Vibrations in engineering and technology

Trukhanska Olena – Candidate of Technical Sciences, Associate Professor, Associate Professor of the Department of Agroengineering and Technical Service of Vinnytsia National Agrarian University (Solnechnaya St., 3, Vinnytsia, 21008, Ukraine, e-mail: seaswallow@ukr.net ).

The study of the technological process and design parameters of the tipping working tool was carried out. The most favorable conditions for plants are created when the cultured soil layer is differentiated by its structural composition. At the same time, clods with a size of 5 to 20 mm should prevail in the surface layer of the soil, and in the seed bed - from 0.25 to 10 mm.

Means of mechanization of soil cultivation in systems of zero, minimum and zero tillage, which provide the necessary conditions for growing agricultural crops, were analyzed.

It was established that in order to obtain a fine-grained structure of the soil in the area of seed placement, it is not necessary to grind it intensively and thereby increase the energy intensity of the process. The necessary structure can be obtained by combining the operation of grinding the soil and its fractional distribution along the processing depth.

The influence of the geometric parameters of the slope of the inclined disintegrator according to quality and energy indicators of zero tillage. A high concentration of these row crops leads to the accumulation of harmful weeds, diseases and pests.

It was determined that the use of tillage technologies on sloping fields, which are adapted to flat conditions and do not take into account the peculiarities of the relief, leads to intensive development of erosion processes. Modern tools for the main cultivation have their shortcomings: the chisel does not grind the soil enough and does not cut the roots of the weeds; a plow sole is created with a flat cutter; the plow not only creates a footing, but also covers the crop residue, turning the soil over, creating conditions for water and wind erosion. One of the ways to improve the quality of the main tillage will be the use of loose plows with inclined working bodies, which ensure high-quality loosening over the entire width of the tillage unit, eliminate soil compaction and leave stubble on the field surface.
