Floats (side floats) 14 and 14 for leveling while sliding on the seedling planting surface, a center float 14S, and the like are provided.

整地ロータ８は、昇降可能なロータ支持フレーム１９に回転自在に架設してあり、畦クラッチレバー２０近くに配置されたロータ高さ調節レバー２１の操作によって非接地状態と接地状態とに上げ下げできる構成になっている。ロータ高さ調節レバー２１の上げ下げ操作で、整地ロータ８は昇降ロッド２６、昇降アーム２７、ケーブル２８等を介して昇降する。また、この整地ロータ８は、ロータ駆動モータ２２によって駆動する構成であり、接地状態で回転駆動することにより代掻き整地する構成としている。   The leveling rotor 8 is rotatably mounted on a rotor support frame 19 that can be raised and lowered, and can be raised and lowered to an ungrounded state and a grounded state by operating a rotor height adjusting lever 21 disposed near the saddle clutch lever 20. It has become. By the raising / lowering operation of the rotor height adjusting lever 21, the leveling rotor 8 moves up and down via the lifting rod 26, the lifting arm 27, the cable 28, and the like. Further, the ground leveling rotor 8 is configured to be driven by the rotor drive motor 22, and is configured to perform ground leveling by rotationally driving in a grounded state.

副変速レバー１８は、図３に示すように、走行速度の速い路上走行速（移動速）Ｈと、走行速度の遅い作業速（ＰＴＯ）Ｌと、苗植付部のみを作動させる植付部駆動速Ｐとに切替可能に構成してあり、路上走行速Ｈでは、整地ロータ８、苗植付部６共に停止状態とし、作業速（特に枕地での作業速）Ｌでは、整地ロータ８、苗植付部６共に駆動する状態とし、植付部駆動速Ｐでは、整地ロータ８は停止状態とすると共に苗植付部６のみ駆動する状態となるよう副変速レバー１８の切替操作に連動して整地ロータ８及び苗植付部６の駆動を入切する構成としている。   As shown in FIG. 3, the auxiliary transmission lever 18 includes a road traveling speed (moving speed) H having a high traveling speed, a working speed (PTO) L having a low traveling speed, and a planting section that operates only the seedling planting section. It can be switched to the driving speed P. At the road traveling speed H, both the leveling rotor 8 and the seedling planting portion 6 are stopped, and at the working speed (especially the working speed at the headland) L, the leveling rotor 8 The seedling planting unit 6 is driven to be driven, and at the planting unit driving speed P, the leveling rotor 8 is stopped and only the seedling planting unit 6 is driven. Thus, the driving of the leveling rotor 8 and the seedling planting unit 6 is turned on and off.

When the leveling rotor 8 detects the ascending non-grounding state, the rotor driving motor 22 is driven. It is configured to be linked to stop.

次に苗植付具の構成例について説明する。
苗植付具１２の植付爪３０（図６〜図１５）において、該爪３０の背面３０ａの部分で植付フォーク３１がスライドする先端側の一定範囲Ｌ間（図６及び図８参照）を、略同幅でストレートに最大幅をもたせ、且つ、平坦で薄くし、そして、その一定範囲Ｌ間より後方で苗に接触しない部分からは徐々に丸み３０ｂをもたせて太くした構成とする。これによって、苗の分離性が良くなり、爪自体の剛性もより確保することができる。 Next, a configuration example of the seedling planting tool will be described.
In the planting claw 30 (see FIGS. 6 to 15) of the seedling planting tool 12, between the fixed range L on the tip side where the planting fork 31 slides at the back surface 30 a of the claw 30 (see FIGS. 6 and 8). Is made straight and has the maximum width straight, flat and thin, and gradually thickened from the portion that does not come into contact with the seedlings behind the fixed range L and gradually thickens. As a result, the separation of seedlings is improved, and the rigidity of the nail itself can be further ensured.

また、植付爪３０は、フォーク３１が通過する背面３０ａ部分よりこの背面側下方に向けて徐々に肉厚ｔを厚くして断面係数を大きくしている。これによれば、爪の正面（前面）側上方への盛り上がりが少なくなるため、分離抵抗が少なくなり、分離性能が向上する。   Further, the planting claw 30 gradually increases the wall thickness t from the back surface 30a portion through which the fork 31 passes toward the lower side of the back surface to increase the section modulus. According to this, since the rising of the nail to the front (front side) side is reduced, the separation resistance is reduced and the separation performance is improved.

更に、植付爪３０のパーティングラインＰｌは、図６に示すようになり、爪背面３０ａ部分でＬ間隔範囲内での苗を分離する部分Ｄ幅（図８及び図１４参照）が最も広くなり、その広い部分より後方ではラインＰｌが植付爪中央まで上がっていくようになっている。そのため、苗の分離が容易となり、苗にやさしく作用することになる。また、図１４（ロ）に示すように、植付爪３０の先端形状において、先端Ｑより内側は肉薄で半径Ｒ１が大きく、外側は半径Ｒ２が小さくなるように構成している。分離爪先端の内側では、苗の分離がし易くなり、外側ではＲ２抵抗が大きいため、左右外側方向へは拡がりにくくなり、強度的に安定した植付爪が得られる。   Further, the parting line Pl of the planting claw 30 is as shown in FIG. 6, and the part D width (see FIGS. 8 and 14) for separating the seedlings within the L interval range at the claw back surface 30a is the widest. The line Pl goes up to the center of the planting claw behind the wide part. Therefore, the separation of the seedling is facilitated, and the seedling acts gently. Further, as shown in FIG. 14B, the tip shape of the planting claw 30 is configured such that the inside of the tip Q is thin and the radius R1 is large, and the radius R2 is small on the outside. The inside of the tip of the separation claw makes it easy to separate the seedlings, and since the R2 resistance is large on the outside, it is difficult to spread in the left and right direction, and a planting claw that is stable in strength can be obtained.

図１６に示す実施例は、苗載台１１が左右に往復移動して苗載台上のマット苗を苗載台下端側の苗受枠３４に設けられた苗取出口３５側へ一株づつ順次供給し、それを苗植付具の植付爪３０が分離して取り出し下方へ移送して圃場に植え付ける構成のものにおいて、苗受枠３４における苗取出口３５の裏面側左右部位から適宜下方にわたる部位には、苗植付爪３０によって圃場の植付位置へ移送される苗を苗植付爪３０から左右方向へ逸脱しないように案内する樹脂等で成形された一対の苗ガイド板３６，３６が設けられている。苗ガイド板３６，３６と一体で苗取出口３５の上部に位置するスペーサ部３７を植付爪の作動軌跡ギリギリまで下げると共に、植付爪と干渉する部分には下向きの切欠凹部３８を設ける。苗取り量を少なくすると、取出口３５上部との隙間が大きくなり、苗の連れ出しが増加するが、取出口上部を取り量最大時のギリギリまで下げることで、隙間を従来のものより大幅に狭くすることができ、苗の連れ出しが減少する。   In the embodiment shown in FIG. 16, the seedling mounting table 11 reciprocates left and right, and the mat seedlings on the seedling mounting table are sequentially transferred one by one to the seedling outlet 35 provided on the seedling receiving frame 34 on the lower end side of the seedling mounting table. In the structure in which the planting claw 30 of the seedling planting device is separated, taken out, transferred downward, and planted in the field, the site extends from the left and right side of the back side of the seedling outlet 35 in the seedling receiving frame 34 to the lower side as appropriate. A pair of seedling guide plates 36, 36 formed of resin or the like for guiding seedlings transferred to the planting position in the field by the seedling planting claws 30 so as not to deviate from the seedling planting claws 30 in the left-right direction. Is provided. The spacer portion 37 that is integrated with the seedling guide plates 36 and 36 and is positioned at the upper portion of the seedling extraction outlet 35 is lowered to the limit of the operation locus of the planting claw, and a downward notch recess 38 is provided in a portion that interferes with the planting claw. If the amount of seedlings is reduced, the gap between the upper part of the take-out port 35 increases and the taking-out of seedlings increases. However, by lowering the upper part of the take-out port to the limit at the time of taking the maximum amount, the gap is significantly narrower than the conventional one. Can be reduced, and seedling removal is reduced.

また、図１７に示すように、受枠３４の苗取出口３５部にプレート状で段差のあるシャッター４０を取り付け、そして、シャッター４０は、複数段の段差４０ａ，４０ｂ…の分だけ移動させる構成とし、苗取り調節の位置に合わせてシャッターを左右に移動させることにより、取出口上部の隙間を適正に補正することができ、上記の実施例（図１６）と同様に苗の連れ出しを最小限に抑制することができる。なお、シャッター４０は取付ボルト４２により取付穴４１，４１の取付位置を変更することによってスライド調節する。   In addition, as shown in FIG. 17, a plate-like shutter 40 having a step is attached to the seedling outlet 35 of the receiving frame 34, and the shutter 40 is moved by a plurality of steps 40a, 40b,. By moving the shutter to the left and right according to the position of the seedling removal adjustment, the gap at the upper part of the outlet can be corrected appropriately, and the takeout of seedlings can be minimized as in the above embodiment (FIG. 16). Can be suppressed. The shutter 40 is slid and adjusted by changing the mounting positions of the mounting holes 41 and 41 by means of mounting bolts 42.

図１８、図１９に示す実施例では、苗受枠３４内にシャッター４０を内臓し、そして、そのシャッター４０は苗取り量調節に関係なく固定された不動の支持部材に取り付ける構成としている。通常は苗取り量調節を行うと苗取出口３５上部と植付爪３０との隙間が変化し、隙間が大きくなると苗の連れ出しが多発するが、本例では隙間を一定に保持することができるので、苗取り量が安定し、苗の連れ出しを少なくすることができる。   In the embodiment shown in FIGS. 18 and 19, a shutter 40 is built in the seedling receiving frame 34, and the shutter 40 is attached to a fixed support member that is fixed regardless of the amount of seedling removal. Normally, when the amount of seedling is adjusted, the gap between the upper portion of the seedling outlet 35 and the planting claw 30 changes, and when the gap becomes larger, the seedling is frequently taken out, but in this example, the gap can be kept constant. Therefore, the amount of seedlings can be stabilized and the taking-out of seedlings can be reduced.

また、図２０、図２１に示す実施例では、前記プレート状のシャッターに代えて切欠面４４ａを施した円形状のシャフト４４を使用し、苗受枠３４の苗取出口３５直後に配置し、苗取り量を変更調節すると、切欠きシャフト４４が連動して回転するように構成している。苗取り量を変えると取出口が上下し取出口の面積が変化するが、本例の構成によれば、苗取り量を変えても取出口の面積が変わらなくなり、不必要な苗を取らなくなる。しかも、切欠きシャフトの回転であるため、プレート状シャッターのスライド構成に比べて泥や根が絡みにくくなる効果ある。   20 and FIG. 21, in place of the plate-shaped shutter, a circular shaft 44 with a cut-out surface 44a is used, which is arranged immediately after the seedling outlet 35 of the seedling receiving frame 34. When the amount of change is changed and adjusted, the notch shaft 44 is configured to rotate in conjunction with it. If the amount of seedlings is changed, the take-out port will rise and fall, and the area of the take-out port will change. . In addition, since the rotation of the notch shaft, mud and roots are less likely to be entangled compared to the slide configuration of the plate shutter.
