Abstract

ABSTRACT The decision-making capability of the machine to harvest grains must consider a lower fuel consumption with a higher operating velocity allied to a greater performance of the grain cleaning system, along with lower rates of the damage and waste produced. This study aimed at evaluating the operational performance and the energy efficiency of two axial harvesters, having different trail and separation systems in the soybean seed harvest. The experiment was carried out in a completely randomized block design in 500-m bands, consisting of two factors, namely two axial harvesters (single and double rotor) and six target velocities (3, 4, 5, 6, 7, and 8 km h-1). Regarding the operational energy performance, the hourly fuel consumption, operational speed, operational field capacity, fuel consumption per area and mass of the harvested grain, and the handling capacity of the harvest were evaluated. The harvesting performance parameters, such as the percentage losses in the platform and the trail system, broken grains, impurities, and the pods, which did not undergo threshing, were evaluated. The results obtained showed that the single-rotor harvester had a better energy efficiency, while the double-rotor harvester had a better operational performance. The double-rotor harvester was agronomically more efficient.

单、双转子轴向收获机在大豆种子收获中的运行性能和能效

摘要机器收割谷物的决策能力必须考虑更低的燃料消耗和更高的运行速度，以及更高的谷物清洁系统性能，以及更低的损坏率和产生的废物。本研究旨在评估两台具有不同试验和分离系统的轴流式收获机在大豆种子收获中的操作性能和能源效率。该实验在500-m波段的完全随机区组设计中进行，由两个因素组成，即两台轴向收割机（单转子和双转子）和六个目标速度（3、4、5、6、7和8km h-1）。关于操作能量性能，评估了每小时燃料消耗量、操作速度、操作田间容量、收获谷物的单位面积和质量的燃料消耗量以及收获的处理能力。对收割性能参数进行了评估，如平台和试验系统中的损失百分比、破碎的谷物、杂质和未经过脱粒的豆荚。结果表明，单转子收获机具有较好的能量效率，而双转子收获机则具有较好的作业性能。双转子收割机在农业上效率更高。
