Feed Mixer Discharge Slide Flush Transition Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixing containers for feed mixer wagons experience increased power requirements and material flow disturbances due to lateral steps at the discharge opening, leading to wear and inefficiency during the mixing process.
Innovation Solution
The discharge opening's edge region is offset outward, allowing for a flush, stepless transition between the slide and container wall, reducing resistance and wear, and utilizing guide profiles and wear-resistant materials to facilitate smooth movement and minimize residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the slide overlaps the edge regions of the container wall laterally delimiting the discharge opening, then the slide can be guided displaceably on the container wall, but lateral steps are created that disturb material flow and increase resistance during mixing
Solution Approach 1:
The edge region is offset in the radial dimension to create a stepped structure, allowing the slide to move linearly in one dimension while maintaining flush transition in another dimension, eliminating the harmful steps that disturb material flow
Solution Approach 2:
The container wall is given different qualities in different regions: the edge region has increased radial offset to accommodate the slide mechanism, while the adjoining section maintains the original geometry to ensure smooth material flow, creating local optimization without compromising overall performance
2Ease of operation
If the slide overlaps the edge regions of the container wall, then the slide can be guided displaceably, but wear in the transition area between slide and container wall increases
Solution Approach 1:
By offsetting the edge region radially, the invention creates a stepped structure that allows the slide to be guided externally while maintaining internal flush transition, separating the guidance function from the material flow path to reduce wear in critical areas
Solution Approach 2:
The slide guidance function is extracted from the internal material flow path and placed in an external position, allowing the slide to be guided on the outer surface of the container wall while the internal surface remains smooth and flush, reducing wear between the slide and container wall
3Use of energy by moving object
If the edge region is offset outward to enable flush transition, then resistance and wear are reduced, but the container wall structure becomes more complex
Solution Approach 1:
The container wall is segmented into distinct functional zones: the edge region with radial offset for slide accommodation, and the adjoining section with original geometry for smooth material flow, allowing each segment to optimize its specific function without compromising the whole

AI summary
The mixing container (11) comprises a container wall with a discharge opening, which is laterally bordered with lateral edge regions of the container wall. A slider (3) is attached with the container wall and guided between locking position and open position of the discharge opening. A rotating mixing tool is provided for mixing the feed. The discharge opening laterally determines boundaries of edge region of the container wall.
