Core functions and working principles of potato harvester

The main function of a potato harvester is to dig out potatoes buried underground and automatically separate soil and stems and leaves, reducing damage during the harvesting process.

1. Homework process: The machine excavates and excavates the potato chunks together with the soil, and then shakes them with a lifting chain or vibrating screen to allow fine soil to leak down. The potato chunks are then transported to the ground or collection box.

2. Separation technology: Mainstream models use vibration screening or rod type lifting chain technology to separate soil and potato chunks based on their physical differences. Some high-end models introduce air flow cleaning or intelligent monitoring systems.

3. Core advantage: Mechanized harvesting can significantly reduce labor costs. For example, in the observation activity at Jieshou in Anhui, a harvester can harvest nearly 4 acres of greenhouse potatoes per hour, with efficiency far exceeding that of manual labor. ‌‌

🚜  Main classification and selection suggestions

According to the terrain, planting scale, and operational requirements, potato harvesters can be divided into various types, and the selection should be based on actual working conditions.

Classified by homework completeness:

1. Excavation type: Only completes excavation, requires manual picking, simple structure, suitable for small plots.

2. Excavation separation type: Complete excavation and soil potato separation, lay potato blocks on the ground, and require manual picking or subsequent collection.

3. Joint harvester: capable of completing excavation, separation, collection, and packing in one go, suitable for large-scale planting, with the highest efficiency. ‌‌

Classified by power and structure:

1. Traction/suspension type: It needs to be used with a tractor, such as the HiSen Tiancheng 4UL-170C (two row traction type), suitable for plain areas.

2. Self propelled: With its own power and flexible operation, it is suitable for hilly and mountainous areas, such as the circular mountain ladder and field track self-propelled type. ‌‌

Selection suggestion:

1. Plain areas: Priority should be given to large combine harvesters or tractor type multi row machines, with a daily operating volume of up to hundreds of acres.

2. Hilly and mountainous areas: It is recommended to choose small and medium-sized hand-held equipment or tracked self-propelled models to adapt to complex terr. ‌‌
