Coulter Holder Locking Linkage to Prevent Unintentional Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coulter holders in agricultural machines face issues with soil furrow formation interference between neighboring units, unintentional pivoting due to high forces, and manual actuation of locking mechanisms, leading to increased operating effort.
Innovation Solution
A coulter holder with an integrated actuating element that functions as both a pivot and locking mechanism, allowing user-friendly actuation, and includes a movable pivot bearing, a locking lever, and a hook-shaped locking element for secure and automatic locking, ensuring consistent furrow depth and reduced manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism with manual actuation is used to prevent unintentional pivoting, then reliability is improved, but ease of operation deteriorates due to increased manual effort
Solution Approach 1:
The locking mechanism is designed to be automatically actuated by the actuating element itself during the pivoting operation. When the actuating element moves the coulter connection from the raised position to the working position, it automatically triggers the locking mechanism to engage, eliminating the need for separate manual locking actions and reducing operating effort while maintaining reliability
2Stability of the object's composition
If the coulter connection is locked relative to the frame connection, then stability is improved, but ease of operation deteriorates due to complex locking procedures
Solution Approach 1:
The locking mechanism is integrated with the actuating element such that the pivoting action and locking action are combined into a single operational sequence. The actuating element simultaneously performs the function of positioning the coulter connection and triggering the locking mechanism, merging two previously separate operations into one unified action that simplifies the overall operation while ensuring stable fixation

AI summary
A coulter holder having a frame connection for attaching to a machine frame and a coulter connection for attaching a coulter unit, wherein the coulter connection is pivotable relative to the frame connection between a working position and a raised position about a pivot axis via an actuating element and is lockable relative to the frame connection via a locking mechanism for fixing the coulter unit in the working position, wherein the locking mechanism is operatively connected to the actuating element and can be actuated by actuating the actuating element.
