Plough Mouldboard Vibration Damper Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plow bodies with mouldboards face wear and rattling issues due to screw connections, which compromise the integrity and stability of the mouldboard attachment to the plow supporting body, especially at higher speeds.
Innovation Solution
Incorporating vibration dampers, such as spring elements or elastic intermediate layers, between the mouldboard and the plow supporting body to ensure a secure, rattle-free attachment without allowing free relative movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw connections are used to attach the mouldboard to the plow supporting body, then the attachment is secure and stable, but wear occurs at the bonding area and rattling happens at higher speeds
Solution Approach 1:
The patent introduces a vibration damper as an intermediary component between the mouldboard and the plow supporting body. This damper absorbs vibrations and prevents rattling while maintaining secure attachment, eliminating the need for screw connections that cause wear and noise at higher operating speeds.
Solution Approach 2:
The patent replaces the mechanical screw connection system with a vibration damper-based attachment system. This substitution eliminates the harmful mechanical interactions that cause wear and rattling, while maintaining the necessary attachment stability through the damper's vibration-absorbing properties.
2Strength
If the mouldboard is made particularly hard in the bonding area to reduce wear, then wear resistance improves, but the attachment still allows free relative movement and rattling
Solution Approach 1:
The vibration damper serves as a mediator that provides both wear resistance through its material properties and attachment stability through its vibration-dampening capability. It eliminates the need to make the mouldboard harder in the bonding area while still achieving wear resistance and preventing rattling.
3Reliability
If vibration dampers are introduced to eliminate rattling, then attachment stability improves, but assembly complexity increases
Solution Approach 1:
The patent modifies the attachment system by changing the physical parameters of the connection - introducing a vibration damper with specific damping characteristics. This parameter change achieves rattle-free operation while the damper's design allows for relatively simple assembly, balancing improved reliability with acceptable assembly complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides a low-wear, rattle-free mounting of mouldboards, applicable to both full and individual mouldboard strips, maintaining stability even at higher plow speeds and stress levels.
Implementation Method 1
fastening means have vibration dampers and that the mouldboard is fixed to the plow supporting body with these vibration dampers interposed
Implementation Method 2
simple spring elements can be used as vibration dampers

AI summary
The body (1) has a moldboard (2) provided in form of a solid body metal sheet or a stripe body (2.1). An attachment element is glued on the moldboard and mounted on a plow support body (7). The attachment element comprises a vibration damper such that the moldboard is fixed at the plow support body under interposition of the vibration damper. The vibration damper is designed as a spring element and as an intermediate layer part from a resilient material. The attachment element comprises a connection piece formed as a screw nut connection.
