Rotary tiller into the soil depth

The depth of the rotary cultivator into the soil is generally less than 10% to 20% of the radius of the rotary tillage parts, taking into account the corresponding unit energy consumption required for the radius of the rotary tillage parts, the rotary tillage knife wheelbase should be made to the bottom. Some designs are based on the relative relationship between the rotary tillage parts and the ploughing depth, and the central governor is directly installed on the shaft of the rotary tillage parts. This ensures minimum energy consumption of farm tools, minimum material consumption and good working quality. Most of the blade curves of rotary cultivators use archimedes curves, and other isometric logarithmic curves and sinusoidal exponential curves are also applied. Chinese scholars have proposed a variety of edge curves, such as energy-saving edge curve design, planar and surface type aspect design, radial spiral as a curved wire design to generate transition surfaces, etc.
