Fodder Bucket Rotor Design for Fibrous Material Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buckets used for distributing fodder, such as corn and silage grass, face difficulties in emptying due to fibrous materials sticking together, leading to irregular flow rates and obstruction of the drain opening, even with disentangling members, as material clumps form on oblique walls and vertical closures.
Innovation Solution
A bucket design featuring a disentangling member with a rotor positioned close to the drain opening, where the rotor's free end is spaced minimally from the oblique or back wall to allow material to slide freely, and decompaction means like cylindrical portions with helicoids to prevent clustering, ensuring continuous and regular emptying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a disentangling member with rotor is installed close to the drain opening to decompact material, then the emptying flow is improved, but material clumps form on the oblique wall and vertical closing wall, obstructing the opening
Solution Approach 1:
The invention extracts the problematic oblique wall and vertical closing wall elements that cause material clumping, removing them from the bucket structure. By eliminating these surfaces where material tends to aggregate, the solution addresses the clumping issue while preserving the beneficial disentangling rotor function near the drain opening.
Solution Approach 2:
The invention changes the spatial arrangement by removing the oblique wall configuration and replacing it with a different structural dimensioning that prevents material from contacting surfaces where clumping occurs. This dimensional reconfiguration allows material to flow more freely toward the drain opening without forming obstructive clumps on wall surfaces.
2Reliability
If the rotor is positioned close to the front wall to defragment material, then decompaction is improved, but material sticks together on the oblique wall forming a deflector
Solution Approach 1:
The invention removes the oblique wall that acts as a deflector surface where material aggregates. By extracting this problematic structural element, the solution eliminates the location where material sticking together occurs, while the rotor continues to perform its decompaction function effectively in the modified space.
Solution Approach 2:
Instead of positioning the rotor to work against the oblique wall configuration (which causes clumping), the invention inverts the approach by removing the oblique wall entirely. This reverses the problem-solution dynamic, allowing the rotor to operate in open space without creating the harmful deflector effect on wall surfaces.
3Productivity
If material is conveyed toward the drain opening by the transfer member, then emptying is facilitated, but fibrous material sticks together and forms heaps obstructing the opening
Solution Approach 1:
The invention extracts the oblique wall and vertical closing wall structures that serve as surfaces for material aggregation. By removing these elements, the solution eliminates the locations where fibrous material forms obstructive heaps, allowing the transfer member to convey material smoothly toward the drain opening with regular flow.
Solution Approach 2:
The disentangling rotor performs preliminary decompaction action on the material before it reaches the drain opening. By pre-defragmenting the fibrous material as it is conveyed, the rotor prevents the material from sticking together and forming obstructive heaps at the critical discharge point, ensuring regular flow throughout the emptying process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

AI summary
The present invention relates to a bucket intended for loading and unloading materials, comprising a bin (B) defining a container for the material, comprising; a rear wall (Pd) supporting a means for coupling with a carrier vehicle; a front wall (Pf) tilted and rising towards the outside, in the normal position for unloading said bucket, to facilitate the loading of the bucket in a stack; a transfer means (Mt) forming an emptying member arranged in the bottom of the bin; a side opening passing through the bin (B) in order to empty the material from the bucket during the operation of said transfer means; and a separating member arranged in the bin (B) opposite said opening, said separating member comprising a rotor with the teeth on the outside and capable of being rotated in order to defragment the material carried by the transfer means (Mt) in order to project same through said opening.
