Plow Vibrator Assembly for Soil Friction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plowing methods are energy-intensive and result in poor soil preparation due to high fuel consumption and the formation of macro clods, with existing vibrators either jamming on obstacles or failing to adjust vibration force according to soil conditions.
Innovation Solution
A plow equipped with a vibrator assembly, force sensor, and controller that adjusts vibration frequency and intensity based on soil conditions, reducing friction and energy consumption by optimizing the position and power of the vibrator relative to the share and moldboard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a traditional plow is used for plowing, then the plow can perform basic soil cutting and turning, but the fuel consumption is very high and macro clods are left on the soil surface
Solution Approach 1:
The patent applies mechanical vibration to the plow's working tools (share, moldboard, chisel) to reduce soil adhesion and friction. The vibration system generates oscillatory movements that prevent soil from sticking to the plow surfaces, thereby reducing the energy required for plowing and eliminating macro clods while improving soil preparation quality
Solution Approach 2:
The patent implements periodic vibration action at specific frequencies (500-1200 vibrations per minute) to continuously break up soil clods and prevent macro clod formation. The periodic oscillatory movement ensures consistent soil particle separation and maintains effective plowing throughout the operation
2Adaptability or versatility
If a vibrator with connecting rod-crank system is used, then vibrations are transmitted to the plow blade, but the travel is fixed and cannot be adjusted during ploughing
Solution Approach 1:
The patent transitions from a fixed travel vibration system to a dynamic adjustable system where the vibration amplitude and frequency can be modified during operation. This allows the plow to adapt to different soil conditions and obstacle types, improving versatility without requiring complete structural redesign
Solution Approach 2:
The patent enables change in vibration parameters (amplitude, frequency) during plowing operations. The system can adjust these parameters based on soil conditions, obstacle detection, and operational requirements, providing adaptability while maintaining a relatively simple overall structure
3Loss of energy
If a vibrator is applied to the plow to reduce energy consumption, then fuel costs decrease, but the device complexity increases
Solution Approach 1:
The patent integrates a vibration system directly into the plow's existing structure, using the plow's own components (share, moldboard, chisel) as vibration transmission elements. This approach reduces energy consumption through vibration-induced soil loosening while minimizing additional structural complexity by utilizing existing parts
Solution Approach 2:
The patent combines the vibration function with the existing plow structure rather than adding a completely separate vibration mechanism. The vibration system is merged with the working tools and support structure, reducing overall device complexity while achieving energy savings
