Abstract In order to solve the problem of blockage of the clamping conveying system for peanut combine harvester, a peanut vine clamping conveying system (PVCCS) with flow control scheme is proposed, and the system mathematical modeling of hydraulic system is presented based on its physical attributes. Taking Baisha peanut variety as the research subject, the reasonable field working speed and blockage pressure threshold of system is determined via the loading characteristics analysis under typical working speed conditions for the PVCCS. A control strategy with logic threshold approach is developed to avoid the system blockage during peanut harvesting with a reasonable field working speed. The field experimental results show that the proposed PVCCS and its control can meet the requirements of harvesting and avoid the blockage of system effectively.

花生联合收获机夹藤输送系统控制策略研究

摘要 为解决花生联合收获机夹持输送系统堵塞的问题，提出了一种带流量控制方案的花生藤夹持输送系统（PVCCS），并根据其物理属性对液压系统进行了系统数学建模。 . 以白沙花生品种为研究对象，通过PVCCS典型工作速度条件下的加载特性分析，确定系统合理的田间工作速度和堵塞压力阈值。开发了一种具有逻辑阈值方法的控制策略，以在合理的田间工作速度下避免花生收获过程中的系统阻塞。现场实验结果表明，所提出的PVCCS及其控制能够满足采收要求，有效避免系统堵塞。
