针对丘陵山区前胡收获工作效率低、劳动强度大、无专用机型等问题，设计了一款联合式前胡收获机。在阐述前胡收获机整机结构和工作原理的基础上，结合前胡收获农艺要求，对挖掘装置、输送装置的结构及工作参数进行了理论分析与结构设计，确定收获机挖掘装置和输送装置的结构与工作参数。对振动装置、分离装置工作过程的临界状况进行受力分析，确定收获机振动筛和圆筒筛工作参数范围。以工作效率、损失率、损伤率和含杂率为指标，对收获机样机进行了田间试验。结果表明：收获机以最小前进速度0.8 m·s-1和最大前进速度1.2 m·s-1作业时，工作效率分别为0.19和0.28 hm2·h-1，损失率分别为3.56%和3.62%，损伤率分别为2.83%和2.79%，含杂率为3.28%和3.67%。前胡收获机各项工作指标符合行业标准。研究结果可为根茎类作物收获机械的设计提供参考。
Aiming at the problems of low work efficiency, high labor intensity and lack special machinery for Radix peucedani harvesting in hills and mountains areas, a combine Radix peucedani harvester was designed. Combined with the harvesting agronomy of Radix peucedani, the structure and working parameters of the excavation device and conveying device were theoretically analyzed, and the structure and working parameters of the harvester excavation device and conveying device were determined. The limit conditions of the working process of the vibrating device and separation device were analyzed, and the working parameter range of the vibrating screen and cylindrical screen of the harvester were determined. The field test of the harvester prototype was carried out with the working efficiency, loss rate, damage rate and impurity content as the indexes. The field test results showed that: when the harvester operated at the minimum forward speed of 0.8 m·s-1 and the maximum forward speed of 1.2 m·s-1, the working efficiency was 0.19 and 0.28 hm2·h-1, the loss rate was 3.56% and 3.62%, the damage rate was 2.83% and 2.79%, and the impurity content was 3.28% and 3.67%, respectively. All work indexes of Radix peucedani harvester meet industry standards. This study can provide a reference for the design of rhizome crop harvesting machinery.
