Agricultural Closing Tool Dynamic Repositioning for Soil Buildup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural implements face material accumulation issues, such as soil and residue buildup, which can prevent closing tools from properly closing furrows, affecting yield and efficiency.
Innovation Solution
A system and method that utilize actuators and controllers to move closing tools between working and material removal positions, adjusting their lateral and vertical spacing to reduce material accumulation, with sensors detecting accumulation and triggering these adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If closing tools are kept in fixed working position, then furrow closure function is maintained, but material accumulation builds up and prevents proper operation
Solution Approach 1:
The closing tools are made dynamically adjustable between a working position for furrow closure and a material removal position for clearing accumulation. The system transitions from static fixed positioning to dynamic repositioning based on operational needs, allowing the tools to adapt their position to maintain reliable furrow closure while preventing material buildup that would otherwise interfere with operation
Solution Approach 2:
The system changes the positional parameters of the closing tools by moving them between predetermined working and material removal positions. This parameter change approach allows the same tool to perform different functions (furrow closure vs. material removal) by adjusting its position, thereby maintaining reliability while eliminating material accumulation harm
2Object-generated harmful factors
If closing tools are moved to material removal position, then material accumulation is reduced, but furrow closure operation is interrupted
Solution Approach 1:
The system implements periodic action by alternating between furrow closure operations and material removal actions. The closing tools periodically transition to material removal position to clear accumulation, then return to working position to resume furrow closure. This periodic cycling prevents continuous operation interruption while systematically eliminating material buildup that would otherwise stop production
Solution Approach 2:
The material removal position transitions are executed as brief skipping actions rather than prolonged interruptions. The system quickly moves tools to remove material and immediately returns to working position, minimizing the time spent out of production mode. This allows the harmful material accumulation to be addressed rapidly without significantly impacting overall furrow closure productivity
3Object-generated harmful factors
If manual monitoring and adjustment of closing tools is used, then material accumulation can be managed, but labor requirements and operational complexity increase
Solution Approach 1:
The system employs feedback mechanisms where sensors detect material accumulation conditions and automatically trigger controller responses to reposition closing tools. This closed-loop feedback control eliminates the need for manual monitoring while managing material accumulation, and the automated nature actually reduces overall system complexity compared to manual operation requirements
Solution Approach 2:
The closing tools are equipped with self-service capabilities through automated detection and actuation systems. The system monitors its own operational conditions (material accumulation) and autonomously adjusts its position without external manual intervention. This self-service approach manages material accumulation while simplifying operation rather than increasing complexity

AI summary
In one aspect, a method for reducing material accumulation relative to a closing assembly of an agricultural implement may include receiving an input associated with an amount of material accumulation relative to the closing assembly. Additionally, the method may include controlling an operation of the implement based on the received input such that at least one of a first closing tool or a second closing tool of the closing assembly moves from a working position to a material removal position to reduce an amount of material accumulation relative to the closing assembly. The method may also include controlling an operation of an actuator of the implement to actuate the at least one of the first closing tool or the second closing tool from the material removal position back to the working position.
