Description

本発明は、主として野外の建設・土木現場等で使用されるエンジン作業機に関する。   The present invention relates to an engine working machine used mainly in outdoor construction / civil engineering sites.

エンジン作業機は、エンジンと、該エンジンにより駆動される発電機、ウエルダー、コンプレッサー、油圧ユニット等の動力供給源とを床台上に搭載し、エンジンより発する騒音を低減するために、防音構造のケーシングにてエンジン及び動力供給源を覆っている。前記エンジンの燃料タンクは、前記床台上に配置されているものが一般的であるが、長時間燃料無補給で運転することが要求される現場で使用するために、前記エンジン下方の床台内に大容量の燃料タンクを配置したものがある(例えば、特許文献1参照。)。
特開2000−265848公報 第1〜6頁 図3,4,7,8
The engine working machine is equipped with an engine and a power supply source such as a generator, a welder, a compressor, and a hydraulic unit driven by the engine on the floor, and has a soundproof structure in order to reduce noise generated from the engine. The casing covers the engine and power supply. The fuel tank of the engine is generally arranged on the floor, but for use in a field where it is required to operate without refueling for a long time, the floor under the engine is used. Some have a large-capacity fuel tank disposed therein (see, for example, Patent Document 1).
JP, 2000-265848, pp. 1-6 FIGS.

このエンジン作業機は、野外で使用されることが多いことから、燃料タンク内に土砂等の粉塵が付着混入することがあるため、定期的に燃料タンクの洗浄を行う必要がある。通常は、燃料タンクの給油口から洗浄ノズルを挿入して内部の洗浄作業を行うが、このような洗浄方法では、タンクの底部に溜まった土砂等の不純物を完全に取り去ることが困難であった。さらに、大容量の燃料タンクは、通常内部に仕切り板があるため、1カ所の開口では底部全体を洗浄しにくい。   Since this engine work machine is often used outdoors, dust such as earth and sand may be adhering to the fuel tank, so it is necessary to periodically clean the fuel tank. Normally, the cleaning nozzle is inserted from the fuel tank filler port to perform the internal cleaning work. However, with such a cleaning method, it is difficult to completely remove impurities such as earth and sand accumulated at the bottom of the tank. . Furthermore, since a large-capacity fuel tank usually has a partition plate inside, it is difficult to clean the entire bottom portion with a single opening.

そこで本発明は、洗浄作業時に燃料タンクの内部を目視可能として、タンクの底部に溜まった土砂等の不純物を完全に取り去ることができるエンジン作業機を提供することを目的としている。   SUMMARY OF THE INVENTION An object of the present invention is to provide an engine working machine that can visually check the inside of a fuel tank during a cleaning operation and can completely remove impurities such as earth and sand accumulated at the bottom of the tank.

上記した目的を達成するため、本発明は、床台上にエンジンと、該エンジンにより駆動される動力供給源とを搭載し、前記床台内にエンジンの燃料タンクを配置したエンジン作業機において、前記燃料タンクの天板に内部を目視可能な開口部を形成するとともに、該開口部に蓋を被着することを特徴としている。また、前記燃料タンクは、前記床台に一体に形成されている場合と、、前記床台とは別体に形成され、前記天板は、前記床台の床板と兼用であって、前記燃料タンクの側板に着脱可能に取り付けられる場合とがある。   In order to achieve the above-described object, the present invention provides an engine working machine in which an engine and a power supply source driven by the engine are mounted on a floor, and a fuel tank of the engine is disposed in the floor. An opening is formed in the top plate of the fuel tank so that the inside can be seen, and a lid is attached to the opening. The fuel tank is formed integrally with the floor pedestal, and is formed separately from the floor pedestal, and the top plate is also used as the floor slab of the floor pedestal, Sometimes it is detachably attached to the side plate of the tank.

以上説明したように、本発明は、蓋を開けた開口部から燃料タンクの内部が目視可能であるから、洗浄作業時にタンクの底部に溜まった土砂等の不純物を完全に取り去ることができる。また、燃料タンクの天板を着脱可能とすることにより、洗浄作業時に天板を取り外せば、燃料タンクの内部を容易に洗浄することができる。   As described above, according to the present invention, since the inside of the fuel tank can be visually observed from the opening having the lid opened, impurities such as earth and sand accumulated at the bottom of the tank during the cleaning operation can be completely removed. Further, by making the top plate of the fuel tank detachable, the inside of the fuel tank can be easily cleaned if the top plate is removed during the cleaning operation.

以下、本発明を図面に示される各実施形態例に基づいて説明する。図1乃至図3は本発明の第1実施形態例を示すもので、エンジン作業機1は、エンジン2と、該エンジン2により駆動される発電機、ウエルダー、コンプレッサー、油圧ユニット等の動力供給源3とを床台4上に搭載し、前記エンジン2及び前記動力供給源3をケーシング5で覆っている。   Hereinafter, the present invention will be described based on each embodiment shown in the drawings. 1 to 3 show a first embodiment of the present invention.

It is formed on the left side portion of the fuel tank 10 near the front wall 5a. These openings 19 and 20 are formed in a square shape so that the inside of the fuel tank 10 can be seen, and a lid 21 is attached thereto. The lid 21 of the opening 19 is coupled to the floor plate 7 so that it can be opened and closed on the front wall 5a side, and the opening 19 is closed by engaging the lock member 23 on the back wall 5b side. To do. Further, the lid 21 of the opening 20 is coupled to the floor plate 7 so that the back wall 5b side can be opened and closed by a hinge 22, and the opening 20 is closed by engaging the lock member 23 on the front wall 5a side. State.

このように構成することにより、燃料タンク10の洗浄作業時には、前記給油口15の蓋18及び前記開口部19,20の各蓋21をそれぞれ開けることにより、洗浄ノズルを挿入して燃料タンク10の内部を目視しながら洗浄できるから、燃料タンク10の底部に溜まった土砂等の不純物を完全に取り去ることができる。   With this configuration, when the fuel tank 10 is cleaned, the cleaning nozzle is inserted to open the fuel tank 10 by opening the lid 18 of the fuel filler opening 15 and the lids 21 of the openings 19 and 20. Since the inside can be cleaned while visually observing, impurities such as earth and sand accumulated at the bottom of the fuel tank 10 can be completely removed.

図4乃至図6は本発明の第2実施形態例を示すもので、以降の実施形態例のおいて前記第1実施形態例と同一要素には同一の符号を付して説明する。燃料タンク10は、強度を確保するために、内部に2枚の仕切り板30を設けて三等分し、第1燃料貯留室31,第2燃料貯留室32及び第3燃料貯留室33に区画している。なお、内部の仕切り板を1枚にして燃料タンクを二等分してもかまわない。前記仕切り板30は、上部の角に空気流通用の切り欠き30a,30aを、下部の角に燃料流通用の切り欠き30b、30bをそれぞれ形成している。この燃料タンク10の天板となる前記床板7には、前記第1燃料貯留室31の上部位置に前記給油口15が、前記第2燃料貯留室32の上部位置に円形の開口部34が、前記第3燃料貯留室33の上部位置に円形の開口部35がそれぞれ形成されている。両開口部34,35には、それぞれ蓋18が螺着されている。   FIGS. 4 to 6 show a second embodiment of the present invention. In the following embodiments, the same elements as those in the first embodiment will be described with the same reference numerals.
