摘　　要：为了对比履带自走式分拣型马铃薯收获机与传统拖拉机悬挂挖掘铲式马铃薯收获机的作业效率和作业成本,根据相关标准设计了对比试验。通过对比试验,在各项作业质量指标都满足标准要求的情况下,履带自走式分拣型马铃薯收获机的作业总成本达到了传统轮拖+挖掘铲式马铃薯收获方式的同等水平,但作业效率提高了6%,人工成本节约了16%。同时验证了履带自走式分拣型马铃薯收获机在典型丘陵山区作业模式下,具有节约人工成本和降低劳动强度的优势;试验发现产品设计方面可对前振动输送筛网的振动频率和强度、输送筛网间隙、发动机功率等参数进行优化调整,以便更好地适应丘陵山区的马铃薯收获作业。In order to compare the operation efficiency and operation cost of the crawler self-propelled sorting potato harvester and the digging shovel potato harvester suspended by the traditional tractor, a comparative test was designed according to the requirements of relevant standards. Through the comparative test, under the condition that all the operation quality indexes met the standard requirements, the total operation cost of the crawler self-propelled sorting potato harvester reached the same level as that of the traditional wheeled tractor + digging shovel potato harvesting method, while the operation efficiency was improved by 6% and the labor cost was saved by 16 %. Through the comparative test, it was verified that the crawler self-propelled sorting potato harvester could achieve the advantages of saving labor cost and saving labor intensity under the typical hilly and mountainous area operation mode. Through the test, it was found that the product also needed to optimize and adjust the vibration frequency and strength of the front vibration conveying screen, the gap of the conveying screen, the engine power and other parameters in the design, so as to better adapt to the potato harvesting operation in the hilly and mountainous areas.
