Hay Rake Tooth Mounting Clip With Widened Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting clips for hay rake teeth are inadequate in raking power, especially in short or heavy crops, as they allow excessive crop material to be left behind or jumped over due to insufficient strength and spacing.
Innovation Solution
A modified mounting clip with an elongated channel and laterally widened sections to increase surface area for elastomeric blocks, allowing for more teeth without compromising turning strength, featuring extended flanges for alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional mounting clips are used with standard length, then turning strength is sufficient, but raking power is inadequate and crop collection efficiency is low
Solution Approach 1:
The mounting clip is divided into distinct functional sections: a central portion for mounting to the wheel rim and laterally widened sections for receiving elastomeric blocks. This segmentation allows optimization of each section's function - the central portion maintains turning strength while the widened sections increase tooth capacity and raking power.
Solution Approach 2:
The mounting clip transitions from a simple linear structure to a three-dimensional configuration with laterally widened sections. This dimensional change increases the surface area for elastomeric block attachment, allowing more teeth to be mounted around the wheel rim, thereby increasing raking power and crop collection efficiency.
2Power
If more teeth are mounted around the wheel rim, then raking power increases, but turning strength may be reduced
Solution Approach 1:
Different portions of the mounting clip have different structural qualities - the central portion is designed for mounting strength while the laterally widened sections are designed for tooth attachment. This local differentiation allows the clip to simultaneously provide turning strength and accommodate more teeth for increased raking power.
Solution Approach 2:
The mounting clip combines different material properties in different sections - the central portion provides structural strength for mounting while the widened sections provide surface area for elastomeric block attachment. This composite approach allows optimization of both turning strength and tooth capacity.
3Productivity
If conventional clip design is used, then manufacturing is simple, but crop material passes between teeth and is left in the field
Solution Approach 1:
The mounting clip is segmented into a central portion and laterally widened sections, allowing independent optimization of each function. The widened sections provide greater surface area for elastomeric blocks, reducing crop material passage while maintaining manufacturability through standard forming processes.

AI summary
A mounting clip includes an elongated channel having a first end, a central portion, and an elongated second section. Along the elongated section are at least two laterally widened sections that provide greater surface area for receiving an elastomeric block of a tooth. At least one of the ends of the channel extend beyond one of the laterally widened sections.
