Split Auger Assembly with Adjustable Mounting Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing combine harvester systems face challenges with counterproductive movement of augers relative to the frame, particularly due to the length of the augers and included components, which affects the efficient movement and processing of cut crop material.
Innovation Solution
The proposed solution involves a split top auger assembly with a first and second auger positioned above the draper belts, sharing a common longitudinal axis, and a mounting bracket that prevents folding and allows for adjustable height and rotational positioning, along with retractable fingers on the second auger to minimize counterproductive movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the auger length is increased to cover greater lateral distance, then the auger can reach more areas, but counterproductive movement increases relative to the frame
Solution Approach 1:
The single long auger is divided into multiple auger sections (first auger section, second auger section, third auger section) that can be independently positioned and adjusted. This segmentation allows each section to be optimized for its specific location while reducing the counterproductive movement issues that would occur with a single long auger spanning the entire lateral distance.
2Adaptability or versatility
If additional components are included in the auger assembly to manipulate crop, then crop handling capability is improved, but device complexity and counterproductive movement increase
Solution Approach 1:
The auger assembly is segmented into multiple independently adjustable sections, each capable of being positioned at different heights and angles. This allows the system to handle various crop types and conditions without requiring a single complex monolithic structure, thereby improving versatility while managing complexity through modular design.
Solution Approach 2:
The auger sections are designed with adjustable mounting brackets that allow dynamic repositioning of each section relative to the frame. This dynamic adjustability enables the system to adapt to different crop manipulation needs while maintaining simpler individual component designs, as each section can be optimized independently rather than requiring a fixed complex structure.

AI summary
A harvesting assembly for harvesting a crop includes a frame, a cutting knife configured to cut crop, a feed drum, a draper assembly, a first auger assembly, and a second auger assembly. The draper assembly and the auger assemblies are configured to move the cut crop toward the feed drum. The auger assemblies each include a first auger, a second auger, and a mounting unit coupled to the frame and coupled between the first auger and the second auger to support the first auger and the second auger during rotation of the augers.
