摘　　要：我国玉米收获机普遍存在可靠性低、适应性差、可操控性低及自动化水平落后等问题,不能满足玉米收获季节性强、劳动强度高、作业量大等实际作业需求。液压系统具有布置紧凑、操作方便、故障率低等优点,非常适合应用于结构形态多变、工作条件恶劣的农业机械。为此,结合目前玉米生产现状和现有技术装备,设计了一种静液压驱动自走式玉米收获机,可一次性完成摘穗、输送、剥皮和秸秆切碎还田等作业。田间性能试验结果表明:该机操控简单、可靠性高,主要性能指标均达到或优于国家标准。At present our country ’ s corn harvester generally have problems of low reliability , poor adaptability , low con-trollability and lack of automation system .It can ’ t meet requirements of strong seasonality , high labor intensity and large operations of corn harvest .Hydraulic system has advantages of compact arrangement , low failure rate and comfortable to operate , which is very suitable for agricultural machinery .Combined with the current situation and existing technology , this article designs one hydrostatic self-propelled corn harvester .It is mainly composed by frame , header , front cutter , lift conveyer , corn husker , corn collection box , tillage machine , drive axle , engine , steering axle , hydraulic system and automation system .It can complete picking , lifting , peeling and straw chopping at one time .Field performance test re-sults show that this machine is easy to control with high reliability .Main performance indexes reach or exceed national standards .
