Multi-Plane Disk Assembly for Camber Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tillage implements lack the ability to adjust the camber angle of blades, which affects backpressure during soil engagement, limiting optimal tilling performance.
Innovation Solution
A disk assembly with a hanger spindle and blade spindle configuration that allows for simultaneous adjustment of the angle-of-engagement and camber angle of blades across multiple planes, using a pivot linkage to rotate the hanger spindle and adjust blade orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the angle-of-engagement of blades is adjusted, then the blade orientation can be optimized for soil engagement, but the camber angle cannot be adjusted which limits optimal performance and increases backpressure
Solution Approach 1:
The patent introduces adjustment in multiple dimensions by enabling camber angle adjustment in addition to the existing angle-of-engagement adjustment. The blade assembly can now be oriented in both horizontal and vertical planes, transforming a single-degree-of-freedom adjustment system into a two-degree-of-freedom system, thereby achieving optimal blade orientation from multiple angular perspectives to minimize backpressure
Solution Approach 2:
The patent makes the blade orientation dynamic by introducing adjustable camber angle capability. The blade assembly transitions from a fixed camber configuration to an adjustable one, allowing the camber angle to be varied independently of the angle-of-engagement. This dynamic adjustment capability enables optimization of blade performance under different operating conditions and soil types
2Adaptability or versatility
If multiple adjustment mechanisms are added to adjust both angle-of-engagement and camber angle, then blade orientation control is improved, but device complexity increases
Solution Approach 1:
The patent merges the angle-of-engagement adjustment and camber angle adjustment into a single integrated blade assembly structure. Both adjustment capabilities are combined in one assembly that can be adjusted as a unified unit, reducing the need for separate adjustment mechanisms and thereby limiting the increase in device complexity while still achieving multi-plane orientation control

AI summary
A disk assembly for agricultural implements comprises a disk hanger including a proximal end and a distal end opposite the proximal end. The disk assembly further includes a hanger spindle supported relative to the distal end of the disk hanger for rotation about a first axis of rotation, and a blade spindle supported relative to the hanger spindle, with the blade spindle being rotatable about a second axis of rotation oriented non-parallel relative to the first axis of rotation. Additionally, the disk assembly includes a blade coupled to the blade spindle for rotation therewith about the second axis of rotation. Moreover, the disk assembly is configured such that rotation of the hanger spindle relative to the disk hanger about the first axis of rotation results in an adjustment of both an angle-of-engagement and a camber angle of the blade.
