IMPROVEMENT OF THE OPPERATING EFFECT OF SMALL SELF-PROPELLED ROTARY TILLERS BY USING ADAPTIVE POWER EFFECIENT TOOLS

The article analyzes the ways and methods of improvement of the functioning of small self-propelled tillers. The main methods are based on the selection of the most optimal modes of tillage mills by changing the translational or angular velocity of milling drum. The necessity of adjusting the angle of the cutting milling drum is stated as important task for resolving this problem. Milling drum in a conventional cutting chip increases significantly the power consumed for cutting, as compared to the capacity of the upgraded tool whose blades have a constant cutting angle. The practical application of this body of work would reduce the energy intensity of milling drums at 30% while maintaining the specified agronomic requirements. The authors have proposed construction of new tillage tools with adjustable cutting angle, protected by patents of the Russian Federation.
