Agricultural Soil Cultivation Unit Online Depth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural soil cultivation units experience diagonal pull due to unequal transverse forces between soil working tool rows, which is difficult to adjust and laborious to compensate, especially under changing soil conditions.
Innovation Solution
An adjustable working depth setting system that allows online adjustment of soil working tool rows relative to each other, using an actuator actuated by external energy, to compensate for side forces and prevent diagonal pull, with manual, semi-automatic, or fully automatic control options, and integration with detection means for real-time adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the trailing soil working tool row travels at a larger working depth to compensate for unequal transverse forces, then the diagonal pull is reduced, but the adjustment becomes complex and laborious
Solution Approach 1:
The patent implements dynamic adjustment of working depths by making the tool rows vertically adjustable relative to one another during operation. This allows the system to adapt to changing soil conditions and maintain force balance without fixed complex mechanical adjustments, resolving the contradiction between stability and device complexity.
Solution Approach 2:
The patent changes the working depth parameter of tool rows dynamically based on detected transverse forces. By varying this parameter in response to actual operating conditions, the system achieves force balance without requiring complex pre-adjustment mechanisms, thus reducing adjustment complexity while maintaining stability.
2Stability of the object's composition
If manual adjustment of working depths is performed to compensate for diagonal pull, then force balance is achieved, but operator effort and time consumption increase
Solution Approach 1:
The patent employs detection means that continuously monitor transverse forces and feed this information back to the control system. This automatic feedback loop eliminates the need for manual observation and adjustment by the operator, reducing both time loss and operator effort while maintaining force balance through real-time corrections.
Solution Approach 2:
The system performs self-adjustment of working depths based on detected force imbalances. The automatic control system independently manages the vertical positioning of tool rows without requiring operator intervention, thereby eliminating the time and effort previously spent on manual adjustments while maintaining stable force balance.
3Adaptability or versatility
If the tool rows are lifted and lowered during operation, then headland maneuverability is enabled, but the previously adjusted working depth settings are displaced
Solution Approach 1:
The detection means continuously monitor transverse forces even during lifting and lowering operations. This continuous feedback allows the control system to detect any displacement in working depth settings caused by headland maneuvers and automatically compensate for it, maintaining both adaptability for headland positions and stability of working depth settings.
Solution Approach 2:
The system performs preliminary detection of force imbalances before they significantly affect operation. By continuously monitoring and making proactive adjustments, the system prevents working depth setting displacement rather than merely reacting to it, thus maintaining stability while enabling headland maneuverability.

AI summary
An agricultural soil cultivation unit having at least two rows of soil working tools that are fastened to a tool carrying frame that is pivotably supported about a horizontal frame pivot axis at a machine frame supported by a chassis on the ground and liftable by a lifting apparatus into a headland position and/or transport position. It is therefore proposed in accordance with an aspect of the invention to change the working depth setting of the soil working tool rows relative to one another online in working operation to hereby be able to react to changing soil conditions in working operation and to be able to mutually compensate resulting side forces of the soil working tools.
