このとき、畦案内ローラ64からアーム65の回動支点65aまでのアーム65の長さL1と前輪6の車軸17から回動支点65aまでのアーム72の長さL2をほぼ同一長さとする。このために後輪7を中心に苗植機全体の操舵方向の修正が円滑に行え、畦案内ローラ64と前輪6にバランスよく操舵時の負荷がかかる。   At this time, the length L1 of the arm 65 from the saddle guide roller 64 to the rotation fulcrum 65a of the arm 65 and the length L2 of the arm 72 from the axle 17 of the front wheel 6 to the rotation fulcrum 65a are substantially the same length. For this reason, the steering direction of the entire seedling transplanter can be corrected smoothly with the rear wheel 7 as the center, and the load during steering is applied to the heel guide roller 64 and the front wheel 6 in a well-balanced manner.

また、後輪7の車軸10上に補助苗枠77の支持アーム79を立てている。こうすると補助苗枠77内に補給する苗の量に変動があっても苗植機全体の重心の変動を小さくすることができる。
また、ボンネット69の上部に座席23を設け、苗供給装置32との間に足を乗せる平面状のステップ70を設けているので補助苗枠内に苗を補給する作業がし易くなる。ステップ70のボンネット69の側方となる前半分は低くしても良い。
A support arm 79 of the auxiliary seedling frame 77 is erected on the axle 10 of the rear wheel 7. In this way, even if the amount of seedlings to be replenished in the auxiliary seedling frame 77 varies, the variation in the center of gravity of the entire seedling transplanter can be reduced.
In addition, since the seat 23 is provided at the upper part of the bonnet 69 and the flat step 70 for placing a foot between the seedling supply device 32 is provided, it is easy to replenish the seedling in the auxiliary seedling frame. The front half on the side of the bonnet 69 in step 70 may be lowered.

図3に本実施例の変形例である苗植機の平面図を示す。
図3に示すように後輪7をチェーン伝動ケース9の内側に付け替えることができ、前輪6は回動支点65aを軸心とするリンク部材72の揺動でスライド可能にし、畦案内ローラ64を横アーム65への取付位置を変えることで、幅の小さな畝Uの2条植の構成(外側2条分は使用しない)に変えることができる。
なお、前記後輪7のチェーン伝動ケース9の内側への付け替えは、チェーン伝動ケース9の左右両側に突出している車軸に後輪7を付け替えることで容易に行える。
FIG. 3 shows a plan view of a seedling planting machine which is a modification of the present embodiment.
As shown in FIG. 3, the rear wheel 7 can be changed to the inside of the chain transmission case 9, and the front wheel 6 can be slid by the swing of the link member 72 having the rotation fulcrum 65a as an axis, and the saddle guide roller 64 is By changing the mounting position on the horizontal arm 65, it is possible to change the configuration to a double row planting of the small ridges U (the outer two portions are not used).
The rear wheel 7 can be easily replaced on the inner side of the chain transmission case 9 by replacing the rear wheel 7 with the axle protruding from the left and right sides of the chain transmission case 9.

また、畦案内ローラ64がなく、サイドクラッチ及び前輪6の操舵を行うペダル73を備えた乗用型の苗植機の構成について図4の側面図と図5の平面図に示す。
補助苗枠80を支持アーム83を介してハンドル2の左右に一対設け、ハンドル2は上下回動可能とし、また座席23の下部の左右にサイドクラッチにより前輪6の操舵を行うペダル73を設けている。この苗植機は苗植付装置28の全体を覆うカバー81を設けている。
Moreover, the side view of FIG. 4 and the top view of FIG. 5 show the configuration of a riding type seedling transplanter that does not have the heel guide roller 64 and includes a side clutch and a pedal 73 that steers the front wheel 6.
A pair of auxiliary seedling frames 80 are provided on the left and right sides of the handle 2 via the support arm 83, the handle 2 can be turned up and down, and pedals 73 for steering the front wheels 6 by side clutches are provided on the left and right sides of the lower portion of the seat 23. Yes. This seedling planting machine is provided with a cover 81 that covers the entire seedling planting device 28.
