“…In order to increase the efficiency and more fully load of an energy-saturated tractor of the third class, it is proposed to use in a single unit a harvesting machine and a haulm chopper (Figure 1) [6][7][8]. The weeder is hanged on the rear hinge of the tractor and its active working parts drive is performed by a power take-off shaft.…”

Potato production in the Russian Federation and in many countries of the world is important. In the public sector, potatoes are cultivated on farms, personal and subsidiary plots. In connection with the transition to market relations, the area for planting potatoes has sharply decreased, and as a result, the production of potato harvesting equipment. Therefore, an acute question arose of the further creation and production of the simplest potato harvesting equipment and the improvement of their new working bodies. Pre-harvest removal chopping tops occupies an important place in the technology of potato cultivation. During operation, it was noted that rotary machines have a number of disadvantages caused by the imperfection of the rotor design, its kinematic modes, insufficient balance and reliability. In order to eliminate these shortcomings, a rotary topper with a vertical axis of rotation was designed and manufactured. To justify the design and operational parameters, theoretical studies of the process of interaction of the working element of the chopper with the tops of root crops were carried out, as a result of which the main patterns characterizing the working element were identified. In particular, dependence was obtained that allows to determine the cross-sectional diameter of the working element, which takes into account both the design parameters of the developed grinder and the properties of the tops. After calculating the obtained dependence, it was determined that for the operation of the unit with a minimum energy consumption, the diameter of the working element should be 6 mm. Such a working element cuts the tops in compliance with all agricultural requirements. Field experiments conducted later confirmed the obtained value, which indicates the reliability of the results.

“…При выкапывании картофеля лемех картофелеуборочного комбайна движется со скоростью до 6 км/ч, а для полного крошения почвы необходимо ее увеличение до 12…14 км/ч [1,2,3], что приведет к повышению тягового сопротивления и повреждению клубней [4,5]. С учетом того, что при уборке картофеля необходимо не полное крошение поверхностного слоя почвы, а только разбивание ее комьев, энергия воздействия может быть уменьшена [6,7,8].…”

Potato harvesting is an important process in crop growing technology. When implementing it, it is not necessary to completely crumble the surface layer of the soil, but only to break up its clods, which is achieved by introducing a spring into the design of the ploughshare. During translational movement, a force arises directed in the opposite direction, which compresses the spring. When the force acting on the ploughshare decreases, it expands, and when it increases, it contracts. The resulting vibrations are transmitted to the soil clods and, with sufficient force, their destruction occurs. Vibrations of the share lead to a change in its kinetic energy. Instantaneous energy increases and decreases, while the average energy remains constant. More complete information about the interaction of the ploughshare with the surface layer can be obtained through mathematical modeling. The purpose of the study is to determine the compression coefficient of the spring. The simulation is based on solving Lagrange equations of the second type in the Cartesian coordinate system with initial and boundary conditions determined by the design of the ploughshare. When compiling a mathematical model, the following were taken into account: – the gravity of the ploughshare; – gravity of the soil layer; – the elastic force of the spring, which creates additional vibrations; – cutting force of the soil layer; – the friction force of the soil layer on the surface of the ploughshare, – the normal reaction of the supporting surface of the ploughshare and the angle of its entry into the surface layer. Modeling made it possible to determine changes in the instantaneous value of kinetic energy, which ranges from 0 to 3.6 J. The optimal amplitude of oscillation of the share during forward motion at a speed of 6 km/h was 0.02 m. The spring stiffness coefficient for loamy soils of the Ryazan region should be in the range of 2200…3000 N/m.
