Solution Overview

Problem

Existing bar belt conveyors face challenges in achieving an endless connection that is both strong and easily assemble/disassemble, as prior methods require complex processes like vulcanization, making them difficult to assemble and disassemble.

Innovation Solution

The implementation of auxiliary belt sections that bridge the belt ends, allowing tensile forces to be routed past the joint, enabling the belt ends to remain loose and easily connected via a single pitch overlap or metal belt lock, while maintaining strength and ease of assembly/disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If the belts are overlapped at their joints and vulcanized endlessly, then the service life is extended, but the ease of assembly and disassembly deteriorates

Engineering Contradiction:
Improveservice lifeVSAvoidease of assembly and disassembly
Core Design Contradiction:
Duration of action of stationary objectVSEase of operation

Solution Approach 1:

The belt system is segmented into main belts and auxiliary belt sections. The auxiliary belt sections are positioned at the joints and bear the tensile forces, while the main belts can be easily connected or disconnected. This segmentation allows the belts to be divided into functional zones: load-bearing areas (auxiliary sections) and non-load-bearing areas (main belts), enabling easy assembly/disassembly of the main belts while maintaining structural integrity through the auxiliary sections.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the belts are made endless using locking mechanisms, then the ease of assembly and disassembly is improved, but the strength of the connection deteriorates

Engineering Contradiction:
Improveease of assembly and disassemblyVSAvoidstrength of connection
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

Auxiliary belt sections act as intermediary elements at the belt joints. These auxiliary sections specifically bear the tensile forces that would otherwise have to be transmitted through the belt joint connection. By introducing this intermediary load-bearing element, the main belts can use simple locking mechanisms for connection while the overall system maintains high strength through the auxiliary sections.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If the load and tensile forces are borne solely by the endless belts, then the structural simplicity is maintained, but the ease of assembly and disassembly deteriorates

Engineering Contradiction:
Improvestructural simplicityVSAvoidease of assembly and disassembly
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

Different parts of the belt system have different functional qualities. The main belts are designed for easy connection and disassembly with simple locking mechanisms, while the auxiliary belt sections at the joints are specifically designed to bear tensile forces. This local differentiation of quality allows each component to be optimized for its specific function, achieving both ease of assembly and structural strength.

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to a bar conveyor belt for bar conveyors of agricultural machinery, with bars (5) arranged transversely to the direction of travel and parallel to one another, wherein the bars (5) have flattened and perforated fastening areas (5.1) with which they rest on tensile-strength, elastic belts (2) circulating parallel to one another and are connected to the belts (2) by rivets or similar fasteners that penetrate the fastening area (5.1) and the belts (2), the two ends (9) of which form a butt joint (8). The object of the invention is to provide a bar conveyor belt of this type which has an endless connection with high strength and is simultaneously easy to disassemble and assemble.This problem is solved according to the invention by arranging an auxiliary belt section (7) laterally adjacent to each of the belts (2), which bridges the joint (8) between the belt ends (9), wherein the belts (2) and the auxiliary belt sections (7) are blocked together by means of the rods (5).
