Soil Cultivation Machine Side Plate Pivot Adjustment

The patent inverts the adjustment mechanism from a translational design (prone to contamination) to a rotary design (resistant to contamination). The support arm is pivotably articulated on the pivot lever instead of being translationally adjusted, so that adjustment is achieved through rotation about a pivot axis rather than linear movement. This inversion allows the adjustment function to be achieved while minimizing exposure to soil contamination.

The patent changes the dimension of adjustment from translational (linear movement along the direction of adjustment) to rotary (circular movement around a pivot axis). By moving the support arm in an arc rather than in a straight line, the adjustment mechanism operates in a different dimensional space that is less susceptible to soil contamination and jamming.

The patent makes the side plate arrangement dynamically adjustable through the pivot mechanism, allowing the machine to switch between different width configurations. In working position, the support arm is rotated to maximize the distance between the side plate and tool rotors, increasing working width. In transport position, the support arm is rotated to minimize this distance, ensuring compliance with legal transport width limits.

The patent enables periodic switching between two distinct states: working position (maximum width) and transport position (minimum width). This periodic adjustment allows the machine to alternately achieve maximum productivity during field operations and compliance during transport, with the pivot mechanism facilitating quick transitions between these states.
