Solution Overview
Problem
Existing collecting devices for drum wagons face challenges in reliably sucking up liquid manure and efficiently adjusting to varying accumulation heights and viscosities, while also requiring space-saving storage solutions.
Innovation Solution
A collecting device with a height-adjustable suction inlet relative to a tapering sliding plate, connected to a barrel via an interface, featuring a height adjustment device that automatically adjusts based on negative pressure and liquid manure level, allowing optimal suction performance and efficient collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the suction inlet is fixed in position, then the device structure is simple, but the collection efficiency varies with different accumulation heights and viscosities
Solution Approach 1:
The suction inlet is made height-adjustable relative to the sliding plate through a height adjustment device, allowing it to dynamically adapt to different liquid manure accumulation heights and viscosities during operation, thereby maintaining optimal collection efficiency without requiring a completely complex reconfigurable structure
Solution Approach 2:
The height position of the suction inlet is changed as a variable parameter to optimize suction performance under different working conditions (different accumulation heights and viscosities), while the adjustment mechanism itself is designed to be relatively simple to minimize the increase in device complexity
2Productivity
If the suction inlet is height-adjustable, then collection efficiency is optimized, but the device complexity increases
Solution Approach 1:
The height adjustment device is designed to automatically adjust the suction inlet height based on working conditions (such as accumulation height and viscosity), reducing the need for complex manual control systems and operators, thereby optimizing collection efficiency while keeping the control system relatively simple
3Volume of moving object
If the collecting device is compact for storage, then space efficiency is improved, but accessibility for operation may be reduced
Solution Approach 1:
The collecting device incorporates height-adjustable components that can be positioned optimally during operation for easy access and optimal performance, then repositioned or compacted for space-efficient storage and transport, balancing accessibility and storage requirements through dynamic reconfiguration
