摘　　要：通过对中国花生收获机械调查分析,针对目前多数花生收获机配套动力大,损失率高,可靠性差、利用率低等现状,选择了常用的4H-2型、4HW-700型和4HW-800型收获机械作为试验研究对象。通过对这三种花生收获机的田间性能对比试验,分析了各机型的主要收获指标:总损失率、含土率、小时耗油量。证明了4H-2型花生收获机的性能均优于4HW-700型和4HW-800型花生收获机。经三种花生收获机的对比试验分析,为花生收获机的理论研究与优化设计提供了参考,也为花生联合收获机的研制开发提供了新的思路。对该类收获机的大面积推广应用提供了很好的素材。The mechanization level of peanut harvesting is lower than those of other crops, and it is concluded that the loss rate is higher, the reliability is worse and utilization efficiency is lower, through investigation and analyses of the mechanized harvesters for peanut at present in China. Three types of peanut harvesters, i.e., 4H-2, 4HW-700 and 4HW-800 peanut harvesters were selected as research objects. Through comparative field experiment on the performances of the three types of peanut harvesters, the dominant factors including total loss rate, soil content and fuel consumption per hour, which control peanut harvesting targets, were analyzed. Experimental results prove that the performance of 4H-2 type peanut harvester is superior to those of the 4HW-700 and 4HW-800 peanut harvesters. The results of comparative test and the analyses of the three types of peanut harvesters, provide the basis for theoretical research and optimized design of peanut harvesters, and also offer new methods for research and development of peanut combine harvesters. Moreover, the study provides better references for popularization and application of these kinds of peanut harvesters.
