Modular Floor Assembly for Combine Header
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional header floors in agricultural cutting machines are inflexible, leading to compromised performance on uneven terrain and are difficult to maintain due to the need for partial disassembly during repairs or replacements.
Innovation Solution
A modular floor assembly comprising resiliently projected support and floor sheet modules that allow the cutterbar to flex and overlap, enabling easier movement over uneven terrain while allowing for individual module replacement without disassembling the header.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional inflexible header floor is used, then the header floor provides a smooth transition for crop flow, but the cutterbar cannot flex to match uneven terrain, compromising header performance
Solution Approach 1:
The header floor is divided into multiple replaceable floor modules that can be independently installed and removed. Each module contains a portion of the cutterbar attachment, allowing the cutterbar to flex while maintaining floor coverage. This segmentation enables the floor to adapt to terrain variations through modular replacement rather than requiring the entire floor to be rigid or fully disassembled.
Solution Approach 2:
The floor modules are designed with dynamic attachment mechanisms that allow for easy installation and removal. The cutterbar attachment portions within the modules enable the cutterbar to flex and adapt to uneven terrain while the modules themselves can be dynamically replaced without disassembling the entire header floor system.
2Ease of repair
If the header floor is attached to the cutterbar, then the floor provides crop flow transition, but repairing or replacing the floor requires disassembling a significant portion of the header, increasing maintenance time and cost
Solution Approach 1:
The floor is segmented into multiple independent modules that can be replaced individually. Each module contains a portion of the cutterbar attachment and can be removed and replaced without disassembling the entire header floor system, significantly reducing maintenance time and allowing quick replacement of damaged sections.
Solution Approach 2:
The floor modules are designed as extractable units that can be removed from the header without disassembling the entire floor system. Each module can be independently extracted and replaced, allowing maintenance personnel to quickly replace damaged modules while leaving the rest of the header assembly intact.
3Adaptability or versatility
If the header floor is made inflexible to maintain structural integrity, then the floor provides stable crop flow transition, but the cutterbar cannot flex to match the underlying terrain
Solution Approach 1:
The floor is divided into multiple modules that can be independently positioned and replaced. This segmentation allows the cutterbar attachment portions within the modules to flex and adapt to uneven terrain while maintaining overall floor integrity and stable crop flow transition across the header surface.

AI summary
A floor module (100) suitable for inclusion in the modular floor assembly (20) of a header (10) of an agricultural cutting machine comprises a support (160) and an overlaying floor sheet (120). The support (160) includes a support leading edge portion (122), a support trailing edge portion (166), and a floor support portion (170) disposed therebetween. The support leading edge (164) portion attaches to the cutter bar (50) of the header (10). The support trailing edge portion (166) includes a first resilient projection (188), and the floor support portion (170) includes a second resilient projection (200). The floor sheet (120) includes a floor sheet leading edge portion (122), a floor sheet trailing edge portion (126), and a substantially planar floor portion (130) disposed therebetween. The first resilient projection (188) and the floor sheet trailing edge portion (126) define a trailing slot (194) configured to receive a header frame projection (196). The second resilient projection (200) and the substantially planar floor portion (130) define a side slot (232) configured to receive a side edge portion (236) of an adjacent floor module (100).
