Crusher Bucket Movable Jaw Structure for High-Load Crushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crusher buckets face challenges in withstanding the loads generated during material crushing due to wear and deformation of the movable jaw, requiring reinforcement and simplification of assembly.
Innovation Solution
A crusher bucket design featuring a movable jaw with increased rigidity through cross-members of varying sections, a combination of eccentric and strut connections, and adjustable distance between jaw portions, along with reinforcement plates and spacers for enhanced structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the movable jaw is reinforced to withstand crushing loads, then the strength and durability are improved, but the weight and number of components increase, complicating assembly and movement
Solution Approach 1:
The movable jaw features cross-members with varying sections where the second cross-member has a greater section than the first cross-member. This local variation in structural properties reinforces areas experiencing higher loads while maintaining lighter construction in less stressed regions, thus improving strength without uniformly increasing weight and complexity throughout the entire jaw structure.
2Reliability
If additional components are added to reinforce the movable jaw, then the structural integrity is improved, but the assembly complexity and number of parts increase
Solution Approach 1:
The movable jaw is constructed as an integrated framework combining longitudinal members, cross-members with varying sections, and reinforcement plates into a unified structural assembly. This merging of components into a coordinated framework achieves enhanced reliability through improved load distribution and structural integrity while reducing the number of separate parts compared to adding discrete reinforcement elements.
3Adaptability or versatility
If the distance between jaw portions is made adjustable, then the adaptability for different output sizes is improved, but the device complexity increases
Solution Approach 1:
The movable jaw is designed with a movement device that enables dynamic adjustment of the distance between the front and rear portions of the jaw. This dynamic capability allows the crusher bucket to adapt to different material sizes and desired output specifications, providing versatility without requiring multiple fixed-configuration jaws. The movable framework with adjustable spacing achieves adaptability through controlled motion rather than multiple static components.

AI summary
A crusher bucket (1) comprises a frame (2) in which there are defined a material inlet (7) and a material outlet and a material flow direction from the inlet (7) to the outle and crushing elements (10, 11) comprising a movable jaw (10) and a fixed jaw (11) which are received in the frame (2). The movable jaw (10) comprises a pair of longitudinal members which extend in the flow direction and a plurality of cross-members which are mutually parallel and which extend from one of the longitudinal members to the other.
