Date: March 25, 2025 | Source: China National Intellectual Property Administration (CNIPA)
Patent Overview
Jinan Rubber Roller Factory, a leading agricultural machinery manufacturer with over three decades of expertise, has officially obtained Patent No. CN 231753413 U for its innovative “Impact-Resistant Polyurethane Huller Rubber Roller“. This groundbreaking design addresses critical challenges in rice hulling equipment durability and performance, marking a significant advancement in agricultural machinery technology.
Why This Patent Matters
1. Solving a Decade-Old Problem
Traditional rice huller rubber rollers are prone to deformation during transportation and high-impact hulling operations. This limits equipment lifespan and increases maintenance costs for mill operators. Our patent introduces a multi-layer stress-distribution system that mitigates these risks.
2. Technical Breakthrough
The patented design integrates three core components:
- Reinforced Polyurethane Layer: Made from high-abrasion NBR/PU blends, this layer resists wear from grain friction.
- Patented Stress-Bearing Blocks: Strategically placed to absorb shock during collisions.
- Dual-Channel Grooves: Divert impact energy away from critical areas through optimized pressure dispersion.
Key Features & Advantages
| Feature | Benefit | Technical Specification |
|---|---|---|
| Impact Absorption | Reduces deformation by 60% in drop tests | 3-point load-bearing structure |
| Extended Lifespan | 20% longer service life vs. competitors | 85–95 Shore A hardness rating |
| Low-Temperature Resilience | Operates effectively at -20°C | Cold-resistant polyurethane blend |
| Easy Maintenance | Modular design for quick replacement | Snap-fit assembly system |
Real-World Applications
1. Rice Milling Operations
- Prevents roller collapse during peak harvest seasons.
- Maintains consistent grain quality by minimizing pressure fluctuations.
2. Export Markets
