We have provided technical solutions to improve performance
of technological systems for the preparation
of solutions and concrete based on the use of screw
rotors in the form of drums with helix lines formed on
the perimeter as interconnect lines of his spiral surfaces.
We discuss the six varieties of devices and installations
for mixing, including concrete mixers, reels
which are of a complicated geometric body formed by
helical surfaces with variable or constant pitch and
which creates screw lines in the places of their connection.
In the form of screw drums, they may be conical,
concave, convex, cylindrical. The experimental test
was conducted on the concrete mixer drums, which are
arranged one in the other. The implementation of the
mixer in the form of coaxially edited two barrels provides
not only a reduction in size in length, but a significant
reduction in energy consumption due to the
use of heat, released during the activation process of
inert heating of the concrete mix as when re-mixing
and concrete mix when mixing it with water and transportation.
The drums of such systems is made of flat
elements with the formation of the helical lines discretely
spaced around the perimeter of different pitch
and with different numbers directed towards each other
helical surfaces. In the process of transporting the
components of concrete in the internal screw drum
there is active mixture of sand, gravel and cement.
Thus, there is not only the destruction of lumpy, sticky
components of the raw materials, but also active uniform
distribution of particles of cement, sand and
gravel into a homogenous mass. The implementation
of the proposed technology and equipment ensures not
only reduction of the dimensions of the mixer length,
but also improving the quality of finished products, as
well as potential cement savings of 3-5%
The article presents research results of a corn harvester
device for corn cobs separation from the stalks,
constructed as a separate picker. Each picker unit
consists of three pairs of flat conveying belts arranged
in parallel to vertical planes, namely an upper pair of
conveying belts, the lower pair of conveying belts and
fixed to corn harvester sweep frame, kinematically is
not connected to other mechanisms and is provided
with electric power with the possibility of adjusting
the width of the aisle and the rapid replacement of the
failed module with a spare unit in the field repairs.
Picker module provides simultaneous rotation of corn
ear on its axis and motion relative to the stem that
reduces corn cobs defect and energy consumption for
separating cob from stalk. The method of calculation
of the basic design parameters of the picker module is
developed
A number of small-sized machines for division of loose
materials on the basis of screw drums created with use
of engineering geometry and computer graphics
methods, in particular of the engineering geometry
section: curves and surfaces. In these machines, unlike
the known ones, the effect of the movement of bulks on
the curvilinear surfaces of screw reels with imposing of
low-frequency fluctuations from the vibrator on this
main movement is used. Such addition of two
movements does not only increase productivity, but also
provides self-cleaning of the sifting surfaces of screw
drums. The standard machine’s schemes are presented
with use of low-frequency fluctuations on the basis of
the screw drums made of several screw punched strips
with smooth screw lines on perimeter and also of screw
drums of only one of punched strips with various form of
cross section of the sifting surface
In complex multiparameter technical systems there are
numerous and varied physical processes which, on the
one hand, have a significant impact on the
performance of those systems, and on the other hand, it
is extremely difficult amenable to description in the
form of meaningful analytical models based on
equations, because these models must take into
account the specific features of the systems. As a
consequence, the development of conceptual analytical
models is a "hand-made work" and it is associated with
a large number of simplifying assumptions that reduce
their versatility and reliability. But there is also another
principle of modeling: the construction of
phenomenological information models, i.e. models that
do not have analytical forms of representation that
describes the simulated system superficially as a
"black box". Such models can be built directly based
on empirical data and with the appropriate software it
can be a standard technology much faster and much
less time consuming than developing meaningful
analytical models. On the other hand, the
phenomenological information model can be sufficient
to determine the rational design features and
parameters of the modes of operation of complex
technical systems. Besides, such phenomenological
models can be viewed as the first stage in the
development of meaningful analytical models. It is
proposed to use a new universal innovative method of
artificial intelligence for creating phenomenological
models of complex technical systems: automated
system-cognitive analysis (ASC-analysis) and its
programmatic Toolkit which is a universal cognitive
analytical system called "Eidos". In the system of
"Eidos" we have implemented a software interface that
provides direct input into the system large amounts of
empirical data from an Excel file. The system of
"Eidos" can directly (based on empirical
(experimental) data) calculate how much information about the results of the technical systems is contained
in the facts of possessing certain specific structural
elements and certain values of the parameters modes
of its work. On this basis, the system provides
research-based and appropriate recommendations for
the rational choice of design features and parameters
of the operation modes of the simulated system
In this article the authors have proposed a process and arrangement for recycling in the poultry farms of the Krasnodar region of chicken manure and release of mineral fertilizers, аs well as the analysis of existing Russian technologies and devices for drying chicken manure. The study proposed a technology and apparatus for drying chicken manure to not only provide a significant deal of capital investments, but also cut energy costs by the proposed method and apparatus, as well as improving the quality of the finished product (chicken manure). In the method of drying chicken droppings produced removing mechanical impurities, mixing, drying and grinding of the hot gases, wherein the starting slurry is transported in a horizontal direction opposite to the flow direction of the hot gases while performing a gradual heating it with simultaneous comminution and mixing, and then after reaching the zone of maximum temperatures for each of the size fractions of the suspension is achieved by turning its direction on 180ºÐ¡ and then transported in a direction coinciding with the direction of flow of the hot gases by carrying out the gradual cooling of the heat transfer starting product. We have also presented norms of dry chicken manure application under agricultural crops in the Krasnodar region
The article examines the teaching descriptive geometry and engineering graphics on Faculty of Civil Engineering, higher-motivation of students to obtain needed competence to adopt competently compensation-drawings. The article describes the basic methods of conducting classes on the subject "Descriptive Geometry and Engineering Graphics" for students enrolled in the specialty 08.05.01 "Construction of unique buildings and structures." For lectures and laboratory classes in the department of descriptive geometry and graphics were developed multimedia courses with animation for all studied subjects, educational presentations that reveal the specifics of the discipline into account peculiarities of the educational process of learning in the Kuban State Agricultural university. Multimedia courses using enables us to model a situation that forces students to analyze, compare the solves of the task. Students develop an algorithmic way of thinking, formed the ability to think and act optimally variability. The use of multimedia development at the Department of Descriptive Geometry and Graphics showed an increase of performance results compared to the previous years of employment without presentation. It indicates that the use of multimedia lectures and laboratory exercises improves the efficiency and quality of education, as well as gives an opportunity to a greater extent to explain the learning material for students
