Increasing the Efficiency of Using a Potato Digger With an Automatic System in Variable Soil Conditions

The article discusses the issues of reducing soil compaction when harvesting potatoes with an automatic system for regulating the internal tire pressure of the running wheels of a potato digger. As a result of the influence of the propulsors and the running system as a whole, a change in the soil structure occurs, not only in the rut itself, but also in the areas located next to it, which indicates the nature of the spread of soil deformation and its influence on the condition of soil covers, which ultimately leads to a decrease in yield. (Purpose of the study) Reducing soil compaction on waterlogged soils by automatically adjusting tire pressure depending on soil moisture. (Materials and methods) A potato digger with an automatic system for regulating the tire pressure of running wheels has been developed. (Results and discussion) The reduction in soil compaction occurs due to the fact that it is additionally equipped with a capacitive sensor for measuring soil moisture, made in the form of a wheel, where, with reduced humidity, a signal is sent from the capacitive sensor to the automatic pressure control system to increase the tire pressure in the running wheels. from the air supply tube under pressure, air enters the chamber of the running wheels of the potato digger; at high humidity, a signal is sent from the capacitive sensor to the automatic pressure control system to reduce the internal tire pressure in the running wheels; the air leaves the wheel tires of the running system of the potato digger through the outlet into the environment and reduces tire pressure. (Conclusions) As a result of automatic tire pressure changes, the density of the soil in the wheel track is significantly reduced, thereby preventing soil compaction.
