【摘要】为了提高花生联合收获机的清选性能,在测量分析花生摘果脱出物清选特性参数的基础上,设计了一种主要由轻杂物清理装置和断秆分离装置组成的花生荚果清选系统,前者采用横流风机以吸气方式清理待清选物料中的轻杂物,后者则根据荚果与断秆的径向几何尺寸差异将断秆分离出去.利用解析作图法对断秆分离装置进行受力和运动分析,得出了断秆顺利分离满足的力学关系,并通过理论计算得出了分离辊的结构参数.进行了室内变参数清选试验,研究了各结构运动参数对花生清选损失率和含杂率的影响,结果表明:在最佳工作状态下,该清选装置的清洁率可以达到99.38%,清选性能良好.%In order to improve the cleaning quality of peanut combine harvester,a new peanut combine harvester cleaning system was designed based on statistical analysis of cleaning characteristic parameters of peanut mixture.The system is mainly composed of light impurities cleaning device and stems separating device,the former used cross-flow fan to clean light impurities,and the latter used the radial geometry size differences of peanut pods and stems to separate stems from peanut pods.Force analysis of stems separating device was done by the means of graphic analysis, the request of stems being separated was obtained by the experiment,and the working parameters of separation roller were calculated.For the purpose to optimize related parameter of peanut
cleaning system and reduce impurity rate and cleaning loss rate,the per-formance test of peanut cleaning system was carried out.When peanut combine harvester cleaning system was under the best working state,the cleaning rate of cleaning device was 99.38%,and the peanut cleaning system was adaptable and reliable.
