Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment, and in particular to a novel off-road sunken arrangement after-treatment device. Background Technology

[0002] Non-road vehicles mainly include agricultural machinery (such as tractors), construction machinery (such as excavators), off-road vehicles, etc., and are used on unpaved roads such as farmland, construction sites, and forest areas.

[0003] With the continuous upgrading of non-road emission regulations, the requirements for pollutants emitted by non-road vehicles are becoming increasingly stringent, and the requirements for exhaust aftertreatment performance are also becoming increasingly higher. In order for products to meet the requirements and be applicable to different vehicle models, it is necessary to have reliable and stable product structure, as well as an aesthetically pleasing overall appearance that does not obstruct the driver's view. Existing exhaust aftertreatment systems are traditional vertical cylindrical structures with low structural strength. Due to their large overall diameter, they also obstruct the driver's view to a certain extent.

[0004] Therefore, it is necessary to provide a new type of off-road sunken post-treatment device to solve the above problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a novel non-road sunken layout post-treatment device that avoids obstructing the view and increases structural strength.

[0006] To solve the above-mentioned technical problems, the present invention provides a novel off-road sunken aftertreatment device comprising: a protective cover consisting of a front panel, side panels, a bottom panel, a top panel, and a back panel; inside the protective cover, a DOC assembly, a DPF assembly, a mixer assembly, and an SCR and ASC assembly are sequentially installed, and the sequentially connected DOC assembly, DPF assembly, mixer assembly, and SCR and ASC assembly are arranged in a "U" shape inside the protective cover; an air intake pipe is installed on the side wall of the side panel, and the air intake pipe is connected to the DOC assembly; an exhaust pipe is installed on the side wall of the top panel, and the exhaust pipe is connected to the interior of the SCR and ASC assembly.

[0007] Preferably, the surface of the top plate is arc-shaped, a protective cylinder is installed on one side of the top plate, and the protective cylinder wraps around the surface of the exhaust pipe.

[0008] Preferably, the surfaces of the side panel and the panel are provided with multiple heat dissipation grooves at an angle, and the surfaces of the side panel and the panel are provided with multiple cover plates with arc-shaped sidewalls, and the cover plates cover the bottom of the heat dissipation grooves.

[0009] Preferably, the panel, the side panel, the bottom plate, the top plate, and the back plate are fixed together by bolts.

[0010] Preferably, both the base plate and the back plate have multiple mounting holes on their surfaces for connection with off-road vehicles.

[0011] Preferably, the bottom surface of the base plate is symmetrically provided with grooves, and a rubber pad is placed inside the grooves; the bottom surface of the rubber pad is provided with a plurality of protrusions with arc-shaped sidewalls, and the bending directions of adjacent protrusions are different.

[0012] Compared with related technologies, the novel off-road sunken post-treatment device provided by this utility model has the following beneficial effects:

[0013] This utility model provides a novel off-road sunken aftertreatment device. The DOC component, DPF component, mixer component, and SCR and ASC components are arranged in a "U" shape inside the protective cover, concentrating the overall structural center of gravity at the bottom. This is a non-traditional vertical cylindrical structure, allowing it to be placed at the bottom of the cab, i.e., a sunken layout scheme, with only the exhaust tailpipe protruding. This facilitates compatibility with more vehicle models and significantly improves driving visibility and safety. The protective cover and protective cylinder enclose the entire structure, effectively preventing the risk of fire caused by flammable materials such as weeds entering the aftertreatment system during operation. It also enhances the overall aesthetics, as the internal components are not directly exposed, extending the aftertreatment system's service life. The aftertreatment device is fixed to the vehicle using bottom and side mounting holes, facilitating installation and disassembly. Once fixed, the structure boasts high strength and extended service life. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1 to 4 , Figure 1 A schematic diagram of a preferred embodiment of the novel off-road sunken post-treatment device provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the protective cylinder. Figure 3 for Figure 1 The diagram shows the base plate structure. Figure 4 for Figure 1 The diagram shows the internal structure of the base plate. A novel off-road sunken aftertreatment device comprises a protective cover consisting of a panel 2, side panels 3, a base plate 4, a top plate 8, and a back plate 13. Inside the protective cover, a DOC assembly 9, a DPF assembly 10, a mixer assembly 11, and an SCR and ASC assembly 12 are sequentially installed, arranged in a U-shape. An air intake pipe 1 is installed on the side wall of the side panel 3, and the air intake pipe 1 is connected to the DOC assembly 9. An exhaust pipe 7 is installed on the side wall of the top plate 8. 7 is connected to the interior of the SCR and ASC assembly 12. The exhaust gas generated by non-road vehicles enters the interior of the DOC assembly 9, DPF assembly 10, mixer assembly 11 and SCR and ASC assembly 12 in sequence through the intake pipe 1. The DOC assembly 9 can intercept more than 95% of black smoke particles. The DPF assembly 10 removes harmful gases such as CO and HC through oxidation reaction. Urea is mixed with the exhaust gas in the mixer assembly 11. The SCR and ASC assembly 12 generates harmless N2 and HO2 under the action of catalyst, thereby purifying the exhaust gas. The purified exhaust gas is discharged through the exhaust pipe 7.

[0021] The DOC component 9, DPF component 10, mixer component 11, and SCR and ASC components 12 are arranged in a "U" shape inside the protective cover, concentrating the overall structural center of gravity at the bottom. This non-traditional vertical cylindrical structure allows for placement at the bottom of the cab, a recessed arrangement with only the exhaust tailpipe protruding. This facilitates compatibility with more vehicle models and significantly improves driver visibility and safety. The protective cover and casing enclose the entire structure, effectively preventing the risk of ignition from flammable materials such as weeds during operation. It also enhances the overall aesthetics, as internal components are not directly exposed, extending the lifespan of the aftertreatment system. The aftertreatment unit is secured to the vehicle using bottom and side mounting holes, facilitating installation and disassembly. Once secured, the structure boasts high strength and extended durability.

[0022] The surface of the top plate 8 is arc-shaped. A protective cylinder 6 is installed on one side of the top plate 8, and the protective cylinder 6 wraps around the surface of the exhaust pipe 7. This is to facilitate the protection of the exhaust pipe 7 by the protective cylinder 6 and to allow flammable materials such as weeds to slide down the surface of the top plate 8.

[0023] Both the side panel 3 and the panel 2 have multiple heat dissipation grooves 14 inclined on their surfaces. Heat inside the protective cover is discharged through the heat dissipation grooves 14. The downwardly inclined heat dissipation grooves 14 prevent weeds from entering the interior of the heat dissipation grooves 14. The side panel 3 and the panel 2 are equipped with multiple cover plates 5 with arc-shaped sidewalls. The cover plates 5 cover the bottom of the heat dissipation grooves 14. In order to protect the heat dissipation grooves 14 and prevent impurities from entering the interior of the heat dissipation grooves 14, the cover plates 5 seal the heat dissipation grooves 14.

[0024] The panel 2, the side panel 3, the bottom plate 4, the top plate 8, and the back plate 13 are fixed together by bolts to facilitate the assembly of various materials to form a protective cover.

[0025] Both the base plate 4 and the back plate 13 have multiple mounting holes for connecting to off-road vehicles. The bottom mounting holes are fixed to the vehicle pallet, and the side mounting holes are fixed to the vehicle frame. After fixing, the protective cover has good structural strength, is suitable for different working conditions, and has a long service life.

[0026] The bottom surface of the base plate 4 is symmetrically provided with grooves 41, and a rubber pad 42 is placed inside the grooves 41. The bottom surface of the rubber pad 42 is provided with multiple protrusions 43 with arc-shaped sidewalls, and the bending directions of adjacent protrusions 43 are different. When the base plate 4 is fixed to the surface of the vehicle pallet, the rubber pad 42 inside the grooves 41 is compressed. The rubber pad 42 plays a buffering and shock-absorbing role between the vehicle and the base plate 4, reducing the vibration amplitude of the protective cover during use. Furthermore, the compression of the protrusions 43 on the bottom surface of the rubber pad 42 increases the friction between the rubber pad 42 and the vehicle. The different bending directions of adjacent protrusions 43 allow them to hook onto the surface of the vehicle from different angles, further increasing the friction and thus providing stability and firmness of the protective cover on the surface of the vehicle.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
