Articulating Conveyor Frame for Permit-Free Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reload conveyors for spreading bulk materials like compost and grass seeds are limited by their rigid frames, which make them too long and wide for efficient transportation on public thoroughfares, requiring special permits and escorts due to their dimensions exceeding standard truck bed widths.
Innovation Solution
An articulating conveyor frame design that allows the reload conveyor to pivot and adjust its length and width, transforming from a long, wide material transfer configuration to a shorter, narrower transport configuration, enabling safe and permit-free travel on public highways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid conveyor frame is used to ensure structural stability and material transfer capacity, then the conveyor can handle a wide range of materials effectively, but the overall length and width exceed public thoroughfare limitations requiring special permits and escorts
Solution Approach 1:
The conveyor frame transitions from a rigid static structure to a dynamic articulating structure that can change its configuration. The frame includes multiple sections that can pivot relative to each other, allowing it to extend to a first length for material transfer operations and retract to a second, shorter length for transportation, thereby resolving the contradiction between needing length for operational reliability and needing compactness for transport compliance
Solution Approach 2:
The conveyor frame is divided into multiple separable sections or segments that can be articulated or telescoped. This segmentation allows the frame to be extended when material transfer capacity is needed and contracted when transportation dimensions must be reduced, enabling the system to adapt its length based on operational requirements while maintaining structural stability during both states
2Productivity
If the hopper is sized to exceed the width of standard truck beds for effective material reception, then material transfer efficiency is improved, but the width exceeds public thoroughfare limitations requiring wide load permits
Solution Approach 1:
The hopper width is made dynamic rather than fixed. The hopper can be extended to a first width that exceeds standard truck bed dimensions during material transfer operations to ensure effective reception and loading efficiency. During transportation, the hopper retracts or folds to a second, narrower width that complies with public thoroughfare limitations, thereby resolving the contradiction between operational productivity and transport compliance
Solution Approach 2:
The hopper structure incorporates nested or collapsible sides that can be extended outward during material transfer to increase capacity and width for efficient loading from wide truck beds. During transport, these sides are retracted or folded inward, allowing the hopper to fit within standard width limitations without requiring special permits, thus maintaining both operational effectiveness and legal compliance

AI summary
A reload conveyor with an articulating conveyor frame is provided. The reload conveyor includes a main conveyor frame and a placement conveyor frame positioned at a discharge end of the main conveyor frame. The placement conveyor frames articulates to assume a transport configuration and a material transfer configuration. The overall length of the placement conveyor frame in the transport configuration is substantially shorter than in the material transfer configuration. A pair of material receiving mechanisms are provided and arranged to assume a material transfer configuration and a transport configuration.
