Wing Positioning Apparatus for Farm Implement Berming Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The combination of tracked and wheeled supports in farm implements causes soil berming and damage, especially at field edges during turns, due to mismatched rotational axes leading to dragging of the wheeled supports.
Innovation Solution
A pivot arm system that allows the wheeled support to be positioned relative to the tracked support, adjusting its rotational axis alignment to minimize dragging during turns, with operational, turn, and elevated positions to manage wing height and clearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wheeled supports are positioned proximate the wing frame to avoid interfering with folding, then wing folding is enabled, but soil berming occurs during turning due to dragging of the wheeled supports
Solution Approach 1:
The patent applies the dynamics principle by making the wheeled support position adjustable through a pivot arm mechanism. The wheeled support can be dynamically repositioned between a first position proximate the wing frame for folding and a second position forward of the tracked support for operation. This dynamic repositioning allows the system to adapt its configuration based on whether it is in transport mode or operation mode, eliminating soil berming during turning while maintaining folding capability.
Solution Approach 2:
The patent segments the support system into distinct components: tracked supports for weight distribution, wheeled supports for wing support, and a pivot arm mechanism for positioning. By segmenting the system, each component can be independently positioned and optimized for its specific function. The wheeled support is separated from the wing frame by the pivot arm, allowing independent positioning to prevent soil contact during turning while maintaining structural support during operation.
2Weight of moving object
If tracked support rotational axis is positioned forward of wings, then weight distribution is improved, but wheeled support rotational axis must be positioned rearward causing dragging during turns
Solution Approach 1:
The patent makes the wheeled support position dynamic by using a pivot arm that can rotate the wheeled support between different positions. During operation, the wheeled support is positioned forward of the tracked support rotational axis to align rotational axes and prevent dragging. During folding, it returns to its original position proximate the wing frame. This dynamic adjustment resolves the contradiction between weight distribution optimization and soil disruption prevention.
Solution Approach 2:
The pivot arm acts as an intermediary mechanism between the wing frame and the wheeled support. It mediates the position of the wheeled support, allowing it to be forwarded during operation to align with the tracked support rotational axis, thereby preventing soil disruption. The pivot arm serves as the mediating structure that enables the wheeled support to occupy positions that would otherwise be structurally problematic.
3Object-affected harmful factors
If wheeled support is positioned forward to align rotational axes, then soil berming is reduced, but wing clearance for folding is reduced
Solution Approach 1:
The patent uses dynamic repositioning of the wheeled support via the pivot arm to resolve this contradiction. During operation, the wheeled support is positioned forward to align rotational axes and reduce soil berming. During folding, the pivot arm rotates to return the wheeled support to its original position, restoring adequate wing clearance. The dynamic nature of the system allows it to optimize for different operational states without permanent compromise to either parameter.

AI summary
A farm implement supported by at least one wheeled support mounted on a pivot arm extending from a wing and at least one tracked support on a main carrier. The tracked support can be rotated about a primary rotational axis and the wheeled support being rotatable about a secondary rotational axis. The pivot arm can be rotated to position the wheeled support to elevate or lower the wing. The rotational of the pivot arm also changes the alignment of the secondary rotational axis of the winged support relative to the primary rotational axis of the tracked support to prevent berming when maneuvering the farm implement.
