Down Crop Header Attachment with Ground-Driven Wheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing down corn attachments for agricultural headers are complex, cumbersome, and often increase the overall weight of the header, while lacking a cost-effective and efficient solution for gathering bent, fallen, or lodged crop material.
Innovation Solution
A header design featuring crop dividers with rotatably attached down crop gathering wheels and drive wheels that contact the field to efficiently gather down crop material without significantly increasing the header's weight, and allowing for optional removal based on operational conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a down corn attachment is added to the header, then the gathering efficiency of downed crop material is improved, but the device complexity and maintenance difficulty increase
Solution Approach 1:
The down corn attachment is divided into separate modular components: gathering chains, drive wheels, and idler wheels that can be independently assembled and maintained. Each row unit has its own dedicated components rather than a single complex mechanism serving multiple rows.
Solution Approach 2:
The drive wheels are designed to contact the ground and automatically drive the gathering chains through ground reaction force, eliminating the need for complex powered drive mechanisms. The system uses the vehicle's forward motion to power the gathering function.
2Productivity
If a down corn attachment is added to the header, then the gathering efficiency of downed crop material is improved, but the maintenance burden increases
Solution Approach 1:
The attachment features modular row units with independent gathering chains and wheels that can be accessed and maintained separately. Each chain can be serviced without disassembling the entire attachment system.
Solution Approach 2:
The gathering chains are designed to be easily removable from the header structure, allowing quick extraction for cleaning, repair, or replacement without affecting other header components.
3Productivity
If traditional down corn attachments are used, then downed crop material is gathered effectively, but the overall weight of the header increases
Solution Approach 1:
The system uses ground reaction force through drive wheels to power the gathering chains, eliminating the need for heavy powered drive mechanisms, motors, or complex transmission systems that would increase header weight.
Solution Approach 2:
The attachment uses lightweight individual chain and wheel assemblies per row unit rather than a single heavy mechanical system, reducing overall weight while maintaining gathering effectiveness across multiple rows.
