Soil Mixing Conveyor Layout for Accurate Ratio Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soil reclamation devices lack user-friendliness in terms of usability and efficiency in mixing construction-generated soil with other base materials and additives.
Innovation Solution
A mixing device featuring a carrying conveyor that conveys base materials and additives in a specific direction, with a rotating member that mixes them, and a positioning method using imaging to align devices for precise supply and mixing, ensuring accurate mixing ratios and improved wear resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rotation axis of the rotating member intersects with the conveyance center line of the carrying conveyor, then the mixing action is more direct, but the wear on the rotating member and conveyor increases significantly
Solution Approach 1:
The patent applies asymmetry by deliberately offsetting the rotation axis of the rotating member from the conveyance center line of the carrying conveyor. This asymmetric arrangement creates a mixing action that is effective while reducing direct contact and wear between components. The offset distance is specifically designed to balance mixing efficiency with component protection.
2Adaptability or versatility
If a gate mechanism is used to control the supply ratio of base materials, then the mixing ratio can be adjusted, but the operation complexity and difficulty of precise control increase
Solution Approach 1:
The patent replaces the mechanical gate control system with a positioning mechanism that uses imaging technology (such as cameras or sensors) to detect and control the supply ratios. This substitution of mechanical control with optical/electronic positioning simplifies operation while maintaining precise mixing ratio control.
3Productivity
If the rotating member is positioned to optimize mixing, then mixing efficiency improves, but the wear on the carrying conveyor and rotating member increases
Solution Approach 1:
The patent employs asymmetric positioning where the rotation axis is deliberately offset from the conveyance center line. This creates an optimal mixing action through the offset rotation while simultaneously reducing wear by preventing direct intersection between the rotating member and conveyor, thus improving both mixing efficiency and component durability.

AI summary
A positioning method for positioning a first device and a second device separated from the first device is described. The second device is moved so as to approach the first device, a first mark on the first device and a second mark on the second device are imaged, and information is output based on the imaging the first mark and the second mark.
