The work was carried out not only in the scientific, but
also in practical directions, the key part of which was
the modeling of the system. Consideration of the
presented modeling processes occurred on the basis of
the delivered pedagogical experiment associated with
the introduction in the discipline "Engineering
Graphics" of a new tool for the military educational
institution to obtain the final graphic design document.
The purpose of the experiment included a comparative
analysis of modeling tools (manual and machine) and
their impact on the production of the final product
(drawing). As a tool, the computer-aided design
system Кompas-3D was used. The presented research
was worked out in practical classes of the specified
discipline, the theme of one of them was "Image of
thread and threaded connections". With the help of the
graphic editor Compass-3D, a model of the shaft and
bushing with the specified thread profile was obtained,
as well as the assembly unit based on them. The entire
way of obtaining the above objects for convenience
and ease of perception has been broken down into
certain stages. The results of the pedagogical
experiment were very satisfactory; the goal of the
practical training was fully achieved
Results of the research on ecological safety of utilizing high clearance tractors for cultivation and harvesting of high stalk plants are presented. Purpose of the research was to decrease damaging of high stalk plants during multi-pass harvesting by tractor parts. For increasing efficiency and competitiveness of high stalk plants decreasing prime cost of production, increasing profitability and labor productivity are required. This can be achieved by introducing complex factors, which together with other factors as complex technological and technical modernization are required. Basic direction of modernization is utilizing completely new technologies and renewal of machines. Modern tractors utilized for tobacco growing have been analyzed. Basic demands for high clearance tractor which can be used for tobacco, grape and fruit trees growing have been developed. Researches on studying the tobacco plant folding during harvesting have been carried. Scheme of high clearance tractor MTZ-80 which can be assembled with machines for multi-pass harvesting of high stalk plants without their damaging has been developed. New scheme for modernization tractor MTZ-80 into high clearance model has been proposed. It can be done by changing speed reducers and forward wheels with size 11,2x20 on size 11,2x28. This will increase clearance from 470 to 840 mm
Nowadays, in Russia the problem of utilization of self-propelled vehicles has not been solved yet. This problem remains because in Russia there is no accurate system of cooperation between developers, producers and customers of mechanical products. The article analyses Russian and foreign experience in solving this issue, gives brief information about working out Russian system of agricultural machines utilization
The content of metals in raw rice is determined.
Inversion voltammetry (IVA) was carried out in an
accredited laboratory on the "Ta-Lab" device of the
company "Tom-Analit" LLC according to the
approved method of ERD F 16.1: 2: 2.2: 2.3.46-06.
Silicon dioxide is determined according to ERD F
16.1: 2: 2.2: 3.65-10 and humidity according to GOST
5180-2015. Preparation for the IVA is illustrated.
Voltammograms of the potential difference of the
chloride-silver reference electrode are compared with
the current strength of the indicator mercury-film
electrode of electrochemical cells. It has been
established that the main metals of the raw rice called
Regul grown in the Krasnodar region are: copper 1.6 ±
0.4 mg/kg, plumbum 1.4 ± 0.4 mg/kg, zinc 1.9 ± 0.5
mg/kg, iron 95 mg/kg, manganese 5.2 ± 1.3 mg/kg and
silicon dioxide 6.5 mg/kg. The presence of iron is
associated with the wear of gravity. The content of
zinc, manganese and silicon dioxide corresponds to
this type of grain. The presence of copper and lead is
associated with the absorption of heavy metals from
the soil
One of perspective variants of development of the
meat industry can become the production of
foodstuffs from untraditional kinds of the meat raw
materials such as the rabbit meat, which has a high
protein content with a full number of essential amino
acids, broad spectra of the mineral substances and
vitamins and reduced fat content. Therefore, a
demand on the rabbit meat has been increased
significantly in the past years. Rabbit meat is widely
used in various culinary dishes of the dietary
nutrition. Rabbit meat is used in limited scales for
production of sausages. The production of the
delicacy sterling foodstuffs from the rabbit meat, that
are capable for long-term storage, is almost not
developed. The regulated requirements for quality of
rolls that are included in Technical Conditions are set
up in accordance with the developed recipe and
technology of production of the smoked-boiled rolls
from the rabbit meat. All the foodstuff samples gained
high scores on the organoleptic estimation. The
foodstuffs satisfy the requirements for chemical
composition: mass fraction of protein – no less than
20%, mass fraction of fat – no more than 25%, mass
fraction of moisture – no more than 65%. The
developed delicacy foodstuffs have a high nutritional
and biological value
The systemic links that depend on mechanization, which affect the growth of the cost price of field crop production were proposed and their analysis was made. Three main blocks of the basic reasons for production costs growth (machinery and materials cost rise, agroecological potential underutilization, agrotechnologies non-observance) disclose agricultural machinery and agrotechnologies of field crops negative aspects that are being used, and also explain agro-potential underutilization causes on the example of the Krasnodar region. The irrational nomenclative list of machines in the current system was analyzed, which not only raises field crop production cost price, but also negatively affects the soil fertility due to its reconsolidation and spraying. Requirements for production processes mechanization means, taking into account their cost price reduction, were formulated. The possibilities for optimizing of the field works timing performed by the proposed agricultural machinery, their quality improving and product damage reducing, as well as work complexity with coinciding terms, streamlining and rhythmicity of processes were formulated. Taking into account the system approach, the imbalance between the agro-industrial complex and management forms was reflected in the weak interrelation of their interests with state interests, which also affects the cost price of production. The negative aspects of the machine system for the mechanization of field crop cultivation were revealed. A special effect should be expected from the proposed combination of technological operations in one pass of the machine across the field due to full-scale adaptations to machines, the ratio of the park of caterpillar and wheel tractors and the work complexity. On the basis of these studies, proposals for traumatization reducing of grain by harvesting equipment and the cost of crop losses from trauma, as well as the regularities of the area of damage to grain from grain vitality have been substantiated. The reasons of production cost price increase are connected with attracting investment issues and managing innovative activities of introducing priority means of mechanization (concessional lending, subsidies, etc.)
The article is devoted to increasing beekeeping’s earning capacity with rigging and automation of technological processes. Winter is the most complicated and critical period in beekeeping. It influences on further productivity of bee colony. Winter period has specificity – bees are gathering in winter cluster and sustaining temperature in 24…32 °С range inside. This temperature is depending on fluctuation of outside air temperature. For passing winter without complication electric heating is used. Cluster geometry in winter is changing constantly and for optimal regime of electric heating we need to take it into account. Additionally, bees’ activity changing beehive’s microclimate and it’s important to know when beehive’s microclimate adaptive control system is developed. Conducted researches allow us to get basic equations which characterizes microclimate with taking into account of winter cluster’s variable geometry. The equations establish linkage basic parameters of beehive, winter cluster, internal air between outdoor air. Simulation results may be used for adaptive heating control system programming. Additionally, it may be used in special-purpose software for beehive’s microclimate simulation
