Развитие мобильной энергетики с учётом агротехнологических ограничений

Abstract

The problem of finding the optimal ratio of mass, power, and working speed has been and remains an urgent task since laying the groundwork of agricultural mechanics. The concept of development aimed at increasing the productivity and operating speeds of machine-tractor units, has led to an increase in unit power and the mass of machines. An analysis of the development trends of tractors and self-propelled machines showed an annual increase in the average power of newly designed tractors by 2 to 4 hp. Capacity implementation of equipment with increased energy saturation is possible due to an additional increase in the mass of machines, which results in increased soil compaction. Critical stresses reaching a significant depth do not contribute to the process of complete relaxation of the soil. In the uncultivated layer, a soil horizon is formed between 25 to 30 and 100 to 120 cm (with a hardness corresponding to a clay rolled road), limiting the development zone of the plant root system and disturbing soil filtration. The intensive use of energy-saturated units and self-propelled machines has led to the accumulated overconsolidation of the uncultivated layer of more than 60% of arable land. Soil overconsolidation along the wheel track leads to a decrease in the yield of grain crops by 10% and root crops by 20%. When modernizing or designing new models of machines, we suggest taking into account the negative environmental consequences of the use of units in the feasibility study and reworking the regulatory and methodological documents for assessing the specific pressures on the soil of the running gear parts of self-propelled machines. It is necessary to reduce the machine load on the soil by using smaller machines and by implementing measures to loosen the subsoil horizon. Equally important is to determine the parameters and design a line of robotic energy systems, a set of working equipment and a control system based on the principles of multi-agent control of sets of dynamic objects in relation to agricultural production.
