Hay Bale Feeder with Counter-Rotating Shredder Drums
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large square hay bales are difficult to break apart and distribute efficiently, as existing mechanized solutions are either ineffective, expensive, or require additional machinery, making it challenging for ranchers to feed livestock during winter months when grass is scarce.
Innovation Solution
A hay bale feeder system that can be attached to a three-point hitch tractor, featuring counter-rotating shredder drum assemblies and hydraulic actuation, allowing for easy loading, shredding, and distribution of hay bales, utilizing gravity and adjustable angles to control the shredding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual breaking with pitch fork is used, then cost is reduced, but labor requirement increases and efficiency decreases
Solution Approach 1:
The system uses the tractor's own hydraulic system and three-point hitch mechanism to automatically lift, position, and shred the hay bale without requiring separate manual operations or additional machinery. The tractor performs all functions through integrated mechanical advantage and hydraulic actuation.
Solution Approach 2:
The invention combines multiple functions (lifting, positioning, shredding, and distributing) into a single integrated attachment that operates through one hydraulic system. The counter-rotating drum assembly merges the shredding function with the feeding mechanism, eliminating the need for separate lifting and breaking operations.
2Productivity
If existing mechanized solutions are used, then productivity increases, but cost increases making them prohibitive
Solution Approach 1:
The invention uses simple, inexpensive materials such as counter-rotating drums with protrusions, hydraulic cylinders, and standard three-point hitch components. These elements are designed to be cost-effective and easily replaceable, avoiding the need for expensive specialized machinery while maintaining high productivity.
Solution Approach 2:
The attachment is designed to be universally compatible with standard tractor three-point hitches and hydraulic systems. The same mechanism can handle different bale sizes and types, and the system can be attached to or detached from existing tractors without requiring custom-built equipment, thereby reducing overall system cost.
3Ease of operation
If additional machinery is required for lifting and placing, then capability is improved, but device complexity increases
Solution Approach 1:
The lifting and positioning functions are merged with the shredding operation. The hydraulic cylinder simultaneously performs the function of lifting the bale onto the drum assembly and positioning it for shredding, eliminating the need for separate lifting machinery and reducing overall system complexity.
Solution Approach 2:
The counter-rotating drum assembly acts as an intermediary mechanism that receives the bale from the tractor's three-point hitch, processes it through shredding, and feeds it to the distribution mechanism. This intermediary function integrates multiple operations into a single continuous action, reducing the need for additional separate machinery.
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 system effectively breaks down large square hay bales into manageable pieces, allowing for efficient distribution and feeding of livestock, reducing the need for manual labor and additional machinery while being cost-effective.
Implementation Method 1
counter-rotating shredder drum assemblies... break apart the bale
Implementation Method 2
shredder drum assemblies can be provided at a front of the feeder for shredding a portion of the hay bale in direct contact with studs that radially protrude from the drums
Implementation Method 3
A hydraulic linear actuator can extend between the tractor and a top of the frame. By retracting and extending the actuator, the frame can be moved and/or rotated upwardly and downwardly about the pivoted connection to the tractor
Implementation Method 4
the bale can be slid onto the support arms by driving the tractor towards the bale... the frame and the associated support arms can be rotated upwardly causing the bale to slide towards the shredder drums
Data Source
AI summary
A hay bale feeder is described. Embodiments of the hay bale feeder include a frame, one or more bale support members, and a pair of spaced apart drum assemblies. The hay bale feeder can be implemented to shred a square hay bale. The hay bale feeder can typically be attached to a tractor or other vehicle. The pair of spaced apart drum assemblies can include a pair of drums having protrusions that are adapted to shred a square hay bale as the square hay bale is gravity fed to the pair of drum assemblies.
