Ruijinfeng 4HW-2 Peanut Digger: Innovative Technology for Efficient Harvesting

The Ruijinfeng 4HW-2 Peanut Digger represents a strategic leap in peanut mechanization. Designed by Qingdao Ruijinfeng to address the persistent "pain points" of traditional harvesting—such as high loss rates, plastic film interference, and inefficient soil separation—this machine combines rugged durability with innovative vibration-control technology.

1. Advanced Vibrating Screen System: The Core Innovation

Unlike traditional harvesters that rely on high-impact mechanisms, the 4HW-2 features a re-engineered harmonic vibrating screen.

• Reduced Mechanical Stress: By optimizing the vibration frequency, the machine minimizes chassis fatigue, ensuring a significantly longer service life and smoother operation.

• Precision Soil Filtration: The bottom screen is calibrated to separate soil particles accurately while keeping the peanut pods intact. This reduces "fruit drop" (loss) even in dense or heavy soil conditions.

2. Specialized Multi-Stage Cleaning Mechanism

To ensure a "cleaner-than-ever" harvest, the 4HW-2 utilizes a three-tier separation process:

1. Flat Shovel Digging: Penetrates the soil at a precise angle to lift the entire peanut root system without damaging the pods.

2. Slat Conveyor Chain: Transports the crop while providing the first stage of soil shedding.

3. Triple-Action Cleaning (Screen + Toothed Roller + Guide Bars): This combination aggressively breaks down soil clods and removes debris, leaving the peanuts neatly laid out in windrows for easy sun-drying and subsequent collection.

3. Solving the "Film Entanglement" Crisis

For regions using plastic mulch (film) for moisture retention, entanglement is a major cause of downtime.

• Protective Shielding Technology: The 4HW-2 is equipped with integrated anti-wrap protective plates. These plates act as a physical barrier, preventing mulch film from winding around the rotating shafts and conveyor components, ensuring continuous operation in complex field environments.

4. High Adaptability for Diverse Terrains

The 4HW-2 is built for versatility, allowing operators to fine-tune the machine based on real-time field data:

• Adjustable Digging Depth (80–220mm): Whether the peanuts are deep-rooted in sandy soil or shallow in harder clay, the depth control ensures maximum recovery.

• Stable Windrowing: The rear guide bars ensure that the peanuts are placed in a uniform, airy strip, which accelerates the natural drying process and reduces the risk of mold.
