Abstract

A hydraulic excavator is widely used in crushed stone quarries to perform many different operations. Previous research on material handling by excavators is most often based on laboratory testing and observation of soil materials and the digging forces in them. These results are very difficult to transfer to fieldwork during the quarrying process. Therefore, in this work, the energy consumption of an excavator while working in typical materials for a crushed stone quarry was investigated. The field measurements were performed on overburden, blasted rock material, boulders, and two different crushed materials. Energy consumption was observed only during the portion of the cycle in which the bucket digs the material. In this way, the energy consumption was mainly related to the properties of the material. The highest energy consumption was found for blasted rock material, lower in overburden, and the lowest for boulders and crushed materials. These results are important for organizing an optimal distribution of machines according to the work tasks in the quarry and ultimately for energy savings.

碎石采掘过程中挖掘机搬运物料的比能耗

液压挖掘机广泛用于碎石采石场，执行许多不同的操作。以往对挖掘机搬运物料的研究大多是基于实验室测试和对土壤材料及其挖掘力的观察。这些结果在采石过程中很难转移到现场工作中。因此，在这项工作中，研究了挖掘机在碎石采石场典型物料中工作时的能耗。现场测量了覆盖层、爆破岩石材料、巨石和两种不同的破碎材料。能源消耗仅在铲斗挖掘材料的部分周期中观察到。这样，能耗主要与材料的性能有关。爆破岩石材料能耗最高，覆盖层能耗较低，巨石和破碎材料能耗最低。这些结果对于根据采石场的工作任务组织机器的最佳分配并最终节省能源非常重要。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
