Pelletized Feed Distributor Auger and Gravity Door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanical feed distributors for pelletized livestock feed are impractical for large operations, as they require manual distribution or complex mechanisms that are inefficient and prone to feed loss or trampling, especially in dry weather.
Innovation Solution
A pelletized feed distributor featuring a hopper with an auger system and a selectively opening discharge door mechanism, utilizing a door linkage assembly that cyclically opens and closes the discharge door through a rotational path, and an optional cam system for gravity-assisted operation, along with a chute extension and manual door kicker for efficient feed distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If hand distribution is used for pelletized feed, then feed loss is minimized, but labor efficiency deteriorates for large operations
Solution Approach 1:
The mechanical feed distributor is designed to operate autonomously without requiring manual distribution. The auger system automatically conveys feed from the hopper to the discharge point, and the gravity-assisted discharge mechanism opens and closes the door cyclically to distribute feed evenly. This self-service mechanism eliminates the need for manual labor while maintaining controlled distribution that prevents feed loss and trampling.
2Productivity
If complex mechanical mechanisms are used for automated distribution, then productivity improves, but device complexity increases
Solution Approach 1:
The patent replaces complex motorized or automated door actuation mechanisms with a simple gravity-assisted system. The cam mechanism works in conjunction with the weight of the discharge door itself to achieve cyclic opening and closing. When the cam rotates to the appropriate position, it releases the door, allowing gravity to pull it open for feed discharge. The door then naturally closes under its own weight or a simple spring return mechanism, eliminating the need for complex powered actuators, sensors, or control systems.
3Ease of operation
If gravity-assisted door operation is used, then ease of operation improves, but control precision deteriorates
Solution Approach 1:
The discharge door system uses a dynamic cam mechanism that rotates in synchronization with the auger. The cam profile is specifically designed to control the timing and duration of door opening. As the cam rotates, it progressively raises and lowers the door at controlled rates, ensuring smooth opening and closing actions. This dynamic control, combined with the gravitational force, achieves precise discharge timing and duration without requiring complex positioning systems or powered actuators.
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
The solution enables efficient and controlled distribution of pelletized feed, minimizing waste and ensuring consistent feeding, whether in continuous rows or discrete lots, across large areas without the need for extensive manual labor or complex machinery.
Implementation Method 1
a hopper having an auger positioned at the bottom thereof for moving feed in the hopper toward a discharge opening
Implementation Method 2
A cam is mounted on and end of the auger over the door and a cam follower is connected to the end of a lift arm pivotally connected to a hopper end wall above the door with the cam follower resting on an upper portion of the periphery of the cam... As the smaller diameter section of the cam rotates under the cam follower, gravity pulls the door, the connecting rod and lift arm downward to close the opening formed in the hopper.

AI summary
A pelletized feed distributor includes a hopper having an auger positioned at the bottom thereof for moving feed in the hopper toward a discharge opening. A discharge door selectively closes the discharge opening. A door linkage connected between the auger and the discharge door cyclically opens and closes the door.
