AI Technical Summary

Technical Problem

Existing peanut harvesters suffer from problems such as complex layout, complex material flow path, easy blockage, high center of gravity, and difficult maintenance, and are particularly unsuitable for harvesting fresh peanuts.

Method used

The single-layer layout design includes a seedling cutting and crushing mechanism, a digging mechanism, a soil removal and conveying mechanism, a fruit removal mechanism, a screening mechanism, and a fruit box. The material flow path is simplified. The material is rationally diverted through a transverse conveying auger, a side conveying mechanism, and an air suction mechanism to avoid multiple lifting operations. The transmission box is used for centralized drive to achieve efficient power distribution.

Benefits of technology

It achieves rational material flow, low failure rate, convenient maintenance, low center of gravity with no risk of tipping over, adapts to fresh fruit harvesting, and improves harvesting efficiency and equipment reliability.
