Mountable Furrow Closing Assembly With Four-Linkage Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closing wheels in agricultural seeding machines are inefficient as they rely heavily on operator input and often fail to fully close the furrow, leaving seeds exposed to the elements, and lack universality across different agricultural implement manufacturers.
Innovation Solution
A system featuring a cast arm design with asymmetrically shaped components and a four-linkage mechanism that includes closing wheels, a compaction wheel, and a fertilizer tube, which can be universally mounted on various agricultural implements, providing self-correction and consistent down pressure to ensure proper furrow closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional closing wheels are used, then the structure is simple, but the furrow closure effectiveness deteriorates due to reliance on operator input and inability to fully close the furrow
Solution Approach 1:
The closing assembly is designed to automatically regulate its own operation through the four-linkage mechanism that responds to furrow conditions. The system self-corrects without operator intervention by using the linkage geometry to automatically adjust closing wheel position and pressure based on the furrow state, making the system self-sufficient and reliable.
Solution Approach 2:
The four-linkage mechanism provides dynamic adaptation to varying furrow conditions. The linkage allows the closing wheels to move and adjust their position and applied force dynamically in response to changes in furrow depth, soil conditions, and resistance, ensuring consistent closure effectiveness across different operating conditions.
2Productivity
If closing wheels rely on operator input, then the device complexity is low, but the productivity deteriorates due to incomplete furrow closure and seed exposure
Solution Approach 1:
The system performs furrow closure automatically without requiring operator attention or adjustment. The four-linkage mechanism and closing wheels work autonomously to complete the closure function, freeing the operator to focus on other aspects of machine operation and increasing overall productivity.
Solution Approach 2:
The linkage mechanism provides mechanical feedback from the furrow closure process back to the operator through the structure's movement and force requirements. The system responds to closure resistance and furrow conditions, automatically adjusting its operation based on real-time feedback from the field conditions.
3Adaptability or versatility
If closing wheels are used without universal mounting capability, then the design can be optimized for specific implements, but the adaptability deteriorates across different agricultural implement manufacturers
Solution Approach 1:
The closing assembly is designed with universal mounting capabilities that allow it to be installed on various agricultural implements from different manufacturers. The mounting system incorporates standardized interfaces and adjustable components that can accommodate different implement types while maintaining consistent closure performance.
Solution Approach 2:
The assembly is divided into modular components including the mounting mechanism, linkage system, and closing wheels that can be independently adjusted or replaced. This segmentation allows the same basic design to be adapted to different implement configurations without redesigning the entire system.

AI summary
A mountable furrow closing assembly is integrated into a system for closing a furrow including a frame having a forward end and a rearward end and closing wheels. A method utilizing the system to operate an agricultural implement includes opening a furrow, planting a seed in the furrow, and closing the furrow with the system. The system may be assembled by removing existing closing wheels from a first location of a frame of an agricultural implement, operatively attaching the closing wheels at a second location of the frame, and operatively attaching the mountable furrow closing assembly at the first location of the frame.
