Description

本発明は、コンバインや建設機械等作業車両の燃料セジメンタ配置構造に関する。 The present invention relates to a fuel segmenter arrangement structure for a work vehicle such as a combine harvester or a construction machine.

一般に、コンバイン等の機体フレームに搭載するエンジンに供給する燃料油を収容する燃料タンクは、燃料油中の水分や異物を分離する燃料セジメンタを備えて燃料供給を行うようにしている。そして、このセジメンタは貯水部の貯水限界水位の視認と溜まり水の排出作業を逐次且つ定期的に行うことにより、水混入に伴うエンジンブローを防止するようにしている。
従来、燃料供給口（給油口部）の近傍にセジメンタを配置したコンバインは、特許文献１に示されるように既に公知であり、このセジメンタは貯水部の水量を視認可能なスリットを有するカバーによって機体後部の外方から覆う構成になっている。 Generally, a fuel tank for accommodating fuel oil to be supplied to an engine mounted on an airframe such as a combine is provided with a fuel segmenter for separating water and foreign matter in the fuel oil to supply fuel. Then, this segmenter is designed to prevent engine blow due to water mixing by visually recognizing the water storage limit water level of the water storage unit and discharging the accumulated water sequentially and regularly.
Conventionally, a combine in which a combiner is arranged in the vicinity of a fuel supply port (fuel filler port) is already known as shown in Patent Document 1, and this combiner has a cover having a slit for visually recognizing the amount of water in the water storage part. It is configured to cover from the outside of the rear part.

特開２０１６−２１４０９８号公報Japanese Unexamined Patent Publication No. 2016-214098

上記特許文献１に示されるコンバインの燃料セジメンタ配置構造は、走行機体の右側後部に立って給油作業を行う位置から、大きく後方に移動することなく腰をかがめて後ろをのぞき込む動作によって、カバーのスリットからセジメンタの水量を外方から視認できる利点がある一方で、意識的な視認点検動作を要すること、及び補給油タンク（携行缶）から給油口部に給油をする給油姿勢のままではセジメンタを正確に視認できない等の欠点がある。
即ち、このコンバインで行う給油作業では、給油口部の後方に折り畳まれている給油台に重量のある補給油タンクを載せた状態で、口蓋（キャップ）を外した給油口内に燃料を注入供給する作業をしながら、セジメンタの水位量を確認することは、該セジメンタが給油口とは方向が異なる機体後部下方にあること、また補給油タンクが視界を妨げて視認動作の邪魔をするため、定期的に行われる給油作業機会を利用して、給油動作と共に水位視認動作を同時的に行うことができない等の課題がある。 The fuel combine harvester arrangement structure of the combine shown in Patent Document 1 is a slit of the cover by bending down and looking into the back from the position where the refueling work is performed by standing at the rear right side of the traveling machine body without moving significantly backward. While it has the advantage of being able to visually check the amount of water in the combine harvester from the outside, it requires a conscious visual inspection operation, and the combine harvester is accurate if the refueling posture is used to refuel the refueling port from the refueling tank (carrying can). Has drawbacks such as being invisible.
That is, in the refueling work performed by this combine, fuel is injected and supplied into the refueling port with the palate removed with the heavy refueling tank placed on the refueling table folded behind the refueling port. Checking the water level of the combine harvester while working is regularly performed because the combine harvester is located below the rear of the aircraft in a direction different from the fuel filler port, and the refueling oil tank obstructs the view and interferes with the visual operation. There is a problem that it is not possible to simultaneously perform the water level visual recognition operation together with the refueling operation by utilizing the refueling work opportunity that is performed in a specific manner.

A plurality of mounting portions (not shown) projecting from the fuel tank 8 are bolted to the fuselage frame 2 or the tank support member 2a side, and the fuel tank 8 is attached to the left and right sorting chamber side frames 24 at the rear portion of the fuselage frame 2. It is designed so that it can be easily attached and detached below the rear part.

そして、燃料タンク８の給油口部８ａは図３,図４に示すように、タンク左側面から斜め上方に一体的に延出する給油管２６を、前記タンク隔壁２５に形成される隔壁開口部２７を通して外方上方に向けて突出させ、これにより給油高さ位置にした給油管２６の管端の給油口に対し、口蓋（キャップ）２６ａを着脱自在に取付けて構成している。
この給油口部８ａは、前記選別室側枠２４の後部側を覆う単一の給油口カバー１１によって、給油管２６の口蓋２６ａを開口部１１ａから突出させることなく覆われ、且つ給油口カバー１１の開口部１１ａに設けられる開口カバー２８を介し口蓋２６ａの開閉を可能にしている。 Then, as shown in FIGS. 3 and 4, the fuel filler port 8a of the fuel tank 8 has a partition wall opening formed in the tank partition wall 25, which is an oil supply pipe 26 that integrally extends diagonally upward from the left side surface of the tank. The palate (cap) 26a is detachably attached to the refueling port at the end of the refueling pipe 26 which is projected outward and upward through the 27 and thereby at the refueling height position.
The fuel filler port 8a is covered by a single fuel filler port cover 11 that covers the rear side of the sorting chamber side frame 24 without projecting the palate 26a of the fuel filler pipe 26 from the opening 11a, and the fuel filler port cover 11 is covered. The palate 26a can be opened and closed via the opening cover 28 provided in the opening 11a.

次に、図２,図３,図４を参照しタンク隔壁２５とセジメンタ１０の配置構造及び給油口カバー１１について説明する。先ず、タンク隔壁２５は図３（ｂ）に示すように、略三角形状で起立する隔壁本体をなす隔壁板２５ａの下側辺と後側辺と上側辺とのそれぞれに、各対向する機体フレーム２と排藁処理部４ａと選別室側枠２４のフランジ面と面接当可能な取付片（フランジ部）２５ｂを外向きリブ状に屈曲形成している。 Next, the arrangement structure of the tank partition wall 25 and the segmenter 10 and the fuel filler port cover 11 will be described with reference to FIGS. 2, 3, and 4. First, as shown in FIG. 3B, the tank partition wall 25 has a body frame that faces each of the lower side, the rear side side, and the upper side of the partition wall plate 25a forming the partition wall body that stands up in a substantially triangular shape. The mounting piece (flange portion) 25b that can be contacted with the flange surface of the straw waste processing portion 4a, the sorting chamber side frame 24, and the sorting chamber side frame 24 is bent and formed in an outward rib shape.

これによりタンク隔壁２５は、下側辺の取付片２５ｂが機体フレーム２に、上側辺の取付片２５ｂが選別室側枠２４にボルト固定される。これにより強固に立設されるタンク隔壁２５は、雑草や泥土等の飛散物がタンク側へ侵入することを遮ることができる。
またタンク隔壁２５の隔壁板２５ａは、前記給油管２６を通す隔壁開口部２７を下側辺の前部側から上方に向けて下向きＵ字状の切欠孔を形成するに、隔壁開口部２７の後方を広幅板面となし、該広幅板面の外方側にセジメンタ１０を給油管２６の後方側で略同高さ位置に安定よく取付けできる剛体構造の取付け部材にしている。 As a result, in the tank partition wall 25, the mounting piece 25b on the lower side is bolted to the machine frame 2, and the mounting piece 25b on the upper side is bolted to the sorting chamber side frame 24. As a result, the tank partition wall 25 that is firmly erected can prevent scattered materials such as weeds and mud from entering the tank side.
Further, the partition plate 25a of the tank partition wall 25a forms a downward U-shaped notch in the partition wall opening 27 through which the oil supply pipe 26 is passed from the front side of the lower side toward the upper side. The rear side is a wide plate surface, and the sequencer 10 is provided on the outer side of the wide plate surface as a rigid body structure mounting member that can be stably mounted at substantially the same height position on the rear side of the refueling pipe 26.

即ち、実施形態のタンク隔壁２５は、隔壁板２５ａの広幅板面の外周側にリブ状の取付片２５ｂを一連に形成しているため、軽量化を指向した肉薄鉄板を使用しながらセジメンタ１０を剛性を有して取付支持することができ、また図３（ｂ）で示すように広幅板面と取付片２５ｂとの適所に断面Ｌ字状の取付座２５ｃの両端部を接合して剛体構造にする。そして、取付座２５ｃは、その外方を向く平坦状の座面にネジ孔を形成しており、該座面にセジメンタ１０を上部側の支持ケース１０ａに挿入するボルト３０を介し着脱自在に取付けることができる。 That is, since the tank partition wall 25 of the embodiment forms a series of rib-shaped mounting pieces 25b on the outer peripheral side of the wide plate surface of the partition wall plate 25a, the segmenter 10 is used while using a thin iron plate aimed at weight reduction. It can be mounted and supported with rigidity, and as shown in FIG. 3B, both ends of the mounting seat 25c having an L-shaped cross section are joined at appropriate positions between the wide plate surface and the mounting piece 25b to form a rigid body structure. To. The mounting seat 25c has a screw hole formed in a flat seat surface facing outward, and is detachably attached to the seat surface via a bolt 30 for inserting the segmenter 10 into the support case 10a on the upper side. be able to.

尚、図示例のセジメンタ１０は在来のものと同様に、上記支持ケース１０ａと、該支持ケース１０ａの下部に挿脱自在に取付けられ、燃料油と水とを分離して貯留し、且つ溜まり水を点検可能とする透明部材からなる貯水部（点検ケース）１０ｂとからなる。
そして、支持ケース１０ａの一方と他方とには、それぞれ燃料タンク８側に連通するタンク側パイプ１０ｃと、エンジンＥ側に連通するエンジン側パイプ１０ｄとを各接続し、両者間に貯水部１０ｂへの燃料油の流入と停止を司る燃料コック１０ｅを備え、また貯水部１０ｂの底部には溜まり水を排出するドレンコック１０ｆを設けている。 The segmenter 10 in the illustrated example is detachably attached to the support case 10a and the lower part of the support case 10a, as in the case of the conventional one, to separate and store fuel oil and water, and to collect the fuel oil and water. It is composed of a water storage unit (inspection case) 10b made of a transparent member that enables inspection of water.
Then, a tank-side pipe 10c communicating with the fuel tank 8 side and an engine-side pipe 10d communicating with the engine E side are connected to one and the other of the support cases 10a, respectively, to the water storage unit 10b between the two. A fuel cock 10e that controls the inflow and stoppage of the fuel oil of the above is provided, and a drain cock 10f that discharges accumulated water is provided at the bottom of the water storage unit 10b.

以上の構成によってタンク隔壁２５に取付けられるセジメンタ１０は、前記給油管２６の後方に隣接した縦向きの並列状態に配置され、且つ支持ケース１０ａが取付座２５ｃを介し隔壁板２５ａから外方に向け離間した位置でボルト止めされる。
これにより隔壁板２５ａから離間して縦向きに配設されるセジメンタ１０は、セジメンタメンテナンス作業としてドレンコック１０ｆを開けて貯水部１０ｂ内の溜まり水を排水するとき、排水を機体フレーム２や周囲を濡らすことなく地上に向けスムーズに放出する水抜き作業を可能にしている。 The sequencer 10 attached to the tank partition wall 25 by the above configuration is arranged in a vertically parallel state adjacent to the rear of the oil supply pipe 26, and the support case 10a is directed outward from the partition plate 25a via the mounting seat 25c. It is bolted at a separated position.
As a result, the segmenter 10 is arranged vertically away from the partition plate 25a. It enables the drainage work to smoothly discharge the water to the ground without getting it wet.

また支持ケース１０ａから取外して行う貯水部１０ｂの分解清掃等も、給油作業高さと略同じ高さ位置において着脱作業を容易且つ速やかに行うことができるため、一連のメンテナンス作業を能率よく行うことができる。
さらに、実施形態のコンバイン１は、従来のものようにセジメンタ１０を機体後部に立設されて他部品が取付けられる外装フレーム等に設けることなく、塵埃や泥土飛散の少ないタンク隔壁２５の外方に配置するため、燃料パイプ類を配索する際の急角度の屈曲や近隣配線部品との接触等の配索リスクを回避できると共に、タンク隔壁２５を取付部材に兼用することにより纏まりのよいセジメンタ配置構造にすることができる。 Further, the disassembly and cleaning of the water storage unit 10b, which is removed from the support case 10a, can be easily and quickly performed at a position substantially equal to the refueling work height, so that a series of maintenance work can be efficiently performed. can.
Further, the combine 1 of the embodiment is provided on the outside of the tank partition wall 25, which is less likely to scatter dust and mud, without providing the sequencer 10 on the exterior frame or the like which is erected at the rear part of the machine body and to which other parts are attached as in the conventional case. Because of the arrangement, it is possible to avoid the risk of arrangement such as bending at a steep angle when arranging fuel pipes and contact with neighboring wiring parts, and the tank partition wall 25 is also used as a mounting member to arrange the segmenter in a well-organized manner. Can be structured.

次に、図２,図４を参照し給油口カバー１１について説明する。この給油口カバー１１は、脱穀機体の側壁に対しワンタッチ着脱機構を介して取付けられており、その装着状態において給油口部８ａの口蓋２６ａとセジメンタ１０とに対向する位置に開口部１１ａを穿設形成している。
即ち、実施形態の開口部１１ａは、給油口部８ａの口蓋２６ａとセジメンタ１０とを共に外方から視認可能な形状となし、且つここから挿入する手によって口蓋２６ａの開閉操作と燃料コック１０ｅの切換操作をすることができる。 Next, the fuel filler port cover 11 will be described with reference to FIGS. 2 and 4. The refueling port cover 11 is attached to the side wall of the threshing machine via a one-touch attachment / detachment mechanism, and an opening 11a is formed at a position facing the palate 26a of the refueling port portion 8a and the segmenter 10 in the mounted state. Is forming.
That is, the opening 11a of the embodiment has a shape in which both the palate 26a and the segmenter 10 of the fuel filler port 8a can be visually recognized from the outside, and the palate 26a can be opened and closed and the fuel cock 10e can be opened and closed by a hand inserted from the palate 26a. Switching operation can be performed.

実施形態の給油口カバー１１は、開口部１１ａに外方から開閉操作可能とする開口部カバー２８を設けており、この場合には開口部カバー２８は透明合成樹脂製の透明板で構成することが望ましく、これにより雨水や塵埃等の侵入を防止すると共に、カバー閉じ状態のまま給油口カバー１１を取外すことなく、外方からセジメンタ１０の水位視認をすることができる。尚、ドレンコック１０ｆの切換操作を開口部１１ａ内に挿入した手によって行う場合には、開口部１１ａの形状や大きさを変更することによって容易に対応することができる。また開口部カバー２８は、前部側を縦軸支点に開閉自在にする蝶番構造によって取付支持することが望ましい。 The fuel filler port cover 11 of the embodiment is provided with an opening cover 28 that can be opened and closed from the outside in the opening 11a. In this case, the opening cover 28 is made of a transparent plate made of transparent synthetic resin. This makes it possible to prevent rainwater, dust, and the like from entering, and to visually recognize the water level of the segmenter 10 from the outside without removing the fuel filler port cover 11 while the cover is closed. When the switching operation of the drain cock 10f is performed by a hand inserted into the opening 11a, it can be easily handled by changing the shape and size of the opening 11a. Further, it is desirable that the opening cover 28 is attached and supported by a hinge structure that allows the front side to be opened and closed with the vertical axis fulcrum.

次に、図５,図６を参照し機体フレーム２の左側に沿って構成される補助ステップ７について説明する。この補助ステップ７は在来のものと同様な構成によって、前記２点鎖線で示す脱穀部４の外側ラインＦに沿う図５で示す収納姿勢と、図６で示すように外側ラインＦから外方に向けて大きく略平行状に突出するステップ姿勢とに切り換え可能にしている。 Next, the auxiliary step 7 configured along the left side of the airframe frame 2 will be described with reference to FIGS. 5 and 6. The auxiliary step 7 has a configuration similar to that of the conventional one, and has a storage posture shown in FIG. 5 along the outer line F of the threshing portion 4 shown by the two-dot chain line and outward from the outer line F as shown in FIG. It is possible to switch to a step posture that protrudes in a large and substantially parallel manner toward.

尚、図中に２点鎖線で示す外側ラインＦは、前記脱穀部４の左側の最外方である本体側カバー９と給油口カバー１１の平面視における輪郭線である。
そして、上記補助ステップ７は図1,図２,図６に示すステップ姿勢では、前側を前処理部３の未刈り地側の未刈り茎稈の機体側への倒れ込みを防止する規制作用姿勢にあるナローガイド３２の後部に近接する外方位置に突出させることができる。 The outer line F shown by the alternate long and short dash line in the figure is a contour line in a plan view of the main body side cover 9 and the fuel filler port cover 11, which are the outermost on the left side of the threshing portion 4.
Then, in the step postures shown in FIGS. 1, 2 and 6, the auxiliary step 7 is set to a restrictive posture in which the front side is prevented from falling toward the machine body side of the uncut stalk culm on the uncut ground side of the pretreatment unit 3. It can be projected to an outward position close to the rear part of a narrow guide 32.

即ち、図示例の補助ステップ７は、機体フレーム２の左外側に前後一対のリンク節７ａ，７ｂを縦向きの取付軸を介して枢設すると共に、該リンク節７ａ，７ｂの先端に縦向きの取付軸を介し前後方向に長いステップ部材７ｃを取付けた平行リンク構造にしている。これにより作業者は、補助ステップ７を収納姿勢からステップ姿勢に切換えステップ部材７ｃに乗り上がり前後方向に移動しながら、脱穀部４や排藁処理部４ａ等各所のメンテナンス作業を行うことができる。 That is, in the auxiliary step 7 of the illustrated example, a pair of front and rear link sections 7a and 7b are pivotally installed on the left outer side of the airframe frame 2 via a vertically oriented mounting shaft, and are vertically oriented at the tips of the link sections 7a and 7b. It has a parallel link structure in which a long step member 7c is attached in the front-rear direction via the attachment shaft of the above. As a result, the operator can switch the auxiliary step 7 from the storage posture to the step posture, ride on the step member 7c, move in the front-rear direction, and perform maintenance work at various places such as the threshing section 4 and the straw disposal section 4a.

また給油作業を行うとき作業者は、補助ステップ７をステップ姿勢に切換えた状態で、給油口部８ａの近傍でステップ部材７ｃ又はリンク節７ｂ側に、補給油タンク３１を載置し給油仮置き姿勢にすることができ、載置した補給油タンク３１から給油口部８ａに対する給油作業を行い易くすることができる。
実施形態の補助ステップ７は、後側のリンク節７ｂの基部側に前記給油口部８ａの下方に臨みセジメンタ１０の下部を覆う平板状の泥除け部材３３を設置している。 Further, when performing the refueling work, the operator places the refueling tank 31 on the step member 7c or the link section 7b side in the vicinity of the refueling port 8a with the auxiliary step 7 switched to the step posture, and temporarily places the refueling tank 31. The posture can be set, and the refueling work from the mounted refueling tank 31 to the refueling port 8a can be facilitated.
In the auxiliary step 7 of the embodiment, a flat plate-shaped mudguard member 33 is installed on the base side of the link section 7b on the rear side so as to face below the fuel filler port 8a and cover the lower part of the segmenter 10.

この泥除け部材３３は、補助ステップ７の収納姿勢において上記セジメンタ１０の下方の全体を覆うことができ、湿田圃場を走行するときクローラ走行装置によって跳ね上げられる泥土を下面で受けて、泥土がセジメンタ１０側に付着することを防止する。
そして、補助ステップ７をステップ姿勢に切換えたとき、セジメンタ１０の下方から外方に退避する泥除け部材３３は、補給油タンク３１を仮置きする広幅な載置台として使用することができ、またドレンコック１０ｆを操作して排水される溜まり水の水抜き作業を支障なく行うことようにしている。 The mudguard member 33 can cover the entire lower part of the segmenter 10 in the storage posture of the auxiliary step 7, and receives the mud that is flipped up by the crawler traveling device when traveling in a wet field on the lower surface, and the mud is received by the segmenter 10. Prevents sticking to the side.
Then, when the auxiliary step 7 is switched to the step posture, the mudguard member 33 that retracts from below the sequencer 10 to the outside can be used as a wide mounting table on which the replenishment oil tank 31 is temporarily placed, and the drain cock. The operation of 10f is performed so that the drainage work of the accumulated water to be drained can be performed without any trouble.

次に、上記のように構成されるコンバイン１による給油作業について説明する。先ず、給油作業を行うとき作業者は、機体の左側において補助ステップ７をステップ姿勢に切換えた状態で給油口部８ａの正面側に立ち、補給油タンク３１を補助ステップ７の近傍適所に仮置き載置し、且つ開口部カバー２８を開けると共に口蓋２６ａを外して給油筒２６の給油口を開口する。
次いで、例えば右手で補給油タンク３１に連なる図示しない補給管を給油管２６内に臨ませた給油姿勢となして給油を開始する。 Next, the refueling work by the combine 1 configured as described above will be described. First, when performing the refueling work, the operator stands on the front side of the refueling port 8a with the auxiliary step 7 switched to the step posture on the left side of the machine, and temporarily places the refueling tank 31 in a suitable place near the auxiliary step 7. It is placed and the opening cover 28 is opened, and the palate 26a is removed to open the refueling port of the refueling cylinder 26.
Next, for example, refueling is started with a refueling pipe (not shown) connected to the refueling tank 31 with the right hand in a refueling posture facing the inside of the refueling pipe 26.

そして、作業者は給油量を確認して補給管を抜き去り、口蓋２６ａと開口部カバー２８を閉じ、また補給油タンク３１を降ろし去ることにより一連の給油作業を完了する。
このような給油作業において作業者は、機体フレーム２の給油作業中に、並列状に近接配置されている給油口部８ａとセジメンタ１０とが同時的に視界内に入るため、視線や給油作業姿勢を大きく変更することなく開口部１１ａから、セジメンタ１０の貯水部１０ｂを目視できて溜まり水の水位量を確実に視認することができる。 Then, the operator confirms the amount of refueling, pulls out the refueling pipe, closes the palate 26a and the opening cover 28, and lowers the refueling tank 31 to complete a series of refueling operations.
In such refueling work, during the refueling work of the machine frame 2, the refueling port portions 8a and the sedimentor 10 which are arranged in parallel in close proximity to each other are simultaneously in the field of view, so that the operator can see the line of sight and the refueling work posture. The water storage portion 10b of the segmenter 10 can be visually observed from the opening 11a without significantly changing the amount of the accumulated water, and the water level amount of the accumulated water can be reliably visually recognized.

従って、作業者は、セジメンタ１０の水溜まり点検の要否の有無に関わらず、また失念していたとしても、給油管２６の給油口を目視しながら行う給油や、口蓋２６ａの開閉動作等を行う作業時間中に、セジメンタ１０は目につきやすく敢えて探すことなく視界に入るため、貯水部１０ｂ内の溜まり水の状況を把握することができるので、溜まり水の点検を失念することなくタイムリーに排出し、エンジンブローを防止したスムーズな運転をすることができる。 Therefore, the operator performs refueling while visually observing the refueling port of the refueling pipe 26, opening and closing of the palate 26a, etc., regardless of whether or not the water pool of the sequencer 10 needs to be inspected, and even if he / she forgets. During the working hours, the Sedimentor 10 is easy to see and can be seen without having to look for it, so it is possible to grasp the status of the accumulated water in the water storage unit 10b, so that the accumulated water can be discharged in a timely manner without forgetting to check it. However, smooth operation can be performed while preventing engine blow.

さらに、作業者が給油作業中にセジメンタ１０の点検を意識的行う場合にも、従来のもののように大きく視線をずらして給油作業姿勢を崩すことなく溜まり水の点検を行うことができるので、給油口部８ａに対する給油作業並びにセジメンタ１０の溜まり水の確認等を容易にできると共に、給油作業時と略同高さ位置において溜まり水の排水作業を楽な姿勢で速やかに行うことができる。 Further, even when the operator consciously inspects the Sedimentor 10 during the refueling work, the accumulated water can be inspected without disturbing the refueling work posture by greatly shifting the line of sight as in the conventional one, so that the refueling can be performed. The refueling work for the mouth portion 8a and the confirmation of the accumulated water of the segmenter 10 can be easily performed, and the accumulated water can be quickly drained at a position substantially the same height as the refueling work in a comfortable posture.

また開口部１１ａと開口部カバー２８とを有する単一な給油口カバー１１は、機体フレーム２の給油作業側に着脱自在に設けて給油口部８ａとセジメンタ１０とを開閉自在に覆うと共に、ワンタッチ状に簡単に取外すことができるようにしているため、給油口カバー１１を取外した場合に、セジメンタ配置構造部分の全体を簡単に露出開放できるので、給油作業はもとよりドレンコック１０ｆの排水操作やセジメンタ１０の分解清掃等も行い易くし、一連のメンテナンス作業を能率よくすることができる。 Further, the single refueling port cover 11 having the opening 11a and the opening cover 28 is detachably provided on the refueling work side of the machine frame 2 to cover the refueling port 8a and the segmenter 10 so as to be openable and closable, and one-touch. Since it can be easily removed in a shape, when the fuel filler port cover 11 is removed, the entire segmenter arrangement structure can be easily exposed, so that not only the lubrication work but also the drainage operation of the drain cock 10f and the segmenter can be performed. The disassembly and cleaning of 10 can be easily performed, and a series of maintenance work can be efficiently performed.

そして、図２,図４に示すように、給油作業側で給油口部８ａの口蓋２６ａとセジメンタ１０とを略同じ高さに並べて配置した状態で、開口部１１ａを有する給油口カバー１１で覆うと共に、該開口部１１ａに透明合成樹脂製の開口部カバー２８を設けたセジメンタ配置構造は、機体外方から作業者が透明開口部カバー２８を見たとき、内部のセジメンタ１０を意識的に透視して溜まり水の点検動作を喚起するため、こまめな排水作業を促してエンジンブローを生じないスムーズな運転を可能にする等の利点もある。 Then, as shown in FIGS. 2 and 4, the lid 26a of the refueling port 8a and the segmenter 10 are arranged side by side at substantially the same height on the refueling work side, and covered with the refueling port cover 11 having the opening 11a. At the same time, the segmenter arrangement structure in which the opening cover 28 made of transparent synthetic resin is provided in the opening 11a consciously sees through the internal segmenter 10 when the operator sees the transparent opening cover 28 from the outside of the machine body. This has the advantage of encouraging diligent drainage work and enabling smooth operation without causing engine blow, because it encourages the inspection operation of accumulated water.

尚、図示例の給油口カバー１１は、給油口部８ａの口蓋２６ａとセジメンタ１０とを視認可能な大きさの１つの開口部１１ａを形成すると共に、該開口部１１ａを開閉する開口部カバー２８を透明合成樹脂製として構成したが、これに限ることなく例えば、給油口カバー１１に口蓋２６ａとセジメンタ１０とを個別に視認可能な２つの開口部１１ａをそれぞれ穿設形成した状態で、給油口カバー１１に該２つの開口部１１ａを覆う半透明又は非透明部材からなる給油口カバー１１を開閉自在に設ける構成にしてもよいものである。 The fuel filler port cover 11 of the illustrated example forms one opening 11a having a size so that the palate 26a of the fuel filler port 8a and the segmenter 10 can be visually recognized, and the opening cover 28 that opens and closes the opening 11a. Is made of transparent synthetic resin, but the fuel filler port is not limited to this. A fuel filler port cover 11 made of a translucent or non-transparent member covering the two openings 11a may be provided on the cover 11 so as to be openable and closable.
