Abstract
The paper highlights the influence of the angle of sharpening of tillage working bodies and their theoretical justification. The work is of a research nature, expressed in the fact that a theoretical analysis of the method of determining the angle of sharpening of tillage working bodies by their degree of wear is given. The type of construction is proposed and described. As a result of this work, the angle of sharpening of the working bodies and the influence of wear on the traction resistance of the blade plough are theoretically proved. The conclusions present the main results achieved so far.
Highlights
Deep loosening is used with soil-free tillage units in areas with high humidity and soil treatment is performed by flat-cut working bodies in areas subject to wind erosion
The quality and traction resistance is affected by the preparation of all working bodies of the arable unit
The blade, figure 1b, in the thickness of the profile consists of a chamfer on the front side, since α0 = ≥ 90D − φ there is no sliding of soil particles when inserting the blade with such a profile. This fact indicates that a seal is formed, which leads to partial braking of the working body in this zone, and this in the complex of working elements of the plough affects the traction resistance of the entire plough unit
Summary
The quality and traction resistance is affected by the preparation of all working bodies of the arable unit. Many factors depend on the quality of sharpening of working bodies up to the traction resistance of the arable unit.
