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
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
Original screw designs of buildings and columns are
offered. Frameworks of these buildings and columns
are the bearing elements and means of external and
internal decoration of buildings and constructions.
Originality of such buildings and columns frameworks
is ensured by the fact that their design is decorated on
the outer surface with broken or smooth screw edges
and screw surfaces. Versatility of the offered screw
columns trunks designs, as well as the possibility of
performance of their left or right screwing allows
reaching certain symmetry or their repeatability in the
form of harmonious alternation of the bearing trunks
of screw columns and spaces between them. Giving to
numerous sides of trunks of screw columns of a certain
invoice, or their coloring in different colors, will contribute
even more to their expressiveness and beauty.
Durability and vibration resistance (including seismic)
of such trunks of screw columns at the same volumes
of construction materials, in comparison with round
and rectangular trunks is higher
The article presents results of research of rotary-screw
systems in relation to the creation of rotary kilns for
the annealing of-cuttings in the preparation of cement
clinker. Using the proposed design, in comparison
with known designs of similar purpose, it significantly
improves performance, reduces size and power consumption
through the use of rotary screw systems in
the form of screw rotors and drums made hollow with
sidewalls assembled from separate strips or plates of
different geometrical shapes with form inside the
screw breaks or smooth edges, screw surfaces and
screw grooves. It is shown that the housing of the rotary
kiln is expedient to produce helical surfaces whose
centers of curvature are located within the housing.
Using the proposed constructions rotary kiln during
the firing when preparing cement wedge can increase
the speed of rotation of the housing, furnaces 5-10
times due to changes in the rotary-screw systems increase
efficiency and reduce the size of furnaces
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%
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
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
The article presents results of design development and
calculation methodology for corn harvesters stalks
shearing mechanism constructed as a module with a
storage device. According to the number of
engagement rows, these modules are mounted on the
sweep frame of corn harvesters. All modules have the
ability to accumulate energy, the rotation of saws in
which at each time point does not depend on saws
rotation in other modules and they are not connected
with each other and with other mechanisms.
Constructive execution of corn stalks shearing
mechanism with accumulation device allows rapid
separation of each module from the frame of the corn
harvester in order to eliminate possible problems
(change of saw or the entire module assembly). The
methods of the energy storage calculation and electric
motor power selection for each module are presented
The article demonstrates a possibility of creation of a
corn harvester with a sweep frame mounted from
individual modules. Such corn harvesters include
modules for cutting stalks, snapping modules,
conveyor modules for turning, stacking and feeding
the stalks in the shredding unit, conveyor modules for
supplying corncobs to the cleaning device placed on
the sweep frame, leading and managing bridges,
power unit, as well as conveyor belt for cobs and
auger for discharging the crushed plant matter. The
technique for calculating the grinding module drive
was shown. The arrangement of the modules on the
corn harvester sweep frame was demonstrated. Corn
harvesting with the suggested module corn harvester
allows not only reducing combine metal consumption
and reducing corn ears injuring, but improving
maintainability as well
Analytical research results of contact forces of interaction of concentrated forages components’ particles in their movement in relative screw drums are presented. It is shown that contact forces – the most difficult forces by their nature; result from stochastic (probable) collision of bulks particles and in particular of concentrated forages components’ particles. Therefore the main objective of this modeling – to describe the stochastic phenomena of the so-called conditional contacts of particles for which some assumptions are accepted, for example, in forcing of mass of concentrated forages components’ particles by the walls of the rotating relative screw drum in the radial direction there will simultaneously arise contacts caused by geometry of a screw drum, i.e. the property of its walls is pressure transfer in relation to the mass of particles in the direction of the modeled movement. Schemes of engagement of concentrated forages components’ particles contacting in the relative screw drum, the probable schedule of sliding speeds values change in their consecutive contacting, their density distribution are demonstrated
