[0051] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These embodiments should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0052] This utility model provides an excavator after-processing system.

[0053] like Figures 1 to 9 As shown, the excavator after-processing system includes:

[0054] The main pump chamber mounting frame and the post-treatment protective cover 10 are provided. The main pump chamber mounting frame includes a support platform, and multiple vertical protective cover brackets 33 are provided on the support platform. The post-treatment protective cover 10 is fixed to the main pump chamber mounting frame through the multiple protective cover brackets 33.

[0055] In this embodiment of the invention, the post-processing protective cover 10 is used to cover the post-processing device 20. Its simple structure reduces reliance on molding dies, enhances manufacturing convenience, and lowers costs. The load-bearing platform of the main pump chamber mounting bracket can not only support the post-processing device 20 but also be used to install the main pump chamber door. In other words, the load-bearing platform can also be called the main pump chamber door mounting bracket. By integrating the main pump chamber door mounting bracket and multiple protective cover supports 33, the post-processing protective cover 10 can be directly installed through the multiple protective cover supports 33, reducing reliance on manufacturing fixtures and providing high structural strength and extended service life.

[0056] Here, the multiple protective cover brackets 33 are connected to the load-bearing platform by welding.

[0057] As an optional embodiment, the load-bearing platform includes:

[0058] The load-bearing plate 32 and the mounting frame 31 are provided. The load-bearing plate 32 is disposed on the mounting frame 31. The load-bearing plate 32 is used to support the post-treatment device 20, and the load-bearing plate 32 and the mounting frame 31 form a space for accommodating the main pump.

[0059] Optionally, the load-bearing plate 32 includes:

[0060] Three bends 321 overlap with the mounting frame 31.

[0061] It should be noted that, compared with the welding process, the load-bearing plate 32 and the mounting frame 31 are connected by a three-sided bending and overlapping process, which reduces the impact of welding deformation on flatness and further ensures the flatness requirements of the post-processing device 20.

[0062] It should also be noted that the surface of the load-bearing plate 32 is provided with a mounting plate 322, through which the post-processing device 20 is fixedly mounted on the load-bearing plate 32.

[0063] As an optional embodiment, the post-processing protective cover 10 includes:

[0064] The bending plate 111, the left side plate 112, and the right side plate 113 are bent to form three protective plates connected in sequence. The left side plate 112 and the right side plate 113 are arranged opposite to each other on both sides of the bending plate 111 and are respectively connected to the three protective plates to form a space for accommodating the post-processing device 20.

[0065] In this embodiment of the utility model, a bending plate 111 is bent to form three sequentially connected protective plates, which can be referred to as the front protective plate, the top protective plate, and the rear protective plate, respectively.

[0066] In this way, a bending plate 111 is bent to form three sequentially connected front protective plate, top protective plate and rear protective plate. Compared with the existing technology that uses three plates to make the front protective plate, top protective plate and rear protective plate respectively, the edge arc plate between the two plates is eliminated, the dependence on forming mold is reduced, the manufacturing is more convenient and the material cost is reduced.

[0067] As an optional embodiment, the bending plate 111 and the left side plate 112 are respectively provided with connectors 120 that are fixedly connected to the protective cover bracket 33.

[0068] In this embodiment of the invention, the connector 120 can be connected to the protective cover bracket 33 using a screw connection. The connector 120 securely connects the post-processing protective cover 10 to the protective cover bracket 33, ensuring structural stability.

[0069] As an optional embodiment, the first protective plate is provided with an opening 114 for the exhaust tailpipe 21 to pass through, and an inner lining plate 115 is provided on the inner side of the first protective plate at the opening 114.

[0070] In this embodiment of the invention, the exhaust tailpipe 21 is connected to the aftertreatment device 20 and is used to discharge the exhaust gas treated by the aftertreatment device 20. The first protective plate is adapted to the exhaust tailpipe 21. Here, the first protective plate is a protective plate disposed on the top surface of the aftertreatment protective cover 10, i.e., a top protective plate.

[0071] The inner lining plate 115 can improve the structural strength of the opening 114 and prevent cracking, breakage, fracture and other damage that may occur during long-term use of the opening 114.

[0072] It should be noted that an exhaust tailpipe protective cover 116 is also provided at the opening 114. The exhaust tailpipe protective cover 116 can prevent stones, leaves and other debris from entering the after-treatment protective cover 10, thereby ensuring the normal operation of the after-treatment device 20.

[0073] As an optional embodiment, at least one of the bent plate 111, the left side plate 112 and the right side plate 113 is provided with a reinforcing rib 117 on its inner side.

[0074] In this embodiment of the utility model, the bending plate 111 is fixedly connected to the left side plate 112 and the right side plate 113 by spot welding. Moreover, the bending plate 111 is provided with at least three reinforcing ribs 117, and the left side plate 112 and the right side plate 113 are each provided with at least two reinforcing ribs 117.

[0075] As an optional embodiment, at least one of the bending plate 111, the left side plate 112 and the right side plate 113 is provided with heat dissipation holes 118.

[0076] In this embodiment of the utility model, the top protective plate and the front protective plate of the bending plate 111, as well as one of the left side plate 112 and the right side plate 113, are respectively provided with heat dissipation holes 118 to meet the heat dissipation requirements of the post-processing device 20 during operation.

[0077] Optionally, a dustproof mesh 119 is provided on the heat dissipation hole 118.

[0078] In this embodiment of the utility model, a dustproof mesh 119 is installed on the heat dissipation hole 118 using a welding process to prevent stones, leaves and other debris from entering the post-processing chamber, thereby ensuring the normal operation of the post-processing device 20.

[0079] In summary, the excavator after-processing system described in this embodiment of the present invention features an integrated design for the protective cover bracket 33 and the mounting frame 31. The protective cover bracket 33 is directly welded to the mounting frame 31, allowing the after-processing protective cover 10 to be directly installed via the protective cover bracket 33. The after-processing protective cover 10 consists of three plates: the bent plate 111, the left side plate 112, and the right side plate 113. This reduces reliance on molding dies, enhances manufacturing convenience, and lowers material costs. Furthermore, compared to the reinforcing ribs 117 in existing technologies, the load-bearing plate 32 of the after-processing protective cover 10 is connected to the mounting frame 31 using a three-sided bending and overlapping process, which not only ensures flatness but also further improves structural strength and extends service life.

[0080] This utility model embodiment also provides an excavator, including the excavator after-processing system in the above embodiment.

[0081] In this embodiment of the utility model, the excavator after-processing system described above is used. It has a simple structure, reduces the dependence on forming molds, is easy to manufacture, has a low cost, and has high structural strength and long service life.

[0082] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
