Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vibrators used in screen buckets for soil material sorting are inefficient and operationally flawed, particularly in handling materials of varying particle sizes, as they are heavily influenced by the mass of the material being screened.
Innovation Solution
A novel vibrator system utilizing a rotating element with a mating surface, where the outer surface of the vibrator is eccentrically positioned relative to the rotating axle, generating vibrating motion through physical contact with the mating surface, which is designed to be durable, efficient, and adaptable for diverse screening needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional eccentric-type vibrators are used, then vibration motion can be generated, but the screening efficiency is reduced and the operation is heavily influenced by material mass
Solution Approach 1:
The vibrator is divided into separate functional components: a rotation device with rotating axle, a vibrator element with eccentric outer surface, and a separate mating surface. This segmentation allows the vibration generation mechanism to be independent from the material being screened, reducing the influence of material mass on operation.
Solution Approach 2:
A mating surface is introduced as an intermediary between the vibrator element and the screen surface. The vibrator element with eccentric outer surface contacts the mating surface to generate vibration, which is then transmitted to the screen. This intermediary allows controlled vibration generation that is not directly dependent on material mass.
2Reliability
If conventional vibrators are used, then vibration can be produced, but the structure becomes complex and reliability decreases
Solution Approach 1:
By segmenting the vibrator into distinct components (rotation device, vibrator element, mating surface), each component can be designed and manufactured independently with simpler structures, improving overall reliability while reducing complexity.
Solution Approach 2:
Instead of using a traditional eccentric weight rotating to generate vibration, the invention inverts the approach by using an eccentric outer surface on a rotating element that contacts a separate mating surface. This inversion simplifies the structure by eliminating the need for heavy eccentric weights while maintaining vibration generation capability.
3Productivity
If standard vibrators are used, then screening can be performed, but the screening rate is reduced and operational stress on equipment increases
Solution Approach 1:
The invention utilizes mechanical vibration generated by the rotating vibrator element with eccentric outer surface contacting the mating surface. This controlled mechanical vibration improves screening rate by enhancing material movement through the screen while reducing operational stress through smooth, controlled vibratory motion rather than harsh shaking.
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
The solution enhances screening efficiency by minimizing the impact of material mass on vibration intensity, allowing for improved sorting of difficult materials with reduced operational stress on equipment, and is simpler, more reliable, and cost-effective compared to traditional eccentric-type vibrators.
Implementation Method 1
The outer surface of the vibrator element comprises surfaces at distances from the rotating axle, which are directed towards the mating surface of the vibrator. When a vibrator element of this type is rotated around the rotating axle, the rotating outer surface of the vibrator element causes motion on the mating surface arranged against it.

AI summary
The invention relates to a vibrator, bucket, and vibration method. The vibrator (16) comprises a rotation device (18) which is arranged to rotate (P) a rotating axle (19) and at least one vibrator element (17) arranged on it. The vibrator element comprises an outer surface that has different distances (R) from the rotating axle. The outer surface of the vibrator element is in contact with a mating surface (20). When the vibrator element is rotated, vibrating motion V is generated.
