The inlet air compartment of device and the post-processing freight space are in the top of the engine；The cabin is in the top in the post-processing cabin
Portion is equipped with top cover, has a ventilative flase floor the back part of top cover is tilting, top cover row of being equipped in front of the ventilative flase floor
Gas tail pipe is equipped with one end in the tailpipe bottom and protrudes into the small exhaust pipe in the tailpipe, the small exhaust pipe with
After-treatment device is connected.
In above-mentioned loading machine engine aftertreatment system technical solution, more specific technical solution may also is that the machine
Cabin is hinged with flank lid in the two sides in the post-processing cabin.
Further: that the front is high and the back is low is tilting on the top cover for the ventilative flase floor.
It is further: the diaphragm plate and two pieces of vertical clapboards in two sides be equipped with respectively with the flank cover inner face
The sealing strip abutted against.
Further: the sealing strip is rubber strip.
Further: the inlet air compartment is located at the front of the cabin.
It is further: to be equipped with engine radiating cover in the nacelle rear.
Refer to that cabin is equipped with the side of radiator after meaning of the invention.
By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages: 1, due to this
The inner space of cabin is divided into inlet air compartment, rear place by diaphragm plate and two pieces of vertical clapboards by loading machine engine aftertreatment system
Stowing and engine radiating cabin can carry out subdivision installation to engine, inlet duct and after-treatment device, its main feature is that by dividing
The heat that cabin generates engine, inlet duct and after-treatment device is thermally isolated, and reduces after-treatment device and generates heat pair
The influence of heat radiating system of whole machine, air-conditioning system and engine aspirating system etc.；Cabin is especially post-processed, the rear portion in cabin
Top cover is equipped with ventilative flase floor, and the top cover in front of flase floor of breathing freely is equipped with tailpipe, and is fitted in tailpipe
The small exhaust pipe being connected with after-treatment device, the small exhaust pipe of minor diameter and the tailpipe of major diameter form post-processing cabin
Negative pressure makes the hot-air for entering Cryogenic air from ventilative grid and post-processing in cabin form the heat exchange of convection tube stream, enhancing post-processing
Cabin heat dissipation effect；Cold air is constantly inhaled into after the hot-air progress heat exchange in post-processing cabin and post-processing cabin with exhaust quilt
Post-processing cabin is drawn, this process well removes the heat dissipation for post-processing cabin；The very good solution post-processing of engine
Influence of the heat that device generates to complete machine cooling system, engine intake duct and air-conditioning system has practical well
Value；2, each heat source for generating heat is thermally isolated by subdivision, of simple structure and strong practicability reduces complete machine
Cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Fig. 2 is the structural schematic diagram that the flank lid of the embodiment of the present invention is opened.
Structural schematic diagram when Fig. 3 is the flank lid closure of the embodiment of the present invention.
Specific embodiment
Below in conjunction with attached drawing, the invention will be further described:
Loading machine engine aftertreatment system as shown in Figure 1 includes cabin 1 and connecting in cabin 1 with engine 3
Radiator 4 and inlet duct 2；The inner space of cabin 1 is by one piece of diaphragm plate 1-3 and be located on diaphragm plate 1-3 two pieces
Vertical clapboard is divided into inlet air compartment, post-processing cabin and engine radiating cabin, and two pieces of vertical clapboards are respectively the first vertical clapboard 1-2 and the
Two vertical clapboard 1-4；The rear portion in engine radiating cabin is placed with radiator 4, is equipped with engine radiating cover 1-1 at 1 rear portion of cabin,
The engine 3 connecting with radiator 4 is located at the front in engine radiating cabin；It is placed with inlet air compartment and the post-processing of inlet duct 2
For freight space in the top of engine 3, inlet air compartment is located at the top of the front of cabin, post-processes freight space in the rear of inlet air compartment；Cabin
It is equipped with top cover 1-6 in the top in post-processing cabin, has ventilative flase floor the rear portion of top cover 1-6 is tilting, it is high before flase floor of breathing freely
It is low tilting on top cover afterwards；Tailpipe 1-5, tailpipe 1- are installed on top cover 1-6 in front of the ventilative flase floor
5 are located at post-processing cabin；Upper end, which is equipped with, in the bottom of tailpipe 1-5 protrudes into the small exhaust pipe 8 in tailpipe 1-5, float
The lower end of tracheae 1-8 is connected with the exhaust outlet of after-treatment device；It is opened in the cabin 1 of post-processing cabin two sides in the present embodiment
There are two windows, and are hinged with one piece of flank cover 1-7: diaphragm plate by the hinged shaft connected at edge above each window respectively
1-3 and the first vertical clapboard 1-2 and the second vertical clapboard 1-4 offset in the inner face that two sides are respectively arranged with respectively with flank cover 1-7
The sealing strip connect, the sealing strip of the present embodiment are rubber strip.
It, can be to hair since the inner space of cabin is separated into inlet air compartment, post-processing cabin and engine radiating cabin when work
Motivation, inlet duct and after-treatment device carry out subdivision installation, the heat generated to engine, inlet duct and after-treatment device
It is thermally isolated；And since the small exhaust pipe of minor diameter and the tailpipe of major diameter make to post-process cabin formation negative pressure, make from saturating
The hot-air that gas grid enters Cryogenic air and post-processes in cabin forms convection tube heat, enhances the effect that post-processing cabin heat distributes
Fruit；Cold air is constantly inhaled into after the hot-air progress heat exchange in post-processing cabin and post-processing cabin and is brought out post-processing with exhaust
Cabin, this process well remove the heat dissipation for post-processing cabin；What the after-treatment device of very good solution engine generated
Influence of the heat to complete machine cooling system, engine intake duct and air-conditioning system has good practical value.
