The present invention is made in view of above-mentioned actual state, and its purpose is to provide a kind of such a working rigs: its The membrane filter for allowing air to circulate to receiving room and being filtered to the dust being contained in the air can be made appropriate Ground regeneration.

For solving the means of technical problem

The feature structure of working rig of the invention for achieving the object above is as follows:

A kind of working rig, has: Drive Section；Receiving room is set to the lower section of the Drive Section；Partition wall, by institute State the first space and second space that receiving room is divided into storage engine；Membrane filter is covered from body lateral outer side The receiving room, and allow air circulation；The radiator of the engine is arranged in first space described Between engine and the membrane filter；First pressure fan is arranged in first space in the engine and institute It states between radiator, and can blow towards the radiator；In the body lateral outboard portion of the partition wall, it is provided with The connector that first space is connected to the second space.

According to above structure, the air sucked to the first space of receiving room and second space is filtered by membrane filter. Therefore, the first space keeps cleaning, and the radiator in the first space etc. will not be by dust pollution.Identical as the first space, second is empty Between also keep cleaning.

According to above structure, a part of the first pressure fan towards the air that membrane filter blows is direct from the first space It is blown into membrane filter, passes through membrane filter from the first space towards outside.As a result, in membrane filter to first The filter-portion (hereinafter sometimes referred to " the first membrane filter portion ") that the air of space sucking is circulated is regenerated.

According to above structure, another part of the first pressure fan towards the air that membrane filter blows passes through partition wall Connector enters second space from first spatial flow.The air for flowing into second space is external by dust-proof from second space direction Filter.The filter-portion to be circulated as a result, to the air sucked to second space in membrane filter (is sometimes referred to as below For " the second membrane filter portion ") it is regenerated.

Therefore, according to above structure, can make that air is allowed to circulate to receiving room and to the dust being contained in the air The membrane filter being filtered suitably regenerates.That is, any in the first membrane filter portion and the second membrane filter portion The blocking of person can remove as needed.Strainability and venting capability that membrane filter is played stably as a result,.Separately Outside, second space can be made to stably keep cleaning together with the first space, additionally it is possible to which setting is relative to scattered in second space Heat exchanger (for example, condenser of the air-conditioning of the driver's cabin of body) that hot device is separately set etc..

Another feature structure of working rig of the invention is: the partition wall has the self-filtering for allowing air circulation Device, the internal ramp is relative to the connector disassembly ease.

Inside is utilized when air flows to another one from one of the first space or second space according to above structure Filter filters the air.Even if another as a result, in the case where one of the first space or second space are by dust pollution Space also keeps cleaning.For example, the first pressure fan is blown towards membrane filter in the state that the first space is by dust pollution In the case where, it, can be by second space because being filtered from the air that first spatial flow enters second space by internal ramp Keep cleaning.In addition, internal ramp can pass through the regeneration such as disassembly cleaning in the case where blocking according to above structure.

Another feature structure of working rig of the invention is: having in the second space relative to the radiator The heat exchanger separately set and the second pressure fan for the heat exchanger, second pressure fan will be via the dustproof filters The extraneous gas of device sucking is blowed towards the heat exchanger.

According to above structure, because second space keeps cleaning, the heat exchanger separately set relative to radiator can It is used in the state of not by dust pollution.In addition, at this in use, can utilize the second pressure fan will be by membrane filter mistake The clean air of filtration is passed through heat exchanger.

Another feature structure of working rig of the invention is: first pressure fan can be via the dustproof filter Mould is changed between first action mode of device sucking extraneous gas and the second action mode blown towards the membrane filter Formula, second pressure fan stopping when first pressure fan is second action mode act.

The second pressure fan is utilized in the case where the second pressure fan acts under the first action mode according to above structure Extraneous gas is sucked via the second membrane filter portion.In the case where the second pressure fan stops under the first action mode, Pass through the sucking that connector is carried out by the first pressure fan, sucks extraneous gas via the second membrane filter portion.Therefore, In Under first action mode, the blocking of the first membrane filter and the second membrane filter is constantly carried out.

On the other hand, under the second action mode, because the second pressure fan stops and the first pressure fan is towards dustproof filter Device blows air, so a part for the air that the first pressure fan is blowed towards membrane filter is from the first space towards external logical The first membrane filter portion is crossed, another part passes through the second membrane filter portion from second space towards external by connector. As a result, under the second action mode, the first membrane filter and the regeneration of the second membrane filter.It is passed through that is, being arranged in second space In the case where the second pressure fan by membrane filter sucking extraneous gas, as long as alternately switching first acts mould at the regulation moment Formula and the second action mode etc., it will be able to regenerate the second membrane filter reliably.

Another feature structure of working rig of the invention is: the work tool is for back-stop mechanism, the back-stop mechanism Allow the air in first space to flow into the second space by the connector, and prevents the second space Interior air is flowed into first space by the connector.

According to above structure, since back-stop mechanism allows the air in the first space to flow into second space by connector It is interior, so a part for the air that the first membrane filter portion of the first pressure fan direction blows flows into second space by connector It is interior.Also, it is outside by the second membrane filter portion from second space due to entering the air in second space from first spatial flow Portion's outflow, so the second membrane filter portion can be made to regenerate.In addition, since back-stop mechanism prevents the air in second space logical It crosses connector to flow into the first space, so it is (outer to flow into the air in second space from outside by the second membrane filter portion Portion's gas) it will not be flowed into the first space by connector.Thereby, it is possible to reliably provide extraneous gas to second space.

Invention effect

Being capable of providing one kind can make that air is allowed to circulate to receiving room and carry out the dust being contained in the air The membrane filter of filtering suitably regenerated working rig.

In condenser chamber C2, the second pressure fan 38 by from the first membrane filter portion 80L suck extraneous gas and to Condenser 39 is side-blown to send (blowout) air, thus cooling condenser 39.Condenser 39 configures at the rear portion of condenser chamber C2.Second Pressure fan 38 configures between filter 33 and condenser 39.Second pressure fan 38 is discharged to the air that condenser 39 blows Space between condenser 39 and storage tank 15 (referring to Figure 20).Although the second pressure fan 38 is according to the use shape of the air-conditioning of occupant State and act (rotation), stop, but the first pressure fan 37 with the second action mode movement in the case where, the second pressure fan 38 It stops rotating.

As shown in figure 38,8 side of dust-proof shell in the hood 31 in receiving room C (body laterally right outside) setting There are spaced walls 74, spaced walls 74 have the connector 30 of connection engine room C1 and condenser chamber C2.Spaced walls 74 are positioned in cross On frame 73a, crossing frame 73a is erected between tilt frame 73 and the longitudinal framing 73b of condenser chamber C2.

Air stream in receiving room C is illustrated.As shown in figure 37, in the second pressure fan 38 under the first action mode In the case where movement, extraneous gas is sucked via the second membrane filter portion 80U using the second pressure fan 38.In the second pressure fan 38 under the first action mode in the case where stop, and sucks extraneous gas via the first membrane filter portion 80L, and pass through the The sucking that one pressure fan 37 is carried out by the internal ramp 35 of connector 30 is sucked via the second membrane filter portion 80U Extraneous gas.Therefore, under the first action mode, the blocking of the first membrane filter portion 80L and the second membrane filter portion 80U Constantly carry out.

(other embodiments)

(4) as shown in figure 39, can also have non-return valve 30a (back-stop mechanism), non-return valve 30a allows engine room C1 Interior air is flowed into condenser chamber C2 by connector 30, and the air in condenser chamber C2 is prevented to flow by connector 30 Enter in engine room C1.Non-return valve 30a is configured to close connector 30 and can be around axis swing in the front-back direction from top Opening and closing.Non-return valve 30a is exerted a force by torsional spring (not shown) to side oscillation is closed.

According to this structure, since the first pressure fan 37 is towards the one of the first membrane filter portion 80L air blowed It is partially toward non-return valve 30a flowing, so non-return valve 30a resists the active force of the torsional spring from closed state to opening side-sway It is dynamic.In this way, making the first pressure fan 37 towards the one of the first membrane filter portion 80L air blowed by opening non-return valve 30a Part is flowed into condenser chamber C2 by connector 30.On the other hand, even if air in condenser chamber C2 is towards non-return valve 30a Flowing, non-return valve 30a will not from closed state to open side oscillation.As a result, from outside by the second membrane filter portion 80U Flowing into the air (extraneous gas) in condenser chamber C2 will not be flowed into engine room C1 by connector 30.

It should be noted that " back-stop mechanism " of the invention is not limited to non-return valve 30a.It is somebody's turn to do " back-stop mechanism " and is also possible to check Mechanism other than valve 30a allows the air in engine room C1 to flow into condenser chamber C2 by connector 30 as long as it has And the air in condenser chamber C2 is prevented to flow into the function in engine room C1 by connector 30.

It should be noted that above embodiment (including other embodiments, same as below) if disclosed in structure do not produce Raw contradiction can be combined with the structure disclosed in other embodiments to use, in addition, embodiment party disclosed in this specification Formula is only example, and the implementation of the present invention is not limited to this, is able to carry out in the range of not departing from the purpose of the present invention It is appropriate to change.
