| 摘 要： | 为实现花生联合收获机的轻简化，设计了花生秧蔓夹持输送液压系统。基于花生联合收获机秧蔓夹持输送系统工作特点，分析了不同夹持输送速度工况下液压系统的工作性能。当秧蔓夹持输送系统驱动马达输入流量17 L/min时，随着秧蔓喂入，系统压力急剧升高，夹持链条出现严重的堵塞现象；当驱动马达输入流量20 L/min时，秧蔓喂入量较大时，系统偶尔出现压力升高点，压力升高点容易出现夹持链条堵塞的现象；当驱动马达输入流量23 L/min时，链条夹持秧蔓比较流畅，无堵塞现象。花生联合收获机秧蔓夹持输送液压系统工作特性分析，可为秧蔓夹持速度控制方法的研究提供理论依据。

| Abstract: | Hydraulic system of vine clamping and conveying was designed in order to achieve simplification of peanut combine harvester.Working performance of hydraulic system of clamping and conveying under different speed condition was analyzed based on working characteristics of hydraulic system of peanut harvester.Results showed that pressure of hydraulic system increased sharply with vine feeding increasing，and clamping chain was blocked seriously when input flow of driving motor of system was 17 L/min.System occasionally had a high-pressure point，and clamping chain would be blocked at high-pressure point when input flow of driving motor of system was 20 L/min.Clamping chain could be operated smoothly without blocking when input flow of driving motor of system was 23 L/min.Analysis on working performance of hydraulic system could provide a theoretical basis for control method study of clamping chain speed for peanut combine harvester. |
