Silo Vehicle Distribution Tool Height Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficient distribution and compaction of harvested material in flat silos due to the need for specialized knowledge and experience, leading to increased fuel consumption and delayed treatment processes, as operators often push up already compacted material with distribution tools, resulting in higher resistance and suboptimal fermentation results.
Innovation Solution
A method utilizing a control unit to ascertain dry-substance density and maximally producible compaction pressure, adjusting the layer thickness of the distribution tool in real-time to optimize compaction, with automated adjustments to the distribution tool's position, allowing for efficient and uniform material distribution and compaction, reducing operator workload and improving fermentation outcomes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If the distribution tool is lowered too far during material distribution, then compaction pressure increases, but already compacted material is pushed up again causing increased resistance and fuel consumption
Solution Approach 1:
The distribution tool's height is made dynamically adjustable rather than fixed. The control unit continuously adjusts the height based on real-time feedback about layer thickness and compaction state, allowing the system to optimize between compaction pressure and resistance forces during operation
Solution Approach 2:
A feedback mechanism is implemented where sensors monitor the layer thickness and compaction state of the harvested material. This information is fed back to the control unit, which automatically adjusts the distribution tool height to maintain optimal compaction pressure without pushing up already compacted material
2Ease of operation
If manual distribution and compaction is performed without specialized knowledge, then operational simplicity increases, but distribution uniformity and compaction quality deteriorate
Solution Approach 1:
The system performs self-adjustment of the distribution tool height based on automatic sensing and control. The machine serves itself by autonomously optimizing its operating parameters without requiring specialized operator knowledge, thereby maintaining high distribution uniformity while simplifying operation
Solution Approach 2:
The manual mechanical adjustment of distribution tool height is replaced with an automated control system that uses sensors and actuators. This substitution eliminates the need for operator expertise while maintaining precise control over distribution uniformity and compaction quality
3Productivity
If layer thickness is not optimized, then distribution speed increases, but compaction efficiency and fermentation results deteriorate
Solution Approach 1:
The layer thickness is made dynamically optimizable through automated control. The system continuously adjusts distribution parameters based on real-time conditions to maintain optimal layer thickness for both speed and fermentation quality
Solution Approach 2:
The system optimizes the layer thickness parameter automatically based on material properties and compaction requirements. By dynamically adjusting this critical parameter, the system achieves both high distribution speed and optimal fermentation conditions

AI summary
A method for assisting a compaction-appropriate distribution of harvested material in a flat silo includes providing a silo vehicle having a control unit, ascertaining a dry-substance density to be achieved via the control unit, determining a maximally producible compaction pressure via the control unit, ascertaining a maximally permissible layer thickness via the control unit for the implementation of a distribution-and-compaction process, determining a layer thickness currently being applied during the implementation of the distribution-and-compaction process in a location-specific manner via a GPS receiver, comparing the maximally permissible layer thickness and the layer thickness currently being applied in the location-specific manner via the control unit in order to ascertain a target layer thickness, and driving a regulating device of a distribution tool provided on the silo vehicle to assimilate the layer thickness currently being applied to the target layer thickness via the control unit in an automated manner.
