【産業上の利用分野】
本発明は、育苗容器用土供給装置に係るものである。
【０００２】
【従来技術】
従来、育苗容器を移送する移送台の上方位置に、上部のホッパーと下部の供給ベルト等からなる土繰出装置と、前記ホッパーに土を補給するバケットを有する補給コンベアとからなるものは、公知である。
【０００３】
【発明が解決しようとする課題】
前記公知例は、ホッパーに一旦土を貯留し、ベルトにより設定した供給量を繰り出す構成であるから、必ず、ホッパーとベルトとこれらを取付けるフレームと、その他付属品を有する土繰出装置が必要であり、かつ、これに土を補給する補給コンベアを組合せていた。
したがって、部品点数が多いという課題がある。
しかし、余分に土を供給してから取り除いて設定量にするように、発想を変えると、前記土繰出装置を不要にした土供給装置を構成できる。
【０００４】
【発明の目的】
構成の簡素化、部品点数の削減、コストダウン。
【０００５】
【課題を解決するための手段】
本発明は、左右一対の移送台フレーム１９に移送手段３０を設けて上面を開放した引き出し形状または上部を開口したポットを縦横に並べた育苗容器２を移送し得る移送台４に、前記育苗容器２の上面より高い縦板により形成され前記育苗容器２を案内するガイド兼起立部材３６と、前記育苗容器２の上面側を摺接するスクレーパ３１とを設け、前記移送台４の一側には移送中の前記育苗容器２の上方に土を上昇させるバケット６を有するバケットコンベア５を設け、該バケットコンベア５により直接前記育苗容器２の上方に土を供給するようにした育苗容器用土供給装置としたものである。
本発明は、前記ガイド兼起立部材３６の終端と前記スクレーパ３１との間には土が落下する隙間を形成した育苗容器用土供給装置としたものである。
本発明は、前記スクレーパ３１の移送方向前側には前記育苗容器２に供給した土の上面を掃く回転ブラシ３３を設けた育苗容器用土供給装置としたものである。
本発明は、前記バケットコンベア５は前記移送台４の搬送方向に対して交差方向にバケット６を上昇するように配置し、バケットコンベア５の上部には移送台４の移送方向に対する交差方向に放擲した土３を、移送台４の移送方向と並行方向であって移送台４の始端部側に誘導する誘導樋２５を設けた育苗容器用土供給装置としたものである。
本発明は、前記バケットコンベア５には上部のホッパー１７と下部の搬送ベルト１８により土を供給する供給兼回収戻し装置１６を接続した育苗容器用土供給装置としたものである。
本発明は、前記前記ホッパー１７は前記移送台４の下方に位置して落下する土を受け入れる回収部２０と、移送台４とは重合せず土を張り込む張込部２１とにより構成した育苗容器用土供給装置としたものである。
本発明は、前記移送台４は前記ホッパー１７に取付けた育苗容器用土供給装置としたものである。
【０００６】
【実施例】
図により本発明の一実施例を説明すると、１は育苗容器２に土３を供給する土供給装置であり、育苗容器２を移送する移送台４の左右何れか一側にバケットコンベア５を設ける。バケットコンベア５は、前記移送台４による育苗容器２の移送方向と交差方向に上下移動するバケット６により構成し、バケット６は無端チエン７の外周に所定間隔を置いて複数個取付け、無端チエン７は上部回転軸８と該上部回転軸８と対となる下部回転軸９の夫々に固定のスプロケット１０と下部回転軸９に固定のスプロケット１１との間に掛け回す。前記上部回転軸８にはコンベア用モーター１２を直接または間接的に連結する。
【０００７】
しかして、バケットコンベア５の下部の、前記バケット６の回転下降側には供給兼回収戻し装置１６を設ける。供給兼回収戻し装置１６は上方にホッパー１７を設け、下方に搬送ベルト１８を設けて構成する。前記ホッパー１７は前記移送台４を支持するフレームを兼用し、ホッパー１７のバケットコンベア５側の上方位置に移送台４の左右の移送台フレーム１９を固定し、該移送台４の下方のホッパー１７部分が供給兼回収戻し装置１６の回収部２０となる。
また、前記ホッパー１７は、前記移送台４の反バケットコンベア５側より側方に長く所定長さ突出させて上面を移送台４と重合しない開放した張込部２１に形成する。張込部２１はフォークリフト２２等によって土を張り込める大きさの開口部を設けると、作業が容易になって好適である。
【０００８】
そして、前記ホッパー１７の終端（バケットコンベア５）側は前記バケットコンベア５の下部に接続してバケット６が土を掬えるように構成する。
２３は搬送ベルト１８の駆動ローラー、２４は搬送ベルト１８の受動ローラーである。
しかして、前記バケットコンベア５の上部には誘導樋２５を設ける。誘導樋２５は前記バケットコンベア５の排出口２６に接続して前記移送台４側に低く傾斜する接続部２７と、移送台４の移送方向に対する交差方向に放擲した土３を、移送台４の移送方向と並行方向であって移送台４の始端部側に誘導する誘導部２８により形成する。誘導部２８は移送台４の左右の略中央上方に位置させる。
前記移送台４は、前記育苗容器２を移送する移送手段３０を前記移送台フレーム１９に設け、前記移送手段３０の上方で前記誘導樋２５の移送方向前側にはスクレーパ３１を設ける。スクレーパ３１は平面視中央が後側で左右側が前側となるＶ形状のゴム等の弾性部材により形成し、スクレーパ３１は前記移送台４に設けた左右一対の支柱３２に高さ調節自在に取付ける。また、バケットコンベア５による土の供給量が特に多いときにはスクレーパ３１を前後に並設することもある。
【０００９】
前記スクレーパ３１の前側には、育苗容器２に供給した土の上面を掃く回転ブラシ３３を設ける。回転ブラシ３３は、公知構成であり、図示は省略するが左右一対のアームの先端に軸装して、駆動回転させ、前記アームに設けた高さ調節装置により高さ調節自在に取付ける。
しかして、前記移送台４には前記育苗容器２を案内するガイド兼起立部材３６を左右一対設ける。即ち、前記育苗容器２は、図示は省略するが上面を開放した引き出し形状の苗箱と呼ばれるものや、枠体３７にポット３８を嵌合させたものにより構成し、該育苗容器２を移送台４により移送するため、前記苗箱や枠体３７の側部を前記ガイド兼起立部材３６に摺接させて、育苗容器２の移送を案内させると共に、前記ガイド兼起立部材３６の上端は苗箱やポット３８の上縁より遥かに高く形成し、左右のガイド兼起立部材３６と育苗容器２の上面により貯留空間４０を形成し、該貯留空間４０にバケットコンベア５により間欠供給される土を貯留させることでホッパーの作用を期待し、必要充分量より多い土を最初に供給し、次ぎに、前記スクレーパ３１により余分な土を除去することにより供給量を設定量にする。
【００１０】
したがって、ガイド兼起立部材３６は縦板により形成し、始端部は前記バケットコンベア５の誘導樋２５より所定間隔を置いて後側に位置させ、ガイド兼起立部材３６の終端部（前端部）と前記スクレーパ３１（スクレーパ３１を複数並設したときは手前のスクレーパ３１）との間には土が落下する隙間４１を形成するように配置する。また、ガイド兼起立部材３６は左右幅およびに高さ調節自在にフレーム１９に取付けると、大きさの相違する育苗容器２に対応させることができ、好適である（図４）。
しかして、前記供給兼回収戻し装置１６のホッパー１７は、側面視Ｖ形状に形成し、移送台４より落下する土を回収し得るようにし、例えば、その前板４２の上端を前記ガイド兼起立部材３６の始端部より移送台４の始端部側とし、その後板４３後板４３は前記回転ブラシ３３より前側に位置させると、確実に土を回収でき、好適である。
また、ホッパー１７には走行車輪４４を設け、移送台４とバケットコンベア５と供給兼回収戻し装置１６を一体的に移動し得るようにしている。走行車輪４４は自在輪（キャスター輪）であって、ストッパ機構付きにすると、操作性・作業性を向上させる。
【００１１】
【作用】
次に作用を述べる。
供給兼回収戻し装置１６のホッパー１７の張込部２１に篩土を投入し、全体のスイッチをオンにすると、供給兼回収戻し装置１６およびバケットコンベア５および移送台４に通電される。
ホッパー１７の張込部２１に投入された篩土は、搬送ベルト１８によりバケットコンベア５の下部に搬送され、ホッパー１７の終端で反転して上昇するバケット６が土を上昇させて上方位置にて放擲し、放擲された土はバケットコンベア５の誘導樋２５により移送台４の移送方向と並行方向に流下方向が変換されて、移送台４の上方に落下する。
【００１２】
このとき、移送台４には育苗容器２が移送されているから、誘導樋２５より落下した土は育苗容器２に供給される。
この場合、バケットコンベア５は移送中の育苗容器２の上方に土を落下させるだけであるが、移送台４には移送中の育苗容器２を案内するガイド兼起立部材３６を左右一対設け、ガイド兼起立部材３６は育苗容器２のポット３８または苗箱の上縁より遥かに高く形成しているから、バケットコンベア５より供給された多量の土は育苗容器２上面と左右のガイド兼起立部材３６とスクレーパ３１に囲まれた貯留空間４０内に貯留され、スクレーパ３１の下方を通過するときに、供給設定量にされる。
【００１３】
即ち、従来のように繰出口を調節して育苗容器２に所定量の土を落下させるのではなく、育苗容器２上に多量に供給し、その後スクレーパ３１により供給設定量にするという構成により、特に、移送台４の上方にホッパーおよび繰出ベルトからなる土繰出装置は設けず、また、バケットコンベア５はバケット６による間欠供給であるが、移送台４に左右一対のガイド兼起立部材３６とスクレーパ３１を設けるだけですみ、構成を頗る簡素にできる。この場合、従来も、スクレーパ３１や回転ブラシ３３を設けているが、これは、土上面を均平にできるだけの数mmあるいは１cm程度余分に供給して除去する方法であって、育苗容器２全体にくまなく供給するための数cm以上の多量供給と相違し、ホッパと供給ベルト等を必要とする土繰出装置を省略できるものではない。したがって、多量供給とスクレーパ３１による除去の構成にすることにより、ホッパーおよび繰出ベルトからなる土繰出装置の省略を実現できる。
多量供給を前提とするから、精密な供給量の設定が不要となって、バケットコンベア５による直接供給が可能になって、この点でもコストを低くできる。即ち、従来の土繰出装置では、繰出口に少し大きい土塊が詰まっただけで、この部分から土は供給されず、供給量に斑が発生し、そのため、土の種類や繰出口の開口面積の精密な調節を必要とするが、本願の場合は、多量供給後に除去するのでバケットコンベア５による直接供給が可能になって、操作性・作業性を向上させる。
【００１４】
また、バケットコンベア５は移送台４の移送方向に対して交差方向に土を放擲しているが、バケットコンベア５の上部に設けた誘導樋２５が移送方向と並行に流下方向を変換させているので、土は育苗容器２の上方の左右両側に流下させることができ、誘導樋２５との相乗作用によって、ポット３式の育苗容器２でも各ポット３８に土を確実に供給できる。
しかして、前記移送台４は、その移送台フレーム１９の前後略中央部を供給兼回収戻し装置１６のホッパー１７上に載置固定し、ホッパー１７の前板４２および後板４３は移送台４より土が落下する範囲に設けているから、移送台４にて育苗容器２に供給した土のうち余った土は供給兼回収戻し装置１６のホッパー１７の回収部２０に落下して、張り込んだ土と合流してバケットコンベア５により、育苗容器２に供給する。
【００１５】
したがって、育苗容器２に多量の土を供給し、多量の土を落下させるが、バケットコンベア５に供給兼回収戻し装置１６を組合せることにより、作業を連続させることができ、作業を簡単にでき、また、移送台４は支脚を特別に設けることなく構成でき、部品点数も減少させる。
しかして、バケットコンベア５が上昇させる土の量と、育苗容器２に供給する土の量を完全に一致させることはできないので、従来では、複雑な制御を行っており、そのため、構造も複雑になっていたが、バケットコンベア５は育苗容器２に対する供給量よりやや多く設定するだけで、余分な土は供給兼回収戻し装置１６のホッパー１７に落下させて循環させるので、この点でも、構成が簡単であり、部品点数を減少させることができる。
【００１６】
しかして、ホッパー１７は、移送台４の反バケットコンベア５側より側方に所定長さ突出させて上面を移送台４と重合しない開放した張込部２１に形成しているから、張込部２１にフォークリフト２２等によって土を張り込めるので、作業が容易にでき、また、バケットコンベア５の下部に供給ホッパーを設けなく済み、部品点数を減少させて、コストダウンでき、また、メンテナンス部分を少なくできて、好適である。
【００１７】
【効果】
本発明は、左右一対の移送台フレーム１９に移送手段３０を設けて上面を開放した引き出し形状または上部を開口したポットを縦横に並べた育苗容器２を移送し得る移送台４に、前記育苗容器２の上面より高い縦板により形成され前記育苗容器２を案内するガイド兼起立部材３６と、前記育苗容器２の上面側を摺接するスクレーパ３１とを設け、前記移送台４の一側には移送中の前記育苗容器２の上方に土を上昇させるバケット６を有するバケットコンベア５を設け、該バケットコンベア５により直接前記育苗容器２の上方に土を供給するようにした育苗容器用土供給装置としたものであるから、従来のような土繰出装置を省略して、構成を簡素にでき、部品点数を削減してコストダウンできる。
本発明は、前記ガイド兼起立部材３６の終端と前記スクレーパ３１との間には土が落下する隙間を形成した育苗容器用土供給装置としたものであるから、余分な土は落下させて、育苗容器２の上方に必要以上に土を貯留させないので、設定した供給量に確実にできる。
本発明は、前記スクレーパ３１の移送方向前側には前記育苗容器２に供給した土の上面を掃く回転ブラシ３３を設けた育苗容器用土供給装置としたものであるから、余分な土を除去すると共に、土上面を均平できる。
本発明は、前記バケットコンベア５は前記移送台４の搬送方向に対して交差方向にバケット６を上昇するように配置し、バケットコンベア５の上部には移送台４の移送方向に対する交差方向に放擲した土３を、移送台４の移送方向と並行方向であって移送台４の始端部側に誘導する誘導樋２５を設けた育苗容器用土供給装置としたものであるから、合理的な配置にできると共に、確実に左右均等に土を供給できる。
本発明は、前記バケットコンベア５には上部のホッパー１７と下部の搬送ベルト１８により土を供給する供給兼回収戻し装置１６を接続した育苗容器用土供給装置としたものであるから、供給作業を容易にできる。
本発明は、前記前記ホッパー１７は前記移送台４の下方に位置して落下する土を受け入れる回収部２０と、移送台４とは重合せず土を張り込む張込部２１とにより構成した育苗容器用土供給装置としたものであるから、多量に供給することでバケットコンベア５による間欠供給の欠点を解消し、この多量供給の問題を供給兼回収戻し装置１６により回収してバケットコンベア５に循環させることで解消できる。
本発明は、前記移送台４は前記ホッパー１７に取付けた育苗容器用土供給装置としたものであるから、移送台４の支持構造を省略でき、部品点数も減少させる。

The present invention is a seedling container soil supply device in which the bucket conveyor 5 is connected to a supply and recovery device 16 for supplying soil by an upper hopper 17 and a lower conveyor belt 18.
In the present invention, the hopper 17 is located below the transfer table 4 and receives a falling soil, and a seedling that is composed of a tensioning unit 21 that does not overlap with the transfer table 4 and pastes the soil. This is a container soil supply device.
In the present invention, the transfer table 4 is a seedling container soil supply device attached to the hopper 17.
[0006]
【Example】
An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a soil supply device for supplying soil 3 to a seedling container 2, and a bucket conveyor 5 is provided on one of the left and right sides of a transfer table 4 for transferring the seedling container 2. . The bucket conveyor 5 includes a bucket 6 that moves up and down in a direction intersecting with the transfer direction of the seedling container 2 by the transfer table 4. A plurality of buckets 6 are attached to the outer periphery of the endless chain 7 at a predetermined interval. The upper rotary shaft 8 and the lower rotary shaft 9 paired with the upper rotary shaft 8 are respectively wound around a sprocket 10 fixed to the lower rotary shaft 9 and a sprocket 11 fixed to the lower rotary shaft 9. A conveyor motor 12 is directly or indirectly connected to the upper rotating shaft 8.
[0007]
Thus, a supply and recovery device 16 is provided on the lower side of the bucket 6 at the lower side of the rotation of the bucket 6. The supply / collection return device 16 is configured by providing a hopper 17 on the upper side and a conveying belt 18 on the lower side. The hopper 17 also serves as a frame for supporting the transfer table 4. The left and right transfer table frames 19 of the transfer table 4 are fixed to the upper position of the hopper 17 on the bucket conveyor 5 side, and the hopper 17 below the transfer table 4 is fixed. The portion serves as the collection unit 20 of the supply / collection return device 16.
Further, the hopper 17 is formed in an open stretched portion 21 that protrudes a predetermined length longer to the side than the side opposite the bucket conveyor 5 of the transfer table 4 and does not overlap with the transfer table 4. It is preferable that the tensioning portion 21 is provided with an opening having a size that allows soil to be stretched by a forklift 22 or the like, because the work becomes easy.
[0008]
And the terminal (bucket conveyor 5) side of the hopper 17 is connected to the lower part of the bucket conveyor 5 so that the bucket 6 can receive soil.
Reference numeral 23 denotes a driving roller of the conveyor belt 18, and 24 denotes a passive roller of the conveyor belt 18.
Thus, an induction rod 25 is provided on the upper portion of the bucket conveyor 5. The guide rod 25 is connected to the discharge port 26 of the bucket conveyor 5 to connect the connecting portion 27 inclined downward toward the transfer table 4 and the soil 3 radiated in the direction intersecting the transfer direction of the transfer table 4 to the transfer table 4. It is formed by a guide portion 28 that is parallel to the transfer direction and is guided to the start end side of the transfer table 4. The guide portion 28 is positioned substantially above the center of the left and right of the transfer table 4.
The transfer table 4 is provided with transfer means 30 for transferring the seedling raising container 2 in the transfer table frame 19, and a scraper 31 is provided above the transfer means 30 and in front of the guide rod 25 in the transfer direction. The scraper 31 is formed of an elastic member such as a V-shaped rubber having a center in the rear in the plan view and a front side in the left and right sides. The scraper 31 is attached to a pair of left and right support columns 32 provided on the transfer table 4 so as to be adjustable in height. Further, when the amount of soil supplied by the bucket conveyor 5 is particularly large, the scrapers 31 may be arranged in front and rear.
[0009]
A rotating brush 33 is provided on the front side of the scraper 31 to sweep the upper surface of the soil supplied to the seedling raising container 2. The rotating brush 33 has a known configuration, and although not shown in the drawings, the rotating brush 33 is mounted on the distal ends of a pair of left and right arms, is driven to rotate, and is attached so as to be adjustable in height by a height adjusting device provided on the arms.
Thus, the transfer table 4 is provided with a pair of left and right guide and upright members 36 for guiding the seedling raising container 2. That is, the seedling container 2 is composed of a so-called drawer-shaped seedling box whose upper surface is not shown, although not shown, or one in which a pot 38 is fitted to a frame 37, and the seedling container 2 is transferred to a transfer stand. 4, the side portions of the seedling box and the frame 37 are brought into sliding contact with the guide / standing member 36 to guide the transfer of the seedling raising container 2, and the upper end of the guide / standing member 36 is a seedling box The storage space 40 is formed by the left and right guide and upright members 36 and the upper surface of the seedling container 2, and the soil intermittently supplied by the bucket conveyor 5 is stored in the storage space 40. Thus, expecting the action of the hopper, firstly supplying more soil than necessary and sufficient amount, and then removing the excess soil by the scraper 31 to set the supply amount to the set amount.
[0010]
Therefore, the guide and upright member 36 is formed of a vertical plate, and the start end portion is positioned on the rear side with a predetermined interval from the guide rod 25 of the bucket conveyor 5, and the end portion (front end portion) of the guide and upright member 36 is It arrange | positions so that the clearance gap 41 in which soil may fall may be formed between the said scrapers 31 (Scraper 31 in front when multiple scrapers 31 are arranged in parallel). Further, if the guide and upright member 36 is attached to the frame 19 so that the left and right width and height can be adjusted, it is possible to correspond to the seedling container 2 having different sizes, which is preferable (FIG. 4).
Accordingly, the hopper 17 of the supply / recovery device 16 is formed in a V shape when viewed from the side so that the soil falling from the transfer table 4 can be recovered. It is preferable that the rear plate 43 and the rear plate 43 are positioned on the front side of the rotary brush 33 from the start end of the member 36 to the start end side of the transfer table 4, so that the soil can be reliably collected.
Further, the hopper 17 is provided with traveling wheels 44 so that the transfer table 4, the bucket conveyor 5 and the supply / collection return device 16 can be moved integrally. The traveling wheel 44 is a free wheel (caster wheel), and if it is provided with a stopper mechanism, operability and workability are improved.
[0011]
[Action]
Next, the operation will be described.
When sieving is put into the extension portion 21 of the hopper 17 of the supply / collection return device 16 and the entire switch is turned on, the supply / collection return device 16, the bucket conveyor 5 and the transfer table 4 are energized.
The sieve soil thrown into the stretched portion 21 of the hopper 17 is transported to the lower part of the bucket conveyor 5 by the transport belt 18, and the bucket 6 that reverses and rises at the end of the hopper 17 raises the soil at the upper position. After the release, the released soil is changed in the flow direction parallel to the transfer direction of the transfer table 4 by the guide rod 25 of the bucket conveyor 5 and falls above the transfer table 4.
[0012]
At this time, since the seedling container 2 is transferred to the transfer table 4, the soil that has fallen from the guide rod 25 is supplied to the seedling container 2.
In this case, the bucket conveyor 5 only drops the soil above the raising seedling container 2 being transferred, but the transfer table 4 is provided with a pair of left and right guides and standing members 36 for guiding the raising seedling container 2 being transferred. Since the combination standing member 36 is formed so as to be much higher than the upper edge of the pot 38 or the seedling box of the seedling container 2, a large amount of soil supplied from the bucket conveyor 5 is on the upper surface of the seedling container 2 and the left and right guide / standing members 36. Is stored in a storage space 40 surrounded by the scraper 31 and is set to a supply set amount when passing under the scraper 31.
[0013]
That is, instead of adjusting the feed outlet and dropping a predetermined amount of soil into the seedling container 2 as in the past, a large amount is supplied onto the seedling container 2, and then the supply set amount is set by the scraper 31. In particular, there is no soil feeding device comprising a hopper and a feeding belt above the transfer table 4, and the bucket conveyor 5 is intermittently supplied by the bucket 6, but a pair of left and right guide and upright members 36 and a scraper are provided on the transfer table 4. It is only necessary to provide 31 and the configuration can be simplified. In this case, a scraper 31 and a rotating brush 33 have been provided in the past, but this is a method of supplying and removing an extra few millimeters or 1 cm as much as possible on the soil surface, and the entire seedling container 2 Unlike a large amount supply of several centimeters or more for supplying all over, a soil feeding device that requires a hopper, a supply belt and the like cannot be omitted. Therefore, by adopting a configuration in which a large amount is supplied and removed by the scraper 31, it is possible to omit the soil feeding device including the hopper and the feeding belt.
Since it is premised on a large amount of supply, it is not necessary to set a precise supply amount, and direct supply by the bucket conveyor 5 is possible. In this respect as well, the cost can be reduced. That is, in the conventional soil feeding device, the soil outlet is only filled with a little large lump, so that the soil is not supplied from this portion, and the supply amount is uneven. Therefore, the type of soil and the opening area of the outlet are reduced. Although precise adjustment is required, in the case of the present application, since it is removed after a large amount of supply, direct supply by the bucket conveyor 5 becomes possible, and operability and workability are improved.
[0014]
In addition, the bucket conveyor 5 releases the soil in a direction intersecting the transfer direction of the transfer table 4, but the guide rod 25 provided on the upper portion of the bucket conveyor 5 changes the flow direction parallel to the transfer direction. Therefore, the soil can flow down to the left and right sides above the seedling container 2, and by the synergistic action with the guide rod 25, the pot 3 type seedling container 2 can reliably supply the soil to each pot 38.
Thus, the transfer table 4 is mounted and fixed on the hopper 17 of the supply / recovery device 16 at the front and rear central portions of the transfer table frame 19, and the front plate 42 and the rear plate 43 of the hopper 17 are connected to the transfer table 4. Since it is provided in the range where the soil falls more, the surplus soil out of the soil supplied to the seedling container 2 by the transfer stand 4 falls into the collection unit 20 of the hopper 17 of the supply and recovery unit 16 and is stuck. It joins with the soil and is supplied to the seedling raising container 2 by the bucket conveyor 5.
[0015]
Therefore, a large amount of soil is supplied to the seedling container 2 and a large amount of soil is dropped, but by combining the supply and recovery unit 16 with the bucket conveyor 5, the operation can be continued and the operation can be simplified. In addition, the transfer table 4 can be configured without any special support legs, and the number of parts can be reduced.
However, since the amount of soil raised by the bucket conveyor 5 and the amount of soil supplied to the seedling raising container 2 cannot be completely matched, conventionally, complicated control is performed, and therefore the structure is also complicated. However, the bucket conveyor 5 is set to be slightly larger than the supply amount to the seedling container 2, and the excess soil is dropped and circulated to the hopper 17 of the supply and recovery unit 16 so that the configuration can be improved. It is simple and the number of parts can be reduced.
[0016]
Therefore, the hopper 17 is formed in the open tension part 21 that protrudes a predetermined length from the side opposite to the bucket conveyor 5 of the transfer table 4 and has an upper surface that does not overlap with the transfer table 4. Since the soil can be put in 21 with a forklift 22 or the like, the work can be facilitated, and it is not necessary to provide a supply hopper at the lower part of the bucket conveyor 5, the number of parts can be reduced, the cost can be reduced, and the maintenance portion can be reduced. It is possible and suitable.
