Tillage Frame Load Transfer to Hitch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural tillage implements with rear auxiliary tools often place excessive loading on the frame, which can lead to inefficiencies and potential damage during soil preparation.
Innovation Solution
The design incorporates a center frame section with load transfer frame members that direct additional loads from rear auxiliary implements directly to the pull hitch, distributing these loads effectively and reducing the strain on the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rear auxiliary implements are attached to the tillage implement, then additional functions are provided, but excessive loading is placed on the frame
Solution Approach 1:
The frame is segmented into a center frame section with dedicated load transfer frame members that are structurally separated from the main frame body. This segmentation allows loads from rear auxiliary implements to be isolated and directed through specific load transfer members to the pull hitch, preventing excessive loading on the main frame while preserving the ability to attach multiple auxiliary implements.
Solution Approach 2:
Load transfer frame members act as intermediary structural elements between the rear auxiliary implements and the pull hitch. These members specifically mediate the load path, transferring forces directly to the pull hitch without passing through the main frame structure, thus protecting the frame from excessive loading while enabling auxiliary implement attachment.
2Reliability
If loads from rear auxiliary implements are transferred through the frame, then structural integrity is maintained, but frame stress increases
Solution Approach 1:
The load transfer function is extracted from the main frame structure and assigned to dedicated load transfer frame members. By taking out the load-bearing function from the frame, the frame maintains its structural integrity for supporting tillage implements while the load transfer members handle the stress from rear auxiliary implements, directing it straight to the pull hitch.
Solution Approach 2:
Load transfer frame members serve as intermediary elements that create a separate load path. They mediate between the rear auxiliary implements and the pull hitch, allowing structural integrity to be maintained through proper load routing while minimizing frame stress by preventing load concentration on the frame structure.
3Force
If the frame structure is reinforced to handle additional loads, then load capacity increases, but device complexity increases
Solution Approach 1:
Rather than reinforcing the entire frame structure, the solution segments the load handling function into specific load transfer frame members. This segmentation allows load capacity to be increased for rear auxiliary implements without adding complexity to the overall frame design, as only specific members are designed for load transfer while the rest of the frame remains simple.
Solution Approach 2:
The load transfer function is merged with the existing frame members by designing load transfer frame members that are attached to the center frame section. This merging approach increases load capacity without creating entirely separate structures, thereby avoiding excessive complexity while achieving the desired force handling capability.

AI summary
An agricultural tillage implement includes a center frame section having a front frame member extending transverse to a travel direction, a rear frame member extending transverse to the travel direction, and a plurality of longitudinal frame members extending from and attached between the front frame member and the rear frame member. The plurality of longitudinal frame members include a pair of side frame members positioned at respective sides of the center frame section, and a pair of load distribution frame members. A plurality of tillage implements extend downwardly from the center frame section. A pull hitch is directly attached to the front frame member at two attachment locations and extends forward from the center frame section in the travel direction. Each attachment location is aligned with a respective load distribution frame member.
