Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a multi-stage power output transmission device for a harvester. Background Technology

[0002] A transfer case is a mechanical device that distributes engine power to different power outputs and is often used in fields such as agricultural machinery.

[0003] In existing agricultural machinery transfer cases, single-stage power output is often used, resulting in low utilization of engine power. Additionally, the output and power ends are usually on the same horizontal plane, making them unsuitable for the coordinated use of some complex components. Furthermore, since agricultural machinery is typically used in relatively harsh environments, the transfer case usually needs to be as small as possible, and its sealing performance is also highly demanding to reduce the impact of environmental factors on its performance.
