Tillage machines with power-driven rotary tillage tools are promising in agriculture. These tools have become the subject of scientific research and industrial applications in modern agriculture. However, their further improvement is limited by the poorly understood process of their interaction with the soil. The aim of the study is to increase the efficiency of tillage process through the research, development and application of actively driven rotary tillage tools. For the study, three types of actively driven rotary tillage tools were selected: a cylindrical ring tillage tool, a knife tillage tool and a rotary tillage tool with covering elements. The article presents the results of work on the development of a laboratory soil bin for conducting experimental studies of the interaction of soil – tillage tools. During the study, the angle of inclination from travel direction can be adjusted stepwise to 40°, 70° and 90°. The inclination angle from vertical plane can vary between -30° (backward), 0° (vertical), +20° and +40° (forward). The coefficient of kinematic mode was studied in the range of 0.6≤λ≤1.4. The laboratory soil ben was designed according to technical requirements using the COMPAS-3D program. An expression was derived to determine the required kinematic coefficient of the rotary tillage tool when conducting research on the laboratory soil bin. Dependences were established between the coefficient of kinematic mode and the number of teeth on the interchangeable gear sprockets (gear ratio) of the drive unit of the soil bin. The study identified the transmission settings corresponding to the investigated range of the coefficient of kinematic mode of operation for the selected tillage tools. Thus, the developed laboratory soil bin allows for research on optimizing the parameters and operating modes of actively driven rotary tillage tools. this will improve tillage quality, reduce energy requirements and increase overall soil tillage efficiency.
