Angle Adjustable Coulter Wheel Assembly for Tillage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coulter wheel assemblies for tillage apparatuses lack versatility in adjusting their angle of entry into the soil, limiting their effectiveness across different soil types and conditions.
Innovation Solution
An angle adjustable coulter wheel assembly featuring a rotatable shank with a coulter wheel mounted on it, allowing the wheel's face to rotate about three orthogonal axes, enabling adjustable orientation in both horizontal and vertical planes, controlled by an actuator for enhanced tilling versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If coulter wheels are mounted in a fixed position, then the结构简单性 (structural simplicity) is maintained, but the adaptability to different soil types and conditions deteriorates
Solution Approach 1:
The coulter wheel assembly is transformed from a fixed static structure to a dynamic adjustable structure. The wheel can be positioned at multiple angular orientations relative to the direction of travel, allowing adaptation to different soil types and tillage requirements. This is achieved through a mounting mechanism that enables angular adjustment while maintaining structural integrity.
Solution Approach 2:
The coulter wheel assembly is divided into separable components including the wheel itself, the shank, and the mounting mechanism. This segmentation allows the wheel to be independently positioned and angled relative to the frame, providing versatility without requiring complete redesign of the entire tillage apparatus.
2Adaptability or versatility
If angle adjustment mechanism is added to coulter wheel, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The adjustment mechanism transforms the rigid fixed-position coulter wheel into a dynamically adjustable assembly. The wheel can be positioned at multiple angular orientations relative to the direction of travel, allowing adaptation to different soil types and tillage requirements. This is achieved through a mounting mechanism that enables angular adjustment while maintaining structural integrity.
Solution Approach 2:
The adjustment mechanism adds angular positioning capability as a new degree of freedom. Instead of only linear movement, the coulter wheel can now be oriented at different angles, creating a two-dimensional adjustment space (position and orientation) that significantly enhances tilling versatility.

AI summary
An angle adjustable coulter wheel assembly includes a rotatable shank having a longitudinal axis defined by an upper portion of the shank. The longitudinal axis is oriented neither vertically or horizontally with respect to the ground when the assembly is mounted on a tillage apparatus. A coulter wheel rotatably mounted on the shank proximate a lower portion of the shank. An actuator rotates the upper portion of the shank about the longitudinal axis to cause the face of the coulter wheel to rotate about three orthogonal axes thereby changing orientation of the face of the coulter wheel with respect to the ground when the assembly is on the tillage apparatus. The coulter wheel assembly permits adjusting the angle of the coulter wheel in at least two planes permitting greater control over how much soil the coulter wheel disturbs during tilling.
