なお、上述カッコ内の符号は、図面と対照するものであるが、何ら本発明の構成を限定するものではない。   In addition, although the code | symbol in the said parenthesis contrasts with drawing, it does not limit the structure of this invention at all.

請求項１に係る本発明は、株間変速装置用開口部に臨んで、株間変速レバー挿し込み部を配置し、かつ株間変速レバーを着脱自在としたので、株間を変更する際には、株間変速レバー挿し込み部に株間変速レバーを挿し込むことで、株間変速装置用開口部より上方に突出する株間変速レバーを設けることができ、操作性を向上することができる。また、株間を変更しない通常作業時には、凹部に設けた株間変速レバー収納部に株間変速レバーを収納することができるので、該株間変速レバーが作業者にとって作業の邪魔にならず、作業性を向上することができる。また、凹部に設けられた注油部用開口部から、注油部の注油作業が可能なので、走行機体の外面に注油部を設ける必要がなくなる。また、凹部を、比較的力のかからないフロアステップ前方を覆うカバー部材に設け、かつ左右方向において注油部を株間変速レバー収納部と重なるように設けたので、凹部をコンパクトに構成して凹部を設けたことによる強度の減少の影響を抑え、作業者の脚の引っ掛かり等を低減することができる。 Since the present invention according to claim 1 faces the opening for the inter-shaft transmission, the inter-shaft gear shifting lever insertion portion is arranged and the inter-shaft gear shifting lever is detachable. By inserting the inter-company transmission lever into the lever insertion part, it is possible to provide an inter-company transmission lever that protrudes upward from the opening for the inter-transmission apparatus, and to improve operability. Also, during normal work without changing the stock, the stock shift lever can be stored in the stock shift lever storage part provided in the recess, so the stock shift lever does not interfere with the work for the operator, improving workability can do. In addition, since the lubrication part can be lubricated from the lubrication part opening provided in the recess, it is not necessary to provide the lubrication part on the outer surface of the traveling machine body. Further, a recess, relatively force provided on the cover member for covering the floor step forward not applied with, and is provided with the lubrication portion in the left-right direction so as to overlap the strains shift lever housing portion, a recess constitutes a recess in a compact suppressing the influence of reduction in strength due to the can you to reduce the snagging or the like of the operator of the legs.

請求項２に係る本発明は、株間変速レバー挿し込み部を前後方向において注油部及び変速レバー収納部に重なるように配置したので、凹部をコンパクトに構成して凹部を設けたことによる強度の減少の影響を抑え、作業者の脚の引っ掛かり等を低減することができる。 In the second aspect of the present invention, since the inter-strain shift lever insertion portion is disposed so as to overlap the lubrication portion and the shift lever storage portion in the front-rear direction, the strength is reduced by forming the recess compactly and providing the recess. Can be suppressed, and the operator's leg catches can be reduced.

請求項３に係る本発明は、株間変速レバー収納部をカバー部材と一体に成形したので、コストダウンすることができると共に、株間変速レバーを凹部内に収納したので、株間変速レバーの紛失を防止することができる。また、凹部を塞ぐ蓋部材を設けたので、株間変速レバー非操作時には、凹部から泥等の汚れが入るのを防ぐことができる。   According to the third aspect of the present invention, since the inter-shaft shift lever housing portion is formed integrally with the cover member, the cost can be reduced and the inter-shaft shift lever is housed in the recess, thereby preventing the inter-shaft shift lever from being lost. can do. In addition, since the lid member that closes the recess is provided, dirt such as mud can be prevented from entering from the recess when the inter-stock shift lever is not operated.

請求項４に係る本発明は、凹部を傾斜面に設けたので、株間変速レバー操作時及びメンテナンス時の視認性を向上することができる。   According to the fourth aspect of the present invention, since the concave portion is provided on the inclined surface, the visibility at the time of operating the inter-stock shift lever and at the time of maintenance can be improved.

Has been. The protruding portion 27 may be formed not on the cover member 26 side but on the floor step 23 side, and has an inclined surface facing the operator seated on the driver seat 17 in any case. Since the inclined surface 27a is a portion where a worker does not walk on the upper surface and does not apply a relatively strong force, even if the concave portion 28 is formed, the influence of a decrease in strength can be suppressed. A mission case 29 is disposed below the recess 28 (see FIG. 1).

エンジンから上記ミッションケース２９に入力された回転は、上記植付作業機９に伝達される植付伝動系と、上記前輪２及び後輪３に伝達される走行伝動系と、に分岐するように構成されている。上記ミッションケース２９内の上記植付伝動系は、エンジンからの回転を、複数のギヤを選択的に噛み合わせて３段階に変速する第１の株間変速装置（不図示）と、２段階に変速する第２の株間変速装置（不図示）と、を備えており、これら第１の株間変速装置と第２の株間変速装置（株間変速装置）とを組み合わせることによって、車速に対する苗の植付間隔である株間を６段階に調整することができる。   The rotation input from the engine to the mission case 29 is branched into a planting transmission system transmitted to the planting work machine 9 and a traveling transmission system transmitted to the front wheels 2 and the rear wheels 3. It is configured. The planting transmission system in the mission case 29 includes a first inter-gear transmission (not shown) that shifts the rotation from the engine in three stages by selectively meshing a plurality of gears, and a two-stage transmission.

本実施の形態は、以上のような構成からなるので、乗用型移植機１の通常作業時においては、作業者は、カバー部材２６の凹部２８に蓋部材４７で蓋をして作業をするが、該蓋部材４７は、凹部２８の縁部２８ｃ，２８ｃ（図４参照）に爪５０，５０が差し込まれた後、ノブ４９を回転して、プレート４９ａを凹部２８に掛止させることでロックする。   Since the present embodiment is configured as described above, during the normal operation of the riding type transplanter 1, the operator works by covering the concave portion 28 of the cover member 26 with the lid member 47. The lid member 47 is locked by engaging the plate 49a with the recess 28 by rotating the knob 49 after the claws 50, 50 are inserted into the edges 28c, 28c (see FIG. 4) of the recess 28. To do.

株間を変更する際には、作業者は、蓋部材４７をロックした状態からノブ４９を９０度回転して、ロックを解除する。そして、該蓋部材４７を取り外した後、株間変速レバー収納部４６に収納された株間変速レバー３６を取り出して、該株間変速レバー３６を株間変速レバー挿し込み部３７又は３９に挿し込む。この時、株間変速レバー３６は、株間変速装置用開口部２８ａから上方に所定長さ突出し、作業者が該株間変速レバー３６を握り易く、少ない力で操作することができ、操作性が良い。作業者は、上記株間変速レバー３６を傾倒操作して、支点軸３３，３５、プレート４０，４１、ピン４２，４３を介して、第１又は第２のシフタ軸３１，３２をスライドし、第１又は第２の株間変速装置を変速する。これら第１又は第２の株間変速装置の変速操作によって、エンジンからの動力が植付伝動系において変速されて植付作業機９に伝達され、株間を変更することができる。また、ミッションケース２９内に潤滑オイルを注油する際にも、蓋部材４７を取り外した状態で、注油部用開口部２８ｂを通じて、注油部４５から注油作業を行なう。   When changing between stocks, the operator rotates the knob 49 by 90 degrees from the state in which the lid member 47 is locked, and releases the lock. Then, after removing the cover member 47, the stock shift lever 36 stored in the stock shift lever housing portion 46 is taken out, and the stock shift lever 36 is inserted into the stock shift lever insertion portion 37 or 39. At this time, the stock shift lever 36 protrudes upward by a predetermined length from the stock transmission opening 28a, so that an operator can easily grip the stock shift lever 36 with a small force, and the operability is good. The operator tilts the stock shift lever 36 and slides the first or second shifter shafts 31 and 32 through the fulcrum shafts 33 and 35, the plates 40 and 41, and the pins 42 and 43. Shift the 1 or 2 inter-stock transmission. By the shifting operation of the first or second inter-strain transmission, the power from the engine is shifted in the planting transmission system and transmitted to the planting work machine 9, so that the strain can be changed. In addition, when lubricating oil is injected into the mission case 29, the lubricating operation is performed from the lubricating portion 45 through the lubricating portion opening 28b with the lid member 47 removed.

第１又は第２の株間変速装置の変速操作が終了すると、作業者は、株間変速レバー挿し込み部３７又は３９から株間変速レバー３６を引き抜いて株間変速レバー収納部４６に収納し、上述した手順で凹部２８に蓋部材４７で蓋をする。このため、株間を変更しない通常作業時には、凹部２８内に株間変速レバー３６を収納できるので、該株間変速レバー３６が作業者にとって作業の邪魔となることがなく、作業性を向上することができ、かつ株間変速レバー３６の紛失を防止することができる。また、蓋部材４７によって、凹部２８から泥等の汚れが入るのを防ぐことができる。   When the shifting operation of the first or second inter-shaft transmission device is completed, the operator pulls out the inter-shaft gear shifting lever 36 from the inter-shaft shifting lever insertion portion 37 or 39 and stores it in the inter-shaft shifting lever housing portion 46, and the procedure described above. Then, the concave portion 28 is covered with the lid member 47. For this reason, during normal work without changing between stocks, the stock shift lever 36 can be housed in the recess 28, so that the stock shift lever 36 does not interfere with the work for the operator, and workability can be improved. In addition, the loss of the inter-strain shift lever 36 can be prevented. Further, the lid member 47 can prevent dirt such as mud from entering the recess 28.

なお、第１及び第２の株間変速装置は、それぞれ３段階と２段階に変速可能とし、計６段階に株間を調整できるとしたが、これに限らず複数段階に調整できるものなら何段階としてもよく、また、株間変速装置を１つのみから構成して、１つの株間変速レバー挿し込み部及びそれと連動する部材によって株間を複数段階に調整する構成としても良い。   In addition, the first and second inter-equipment transmissions can be shifted in 3 stages and 2 stages, respectively, and the inter-stock transmission can be adjusted in a total of 6 stages. However, the present invention is not limited to this. Moreover, it is good also as a structure which comprises only a single transmission apparatus between stocks, and adjusts between stocks in multiple steps with one stock transmission lever insertion part and the member linked with it.
