Baler Binding Material Storage Frame Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural big bale balers face challenges with weight, user comfort, and efficient storage of binding material, as existing solutions are heavy and complex, leading to difficulties in managing binding material rolls and ensuring uninterrupted operation.
Innovation Solution
The design incorporates a lightweight, dust-proof support frame with tubular structures and pivotable machine paneling elements made from plastic or composite materials, allowing for easy maintenance and intuitive binding material management, including adjustable storage columns and a sensor system for tracking consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal shelves or trays are used to store binding material rolls, then the storage structure can support the weight of the rolls, but the overall weight of the baler increases significantly
Solution Approach 1:
The patent employs composite materials, specifically plastic or composite panels, to replace traditional metal shelves and trays for storing binding material rolls. These composite storage elements maintain sufficient load-bearing capacity to support rolls weighing 5-15 kg each, while dramatically reducing the overall weight of the baler compared to all-metal construction. The composite materials provide an optimal balance between strength and weight reduction.
2Ease of operation
If complex storage box designs with multiple shelves and trays are used, then binding material can be organized and stored, but the device complexity and weight increase
Solution Approach 1:
The storage system is segmented into multiple independent support frames positioned along the pressing channel, each capable of holding binding material rolls. This modular segmentation allows for intuitive organization of binding material by type or usage sequence, while keeping each individual storage unit relatively simple in structure. The segmented approach avoids the need for a single complex multi-level storage box.
Solution Approach 2:
The support frames are designed to be movable or adjustable rather than fixed, allowing operators to reposition them along the pressing channel as binding material is consumed. This dynamic capability enhances ease of operation and material management without requiring complex fixed storage structures with multiple shelves and trays.
3Stability of the object's composition
If binding material rolls are stored in fixed positions, then the storage structure is stable, but maintenance access and operational flexibility are reduced
Solution Approach 1:
The support frames are designed with movable elements that allow them to be shifted or repositioned along the pressing channel. This dynamic design maintains stability during operation when frames are positioned, but enables easy access for maintenance and refilling of binding material rolls. The frames can be moved out of the way or opened for servicing without compromising the overall structural stability of the baler.
4Reliability
If more binding units are used to handle binding material, then uninterrupted operation is ensured, but the weight and complexity of the machine increase
Solution Approach 1:
Multiple support frames are pre-loaded with binding material rolls before operation begins. This preliminary preparation ensures that binding material is readily available for all binding units throughout the pressing channel, enabling continuous uninterrupted operation. By pre-positioning multiple rolls in accessible locations, the system avoids the need for frequent stops to replace binding material, thereby ensuring reliability without requiring an excessive number of binding units or complex automated replenishment systems.
