Removable Gap Tines for Harvester Reel Assembly Crop Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing reel assemblies in harvester headers are inefficient due to gaps between tines, which allow cut crops and other materials to pass through, reducing their effectiveness in moving and lifting crops.
Innovation Solution
The introduction of gap-filling tines that are removably coupled to the carrier bar, designed to contact standard tines and prevent rotation, ensuring effective engagement with cut crops without penetrating the carrier bar, thus enhancing the reel assembly's efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gap-filling tines are added to the reel assembly, then the effectiveness in moving and lifting crops is improved, but the device complexity increases
Solution Approach 1:
The reel assembly is segmented into standard tines and removable gap tines, allowing the gap tines to be added only where needed to fill spaces between standard tines. This segmentation enables targeted improvement of crop-moving effectiveness without uniformly increasing complexity across the entire assembly.
Solution Approach 2:
The gap tines are designed to be removably coupled to the carrier bar, allowing dynamic adjustment of the reel assembly configuration. Operators can add or remove gap tines based on crop conditions and operational requirements, maintaining flexibility while improving productivity when needed.
2Adaptability or versatility
If gap-filling tines are removably coupled to the carrier bar, then the adaptability of the reel assembly is improved, but the ease of operation deteriorates
Solution Approach 1:
The gap tines are designed with self-retaining features that allow them to be easily attached to and removed from the carrier bar without requiring additional tools or complex procedures. The removable coupling mechanism enables operators to quickly adjust the configuration by simply adding or removing tines hand-over-hand.
3Reliability
If gap-filling tines contact standard tines to prevent rotation, then the reliability of crop engagement is improved, but the device complexity increases
Solution Approach 1:
The gap tines are positioned and configured to work in conjunction with the existing standard tines, merging their functions to create a continuous engaging surface. The gap tines contact the standard tines to prevent rotation, combining the structural support of standard tines with the gap-filling function of added tines to improve crop engagement reliability.

AI summary
A reel assembly for a harvester head of an agricultural machine includes a carrier bar, standard tines coupled to the carrier bar, and gap tines removably coupled to the carrier bar and such that the gap tines do not penetrate an outer surface of the carrier bar. The gap tines contact the standard tines to prevent rotation of the gap tines relative to the carrier bar during operation of the work machine.
