Technical Field
The invention relates to a cyperus esculentus separating and cleaning device and a cyperus esculentus harvester formed by the same, in particular to a multistage vertical conical tube cyperus esculentus separating and cleaning device and a cyperus esculentus harvester formed by the same.
Background
The cyperus esculentus is a crop with high quality, high yield and high comprehensive utilization value, the origin is Africa and the coastal countries of the Mediterranean region, belongs to gramineae annual plants, and is a high-quality, high-yield and comprehensive utilization economic crop which is introduced from Africa in the first few years of China department of agricultural scientific research and integrates grain, oil, pasture and feed into a whole. The cyperus esculentus is similar to peanuts, and is mainly used for harvesting underground nuclear rhizome fruits, because the root systems of the cyperus esculentus grow well, the labor intensity is high during manual harvesting, the processing is complex, and most of the cyperus esculentus is harvested by selecting a cyperus esculentus excavator to work, so that the efficiency during harvesting is improved, but the fruit processing is not thorough, the yield is low, the screening effect is not ideal, and the processing efficiency is low.
Researchers have also researched and developed some cyperus esculentus harvesting or separating machines in recent years, but the harvesting machine has the main problem that the harvesting machine cannot completely separate all cyperus esculentus from plants, namely, more cyperus esculentus can be left on the plants, manual sorting is needed, and the rest cyperus esculentus is collected, so that the efficiency is greatly influenced.
