Dsesign of combine harvester high discharging automatic control system

针对联合收割机高位卸粮机构自动化操控问题,对联合收割机的机械结构、手工操纵流程、电路配置进行了研究。进行了卸粮二自由度机构及运动原理分析,并针对联合收割机工作效率低下问题进行了归纳,提出了一种联合收割机高位卸粮自动化控制系统;进行了二自由度机构作业任务操作逻辑次序优化,以及最小数量位置感应传感器系统和傻瓜式自动操作控制算法的设计,完成了相关软硬件设计和软件的开发,并进行了星光4LZ-5. 0Z履带式自走全喂入联合收割机现场测试与作业的对比实验。研究结果表明:自动卸粮机构操作用时5. 3 s,相比于人工调节用时降低了4倍,提高了卸粮效率,并具有卸粮操作简单、安全性好等优点。

Aiming at the problem of automated control of high-level grain unloading mechanism in combine harvester,the mechanical structure,manual control process and circuit configuration of combine harvester were studied,mechanism structure and movement principle analysis of unloading grain and two degrees of freedom were carried out,and the problem of inefficiency of combine harvester was summarized. A high automated unloading system control system of combine harvester was put forward to operate logic of two-order optimization,the minimum number of position sensor system and the fool automated control algorithm design,the completion of the relevant hardware and software were designed and development,and Star 4 LZ-5. 0 Z crawler self-propelled full-feed combine harvester field test and operation comparison were done. The results indicate that the automatic unloading mechanism takes 5. 3 s,compared with the manual adjustment time reduced 4 times,increase unloading efficiency,and has unloading grain simple operation,and so on.
