THEORETICAL JUSTIFICATION OF CONSTRUCTIVE AND REGIME PARAMETERS OF THE UNIT FOR PROCESSING OF ROW-SPACINGS AND TRUNK STRIPS OF FRUIT PLANTINGS

abstract 1511907020 issue 151 pp. 232 – 243 30.09.2019 ru 12
Reserves of expansion of the areas under fruit plantings in the central part of the North Caucasus are limited, one of solutions of this problem is involvement in an agricultural turn and, in particular, under fruit plantings a little or the slope lands, absolutely inconvenient for one-year cultures, having optimum climatic conditions. Currently, scientifically based technologies of cultivation of gardens on slopes are developed for foothill and mountainous areas of the North Caucasus in relation to zones. Large corporations, as well as medium and small business are engaged in production of fruits in the North Caucasian Federal District. One of problems which vendors of fruits face it is the shortage of the equipment on care of trunk strips and row-spacings of fruit plantings. Mechanized technologies of flat gardening are a little effective in specific conditions of mountain and foothill agriculture where the main limiting factor is the soil fertility. At the same time, the question of the accelerated creation of a humic layer in the trunk strips, improvements of the water and food modes of fruit plantings on slope lands is particularly acute. The carried-out analysis of a system of maintenance of the soil in gardens showed that the most rational is the cespitose and humous system providing bevelling of vegetation with its leaving on the surface of the soil in the form of mulch. However, lots the mower-grinders produced by the industry have rather low rotating speed of a rotational operating part (540 … 840 min-1); they do not provide high-quality crushing of grass vegetation, are incapable to transport crushed grassy masses in trunk strips of fruit-trees. In this regard, we offer a construction of a unit for processing of row-spacings and the trunk strips of fruit plantings. As a result of the conducted theoretical researches, we have set rational values of key parameters of the offered unit

THEORETICAL JUSTIFICATION OF CONSTRUCTIVE AND REGIME PARAMETERS OF THE ARABLE AND MILLING UNIT

abstract 1521908023 issue 152 pp. 275 – 287 31.10.2019 ru 10
Pre-planting preparation of soil in the Central part of the North Caucasus according to the traditional technology of cultivation of crops involves the use of single-operation soil processing machines and aggregates. As a result, they have to make multiple passes, resulting in increased energy consumption, soil compaction, and the emergence and development of erosion processes. In addition, the agricultural machinery used is characterized by the low operability and reliability of the working elements and their joint assemblies, which leads to a decrease in productivity, so that the agricultural requirements for the process of pre-sowing soil preparation are often not met. In order to solve the above-mentioned problems, an arable milling unit for pre-sowing soil preparation is proposed. Its structural and technological scheme is justified. The distinctive features of the proposed design are the possibility of the main soil treatment with simultaneous grinding of large soil clumps, lumps, plant residues and levelling of the soil surface; possibility of changing the installation angle of the rotary grinder and depth of soil treatment depending on the type of treated soil; high quality of soil preparation for sowing; provision of energy consumption reduction due to combination of technological operations in preparation of soils for sowing; lack of expensive assemblies and parts; the need for less energy for aggregation when preparing soils for sowing. As a result of the theoretical studies carried out, rational values of the main parameters of the proposed arable milling unit have been established, which have a decisive influence on the process of its operation: speed of movement 1.5... 2.0 m/s; Angle of attack of working element 20... 300; Angular rotation speed of the working tool 20... 25 s-1

SUBSTANTIATION OF CONSTRUCTIVE AND TECHNOLOGICAL SCHEMES OF THE COMBINED TILLAGE UNIT FOR SEEDBED PREPA-RATION

abstract 0991405091 issue 99 pp. 1304 – 1314 30.05.2014 ru 964
The article analyzes the existing classification of leveling devices and their design features. We have found that currently the form of the seed layer is achieved with harrowing cultivation in 2 ... 3 tracks , leveling and packing rollers in 3 ... 4 passes units on the field, which leads to an increased cost of fuel, living labor, as well as compaction of arable and subsoil layers of the soil. We have also proved a constructively scheme of a com-bined device capable to form the seedbed in accordance with agronomic requirements in a single pass

OPTIMIZATION OF PARAMETERS AND WORKING HOURS OF MILLING WORKING BODY OF THE UNIT FOR PROCESSING OF ROW-SPACINGS AND SPACE AROUND FRUIT PLANTINGS

For further increase in production of fruit products, there are long-term plans of development of agriculture of the Russian Federation provide laying of new gardens of intensive and superintensive types. In this regard, development of slope lands and their use under gardens is a current social and economic problem. In the Kabardino-Balkarian Republic there are over 10 thousand hectares of intensive and superintensive gardens now. Therefore, large corporations, as well as medium and small business are engaged in production of fruit. One of problems which producers of fruits face it is the shortage of the equipment on care of row-spacings and spaces around fruit plantings. The mechanized technologies of flat gardening are a little effective in the conditions of slopes where the main limiting factor is the soil fertility. At the same time, the issue of increase in fertility of the soil in space around fruit plantings, improvement of the water and food modes of fruit plantings on slope lands is particularly acute. Thus, improvement of technology and development of a new design of the unit, providing performance of several interconnected technological operations for processing of row-spacings and space around fruit plantings, preservation and increase in fertility of soils on slope lands is relevant in the conditions of mountain and foothill gardening Central the North Caucasus. As a result of the carried-out analysis of technological processing of row-spacings and space around fruit plantings and results of theoretical researches (as criterion of optimization) the quality of dyeing of the soil is accepted. Speed of movement of the unit, angular speed of rotation of a mill and the angle of installation of knives have the greatest impact on criterion of optimization. As a result of carrying out a multiple-factor experiment, we have established the optimum values of the specified factors providing the maximum quality of dyeing of the soil
