From the planting secondary shaft 53 to the seedling planting device 3 via the bevel gears G19 and G20 and the planting part transmission shaft 58. Power is transmitted. In addition, you may comprise so that the power shifted with the transmission from the planting secondary shaft 53 may be transmitted to the planting part transmission shaft 58.

次に、図７に基づき変速レバー９０と各変速ギヤとの噛み合い関係について説明する。
変速レバー９０のガイド溝９１は図７（Ａ）に示すように、機体の左右方向に変速レバー９０を操作して変速ギヤＧ３、ギヤＧ４を移動させる横溝９１ａと、油圧無段変速装置ＨＳＴを前進側に増速操作する前方縦溝９１ｂ，９１ｃ，９１ｄ、及び、油圧無段変速装置ＨＳＴを後進側に増速操作する後方縦溝９１ｅから構成されている。 Next, the meshing relationship between the transmission lever 90 and each transmission gear will be described with reference to FIG.
As shown in FIG. 7A, the guide groove 91 of the transmission lever 90 includes a lateral groove 91a that moves the transmission gear G3 and the gear G4 by operating the transmission lever 90 in the left-right direction of the machine body, and a hydraulic continuously variable transmission HST. It consists of front vertical grooves 91b, 91c, 91d for speed-up operation on the forward side, and a rear vertical groove 91e for speed-up operation of the hydraulic continuously variable transmission HST on the reverse side.

図７（Ｂ）に示すように、変速レバー９０を横溝９１ａのＡ位置に操作したときには、シフタ５６により変速ギヤＧ３、ギヤＧ４が移動されて、変速ギヤＧ３とギヤＧ５とが噛み合い、ギヤＧ４とギヤＧ７とは噛み合わない。即ち、低速の作業速度で植付部伝動軸５８は非駆動状態となり、変速レバー９０をＡ位置から後方縦溝９１ｅに沿って後側に操作すると、油圧無段変速装置ＨＳＴはニュートラルから後進速度が増速変速されて機体は後進する。なお、この状態では植付部伝動軸５８は非駆動状態であるから苗植付装置３及び施肥装置４は作動しない。   As shown in FIG. 7B, when the speed change lever 90 is operated to the A position of the lateral groove 91a, the speed change gear G3 and the gear G4 are moved by the shifter 56, and the speed change gear G3 and the gear G5 are engaged with each other. And the gear G7 do not mesh with each other. That is, the planting portion transmission shaft 58 is in a non-driven state at a low work speed, and when the shift lever 90 is operated rearward along the rear vertical groove 91e from the position A, the hydraulic continuously variable transmission HST is moved from the neutral to the reverse speed. Is increased and the aircraft moves backward. In this state, since the planting part transmission shaft 58 is not driven, the seedling planting device 3 and the fertilizer application device 4 do not operate.

また、図７（Ｃ）に示すように、変速レバー９０を横溝９１ａのＢ位置に操作すると、シフタ５６により変速ギヤＧ３、ギヤＧ４が移動されて、変速ギヤＧ３とギヤＧ５、ギヤＧ７とが噛み合い、ギヤＧ６とは噛み合わない。しかして、低速の作業速度で植付部伝動軸５８が駆動状態となり、変速レバー９０をＢ位置から前方縦溝９１ｂに沿って前側に操作すると、油圧無段変速装置ＨＳＴはニュートラルから前進速度が増速変速されて機体は前進する。なお、この状態では植付部伝動軸５８は駆動状態であるから、苗植付装置３及び施肥装置４が作動して苗植付作業及び施肥作業が同時になされる。   Further, as shown in FIG. 7C, when the shift lever 90 is operated to the B position of the lateral groove 91a, the shift gear G3 and the gear G4 are moved by the shifter 56, and the shift gear G3, the gear G5, and the gear G7 are moved. Engagement, but not meshing with the gear G6. Accordingly, when the planting portion transmission shaft 58 is driven at a low work speed and the shift lever 90 is operated forward from the B position along the front vertical groove 91b, the hydraulic continuously variable transmission HST has a forward speed from neutral. The aircraft moves forward with the increased speed. In this state, since the planting part transmission shaft 58 is in a driving state, the seedling planting device 3 and the fertilizer application device 4 are operated, and the seedling planting operation and the fertilization operation are simultaneously performed.

また、図７（Ｄ）に示すように、変速レバー９０を横溝９１ａのＣ位置に操作すると、シフタ５６により変速ギヤＧ３、ギヤＧ４が移動されて、変速ギヤＧ３とギヤＧ７とが噛み合い、ギヤＧ４とギヤＧ６とは噛み合わない。しかして、低速の作業速度で植付部伝動軸５８が駆動状態となり、変速レバー９０をＣ位置から前方縦溝９１ｃに沿って前側に操作すると、油圧無段変速装置ＨＳＴはニュートラルから前進速度が増速変速されて機体は停止したままで、植付部伝動軸５８の駆動速度が増速される。即ち、苗植付装置３及び施肥装置４のみを作動させることができる。   Further, as shown in FIG. 7D, when the transmission lever 90 is operated to the C position of the lateral groove 91a, the transmission gear G3 and the gear G4 are moved by the shifter 56, and the transmission gear G3 and the gear G7 are engaged with each other. G4 and gear G6 do not mesh. Accordingly, when the planting portion transmission shaft 58 is in a driving state at a low work speed and the shift lever 90 is operated forward from the C position along the front vertical groove 91c, the hydraulic continuously variable transmission HST has a forward speed from the neutral position. The driving speed of the planting portion transmission shaft 58 is increased while the body is stopped after the speed change. That is, only the seedling planting device 3 and the fertilizer application device 4 can be operated.

また、図７（Ｅ）に示すように、変速レバー９０を横溝９１ａのＤ位置に操作すると、シフタ５６により変速ギヤＧ３、ギヤＧ４が移動されて、すべての変速ギヤＧ３，ギヤＧ４，ギヤＧ５、ギヤＧ６、ギヤＧ７は噛み合わない。即ち、機体は停止し苗植付装置３及び施肥装置４も駆動されない状態となる。   Further, as shown in FIG. 7E, when the transmission lever 90 is operated to the D position of the lateral groove 91a, the transmission gears G3 and G4 are moved by the shifter 56, and all the transmission gears G3, G4 and G5 are moved. The gears G6 and G7 do not mesh. That is, the aircraft is stopped and the seedling planting device 3 and the fertilizer application device 4 are not driven.

最後に、図７（Ｆ）に示すように、変速レバー９０を横溝９１ａのＥ位置に操作すると、シフタ５６により変速ギヤＧ３、ギヤＧ４が移動されて、変速ギヤＧ４とギヤＧ６とが噛み合い、ギヤＧ３，ギヤＧ５，ギヤＧ７とは噛み合わない。しかして、高速の路上等の移動速度に変速されて、植付部伝動軸５８は非駆動状態となり、変速レバー９０をＥ位置から前方縦溝９１ｄに沿って前側に操作すると、油圧無段変速装置ＨＳＴはニュートラルから前進速度が増速変速されて機体は高速で前進する。なお、植付部伝動軸５８は非駆動状態であるので、苗植付装置３及び施肥装置４は作動しない。   Finally, as shown in FIG. 7F, when the transmission lever 90 is operated to the E position of the lateral groove 91a, the transmission gear G3 and the gear G4 are moved by the shifter 56, and the transmission gear G4 and the gear G6 are engaged. It does not mesh with gear G3, gear G5, and gear G7. Thus, the planted portion transmission shaft 58 is shifted to a high speed on the road or the like so that the planting portion transmission shaft 58 is not driven, and when the shift lever 90 is operated forward from the E position along the front vertical groove 91d, In the apparatus HST, the forward speed is increased from the neutral position, and the aircraft advances at a high speed. In addition, since the planting part transmission shaft 58 is in a non-driven state, the seedling planting device 3 and the fertilizer application device 4 do not operate.

また、ミッションケース１１の後部には、左右のフロントアクスル６０，６０の中央部が支承され、前記走行二次軸５１からギヤＧ６とギヤＧ２１により動力が伝動され、デフ装置Ｄ１を介して左右の前輪６，６が駆動される構成である。   Further, at the rear part of the transmission case 11, the central portions of the left and right front axles 60, 60 are supported, and the power is transmitted from the traveling secondary shaft 51 by the gear G6 and the gear G21. The front wheels 6 and 6 are driven.

Then, the case can be reduced in weight.

また、左右のオイルタンク部１１ｄ，１１ｄの分割面１１ｂとミッションケース部１１ｅ，１１ｅの分割面１１ｂに接着剤用の溝７７を設け、接着剤を注入して接合固着すると、接着剤のはみ出しを防止し、オイルの漏れや汚れを防止できる。なお、接着剤用の溝７７をケースの外周分割面７８ａにのみ設け、幅狭の内周部分割面７８ｂには省略すると、構成を簡素化することができる。   In addition, an adhesive groove 77 is provided on the split surface 11b of the left and right oil tank portions 11d and 11d and the split surface 11b of the mission case portions 11e and 11e, and when the adhesive is injected and bonded and fixed, the adhesive protrudes. Prevent oil leakage and dirt. The configuration can be simplified if the groove 77 for the adhesive is provided only on the outer peripheral dividing surface 78a of the case and is omitted from the narrow inner peripheral dividing surface 78b.

また、左右のオイルタンク部１１ｄ，１１ｄ及びミッションケース部１１ｅ，１１ｅに同じ種類のオイルを注入するようにすると、メンテナンスを容易化できる。また、ミッションケース１１の左右一側のケース半体１１ａにのみオイルタンク部１１ｄを設けた構成にすると、構成を簡素化できる。   Further, maintenance can be facilitated by injecting the same type of oil into the left and right oil tank portions 11d and 11d and the mission case portions 11e and 11e. Further, if the oil tank portion 11d is provided only in the case half 11a on the left and right sides of the mission case 11, the configuration can be simplified.

また、前方の伝動軸の軸架されないオイルタンク部１１ｄにステアリング軸１４やピットマンアーム軸２６を上方に向けて突設する構成であるので、ステアリング軸１４やピットマンアーム軸２６の設計の自由度を高めることができる。また、図１１に示すように、ミッションケース１１のオイルタンク部１１ｄ，１１ｄの例えば右側前部を機体の中心線から左側に突出させた突出部１１ｇに構成し、ミッションケース部１１ｅ，１１ｅの後部右側面に油圧無段変速装置ＨＳＴを取り付けるように構成すると、左右のバランスを良くし、水田走行用機体として優れた走行性を発揮し、植付作業を良好に行なうことができる。   In addition, since the steering shaft 14 and the pitman arm shaft 26 protrude upward from the oil tank portion 11d on which the front transmission shaft is not mounted, the degree of freedom in designing the steering shaft 14 and the pitman arm shaft 26 is increased. Can be increased. Also, as shown in FIG. 11, for example, the right front part of the oil tank parts 11d, 11d of the mission case 11 is configured as a projecting part 11g projecting to the left from the center line of the airframe, and the rear part of the mission case parts 11e, 11e. When the hydraulic continuously variable transmission HST is attached to the right side surface, the right and left balance is improved, excellent running performance is exhibited as a paddy field traveling body, and planting work can be performed well.
