Embodiment
In order to realize following object, namely the desired volume of service tank is guaranteed, and effectively apply flexibly the space on wall top thereafter, in the mode not hindering the construction planies such as hydraulic actuated excavator to run, exhaust gas after-treatment device is arranged at this space, thus improve fitting operation and the housekeeping operation of this exhaust gas after-treatment device, the invention provides a kind of diesel motor that adopts as prime mover, and the construction plant exhaust device layout of exhaust gas after-treatment device is set in the vent systems of this diesel motor, it is by forming the recess of required size as hierarchic structure using the rear surface top of the service tank be juxtaposed in fuel pot, and described exhaust gas after-treatment device is set in the part of this recess realizes.
Embodiment 1
Below, referring to figs. 1 through Fig. 4, the preferred embodiments of the present invention are described.The present embodiment application hydraulic actuated excavator is as construction plant.First, the structure of the exhaust device layout of the construction plant involved by the present embodiment is described.Upper rotation 3 is equipped with in Fig. 1, the lower traveling body 2 in hydraulic actuated excavator 1 pivotally.Arrange operator cabin 4 at front one sidepiece of upper rotation 3, shear leg 5 can be articulated in pitching the central front portion of this upper rotation 3.Cantilever 6 can be linked rotationally up and down at the front end of this shear leg 5, up and down scraper bowl 7 can be installed rotationally at the front end of this cantilever 6.
As shown in Figure 2, form engine compartment 8 at the rear portion of upper rotation 3, the sidepiece in this engine compartment 8 is provided with diesel motor 9.This diesel motor 9 sets up cooling fan 10, and the front of this cooling fan 10 is provided with heat exchanger 11.Further, the other side in engine compartment 8, is set side by side with fuel pot 12 and service tank 13.
As shown in amplify in Fig. 3 and Fig. 4, fuel pot 12 and service tank 13 are juxtaposed on the bearing support 14 in engine compartment 8, and during top view, service tank 13 is formed as square, thereafter wall top is set to hierarchic structure, is formed the recess 13a of required size by this hierarchic structure.And exhaust gas after-treatment device 15 is set in the part of this recess 13a, is connected with baffler 16 at the rear portion of exhaust gas after-treatment device 15.
Described exhaust gas after-treatment device 15 is connected with the outlet pipe 17 from diesel motor 9.And, this outlet pipe 17 connects the liquid reducer supply tube from not shown liquid reducer tank, after liquid reducer (aqueous solution of urea) in liquid reducer tank is supplied to this outlet pipe 17, exhaust gas after-treatment device 15 plays a role as adopting the urea selective reduction type NOx treatment device of aqueous solution of urea.
In the described fuel pot 12 be set up in parallel and service tank 13, the upper part that adjoins fix each other by horn shape connector 18 and multiple bolt 19.Further, the corner section of the fuel pot 12 adjoined at the recess 13a with service tank 13 is formed with notch 12a.This notch 12a to be formed in order to the space of the setting position periphery making exhaust gas after-treatment device 15 is possessed more than needed, so be only formed at least corresponding with the recess 13a of service tank 13 side upper part.
Then, the effect of the such as exhaust device layout of the construction plant of said structure is described.That effectively applies flexibly the rear surface top of service tank 13 has space more than needed, the recess 13a of required size is formed on the rear surface top of this service tank 13, in the part of this recess 13a, exhaust gas after-treatment device 15 is set, thus the part of the rear portion of this exhaust gas after-treatment device 15 and baffler 16 can not be given prominence to from the rear portion of upper rotation 3, just exhaust gas after-treatment device 15 can be set in the mode of the operation not hindering hydraulic actuated excavator 1.
Further the recess 13a forming required size on the rear surface top of this service tank 13, during service tank 13 top view, is formed as square, even if thus also can guarantee the desired volume of service tank 13.In addition, the corner section of the fuel pot 12 adjoined at the recess 13a with service tank 13 is formed with notch 12a, thus it is further more than needed that the space of the setting position periphery of exhaust gas after-treatment device 15 can be made to possess, and makes the fitting operation etc. of this exhaust gas after-treatment device 15 become easy.
As mentioned above, in the exhaust device layout of the construction plant involved by the present embodiment, effectively apply flexibly the space on the rear surface top of service tank 13, the recess 13a of required size is formed on the rear surface top of this service tank 13, exhaust gas after-treatment device 15 is set in the part of this recess 13a, thus fitting operation and the housekeeping operation of exhaust gas after-treatment device 15 can be improved.
As described in shown in Fig. 5, the side wall surface of service tank does not form the conical surface, during top view, service tank 13 is formed as square, even if thus at the rear surface top of this service tank 13 formation recess 13a, service tank 13 also can guarantee its desired volume fully.
The corner section of the fuel pot 12 adjoined at the recess 13a with service tank 13 forms notch 12a, thus the space on the rear surface top of service tank 13 is formed further more than needed, can improve fitting operation and the housekeeping operation of exhaust gas after-treatment device 15 further.
In addition, only otherwise departing from purport of the present invention just can impose various distortion to the present invention, and the present invention also relates to the example of this distortion in the nature of things.
Utilizability in industry
Also the construction plant of beyond hydraulic actuated excavator, indispensable following functions can be applied to: the desired volume guaranteeing service tank etc., and effectively apply flexibly the space on wall top thereafter, not hinder the mode of the operation of hydraulic actuated excavator that exhaust gas after-treatment device is arranged at this space, thus improve fitting operation and the housekeeping operation of this exhaust gas after-treatment device.
