けられ、左右一対のスタンド23とスタンド姿勢Bの荷台20とで、支持枠4を自立させるように支えるようにしているが、これに代え、左右一対のスタンド23を省略し、例えば、支持枠4の下端部を接地させ、この支持枠の下端部とスタンド姿勢Bの荷台20とで、支持枠4を自立させるように支えるようにしてもよい。
【0023】
【発明の効果】
本発明によれば、荷台20をスタンド姿勢Bに姿勢変更して固定することにより、荷台20を穴あけ機1を自立させるためのスタンドとして兼用することができる。従って、荷台20を有効に利用して、穴あけ機1を確実に自立させることができるようになる。しかも、従来、荷台20側等に設ける必要のあったスタンドの構成部材を省略することができ、穴あけ機20を製造容易でかつ安価に提供することができる。
