An onion harvester is a specialized agricultural machine designed for the mechanized harvesting of onions. Its primary functions include efficient digging, separation, and transportation of onions. It is suitable for various soil types and significantly improves operational efficiency while reducing labor requirements.

Core Functions

· Efficient Digging: Utilizes a rotating mechanism and conveyor belts to lift onions from the soil. For example, the German Deutz-Fahr 6215 tractor paired with a McConnel onion harvester can achieve a harvesting rate of over 45 mu per hour.
· Soil Adaptability: Suitable for heavy clay, medium clay, and sandy loam soils with a moisture content below 25%. The digging shovel is designed to minimize soil accumulation and weed entanglement.
· Separation and Transportation: The lifting components feature an alternating arrangement of curved and straight rods and an elliptical gear structure, enhancing separation efficiency. When combined with a transport vehicle, it can harvest 50 mu in half a day.

Advantages

· Reduced Damage Rate: The belt-type lifting chain design minimizes damage to the onions. After operation, the soil is finely broken, reducing subsequent tillage costs.
· Mechanized Coordination: Typically used in conjunction with tractors or transport vehicles, forming a complete harvesting process.
