Segmented Rigid Wheel Rim for Irrigation Traction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-propelled irrigation systems face issues with traction and mud accumulation, leading to deep tire tracks and difficulty in navigating uneven or wet fields, which can cause the system to get stuck.
Innovation Solution
A wheel apparatus with a rim assembly comprising spaced, cylindrical rigid members that contact the ground, supported by a center portion and a structural frame, allowing mud and debris to pass through and enhancing traction while minimizing mud ejection from the wheel track.

1Force
If conventional pneumatic tires with lug tread are used on drive wheel assemblies, then adequate traction is provided, but deep tire tracks form in wet and muddy conditions
Solution Approach 1:
The wheel is segmented into multiple rigid members (typically 3-5) spaced apart around the rim, replacing the continuous pneumatic tire structure. This segmentation allows mud and debris to pass through the spaces between members, preventing deep track formation while maintaining traction through the distributed contact points of each rigid member.
Solution Approach 2:
The wheel structure incorporates porous characteristics by having spaces between the rigid members, allowing the passage of mud and debris. This porous design enables the wheel to traverse wet and muddy fields without displacing large amounts of material, thereby minimizing deep tire track formation while preserving adequate ground contact for traction.

AI summary
A wheel apparatus for a self-propelled irrigation system has a center portion, a rim assembly, and a support structure disposed between the center portion and the rim assembly. The rim assembly has a plurality of rigid members spaced apart from each other with longitudinal axes that are parallel with each other and equidistant from the axis of rotation. The rigid members are cylindrical with unsupported ends, and a mounting portion between the ends is connected to an outer periphery of the support structure. The rigid members are held in a fixed position relative to the center portion by the support structure. The rigid members are arranged to contact the ground surface to support the irrigation system with spaces between the rigid members allowing mud and debris to pass freely between the rigid members during operation to enhance traction while minimizing mud from being forced out of a wheel track.
