Description

Technical Field

[0001] This utility model relates to the field of double-disc cutting table technology, specifically a universal joint transmission protection mechanism for a double-disc cutting table. Background Technology

[0002] The dual-disc header, a crucial component of combine harvesters, primarily functions to cut crops with blades, ensuring both harvest efficiency and quality. During harvesting, the universal joint, a core component of the transmission system, plays a vital role. By connecting different parts, the universal joint ensures power transmission and the normal operation of the header. However, existing universal joint transmission systems often suffer from stability issues and lack sufficient protective functions, leading to frequent equipment damage and malfunctions, severely impacting harvesting efficiency and equipment lifespan.

[0003] During the operation of a dual-disc cutting table, the universal joint needs to withstand significant power transmission pressure and frequent rotational loads. However, existing universal joint designs are prone to unstable rotation and severe vibration under high loads and complex terrain. This unstable transmission state not only affects the working accuracy of the cutting table but may also lead to excessive wear of the transmission system, or even malfunctions such as breakage or jamming.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a universal joint transmission protection mechanism for a double-disc cutting table. Utility Model Content
