Minimal Tuber Damage

1.Excavation 

Features double-row vibrating digging shovels with hydraulic depth control. With a digging depth range of 0–200 mm and adjustable vibration frequency, it minimizes collisions between tubers and shovels, reducing damage at the source.

2.Conveying

Adopts 21° gentle-inclination steel conveying chains with buffer idlers. Rubber/foam buffer transition devices are installed throughout the process to avoid hard contact between tubers and metal components, lowering conveying damage.

3.Cleaning

Combines the two-stage soil screening chain with a low-wind centrifugal fan. The mild vibration and adjustable air volume effectively remove light impurities (weeds, broken vines) without damaging tubers.

4.Harvest Metrics

Tuber damage rate ≤ 1.5%, missed harvest rate ≤ 0.5%. The impurity content of cleaned tubers meets industry standards, making it suitable for both seed and commercial potato harvesting, and effectively reducing harvest losses.

High Harvest Efficiency

1.Cleaning System

The composite configuration of two-stage soil screening chains and a centrifugal fan (air volume: 226 m³/min / 8,000 CFM) enables flexible air volume adjustment for efficient soil impurity separation.

2.Anti-Clogging Design

The first-stage chain removes bulk soil, while the second-stage screens fine soil. Combined with a counter-rotating cleaning table, it completely solves clogging issues in sticky-wet fields and plastic mulch planting scenarios.

3.Operational Efficiency

When paired with side-discharge potato harvesters, it adopts a 2-row + 2-row coordinated operation mode, harvesting 4 rows at a time. With an ideal efficiency of 400 tons per hourand 24/7 continuous operation capability, it eliminates manual picking, significantly improving efficiency and reducing labor costs.

Excellent Durability

1.Frame

Integrally welded with high-strength carbon steel, with key parts reinforced and thickened. It offers superior torsion and bending resistance, resists deformation, and has a service life of 8–10 years.

2.Transmission System

Utilizes a distributed hydraulic transmission layout combined with gearbox drive, featuring a compact, efficient structure and low failure rate.

3.Core Components

Conveying chains, digging shovels and screens are made of wear-resistant manganese steel or high manganese steel, processed by heat treatment. They exhibit excellent wear and corrosion resistance, reducing the replacement frequency of vulnerable parts.

4.Transport Adaptability

The 3.05 m narrow-body design allows for legal transportation without disassembly, adapting to farm roads. The optimized overall dimensions balance operational efficiency and transport convenience, making it suitable for plains, hills and other terrains.
