Vibratory Ripper Mechanism for Hard Material Trenching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plowing, trenching, and ripping machines face difficulties when attempting to form trenches through hard materials like rock and concrete, as previous methods using vibration have been insufficiently effective.
Innovation Solution
A ripping mechanism for vehicles, comprising a support frame, a ripping member, and a vibrator mechanism that reciprocates the ripping member forwardly and rearwardly, allowing for adjustable angle of attack and enhanced engagement with the ground through a pivotally supported engagement head, which is connected to a hydraulic system for movement and powered by a motor with eccentric weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vibration is used to assist plowing, trenching, or ripping machines, then the machine's ability to handle hard materials is improved, but the effectiveness is insufficient for rock, concrete, and similar materials
Solution Approach 1:
The patent applies mechanical vibration through a vibrator mechanism that generates reciprocating motion of the ripping member. The vibration is transmitted through the ripping member to create impact forces when engaging hard materials, significantly improving the ability to break rock, concrete, and other challenging materials compared to conventional non-vibrating rippers
Solution Approach 2:
The ripping member undergoes periodic reciprocating motion, moving forward into the material to engage and break it, then retracting rearwardly. This periodic action allows the ripping member to repeatedly impact hard materials, accumulating breaking effect over multiple cycles and significantly enhancing productivity in breaking rock and concrete
2Adaptability or versatility
If the ripping member is made pivotally supported to allow angle adjustment, then the adaptability to different materials and conditions is improved, but the device complexity increases
Solution Approach 1:
The ripping member is pivotally supported on the support frame, allowing it to rotate about a pivot axis. This dynamic configuration enables the angle of attack to be adjusted by rotating the ripping member to different angular positions, providing adaptability to various material conditions and operational requirements while maintaining a relatively simple pivotal connection mechanism

AI summary
In an aspect, the invention is directed to a ripping mechanism for a vehicle. The ripping mechanism includes a support frame, a ripping member and an impact mechanism which is configured to reciprocate the ripping member forwardly and rearwardly. The impact mechanism is preferably a vibrator mechanism. In a particular embodiment, the ripping mechanism has a longitudinal axis, is mountable to the vehicle and is movable between a raised position and a lowered position. The ripping member has an engagement head that is configured for plowing a groove in the ground and that is pivotally supported on the support frame about a ripping member pivot axis that is positioned such that pivoting of the ripping member displaces the engagement head longitudinally. The impact mechanism is preferably a vibrator mechanism. The vibrator mechanism is connected to the ripping member wherein activation of the vibrator mechanism causes reciprocating pivoting movement of the ripping member.
