Auxiliary Tillage Implement Control for Foldable Wings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Auxiliary tillage implements often interfere with the folding process of main tillage implements during transportation, as they are not easily compatible with the folding mechanism.
Innovation Solution
A control system that allows independent positioning of auxiliary implements on foldable sections of the tillage implement, using actuators and pivotal arms to move them out of the way during the folding process, ensuring they do not interfere with each other or the main implement.

Engineering Contradiction Analysis
1Productivity
If auxiliary implements are coupled to foldable wing sections, then multiple functions can be performed simultaneously, but the auxiliary implements interfere with the folding process during transportation
Solution Approach 1:
The auxiliary implement is made dynamically adjustable through a control system that independently positions the implement during folding operations. The control system actuates the auxiliary implement to assume different positions based on whether the implement is in field mode or transport mode, resolving the conflict between maintaining functionality during operation and compatibility during folding.
Solution Approach 2:
The control system performs preliminary positioning of the auxiliary implement before the folding process begins. By detecting when the wing section is being folded and pre-positioning the auxiliary implement out of the folding path, the system prevents interference before it occurs, enabling smooth folding operations.
2Adaptability or versatility
If auxiliary implements are positioned to avoid interference during folding, then transport compatibility is improved, but additional control mechanisms are required
Solution Approach 1:
The control system serves multiple functions: it positions the auxiliary implement during folding operations, maintains proper positioning during field operations, and coordinates with the foldable wing section mechanisms. This multi-functional approach consolidates control capabilities rather than adding separate dedicated mechanisms for each function.
Solution Approach 2:
The control system incorporates feedback mechanisms that detect the position and folding state of the wing section, then automatically adjust the auxiliary implement positioning accordingly. This feedback loop eliminates the need for complex manual control mechanisms by using automated sensing and response.

AI summary
An agricultural tillage implement includes a main section including a hitch extending in a travel direction, a plurality of foldable wing sections coupled with the main section, at least one auxiliary implement assembly coupled to each of the wing sections and a control system. Each auxiliary implement assembly includes at least one support member, at least one pivotal arm pivotally coupled to the support member, at least one actuator coupled to both the support member and the pivotal arm and a ground contacting implement coupled to the pivotal arm. The control system is configured to actuate the actuators to control a position of each ground contacting implement in each of the sections when the agricultural implement is transitioning to a transport mode.
