Conveyor Belt Scraper Displacement Guide Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing conveyor belt scraper devices require high forces to handle and remove scraper segments, especially when they are dirty, due to high connecting forces between segments and the support shaft, making the process cumbersome and labor-intensive.
Innovation Solution
The design incorporates displacement guides on the support shaft that can be isolated and coupled using a connecting device, allowing one displacement guide to be spatially removed from another without moving the coupled guides, reducing the forces needed to separate and handle individual scraper segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If scraper segments are coupled together on the support shaft, then the scraper device maintains structural integrity and torque transmission, but high forces are required to separate and handle individual segments
Solution Approach 1:
The scraper device is divided into multiple independent scraper segments that can be separated from each other. Each segment can be individually handled and removed from the support shaft without requiring high forces to separate the entire coupled assembly, thus reducing the separation force while maintaining structural integrity during operation
Solution Approach 2:
The invention allows individual scraper segments to be extracted from the coupled assembly on the support shaft. By enabling selective removal of segments, the system eliminates the need to apply high separation forces to the entire coupled structure, addressing the contradiction between maintaining structural integrity and reducing separation force
2Power
If scraper segments are coupled together, then torque transmission is improved, but the handling and removal of segments becomes labor-intensive
Solution Approach 1:
The scraper segments are designed as separable units that maintain torque transmission when coupled during operation. However, they can be easily separated and handled individually when maintenance or replacement is needed, thus improving ease of operation while preserving power transmission capability
Solution Approach 2:
The coupling between scraper segments is designed to be dynamic rather than fixed. The segments can be coupled together during operation to transmit torque effectively, and easily separated when handling is required, allowing the system to adapt between power transmission mode and maintenance mode
3Stability of the object's composition
If multiple scraper segments are coupled on the support shaft, then the scraper device maintains stability, but the forces required to pull segments off increase with the number of segments
Solution Approach 1:
The scraper device is segmented into independently removable units. This segmentation allows the system to maintain stability during operation with multiple segments coupled together, while enabling easy removal of individual segments without requiring high pulling forces to separate the entire assembly
Solution Approach 2:
Individual scraper segments can be extracted from the coupled assembly on the support shaft without requiring high pulling forces. The extraction mechanism allows selective removal of segments while maintaining the stability of the remaining coupled segments, thus resolving the contradiction between stability and pulling force

AI summary
The invention relates to a conveyor belt scraping device for a conveyor belt of a conveyor belt system, having a support shaft and at least two displacement guides which are arranged next one another on the support shaft in a positively locking manner so as to transmit torque. Each of the two displacement guides is displaceable in the longitudinal direction of the support shaft after a fastening device has been released and are connected to a holding end of a scraping segment, wherein the scraping element has a scraping end which is spaced apart from the holding end and which can be brought into contact with the conveyor belt. The two displacement guides can be actively coupled to one another in the longitudinal direction of the support shaft by means of a connecting device. The one displacement guide, in a state of coupling with the other displacement guide at a predefined spacing from the other displacement guide, is displaceable along the longitudinal direction of the support shaft and then, at the predefined spacing from the other displacement guide, is displaceable together with the other displacement guide along the longitudinal direction of the support shaft as a result of the coupling by means of the connecting device. The invention also relates to a displacement guide for mounting a scraping segment on a support shaft of a conveyor belt scraping device.
