大白菜收获机研究现状及发展对策OA北大核心CSTPCD

Combining the planting characteristics of different regions in China,the design and development of Chinese cabbage harvesting machines has become an important task for mechanized production of Chinese cabbage in China.This paper mainly introduced the major Chinese cabbage harvesting equipments at home and abroad,and described their main working structure and basic performance parameters.At the same time,the paper expounded the main cultivation methods for Chinese cabbage at present and put forward several issues facing the mechanized harvesting of Chinese cabbage at present,including the mismatching between foreign machinery and local agronomy,disunity of domestic planting agronomy,scattered planting scale and low economic benefit,etc.The paper also proposed countermeasures for future development,such as uniforming planting pattern;designing key components of machine to improve harvest quality and reduce harvest damage;conducting machinical generalization and automation design to improve processing and manufacturing and reduce cost,etc.
