Pig Feeder Synchronism Bar for Uniform Feed Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pig feeders require complex and time-consuming adjustments to achieve accurate feed dosing, particularly in trapezoid-shaped hoppers, where independent adjustment of both ends of the blocking gate is necessary, making it difficult to maintain a smooth descent and uniform aperture.
Innovation Solution
A pig feeder with a synchronism bar connected to a rotation actuating means featuring eccentric pivot means, allowing synchronized upward and downward movement of the gate, enabling easy and accurate adjustment of the feed dosing through a single manually-operated switch, ensuring a uniform opening along the discharge outlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If independent adjustment of both ends of the blocking gate is used, then the gate can be positioned, but the adjustment process becomes complex and time-consuming
Solution Approach 1:
The patent combines the adjustment of both ends of the blocking gate into a single synchronized operation. The synchronism bar links the two adjustment mechanisms (first and second adjusting screws) so that turning one screw automatically adjusts both ends of the gate simultaneously, maintaining parallelism while simplifying the operator's task to a single adjustment action rather than coordinating two independent adjustments
Solution Approach 2:
The synchronism bar acts as an intermediary mechanism between the two adjusting screws. It transmits and coordinates the adjustment motion from one screw to the other, ensuring both ends of the gate move together in a synchronized manner. This mediator component resolves the complexity by providing a mechanical link that automatically maintains the relationship between the two adjustment points
2Measurement precision
If double adjustment on both ends of the gate is implemented, then positioning is achieved, but operator skill and time requirements increase
Solution Approach 1:
The synchronism bar is pre-configured with the correct geometric relationships and linkages to automatically maintain parallelism of the gate during adjustment. This preliminary setup of the mechanical system eliminates the need for the operator to perform sequential adjustments and waiting periods, as the synchronized mechanism performs the coordinated adjustment in a single continuous action, reducing both time and skill requirements while maintaining precision
3Adaptability or versatility
If the gate is supported independently from both ends, then adjustment flexibility is provided, but maintaining horizontality becomes difficult
Solution Approach 1:
The patent introduces asymmetry in the adjustment mechanism by providing a synchronism bar that creates a dependent relationship between the two ends. While the gate itself remains symmetric in function, the adjustment system becomes asymmetric with one adjusting screw serving as the primary control and the other end being mechanically coupled through the synchronism bar, ensuring parallelism is maintained automatically during adjustment

AI summary
A pig feeder of the type comprising an inverted trapezoid-shaped hopper in which the supply of feed-to-be-dosed is loaded, which is easy to adjust by means of a single control unit that acts at the same time on both edges of the lower tray, which serves as an adjusting feed dosing gate, for which purpose a synchronism bar is provided in the upper part, which further enables an accurate readout of the dosing aperture position of the feeder by means of a rotating pointer.
