Corn sheller 5TY-1250C

Overview
The maize sheller is a front-shovel, self-suction machine for on-site threshing. Available in self-propelled and towed versions with multi-axis threshing drums (3, 5 or 6 axes).

Working principle
The U-shaped front shovel gathers ears from the ground; an internal auger feeds material to the conveyor. Conveyor belt and scraper carry ears to the threshing drum where high-speed rotation and elements (e.g., swinging hammers) remove kernels. Sieves separate cobs and kernels and fans remove dust and light impurities to complete threshing.

Structural features

• Hydraulic front shovel; widened shovel options for higher feeding efficiency.
• Transmission channels, conveyor belts, scraper and augers for material handling.
• Multi-axis threshing drums (3/5/6 axes) and optional fully enclosed operator cab.
• Telescopic suction drums and 360° hydraulic high-level unloading for easy discharge.

Performance advantages

• Automatic feeding reduces manual labor and supports continuous operation.
• High throughput: examples range from ~10–30 acre/h up to 60–100 acre/h depending on model; some models can process ~20,000 kg/h.
• Effective threshing with high kernel removal rate and low impurity content.
• Good mobility for flexible use at road edges, yards and varied sites.

Power configuration
TYPICAL power options start around 22 hp; medium/large self-propelled models commonly use 90–130 hp diesel engines (e.g., 120 hp or 130 hp for certain variants).

Self-suction model (example)
The self-suction 5-axis self-propelled Model 2025 is offered with 120 hp or 130 hp engines, two feeding modes (air suction and spiral front shovel), fully enclosed cab, telescopic suction drum, 360° hydraulic rotating unloading and enlarged cob hopper; capacity around 20,000 kg/h.

Technical advantages

• Efficient multi-axis threshing: some six-drum configurations feed two drums simultaneously for fast kernel removal.
• Thorough cleaning: whistle-type double centrifugal suction or large fans remove dust and fuzz; some models collect dust to reduce emissions.
• Multiple feeding methods: dual-mode air suction and front shovel suitable for road and storage threshing.
• User-friendly controls: many self-propelled units offer enclosed cabs and optional intelligent one-click control.

Design features
Industrial-grade construction, available as self-propelled or towed, customizable to regional requirements.

Process overview

• (1) Feeding: spiral front shovel or air-suction device lifts ears and feeds via chain or auger; suction uses negative pressure for different stacking conditions.
• (2) Threshing: ears enter a multi-axis drum where wear-resistant elements interact with concaves at high speed to remove kernels; cobs are discharged separately.
• (3) Selection & separation: screening boxes and vibration separate intact kernels, broken kernels and impurities; fans perform wind selection to remove leaves and light impurities.
• (4) Unloading: clean kernels are transported to the grain bin by augers or telescopic drums and discharged to transport vehicles via a hydraulically controlled high-level 360° rotating unloading device.
