Specifically, the axle cases 9a and 9a are extended from the front end portions of the rear wheel transmission cases 9 and 9 toward the center of the fuselage, and the axle cases 9a and 9a are rotatably attached to the left and right side portions of the transmission case 8. . The rear wheels 6 and 6 are attached to the axles 10 and 10 that protrude rearward from the rear wheel transmission cases 9 and 9. The tip of the wheel drive shaft extended from the transmission case 8 to the left and right outwards enters the rotational axis X position of the front end portion of the rear wheel transmission cases 9, 9. Driving power that has passed through the speed change transmission portion is transmitted to the transmission mechanism in the rear wheel transmission cases 9, 9. The driving power is transmitted to the axles 10 and 10 on the rear end side of the rear wheel transmission cases 9 and 9 via the transmission mechanism in the rear wheel transmission cases 9 and 9, and the rear wheels 6 and 6 are driven to rotate. It is supposed to be.

なお、アクスルケース9a,9aは、畝幅に対応して左右に伸縮調節可能に設けている。また、アクスルケース9a,9aを支持するために、アクスルケース9a,9aと略平行する状態で支持フレーム9b、9bをミッションケース8に固着していて、その支持フレーム9b、9bの外端部に固着した支持プレート9c、9cでアクスルケース9a,9aの外側部を回動自在に支持している。   Axle cases 9a and 9a are provided so that they can be expanded and contracted to the left and right according to the width of the collar. Further, in order to support the axle cases 9a and 9a, the support frames 9b and 9b are fixed to the transmission case 8 in a state of being substantially parallel to the axle cases 9a and 9a, and are attached to the outer ends of the support frames 9b and 9b. The outer portions of the axle cases 9a, 9a are rotatably supported by the fixed support plates 9c, 9c.

また、後輪伝動ケース9,9には、該後輪伝動ケース9,9の前部側を回動支点として後輪6,6を上下させるよう上下回動する駆動手段が連結している。具体的には、後輪伝動ケース9,9のミッションケース8への取付部には、上方に延びるアーム11,11を一体的に取り付けていて、これがミッションケース8に固定された昇降用油圧シリンダ12のピストンロッド先端に取り付けた連結体13の左右両側部と連結している。左右一方側(右側)は、ロッド14で連結し、他方側(左側)は、機体の傾斜に応じて伸縮作動可能な左右水平制御用油圧シリンダ15で連結している。   Further, the rear wheel transmission cases 9 and 9 are connected to driving means for rotating up and down so that the rear wheels 6 and 6 are moved up and down using the front side of the rear wheel transmission cases 9 and 9 as a rotation fulcrum.

したがって、上記構成の苗植付機により植付けする場合において、機体高さが変動して高い位置にあっても、作業者用のステップ71,71および作業用座席70,70が走行路面から一定高さに保たれ、また、姿勢修正機構によってその姿勢が略一定に維持されることから、上下変動の大きな機体にステップを取付けた場合と比較して、機体の重心位置を低く、かつ、その変動を小さく抑えるとともに、姿勢が略一定で安定性に優れるステップによって作業環境の安定化が可能となるので、苗投入作業を安全かつ効率良く行うことができる。
なお、軸支部75,75の位置は、後輪伝動ケース9,9の回動傾斜によっても上下変動の少ない範囲であれば上記同様の効果を奏することから、その限りにおいて、車軸10の位置に限定されることなく、後輪伝動ケース9,9上で車軸10位置の近傍が含まれる。
Therefore, when planting with the seedling planting machine having the above-described configuration, the steps 71 and 71 for the workers and the work seats 70 and 70 are kept at a certain height from the road surface even if the machine height fluctuates and is at a high position. The position of the center of gravity of the fuselage is low compared to the case where a step is attached to the aircraft with large vertical fluctuations, and the fluctuations are maintained. In addition, the work environment can be stabilized by the steps having a substantially constant posture and excellent stability, so that the seedling charging operation can be performed safely and efficiently.
The shaft support portions 75 and 75 have the same effect as described above as long as they are in a range where the vertical fluctuation is small due to the rotational inclination of the rear wheel transmission cases 9 and 9. Without limitation, the vicinity of the axle 10 position on the rear wheel transmission cases 9, 9 is included.

(姿勢維持機構/別例)
次に、別例の姿勢修正機構による苗植付機について説明する。以下において、前記同様の部材はその符号を付すことによって説明を省略する。
この姿勢維持機構は、苗植付機の側面図、平面図を図3、図4にそれぞれ示すように構成している。
(Attitude maintenance mechanism / another example)
Next, a seedling planting machine using another example posture correction mechanism will be described. In the following description, the same members as those described above are denoted by the same reference numerals, and description thereof is omitted.
This posture maintenance mechanism is configured such that a side view and a plan view of the seedling planting machine are shown in FIGS. 3 and 4, respectively.

上部に作業用座席70,70を取付けた座席支持脚72,72を設け、また、前輪7,7の車軸17,17を支持する支持部材である前記縦フレーム16a,16aと、後輪6,6の車軸10,10とを連結する前後に長い連結フレーム73,73を設けて姿勢維持機構を構成する。連結フレーム73,73の前端部側は、前輪7,7の車軸17,17を支持する前記縦フレーム16a,16aの内側に突出して固着したピンに回動自在の支持筒74,74を介して前後方向摺動自在に挿入させている。また、連結フレーム73,73の後端部側は、後輪6,6の車軸10,10に回動自在に取付けた軸支部75,75に一体的に固着している。従って、後輪伝動ケース9,9が下移動して後輪6,6の車軸10,10が上下しても、連結フレーム73,73および軸支部75,75は、前後の傾き変動が生じない。   Seat support legs 72, 72 having work seats 70, 70 attached to the upper portion thereof are provided, and the vertical frames 16a, 16a, which are support members for supporting the axles 17, 17 of the front wheels 7, 7, the rear wheels 6, The posture maintaining mechanism is configured by providing long connecting frames 73 and 73 before and after connecting the six axles 10 and 10. The front end portions of the connecting frames 73 and 73 are provided via support cylinders 74 and 74 that are rotatable to pins that protrude and are fixed inside the vertical frames 16a and 16a that support the axles 17 and 17 of the front wheels 7 and 7. It is inserted slidable in the front-rear direction. Further, the rear end side of the connecting frames 73 and 73 is integrally fixed to shaft support portions 75 and 75 that are rotatably attached to the axles 10 and 10 of the rear wheels 6 and 6. Therefore, even if the rear-wheel transmission cases 9 and 9 move down and the axles 10 and 10 of the rear wheels 6 and 6 move up and down, the connecting frames 73 and 73 and the shaft support portions 75 and 75 do not change in the front-rear direction. .

軸支部75,75には、座席支持脚72,72を取付けるとともにステップ71,71を取付け、座席支持脚72,72と連結フレーム73,73との間には補強ステー72a,72aを取付けることにより、走行用の後輪伝動ケース9,9が回動して後輪6,6の車軸10,10が上下しても、作業用座席70,70およびステップ71,71は前後に傾いたりすることがない。また、座席支持脚72,72は上部を屈曲してその下部軸心まわりに回動させて、作業用座席70,70を機体内側に移動可能に設けていて、これにより、移動時や格納時に作業用座席70,70を機体内側に収納させることができる。   By attaching the seat support legs 72 and 72 to the shaft support portions 75 and 75 and attaching the steps 71 and 71, and attaching the reinforcing stays 72 a and 72 a between the seat support legs 72 and 72 and the connecting frames 73 and 73. Even if the traveling rear wheel transmission cases 9 and 9 are rotated and the axles 10 and 10 of the rear wheels 6 and 6 are moved up and down, the work seats 70 and 70 and the steps 71 and 71 may be tilted back and forth. There is no. Further, the seat support legs 72 and 72 are bent at the upper part and rotated around the lower axis thereof, so that the work seats 70 and 70 can be moved to the inner side of the machine body. The work seats 70 and 70 can be stored inside the machine body.

なお、連結フレーム73,73の前端部側を装着している前記支持筒74,74を前輪7,7の車軸17,17に取付けることもできる。また、連結フレーム73,73の後端部を後輪6,6の車軸10,10を支持する支持部材である後輪伝動ケース9,9の内側に突出させた軸に回動自在に前記軸支部75,75を回動自在に取付けこともできる。更に、連結フレーム73,73の前輪7,7側の連結部は、連結フレーム73,73を、前輪の車軸17,17又は縦フレーム16a,16aに対して摺動不能且つ回動自在に連結し、連結フレーム73,73の後輪6,6側の連結部は、連結フレーム73,73を、後輪の車軸10,10又は後輪伝動ケース9,9に対して摺動自在且つ回動自在に連結する構成することもできる。   The support cylinders 74 and 74 mounted on the front end side of the connecting frames 73 and 73 can be attached to the axles 17 and 17 of the front wheels 7 and 7. Further, the rear ends of the connecting frames 73, 73 can be pivoted about a shaft projecting inside the rear wheel transmission cases 9, 9 which is a support member for supporting the axles 10, 10 of the rear wheels 6, 6. The support portions 75 and 75 can also be rotatably attached. Further, the connecting portions on the front wheels 7 and 7 side of the connecting frames 73 and 73 connect the connecting frames 73 and 73 to the front axles 17 and 17 or the vertical frames 16a and 16a in a non-slidable and rotatable manner. The connecting parts on the rear wheels 6 and 6 side of the connecting frames 73 and 73 are slidable and rotatable with respect to the axles 10 and 10 of the rear wheels or the rear wheel transmission cases 9 and 9. It can also be configured to be connected to.

このように構成すると、後輪伝動ケース9,9が下方回動して後輪6,6の車軸10,10が下降すると、後輪6,6が機体に対して相対的に前方移動するが、作業用座席70,70は機体に対して相対的に前後方向には移動しない。従って、機体を旋回させるために後輪伝動ケース9,9を回動して機体を上昇させ、そして、操縦ハンドル2を押し下げて二輪接地状態にして機体を旋回させるとき、前後方向において作業用座席70,70が後輪6,6の車軸10,10に向って接近することになるので、作業用座席70,70の重量による操縦ハンドル2の押し下げ負荷が軽減される。また、連結フレーム73,73の前輪7,7側の連結部と、連結フレーム73,73の後輪6,6側の連結部の両方ともに、連結フレーム73,73を摺動自在且つ回動自在に連結する構成とすることもできる。   With this configuration, when the rear wheel transmission cases 9 and 9 rotate downward and the axles 10 and 10 of the rear wheels 6 and 6 are lowered, the rear wheels 6 and 6 move forward relative to the airframe. The work seats 70 and 70 do not move in the front-rear direction relative to the airframe. Accordingly, when the rear wheel transmission cases 9 and 9 are rotated to turn the airframe to raise the airframe, and the steering handle 2 is pushed down to bring the two-wheel grounding state and the airframe is turned, the work seat in the front-rear direction Since 70 and 70 approach toward the axles 10 and 10 of the rear wheels 6 and 6, the load of pushing down the steering handle 2 due to the weight of the work seats 70 and 70 is reduced. Further, both of the connecting portions on the front wheels 7 and 7 side of the connecting frames 73 and 73 and the connecting portions on the rear wheels 6 and 6 side of the connecting frames 73 and 73 are capable of sliding and rotating the connecting frames 73 and 73.
