1. Classification & Core Application Scenarios

Corn rapid picking machines are primarily categorized by power source and structural design, with each type optimized for small-to-medium corn plots and scenarios demanding fast ear harvesting with minimal complexity.

2. Harvesting Performance (Core "Rapid" Feature)

Operating Efficiency:

Self-propelled model: 8–15 mu/day; working speed: 2.0–3.5 km/h (adjustable via gearbox)

Tractor-mounted model: 3–8 mu/day; working speed: 1.5–2.5 km/h (depends on tractor speed)

Ear Picking Capacity:

Self-propelled model: 800–1,500 kg/h (fresh corn ears, moisture content 25–35%)

Tractor-mounted model: 400–800 kg/h

Ear Loss Rate: ≤ 3% (shattering loss ≤ 1%, unharvested ear loss ≤ 2%) – meets agricultural machinery standards (e.g., GB/T 21922, ISO 7258)

Husking Efficiency (for husking-enabled models):

Partial husking: Removes 70–85% of outer husks (reduces manual post-processing by 60%)

Full husking (premium option): Removes 90–95% of husks (for direct market-ready corn)

3. Power System

Self-propelled Model:

Engine Type: Vertical 4-stroke air-cooled diesel engine (easy maintenance, no coolant required)

Rated Power: 15–30 HP (11.0–22.1 kW)

Fuel Type: 0# diesel (summer) / -10# diesel (winter, for low-temperature regions like Northeast China)

Fuel Consumption: 2.0–3.5 L/mu (30–40% lower than large corn combine harvesters)

Tractor-mounted Model:

Required Tractor Power: 12–25 HP (8.8–18.4 kW)

PTO Speed: 540 rpm (compatible with most small-to-medium tractors globally)

Power Transmission: Belt drive (simple structure, low maintenance cost)

4. Machine Dimensions & Weight (Core "Convenient" Feature)

Self-propelled Model:

Overall Dimensions: 3,000–3,800 mm (L) × 1,400–1,800 mm (W) × 1,700–2,100 mm (H)

Wheelbase: 1,600–2,000 mm; Minimum Turning Radius: ≤ 3.0 m (fits narrow paths between small plots)

5. Ear Picking & Collection System (Corn-specific Design)

Picking Mechanism:

Core Component: 2–4 rubberized picking rolls (diameter: 80–120 mm) – gentle on corn ears, avoids bruising

Roll Speed: 600–900 rpm (adjustable for different corn varieties: sweet corn, waxy corn, field corn)

Row Adaptation: Single-row (standard) or double-row (optional for self-propelled models); suitable row spacing: 50–70 cm (global common corn row width)

Collection Device:

Self-propelled model: 100–200 L detachable plastic/metal hopper – 1 full hopper = 0.5–1.0 mu of harvested ears (reduces unloading frequency)

Tractor-mounted model: 50–100 L hanging bag or small hopper – directly collects ears for easy manual transfer

Husking Attachment (optional):

Structure: Rotating husking plates + air blower (removes loose husks)

Power Requirement: Extra 2–5 HP (for self-propelled models) or tractor PTO extension

6. Operation & Maintenance Convenience

Tractor-mounted model: Simple manual switches (integrated with tractor controls, no additional training needed)

Wear Parts Accessibility:

Key wear parts (picking rolls, husking plates, belts) are modular – replacement time ≤ 10 minutes per part; spare parts kit included

Cleaning Design: Openable side panels (≥ 300 mm × 250 mm) – easy to remove corn silk and debris after daily use

Transport & Storage:

Self-propelled model: Equipped with 5.00–12 agricultural tires (max road speed: 12 km/h) – no need for a trailer

Tractor-mounted model: Foldable frame – reduces storage space by 35–40% when not in use

7. Adaptability to Corn & Field Conditions

Corn Variety Compatibility: Works with sweet corn (ear length 15–25 cm), waxy corn (18–28 cm), and field corn (20–30 cm)

Corn Maturity Tolerance: Suitable for milk stage (fresh eating) to dough stage (drying) – adjusts via picking roll speed

This Self-propelled Corn Rapid Picking Machine (22 HP, 12 Mu/Day, Single-Row with Partial Husking) is a high-efficiency solution tailored for small-to-medium corn farms, family growers, and village-level agricultural teams-designed to replace labor-intensive manual corn picking with fast, low-loss ear harvesting. It integrates single-row corn picking and partial husking in one compact, self-propelled unit, delivering a daily harvest capacity of 12 mu (≈0.8 hectares) and cutting picking time by 80% compared to manual work. With a lightweight design (850 kg), simple handlebar controls, and compatibility with sweet, waxy, and field corn, it adapts to narrow plots and hilly areas (slope ≤15°) common in Asia, Africa, and Latin America. Compliant with GB/T 21922, CE, and ISO 7258 standards, it balances performance and usability, making it an ideal choice for growers seeking to boost harvest efficiency without high investment in large combine harvesters.

Self-propelled Corn Rapid Picking Machine (22 HP, 12 Mu/Day, Single-Row with Partial Husking) delivers exceptional "rapid" performance with high efficiency and minimal ear loss. Powered by a 22 HP vertical 4-stroke air-cooled diesel engine, it achieves a working speed of 2.5–3.2 km/h and a picking capacity of 1,100 kg/h (fresh corn ears, moisture content 28–32%)-enough to harvest a 10-mu corn field in under a day. Its core picking system uses two rubberized picking rolls (diameter: 100 mm, speed: 750 rpm) that gently separate corn ears from stalks, avoiding bruising (critical for fresh-market corn). The integrated partial husking attachment (rotating husking plates + small air blower) removes 75–85% of outer husks, reducing manual post-processing time by 60%. The ear loss rate is kept ≤2.8% (shattering loss ≤0.9%, unharvested loss ≤1.9%), ensuring maximum yield retention for growers.

Self-propelled Corn Rapid Picking Machine (22 HP, 12 Mu/Day, Single-Row with Partial Husking) features a fuel-efficient, low-maintenance power system for cost-effective long-term use. The 22 HP diesel engine (brand: Changchai, a trusted agricultural power supplier) uses 0# diesel (summer) or -10# diesel (winter) with a fuel consumption of just 2.2 L/mu-35% lower than large corn combine harvesters, which translates to $5–$8 in daily fuel savings for 12 mu of harvest. The air-cooled design eliminates the need for radiator cleaning or coolant replacement, cutting monthly maintenance time by 4–6 hours. A 120 L fuel tank supports 6+ hours of continuous operation, avoiding frequent refueling breaks during peak harvest seasons.

Self-propelled Corn Rapid Picking Machine (22 HP, 12 Mu/Day, Single-Row with Partial Husking) boasts a compact, user-friendly structure that excels in narrow and scattered plots. Its overall dimensions (3,400 mm L × 1,500 mm W × 1,900 mm H) and 2.8 m minimum turning radius allow easy navigation through 1.2–1.5 m wide field paths and U-turns in 0.5-mu small plots-addressing the "large machine can't enter small fields" pain point for many smallholders. The handlebar-mounted control panel has only 5 core levers (engine start, speed adjustment, picking roll on/off, husking function toggle, emergency stop), so novice operators can master basic use in 15 minutes of guided training. For transport between fields, it is equipped with 5.00–12 agricultural tires (max road speed: 12 km/h), eliminating the need for a separate trailer.

Self-propelled Corn Rapid Picking Machine (22 HP, 12 Mu/Day, Single-Row with Partial Husking) offers strong adaptability to diverse corn varieties and field conditions. It works seamlessly with sweet corn (ear length 15–25 cm), waxy corn (18–28 cm), and field corn (20–30 cm)-simply adjusting the picking roll speed (600 rpm for tender sweet corn, 900 rpm for tough field corn) to match maturity. It tolerates corn moisture content of 22–35%, operating normally even for slightly wet corn after light rain. With 250 mm ground clearance, it avoids damage from field stones or stubble, while its ≤15° slope tolerance makes it suitable for hilly regions (e.g., Sichuan Basin in China, Colombian highlands). The 150 L detachable plastic hopper holds ears from 0.7–0.9 mu of corn, so growers only need to unload 13–17 times per day for 12 mu of harvest.

Self-propelled Corn Rapid Picking Machine (22 HP, 12 Mu/Day, Single-Row with Partial Husking) prioritizes operator safety and easy maintenance to ensure reliable long-term use. Safety features include an emergency stop button (response time ≤0.5 seconds) on the handlebar, protective guards for the picking rolls and husking plates (preventing accidental contact), and anti-slip footrests (critical for stability on wet/muddy fields)-meeting CE (EN 13306) and CCC safety standards. Key wear parts (rubber picking rolls, husking plates, drive belts) are modular and included in a free spare parts kit; each part can be replaced in ≤10 minutes with basic tools. A large 350 mm × 300 mm side maintenance door allows quick cleaning of corn silk and debris after daily use, preventing mold buildup. It also comes with a 1-year warranty for the engine and main components, plus 24/7 online technical support for troubleshooting.
