Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to an exhaust gas aftertreatment device. Background Technology

[0002] As users' demands for agricultural machinery products increase, agricultural machinery is gradually developing towards a more aesthetically pleasing appearance and a more rational human-machine interaction. Therefore, box-type after-treatment systems for agricultural machinery have also been gradually developed. At present, tractor after-treatment systems mostly adopt an L-shaped structure, characterized by a large height of the after-treatment cylinder, a relatively short tailpipe gear, and high strength in the smaller tailpipe, thus eliminating the need for additional fixation of the tailpipe. However, as the layout structure of tractor after-treatment systems gradually transitions to box-type after-treatment systems, the after-treatment tailpipe becomes very long. Furthermore, the application of floating cabs makes it impossible to fix the after-treatment tailpipe to the cab pillar. How to effectively fix the tailpipe of the box-type after-treatment system for tractors is one of the problems that needs to be solved in the current development of tractors.

[0003] Therefore, it is necessary to provide a tractor exhaust aftertreatment device to overcome the defects mentioned above. Utility Model Content
