        Twin Tiger

The excavator works on soil.When designing and using excavators, we need to understand the basic characteristics of the soil and some basic knowledge of the soil cutting process.

The cutting part of a blade or bucket, the process of mechanically removing soil blocks or layers from the soil, becomes soil cutting.Soil cutting is a very complicated process.In the process of stripping the soil with a wedge-shaped edge, the soil is squeezed and shear, which means that the cut soil is loose and partially compressed.As a result, the damage resistance of the original soil structure, friction between soil and tool and friction between soil and tool are generated.When the soil is stripped off, it flows into the bucket.Friction exists between soil and soil and between soil and cutting device during the flow process.At the same time, the flow of soil is blocked by the back wall of the bucket, which also creates additional resistance.Therefore, in addition to the above cutting resistance, the mechanical cutting device can overcome these friction and additional resistance.When the bucket works, these additional forces form soil load resistance.The sum of cutting resistance and loading resistance is called digging resistance.For different grab, the ratio of soil bearing capacity and excavation resistance is very different.
