The specific embodiment
Below, describe with reference to the Fuel Tank of accompanying drawing the construction machinery and equipment of the utility model.
With reference to Fig. 1, possess: bottom driving body 2 that can be voluntarily as the hydraulic excavator 1 of construction machinery and equipment; And the upper rotating body 6 that is placed on these bottom driving body 2 tops by means of rotating mechanism.Rotating mechanism for example is a revolving wheel 4, and upper rotating body 6 can be rotated with respect to bottom driving body 2 by means of this revolving wheel 4 and is installed in freely on the bottom driving body 2.The apparatus for work 9 that is provided with operator's compartment 8 in the front portion of this upper rotating body 6 and operates by this operator's compartment 8.This apparatus for work 9 also has the hydraulic actuating cylinder that makes these parts work except the scraper bowl 14 of the front end of crane arm 10, arm 12 and this arm 12.
In addition, at the rear portion of upper rotating body 6, dispose engine room 16 at the rear of operator's compartment 8.Folding and unfolding has driving engine (not shown) and Hydraulic Pump (not shown) etc. in this engine room 16.Hydraulic Pump is driven by driving engine, and to the hydraulic actuating cylinder of apparatus for work 9 and going with supply power fluides such as motors of bottom driving body 2.Have, dispose counterweight 18 at the rear portion of upper rotating body 6, this counterweight 18 is stablized its work posture when hydraulic excavator 1 work.
And, on the top of upper rotating body 6, near driving engine, be provided with case apparatus 19.This case apparatus 19 has: the operating oil tank that stockpiles above-mentioned power fluid; And the Fuel Tank 20 that stockpiles engine fuel.
Below, with reference to Fig. 2～Fig. 4, the Fuel Tank 20 of the construction machinery and equipment of the utility model is carried out detailed explanation.
The Fuel Tank 20 of the construction machinery and equipment of the utility model possesses box main body 22.Box main body 22 is box shapes, is used to stockpile fuel.In box main body 22, be extended with oil supply line 24.An end of oil supply line 24 extends to box main body 22 and forms oil-feed port 26 outward.Another end of service 24 forms discharge orifice 28 at box main body 22 inner openings.When fuel being stockpiled in the box main body 22, carry out from oil-feed port 22 fuelings and from discharge orifice 28 discharge fuel.In addition, supply port 26 covers (with reference to Fig. 2, Fig. 3) by lid 30.In addition, oil-feed port 26 also can be formed on the surface of box main body 22.
On oil supply line 24, dispose filter chamber 44.This filter chamber 44 is the parts in encirclement and oil supply line 24 bonded assembly spaces, specifically is the part that folding and unfolding is used for the fuel filter 50 of filtering fuel.In order to make this filter chamber 44 and external communications, be formed with the replacement port 38 that connects box main body 22.Fuel filter 50 can take out and put into respect to filter chamber 44 through this replacement port 38.Specifically, fuel filter 50 is the hollow cylinder shape.The material of filter of acting as a fuel can be suitable for various materials.In addition, replacement port 38 is covered by lid 48.
The operating personnel turns on the lid 30 of oil-feed port 26 in fuel feeding to Fuel Tank 20 time, oil-feed port 26 is exposed, and the fuel feeding nozzle of fuel lead (not shown) is inserted in the oil supply line 24 from oil-feed port 26.Shown in the arrow A of Fig. 4, supply with the fuel that comes from the fuel feeding nozzle and in box main body 22, discharge in oil supply line 24 circulations and from the discharge orifice 28 of oil supply line 24.At this moment, the inboard circulation from the lateral of fuel filter 50 is filtered by fuel filter 50 in the filter chamber 44 of fuel in oil supply line 24, removes impurity.
In embodiment illustrated, as can knowing clearly that with reference to Fig. 4 be provided with filter chamber 44 in the end of oil supply line 24,44 lower end is formed with discharge orifice 28 in the filter chamber.In addition, replacement port 38 is formed on the upper face of box main body 22.Like this, if replacement port 38 is formed on the upper face of box main body 22, then can fuel filter 50 be taken out from the top of Fuel Tank 20.Therefore, can common safeguard posture, promptly take the replacing operation of under the state of vehicle body upper portion, carrying out fuel filter 50, so operation becomes easy.Have again, also can refuelling filter 50 under the state of fuel even in Fuel Tank 20, stockpiled.
As above state brightly,, so can make fuel filter 50 not receive restrictedly being configured of installing space of the vehicle body upper portion of construction machinery and equipment because fuel filter 50 is arranged on to box main body 22 in the filter chamber 44 in the oil supply line 24 that extends.Promptly, because fuel filter 50 is configured in the box main body 22, therefore can effectively utilize the spaces in the box main body 22 and high capacity and the big fuel filter 50 of open area are set.Therefore, the replacement cycle of fuel filter 50 can be prolonged, the efficient of upkeep operation can be improved.In addition, owing to can therefore utilize the replacing of the fuel filter 50 of replacement port 38 easily, also easily fuel filter 50 is arranged in the filter chamber 44 from replacement port 38 refuelling filters 50.
Though more than be through with to the explanation of the embodiment of the utility model, the utility model is not limited to above-mentioned embodiment, can in the scope of the embodiment that does not break away from the utility model, carry out various distortion.
For example, as shown in Figure 5, also can replacement port 38 be also used as oil-feed port 26.At length say, on oil supply line 24, set the outstanding pipe 27 of the tubulose of both ends open.Should for example be configured coaxially with replacement port 38 in the replacement port 38 by outstanding pipe 27.An end of outstanding pipe 27 connects outside box main body 22 covers the extension of 48 ground, thereby forms oil-feed port 26.Oil-feed port 26 is covered by lid 30.In addition, outstanding pipe 27 is integrally formed with lid 48.Another end (being the inboard of fuel filter 50 in Fig. 5) opening in filter chamber 44 of outstanding pipe 27.In this case, the fuel of being supplied with via outstanding pipe 27 from oil-feed port 26 flows into the inboard of fuel filter 50, circulates laterally from the inboard of fuel filter 50.In order to realize this circulation, under the situation of the fuel filter 50 of drum as shown in the figure, the inside lower end of fuel filter 50 is by the base plate that forms filter chamber 44 32 obturations.This base plate 32 is supported by the for example spoke that 44 the sidewall from the filter chamber sets up.And fuel is discharged (arrow B of Fig. 5) from the discharge orifice 28 of being located at 44 lower ends, filter chamber after being removed impurity in box main body 22.Like this, in the example of Fig. 5, replacement port 38 is also used as oil-feed port 26, and oil supply line 24 can also dual-purpose with filter chamber 44 thus.Like this, if dual-purpose oil-feed port 26 and replacement port 38 then can effectively utilize the space in the box main body 22 and high capacity and the big fuel filter 50 of open area are set with simple structure.Therefore, the replacement cycle of fuel filter 50 can be prolonged, the efficient of upkeep operation can be improved.In addition, when refuelling filter 50, cover 48 outstanding pipe 27 is broken away from lid 48 as long as turn on, therefore can be under the state that discharge orifice 38 is exposed fully, easily the refuelling filter 50.In addition, also can protrusion 27 and lid 48 be made split, dismantle respectively.
In addition, be also used as at replacement port 38 under the situation of supply port 26, also can outstanding pipe 27 be set and from replacement port 38 direct fuelings at oil supply line 24 clocks.
In addition, the shape of fuel filter 50 is not limited to drum, so long as the shape that can be configured in the Fuel Tank 20 gets final product.
