Screen Bucket Vibration Isolation for Earth-Mover Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen buckets for soil material sorting are inefficient and cause significant vibration in earth-moving machines, leading to reduced operational comfort and increased wear on machine structures.
Innovation Solution
A screen bucket design where only the transverse bars are vibrated, using a vibrator unit and transmission member to transmit vibration, allowing for efficient sorting with reduced vibration transmission to the machine, and featuring adjustable gap sizes and independent vibration phases for improved sorting capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the entire bucket is made to vibrate for sorting material, then sorting efficiency is improved, but vibration is transmitted to the work machine causing operational discomfort and increased wear
Solution Approach 1:
The invention segments the vibration function by introducing separate transmission members that connect only specific bars to the vibrator, rather than vibrating the entire bucket. This allows localized vibration of individual bars or groups of bars, achieving sorting efficiency while isolating the vibration from the machine structure.
Solution Approach 2:
The transmission members act as intermediaries between the vibrator and the bars. These members selectively transmit vibration to specific bars while preventing vibration transmission to the bucket body and machine structure, thus resolving the contradiction between sorting efficiency and vibration isolation.
2Productivity
If conventional screen buckets vibrate the entire bucket structure, then material sorting is achieved, but energy consumption and wear increase
Solution Approach 1:
The vibration energy is segmented and applied only to the specific bars that contact the material, rather than the entire bucket structure. The transmission members enable selective energy delivery to individual bars or bar groups, reducing overall energy consumption while maintaining sorting effectiveness.
Solution Approach 2:
The invention applies vibration locally to specific bars where it is most needed for material sorting. The transmission members are positioned to deliver vibrational energy precisely to the bars that interact with the material, avoiding unnecessary energy expenditure on non-essential bucket portions.
3Strength
If bars are rigidly fixed to the bucket bottom, then structural strength is improved, but sorting efficiency decreases due to lack of bar movement
Solution Approach 1:
The invention transitions from a static, rigid bar fixation to a dynamic system where bars can move relative to the bucket bottom. The transmission members connect bars to the vibrator in a way that allows bars to oscillate and adapt their position during operation, enhancing sorting efficiency while maintaining structural integrity through the vibration-driven motion.
