Are provided respectively. As shown in FIGS. 5 and 6, the seedling vertical feeding device 101 stretches an endless seedling feeding belt 102 having small protrusions formed on the outer peripheral portion between a driving roller 103 and a driven roller 104, and is driven by a tension spring 105. The rotating shaft 104a of the roller 104 is pulled in the direction in which the seedling feeding belt 102 is stretched. A drive arm 107 is attached via a ratchet mechanism 108 to the roller drive shaft 103a to which the drive roller 103 is attached. Further, as shown in FIG. 8, a seedling vertical feed arm 109 is integrally attached to the seedling vertical feed drive shaft 73, and a roller 110,... Is supported at the tip of the seedling vertical feed arm. . When the seedling stage 80 reaches the end of the left and right stroke, the drive arm 107 comes into contact with the roller 110 and the roller driving shaft 103a is rotated by a predetermined angle, so that the seedling feeding belt 102 operates by a predetermined amount. It has become. When the roller 110 moves away from the drive arm 107, the drive arm 107 returns to the pre-drive posture due to the tension of the torque spring 111. In addition, an operation stop member 113 that is linked to the operation tool 71a for operating the hook clutch 71 via a wire 112 is provided. When the hook clutch 71 is operated to “disengage”, the operation stop member 113 is driven. The seedling feeding belt 102 does not feed by engaging with the roller 104.

各苗載部の上面側下部には、苗が浮き上がるのを防止する苗押え具１１５と、最下段に位置する苗の葉を受けて葉が下方に垂れ下がらないように持ち上げる抵抗棒１１６，…とが設けられている。苗押え具１１５は、仕切壁８１，８１に突設した支柱１１７，１１７に回動自在に支持されており、図５において実線で示す苗押え作用状態と同図において鎖線で示す苗押え非作用状態とに切り替えられるようになっている。 In the lower part on the upper surface side of each seedling mounting part, a seedling presser 115 for preventing the seedling from floating, and a resistance bar 116 for receiving the leaf of the seedling located at the lowest stage and lifting the leaf so that it does not hang downwards,.

この田植機１は、運搬時や格納時に苗植付部４の左右幅を縮小させるための構成が各所に施されている。まず、苗載台８０の左右端部をりたたみむ構成について説明する（図６〜図１０参照）。 This rice transplanter 1 is provided with various configurations for reducing the lateral width of the seedling planting unit 4 during transportation and storage. First, the structure which folds the right-and-left end part of the seedling mounting stand 80 is demonstrated (refer FIGS. 6-10).

左から３番目の苗載部８０−３と４番目の苗載部８０−４を仕切る仕切壁８１−４は、内側の部位８１ａと外側の部位８１ｂとに分割されており、内側の部位８１ａは中央部の苗載部８０−４〜８０〜８と一体に形成され、外側の部位８１ｂは左外側３条の苗載部８０−１，８０−２，８０−３と一体に形成されている。この仕切壁８１−４は、仕切壁８１−９を除く他の仕切壁よりも苗載面に対して高く形成されている。そして、両部位８１ａ，８１ｂの上端部に形成した筒状部１２０ａ，１２０ｂ，…に１本の回動軸１２１を挿通して設け、この回動軸１２１を中心として左外側３条の苗載部８０−１，８０−２，８０−３を上側内向きに反転させ、当該部分を左から４番目乃至６番目の苗載部８０−４，８０−５，８０−６の上に重なり合う状態に折りたたむようにしている。左から５番目乃至７番目の仕切壁８１−５，８１−６，８１−７に設けた支柱１１７，…の頂部には凹状の支柱受け１２２，…が固着されており、左外側３条の苗載部が折りたたまれたとき仕切壁８１−１，８１−２，８１−３に設けた支柱１１７，…の頂部がこの支柱受け１２２，…に係合する。 The partition wall 81-4 that partitions the third seedling mounting part 80-3 and the fourth seedling mounting part 80-4 from the left is divided into an inner part 81a and an outer part 81b, and the inner part 81a. Is integrally formed with the center seedling mounting portions 80-4 to 80-8, and the outer portion 81b is formed integrally with the three left outer seedling mounting portions 80-1, 80-2, 80-3. Yes. This partition wall 81-4 is formed higher than the other partition walls except the partition wall 81-9. Then, a cylindrical shaft 120a, 120b,... Formed on the upper ends of both parts 81a, 81b is provided with a single rotating shaft 121 inserted, and three left outer seedlings are mounted around the rotating shaft 121. The state where the portions 80-1, 80-2, 80-3 are inverted inwardly and the portions overlap the fourth to sixth seedling mounting portions 80-4, 80-5, 80-6 from the left I want to fold it. .. Are attached to the tops of the columns 117,... Provided on the fifth to seventh partition walls 81-5, 81-6, 81-7 from the left. When the seedling mounting part is folded, the tops of the columns 117,... Provided on the partition walls 81-1, 81-2, 81-3 engage with the column receivers 122,.

また、右から２番目の苗載部８０−９と３番目の苗載部８０−８を仕切る仕切壁８１−９は、内側の部位８１ａと外側の部位８１ｂとに分割されており、内側の部位８１ａは中央部の苗載部８０−４〜８０−８と一体に形成され、外側の部位８１ｂは右外側２条の苗載部８０−９，８０−１０と一体に形成されている。この仕切壁８１−９は仕切壁８２−４よりも更に苗載面に対して高く形成されている。そして、両部位８１ａ，８１ｂの上端部に形成した筒状部１２０ａ，１２０ｂ，…に１本の回動軸１２１を挿通して設け、この回動軸１２１を中心として右外側２条の苗載部８０−９，８０−１０を上側内向きに反転させ、当該部分を右から３番目と４番目の苗載部８０−７，８０−８の上に重なり合う状態に折りたたむようにしている。一番左側の仕切壁８１−１の底面に凹状の支柱受け１２２が固着されており、右外側２条の苗載部が折りたたまれたときに一番右側の仕切壁８１−１１に設けた支柱１１７の頂部がこの支柱受け１２２に係合する。また、仕切壁８１−８の設け支柱１１７の頂部と仕切壁８１−１０に設けた支柱１１７の頂部を補助支柱１２３で連結して、苗載部８０−９，８０−１０を支える。 The partition wall 81-9 that divides the second seedling mounting part 80-9 and the third seedling mounting part 80-8 from the right is divided into an inner part 81a and an outer part 81b. The part 81a is formed integrally with the seedling mounting parts 80-4 to 80-8 in the central part, and the outer part 81b is formed integrally with the seedling mounting parts 80-9 and 80-10 of the right outer two stripes. The partition wall 81-9 is formed higher than the partition wall 82-4 with respect to the seedling mounting surface. Then, a single rotating shaft 121 is inserted through the cylindrical portions 120a, 120b,... Formed at the upper ends of the two parts 81a, 81b, and two seedlings on the right outer side are centered on the rotating shaft 121. The portions 80-9 and 80-10 are inverted inwardly, and the portions are folded so as to overlap the third and fourth seedling mounting portions 80-7 and 80-8 from the right. A concave support column 122 is fixed to the bottom surface of the leftmost partition wall 81-1, and the support column provided on the rightmost partition wall 81-11 when the right outer two seedlings are folded. The top of 117 engages with the column support 122. Further, the top of the support column 117 provided on the partition wall 81-8 and the top of the support column 117 provided on the partition wall 81-10 are connected by the auxiliary support column 123 to support the seedling mounting portions 80-9 and 80-10.

なお、前記筒状部の配置に関し、筒状部１２０ａ，１２０ｂは上下３組に分けて配置され、上から１２０ｂ，１２０ａ，１２０ｂ，１２０ａ，１２０ａ，１２０ｂの順に並んでいる。また、上２組の筒状部１２０ａ，１２０ｂ間には隙間がないが、最下部の筒状部１２０ａ，１２０ｂには隙間Ｓが設けられている。これは次の理由による。すなわち、苗受板８３のＬ状本体部８３ｂは側面視で鋭角になっているので、左外側３条の苗載部８０−１，８０−２，８０−３及び右外側２条の苗載部８０−９，８０−１０をそのままの位置では反転させることができず、Ｌ状本体部８３ｂとの干渉を避けるために苗載台の傾斜に沿って隙間Ｓ分だけ押し上げた状態で上記苗載部を反転させるためである。 Regarding the arrangement of the cylindrical portions, the cylindrical portions 120a and 120b are arranged in three upper and lower groups, and are arranged in the order of 120b, 120a, 120b, 120a, 120a, and 120b from the top. Further, there is no gap between the upper two sets of cylindrical portions 120a and 120b, but a gap S is provided in the lowermost cylindrical portions 120a and 120b. This is due to the following reason. That is, since the L-shaped main body part 83b of the seedling receiving plate 83 has an acute angle in a side view, the seedling mounting parts 80-1, 80-2, 80-3 on the left outer three lines and the seedlings on the right outer two lines are placed. The parts 80-9 and 80-10 cannot be reversed in their positions, and the seedlings are pushed up by the gap S along the inclination of the seedling stage in order to avoid interference with the L-shaped body part 83b. This is for inverting the mounting portion.

図９における８２は前記横枠で、この横枠は中央部の苗載部８０−４〜８０−８と左右外側部の苗載部８０−１，８０−２，８０−３（或は８０−９，８０−１０）の境界部近傍で中央部分８２Ａと外側部分８２Ｂに分離している。そして、中央部分８２Ａの左右両端部に前記取付部材８８が固着されていると共に、外側部分８２Ｂの内端部に取付部材８８に対向させて固定部材１２４が固着されている。固定部材１２４には左右に貫通する丸孔１２５が穿設され、また取付部材８８には前記丸孔１２５の延長線上にねじ孔１２６が穿設されている。先端部にねじが切られた固定棒１２７を外側から固定部材１２４の丸孔１２５に挿入し、その先端ねじ部を取付部材８８のねじ孔１２６に螺合させることにより、左右外側部の苗載部８０−１，８０−２，８０−３（或は８０−９，８０−１０）を中央部の苗載部８０−４〜８０−８に固定する。なお、固定棒１２７の適所に小径部１２７ａが形成されており、左右外側部の苗載部を折りたたむに際して固定棒１２７をねじ孔１２６から引き抜くと、この小径部１２７ａにノックピン１２８の先端が係合するため、固定棒１２７がそれ以上抜けないようになっている。小径部１２７ａの外側の壁面はテーパ状になっているので、固定棒１２７を押し込むことはできる。図中の１２９はノックピン１２８を固定棒側に付勢するスプリングである。 In FIG. 9, reference numeral 82 denotes the horizontal frame. The horizontal frame includes the seedling mounting portions 80-4 to 80-8 at the center and the seedling mounting portions 80-1, 80-2 and 80-3 (or 80 −9, 80-10) in the vicinity of the boundary portion 82A and the outer portion 82B. The mounting member 88 is fixed to both left and right end portions of the central portion 82A, and the fixing member 124 is fixed to the inner end portion of the outer portion 82B so as to face the mounting member 88. The fixing member 124 is formed with a round hole 125 penetrating left and right, and the mounting member 88 is formed with a screw hole 126 on an extension line of the round hole 125. A fixing rod 127 threaded at the tip is inserted into the round hole 125 of the fixing member 124 from the outside, and the tip screw is screwed into the screw hole 126 of the mounting member 88, so The parts 80-1, 80-2, 80-3 (or 80-9, 80-10) are fixed to the seedling mounting parts 80-4 to 80-8 in the central part. A small-diameter portion 127a is formed at an appropriate position of the fixing rod 127. When the fixing rod 127 is pulled out from the screw hole 126 when folding the seedling mounting portion on the left and right outer portions, the tip of the knock pin 128 is engaged with the small-diameter portion 127a. Therefore, the fixing rod 127 is prevented from coming out any more. Since the outer wall surface of the small diameter portion 127a is tapered, the fixing rod 127 can be pushed in. 129 in the figure is a spring that urges the knock pin 128 toward the fixed rod.

図１０における１３１は苗載台の裏面上部に設けた横パイプで、この横パイプも中央部の苗載部８０−４〜８０−８と左右外側部の苗載部８０−１，８０−２，８０−３（或は８０−９，８０−１０）の境界部近傍で中央部分１３１Ａと外側部分１３１Ｂに分離している。そして、中央部分１３１Ａの中空部内端側に雄ねじ部材１３２が嵌装されている。先端部にねじ孔１３３が形成された固定棒１３４を外側から横パイプ１３１内に挿入し、そのねじ孔１３３を雄ねじ部材１３２に螺合させることにより、左右外側部の苗載部８０−１，８０−２，８０−３（或は８０−９，８０−１０）を中央部の苗載部８０−４〜８０−８に固定する。この固定棒１３４の抜落ち防止機構は、前記固定棒１２７のそれと同様で、スプリング１３６で付勢されたノックピン１３７を固定棒１３４の小径部１３４ａに係合させるようになっている。 Reference numeral 131 in FIG. 10 denotes a horizontal pipe provided at the upper part of the back surface of the seedling stage. This horizontal pipe is also formed in the center seedling mounting parts 80-4 to 80-8 and the left and right outer seedling mounting parts 80-1 and 80-2. , 80-3 (or 80-9, 80-10) near the boundary portion 131A and the outer portion 131B. A male screw member 132 is fitted on the inner end side of the hollow portion of the central portion 131A. A fixing rod 134 having a screw hole 133 formed at the tip is inserted into the horizontal pipe 131 from the outside, and the screw hole 133 is screwed into the male screw member 132, whereby the seedling mounting parts 80-1 on the left and right outer parts are 80-2, 80-3 (or 80-9, 80-10) is fixed to the seedling mounting part 80-4 to 80-8 in the central part. The mechanism for preventing the fixing bar 134 from dropping is the same as that of the fixing bar 127, and the knock pin 137 urged by the spring 136 is engaged with the small diameter portion 134a of the fixing bar 134.

左右外側部の苗載部を展開した状態では、中央部の苗縦送り装置１０１Ａと左右外側部の苗縦送り装置１０１Ｂが伝動連結されるように構成されている（図６参照）。すなわち、中央部の苗縦送り装置１０１Ａのローラ駆動軸１０３ａＡは、その内端部に駆動アーム１０７がラチェット機構１０８を介して取り付けられていると共に、外端部にクラッチ爪を備えた駆動クラッチ体１４０が一体に取り付けられている。駆動クラッチ体１４０には、外側部のローラ駆動軸１０３ａＢに取り付けた従動クラッチ体１４１が咬み合うようになっている。従動クラッチ体１４１は、外側部のローラ駆動軸１０３ａＢに一体回転するように嵌合し、かつ軸心方向に摺動可能で、スプリング１４２によって軸端側に付勢されている。したがって、両クラッチ体１４０，１４１を連結する際に、双方のクラッチ爪同士が突き合っても、従動クラッチ体１４１が逃げることができるので、両クラッチ体１４０，１４１の位相が合っていなくても無理なく連結すると共に、迅速に咬み合い状態になる。 In the state where the left and right outer side seedling mounting portions are unfolded, the center seedling vertical feeding device 101A and the left and right outer side seedling vertical feeding device 101B are configured to be transmission-coupled (see FIG. 6). In other words, the roller drive shaft 103aA of the center seedling vertical feed device 101A is a drive clutch body having a drive arm 107 attached to its inner end via a ratchet mechanism 108 and a clutch pawl at its outer end. 140 is integrally attached. The drive clutch body 140 is engaged with a driven clutch body 141 attached to the outer roller drive shaft 103aB. The driven clutch body 141 is fitted to the roller drive shaft 103aB on the outer side so as to rotate integrally, is slidable in the axial direction, and is urged toward the shaft end side by a spring 142. Therefore, when the clutch bodies 140 and 141 are connected, the driven clutch body 141 can escape even if both clutch claws collide with each other, so the phases of the clutch bodies 140 and 141 are not in phase. Connected without difficulty and quickly engaged.

苗載台支持フレーム８５は、図５に示すように、ユニット伝動部６２−２，６２−４に基部が固着された縦フレーム８５ａ，８５ａの上部に横フレーム８５ｂを水平に設け、該横フレームの左右端部に回動フレーム８５ｃ，８５ｃを回動自在に設けた構成で、縦フレーム８５ａ，８５ａの上端部に中央部の苗載部８０−４〜８０−８を支持するローラ８６，８６が取り付けられ、また回動フレーム８５ｃ，８５ｃの先端部に左右外側の苗載部８０−１，８０−２，８０−３（或は８０−９，８０−１０）を支持するローラ８６，８６が取り付けられている。 As shown in FIG. 5, the seedling support frame 85 is provided with a horizontal frame 85b horizontally above the vertical frames 85a and 85a whose bases are fixed to the unit transmission portions 62-2 and 62-4. Rotating frames 85c and 85c are rotatably provided at the left and right ends of the rollers, and rollers 86 and 86 for supporting the seedling mounting portions 80-4 to 80-8 in the central portion at the upper ends of the vertical frames 85a and 85a. , And rollers 86 and 86 for supporting the left and right outer seedling mounting portions 80-1, 80-2, and 80-3 (or 80-9 and 80-10) at the distal ends of the rotating frames 85c and 85c. Is attached.

左右外側の苗載部を支持するローラ８６は、図１１に示すごとく、そのローラ軸８６ａが回動フレーム８５ｃのローラ軸孔に軸方向に摺動自在に嵌合しており、ローラ軸８６ａに遊嵌するスプリング８６ｂにて回動フレーム８５ｃから離れる方向に付勢されローラ軸８６ａに挿通した割りピン８６ｃによって抜止めされている。ローラ軸８６ａの端部には、指掛け８６ｄが固着されている。この指掛け８６ｄに指を掛けてローラ軸８６ａを下方に引き下げると、ローラ８６が上部レール８７のコ字状凹部から外れる。 As shown in FIG. 11, the roller 86 supporting the right and left outer seedling mounting portions has a roller shaft 86a fitted in a roller shaft hole of the rotating frame 85c so as to be slidable in the axial direction. The spring 86b that is loosely fitted is urged in a direction away from the rotating frame 85c, and is prevented by a split pin 86c inserted through the roller shaft 86a. A finger hook 86d is fixed to the end of the roller shaft 86a. When the finger is put on the finger hook 86 d and the roller shaft 86 a is pulled downward, the roller 86 is detached from the U-shaped recess of the upper rail 87.

横フレーム８５ｂと回動フレーム８５ｃの連結部は、横フレーム８５ｂ側の軸８５ｄに回動フレーム８５ｃ側の筒部８５ｅが回動自在かつ軸方向に摺動自在に嵌合している。筒部８５ｅには波状のカム８５ｆが一体に形成されており、軸８５ｄに直交させて挿通したピン８５ｇがこのカム８５ｆに接当するようにスプリング８５ｈによって筒部８５ｅが上向きに付勢されている。常時は、カム８５ｆの凹部にピン８５ｇが係合し、回動フレーム８５ｃが左右側方を向く状態で安定するようになっている。その安定状態よりも回動フレーム８５ｃが苗載台側に回動しないようにするストッパ８５ｉがカム８５ｆに固着されている。 The connecting portion between the horizontal frame 85b and the rotating frame 85c is fitted to the shaft 85d on the side of the horizontal frame 85b so that the cylindrical portion 85e on the side of the rotating frame 85c is rotatable and slidable in the axial direction. A wavy cam 85f is formed integrally with the cylinder 85e, and the cylinder 85e is urged upward by a spring 85h so that a pin 85g inserted perpendicularly to the shaft 85d contacts the cam 85f. Yes. Normally, the pin 85g is engaged with the concave portion of the cam 85f, and the rotation frame 85c is stabilized in a state of facing the left and right sides. A stopper 85i is fixed to the cam 85f so that the rotation frame 85c does not rotate to the seedling stage side than the stable state.

更に、前記外側２条部分の苗送りベルト作動停止用ワイヤ１１２の中間部が、回動フレーム８５ｃの適所に固定されている。このため、左右外側の苗載部を支持するローラ８６が上部レール８７のコ字状凹部から外れた状態で苗載台の外側２条部分を折りたたむと、ワイヤ１１２に引かれて回動フレーム８５ｃが後方に回動する。この時、ピン８５ｇが波状のカム８５ｆに沿って摺動するため、回動フレーム８５ｃの回動は滑らかに行われる。 Further, the middle part of the seedling feed belt operation stopping wire 112 of the outer two strips is fixed at an appropriate position of the rotating frame 85c. For this reason, when the roller 86 supporting the right and left outer seedling mounting parts is detached from the U-shaped recesses of the upper rail 87, the outer two strips of the seedling mounting base are folded and pulled by the wire 112, the rotating frame 85c. Pivots backwards. At this time, since the pin 85g slides along the wavy cam 85f, the rotation frame 85c rotates smoothly.

次に、図１２〜１４に基づき、伝動ケース６０の左右端折曲げ部の構造について説明する。第二連結パイプ６４は、植付伝動ケース６２−２（或は６２−４）側の内側パイプ６４Ａと植付伝動ケース６２−１（或は６２−５）側の外側パイプ６４Ｂとからなり、両パイプの接合部の上方に位置する前後方向の回動支点軸１７０を支点にして、内側パイプ６４Ａに対し外側パイプ６４Ｂが上側に回動可能になっている。回動支点軸１７０は、その中央部が外側パイプ６４Ｂの回動支点軸支持部１７１に穿設した回動支点軸挿通孔１７２に挿通され、その前後端部が内側パイプ６４Ａに固着した前後の連結プレート１７４，１７５にそれぞれ設けたベアリング１７６，１７６によって回転自在に支承されている。 Next, based on FIGS. 12-14, the structure of the right-and-left end bending part of the transmission case 60 is demonstrated. The second connection pipe 64 includes an inner pipe 64A on the planting transmission case 62-2 (or 62-4) side and an outer pipe 64B on the planting transmission case 62-1 (or 62-5) side. The outer pipe 64B is pivotable upward with respect to the inner pipe 64A, with the pivot point 170 in the front-rear direction positioned above the joint of both pipes as a fulcrum. The rotation fulcrum shaft 170 is inserted through a rotation fulcrum shaft insertion hole 172 formed at the center of the rotation fulcrum shaft support 171 of the outer pipe 64B, and the front and rear ends thereof are fixed to the inner pipe 64A. It is rotatably supported by bearings 176 and 176 provided on the connecting plates 174 and 175, respectively.

回動支点軸１７０の前後中央部には平面状の面取り部１７０ａが形成されており、回動支点軸支持部１７１の上面側からねじ込んだ回動支点軸固定ボルト１７８の先端部を上記面取り部１７０ａに係合させ、回動支点軸１７０を上下方向にガタつかないように固定している。また、連結プレート１７４，１７５の外面側からねじ込んだベアリング固定ボルト１７９，１７９によって、前記ベアリング１７６，１７６を固定することにより、回動支点軸１７０が左右方向にガタつかないようにしている。 A flat chamfered portion 170a is formed at the front and rear central portion of the rotation fulcrum shaft 170, and the tip end portion of the rotation fulcrum shaft fixing bolt 178 screwed from the upper surface side of the rotation fulcrum shaft support portion 171 is the chamfered portion. The rotating fulcrum shaft 170 is fixed so as not to rattle in the vertical direction. Further, by fixing the bearings 176 and 176 with bearing fixing bolts 179 and 179 screwed from the outer surface side of the connecting plates 174 and 175, the rotation fulcrum shaft 170 is prevented from rattling in the left-right direction.

両パイプ６４ａ，６４ｂの接合部は、内側パイプ６４Ａ側のテーパ状凸部１８３と外側パイプ６４Ｂ側のテーパ状凹部１８４が嵌合する構造になっている。接合部の下方に、ロックナット１８５ａ，１８５ａにて内側パイプ６４Ａに螺着された左右一対の調節ボルト１８５，１８５が設けられており、この調節ボルトの頭部で外側パイプ６４Ｂの内端面下部を受けている。調節ボルト１８５，１８５のねじ込み量を変更することにより、内側パイプ６４Ａに対する外側パイプ６４Ｂの左右及び上下の傾きを調節することができる。 The joint part of both the pipes 64a and 64b has a structure in which the tapered convex part 183 on the inner pipe 64A side and the tapered concave part 184 on the outer pipe 64B side are fitted. A pair of left and right adjustment bolts 185 and 185 screwed to the inner pipe 64A by lock nuts 185a and 185a are provided below the joint, and the lower end of the inner end surface of the outer pipe 64B is attached to the head of the adjustment bolt. is recieving. By changing the screwing amount of the adjusting bolts 185 and 185, the left and right and up and down inclinations of the outer pipe 64B with respect to the inner pipe 64A can be adjusted.

第二連結パイプ６４が真っ直ぐな状態では、内側パイプ６４Ａに基部が左右軸回り回動自在に支持されている固定ハンドル３５１（図１９参照）に固着された固定用プレート１８８に、外側パイプ６４Ｂにロックナット１８９ａにて螺着された固定用ボルト１８９の頭部が当接することにより、内外両パイプ６４Ａ，６４Ｂが離れないように固定する。 In a state where the second connecting pipe 64 is straight, the fixing pipe 188 fixed to the fixing handle 351 (see FIG. 19) whose base is pivotally supported by the inner pipe 64A so as to be rotatable about the left and right axis is attached to the outer pipe 64B. When the head of the fixing bolt 189 screwed by the lock nut 189a comes into contact, the inner and outer pipes 64A and 64B are fixed so as not to be separated.

上記状態から、固定ハンドル３５１を下側に回動させると、第二連結パイプ６４の固定が解除される。その状態で、内側パイプ６４Ａに対し外側パイプ６４Ｂを上側に９０度折り曲げると、外側パイプ６４Ｂに設けられているロックピン１９３の先端部が連結プレート１７４に形成されているロックピン穴１７４ａに嵌り込み、その姿勢で第二連結パイプ６４が固定される。 When the fixed handle 351 is rotated downward from the above state, the second connection pipe 64 is released. In this state, when the outer pipe 64B is bent 90 degrees upward with respect to the inner pipe 64A, the tip of the lock pin 193 provided on the outer pipe 64B is fitted into the lock pin hole 174a formed in the connecting plate 174. The second connecting pipe 64 is fixed in this posture.

サイド植付主軸７０は、第二連結パイプ６４の折曲げ部の位置で内側部７０Ａと外側部７０Ｂに分かれており、内側パイプ６４Ａと外側パイプ６４Ｂが接合する状態では爪クラッチ１９４にて両部７０Ａ，７０Ｂが連結され、第二連結パイプ６４を折り曲げると、爪クラッチ１９４が外れて外側部７０Ｂは外側パイプ６４Ｂと共に回動するようになっている。爪クラッチ１９４は内側部７０Ａ側の爪１９４ａと外側部７０Ｂ側の爪１９４ｂとが一箇所でだけ噛み合う構成であるので、内側部７０Ａと外側部７０Ｂを連結する際に爪クラッチ１９４の噛み合わせを誤り、外側２条の苗植付装置２００−１，２００−２（或は２００−９，２００−１０）の作動の位相がずれることが防止される。 The side planting main shaft 70 is divided into an inner portion 70A and an outer portion 70B at the position of the bent portion of the second connecting pipe 64. When the inner pipe 64A and the outer pipe 64B are joined, both portions are engaged by the claw clutch 194. When 70A and 70B are connected and the second connecting pipe 64 is bent, the claw clutch 194 is released and the outer portion 70B rotates together with the outer pipe 64B. Since the claw clutch 194 is configured such that the claw 194a on the inner side 70A side and the claw 194b on the outer side 70B side are engaged with each other only at one place, the claw clutch 194 is engaged when the inner side 70A and the outer side 70B are connected. It is possible to prevent errors in the phase of operation of the outer two seedling planting devices 200-1 and 200-2 (or 200-9 and 200-10).

図１６はフロート支持軸の分割部の構造を表す図である。フロート支持軸２１１は、センターフロート２１０Ｃ及びミッドフロート２１０Ｍ，２１０Ｍを支持する中央部分２１１Ａと、サイドフロート２１０Ｓ，２１０Ｓを支持する左右端部分２１１Ｂ，２１１Ｂとからなり、両部にそれぞれ固着した断面Ｕ字状の連結具２６０，２６１を互いに係合させてある。連結具２６０，２６１は前後に長く成形されているので、植付深さレバー２１５の操作による中央部分２１１Ａの回動が左右端部分２１１Ｂ，２１１Ｂへ確実に伝達される。また、この構成にすると、連結具２６０，２６１の内側に形成された前後に連通する空間部２６２を通って泥が後方に抜けるため、泥等を咬み込むことによる連結不良が生じない。 FIG. 16 is a diagram illustrating the structure of the split portion of the float support shaft. The float support shaft 211 includes a center portion 211A that supports the center float 210C and the mid floats 210M and 210M, and left and right end portions 211B and 211B that support the side floats 210S and 210S. The connecting members 260 and 261 are engaged with each other. Since the couplers 260 and 261 are formed long in the front-rear direction, the rotation of the central portion 211A by the operation of the planting depth lever 215 is reliably transmitted to the left and right end portions 211B and 211B. In addition, with this configuration, mud flows backward through the space portion 262 that is formed inside the couplers 260 and 261 and communicates with the front and rear, so that poor connection due to biting mud or the like does not occur.

伝動ケース６０の左右端部を上側に回動させて折り曲げると、それに連動して折りたたみ部２１１Ｂ，２１１Ｂも上側に折りたたまれ、また伝動ケース６０の左右端部を本体側に連結すると、それに連動して両部２１１Ａ，２１１Ｂが連結される。このように、フロート支持軸２１１については折りたたみ時及び戻し時に操作を行わなくてもよいので、水田作業機全般の左右幅縮小作業の労力が軽減される。なお、フロート支持軸２１１を折りたたむ際には、植付深さレバー２１５を運搬位置すなわちフロート２１０，…が持ち上がる位置に操作して行う。この時、連結具２６０，２６１が回動支点軸１７０と平行になるようしてあるので、フロート支持軸２１１を折りたたんだときに連結具２６０，２６１が下方に突出せず邪魔にならない。 When the left and right end portions of the transmission case 60 are turned upward and bent, the folding portions 211B and 211B are also folded upward, and when the left and right end portions of the transmission case 60 are connected to the main body side, they are linked. Thus, the two parts 211A and 211B are connected. Thus, since it is not necessary to operate the float support shaft 211 at the time of folding and returning, the labor for reducing the lateral width of the paddy field work machine in general is reduced. When the float support shaft 211 is folded, the planting depth lever 215 is operated to the transport position, that is, the position where the floats 210 are lifted. At this time, since the couplers 260 and 261 are parallel to the rotation fulcrum shaft 170, the couplers 260 and 261 do not protrude downward and do not get in the way when the float support shaft 211 is folded.

（苗受板）
次に、苗受板について説明する。
苗植付部は、ユニット伝動部の要部拡大側面図を図１８に示すように、後ろ下がりに傾斜して苗マットを載せる苗載台８０と、その苗マットの下端を受ける苗受板８３と、この苗受板８３の本体部８３ｂに形成した苗取口９０にその後方から臨んで苗株を圃場に植え込む植付装置２００と、これら苗受板８３および植付装置２００を一体に支持する複数のユニット伝動部６２とからなる多条植付け用の苗植付部４を走行車体２に備え、その苗植付部４の外側端部を収納位置まで跳ね上げるように側方回動可能に構成し、上記苗植付部４の外側端部の苗受板８３は、苗取口９０を形成した本体部８３ｂがその基台部８３ａより下位となる展開姿勢になるまでの角度範囲Ａで、同ユニット伝動部６２に設けた支軸８３ｃについて後方回動可能に屈曲アーム８３ｄにより軸支して構成する。上記苗受板８３の苗取口９０には、必要により、植付装置２００による植付軌跡に沿って下方に延びる苗取ガイド９１、背面ガイド９２を設ける。 (Seedling receiving plate)
Next, the seedling receiving plate will be described.
As shown in FIG. 18, an enlarged side view of the main part of the unit transmission unit is formed by the seedling planting unit, which is inclined to the rear and is placed on a seedling mounting base 80 on which a seedling mat is placed, and a seedling receiving plate 83 that receives the lower end of the seedling mat. And a planting device 200 for planting a seedling in the field facing the seedling inlet 90 formed in the main body 83b of the seedling receiving plate 83 from behind, and the seedling receiving plate 83 and the planting device 200 are integrally supported. The traveling vehicle body 2 is provided with a seedling planting part 4 for multi-row planting comprising a plurality of unit transmission parts 62, and can be rotated laterally so that the outer end of the seedling planting part 4 jumps up to the storage position. The seedling receiving plate 83 at the outer end of the seedling planting portion 4 is configured to have an angle range A until the main body portion 83b in which the seedling opening 90 is formed is in a deployed posture that is lower than the base portion 83a. Thus, the support shaft 83c provided in the unit transmission portion 62 is bent so as to be able to rotate backward. And configure supported by the arm 83d. In the seedling collection port 90 of the seedling receiving plate 83, a seedling collection guide 91 and a back surface guide 92 extending downward along the planting locus by the planting device 200 are provided as necessary.

上記苗植付部４の外側端部のユニット伝動部６２を収納位置まで跳ね上げるように側方回動する際は、苗受板８３の本体部８３ｂが基台部８３ａより低い展開姿勢になるまで同苗受板８３を後方回動することにより、苗受板８３がその本体部８３ｂが隣接配置の苗載台８０等の近接部を回避した姿勢で収納位置まで側方回動されることから、苗受板８３の本体部８３ｂの保護によって植付装置２００との関係維持を確保しつつ、全幅寸法が縮小収納される。また、苗受板８３から下方に延びる苗取ガイド９１、背面ガイド９２は、苗受板８３の後方回動によって傾斜姿勢となり、ユニット伝動部６２を収納位置まで側方回動した際に苗取ガイド９１、背面ガイド９２の外方突出が抑えられるので、外側障害物からの保護を図ることができる。 When the unit transmission portion 62 at the outer end portion of the seedling planting portion 4 is laterally rotated so as to jump up to the storage position, the main body portion 83b of the seedling receiving plate 83 has a lower deployed posture than the base portion 83a. By rotating the seedling receiving plate 83 backward, the seedling receiving plate 83 is rotated laterally to the storage position in a posture in which the main body portion 83b avoids the adjacent portion such as the adjacent seedling mounting base 80. Therefore, the entire width dimension is reduced and stored while securing the relationship with the planting device 200 by protecting the main body 83b of the seedling receiving plate 83. In addition, the seedling collection guide 91 and the back guide 92 that extend downward from the seedling receiving plate 83 are inclined by the rearward rotation of the seedling receiving plate 83, and the seedling collection when the unit transmission portion 62 is rotated sideways to the storage position. Since the outward protrusion of the guide 91 and the back guide 92 is suppressed, protection from outside obstacles can be achieved.

この場合において、上記屈曲アーム８３ｄには長穴８３ｅを形成して支軸８３ｃに遊動軸支することにより、苗取り調節時の苗受板８３の動きに対応することができ、また、回動半径を大きくすることで、株挿具２０２への干渉を小さくすることができる。また、苗受板８３が後方回動した位置でユニット伝動部６２に固定するためのマグネット８３ｆを取付けることによりワンタッチ固定が可能となる。 In this case, the bending arm 83d is formed with a long hole 83e and is supported on the support shaft 83c so as to be able to cope with the movement of the seedling receiving plate 83 when adjusting the seedling collection. By increasing the radius, interference with the stock insert 202 can be reduced. Further, one-touch fixing can be performed by attaching a magnet 83f for fixing the seedling receiving plate 83 to the unit transmission portion 62 at a position where the seedling receiving plate 83 is rotated backward.

前述の固定ハンドル３５１は、その要部拡大側面図を図１９に示すように、その長穴Ｂの範囲による移動状態において深さパイプ３５２をストッパとすることにより、収納位置からの垂れ下がりを防止することができる。 The above-described fixed handle 351 is prevented from drooping from the storage position by using the depth pipe 352 as a stopper in the moving state according to the range of the long hole B as shown in FIG. be able to.

（い草移植適用）
次に、い草苗移植の適用例について説明する。
稲苗より丈の長い“い草”の苗移植に適用する場合は、線引きマーカの支柱３５３と苗送りのアームとの間にスペースがない場合の干渉の問題や、線引きマーカが４５°傾斜苗載台８０に回動・収納させるための傾斜平面内を回動する際に、傾斜が緩くてマーカの跡が付きにくいという問題があることから、苗植付部４の平面図および側面図をそれぞれ図２０、図２１に示すように、線引きマーカの支柱（チューブ）３５３とサイドパイプのチューブ３５４を平面視でクランク状とすることにより、線引きマーカの支柱と苗送りのアーム（リターン）との間にスペースができるのみならず、線引きマーカ傾斜平面を立てることになるので、マーカの跡が付き易く、かつ、収納も容易になる。 (Application for transplanting grass)
Next, application examples of transplanting grass seedlings will be described.
When applied to seedling transplantation of “grass”, which is longer than rice seedlings, there is a problem of interference when there is no space between the support 353 of the drawing marker and the arm for feeding the seedling, and the drawing marker is placed at an angle of 45 °. When rotating in the inclined plane for rotating / storing to the stand 80, there is a problem that the inclination is loose and it is difficult to leave a marker mark. As shown in FIGS. 20 and 21, the drawing marker column (tube) 353 and the side pipe tube 354 are formed in a crank shape in a plan view so that the drawing marker column and the seedling feeding arm (return) are spaced apart. In addition to creating a space, a lined marker inclined plane is set up, so that a marker mark is easily attached and storage is facilitated.

い草のマット苗の植付方法については、株挿しピッチより苗取量を小さくする。詳細には、図２２に示すように、縦ピッチＰ１の株挿し時（ａ）のマット苗が、完成時（ｂ）の縦ピッチＰ２が自重で傾斜方向に縮むことから、欠株を防止するために、株挿しピッチＰ１よりもマット苗が縮んだ分の苗取量を減らした縦ピッチＰ２で植付けを行う。 About planting method of mat seedlings of grass, the amount of seedlings is made smaller than the planting pitch. Specifically, as shown in FIG. 22, the mat seedlings at the time when the vertical pitch P 1 is inserted (a) prevents the shortage because the vertical pitch P 2 at the time of completion (b) shrinks in the inclination direction by its own weight. Therefore, planting is performed at a vertical pitch P2 in which the amount of seedlings collected is reduced by the amount of mat seedlings shrunk from the stock insertion pitch P1.

（苗マット株挿装置）
苗マット作成用の株挿装置３６１において、その平面図を図２３（ａ）に示すように、投入されたい草株が投入カップ３６２から抜け落ちないように、投入者Ｗの場所に、巡回移動する投入カップ３６２…とは別に、本体側からストッパとして、要部拡大斜視図（ｂ）のように、取出口側にスカート３６３を設けることにより、株挿しを確実化することができる。 (Seedling mat stock insertion device)
In the stock insertion device 361 for preparing the seedling mat, as shown in a plan view in FIG. 23 (a), the grass stock to be thrown moves to the place of the thrower W so as not to fall out of the throwing cup 362. In addition to the insertion cups 362..., The stock insertion can be ensured by providing a skirt 363 on the outlet side as a main part enlarged perspective view (b) as a stopper from the main body side.

苗搬送部３７１については、苗箱ガイドの例示平面図を図２４に示すように、い草の苗箱の幅Ｃに合わせて、片側の苗箱ガイド３７２を延長することにより、少ない部品点数で片側に寄せて使用することができ、また、両側の苗箱ガイド３７３，３７３を延長することにより、迅速な組付け作業により両側から狭めて使用することができる。このようにして、播種装置３７４、潅水装置３７５、覆土装置３７６を水稲用とい草用に兼用することができる。 For the seedling transport unit 371, as shown in FIG. 24, an exemplary plan view of the seedling box guide is extended to the seedling box guide 372 on one side in accordance with the width C of the seedling box of the weeds, thereby reducing the number of parts. In addition, by extending the seedling box guides 373 and 373 on both sides, it can be used narrowed from both sides by a quick assembling operation. In this way, the sowing device 374, irrigation device 375, and soil covering device 376 can be used for paddy rice and grass.

土詰装置３８１については、ホッパーの仕切例（ａ）（ｂ）の平面図を図２５に示すよう、い草苗箱Ｄの幅に合わせて、両側の仕切板３８２，３８２を設け、または、片側の仕切板３８３を設けて床土供給部を狭めることにより、土の回収回数を少なくして、い草培土の供給を効率的に行うことができる。 As for the earth filling device 381, as shown in FIG. 25, the plan view of the hopper partition examples (a) and (b) is provided with partition plates 382 and 382 on both sides according to the width of the grass seedling box D, or on one side By providing the partition plate 383 and narrowing the floor soil supply unit, the number of times of soil collection can be reduced and the grass cultivation soil can be supplied efficiently.

い草用移植機については、その側面図を図２６に示すように、苗載台８０の中に苗の根を切る切断刃３９１を設置することにより、植付精度を向上することができる。上記切断刃３９１は、苗載台８０の横移動によって苗がずれないように同苗載台８０の下部に配置し、図例のようにスターホイール式で苗送りと連動させても良いし、また、苗送りとは別途駆動してもよい。 As for the grass transplanter, as shown in a side view of FIG. 26, by installing a cutting blade 391 that cuts the root of the seedling in the seedling mount 80, the planting accuracy can be improved. The cutting blade 391 may be arranged at the bottom of the seedling stage 80 so that the seedling is not displaced by the lateral movement of the seedling stage 80, and may be interlocked with seedling feeding by a star wheel type as shown in the figure, Moreover, you may drive separately from seedling feeding.
