Abstract

Introduction. In order to the road to be durable at the minimum necessary cost for its construction, the topsoil should be carefully removed without disturbing the soil located under the topsoil. The problem of cheapening the roads construction without reducing their quality can be solved by creating a continuous unit for the formation of the underlying layer. The main working elemens of the unit are shovels. The blade of the cantilever knife fixed on the shovel cuts the topsoil from the bottom. It is located at the angle of 45 ° to the direction of movement of the shovel and also has a sharpening angle. The front angle of the blade of the cantilever knife.The method of research. The cantilever knife is divided into the elements: the edge of the blade, the upper face of the blade, the surface of the cantilever knife, a lower plane. The consecutive impact of many cantilever knives on the ground within the operating unit width with the ground of one notional cantilever knife at a distance necessary for the excavation of one cubic meter of soil was replaced. The interacting forces of a notional cantilever knife with soil are called notional forces. The methodology of calculating energy costs when penetrating the edge of the blade of the cantilever knife into the soil is presented: to separate a layer from the body of the soil, to create a gap in the body of the soil, to overcome the friction of the soil against the edge of a blade of a cantilever knife. The total energy consumption during the interaction of a edge of a blade of a cantilever knife in the soil excavation with a volume of one cubic meter was obtained by adding the particular energy consumption.Results. Based on the developed calculation method, the distance at which a cantilever knife has to move to excavate one cubic meter of soil, and the time of this movement determined. The energy costs are calculated when penetrating the edge of the blade of the cantilever knife into the soil: to separate a layer from the body of soil, to create a gap in the body of soil, to overcome the friction of the soil against the edge of a blade of a cantilever knife. The total energy consumption and their structure during the interaction of the edge of a blade of a cantilever knife with the soil during the soil excavation with a volume of one cubic meter are determined.Conclusion. The total energy consumption during the interaction of an edge of a blade of a cantilever knife with the soil during the development of soil with a volume of one cubic meter is about 7 thousand J/cubic meter. In the energy costs structure during the interaction of an edge of a blade of a cantilever knife with the soil, energy costs prevail to overcome the friction of the soil against an edge of a blade. To determine the total energy consumption for cutting soil with cantilever knives shovels of the unit for removing the upper soil layer from the underlying layer of a road, it is necessary to analyze the interaction of other elements of cantilever knives with the soil.Financial transparency: the authors have no financial interest in the presented materials or methods. There is no conflict of interest.
