Description

本発明は、操縦部の後方の機体左右両側にてフロアステップよりも高位置に形成されたリヤステップを有する乗用田植機に関する。 The present invention relates to a riding rice transplanters having rear step formed in a position higher than the floor step at the rear of the fuselage left and right sides of the steering unit.

従来の乗用田植機等において、運転席の座席シートの左右両側には、オペレータが乗車したまま機体後部に行くための左右幅広な作業用のステップが配設されていて、このステップ下方には、燃料タンクが配置されていた。そして、前記ステップのうち、燃料タンクの給油口に対応する部分を、閉蓋姿勢と開蓋姿勢とに開閉自在な蓋に構成していた。すなわち、燃料タンクを略々水平なステップの下方に設け、かつ給油口をステップ部分で構成されるフラットな蓋で覆ったものが公知である（例えば、特許文献１参照）。   In conventional passenger rice transplanters and the like, on both the left and right sides of the seat seat of the driver's seat, there are steps for wide left and right work for the operator to go to the rear of the aircraft while riding, below this step, A fuel tank was in place. In the step, the portion corresponding to the fuel filler opening of the fuel tank is configured as a lid that can be freely opened and closed between a closed posture and an open posture. That is, a fuel tank is provided under a substantially horizontal step, and a fuel filler port is covered with a flat lid formed of a step portion (for example, see Patent Document 1).

特開２００２−９５３１８号公報（第５頁、図２、図１４）JP-A-2002-95318 (5th page, FIG. 2, FIG. 14)

しかし、従来の技術のように、燃料タンクの給油口を、運転席の足元に形成された略々水平な足載せ用のステップの下方に設けたものでは、該ステップ部に付着した泥土が給油口に入り込んだり、ステップ面に降った雨水や泥水が給油口から燃料タンク内に侵入し、エンジン性能が低下するおそれがあった。また、圃場での作業中に燃料タンクの給油口から燃料を補給する際、通常、燃料入りのポリタンクを用いるが、従来の給油口の配置では、ポリタンクをどこに置いて補給作業をすれば良いか、その置場に困っていた。   However, in the case where the fuel tank filler opening is provided below the substantially horizontal footrest step formed at the foot of the driver's seat as in the prior art, mud adhering to the step portion is oiled. There was a risk that rainwater or muddy water that entered the mouth or fell on the step surface entered the fuel tank from the fuel filler port, resulting in a decrease in engine performance. Also, when fuel is replenished from the fuel tank refueling port during work in the field, a fuel-filled polytank is usually used, but with the conventional refueling port arrangement, where should the polytank be placed for replenishment work? , I was in trouble with the place.

本発明は、斯かる課題を解決するためになされたもので、その目的とするところは、給油部付近に泥土が付着したり燃料タンク内に泥水が侵入するのを防止し、かつ作業中の燃料補給を容易に行うことのできる乗用田植機を提供することにある。 The present invention has been made to solve such a problem.

なお、上述した括弧内の符号は図面を参照するために示すものであって、本発明を何ら限定するものではない。   In addition, the code | symbol in the parenthesis mentioned above is shown in order to refer drawings, Comprising: This invention is not limited at all.

請求項１に係る発明によれば、前輪及び後輪の機体前後方向の中間部で、かつフロアステップの下方に燃料タンクを設け、該燃料タンクの給油部を、フロアステップとリヤステップとをつなぐ立上り連結部に配設したので、給油部付近に泥等が付着するのを防止することができる。また、給油部を立上り連結部の傾斜面に設け、泥水は流れ落ちるので、該泥水が燃料タンク内に侵入するのを防止することができる。更に、例えば、機体側方の高位置（リヤステップ）にポリタンクを置いて下方の給油部に給油するので、圃場作業中の給油を容易に行うことができる。   According to the first aspect of the present invention, the fuel tank is provided in the middle of the front and rear wheels in the front-rear direction of the fuselage and below the floor step, and the refueling portion of the fuel tank is connected to the floor step and the rear step. Since it is disposed at the rising connection portion, mud or the like can be prevented from adhering to the vicinity of the oil supply portion. Further, since the oil supply portion is provided on the inclined surface of the rising connection portion and the muddy water flows down, the muddy water can be prevented from entering the fuel tank. Furthermore, for example, since a plastic tank is placed at a high position (rear step) on the side of the machine body and the oil is supplied to the lower oil supply section, it is possible to easily supply oil during field work.

請求項２に係る発明によれば、開閉板を、立上り連結部の傾斜面に沿う閉姿勢からフロアステップ側への回動操作により開姿勢となるようにしたので、例えばリヤステップ上に燃料補給用のポリタンクを置き、このポリタンクから給油管を給油部に延ばして容易に給油を行うことができる。また、この際、傾斜面上の泥等が給油部から燃料タンクに入ることはない。   According to the second aspect of the present invention, the opening / closing plate is brought into the open posture by the turning operation from the closed posture along the inclined surface of the rising connecting portion to the floor step side. Therefore, it is possible to supply oil easily by extending an oil supply pipe from the plastic tank to the oil supply section. At this time, mud or the like on the inclined surface does not enter the fuel tank from the oil supply section.

請求項３に係る発明によれば、燃料タンクのタンク本体と給油部とを接続する燃料導入部を、立上り連結部の傾斜面に沿わせて偏平状に形成したので、下方にタンク本体の形状を大きくとってタンク容量を確保することができる。また、偏平状に形成した燃料導入部が、後輪に付着した泥を落す役目を担うことになり、後輪に長時間に亘って泥が付着するのを防止することができる。   According to the invention of claim 3, since the fuel introduction part for connecting the tank body and the fuel supply part of the fuel tank is formed flat along the inclined surface of the rising connection part, the shape of the tank body is formed below. The tank capacity can be secured by taking large. Further, the fuel introduction portion formed in a flat shape plays a role of dropping mud adhering to the rear wheel, and mud can be prevented from adhering to the rear wheel for a long time.

A link holder 26 is pivotally attached to the rear end portion of the elevating link mechanism 23, and the planting portion 24 has left and right sides of the traveling machine body 14 by a rolling shaft (not shown) protruding rearward from the link holder 26. It is supported so that it can follow the rice field regardless of the slope. The planting unit 24 includes a seedling mounting table 28 that is inclined to the front and rear so that a mat seedling is placed and the rear is lowered, a rectangular tube-shaped planting unit frame 32 that extends in the left-right direction of the machine body, and the planting unit 24. A plurality of planting cases 30 for planting extending rearward from the transmission case 31 fixed to the attachment frame 32, and a rotary case 33 having a planting rod 29 provided at the rear end of the planting case 30. And. Power is supplied to the transmission case 31 from the planting PTO shaft 35. Below the planting case 30, a float 34 having a sliding function is attached.

なお、植付部２４の前方でかつ後輪１２の後方との間の空間には、複数のかご型ロータ３６が所定間隔で取付けられていて、このかご型ロータ３６により、圃場の植付面を代掻きして、平滑に代掻きされた圃場に植付杆２９によって苗が植付けられる。このかご型ロータ３６は、各フロート３４の前方において機体左右方向に横設されたロータリ軸３７に支持されている。   A plurality of squirrel-cage rotors 36 are attached at a predetermined interval in a space between the front of the planting unit 24 and the rear of the rear wheel 12. The seedlings are planted by the planting rod 29 in the field that has been scraped smoothly. The squirrel-cage rotor 36 is supported by a rotary shaft 37 that is horizontally provided in the left-right direction of the body in front of each float 34.

本実施形態において、前輪１１と後輪１２の機体前後方向の中間部で、かつフロアステップ２１の下方に燃料タンク５０を設け、該燃料タンク５０の給油部５１を、フロアステップ２１とリヤステップ２２とをつなぐ立上り連結部５２に配設している。すなわち、図３に示すように、ボンネット１６を挟んでその機体左右両側に補助苗載せ台７０が取付けられていて、また、フロアステップ２１とリヤステップ２２とは、該フロアステップ２１の後端部から後方に向けて高くなるように傾斜する立上り連結部５２によって連結されている。   In the present embodiment, a fuel tank 50 is provided at an intermediate portion of the front wheel 11 and the rear wheel 12 in the longitudinal direction of the vehicle body and below the floor step 21, and the fuel supply portion 51 of the fuel tank 50 is connected to the floor step 21 and the rear step 22. Are arranged in the rising connecting portion 52 connecting the two. That is, as shown in FIG. 3, auxiliary seedling rests 70 are attached to the left and right sides of the machine body with the bonnet 16 interposed therebetween, and the floor step 21 and the rear step 22 are arranged at the rear end portion of the floor step 21. Are connected by a rising connecting portion 52 that is inclined so as to become higher toward the rear.

そして、燃料タンク５０の給油部５１は、給油口（図示せず）と該給油口を塞ぐキャップ５１ａを有し、この給油部５１が立上り連結部５２の傾斜面の上下方向の中途部に配設されている。これにより、燃料タンク５０の給油部５１の付近に泥等がかからなくなると共に、立上り連結部５２の傾斜面に設けたので、泥水は流れ落ち、燃料タンク５０内に侵入するのが防止される。   The fuel supply portion 51 of the fuel tank 50 has a fuel supply port (not shown) and a cap 51a that closes the fuel supply port. The fuel supply portion 51 is arranged in the middle of the inclined surface of the rising connection portion 52 in the vertical direction. It is installed. Accordingly, mud or the like is not applied near the fuel supply portion 51 of the fuel tank 50, and the muddy water is prevented from flowing into the fuel tank 50 because it is provided on the inclined surface of the rising connection portion 52.

また、燃料タンク５０は、そのタンク本体と給油部５１とを接続する燃料導入部５０ａが、前記立上り連結部５２の傾斜面に沿って偏平状に形成されている。更に、この燃料導入部５０ａの上端に位置する給油部５１（給油口及びキャップ５１ａ）が、傾斜面の中途部に位置している。このように、燃料導入部５０ａを立上り連結部５２の傾斜面に沿わせて偏平状に形成したので、下方にタンク形状を大きくとれて、タンク容量を大きく確保することができる。また、燃料タンク５０を合成樹脂による成形手段により形成した場合、燃料導入部５０ａをパイプ状とすると成形が困難であるが、本実施形態のように偏平状としたことで成形が容易となる。更に、燃料導入部５０ａを立上り連結部５２の傾斜面に沿って偏平状としたので、この偏平部分で後輪１２の泥落しとなる利点もある。   Further, the fuel tank 50 has a fuel introduction portion 50 a that connects the tank body and the fuel supply portion 51 formed in a flat shape along the inclined surface of the rising connection portion 52. Further, a fuel filler 51 (fuel filler and cap 51a) located at the upper end of the fuel introduction part 50a is located in the middle of the inclined surface. Thus, since the fuel introduction part 50a is formed in a flat shape along the inclined surface of the rising connection part 52, the tank shape can be largely taken downward to ensure a large tank capacity. Further, when the fuel tank 50 is formed by a synthetic resin molding means, it is difficult to mold the fuel introduction portion 50a in the shape of a pipe, but molding is facilitated by adopting a flat shape as in this embodiment. Further, since the fuel introduction part 50a is flattened along the inclined surface of the rising connecting part 52, there is also an advantage that mud dropping of the rear wheel 12 occurs at this flat part.

更に、図４に示すように、給油部５１は開閉板５４によって開閉自在とされていて、該開閉板５４は、その下方部の枢支部５５を中心として上方が開くように回動自在に構成されている。すなわち、開閉板５４は、立上り連結部５２の傾斜面に沿った閉姿勢から、枢支部５５を中心としてフロアステップ２１側に回動操作することで開姿勢となるように構成されている。このため、例えば燃料入りのポリタンク５６をリヤステップ２２の上に置いた場合、該ポリタンク５６から燃料タンク５０の給油口に向けて給油管５７を延ばせば、乗車したまま燃料の補給作業を容易に行うことができる。   Further, as shown in FIG. 4, the oil supply portion 51 is openable and closable by an opening / closing plate 54, and the opening / closing plate 54 is configured to be rotatable so that the upper portion is opened around a pivot portion 55 at the lower portion thereof. Has been. That is, the opening / closing plate 54 is configured to be in an open posture by rotating from the closed posture along the inclined surface of the rising connection portion 52 to the floor step 21 side around the pivotal support portion 55. For this reason, for example, when the fuel-filled poly tank 56 is placed on the rear step 22, if the fuel pipe 57 is extended from the poly tank 56 toward the fuel port of the fuel tank 50, the fuel replenishment work can be facilitated while riding. It can be carried out.

次に、図５を参照しながら、本実施形態の作用を簡単に説明する。   Next, the operation of the present embodiment will be briefly described with reference to FIG.

例えば、圃場での作業中において、燃料タンク５０内の燃料が不足したり燃料切れになった場合、補給用燃料が入ったポリタンク５６をリヤステップ２２の上面に置き、フロアステップ２１とリヤステップ２２とをつなぐ立上り連結部５２に配置した開閉板５４を、下方部の枢支部５５を中心として図の矢印方向に開放する。次いで、給油部５１のキャップ５１ａを外して、ポリタンク５６から給油口に向けて給油管５７を延ばし、ポンプ（図示せず）にてポリタンク５６内の燃料を補給すれば良い。このとき、開閉板５４は上から下に開閉するので、立上り連結部５２に付着した泥等が給油部５１に入り込むことはないし、ステップに乗ったまま圃場作業中の燃料の補給作業を容易に行うことができる。   For example, when the fuel in the fuel tank 50 runs out or runs out of fuel during work on the field, the polytank 56 containing the supplementary fuel is placed on the upper surface of the rear step 22, and the floor step 21 and the rear step 22. The opening / closing plate 54 disposed in the rising connecting portion 52 is connected to the lower support portion 55 in the direction of the arrow in the figure. Next, the cap 51a of the oil supply section 51 is removed, the oil supply pipe 57 is extended from the poly tank 56 toward the oil supply port, and the fuel in the poly tank 56 may be replenished with a pump (not shown). At this time, the opening / closing plate 54 opens and closes from the top to the bottom, so that mud or the like adhering to the rising connection portion 52 does not enter the fuel supply portion 51, and it is easy to replenish fuel during field work while riding on the steps. It can be carried out.
