摘　　要：针对已研制的平贝母收获机作业后含杂率较高的问题,以平贝母为研究对象,通过区组试验获得了不同平贝母类型、不同含水率以及不同放置方式下平贝母的极限挤压载荷力。试验结果表明:平贝母类型、放置方式以及含水率对平贝母极限挤压载荷力影响显著;4种类型的平贝母所受极限挤压载荷力大小的关系为“大贝”>“大平头”>“大豆子”>“桃贝”,3种放置方式所受极限挤压载荷力大小的关系为正放>侧放>立放;3个含水率所受极限挤压载荷力大小的关系为54%含水率>61%含水率>66%含水率,研究结果可为平贝母收获机研制二次筛分装置、降低含杂率提供参考。Aiming at the problem of high impurity content of Fritillaria harvester,the ultimate extrusion load of Fritillaria under different types,moisture content and different positions was obtained by block test.The results show that the types of Fritillaria,the position and moisture content have significant effects on the ultimate extrusion load force of Fritillaria;the relationship between the ultimate extrusion load force of Fritillaria of four types is Dabei,Dapingtou,Dadouzi,Taobei.The relationship between the ultimate extrusion loading force of three positions is significant.The crack image analysis of Fritillaria showed that the relationship between the damage degree of Fritillaria and the ultimate extrusion load on the three moisture contents was 54%content>61%content>66%content.The relationship between the damage degree of Fritillaria and that of Fritillaria was forward>side>vertical.The research results can provide reference for the development of secondary separation device for Fritillaria harvester and the reduction of impurity content.
