4YA-4A型自走式玉米收获机设计与试验
Design and test of 4YA-4A self-propelled corn harvester
摘要
Abstract
To address issues such as low operational efficiency,high field losses,and poor adaptability to different working conditions in corn harvesters,a 4YA-4A self-propelled corn harvester was designed.This machine was capable of completing multiple processes in one pass,including ear picking,conveying,husking,grain collection,and straw chopping and returning to the field.Its working principle was briefly described,with a focus placed on the design and analysis of key components such as the header,husking device,elevator,and grain tank.The structure and parameters of each key component of the harvester were determined.Field tests showed that the harvester achieved a total loss rate of 1.69%,a grain impurity rate of 0.11%,a kernel breakage rate of 0.49%,a husk removal rate of 96.7%,and a qualified straw chopping length rate of 90.9%.It was able to complete mechanized corn harvesting efficiently with low losses,providing equipment support for low-loss and high-efficiency mechanized corn harvesting.关键词
