Optimization Design of Shovel Depth when Loader Shovelling Original Raw Soil

Abstract

The shovel depth generally references to the depth of material pile operation, or according to operators’ experiences to determine the depth while loader shovelling original raw soil. In view of this situation, the relationship between the shovel depth of loader bucket and shovel resistance is analyzed in this paper, and a mathematical model is constructed for calculating the time of the material filling up the bucket. Taking ZL50 loader as an example, and combined with the relationship curve of the bucket work resistance and the shovel depth, and the traction characteristic curve of I gear, the relationship of the driving speed and shovel depth is worked out, on the basis of this, the mathematical model of optimization algorithm of the shovel depth is established. The result shows that there is an optimal shovel depth when loader shovelling original raw soil, while the operation efficiency of loader is the highest, and there is a best operation depth range of loader shovel, in which work efficiency of loader changes a little, this will bring great convenience to the operation for the driver. DOI: http://dx.doi.org/10.11591/telkomnika.v11i8.3090
