Swing Link Hoe Opener for Terrain Compensation

The patent applies the dynamics principle by replacing the fixed rigid mounting with a swing link mechanism that allows controlled movement. The swing link connects the cylinder to the shank through a pivot point, enabling the cylinder to swing relative to the shank during operation. This dynamic connection provides the necessary vertical motion capability while maintaining structural simplicity, directly resolving the contradiction between device complexity and manufacturing precision.

The swing link mechanism enables dynamic adjustment of the distance between the packer wheel and ground engaging tool. As the cylinder swings during operation, it automatically adjusts the linkage geometry to maintain optimal spacing between components. This dynamic adjustment ensures adequate component clearance while compensating for terrain variations, preventing excessive force variations and maintaining force uniformity across different operating conditions.

The swing link mechanism reduces the hydraulic power requirement by utilizing dynamic mechanical advantage. During the lifting operation, as the cylinder extends, the swing link rotates about its pivot point, changing the leverage ratio throughout the stroke. This dynamic mechanical advantage allows a smaller cylinder to achieve the same lifting capability that would otherwise require a larger, more power-intensive cylinder, thereby reducing hydraulic power consumption and associated costs.
