Reversible Plough Wheel Locking for Stable Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reversible plows with combined wheels face issues such as improper engagement of the locking mechanism, leading to damage during turning and loss of control over working depth, especially when the wheel is not properly engaged in different configurations.
Innovation Solution
A combined wheel device with a pivot joint and tilting axis, equipped with locking surfaces and antagonistic control means, ensures stable locking and control of the wheel's position through elastic and actuator mechanisms, allowing reliable switching between working and transport configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the locking device relies solely on plow mass to engage the combined wheel, then the structure remains simple, but the locking mechanism can get stuck in unsuitable positions during turning and cause damage
Solution Approach 1:
A control means is introduced as an intermediary between the plow mass and the locking mechanism. This control means actively manages the engagement and disengagement of the locking device, preventing it from getting stuck during turning operations while maintaining structural simplicity.
Solution Approach 2:
The locking mechanism is transformed from a static mass-dependent system to a dynamic system with active control. The control means allows the locking device to adapt its engagement state based on operational conditions, enabling reliable locking during plowing and safe disengagement during turning.
2Ease of operation
If the locking device is not properly engaged in transport position, then the wheel can rotate freely around the pivot axis, but the plow loses stability and control over working depth
Solution Approach 1:
The control means provides feedback-based management of the locking mechanism. It monitors the plow's operational state and actively controls the locking device to maintain appropriate engagement levels, ensuring stability during plowing while allowing controlled freedom during transport operations.

Function Achieved in This Case
The solution provides stable, durable, and easy-to-engage locking of the combined wheel, preventing damage and maintaining control over working depth, even on uneven terrain, enhancing the plow's operational reliability and safety.
Implementation Method 1
locking surfaces, preferably flat, whose mutual contact blocks the rotation of the support arm around said tilting axis
Implementation Method 2
two mutually antagonistic means for controlling this contact, at least one of which is a controllable actuator
