Description

【0001】
【産業上の利用分野】
この発明は、野菜の苗を移植する苗植機に有効に用いられるものである。
【0002】
【従来の技術】
従来、一株毎に育苗された苗を苗取り位置に向けて間欠的に送る苗載台を備え、苗載台上の苗の端から一株分の苗を苗取り位置で欠き取り圃場に移植する構成の移植機がある。
【0003】
苗植機が苗を移植しながら畝の終端に来ると、周知のように、機体を高くしたのち、ハンドルを押し下げて機体を後側の動輪の回りに回動して後下りに傾斜にすることで前側の転輪を上昇させて、苗植機をUターンさせる。
【0004】
【発明が解決しようとする課題】
本発明は、前側の転輪で畝を崩すことなく、苗植機をUターンさせることができるようにすることを課題とする。
【0005】
【課題を解決するための手段】
この発明は、上記の課題を解決するため前側の転輪22,22と、後側の動輪7,7とで支持した苗移植機において、機体の前後方向の傾斜を検出する角度センサ24を設け、機体が設定角度以上に後下がりになったことを前記角度センサ24が検出すると、前記転輪22,22が上昇するように制御する構成としたことを特徴とする苗植機とした。
【0006】
【作用】
それぞれ一対の動輪7,7と転輪22,22で支持された苗植機が苗を移植しながら畝Aの終端に来ると、周知のように、油圧シリンダでチェンケース6,6を反時計方向に回動させて機体を高くする。そののち、ハンドル18,18を押し下げると、機体が動輪7,7の回りに回動して後下りに傾斜する。そして、その傾斜角が設定角度、又はそれ以上になったことを角度センサ24が検出すると、転輪22,22が上昇してその下端が畝Aの上面より自動的高くなる。Uターンが終了すると、ハンドル18,18を持ち上げて機体を元の角度に戻し、動輪7,7を上げる。すると、転輪22,22も下って機体がこれらで支持される。
【0007】
【効果】
以上のように、この発明によると、転輪22,22で畝Aを崩すことなく、苗植機をUターンさせることができる。
【0008】
【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、主歯車箱1の前後にエンジン2と主管3が固定され、主管3の後端に固定された植付歯車箱4から植付フレーム5が斜後上に伸びている。後下りに傾斜した一対のチェンケース6,6の上端が主歯車箱1の両横に揺動自在に取付けられ、畝Aの両横の谷間B,B内を通る一対の動輪7,7がそれぞれの下端部に設けられ、チェンケース6,6揺動で動輪7,7が上下すると、主歯車箱1が畝Aの上面から逆方向に上下するように出来ている。このベルト9は、苗載台10が横端にきたときに駆動される。
【0009】
後向に開いた苗取口8a(図3)を有する苗受板8が植付フレーム5の前部に横向に固定されている。底面がベルト9で構成された苗載台10が苗受板8の前に前上りに配置され、欠ぎ取られた後端の底がこの苗受板8に乗ってエンジン2の動力で左右に往復駆動されるように出来ている。このベルト9は、苗載台10が横端にきたときに駆動される。
【0010】
長円形の第1旋回ケース11がその一端を中心に回転するように植付フレーム5に設けられ、長円形の第2旋回ケース12の一端が第1旋回ケース11の他端を中心に旋回するように設けられ、苗植ケース13が第2旋回ケース12の他端に設けられている。そして、苗植ケース13は、第1旋回ケース11および第2旋回ケース12が旋回するとき、その中の歯車群で同じ姿勢を保って旋回するようになっている。左右に一対の板で構成された苗植具14が苗植ケース13に下向に取付けられ、その先端が上下に長い閉ル−プ軌道Cで旋回する。なお、上記の旋回中、下降行程において苗植具14の先端が苗取口8aを通過し、その直前において左右の板が閉じ、下端において畝Aに突入して開くように構成されている。
【0011】
左右一対の填圧輪15,15が閉ル−プ軌道Cの後に配置されて、その両横で畝Aの上面を軽く填圧するようになっている。ハンドルポスト16が植付フレーム5の途中から斜後上に伸び、その上端にパネル17と2又のハンドル18,18が設けられている。支杆19が主歯車箱1からエンジン2の下腹部を通って前に伸び、その先端に横軸20が回動自在に設けられている。一対の支脚21,21が横軸20の両横から斜後下に伸び、左右の谷B,Bに位置する転輪22,22がそれぞれの下端に取付けられている。電動シリンダ23の後端が支杆19に取付けられ、これから前に突出したロッド23aの先端が横軸20から上に伸びたアーム20aに接続している。前後方向の傾斜を検出する角度センサ24(重錘で作動するポテンショメータで可)が主管3に取付けられている。角度が設定できるダイヤル25がパネル17に設けられている。そして、主管3が後下りに傾斜してその傾斜がダイヤル25で設定した角度、又はそれ以上になると、電動シリンダ23がロッド23aを前方に突出し、支脚21,21が反時計方向に回って転輪22,22が上昇し、その状態からダイヤル25で設定した角度以下に戻ると、ロッド23aが電動シリンダ23内に引き戻されて転輪22,22が下降するように、これらが制御装置26に接続されている(図2)。
【0012】
すなわち、それぞれ一対の動輪7,7と転輪22,22で支持された苗植機が苗を移植しながら畝Aの終端に来ると、周知のように、油圧シリンダ(図示していない)でチェンケース6,6を反時計方向に回動させて機体を高くする。そののち、ハンドル18,18を押し下げると、機体が動輪7,7の回りに回動して後下りに傾斜する。そして、その傾斜角がダイヤル25で設定した角度、又はそれ以上になると、転輪22,22が上昇してその下端が畝Aの上面より自動的高くなる。そのため、この転輪22,22で畝Aを崩すことなく、苗植機をUターンさせることができる。Uターンが終了すると、ハンドル18,18を持ち上げて機体を元の角度に戻し、動輪7,7を上げる。すると、転輪22,22も下って機体がこれらで支持される。
【0013】
なお、転輪22,22の上記の上昇に連動して填圧輪15,15が上昇するように構成すると、Uタ−ンがさらに容易に行われる。すなわち、横軸33が主管3の後の下腹部に回動自在に取り付けられている。填圧輪15,15が設けられた支杆34,34の先端が横軸33の両横に固定され、その後端に縦杆35が摺動自在に差し込まれ、ばね36で押し下げられている。そして、横軸33と一体のア−ム33aと前記のア−ム20aがワイヤ−37やリンクなどで連結されている。そのため、ロッド23aが電動シリンダ23から突出して転輪22,22が上昇するとき、ワイヤ−37が支杆34,34を反時計方向に引き回し、填圧輪15,15が上昇する。
【0014】
苗載台10上には、つぎの集団苗が載せられる。図5のように、紙で出来た台形のポット27a,27a……が下縁で前後左右に連なってポットシート27となっている。その2枚が苗箱28内に並べて入れられる。それぞれのポット27a,27a……内に、床土とキャベツやレタスなどの種子を入れ、各ポット27a,27a間に目土を施す。これに潅水し、数日が経過するとそれぞれの孔27b,27b……から芽が出て苗が育つ。これが適期になると、集団苗として苗箱28から取出し、前後方向を長くして後端が苗受板8上に来るように苗載台10に載せる。
【0015】
苗載台10の後部に、図3および図4に示すつれ出し防止体29が設けられている。集団苗は、後から見ると、ポット27a,27a……が前後方向に重なって、苗30,30……が横並びの複数の条になっている。薄板を縦向にして作った複数のつれ出し防止体29,29……が上記の集団苗の最後部の条間に配置されている。これらのつれ出し防止体29,29……の上縁29a,29a……は最も後の列のポット27a,27a……の前部のやや上から後上りに傾斜し、それぞれの上端が苗載台10の前壁10aに固定されている。また、下縁31a,31a……が左右の目土に接触する横ずれ防止体31,31……がそれぞれの(又は、所定の数を隔てて)つれ出し防止体29,29……の先端から前に伸びている。なお、前壁10aから横並びの複数の線杆32,32……が垂れ下り、集団苗が苗載台10から後に飛び出すのを阻止している。そのため、苗30の葉が横の苗30の葉とからんでいるとき、その苗30,30がベルト9で苗受板8上に送り出された時点でつれ出し防止体29がからんだ葉の間に、それぞれの床土を持ち上げないように、ゆるやかに入り込み、1つの苗30が苗植具14で引き下げられるときにこのつれ出し防止体29がその葉のからみつきをときほぐす。

A seedling mounting base 10 having a bottom surface constituted by a belt 9 is arranged in front of the seedling receiving plate 8, and the bottom of the rear end, which is cut off, rides on the seedling receiving plate 8 and is powered by the power of the engine 2. It can be driven back and forth. The belt 9 is driven when the seedling stage 10 comes to the lateral end.
[0010]
An oval first turning case 11 is provided on the planting frame 5 so as to rotate around one end thereof, and one end of the oval second turning case 12 turns around the other end of the first turning case 11. The seedling planting case 13 is provided at the other end of the second turning case 12. When the first turning case 11 and the second turning case 12 are turned, the seedling case 13 is turned while maintaining the same posture with the gear group therein. A seedling planting tool 14 composed of a pair of plates on the left and right is attached to the seedling planting case 13 downward, and the tip of the seedling planting tool 14 is swung on a closed loop trajectory C that is long vertically. During the above-mentioned turning, the tip of the seedling planter 14 passes through the seedling outlet 8a in the downward stroke, and the right and left plates are closed immediately before that, and the bottom end enters the ridge A and opens.
[0011]
A pair of left and right filling wheels 15 and 15 are disposed after the closed loop track C, and lightly press the upper surface of the heel A on both sides. A handle post 16 extends obliquely upward from the middle of the planting frame 5, and a panel 17 and two handles 18, 18 are provided at the upper end thereof. A support rod 19 extends forward from the main gear box 1 through the lower abdomen of the engine 2, and a horizontal shaft 20 is rotatably provided at the tip thereof. A pair of support legs 21, 21 extend obliquely downward from both sides of the horizontal shaft 20, and rolling wheels 22, 22 positioned in the left and right troughs B, B are attached to the lower ends of the two. The rear end of the electric cylinder 23 is attached to the support rod 19, and the tip of the rod 23a protruding forward from this is connected to the arm 20a extending upward from the horizontal shaft 20. An angle sensor 24 (possible with a potentiometer operated by a weight) for detecting the inclination in the front-rear direction is attached to the main pipe 3. A dial 25 capable of setting an angle is provided on the panel 17. When the main pipe 3 inclines backward and the inclination reaches an angle set by the dial 25 or more, the electric cylinder 23 protrudes forward from the rod 23a and the support legs 21 and 21 rotate counterclockwise. When the wheels 22 and 22 are lifted and returned to the angle set by the dial 25 or less from that state, the rod 23a is pulled back into the electric cylinder 23, and these are transferred to the control device 26 so that the wheels 22 and 22 are lowered. Connected (FIG. 2).
[0012]
That is, when the seedling transplanter supported by the pair of moving wheels 7 and 7 and the rollers 22 and 22 comes to the end of the heel A while transplanting seedlings, as is well known, a hydraulic cylinder (not shown) is used. The chain cases 6 and 6 are rotated counterclockwise to raise the machine body. After that, when the handles 18 and 18 are pushed down, the airframe turns around the driving wheels 7 and 7 and tilts backward. Then, when the inclination angle becomes an angle set by the dial 25 or more, the rollers 22 and 22 are raised and the lower ends thereof are automatically higher than the upper surface of the bag A. Therefore, it is possible to make a U-turn the seedling transplanter without breaking the ridge A with the rollers 22 and 22. When the U-turn ends, the handles 18 and 18 are lifted to return the aircraft to the original angle, and the driving wheels 7 and 7 are raised. Then, the wheels 22 and 22 are also lowered and the airframe is supported by these.
[0013]
In addition, if it comprises so that the filling wheels 15 and 15 may raise in conjunction with said raise of the rolling wheels 22 and 22, U-turn is performed more easily. That is, the horizontal shaft 33 is rotatably attached to the lower abdomen of the main pipe 3.
