【産業上の利用分野】
この発明は、複数条植えの苗植装置を備えた苗植機に関する。
【0002】
【従来の技術とその問題点】
苗植機は、苗植装置の植付条数が多くなるほど左右幅が広くなり、運搬時や格納時にスペースをとり、効率が悪いとの問題がある。
【0003】
なお、実開昭56−10319号公報に、苗植装置を左右中央側部分と右側部分と左側部分とに三つに分割可能に構成し、苗植装置の左右中央側部分に対して左右両側部分を左右内側に移動可能に設けたものが示されている。このものは、苗植装置の左右中央部分が固定部となるから、その分、苗植装置の左右幅の縮小が制限される。
【0004】
【課題を解決するための手段】
この発明は、上記の問題点を解決するために、植付条数に対応した複数の苗植付具(7)を支持する伝動ケ−ス(5)を備え苗植装置(2)を走行車体(1)の後側にリンク(3)を介して上下動可能に装着し、苗植装置(2)の苗載台(6)をロ−ラ(47)を介して左右の支柱(45)により左右移動可能に支持し、前記伝動ケ−ス(5)からの動力で前記苗載台(6)を左右移動させて苗を苗植付具(7)の苗取口へ1株分づつ供給する構成とした苗植機において、前記苗載台(6)、伝動ケ−ス(5)及び複数の苗植付具(7)を左右中央から右側と左側との二つの分割ユニットに分割可能に設け、前記リンク(3)の後部に中央枠(8)を取付ける一方、前記苗載台(6)、伝動ケ−ス(5)及び複数の苗植付具(7)からなる分割ユニットの分割位置の左右にそれぞれ軸(13)を設け、中央枠(8)に対して前記軸(13)回りにそれぞれ回動可能に側部杆(12)を一対連結し、該左右の側部杆(12)にそれぞれ前記伝動ケ−ス(5)及び支柱(45)を設け、該支柱(45)に支持させたまま前記ロ−ラ(47)により苗載台(6)の分割部分の一方を他方に対して離れる方向に左右移動可能に構成し左右の側部杆(12)の前記軸(13)回りの回動によって、前記分割ユニットを走行車体(1)の後方において横向き姿勢に変更させて苗植装置(2)全体の左右幅が狭くなるように移動可能に構成したことを特徴とする苗植機としたものである。
【0005】
【作用】
この苗植機は、苗植作業を行わないときには、支柱(45)に支持させたままロ−ラ(47)により苗載台(6)の分割部分の一方を他方に対して離れる方向に左右移動させてから、苗載台(6)、伝動ケ−ス(5)及び複数の苗植付具(7)からなる分割ユニットの分割位置の左右に設けたそれぞれの軸(13)回りに側部杆(12)を回動させ、前記分割ユニットを走行車体(1)の後方において横向き姿勢に変更させて苗植装置(2)全体の左右幅が狭くなるように移動できる。
【0006】
【発明の効果】
よって、支柱(45)に支持させたままロ−ラ(47)により苗載台(6)の分割部分の一方を他方に対して離れる方向に左右移動させてから、苗載台(6)、伝動ケ−ス(5)及び複数の苗植付具(7)からなる分割ユニットの分割位置の左右に設けたそれぞれの軸(13)回りに回動させて前記分割ユニットを横向き姿勢に変更させるものであるから、苗載台(6)の分割部分の一方を支柱(45)に支持させた状態で軽い力で容易に左右移動できる構成としながら、この左右移動により苗載台(6)の左右の互いの分割部分が該分割部分の回動の支障にならず、前記分割ユニットの回動を比較的軽い力で容易に行える位置に前記軸(13)を配置することができ、従来のものに比較して苗植装置(2)の左右幅を著しく狭くでき、効率良く運搬や格納ができる。
【0007】
【実施例】
つぎに、この発明の実施例を説明する。図1のように、走行車体(1)の後に8条植の苗植装置(2)がリンク(3)で装着されて乗用型の苗植機となっている。シリンダ(4)が走行車体(1)に取付けられ、これから突出したピストンロッドが上側のリンク(3)に接続し、ピストンロッドの出没でリンク(3)の後端が上下し、これにともなって苗植装置(2)が上下に移動するように出来ている。その苗植装置(2)は、中心から左右に位置している4条植ごとの伝動ケース(5)、苗載台(6)および苗植付具(7)にて左右にユニット構成されている。
【0008】
図1、図2および図3のように、中央枠(8)が前後方向のローリング軸(9)でリンク(3)の後部の縦枠(10)に回動自在に取付けられている。中央杆(11)が中央枠(8)の上部に横向に固定され、その両端に側部杆(12)が軸(13)の回りに回動するように取付けられている。一対の側部枠(14)が中央枠(8)と平行にそれぞれの側部杆(12)に固定されている。
【0009】
一対の横移動シリンダ(15)がそれぞれの側部枠(14)に横向に固定され、これから外側に突出するピストンロッド(16)の先に可動枠(17)が固定され、シリンダ(15)の内側にオイルを供給すると、可動枠(17)が外側に向って横移動し、その外側にオイルを供給すると、この可動枠(17)が内側に向って横移動するように出来ている。一対の案内棒(18)が可動枠(17)から側部枠(14)を通って中央枠(8)側に延び、その先が円錐状に形成され、上記の移動で、中央枠(8)に固定された管(19)の孔に出入りするようになっている。
【0010】
中央部に回動シリンダ(20)が配置され、その端と、これから突出するピストンロッド(21)の端が、それぞれの側部杆(12)から突出するアーム(22)の突端に回動自在に取付けられ、回動シリンダ(20)の左室にオイルが供給されると、ピストンロッド(21)が突出して側部杆(12)が軸(13)の回りに回動して中央杆(11)に対して折れ曲がり、回動シリンダ(20)の右室にオイルを供給すると、ピストンロッド(21)が引き戻され、側部杆(12)が中央杆(11)に対して直線状に戻るようになっている。
【0011】
中央歯車箱(23)が中央枠(8)の下方に板(24)で固定され、その入力軸(25)がプロペラシャフト(26)で走行車体(1)の出力軸につながり、走行車体(1)のエンジンの動力で回転するようになっている。両横に爪(27)を備えた軸(28)が中央歯車箱(23)の後部に配置され、傘歯車で入力軸(25)につながって回転するようになっている。
【0012】
一対の伝動ケース(5)の先端がそれぞれの可動枠(17)の後の面に固定され、横軸(30)が内端を外に突出してその前部に配置され、可動枠(17)が外に向って移動すると、その内端の爪(31)が上記の爪(27)から離れ、内に向って移動すると、爪(31)が爪(27)に咬み合うように出来ている。図2および図4のように、それぞれの伝動ケース(5)の両横から一対の植付ケース(32)が後に伸び、その後部の左右両側に旋回ケース(33)が取付けられ、それぞれの旋回ケース(33)の両端に苗植付具(7)が取付けられて、左右2つの苗植駆動装置(34)にて8条植のロータリー式の苗植装置(2)を構成している。歯輪(35)が横軸(30)に固定され、旋回軸(36)に固定された歯輪(37)と上記の歯輪(35)とにチエン(38)が巻き掛けられ、旋回軸(36)の両端で旋回ケース(33)が回転すると、その内の遊星歯車で苗植付具(7)が同じような姿勢を保って旋回するように出来ている。一対の横移動棒(39)がそれぞれの伝動ケース(5)に摺動自在に支えられている。リードカム(40)が歯輪(41)(42)とチエン(43)で横軸(30)に接続し、これの回転で、横移動棒(39)が左右に往復するようになっている。
【0013】
図1および図2のように、断面がL型をした一対の苗受板(44)がそれぞれの組の植付ケース(32)の上部に設けられている。一対の苗載台(6)がその下端をそれぞれの苗受板(44)の上端に載せるようにして前倒れの斜に設けられている。それぞれ一対の支柱(45)が側部杆(12)から苗載台(6)の裏で上に伸び、その上端に横管(46)が固定されている。ローラ(47)が苗載台(6)の裏面の上端に取付けられて上記の横管(46)に係合し、コ字型の受具(48)がその下端に取付けられて苗受板(44)の角部(49)に係合し、苗載台(6)がこの両者で支えられて左右に移動し得るようになっている。それぞれの横移動棒(39)の両端が連杆(50)で苗載台(6)の裏面につながり、横移動棒(39)の往復で、この苗載台(6)も同方向に往復するように出来ている。
【0014】
なお、旋回ケース(33)は、図1で反時計方向に旋回する。そして、それぞれの苗植付具(7)は、同じような姿勢で旋回し、その先端が苗受板(44)に欠ぎ込まれて出来ている苗取口を上から下に向って通るように配置されている。従って、マット状の苗を苗載台(6)に載せて運転すると、この苗は、下端が苗受板(44)上に載って左右に移動し、この移動中に苗取口上において苗植付具(7)の先で1株分ごとに欠ぎ取られる。
【0015】
また、軸(13)は、中央寄りで苗載台(6)と同じような角度にその下に設けられている。従って、苗植作業を終了したようなとき、それぞれの横移動シリンダ(15)からピストンロッド(16)を突出させ、つづいて回動シリンダ(20)からピストンロッド(21)を突出させる。すると、可動枠(17)とともに左右の伝動ケース(5)と苗載台(6)が外側に移動して爪(31)が爪(27)から離れるとともに、案内棒(18)の先が管(19)から離れ、これにつづいて、側部枠(14)が軸(13)の回りに回動し、可動枠(17)、伝動ケース(5)および苗載台(6)が、それぞれ斜め後ろ上方に上る方向に回動して折りたたまれる。なお、横移動シリンダ(15)でピストンロッド(16)が押し出されて苗載台(6)が外側に移動するとき、支柱(45)が移動しないので、苗載台(6)の上端は、ローラ(47)が横管(46)上を転動して外側に移動する。折り曲げられた上記のユニットを元に戻すときは、上記の逆に作動する。
【0016】
図1のように、中央枠(8)の後部から支杆(51)が斜後下に伸び、後端に横軸(52)が取付けられ、これからアーム(53)が伸びてその下端に中央フロート(54)の後部が取付けられ、アーム(53)の後部の上下動で苗の植付深さが調節出来るようになっている。この中央フロート(54)は、上から見てT字形に形成され、中央部の左右の苗植付具(7)の前方の泥土を整地するようになっている。この中央フロート(54)の先端が泥面を滑走している際に上下に移動すると、シリンダ(4)に対してオイルが供給或は排出され、作業中の苗植装置(2)が泥面に対して一定の高さに維持されるように出来ている。それぞれの組の植付ケース(32)の間に同じようなT字型の側部フロート(55)が配置され、その横軸(56)を前記の横軸(52)と同じ位置に設け、可動枠(17)の横移動で伝動ケース(5)が外側に移動すると、横軸(56)が横軸(52)から離れ、内側に移動すると、この両者が一体的に結合するように構成する。すると、すべてのフロート(54)(55)が単一の操作レバーで上下に移動できる。
【0017】
それぞれの伝動ケース(5)(苗植駆動装置(34)のユニット)ごとにフロートを設け、それぞれを一組として後端部を上下に調節出来るように構成し、その上下レバー(57)を、機体の中心寄りに配置することも出来る(図2)。また、通常の苗植装置と同様に、取量調節レバー(58)の操作で、苗受板(44)を前後方向に調節し、1株分の苗の植付本数が調節できるように構成することが出来る。このとき、それぞれの取量調節レバー(58)を機体の中央寄りに設けると良い(図2)。
【0018】
以上のように、この苗植機は、植付条数に対応した複数の苗植付具(7)を備える苗植装置(2)を走行車体(1)の後側にリンク(3)を介して上下動可能に装着し、苗植装置(2)の苗植付具(7)と苗載台(6)と苗植付具(7)を後部に装着する伝動ケース(5)とをそれぞれ左右中央から右側部分と左側部分とに分けて左右にユニット構成して苗植装置(2)を左右二つに分割可能に設け、前記リンク(3)の後部に中央枠(8)を取付ける一方、苗植装置(2)の左右中央となる分割位置の左右にそれぞれ軸(13)を設け、中央枠(8)に対して前記軸(13)回りにそれぞれ回動可能に側部杆(12)を一対連結し、該左右の側部杆(12)に前記左右の伝動ケース(5)をそれぞれ装着し、左右の側部杆(12)の前記軸(13)回りの回動によって、苗植装置(2)の右側部分と左側部分とを走行車体(1)の後方において横向き姿勢に変更させて苗植装置(2)全体の左右幅が狭くなるように移動可能に構成している。
【0019】
よって、苗植装置(2)の分割位置の左右に設けたそれぞれの軸(13)回りに回動させて苗植装置(2)の右側部分と左側部分とを横向き姿勢に変更させるものであるから、苗植装置(2)の右側部分及び左側部分がそれぞれの左右幅内に配置された軸(13)回りに回動するため、前記右側部分及び左側部分のそれぞれの重心位置に近づけて軸(13)を配置できるので、苗植装置(2)の右側部分と左側部分を適確に支持できる構造としつつ、この回動部分の回動を比較的軽い力で行えて容易に前記右側部分及び左側部分の姿勢変更をすることができ、また前記右側部分及び左側部分の姿勢変更により苗植装置(2)全体の左右幅を狭くする構成であるので、従来のものに比較して苗植装置(2)の左右幅を著しく狭くでき、効率良く運搬や格納ができる。
