（作用）
次に、本実施形態の作用を説明する。ここでは、前述した連結機構３１により、６台の苗移植機１が、並列に、すなわち、横並びの状態で、トラクタ５１（農業機械）のロータリ装置５２の後部に設けられたロータリアタッチ５３に連結される。なお、移植対象は、育苗箱８に収容された連続鉢苗７の各個別鉢体にて育苗されたラッキョウの苗である。 (Action)
Next, the operation of this embodiment will be described. Here, the six seedling transplanters 1 are connected in parallel, that is, in a side-by-side manner to the rotary rear touch 53 provided at the rear part of the rotary device 52 of the tractor 51 (agricultural machine) by the connecting mechanism 31 described above. To be done. It should be noted that the transplant target is a Rakkyo seedling grown in each individual pot of the continuous pot seedlings 7 housed in the seedling raising box 8.

まず、各苗移植機１の苗台４（鉢苗載置部）に、連続鉢苗７を収容した育苗箱８をセットする。なお、育苗箱８の底部と連続鉢苗７との間（連続鉢苗７の下に下敷き紙が敷いてある場合、下敷き紙と育苗箱８の底部との間）には、スロープ（図示省略）が差し込まれることにより、育苗箱８と鉢苗案内部５の底板９との段差が解消される。また、連続鉢苗７は、接着に使用された水溶性の糊が溶ける程度に湿らされている。   First, the seedling raising box 8 containing the continuous potted seedlings 7 is set on the seedling stand 4 (potted seedling placing portion) of each seedling transplanting machine 1. A slope (not shown) is provided between the bottom of the seedling raising box 8 and the continuous potted seedling 7 (when the seedling paper is laid under the continuous potted seedling 7, between the seedling paper and the bottom of the seedling raising box 8). ) Is inserted, the step between the seedling raising box 8 and the bottom plate 9 of the potted seedling guide portion 5 is eliminated. In addition, the continuous potted seedling 7 is moistened to such an extent that the water-soluble glue used for adhesion is melted.

次に、トラクタ５１を圃場の移植開始位置に停止させ、さらにロータリアタッチ５３を下降させた後、トラクタ５１を一定距離だけ前進させる。これにより、ロータリ装置５２（耕耘装置）により圃場が耕され、当該圃場の耕された部分には、各苗移植機１の作溝部２１により植付溝２０が成形され、併せて、当該植付溝２０の底部には、溝切部２５により底溝（定植溝）が形成される。   Next, the tractor 51 is stopped at the transplantation start position in the field, the rotary touch 53 is further lowered, and then the tractor 51 is advanced by a certain distance. Thereby, the field is cultivated by the rotary device 52 (cultivating device), and the planting groove 20 is formed in the cultivated portion of the field by the grooving portion 21 of each seedling transplanter 1, and the planting is also performed. A bottom groove (fixed plant groove) is formed at the bottom of the groove 20 by the groove cut portion 25.

次に、各苗移植機１の苗台４上に載置された育苗箱８から１条の連続鉢苗７を引き出し、引き出された連続鉢苗７を、鉢苗案内部５の一対の案内板１０Ｌ、１０Ｒ間、及び鉢苗繰出部６の誘導板１３に通して、各苗移植機１の連続鉢苗７の先端部を、圃場に成形された対応する各植付溝２０の底溝に定植、換言すると、各植付溝２０の底部に固定する。この状態で、ロータリ装置５２を作動させながらトラクタ５１を前進させると、トラクタ５１の前進に伴い、圃場には、各苗移植機１の作溝部２１により６条の植付溝２０が引き続き成形され、同時に、各植付溝２０の底部には、各本体２の溝切部２５により底溝（定植溝）が形成される。   Next, one row of continuous potted seedlings 7 is pulled out from the seedling raising box 8 placed on the seedling stand 4 of each seedling transplanter 1, and the pulled out continuous potted seedlings 7 are guided by a pair of potted seedling guide portions 5. The tip of the continuous potted seedling 7 of each seedling transplanter 1 is passed through the guide plates 13 of the pots 10L and 10R and the potted seedling feeding section 6, and the bottom groove of each corresponding planting groove 20 formed in the field. The planting, that is, fixed to the bottom of each planting groove 20. In this state, when the tractor 51 is moved forward while operating the rotary device 52, the six grooving grooves 20 are continuously formed in the field by the grooving portion 21 of each seedling transplanter 1 as the tractor 51 moves forward. At the same time, a bottom groove (fixed plant groove) is formed at the bottom of each planting groove 20 by the groove cut portion 25 of each main body 2.

そして、各苗移植機１の作溝部２１による植付溝２０の成形、及び溝切部２５による底溝の形成に併せて、鉢苗案内部５により整列された１条の連続鉢苗７が、各苗移植機の鉢苗繰出部６から繰り出される、換言すると、各苗移植機１の切欠部２４から繰り出される。当該各苗移植機１の鉢苗繰出部６から繰り出された１条の連続鉢苗７は、圃場に成形された対応する各植付溝２０の底溝に順次定植される。   Then, along with the molding of the planting groove 20 by the groove 21 of each seedling transplanter 1 and the formation of the bottom groove by the groove 25, one continuous potted seedling 7 aligned by the potted seedling guide 5 is obtained. , Is fed from the potted seedling feeding section 6 of each seedling transplanting machine, in other words, it is fed from the notch section 24 of each seedling transplanting machine 1. One row of continuous potted seedlings 7 fed from the potted seedling feeding section 6 of each seedling transplanting machine 1 is sequentially planted in the bottom groove of each corresponding planting groove 20 formed in the field.

（効果）
本実施形態によれば、圃場に植付溝２０を成形する作溝部２１と、当該作溝部２１により成形された植付溝２０の底部に底溝（定植溝）を形成する溝切部２５と、を本体２（移植機本体）に設けて苗移植機１を構成したので、当該苗移植機１により作溝と定植とを同時に行うことができる。
これにより、従来の管理機等による作溝作業を省くことが可能であり、連続鉢苗７の移植に係る一連の作業を能率化することができる。また、当該苗移植機１をトラクタ５１（農業機械）のロータリ装置５２（耕耘装置）のロータリアタッチ５３（後部）に連結させる連結機構３１を備えているので、移植の前に管理機等にて作溝する場合と比較して、連続鉢苗７の移植作業を大幅に能率化することができると共に作業者の負担を軽減することができる。
また、従来、別途形成された植付溝２０に連続鉢苗７が移植されるため、当該植付溝２０の側壁が自然崩落したり、苗移植機の移動に伴い崩落することで、連続鉢苗を移植することができなくなったり、移植後の連続鉢苗に土が被さって苗の生育に支障を来す不具合を生じていたが、本実施形態では、植付溝２０の成形と連続鉢苗７の移植とを同時に行うことが可能であるため、このような事態を解消することができる。
加えて、従来、管理機等による作溝から苗移植機による定植が完了するまでの間、移植作業、準備作業、強風等により植付溝２０の側壁が崩落した場合、連続鉢苗７を適正深さで定植することができなくなり、土寄せ、除草、培土等の定植後の管理作業が困難になることがあったが、本実施形態では、植付溝２０の成形と連続鉢苗７の移植とを同時に行うことが可能であるため、このような事態をも解消することができる。
また、作溝部２１は、圃場に植付溝２０を成形する、すなわち、圃場に植付溝２０を形成しながら当該植付溝２０の側壁をＶ形状に整形するので、例えば、砂丘地等の軟弱な圃場における植付溝２０の側壁の崩落を防ぐことができる。
さらに、作溝部２１により成形された植付溝２０（深溝）に連続鉢苗７が定植されるので、当該植付溝２０の幅方向両側に盛られた土による培土により、日光や空気に晒されることによる連続鉢苗７（例えば「ラッキョウ」）の品質の低下を防ぐことができる。 (effect)
According to the present embodiment, the work groove portion 21 that forms the planting groove 20 in the field, and the groove cutting portion 25 that forms the bottom groove (set plant groove) at the bottom of the planting groove 20 formed by the work groove portion 21. Since the seedling transplanter 1 is configured by providing the main body 2 (transplanter main body) with, the seedling transplanter 1 can simultaneously perform cropping and planting.
As a result, it is possible to omit the conventional grooving work using a management machine or the like, and it is possible to streamline a series of work related to transplanting the continuous potted seedling 7. Further, since the seedling transplanting machine 1 is provided with the connecting mechanism 31 for connecting the rotary device 52 (cultivating device) of the tractor 51 (agricultural machine) to the rotary rear touch 53 (rear part) thereof, a management machine or the like is used before the transplanting. Compared with the case of making a groove, the work of transplanting the continuous potted seedlings 7 can be significantly streamlined and the burden on the operator can be reduced.
Further, since the continuous pot seedling 7 is conventionally transplanted to the separately formed planting groove 20, the side wall of the planting groove 20 naturally collapses or collapses as the seedling transplanter moves, so that the continuous potted plant Although the seedlings cannot be transplanted or the seedlings are continuously covered with soil after the transplantation, there is a problem that the growth of the seedlings is hindered. However, in the present embodiment, molding of the planting groove 20 and continuous potting are performed. Since the seedling 7 can be transplanted at the same time, such a situation can be eliminated.
In addition, conventionally, when the side wall of the planting groove 20 collapses due to transplanting work, preparatory work, strong wind, etc., from the time when the planting groove by the management machine is completed until the planting by the seedling transplanting machine is completed, the continuous potted seedling 7 is appropriate. Although it became impossible to plant at a depth, management work such as soil gathering, weeding, cultivating soil, etc. after planting became difficult in some cases, but in the present embodiment, molding of the planting groove 20 and transplant of the continuous potted seedlings 7 are performed. Since it is possible to perform and at the same time, it is possible to eliminate such a situation.
In addition, since the working groove portion 21 forms the planting groove 20 in the field, that is, because the side wall of the planting groove 20 is shaped into a V shape while forming the planting groove 20 in the field, for example, in a dune or the like. It is possible to prevent the side wall of the planting groove 20 from collapsing in a weak field.
Further, since the continuous potted seedlings 7 are planted in the planting groove 20 (deep groove) formed by the grooving portion 21, the soil is piled up on both sides in the width direction of the planting groove 20 so that the soil is exposed to sunlight or air. It is possible to prevent the quality of the continuous potted seedlings 7 (for example, "Rakkyo") from being deteriorated due to this.

It can be applied to transplantation.
Further, in the present embodiment, since the seedling table 4 (potted seedling placing portion) is inclined in the left-right direction with respect to the horizontal plane, the seedling table 4 is installed horizontally, and by extension, the seedling raising box 8 is provided by the seedling table 4. It is possible to reduce the horizontal interval occupied by the seedling raising box 8 in comparison with the case where the seedling raising box 8 is supported horizontally, and, by extension, the horizontal interval is the minimum mounting pitch P between the adjacent main bodies 2. It can be suppressed to the following. As a result, multiple-row simultaneous transplantation is possible in rows that are narrower than the width of the nursery box 8 (for example, 30 cm). For example, seedlings such as lacquer, onions, etc. can be transferred at regular intervals (for example, 24 cm) in multiple rows. Can be transplanted.

また、本実施形態では、連結機構３１により、複数台の苗移植機１をトラクタ５１のロータリ装置５２のロータリアタッチ５３（後部）に連結したので、作業者は、トラクタ５１の運転席から複数条の連続鉢苗７の移植状態を目視することができる。
