また、昇降ハンドル２５と連結リンク２４の上部と連結部には、繰出し作動スイッチ２９が設けられている。そして、作業者が左右の昇降ハンドル２５を押し下げると、それに伴って苗箱収容部１０が下降して地面に接当して苗箱を繰り出して地面に供給する態勢となるが、苗箱収容部１０が下降して地面に接当した後、更に、作業者が左右の昇降ハンドル２５を押し下げると、連結リンク２４の上部に形成した長孔２４ａの上端部に位置していた昇降ハンドル２５の支持ピン２５ａが長孔２４ａの下端部に移動するまで、左右の昇降ハンドル２５は下動する。この時、連結リンク２４に対して昇降ハンドル２５が下動するので、昇降ハンドル２５に設けた繰出し作動スイッチ２９は連結リンク２４に設けた作動用突起２４ｂによりＯＮ状態になり、バッテリーＢＴにて左右電動モータＭ−Ｌ・Ｍ−Ｒが作動し、各繰出駆動軸２７が駆動されることにより、各棒状体２８が１２０度回転し、苗箱Ｃが１箱圃場に繰出される。この時、作業者が左右の昇降ハンドル２５を押し下げを止めて繰出し作動スイッチ２９がＯＦＦになっても、左右電動モータＭ−Ｌ・Ｍ−Ｒが作動し続けるように（苗箱Ｃの繰出しが終了するまでの２秒間）左右タイマー装置Ｔ−Ｌ・Ｔ−Ｒが作動する。また、各棒状体２８が１２０度回転したことを検出するモータ停止用リミットスイッチＳＷを設けてあり、各棒状体２８が１２０度回転した時に各電動モータＭ−Ｌ・Ｍ−Ｒは停止される構成となっている。
Further, a feed operation switch 29 is provided at the upper portion and the connecting portion of the lifting handle 25 and the connecting link 24. Then, when the operator pushes down the left and right lifting handles 25, the seedling box storage unit 10 is lowered to come into contact with the ground, and the seedling box is fed out and supplied to the ground. When the operator lowers the left and right lifting handles 25 after the lowering 10 comes into contact with the ground, the lifting handle 25 located at the upper end of the long hole 24a formed in the upper part of the connecting link 24 is supported. The left and right lifting handles 25 move downward until the pin 25a moves to the lower end of the long hole 24a. At this time, the lifting handle 25 is moved downward with respect to the connection link 24, so that the feeding operation switch 29 provided on the lifting handle 25 is turned on by the operation projection 24b provided on the connection link 24, and the battery BT When the electric motors ML and MR are operated and the feeding drive shafts 27 are driven, the rods 28 are rotated 120 degrees, and the seedling box C is fed to one box field. At this time, even if the operator stops pushing down the left and right lifting handles 25 and the feeding operation switch 29 is turned OFF, the left and right electric motors ML and MR continue to operate (the seedling box C is fed out). The left and right timer devices T-L and T-R are activated for 2 seconds until completion. Further, a motor stop limit switch SW for detecting that each rod-shaped body 28 has rotated 120 degrees is provided, and when each rod-shaped body 28 has rotated 120 degrees, each electric motor ML-MR is stopped. It has a configuration.
回転繰出具９は、苗箱の左右位置を規制するガイド板３９の下側に位置し、該ガイド板３９よりも苗箱群Ｂ側に張り出す状態で設けられている。そして、ナイロン等の素材で作られた布状体４０が、上端を苗箱収容部１０の外側で且つ回転繰出具９の上方に固定して設けられ、その下部が回転繰出具９と苗箱群Ｂとの間に垂れ掛けられている。回転繰出具９のそれぞれ内側に位置する１本の棒状体２８が苗箱群Ｂの最下段の苗箱Ｃの左右縁部Ｃａに下側から係合することにより、苗箱群Ｂを保持している。この状態で繰出し作動スイッチ２９がＯＮすることにより、回転繰出具９が回転すると、苗箱Ｃの縁部Ｃａに係合していた棒状体２８が縁部Ｃａから外れ、最下段の苗箱Ｃが自重で落下して下方に繰り出される。その際、棒状体２８が回転するのに伴い布状体４０が張った状態となり、棒状体２８が縁部Ｃａの先端に形成されている断面鉤状の補強部Ｃｂから外れやすくなる。苗箱Ｃが下方に繰り出される直前に、次の棒状体２８が新たに最下段になる苗箱Ｃの縁部Ｃａに下側から係合し、苗箱群Ｂを保持する。このように、繰出し作動スイッチ２９がＯＮする度に回転繰出具９が１２０度づつ間欠的に回転することにより、苗箱群Ｂから苗箱Ｃを最下段のものから順に一枚づつ下方に繰り出す。
The rotary feeding tool 9 is located below the guide plate 39 that regulates the left and right position of the seedling box, and is provided in a state of projecting to the seedling box group B side from the guide plate 39. A cloth-like body 40 made of a material such as nylon is provided with the upper end fixed outside the seedling box housing 10 and above the rotary feeding tool 9, and the lower part thereof is the rotary feeding tool 9 and the seedling box. It is hung between the group B. One rod-like body 28 located inside each of the rotary feeding tools 9 is engaged with the left and right edge portions Ca of the lowermost seedling box C of the seedling box group B, thereby holding the seedling box group B. ing. When the feeding operation switch 29 is turned on in this state, when the rotary feeding tool 9 rotates, the rod-like body 28 that has engaged with the edge portion Ca of the seedling box C comes off from the edge portion Ca, and the lowest seedling box C Falls under its own weight and is fed downward. At that time, as the rod-like body 28 rotates, the cloth-like body 40 is in a tensioned state, and the rod-like body 28 is easily detached from the reinforcing portion Cb having a bowl-shaped cross section formed at the tip of the edge portion Ca. Immediately before the seedling box C is drawn downward, the next bar 28 is engaged from the lower side with the edge portion Ca of the seedling box C that becomes the lowest stage, and the seedling box group B is held. Thus, every time the feeding operation switch 29 is turned on, the rotary feeding tool 9 is intermittently rotated by 120 degrees, thereby feeding the seedling boxes C from the seedling box group B downward one by one in order from the lowest stage. .
横移動レール４の左側部分４ａ及び右側部分４ｂの後方には、上に人が載って並べられた苗箱を地面にめり込ませるための踏み板５をそれぞれ設けている。横移動レール４の端部位置には後方へ延びる端部固定吊具４１ａを固着し、横移動レール４の左右両側部分４ａ，４ｂの左右方向略中央位置にはそれぞれ中央固定吊具４２を固着すると共に、走行台車３の後部には機体背面視への字形状の可動吊具４３を前後方向の回動軸４３ａ回りに上下に回動可能に設けている。これらの端部固定吊具４１、中央固定吊具４２及び可動吊具４３からそれぞれの吊下チェーン４４ａを介して踏み板５を取り付け、１枚の踏み板５の前部が計３本の吊下チェーン４４ａにより吊り下げられた構成となっている。また、走行台車３の後方に走行台車３と伴走する苗箱載置用伴走トロッコＨが連結フレームＦにて連結されており、該連結フレームＦに側方に延びる固定吊具４１ｂを固着して設け、吊下スプリング４４ｂを介して踏み板５の後部を吊り下げられた構成となっている（作業者が踏み板５に載った時には、吊下スプリング４４ｂが伸びて、踏み板５は並べられた苗箱Ｃ上面に接当する）。従って、左右踏み板５は、各々前部と後部が吊り下げ支持された構成となっているので、踏み板５の支持が安定すること、及び、横移動レール４の左側部分４ａ及び右側部分４ｂの後方で苗箱載置用伴走トロッコＨよりも前方位置に左右踏み板５を配置したことにより、作業者は左右踏み板５上に載る作業や左右踏み板５上で横移動車６にて地面に苗箱Ｃを並べる作業や苗箱載置用伴走トロッコＨに載置された苗箱Ｃを横移動車６に供給する作業が容易に且つ安全に行なえて作業性が良い。
On the rear side of the left side portion 4a and the right side portion 4b of the laterally moving rail 4, there are respectively provided footboards 5 for sinking seedling boxes on which people are placed on the ground. An end fixed hanger 41a extending rearward is fixed to the end position of the lateral movement rail 4, and a central fixed hanger 42 is fixed to each of the left and right side portions 4a and 4b of the horizontal movement rail 4 at substantially the center positions in the left and right directions. At the same time, a movable hanger 43 shaped like a rear view of the machine body is provided at the rear of the traveling carriage 3 so as to be pivotable up and down around a pivot shaft 43a in the front-rear direction. The tread plate 5 is attached from the end fixed hanger 41, the central fixed hanger 42, and the movable hanger 43 via the respective hung chains 44a, and the front portion of one tread plate 5 is a total of three hung chains. The structure is suspended by 44a. In addition, an accompanying trolley truck H for carrying a seedling box that accompanies the traveling cart 3 is connected to the rear of the traveling cart 3 by a connecting frame F, and a fixed suspension 41b extending laterally is fixed to the connecting frame F. Provided, and the rear part of the tread board 5 is suspended through the suspension spring 44b (when the operator rests on the tread board 5, the suspension spring 44b extends so that the tread board 5 is arranged in a seedling box. C touches the top surface). Accordingly, since the left and right footboards 5 are configured to be supported by hanging the front part and the rear part, respectively, the support of the footboard 5 is stabilized, and the left side part 4a and the right side part 4b of the laterally moving rail 4 are rearward. By arranging the left and right footboards 5 in front of the seedling box mounting trolley H, the operator can place the seedling box C on the ground with the laterally moving vehicle 6 on the left and right footboards 5 or on the left and right footboards 5. The operation of arranging the seedlings and the operation of supplying the seedling box C placed on the accompanying cart H for placing the seedling box to the laterally moving vehicle 6 can be easily and safely performed, and the workability is good.
一方、可動吊具４３は左右の踏み板５に対応して左右に一対設けられ、この左右の可動吊具４３どうしを付勢手段となる下降連動用スプリング４５により繋いでいる。従って、この下降連動用スプリング４５により、左右の可動吊具４３は機体の左右中央側（走行台車３側）で上側へ回動するように付勢され、該可動吊具４３に連結された吊下チェーン４４ａを上側へ引き上げる方向に付勢している。尚、下降連動用スプリング４５は左右いずれの可動吊具４３も回動付勢して左右の可動吊具４３で兼用しているので、部品点数を削減できてコストダウンが図れる。可動吊具４３の中途部には下降連動用ロ−ラ４６を設け、横移動レール４の左右両側部分４ａ，４ｂのレール回動支点軸１２近くには、それぞれ前記下降連動用ロ−ラ４６に当接する下降連動用部材（プレ−ト）４７を横移動レール４に対して外側が上位となるように傾斜姿勢で固着して設けている。
On the other hand, a pair of movable suspensions 43 are provided on the left and right corresponding to the left and right footboards 5, and the left and right movable suspensions 43 are connected to each other by a descent interlocking spring 45 serving as an urging means. Accordingly, the left and right movable suspensions 43 are urged by the descending interlocking spring 45 so as to rotate upward on the left and right center side (traveling carriage 3 side) of the body, and the suspensions connected to the movable suspensions 43 are connected. The lower chain 44a is urged in a direction to pull it upward. In addition, since the descent interlocking spring 45 urges both the left and right movable suspensions 43 to serve as both the left and right movable suspensions 43, the number of parts can be reduced and the cost can be reduced. A lowering interlocking roller 46 is provided in the middle of the movable hanging tool 43, and the lowering interlocking roller 46 is located near the rail rotation fulcrum shaft 12 of the left and right side portions 4 a and 4 b of the laterally moving rail 4. A descent interlocking member (plate) 47 that is in contact with the horizontal movement rail 4 is fixedly provided in an inclined posture so that the outer side is higher.
従って、図に示すように、通常は、下降連動用スプリング４５により、左右の可動吊具４３が内側（走行台車３側）へ回動すると、該可動吊具４３の下降連動用ロ−ラ４６がそれぞれ下降連動用部材４７に当接する状態となり、左右の可動吊具４３の回動付勢力がつり合って該可動吊具４３が左右対称となるように回動し、横移動レール４の左右両側部分４ａ，４ｂが左右対称になるよう共に持ち上げられてその端部のスタンド１４が対地浮上した状態となる。このとき、横移動レール４の左右両側部分４ａ，４ｂの上動で端部固定吊具４１及び中央固定吊具４２が上昇すると共に、可動吊具４３の上側へ回動することにより、踏み板５を吊り下げる３本の吊下チェーン４４ａが共に引き上げられ、踏み板５が上動して対地浮上する構成となっている。一方、左右一方の踏み板５に作業者が載ると、図に示すように、該踏み板５側の可動吊具４３に連結した吊下チェーン４４ａが下方へ引かれて当該可動吊具４３が外側（下側）へ回動し、これに伴って下降連動用ロ−ラ４６が左右外側へ移動するため、横移動レール４の下降連動用部材（プレ−ト）４７における前記下降連動用ロ−ラ４６との当接位置が左右外側に変位し、下降連動用部材（プレ−ト）４７が外上がりに形成されている分、横移動レール４は踏み板５に載った側への下降回動が融通されるため、作業者が該踏み板５に載ることにより横移動レール４は端部固定吊具４１及び中央固定吊具４２に連結した吊下チェーン４４ａで下方へ引かれながら回動してスタンド１４が接地する位置まで下降する。この苗箱並べ状態のとき、横移動レール４の回動により該レ−ル４の左右反対側の部分が上昇して左右反対側の下降連動用部材４７が上昇し、該下降連動用部材４７と左右反対側の下降連動用ロ−ラ４６とが離れる状態となるから、左右反対側の可動吊具４３が下降連動用スプリング４５の付勢により若干内側へ回動するが、下降連動用スプリング４５のスプリング長は通常状態より長くなり、該スプリング４５は付勢力が大きくなって通常状態に復帰するように付勢している。従って、前記左右の可動吊具４３、下降連動用ロ−ラ４６、下降連動用部材４７、吊下チェーン４４ａ及び下降連動用スプリング４５等により、踏み板５を下動させるのに連動して横移動レール４を下降させる下降連動機構を構成している。尚、作業者が踏み板５から離れると、下降連動用スプリング４５の付勢力により下降していた横移動レール４及び踏み板５が上昇して、通常状態に復帰する。尚、踏み板５は、地面に並べられている苗箱の上面に当接する高さまで下降するようになっている。
Therefore, as shown in the figure, normally, when the left and right movable suspensions 43 are rotated inward (toward the traveling carriage 3) by the downward interlocking spring 45, the downward interlocking roller 46 of the movable suspension 43 is provided. Are brought into contact with the descent interlocking member 47, and the rotational urging forces of the left and right movable suspensions 43 are balanced so that the movable suspensions 43 are symmetric. Both side portions 4a and 4b are lifted together so as to be bilaterally symmetric, and the stand 14 at the end thereof is in a state of floating to the ground. At this time, the end fixed hanger 41 and the center fixed hanger 42 are lifted by the upward movement of the left and right side portions 4a and 4b of the laterally moving rail 4, and the tread plate 5 is rotated by rotating to the upper side of the movable hanger 43. The three suspension chains 44a that suspend the suspension are pulled up together, and the tread plate 5 moves upward and floats to the ground. On the other hand, when an operator is placed on one of the left and right footboards 5, as shown in the figure, the suspension chain 44a connected to the movable suspension 43 on the side of the footboard 5 is pulled downward, and the movable suspension 43 is outside ( And the descent interlocking roller 46 moves to the left and right outside. Accordingly, the descent interlocking roller in the descending interlocking member (plate) 47 of the laterally moving rail 4 is moved. The lateral movement rail 4 is pivoted downward to the side where it is placed on the tread plate 5 because the contact position with 46 is displaced to the left and right and the downward interlocking member (plate) 47 is formed so as to rise outward. Since the operator is placed on the tread plate 5, the laterally moving rail 4 is rotated while being pulled downward by a suspension chain 44 a connected to the end fixed suspension 41 and the central fixed suspension 42. 14 is lowered to a position where it contacts the ground. In this seedling box arrangement state, the left and right opposite portions of the rail 4 are lifted by the rotation of the laterally moving rail 4 and the downward interlocking member 47 on the opposite left and right is raised, and the downward interlocking member 47 And the left and right opposite descent interlocking roller 46 are separated from each other, so that the movable hanger 43 on the opposite left and right side is slightly inwardly rotated by the downward interlocking spring 45. The spring length of 45 is longer than the normal state, and the spring 45 is urged so that the urging force is increased and the normal state is restored. Accordingly, the left and right movable suspensions 43, the descent interlocking roller 46, the descent interlocking member 47, the suspension chain 44a, the descending interlocking spring 45, etc., move laterally in conjunction with the downward movement of the tread plate 5. A descent interlocking mechanism for lowering the rail 4 is configured. When the worker leaves the tread board 5, the laterally moving rail 4 and the tread board 5 that have been lowered by the urging force of the descent interlocking spring 45 rise and return to the normal state. In addition, the tread board 5 descend | falls to the height which contact | abuts to the upper surface of the seedling box currently arranged in the ground.
図１０（ａ）及び図１２に基づいて苗箱並べ作業について説明すると、予め地面に根切りネット（図示せず）を敷いておく。そして、踏み板５の上に作業者が載って横移動レール４の左右一方を下降させて（例えば、進行方向で右側を下降させて）苗箱並べ状態にすると共に、作業者は昇降ハンドル２５を把持して昇降ハンドル２５を少し押し下げて下降させた側の横移動レール４の内側から一番目の位置決めゲージ１５ａ−１に横移動車６の位置決めストッパー棒１５ｂが当接する位置まで該横移動車６を昇降ハンドル２５を把持して横移動させる（昇降ハンドル２５を少し押し下げ状態で横移動車６を左右移動させると、位置決めストッパー棒１５ｂが位置決めゲージ１５ａ−１〜４に接当する位置になる。昇降ハンドル２５を押し下げないで横移動車６を左右移動させると、位置決めストッパー棒１５ｂは位置決めゲージ１５ａ−１〜４に接当することがないので、横移動車６を横移動レール４上で自由に左右移動させることができる）。その状態で、作業者が左右の昇降ハンドル２５を押し下げて苗箱収容部１０を下降させて地面に接当させ、続けて左右の昇降ハンドル２５を押し下げると、繰出し作動スイッチ２９がＯＮとなり左右苗箱収容部１０の苗箱群Ｂから最下段の左右１枚づつの苗箱Ｃ（Ｃ１とＣ３）を繰り出して、地面に左右２枚の苗箱Ｃ１・Ｃ３間に１枚の苗箱Ｃ２が並べられる間隔をあけて並べる。また、一度繰出し作動スイッチ２９がＯＮになれば、左右タイマー装置Ｔ−Ｌ・Ｔ−Ｒにより左右電動モータＭ−Ｌ・Ｍ−Ｒが作動し続けるので、その間、作業者は昇降ハンドル２５から手を離して自由に踏み板５により前工程で地面に並べられた苗箱Ｃを押圧することができる。
Referring to FIG. 10 (a) and FIG. 12, the seedling box arrangement work will be described. A root cutting net (not shown) is previously laid on the ground. Then, an operator rests on the tread board 5 and lowers one of the left and right sides of the laterally moving rail 4 (for example, lowers the right side in the traveling direction) to bring the seedling box into a line-up state. From the inner side of the laterally moving rail 4 on the side that has been gripped and pushed down a little to lower it, the laterally moving vehicle 6 reaches the position where the positioning stopper rod 15b of the laterally moving vehicle 6 contacts the first positioning gauge 15a-1. Is moved horizontally by gripping the lifting handle 25 (when the lateral movement vehicle 6 is moved left and right with the lifting handle 25 being pushed down slightly, the positioning stopper rod 15b comes into contact with the positioning gauges 15a-1 to 15a-4. When the laterally moving vehicle 6 is moved left and right without depressing the lifting handle 25, the positioning stopper bar 15b does not contact the positioning gauges 15a-1 to 15a-4. In, it is possible to freely horizontally move the horizontal moving wheel 6 on the horizontal transfer rails 4). In this state, when the operator depresses the left and right lifting handles 25 to lower the seedling box receiving portion 10 to contact the ground, and subsequently presses the left and right lifting handles 25, the feeding operation switch 29 is turned on and the left and right seedlings are turned on. The bottom left and right seedling boxes C (C1 and C3) are fed out from the seedling box group B of the box housing unit 10, and one seedling box C2 is placed between the two right and left seedling boxes C1 and C3 on the ground. Arrange them at intervals. In addition, once the feed operation switch 29 is turned ON, the left and right electric motors ML and MR are continuously operated by the left and right timer devices TL and TR. The seedling boxes C arranged on the ground in the previous step can be pressed by the tread board 5 freely.
地面に苗箱Ｃ（Ｃ１とＣ３）が並べられたら、同様にして作業者は昇降ハンドル２５を把持して昇降ハンドル２５を少し押し下げて下降させた側の横移動レール４の内側から二番目の位置決めゲージ１５ａ−２に横移動車６の位置決めストッパー棒１５ｂが当接する位置まで該横移動車６を昇降ハンドル２５を把持して横移動させる。その状態で、作業者が左右の昇降ハンドル２５を押し下げて苗箱収容部１０を下降させて地面に接当させ、続けて左右の昇降ハンドル２５を押し下げると、繰出し作動スイッチ２９がＯＮとなり左右苗箱収容部１０の苗箱群Ｂから最下段の左右１枚づつの苗箱Ｃ（Ｃ２とＣ４）を繰り出して地面に並べる。この時、前工程で並べた２枚の苗箱Ｃ１・Ｃ３間に１枚の苗箱Ｃ２が並べられ、苗箱Ｃ３の外側に苗箱Ｃ４が並べられる。
When the seedling boxes C (C1 and C3) are arranged on the ground, the operator similarly holds the lifting handle 25 and pushes the lifting handle 25 down slightly to lower the second moving rail 4 from the inside. The lateral movement vehicle 6 is moved laterally by holding the lifting handle 25 to a position where the positioning stopper rod 15b of the lateral movement vehicle 6 contacts the positioning gauge 15a-2. In this state, when the operator depresses the left and right lifting handles 25 to lower the seedling box receiving portion 10 to contact the ground, and subsequently presses the left and right lifting handles 25, the feeding operation switch 29 is turned on and the left and right seedlings are turned on. The seedling boxes C (C2 and C4) of the left and right ones are fed out from the seedling box group B of the box housing portion 10 and arranged on the ground. At this time, one seedling box C2 is arranged between the two seedling boxes C1 and C3 arranged in the previous process, and the seedling box C4 is arranged outside the seedling box C3.
次に、同様にして作業者は昇降ハンドル２５を把持して昇降ハンドル２５を少し押し下げて下降させた側の横移動レール４の内側から三番目の位置決めゲージ１５ａ−３に横移動車６の位置決めストッパー棒１５ｂが当接する位置まで該横移動車６を昇降ハンドル２５を把持して横移動させる。その状態で、作業者が左右の昇降ハンドル２５を押し下げて苗箱収容部１０を下降させて地面に接当させ、続けて左右の昇降ハンドル２５を押し下げると、繰出し作動スイッチ２９がＯＮとなり左右苗箱収容部１０の苗箱群Ｂから最下段の左右１枚づつの苗箱Ｃ（Ｃ５とＣ７）を繰り出して地面に並べる。この時、前工程で並べた苗箱Ｃ４の外側に苗箱Ｃ５が並べられ、苗箱Ｃ７は１枚の苗箱Ｃ６が並べられる間隔をあけて並べられる。
Next, in the same manner, the operator grasps the lifting handle 25 and pushes the lifting handle 25 down slightly to position the laterally moving vehicle 6 on the third positioning gauge 15a-3 from the inner side of the laterally moving rail 4. The lateral movement vehicle 6 is moved laterally by holding the lifting handle 25 to a position where the stopper bar 15b comes into contact. In this state, when the operator depresses the left and right lifting handles 25 to lower the seedling box receiving portion 10 to contact the ground, and subsequently presses the left and right lifting handles 25, the feeding operation switch 29 is turned on and the left and right seedlings are turned on. The seedling boxes C (C5 and C7) of the bottom left and right one by one are drawn out from the seedling box group B of the box housing portion 10 and arranged on the ground. At this time, the seedling box C5 is arranged outside the seedling box C4 arranged in the previous process, and the seedling box C7 is arranged with an interval at which one seedling box C6 is arranged.
更に、同様にして作業者は昇降ハンドル２５を把持して昇降ハンドル２５を少し押し下げて下降させた側の横移動レール４の内側から四番目の位置決めゲージ１５ａ−４に横移動車６の位置決めストッパー棒１５ｂが当接する位置まで該横移動車６を昇降ハンドル２５を把持して横移動させる。その状態で、作業者が左右の昇降ハンドル２５を押し下げて苗箱収容部１０を下降させて地面に接当させ、続けて左右の昇降ハンドル２５を押し下げると、繰出し作動スイッチ２９がＯＮとなり左右苗箱収容部１０の苗箱群Ｂから最下段の左右１枚づつの苗箱Ｃ（Ｃ６とＣ８）を繰り出して地面に並べる。この時、前工程で並べた２枚の苗箱Ｃ５・Ｃ７間に１枚の苗箱Ｃ６が並べられ、苗箱Ｃ７の外側に苗箱Ｃ８が並べられる。
Further, in the same manner, the operator holds the lifting handle 25 and pushes the lifting handle 25 down slightly to move it down to the fourth positioning gauge 15a-4 from the inner side of the laterally moving rail 4. The lateral movement vehicle 6 is moved laterally by holding the lifting handle 25 to a position where the bar 15b comes into contact. In this state, when the operator depresses the left and right lifting handles 25 to lower the seedling box receiving portion 10 to contact the ground, and subsequently presses the left and right lifting handles 25, the feeding operation switch 29 is turned on and the left and right seedlings are turned on. The seedling boxes C (C6 and C8) of the bottom left and right one by one are drawn out from the seedling box group B of the box housing portion 10 and arranged on the ground. At this time, one seedling box C6 is arranged between the two seedling boxes C5 and C7 arranged in the previous process, and the seedling box C8 is arranged outside the seedling box C7.
尚、このように走行軌道２の左右一側に８枚の苗箱Ｃを並べる間、作業者は踏み板５上を横移動しながら作業を行うので、踏み板５により作業者の体重をかけて前行程で並べた横一列の計８枚の苗箱Ｃを上方から略均等に押圧することができる。同様に、走行軌道２の左右他側にも横一列に８枚の苗箱Ｃを並べ、走行軌道２部分の地面を苗箱Ｃを並べずに空けて後の育苗管理をするために通路を作り、該通路を挟んで横一列に計８枚づつの苗箱Ｃを並べる。尚、横一列に苗箱Ｃを並べるとき、走行台車３の走行ブレ−キペダル１１を制動状態に固定して機体が前進しないようにするとよい。
While the eight seedling boxes C are arranged on the left and right sides of the traveling track 2 in this way, the worker performs the work while moving laterally on the tread plate 5, so that the weight of the operator is put on the tread plate 5 before A total of eight seedling boxes C in a horizontal row arranged in the process can be pressed substantially evenly from above. Similarly, eight seedling boxes C are arranged in a horizontal row on the left and right sides of the traveling track 2, and a passage is provided to manage the seedling management after leaving the seedling box C on the ground of the traveling track 2 portion without arranging the seedling boxes C. A total of 8 seedling boxes C are arranged in a horizontal row across the passage. In addition, when arranging the seedling boxes C in a horizontal row, the traveling brake pedal 11 of the traveling carriage 3 is preferably fixed in a braking state so that the aircraft does not move forward.
左右方向の計８枚づつの苗箱Ｃの並べ作業が完了したならば、作業者は左右の踏み板５から離れて走行台車３の後方に位置し、横移動レール４の左右両側部分を上昇させて、横移動車４を走行台車３の上方となる横移動レール４の左右中央位置へ移動させ、横移動レール４が次行程で苗箱Ｃを並べる位置に到達するまで（苗箱Ｃの長手方向の長さ分）作業者が横移動車６の昇降ハンドル２５を押して走行台車３を走行軌道２に沿って前進させる。尚、走行台車３が惰性により所望の位置を越える位置まで前進しそうなときは、適宜走行ブレ−キペダル１１を踏み込んで走行台車３に走行制動をかける。以下、前述と同様に、順次踏み板５の上に作業者が載って横一列に苗箱Ｃを並べていき、走行軌道２の左右両側に苗箱を敷き詰めるように並べていく。
When the arrangement of eight seedling boxes C in the left-right direction is completed, the operator moves away from the left and right footboards 5 and is positioned behind the traveling carriage 3 and raises the left and right side portions of the laterally moving rail 4. Then, the laterally moving vehicle 4 is moved to the left and right center position of the laterally moving rail 4 above the traveling carriage 3 until the laterally moving rail 4 reaches a position where the seedling boxes C are arranged in the next stroke (the length of the seedling box C). The length of the direction) The operator pushes the lifting handle 25 of the laterally moving vehicle 6 to advance the traveling carriage 3 along the traveling track 2. When the traveling carriage 3 is likely to move forward to a position exceeding a desired position due to inertia, the traveling brake pedal 11 is appropriately depressed to apply traveling braking to the traveling carriage 3. In the same manner as described above, an operator is sequentially placed on the step board 5 and the seedling boxes C are arranged in a horizontal row, and the seedling boxes are arranged on both the left and right sides of the traveling track 2.
尚、左右の踏み板５の前後方向の長さは、苗箱Ｃの長手方向の長さの１．５倍にしておくと、苗箱並べ作業時に左右の踏み板５は１枚と半枚分の苗箱上に置かれるようになるので、適切な苗箱の地面への押付け作業が行なえて、育苗時の苗の育成が良好となり、優れた苗を得ることができる。
If the length of the left and right footboards 5 in the front-rear direction is 1.5 times the length of the seedling box C in the longitudinal direction, the left and right footboards 5 are equivalent to one and a half when the seedling boxes are arranged. Since it comes to be placed on the seedling box, it is possible to perform an appropriate pressing operation of the seedling box to the ground, and the seedlings at the time of seedling can be cultivated well and excellent seedlings can be obtained.
図１１は、制御装置Ｓの回路図を示すが、ＭＳはメインスイッチで苗箱並べ機の駆動系の全てを停止させるものである。Ｂ−Ｌ・Ｂ−Ｒは左右ブザーであって、各々左右電動モータＭ−Ｌ・Ｍ−Ｒが作動しているときに報知音を出すようになっている。ＰＬはパイロットランプであって、メインスイッチＭＳをＯＮにしている時に点灯する。そして、ＳＴ−Ｌ・ＳＴ−Ｒは左右起動停止スイッチであって、各々左右の昇降ハンドル２５の把持部下方位置に設けられており、左起動停止スイッチＳＴ−Ｌを操作してＯＦＦにすると、左電動モータＭ−Ｌの作動がしなくなり、左苗箱収容部１０からの苗箱並べが停止される。また、右起動停止スイッチＳＴ−Ｒを操作してＯＦＦにすると、右電動モータＭ−Ｒの作動がしなくなり、右苗箱収容部１０からの苗箱並べが停止される。
FIG. 11 shows a circuit diagram of the control device S. The MS is a main switch for stopping all the drive systems of the seedling box arranging machine. B-L and B-R are left and right buzzers, respectively, which emit a notification sound when the left and right electric motors ML and MR are operating. PL is a pilot lamp which lights up when the main switch MS is turned on. ST-L and ST-R are left and right start / stop switches, which are respectively provided below the grips of the left and right lifting handles 25. When the left start / stop switch ST-L is operated and turned OFF, The operation of the left electric motor ML is stopped, and seedling box arrangement from the left seedling box housing portion 10 is stopped. Further, when the right start / stop switch ST-R is operated to be turned OFF, the right electric motor MR is not operated, and the seedling box arrangement from the right seedling box housing portion 10 is stopped.

In this state, when the operator depresses the left and right lifting handles 25 to lower the seedling box receiving portion 10 to contact the ground, and subsequently presses the left and right lifting handles 25, the feeding operation switch 29 is turned on and the left and right seedlings are turned on. The seedling boxes C (C2 and C4) of the left and right ones are fed out from the seedling box group B of the box housing portion 10 and arranged on the ground. At this time, one seedling box C2 is arranged between the two seedling boxes C1 and C3 arranged in the previous process, and the seedling box C4 is arranged outside the seedling box C3.
次に、同様にして作業者は昇降ハンドル２５を把持して昇降ハンドル２５を少し押し下げて下降させた側の横移動レール４の内側から三番目の位置決めゲージ１５ａ−３に横移動車６の位置決めストッパー棒１５ｂが当接する位置まで該横移動車６を昇降ハンドル２５を把持して横移動させる。その状態で、作業者が左起動停止スイッチＳＴ−Ｌを操作してＯＦＦにして、左右の昇降ハンドル２５を押し下げて苗箱収容部１０を下降させて地面に接当させ、続けて左右の昇降ハンドル２５を押し下げると、繰出し作動スイッチ２９がＯＮとなり右苗箱収容部１０の苗箱群Ｂからのみ最下段の右１枚の苗箱Ｃ（Ｃ５）を繰り出して地面に並べる。この時、苗箱Ｃ５は、前工程で並べた苗箱Ｃ４の外側方に並べられる。
Next, in the same manner, the operator grasps the lifting handle 25 and pushes the lifting handle 25 down slightly to position the laterally moving vehicle 6 on the third positioning gauge 15a-3 from the inner side of the laterally moving rail 4. The lateral movement vehicle 6 is moved laterally by holding the lifting handle 25 to a position where the stopper bar 15b comes into contact. In this state, the operator operates the left start / stop switch ST-L to turn it OFF, pushes down the left and right lifting handles 25 to lower the seedling box housing portion 10 to contact the ground, and then lifts left and right. When the handle 25 is pushed down, the feeding operation switch 29 is turned ON, and the lowermost right seedling box C (C5) is fed out only from the seedling box group B of the right seedling box housing portion 10 and arranged on the ground. At this time, the seedling box C5 is arranged outside the seedling box C4 arranged in the previous step.
更に、同様にして作業者は昇降ハンドル２５を把持して昇降ハンドル２５を少し押し下げて下降させた側の横移動レール４の内側から四番目の位置決めゲージ１５ａ−４に横移動車６の位置決めストッパー棒１５ｂが当接する位置まで該横移動車６を昇降ハンドル２５を把持して横移動させる。その状態で、作業者が左起動停止スイッチＳＴ−Ｌを操作してＯＦＦにして、左右の昇降ハンドル２５を押し下げて苗箱収容部１０を下降させて地面に接当させ、続けて左右の昇降ハンドル２５を押し下げると、繰出し作動スイッチ２９がＯＮとなり右苗箱収容部１０の苗箱群Ｂからのみ最下段の右１枚の苗箱Ｃ（Ｃ６）を繰り出して地面に並べる。この時、苗箱Ｃ６は、前工程で並べた苗箱Ｃ５の外側方に並べられる。
Further, in the same manner, the operator holds the lifting handle 25 and pushes the lifting handle 25 down slightly to move it down to the fourth positioning gauge 15a-4 from the inner side of the laterally moving rail 4. The lateral movement vehicle 6 is moved laterally by holding the lifting handle 25 to a position where the bar 15b comes into contact. In this state, the operator operates the left start / stop switch ST-L to turn it OFF, pushes down the left and right lifting handles 25 to lower the seedling box housing portion 10 to contact the ground, and then lifts left and right. When the handle 25 is pushed down, the feeding operation switch 29 is turned ON, and the lowermost right seedling box C (C6) is fed out only from the seedling box group B of the right seedling box housing portion 10 and arranged on the ground. At this time, the seedling box C6 is arranged on the outer side of the seedling box C5 arranged in the previous step.
そして、同様にして走行台車３の左側にも６枚の苗箱Ｃを並べれば、走行台車３の左右両側に６枚づつ苗箱Ｃを並べることができる。
以上により、この苗箱並べ機１は、縦方向に走行させる走行車輪７を備えた機体に横移動レール４を昇降可能に設け、該レール４上に複数の苗箱Ｃを保持して収容する苗箱収容部１０を備える横移動車６を設け、地面に並べた苗箱Ｃを上方から押圧するための踏み板５を下動させるのに連動して前記レール４を下降させる下降連動機構を設けている。従って、作業者が踏み板５に載って該踏み板５を下動させると、下降連動機構により横移動レール４が下降する。そして、該レール４に沿って横移動車６を横移動させながら横一列に苗箱Ｃを並べて作業者が踏み板５から離れることにより、該踏み板５を上動させると共に横移動レール４を上昇させることができる。そして、横移動レール４を上昇させた状態で、順次走行台車３により縦方向へ苗箱１枚分の距離だけ走行し、再度作業者が踏み板５に載って該踏み板５を下動させて横移動レール４を下降させ、次列の苗箱Ｃを並べながら前行程で並べた苗箱Ｃを上方から押圧し、順次苗箱Ｃを地面に並べることができる。
Similarly, if six seedling boxes C are arranged on the left side of the traveling carriage 3, six seedling boxes C can be arranged on both the left and right sides of the traveling carriage 3.
As described above, the seedling box arranging machine 1 is provided with the laterally moving rail 4 so as to be movable up and down on the machine body including the traveling wheels 7 that run in the vertical direction, and holds and stores the plurality of seedling boxes C on the rails 4. A laterally moving vehicle 6 having a seedling box accommodating portion 10 is provided, and a descending interlocking mechanism is provided for lowering the rail 4 in conjunction with the downward movement of the tread plate 5 for pressing the seedling boxes C arranged on the ground from above. ing. Accordingly, when the worker puts on the foot board 5 and moves the foot board 5 downward, the lateral movement rail 4 is lowered by the lowering interlock mechanism. Then, the lateral moving vehicle 6 is moved laterally along the rail 4 and the seedling boxes C are arranged in a horizontal row so that the operator moves away from the foot plate 5 to move the foot plate 5 upward and raise the lateral rail 4. be able to. Then, with the laterally moving rail 4 raised, the vehicle is sequentially driven by the traveling carriage 3 in the vertical direction for a distance of one seedling box, and the operator rests on the tread board 5 again to move the tread board 5 down and move sideways. The moving rail 4 is lowered, the seedling boxes C arranged in the previous process are pressed from above while arranging the seedling boxes C in the next row, and the seedling boxes C can be sequentially arranged on the ground.
