本発明は、鉢苗載置部から引き出された連続鉢苗を圃場に移植する連続鉢苗移植機、及び連続鉢苗移植機を用いた作物の生産方法に関する。 TECHNICAL FIELD The present invention relates to a continuous potted seedling transplanter for transplanting continuous potted seedlings pulled out from a potted seedling placing section into a field, and a crop production method using the continuous potted seedling transplanter.

特許文献1には、3つの育苗箱を並列に載置可能な上段載置部及び下段載置部を備えた連続鉢苗移植機が開示されている。この特許文献1に記載された連続鉢苗移植機は、上段載置部の、1枚目の育苗箱分の連続鉢苗、中間の育苗箱分の連続鉢苗、及び3枚目の育苗箱分の連続鉢苗を順次移植して畝の一往路分の植付けを行い、連続鉢苗移植機を反転させた後、下段載置部の、1枚目の育苗箱分の連続鉢苗、中間の育苗箱分の連続鉢苗、及び3枚目の育苗箱分の連続鉢苗を順次移植して復路の移植を行うものである。 Patent Literature 1 discloses a continuous potted seedling transplanter provided with an upper stage mounting section and a lower stage mounting section on which three seedling boxes can be placed in parallel. The continuous potted seedling transplanting machine described in this patent document 1 includes the continuous potted seedlings for the first seedling box, the continuous potted seedlings for the intermediate seedling box, and the third seedling box on the upper stage. After successively transplanting the continuous potted seedlings for one round of ridges, turning the continuous potted seedling transplanter over, the continuous potted seedlings for the first seedling box on the lower stage, the middle Then, the potted seedlings for the first nursery box and the third potted seedlings for the third nursery box are transplanted in sequence, and the return trip is performed.

また、特許文献2には、鉢苗載置部を前後に延長して、2つの育苗箱を直列に載置した連続鉢苗移植機が開示されている。この特許文献2に記載された連続鉢苗移植機では、上側の育苗箱内の連続鉢苗の先端と下側の育苗箱内の連続鉢苗の末端とをステープルで接合することにより、2冊分の連続鉢苗を、移植機を停止させずに移植することができる。 Further, Patent Document 2 discloses a continuous potted seedling transplanter in which two seedling boxes are mounted in series by extending the potted seedling placing portion back and forth. In the continuous potted seedling transplanter described in Patent Document 2, the tip of the continuous potted seedlings in the upper seedling box and the end of the continuous potted seedlings in the lower seedling box are joined with staples to separate two volumes. of consecutive potted seedlings can be transplanted without stopping the transplanter.

登録実用新案第3016320号公報Registered Utility Model No. 3016320 特開平9-271219号公報JP-A-9-271219

特許文献1に記載された連続鉢苗移植機では、一冊分の連続鉢苗の植付けが終わると、次の分の連続鉢苗を誘導路まで引き出す必要がある。移植機を停止させずに上段載置部の連続鉢苗を移植するには、1枚目の育苗箱分の連続鉢苗の末端と、中間の育苗箱分の連続鉢苗の先端と、をステープル等で接合する必要がある。この場合、中間の育苗箱内の連続鉢苗の先端を、育苗箱を縦断させて1枚目の育苗箱分の連続鉢苗の末端まで引き出すが、引き出した連続鉢苗が育苗箱内の苗に乗り上げて苗が損傷するおそれがある。また、引き出した連続鉢苗の移動距離が長くなるため、ポットから土漏れが生じやすくなり、苗の品質が低下する。さらに、引き出した連続鉢苗の移動距離が長くなる分、連続鉢苗の連結片がねじれて育苗鉢が逆さまになる事態が増えることから、苗が損傷したり、育苗鉢が逆さまの状態で連続鉢苗が鉢苗案内部へ進入し、圃場に植付けられてしまうおそれがある。 In the continuous potted seedling transplanter described in Patent Document 1, when one volume of continuous potted seedlings is planted, it is necessary to pull out the next continuous potted seedlings to the guideway. In order to transplant the continuous potted seedlings on the upper stage without stopping the transplanter, the end of the continuous potted seedlings for the first seedling box and the tip of the continuous potted seedlings for the intermediate seedling box are separated. It is necessary to join with staples or the like. In this case, the tip of the continuous potted seedlings in the middle seedling box is pulled out to the end of the continuous potted seedlings for the first seedling box by traversing the seedling box, but the pulled out continuous potted seedlings are the seedlings in the seedling box There is a risk that the seedlings will be damaged by riding on the ground. In addition, since the moving distance of successive potted seedlings drawn out becomes long, soil leakage from the pots is likely to occur, resulting in deterioration of the quality of the seedlings. In addition, as the moving distance of the pulled-out continuous potted seedlings increases, the connecting pieces of the continuous potted seedlings are twisted and the situation where the seedling pot is turned upside down increases, so the seedlings may be damaged or the seedling pot may continue to be turned upside down. Potted seedlings may enter the potted seedling guide section and be planted in the field.

また、特許文献1に記載された連続鉢苗移植機では、育苗箱から引き出された連続鉢苗が上段又は下段案内部を移動して案内口まで導かれる際に、上段又は下段案内部の側枠に当接することによって直立姿勢に矯正された状態にて誘導路を通過させることができる。一方で、上段又は下段案内部の側枠は、3つの育苗箱を並列に載置した苗載置部の両側縁部から案内口へ向けて延びるものであり、当該側枠から距離のある中間の育苗箱の連続鉢苗が当該案内口まで導かれる際には、直立姿勢に矯正するための側板に当接する機会が極めて少なくなるため、連続鉢苗の姿勢が直立へ矯正されずに案内口に進入する事態が生じやすくなる。ましてやロングピッチの連続鉢苗では、通常の株間距離の連続鉢苗と比較して前後の個別鉢体の姿勢の影響を受け難いため、個々の個別鉢体を側枠に当接させることによって、それぞれの姿勢を直立に順次矯正する必要性がより大きい。 In addition, in the continuous potted seedling transplanter described in Patent Document 1, when the continuous potted seedlings pulled out from the seedling box move to the upper or lower guide part and are guided to the guide port, the side of the upper or lower guide part By contacting the frame, the guideway can be passed in a state corrected to an upright posture. On the other hand, the side frame of the upper or lower guide part extends from both side edges of the seedling placement part on which the three seedling boxes are placed in parallel toward the guide port, and is located in the middle at a distance from the side frame. When the continuous potted seedlings in the nursery box are guided to the guide port, the opportunity to contact the side plate for correcting the upright posture is extremely small, so the posture of the continuous potted seedlings is not corrected to the upright posture and the guide port It becomes easier for a situation to enter into Furthermore, continuous potted seedlings with a long pitch are less likely to be affected by the posture of the front and rear individual pots compared to continuous potted seedlings with a normal distance between plants. The need to sequentially correct each posture to upright is greater.

また、特許文献2に記載された連続鉢苗移植機では、標準的な移植機に対して移植機本体の全長が長くなるため、圃場の端位置での取回しが困難となるのに加え、圃場の終端部での移植不能距離が延びる。さらに、2冊分の連続鉢苗の移植が終了する度に、移植機を停止させて鉢苗載置部上の空の育苗箱を一冊分の連続鉢苗が収容された2冊の育苗箱と入れ替える必要があるため、作物の生産能率が低い。 In addition, in the continuous potted seedling transplanter described in Patent Document 2, the total length of the transplanter body is longer than that of a standard transplanter, so in addition to being difficult to handle at the edge position of the field. , increasing the non-transplantable distance at the end of the field. Furthermore, every time the transplantation of two consecutive potted seedlings is completed, the transplanter is stopped and the empty seedling-raising box on the potted-seedling-mounting part is replaced with two seedling-growing boxes containing one continuous potted seedling. The production efficiency of crops is low because it is necessary to replace them.

本発明は、作物生産の能率を向上させることが可能な連続鉢苗移植機を提供することを課題とする。 An object of the present invention is to provide a continuous pot seedling transplanter capable of improving the efficiency of crop production.

In addition to the driver of the tractor 11, a worker who handles the nursery box 15 rides on the tractor 11. - 特許庁An example of the work procedure performed by the worker will be described below. A ground working machine (“deep groove forming machine” in the first embodiment) of the tractor 11 is provided with a space (not shown) for a worker. For the sake of convenience, "the continuous potted seedlings 16 accommodated in the seedling box 15 set on the mounting part SOO" will be referred to as "the continuous potted seedlings 16 on the mounting part SOO".

まず、鉢苗載置部51Lの移植苗載置部S1Lと鉢苗載置部51Rの移植苗載置部S1Rとの間の待機苗載置部S3に育苗箱15をセットする。図3に示されるように、移植苗載置部S1Rにセットされた育苗箱15、及び待機苗載置部S3にセットされた育苗箱15には、一冊分の連続鉢苗16が収容されている。 First, the raising seedling box 15 is set in the standby seedling placement section S3 between the transplanted seedling placement section S1L of the potted seedling placement section 51L and the transplanted seedling placement section S1R of the potted seedling placement section 51R. As shown in FIG. 3, the seedling box 15 set in the transplanted seedling placement section S1R and the seedling box 15 set in the standby seedling placement section S3 accommodate one volume of continuous potted seedlings 16. ing.

一方、移植苗載置部S1Lにセットされた育苗箱15には、半冊分の連続鉢苗16が、育苗箱15の後部に詰めて収容されている。これにより、移植苗載置部S1L上の連続鉢苗16の前端のライン(辺)と、待機苗載置部S3上の連続鉢苗16の後端のライン(辺)とは、略同一直線上に位置する。なお、移植苗載置部S1L上の連続鉢苗16から引き出された一条の連続鉢苗16の先端部、及び移植苗載置部S1R上の連続鉢苗16から引き出された一条の連続鉢苗16の先端部は、圃場の植付け溝内に固定される。また、移植苗載置部S1L上の半冊分の連続鉢苗16の片割れは、補植用の苗等に使用する。 On the other hand, in the seedling box 15 set in the transplanted seedling placement section S1L, half a volume of continuous potted seedlings 16 are packed in the rear part of the seedling box 15 and accommodated. As a result, the front end line (side) of the continuous potted seedlings 16 on the transplanted seedling placement section S1L and the rear end line (side) of the continuous potted seedlings 16 on the standby seedling placement section S3 are substantially aligned. located on the line. Note that the tip portion of the row of continuous potted seedlings 16 pulled out from the continuous potted seedlings 16 on the transplanted seedling mounting portion S1L and the row of continuous potted seedlings pulled out from the continuous potted seedlings 16 on the transplanted seedling mounting portion S1R. The tip of 16 is fixed in the planting furrow of the field. In addition, the half of the continuous potted seedling 16 on the transplanted seedling placement section S1L is used for supplementary planting.

次に、トラクタ11を前進させて、移植苗載置部S1L上の半冊分の連続鉢苗16の移植、及び移植苗載置部S1R上の一冊分の連続鉢苗16の移植を開始する。移植が進行中、トラクタ11(対地作業機)上の作業者は、移植苗載置部S1L上の連続鉢苗16の末端と待機苗載置部S3上の連続鉢苗16の先端とをステープル等で接合する。なお、移植を開始する前の段階で、移植苗載置部S1L上の連続鉢苗16の末端と待機苗載置部S3上の連続鉢苗16の先端とを予め接合してもよい。 Next, the tractor 11 is advanced to start transplanting half a volume of continuous potted seedlings 16 on the transplanted seedling placement section S1L and one volume of continuous potted seedlings 16 on the transplanted seedling placement section S1R. do. While transplanting is in progress, a worker on the tractor 11 (ground work machine) staples the end of the continuous potted seedlings 16 on the transplanted seedling placement section S1L and the tip of the continuous potted seedlings 16 on the standby seedling placement section S3. etc. Before starting the transplanting, the ends of the continuous potted seedlings 16 on the transplanted seedling placement section S1L and the tips of the continuous potted seedlings 16 on the standby seedling placement section S3 may be joined in advance.

移植が進行して、移植苗載置部S1L上の半冊分(全て)の連続鉢苗16が育苗箱15から引き出されると、図4に示されるように、移植苗載置部S1L上の連続鉢苗16に連続して、待機苗載置部S3上の育苗箱15から一条の連続鉢苗16が引き出される。なお、待機苗載置部S3上の育苗箱15から引き出された一条の連続鉢苗16は、移植苗載置部S1L上の育苗箱15の右側端縁の側壁を乗り越えて、移植苗載置部S1L上の空の育苗箱15の後側端縁から鉢苗案内部21へ向かう経路で移動する。 When the transplanting progresses and the half volume (all) of the continuous potted seedlings 16 on the transplanted seedling placement section S1L are pulled out from the nursery box 15, as shown in FIG. Continuing to the continuous potted seedlings 16, a row of continuous potted seedlings 16 is pulled out from the nursery box 15 on the standby seedling placement part S3. The row of continuous potted seedlings 16 pulled out from the seedling box 15 on the waiting seedling placement section S3 climbs over the side wall at the right edge of the seedling box 15 on the transplanted seedling placement section S1L to place the transplanted seedlings. It moves along a route from the rear edge of the empty seedling box 15 on the part S1L toward the potted seedling guide part 21.例文帳に追加

次に、図5に示されるように、待機苗載置部S3上の育苗箱15を、平面視(上から見て)で時計回り方向へ回転させながらガイド板57Lに沿わせるようにして、移植苗載置部S1L側へ移動させる。これにより、移植苗載置部S1L上の空の育苗箱15は、待機苗載置部S3上の育苗箱15によって押されて隣の空箱収容部S2Lへ移動(スライド)する。なお、移植苗載置部S1L上の空の育苗箱15を隣の空箱収容部S2Lへ移動させた後、待機苗載置部S3上の育苗箱15を移植苗載置部S1Lにセットしてもよい。この場合、図6に示されるように、待機苗載置部S3上の育苗箱15から引き出された一条の連続鉢苗16は、鉢苗載置部51L上を滑動して鉢苗案内部21へ向かう経路で移動する。 Next, as shown in FIG. 5, the seedling box 15 on the standby seedling placement section S3 is rotated clockwise in plan view (viewed from above) so as to follow the guide plate 57L. It is moved to the transplanted seedling placement section S1L side. As a result, the empty seedling box 15 on the transplanted seedling placement section S1L is pushed by the seedling box 15 on the standby seedling placement section S3 and moved (slid) to the adjacent empty box storage section S2L. After moving the empty seedling box 15 on the transplanted seedling placement section S1L to the adjacent empty box storage section S2L, even if the seedling box 15 on the waiting seedling placement section S3 is set in the transplanted seedling placement section S1L. good. In this case, as shown in FIG. 6, the row of continuous potted seedlings 16 pulled out from the nursery box 15 on the standby seedling placement section S3 slides on the potted seedling placement section 51L and moves to the potted seedling guide section 21. move along the path to

次に、図7に示されるように、予備苗台13から育苗箱15を取り出して待機苗載置部S3にセットする。この時点で、移植苗載置部S1R上の育苗箱15から半冊分の連続鉢苗16が引き出されているので、移植苗載置部S1R上の育苗箱15内の連続鉢苗16を当該育苗箱15の後部へ移動させる(詰める)ことにより、移植苗載置部S1R上の連続鉢苗16の前端のライン(辺)と、待機苗載置部S3上の連続鉢苗16の後端のライン(辺)と、が略同一直線上に位置する。結果的に、図8に示されるように、移植苗載置部S1Rに、半冊分の連続鉢苗16が後部に詰めて収容された育苗箱15をセットした状態となる。 Next, as shown in FIG. 7, the raising seedling box 15 is taken out from the spare seedling stand 13 and set on the standby seedling placing section S3. At this point, half of the continuous potted seedlings 16 have been pulled out from the seedling box 15 on the transplanted seedling mount S1R, so the continuous potted seedlings 16 in the seedling box 15 on the transplanted seedling mount S1R are removed. By moving (packing) the seedling box 15 to the rear, the line (side) of the front end of the continuous potted seedlings 16 on the transplanted seedling placement section S1R and the rear end of the continuous potted seedlings 16 on the standby seedling placement section S3 are aligned. and are located on substantially the same straight line. As a result, as shown in FIG. 8, a seedling box 15 containing half a volume of continuous potted seedlings 16 is set in the transplanted seedling placement section S1R.

次に、移植苗載置部S1R上の連続鉢苗16の末端と待機苗載置部S3上の連続鉢苗16の先端とをステープル等で接合する。これにより、移植苗載置部S1R上の一冊分(全て)の連続鉢苗16が育苗箱15から引き出されると、移植苗載置部S1R上の連続鉢苗16に連続して、待機苗載置部S3上の育苗箱15から一条の連続鉢苗16が引き出される。このように、予備苗台13から取り出した育苗箱15を待機苗載置部S3に順次セットして、当該待機苗載置部S3上の連続鉢苗16の先端を、移植苗載置部S1L又は移植苗載置部S1R上の半冊分の連続鉢苗16の末端に接合する作業を繰り返すことにより、トラクタ11を停止させることなく、連続鉢苗移植機1L,1Rによる移植を連続して行うことができる。 Next, the ends of the continuous potted seedlings 16 on the transplanted seedling placement section S1R and the tips of the continuous potted seedlings 16 on the standby seedling placement section S3 are joined by staples or the like. As a result, when one volume (all) of the continuous potted seedlings 16 on the transplanted seedling placement unit S1R is pulled out from the seedling-raising box 15, the standby seedlings are continuously placed on the continuous potted seedlings 16 on the transplanted seedling placement unit S1R. A row of continuous potted seedlings 16 is pulled out from the nursery box 15 on the mounting portion S3. In this way, the raising seedling boxes 15 taken out from the preliminary seedling table 13 are sequentially set on the standby seedling mounting section S3, and the tips of the continuous potted seedlings 16 on the standby seedling mounting section S3 are placed on the transplanted seedling mounting section S1L. Alternatively, by repeating the operation of joining half a volume of the continuous potted seedlings 16 on the transplanted seedling placement section S1R to the ends, the transplanting by the continuous potted seedling transplanters 1L and 1R can be continuously performed without stopping the tractor 11. It can be carried out.

ここで、特許文献1に記載された連続鉢苗移植機では、一冊分の連続鉢苗の植付けが終わると、連続鉢苗移植機を停止させて、次の分の連続鉢苗を引き出して先端を圃場の植付け溝に固定する必要がある。また、特許文献2に記載された連続鉢苗移植機では、2冊分の連続鉢苗の植付けが終わる度に、連続鉢苗移植機を停止させて、鉢苗載置部上の空の育苗箱を、一冊分の連続鉢苗が収容された2冊の育苗箱と入れ替える必要がある。このように、従来の連続鉢苗移植機では、連続鉢苗移植機を停止させることなく、長距離を連続して移植することができなかったため、作物の生産能率を向上させるのが困難であった。 Here, in the continuous potted seedling transplanter described in Patent Document 1, when the planting of the continuous potted seedlings for one volume is completed, the continuous potted seedling transplanter is stopped and the next continuous potted seedlings are pulled out. The tip should be fixed in the planting furrow in the field. In addition, in the continuous pot seedling transplanter described in Patent Document 2, the continuous pot seedling transplanter is stopped every time the planting of two consecutive potted seedlings is completed, and the empty seedling box on the potted seedling mounting part is removed. , It is necessary to replace with two nursery boxes containing one continuous potted seedling. As described above, with the conventional continuous pot seedling transplanter, it was not possible to transplant continuously over a long distance without stopping the continuous pot seedling transplanter, so it was difficult to improve the production efficiency of crops. rice field.

これに対し、第1実施形態では、2台の連続鉢苗移植機1L,1Rをトラクタ11(レール12)に並列(横並び)に連結して、鉢苗載置部51Lと鉢苗載置部51Rとの間に、連続鉢苗移植機1L又は1Rで次に移植される連続鉢苗16を収容した育苗箱15を載置する待機苗載置部S3を設けた。そして、鉢苗載置部51L,51Rの移植苗載置部S1L,S1R上の育苗箱15,15の後端が、待機苗載置部S3上の育苗箱15の後端よりも後方に位置するように、移植苗載置部S1L、移植苗載置部S1R、待機苗載置部S3を配置した。 On the other hand, in the first embodiment, two continuous potted seedling transplanters 1L and 1R are connected in parallel (horizontal) to the tractor 11 (rail 12), and the potted seedling placing section 51L and the potted seedling placing section 51L are connected to each other. 51R, a standby seedling placement section S3 for placing a nursery box 15 containing successive potted seedlings 16 to be next transplanted by the continuous potted seedling transplanter 1L or 1R is provided. The rear ends of the seedling boxes 15, 15 on the transplanted seedling mounts S1L, S1R of the potted seedling mounts 51L, 51R are located behind the rear ends of the seedling boxes 15 on the standby seedling mount S3. Transplanted seedling mounting part S1L, transplanted seedling mounting part S1R, and standby seedling mounting part S3 are arranged so as to do.

さらに、第1実施形態では、移植の開始時に、鉢苗載置部51Lの移植苗載置部S1Lに半冊分の連続鉢苗16が収容された育苗箱15をセットするとともに、鉢苗載置部51Rの移植苗載置部S1Rに一冊分の連続鉢苗16が収容された育苗箱15をセットして、待機苗載置部S3上の連続鉢苗16の先端を、移植苗載置部S1L上の半冊分の連続鉢苗16の末端に接合した。即ち、鉢苗載置部51L,51R間で、連続鉢苗16に半冊分の差を設けている。 Furthermore, in the first embodiment, at the start of transplanting, the nursery box 15 containing half a volume of continuous potted seedlings 16 is set in the transplanted seedling mounting portion S1L of the potted seedling mounting portion 51L, and The seedling box 15 containing one continuous potted seedling 16 is set on the transplanted seedling mounting portion S1R of the placing portion 51R, and the tip of the continuous potted seedling 16 on the standby seedling mounting portion S3 is placed on the transplanted seedling mounting portion. It was joined to the end of the continuous potted seedling 16 for half volume on the placing part S1L. That is, between the potted seedling mounting portions 51L and 51R, the continuous potted seedlings 16 are separated by half a volume.

第1実施形態によれば、予備苗台13から取り出した育苗箱15を待機苗載置部S3に順次セットして、待機苗載置部S3上の連続鉢苗16の先端を、移植苗載置部S1L又は移植苗載置部S1R上の半冊分の連続鉢苗16の末端に接合する作業を繰り返すことにより、トラクタ11を停止させることなく、連続鉢苗移植機1L,1Rによる移植を連続して行うことが可能であり、作物の生産能率を向上させることができる。 According to the first embodiment, the raising seedling boxes 15 taken out from the preliminary seedling table 13 are sequentially set on the standby seedling mounting section S3, and the tips of the continuous potted seedlings 16 on the standby seedling mounting section S3 are placed on the transplanted seedling mounting section. By repeating the operation of joining half of the continuous potted seedlings 16 on the seedling placing portion S1L or the transplanted seedling placing portion S1R at the ends thereof, transplantation by the continuous potted seedling transplanters 1L and 1R can be performed without stopping the tractor 11. It can be performed continuously, and the production efficiency of crops can be improved.

また、特許文献1に記載された連続鉢苗移植機では、隣接する育苗箱間の連続鉢苗の先端と末端とをステープル等で接合した場合、一方の育苗箱から引き出された連続鉢苗を、育苗箱を縦断させてその先端を他方の育苗箱の末端に接合させるので、引き出された連続鉢苗が育苗箱内の苗に乗り上げて、苗が損傷するおそれがあった。さらに、引き出した連続鉢苗の移動距離が長くなると、ポットから土漏れが生じやすくなり、苗の品質を低下させる原因になっていた。また、引き出した連続鉢苗の移動距離が長くなる分、連続鉢苗の連結片がねじれて育苗鉢が逆さまになる事態が増えることから、苗が損傷したり、育苗鉢が逆さまの状態で連続鉢苗が鉢苗案内部へ進入し、圃場に植付けられてしまうおそれがある。 In addition, in the continuous potted seedling transplanter described in Patent Document 1, when the tip and end of the continuous potted seedlings between adjacent seedling boxes are joined with staples or the like, the continuous potted seedlings pulled out from one seedling box are transferred. Since the seedling box is traversed longitudinally and the tip is joined to the end of the other seedling box, there is a risk that the consecutive potted seedlings pulled out will ride on the seedlings in the seedling box and damage the seedlings. Furthermore, when the moving distance of successively drawn seedlings in pots is long, soil leakage from the pots is likely to occur, causing deterioration in the quality of the seedlings. In addition, as the moving distance of the consecutive potted seedlings that are pulled out increases, the connecting pieces of the consecutive potted seedlings are twisted and the situation where the seedling pots are turned upside down increases, so the seedlings are damaged and the seedling pots are continuously turned upside down. Potted seedlings may enter the potted seedling guide section and be planted in the field.

これに対し、第1実施形態では、移植苗載置部S1L又はS1R上の半冊分の連続鉢苗16の前端(辺)の位置と待機苗載置部S3上の一冊分の連続鉢苗16の後端(辺)の位置とが略一致するので、連続鉢苗1の、待機苗載置部S3から移植苗載置部S1L又はS1Rまでの移動距離を短くすることができ、苗の品質が確保される。 On the other hand, in the first embodiment, the positions of the front ends (sides) of half the continuous potted seedlings 16 on the transplanted seedling placement section S1L or S1R and the one continuous pot on the standby seedling placement section S3. Since the positions of the rear ends (sides) of the seedlings 16 substantially coincide with each other, the moving distance of the continuous potted seedlings 1 from the waiting seedling placement section S3 to the transplanted seedling placement section S1L or S1R can be shortened. quality is ensured.

さらに、特許文献2に記載された連続鉢苗移植機では、標準的な移植機に対して移植機本体の全長が長くなるため、圃場の端位置での取回しが困難であるのに加え、圃場の終端部での移植不能距離が延びることが問題であったが、第1実施形態では、標準的な連続鉢苗移植機と比較して連続鉢苗移植機1L,1Rの全長が延びることがないので、このような問題を回避することができる。 Furthermore, in the continuous potted seedling transplanter described in Patent Document 2, since the total length of the transplanter body is longer than that of a standard transplanter, it is difficult to handle at the edge of the field. However, in the first embodiment, the total length of the continuous pot seedling transplanters 1L and 1R is longer than that of the standard continuous pot seedling transplanter. Since there is no such problem, such problems can be avoided.

また、第1実施形態では、待機苗載置部S3上の育苗箱15をガイド板57L,57Rに沿わせるように移植苗載置部S1L,S1R側へ移動させるのに並行して、移植苗載置部S1L,S1R上の空の育苗箱15が待機苗載置部S3上の育苗箱15によって押し出されて隣の空箱収容部S2L,S2Rへ移動させることができるので、移植苗載置部S1L,S1R上の空の育苗箱15を空箱収容部S2L,S2Rへ移動させてから、待機苗載置部S3上の育苗箱15を移植苗載置部S1L,S1Rへセットする場合と比較して、作業の能率を向上させることが可能である。 In addition, in the first embodiment, in parallel with moving the seedling box 15 on the standby seedling placement section S3 toward the transplanted seedling placement sections S1L and S1R along the guide plates 57L and 57R, the transplanted seedlings Since the empty seedling boxes 15 on the placement sections S1L and S1R can be pushed out by the seedling boxes 15 on the standby seedling placement section S3 and moved to the adjacent empty box storage sections S2L and S2R, the transplanted seedling placement section S1L. , S1R to the empty box storage units S2L and S2R, and then set the seedling boxes 15 on the standby seedling placement unit S3 to the transplanted seedling placement units S1L and S1R. It is possible to improve work efficiency.
