Constructive-technological parameters of a hopper feeder have been established. They help to synchronize feeder’s flow and feed consumption by animals. Synchronization of these factors eliminates the initial cause of feed loss during fattening. It was found out that the main influence on feed loss is exerted by shape and geometrical parameters of feedstuff fill at the bottom of feeder, which depend on their physical and mechanical properties and on the feedstuff level in a hopper feeder. The fill balance condition at the bottom of a feeder is provided by compensation of feedstuff weight pressure inside a hopper due to the weight of a surcharge layer. The thickness of layer is proportional to the height of feedstuff volume inside a hopper and does not depend on technological gap between discharging feed line and the bottom of a feeder. It is found out that the discharging feedstuff is distributed throughout the bottom of a feeder. There is a central nonmoving area in the cone shape in alignment with the axis of the discharging feed line. This area functions as a shutter, which reduces the effective area of discharging channel. It is determined that the flow of feedstuff is set by adjusting the technological gap between discharging feed line and its bottom within defined limits. In accordance with physical and mechanical properties of feed this dependence of feedstuff flow allows to determine corresponding functional parameters of discharging feed line in order to meet the needs of a group of fattening animals
The article presents a study of parameters and modes of operation of machines for soil cultivation. In determining the parameters and modes of operation of machinery for tillage we have applied the theory of similarity and dimensions of physical quantities. We have obtained the regularities of disclosing the relationship of the parameters from the medium to the energy characteristics of the process. As the initial data we used test protocols of machines for soil cultivation (Central - Black Earth, Kubanskaya, Sibirskaya, of North - Caucasion MIS, RosNIITiM) : KPI - 3.8, AРC - 3.9, AKV - 4, AKM - 6 - V, AMP - 4 APC - 4 A, AРC - 10 APR - 4.4, APU - 6.5 APSH - 6 , CNC - 6.0, CSТ - 3.8, APC - 4. We defined the formula оf dimension parameters and modes of operation of machines for soil cultivation and properties of soil (traction resistance, depth, width, speed, hardness of the soil, acceleration). Based on dimension theory we have received similarity criteria. Based on the correlation analysis and the least squares method we determined the nature of addiction and the coefficients for it. We have also received a graph for determining the operating modes and parameters of machines for soil cultivation
In the article, there are basic elements of the concept,
the structure and the group methods of crime
investigation. A brief analysis of the views of scientists
towards the issue was performed. The author comes to
a conclusion about the content of the group
methodology and makes a theoretical justification of
the expressed positions. We identify three separate
base isolation system classification - group
investigation techniques: a) the difference in the
structure of private and group techniques; b) the
similarities in the criminal - legal and criminological
characteristics of crime groups; similarities in the
process of crime investigation and scientific - practical
recommendations for their investigation
The assessment of quantitative signs of plants of peas and comparison of hybrid lines of leafless peas and leaves morphotypes is carried out. Lines of peas which are more productive and most adapted for the south Rostov region conditions were allocated as a result
Considering the nature of the development of sod, gemmation resumption for a period of unfavorable conditions, types of shoots, their vegetative mobility and placement in terms of ecological niches rhizomatous grasses are divided into rhizomatous, rhizome-loosely-turf and sod-rhizomatous biomorphological types, that stand out the specifics of environmental and biological characteristics forming generative, elongated, lateral shoots and roots, differing features of morphology, anatomy, biochemistry and phytocoenology forming continuous grass stand
The article discusses structural schematics power circuits and voltage stabilization systems of converters with improved operational and technical characteristics
The authors’ classification of expenses and elements in system of controlling and management accounting is presented in the article
The article considers the problem of creating an effective system of teacher training engineering school. We have analyzed the main challenges of professional activity of a teacher in terms of innovative changes in the system of higher engineering education. The analysis of approaches to training high school
teachers in the national education practice was done; we have also identified the main trends and features of its development in technical universities as well as the principles and conditions of formation of professional and pedagogical competence of the engineering faculty in the system of higher, postgraduate and additional professional education
In the article we have considered the concept of integrated corporate structures, the term of "corporation", "holding"; we have proposed the evaluation of their development in the Krasnodar
region. The review of current management problems in agro-industrial holding was provided as well as the choice of directions of improvement of management, which is the basis for the integrated management techniques for integrated corporate structures of such forms, on the example on "Southern Diversified
Corporation" agricultural holding
Statistical analysis of the dynamics and structure of agricultural production in the Krasnodar Region is carried out: social and economic indicators, the place of agricultural production in the gross product of the region, the dynamics of quantity of agricultural organizations, the growth rates of volumes of physical production, and the efficiency of agricultural production are examined. The agricultural production of the region is analyzed in the context of individual industries and a comparison of regional indicators with data for the Southern Federal District and the whole country is made. The structure of sown areas and yield of agricultural crops, as well as the dynamics of gross harvesting of their main types are considered. The main vectors for the development of livestock and crop production have been identified. The main problems and trends in the development of crop and livestock sectors in the region are identified. The author of the article, based on the analysis of the economic potential of the region, in particular the agro-industrial complex of the region as the country's largest producer and supplier of agricultural products and raw materials, justifies the role of the agricultural production of the region and its ability to meet the needs of the population under conditions of import substitution in the Krasnodar Region and the whole country. The article has research nature, expressing the fact that it offers priority directions for increasing the efficiency of agricultural production in the region
