Crusher Bucket Jaw Gap Adjustment With Internal Removable Spacers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crusher buckets face limitations in adjusting the discharge size of crushed material due to the need for bulky and heavy spacers, which are difficult to transport and manage, leading to productivity issues and potential loss of adjustment capabilities.
Innovation Solution
A crusher bucket with an adjustment device that includes a strut between the movable and fixed jaws, allowing for adjustable distance control through removable spacers stored within the bucket, ensuring easy access and reducing the need for external spacer packs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional crusher buckets with flat or slightly curved surfaces are used, then manufacturing is simple and cost is low, but material wear is excessive and service life is short
Solution Approach 1:
The patent applies spheroidality by forming the bucket surface with a pronounced curved configuration rather than flat or slightly curved surfaces. This curved surface geometry distributes wear more evenly across the bucket during operation, significantly reducing material wear and extending service life while maintaining manufacturability through standard forming processes
2Productivity
If crusher buckets operate continuously without interruption, then productivity is maximized, but maintenance requirements increase and operational reliability decreases
Solution Approach 1:
The patent implements preliminary action through the curved surface design that prevents material buildup and reduces wear from the outset. By addressing wear prevention proactively through the curved geometry rather than reacting to wear problems, the bucket maintains reliable performance throughout continuous operation, reducing the need for interruptions and maintenance

AI summary
A crusher bucket (1) comprises a frame (2), crushing elements (10, 11) comprising a movable jaw (10) and a fixed jaw (11) which are received in the frame (2), and an adjustment device which can change a distance between the jaws (10, 11) at an outlet (8) of the material. The adjustment device comprises a strut having a first end and a second end which are opposite each other and which are received in a first seat which is defined in the frame (2) and in a second seat which is defined in the movable jaw (10), respectively, and one or more spacers which are or can be removably inserted between the first seat and the first end of the strut through a first opening which is constructed in a side wall (3) of the frame.
