Description

本発明は、機体上にエンジンを搭載した移動農機に係り、詳しくは、移動農機における燃料タンクの保護カバーに関する。   The present invention relates to a mobile agricultural machine having an engine mounted on a machine body, and more particularly, to a protective cover for a fuel tank in the mobile agricultural machine.

従来より、各種、燃料タンクの保護カバーを備えた移動農機がある。（例えば、特許文献１参照。）
実開平５−８９０５７号公報（図１、図４）。 Conventionally, there are various types of mobile agricultural machines equipped with protective covers for fuel tanks. (For example, refer to Patent Document 1.)
Japanese Utility Model Laid-Open No. 5-89057 (FIGS. 1 and 4).

前述のような移動農機の燃料タンクは、軽量化及び低コスト化の面から樹脂で一体成型されて構成されているものが多い。
この場合、特許文献１に開示されているように、燃料ゲージ取付用の取付座と給油口とを並べて備えた給油部を射出成型により一体成型し、燃料タンク本体とは別の部材として用意しておき、タンク本体の成型時又は成型後に燃料ゲージ取付用の取付座と給油口とを燃料タンク本体に取り付けるものである。 In many cases, the fuel tank of the mobile agricultural machine as described above is integrally formed of resin from the viewpoint of weight reduction and cost reduction.
In this case, as disclosed in Patent Document 1, a fueling portion provided with a fuel gauge mounting seat and a fuel filler opening is integrally formed by injection molding, and prepared as a separate member from the fuel tank body. The fuel gauge mounting seat and the fuel filler port are attached to the fuel tank main body when or after the tank main body is molded.

しかし、前述の燃料タンクにおいては、給油口とは別に燃料ゲージを取り付けるための取付座を別途、射出成型により一体成型しているため製造コストが高くなるという問題がある。   However, the above-described fuel tank has a problem that the manufacturing cost increases because a mounting seat for mounting the fuel gauge is separately formed by injection molding separately from the fuel filler port.

本発明の目的は、低コストで燃料タンクの給油量を容易に把握することにある。   An object of the present invention is to easily grasp the amount of fuel supplied to a fuel tank at a low cost.

本発明は、機体にエンジンと透過性を有する燃料タンクを配設してなる移動農機において、上記燃料タンクの上方に、該燃料タンクを覆って保護する保護カバーを設け、該保護カバーの上面には、上記燃料タンクの注入部に対応する位置に開口部を設けると共に、該開口部近傍に給油量確認窓を設けた移動農機を提供せんとするものである。   The present invention provides a mobile agricultural machine in which a fuel tank having permeability to an engine is disposed in a machine body, and a protective cover that covers and protects the fuel tank is provided above the fuel tank, and is provided on an upper surface of the protective cover. Is intended to provide a mobile agricultural machine having an opening at a position corresponding to the injection portion of the fuel tank and a fuel supply amount confirmation window in the vicinity of the opening.

また、保護カバーの給油量確認窓を、燃料タンクの注入部に対応する位置の開口部に連続して形成したことを特徴とする移動農機を提供せんとするものである。   Further, the present invention is to provide a mobile agricultural machine characterized in that the oil amount confirmation window of the protective cover is continuously formed in the opening portion at a position corresponding to the injection portion of the fuel tank.

そして、燃料タンクの上面を前低後高に構成すると共に、給油量確認窓を前後方向に長い開口部で形成したことを特徴とする移動農機を提供せんとするものである。   Then, the upper surface of the fuel tank is configured to be front-rear and rear-high, and a fuel supply confirmation window is formed with a long opening in the front-rear direction.

さらに、保護カバーの側面に燃料タンクの燃料の残量を確認するための残量確認窓を設けたことを特徴とする移動農機を提供せんとするものである。   Furthermore, the present invention is intended to provide a mobile agricultural machine characterized in that a remaining amount confirmation window for confirming the remaining amount of fuel in the fuel tank is provided on the side surface of the protective cover.

以上の構成に基づき、機体にエンジンと透過性を有する燃料タンクを配設してなる移動農機において、上記燃料タンクの上方に、該燃料タンクを覆って保護する保護カバーを設け、該保護カバーの上面には、上記燃料タンクの注入部に対応する位置に開口部を設けると共に、該開口部近傍に給油量確認窓を設けたことで、作業者が誤って燃料タンクの容量を超えて燃料を注入しようとするのを防止することで、燃料が燃料タンクから溢れ出るのを未然に防止することができる。つまり、給油量確認窓は、燃料が燃料タンク内で満杯近くになるのを防止するために設けられている。   Based on the above configuration, in the mobile agricultural machine in which the fuel tank having permeability to the engine is disposed on the machine body, a protective cover that covers and protects the fuel tank is provided above the fuel tank. On the upper surface, an opening is provided at a position corresponding to the injection portion of the fuel tank, and an oil supply amount confirmation window is provided in the vicinity of the opening so that an operator can accidentally exceed the capacity of the fuel tank and supply fuel. By preventing the injection, the fuel can be prevented from overflowing from the fuel tank. That is, the fuel supply amount confirmation window is provided to prevent the fuel from becoming nearly full in the fuel tank.

また、保護カバーの給油量確認窓を、燃料タンクの注入部に対応する位置の開口部に連続して形成したことで、保護カバーに給油量確認窓を形成するのに工数を多くかけなくても給油量確認窓を保護カバーに形成することが可能である。   In addition, the oil amount confirmation window for the protective cover is formed continuously in the opening at the position corresponding to the injection portion of the fuel tank, so that it does not take much time to form the oil amount confirmation window for the protective cover. Also, it is possible to form the oil supply amount confirmation window on the protective cover.

そして、燃料タンクの上面を前低後高に構成すると共に、給油量確認窓を前後方向に長い開口部で形成したことで、燃料タンクに燃料を注入する際に、燃料タンクの低い方から高い方に徐々に入るのが給油量確認窓から作業者が視認することが可能となる。   In addition, the upper surface of the fuel tank is configured to be front-rear and rear-high, and the fuel supply amount confirmation window is formed with an opening that is long in the front-rear direction, so that when fuel is injected into the fuel tank, it is higher from the lower fuel tank. It is possible for the worker to visually recognize the oil gradually entering the direction from the oil supply amount confirmation window.

さらに、保護カバーの側面に燃料タンクの燃料の残量を確認するための残量確認窓を設けたことで、保護カバーを取り外さなくても燃料の残量の確認を残量確認窓から作業者が視認することができる。   In addition, by providing a remaining amount confirmation window on the side of the protective cover to confirm the remaining amount of fuel in the fuel tank, the operator can check the remaining amount of fuel from the remaining amount confirmation window without removing the protective cover. Can be visually recognized.

The connecting frame X rotates the lifting wheel support arm 41a that pivotally supports the lifting wheel 41. Dynamic adjustment is possible (height adjustment is possible).

これにより、昇降車輪４１を図１の実線の状態から最下位にセットすると、走行車輪１６、１６との間でロータリ耕耘部２を地面から離間する方向に浮上支持することができ、スムーズな路上走行を行うことができる。また、昇降車輪４１を上方に順次位置決め固定すると、走行車輪１６、１６の接地位置に基づきロータリ耕耘部２を段階的に下げることができ、耕耘深さを順次深くした耕耘作業を行うことができる。   Thereby, when the elevating wheel 41 is set to the lowest position from the state of the solid line in FIG. 1, the rotary tiller 2 can be levitated and supported in a direction away from the ground between the traveling wheels 16 and 16, and on a smooth road It is possible to run. Further, if the lifting and lowering wheels 41 are sequentially positioned and fixed upward, the rotary tiller 2 can be lowered stepwise based on the ground contact position of the traveling wheels 16 and 16, and the tilling work can be performed with the tilling depth gradually increased. .

上記ロータリ耕耘部２は、図１に示すように、耕耘爪１８を放射状にそれぞれ取着した耕耘軸１７を機体中央に配設される伝動ケース１４の左右側方に延出し、前記操作レバー４の切換操作により切り換えられたエンジン１１の回転動力を伝動ケース１４から耕耘軸１７に伝達して耕耘爪１８を正回転駆動している。   As shown in FIG. 1, the rotary tiller 2 extends a tiller shaft 17 with the tillers 18 attached radially to the left and right sides of a transmission case 14 disposed in the center of the machine body, and the operation lever 4. The rotational power of the engine 11 switched by the switching operation is transmitted from the transmission case 14 to the tilling shaft 17 to drive the tilling claw 18 in the normal direction.

以上の構成のもので、作業者がエンジンを始動して機体１を走行させて農作業を行う場合、前記昇降車輪４１を図１で記載の如く、前記ロータリ耕耘部２が最も低くなる位置にセットすると共に、操作レバー４の位置をレバーガイドパネル５の移動位置に合わせて、ハンドル３２先端に装着されたクラッチレバー３３ａを握って図１の実線位置とすれば、図示しない動力伝動装置が駆動されて、機体１が前進するものであり、逆に後進したい時には、前記操作レバー４の位置をレバーガイドパネル５の後進位置にセットし、前記と同様にクラッチレバー３３ａを握れば、機体１は後進するものである。   With the above configuration, when the operator starts the engine and runs the airframe 1 to perform farm work, the lifting wheel 41 is set at a position where the rotary tiller 2 is lowest as shown in FIG. At the same time, if the position of the operating lever 4 is adjusted to the moving position of the lever guide panel 5 and the clutch lever 33a mounted at the tip of the handle 32 is gripped to the solid line position in FIG. 1, a power transmission device (not shown) is driven. Thus, when the machine body 1 is moving forward, and when it is desired to move backward, the position of the operation lever 4 is set to the reverse drive position of the lever guide panel 5, and the clutch lever 33a is gripped in the same manner as described above, the machine body 1 moves backward. To do.
