Retaining Guard for Coil Tine Scattering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural equipment with coil tines faces issues where broken tine pieces scatter and can damage equipment, pose health hazards, and contaminate crops, due to the lack of effective retaining mechanisms.
Innovation Solution
A retaining guard is designed for coil tines, featuring an elongated main portion with a securing channel and a retaining flap angled relative to the main axis. This configuration prevents broken tine pieces from moving past the flap, ensuring they remain attached to the equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coil tines are mounted to rotating components using a main bolt, then the coil tines can be securely attached, but broken tine pieces may scatter and fall into crops or equipment when the coil tine breaks off
Solution Approach 1:
The retaining guard is divided into multiple functional segments: an elongated main portion that extends through the coil section, a retaining flap that projects toward the rotating component, and a securing channel that receives the attachment member. This segmentation allows each part to perform its specific function in preventing broken pieces from scattering.
Solution Approach 2:
The retaining guard acts as an intermediary component between the coil tine and the rotating component. It mediates the potential harmful effect of broken tine pieces by intercepting them and preventing them from scattering into crops or equipment, while still allowing the coil tine to perform its raking function.
2Device complexity
If no retaining guard is used, then the device complexity is low, but broken coil tine pieces can damage agricultural equipment and pose health hazards
Solution Approach 1:
The retaining guard applies local quality by providing protection only where needed - at the attachment area and along the coil section where broken pieces are most likely to scatter. The elongated main portion is positioned specifically to intercept broken pieces, while the retaining flap provides additional protection at the proximal end, without unnecessarily complicating the entire coil tine assembly.
3Reliability
If the retaining flap is positioned to prevent coil section movement, then broken pieces are retained, but the coil tine movement may be restricted
Solution Approach 1:
The retaining flap is designed with dynamic characteristics - it is angled relative to the main axis and positioned to provide protection only when needed. The flap can deflect or move out of the way during normal coil tine operation, allowing free movement, but positions itself to intercept and retain broken pieces when they attempt to scatter.

AI summary
A retaining guard for a coil tine is provided. The retaining guard includes an elongated main portion having a securing channel adapted to receive an attachment member to mount the retaining guard to the rotating component of an agricultural equipment. The elongated main portion extends axially through the coil section along a first axis. The retaining guard also includes a retaining flap positioned at a first end of the elongated main portion adjacent to a prong of the coil tine and projecting towards the rotating component when the retaining guard is mounted thereon. The retaining flap is angled relative to the first axis and is sized and shaped to define a barrier preventing the coil section of the coil tine to move past the retaining flap along the first axis, in the occurrence of a break of a section of the coil tine.
