The tasks set in "The strategy of engine and technological modernization of agriculture until 2020" provide growth of labor productivity by 3–4 times. In our article, we have attempted to concretize in a zone sectional view the direction action for successful engine and technological modernization for the purpose of implementation of such strategically important point. Radical modernization of system of vehicles for complex mechanization of field husbandry based on the domestic equipment in relation to natural and technological conditions of the Krasnodar region is offered. Realization of system of transport is supposed with use of the equipment of the fourth generation, but in 2020 the equipment of the fifth generation and innovative processing methods for production of grain crops has to be realized. It is noted that the solution of such task without the state participation is impossible. The fundamental principles of improvement of system of vehicles for field husbandry and engine technologies are offered. The main of them is a new system of mobile power, new highly productive motorless grain - beetroot-, forage harvesters, new multipurpose units with the offered devices for combination of the technological operations changing labor-intensive technologies radically. We offer replacement of heavy tractors, self-propelled combines; cutting-down of the nomenclature of the equipment at the expense of multipurpose units, main application of fertilizers along with processing of the soil, drop of sealing of the soil and its dispersion. The offered technical re-equipment of branch will provide precision performance of operations, increase in labor productivity and economy of resources
The article proves and develops the idea, the imple-mentation of which would significantly reduce the effort required to develop the educational-methodical complexes, simplify their signing and approval of the various officials and increase their quality, make the work of the developers of CBM more creative, releas-ing it from technical and routine moments
In the article, we have presented the theoretical foundations of wear, cancellation and disposal of agricultural machinery. We have also considered the methods of wear equipment, documentation cancellation technology and the problem of utilization of technology
An analysis of patented in Russia and abroad methods for
providing preservation of plant products, particularly apples
and pears, was carried out in the article. The patent search
was made for the period from 1995 to 2015 in the databases
of patent offices of the United States of America, Japan and
European patent organization. The patented methods,
realization of which allows increasing of storage life of
agricultural products by means of using different kinds of
electromagnetic radiation, regulating the content of gaseous
medium in the storage, treating with chemical substances,
inhibiting the microbiological processes, creating hermetic
storing conditions, were systematized.
The realized research allowed drawing a conclusion on the
relevance of work in the field of search for new methods for
providing stable quality of fruits in the process of storing,
particularly with the use of electromagnetic fields of very
low frequency
The article analyzes the ways of ensuring a stable
quality of fruit in the process of storage. The patented
methods of storage, realization of which allows
increasing of storage life of agricultural products by
means of using low temperatures, regulating the content
of gaseous medium in the storage, creating hermetic
storing conditions, treating with chemical substances,
using biopreparations, were systematized. The analysis
of literature sources and patent information has show
that the development of methods for storing plant raw
materials with using biopreparations is up-to-date
The article analyzes the ways of ensuring a stable
quality of vegetable raw materials in the process of
storage and use of biopreparations patented in Russia
and abroad. The search was conducted in the period
from 1995 to 2015 on the databases of the patent
agencies of the Russian Federation, the United States,
Japan and the European Patent Organization. We have
systematized the patented methods, the
implementation of which can increase the shelf life of
vegetable raw materials. The study led to the
conclusion of the usefulness of developing innovative
ways of ensuring a stable quality of vegetable raw
materials in the process of storage using
biopreparations
The article is devoted to justification of application of an electroozonizer for sterilization of vegetable substrata and fodder grain in the course of biotechnological production
The article deals with the basic methods of stabilizing voltage generators for small hydroelectric power plants. It shows a block diagram of the implementation and analysis of the characteristics of the work; it reveals the advantages and disadvantages. The authors explain the features of the work of the functional circuits voltage regulators with discrete ballast, with phase control and management of the load current. It is shown, that to improve the performance of small hydroelectric power plants considerably we have to use contactless generators in their construction: asynchronous generators with capacitive excitation and synchronous generators with permanent magnets. The functional scheme of the voltage regulator, the construction of which has an additional field winding, simplifies the system voltage stabilization of the synchronous generator with permanent magnets, as well as a functional scheme of an asynchronous generator voltage regulator, made using step-up transformers, which significantly reduces the weight of the capacitors providing excitation of the generator and compensation of reactive power load. We have discussed the methods and devices for stabilization of voltage generators which will improve the effectiveness of pre-design work on the creation of new devices of stabilization of parameters of electric power generators for small hydroelectric power plants with improved operational and technical specifications
In this article we have investigated ways to preserve the quality of horticultural products during transportation and loading works for the intrafarm transportations
The article deals with studying the ways of optimizing
the amount of chemical additives in the wood-concrete
material, i.e. arbolite, which contains foamed
polystyrene gravel aggregate. To make arbolite
honeycombed structure more conglomerated a nonreactive
aggregate, i.e. hogged chips, has been partially
replaced with foamed polystyrene gravel aggregate
which has a mean particle size equal to a concrete
pocket size. The article also deals with various
additives to be used, taking into account the nonreactive
aggregate type and its quality, the composite
density and its reinforcement level. All chemical
additives have been chosen to make the initial material
more porous, to produce a film covering the aggregate
surface and to speed up the process of concrete
hardening. To solve to above problems a series of
experiments was carried out, the latter studied various
combinations of factors changing at certain levels. The
results of studying the foamed polystyrene gravel
aggregate influence on the arbolite structure and its
characteristics were used to make a choice of the
arbolite composition. The main criterion of the optimal
amount of chemical additives has been considered the
arbolite strength. The experimental data processing has
resulted in the finite regression model which describes
the chemical additive amount influence on the arbolite
strength. The tables in the article show the levels of
technological factors varying and the matrix of
planning the experiments to be carried out in order to
optimize the chemical additive amount. As a result of
the research accomplished the optimal amount of
chemical additives has been determined which enables
to produce the arbolite with some foamed polystyrene
gravel aggregate in its composition
