In agriculture the issue of enhancing the
efficiency of operation of internal combustion
engines (ICE), reducing the costs of
maintenance (TO) and repairing (TP) fuel
supply apparatus (TA) using the improvement
of methods and means of diagnosis is a topical
in connection with the aging rolling stock
farming and lack of investment. Analysis of the
known TA diesel engine vehicles systems
showed that the most widespread system is the
divided type with multiplunger high pressure
fuel pump (fuel pump), while the methods of its
diagnosing are laborious, they require partial
disassembly and have insufficient accuracy.
The mathematical models that characterize the
work of a high-pressure fuel pump (fuel pump)
use a large number of parameters that
significantly affect the quality of dynamics of
the change of pressure values of diesel fuel.
However, in the materials of previously
published articles there were no issues
considered assessing the extent of the
quantitative impact, performance and features
change in the sensitivity settings of the
mathematical models on the simulation results,
there are no recommendations on the degree of
sensitivity and importance of each of the
parameters. For a more accurate diagnosis of
the fuel supply apparatus of a diesel engine it is
advisable to use several methods of diagnosing.
The article substantiates development of a
mathematical model of a high-pressure fuel
pump based on the analysis of modern methods
of diagnosing of fuel equipment for autotractor
diesel engines
The article presents a technical diagnostics of a car as a complex of goals and tasks connected with
trouble-shooting of mechanisms and systems in
order to eliminate them. We have considered the
stages of computer diagnostics of different
automobile systems such as diagnosing the engine,
the brake system, steering and suspension. We have
analyzed their components, the ways of troubleshooting
and elimination recommendations. The
article presents the main troubles transferred from
the electronic control unit. The article also presents
the stages of diagnosing the engine including
external examination, listening to abnormal noises,
checking the operating fluids and the engine
management system, diagnosing the basic engine
systems and checking the cylinders being filled.
The article contains the list of main troubles and
their reasons. One can also see diagnosing the brake
system, its defects and remedies. The article
presents diagnostics and repair of the suspender and
graphics describing the check of the dismantled
shock strut at the stand and tests of the shock strut
without being dismantled. We have analyzed
computer diagnostics and the problems it solves
The role of transport in agricultural production
is significant. It is the connecting link in the
technological chain of the agro-industrial
complex (of the APC). On-farm transport in the
APC together with cars and tractor transport are
widely used. The rationality of the use of
wheeled tractors for farm transport substantiates
the possibility of their movement on asphalt and
on dirt roads. The specific gravity of the tractor
transport in the domestic agriculture is 22-27%
of the total volume of transport and 50-60% of
the volume of farm traffic. A high level of use of tractor transport has been observed in the
countries of Western Europe and the USA. In
the farms of leading countries of Western
Europe (Germany, Italy, France, etc.) about 70-
90% on-farm transport of agricultural goods is
done by tractor transport. Tractor transport in a
live environment is running on roads with
varying terrain, a wavy profile cover, on soils
with different hardness and humidity. When
driving vehicles at high speeds, the trailer is
wobbling from side to side, constantly
accompanying tractor transport during its
operation. As a result, it is bad for propulsion,
transmission, and it deteriorates the dynamic
performance properties of equipment, working
conditions of the operator. To reduce the
amplitude of oscillations of the trailer, the
operator is forced to work strenuously with the
steering wheel or to slow down the speed,
which in turn affects operator fatigue, as well as
the performance and maneuverability of the
vehicle. Thus, advanced technologies in
electronics, sensor technology and software will
determine the nature of agro-technical
innovations and will lead to increased
automation of business processes in crop
production with the aim to organize the work
more effectively, efficiently, accurately,
environmentally friendly and economically
feasible. When working with intelligent
technologies, understanding the development of
high-tech, precision engineering requires a
revision to the personnel policy and education
in agriculture, which should be based on the
relevant organization of farms and their proper
new type engineering solutions
We have presented the technological scheme of a dispersal device which allows to increase the efficiency of cleaning and disinfection of automotive vans with specialized solutions
Due to the deterioration of the ecological situation
in the world, population tends to eat organically
grown foods that are grown either without or with
minimal use of chemicals. The development of
agriculture in this direction leads ultimately to
organic agriculture. To improve the competitiveness of this direction, we need more
effective agricultural machines, especially in the
last phase of cultivation, namely at the stage of
harvesting. One of the most difficult scientific and
technical problems with the mechanical harvesting
of potatoes is not letting vegetable impurities and
tops to fall down in the hopper with the potato
tubers, which among other things will improve
operational efficiency technology. The article
reviewed the various methods for removing the
tops, as well as their advantages and disadvantages.
The article makes a conclusion about the need for
potato top separators in harvesting machines. We
have also considered a promising device for
removing haulm, a conveyor with flexible fingers
on the bars and the clamping beater. Тhe most
short-lived structural element of the device for
removing haulm, reducing reliability of the device,
is flexible fingers mounted on rods. We have
proposed to use polyurethane as a material for
manufacturing flexible fingers
The effectiveness of disinfection depends on used disinfecting materials for vans, their actions and technological parameters of the installation for applying disinfectants. Hot mist generators provide uniform distribution of particles of disinfectant solution inside the van for transportation of agricultural products. The parameters of the generator of hot mist affecting the quality of disinfection were investigated. Tests were conducted for the vans used to transport agricultural products. For studies we used the vans in operation, which transport farm animals (pigs) and had been disinfected before. Sampling for the research on contamination was performed with pre-prepared swabs. Factorial experiment was planned with using scheme #32, and as a result of significant factors in the univariate experiments we set a temperature of the aerosol disinfectant solution and the duration of surface treatment. As an optimization function we have chosen disinfection efficiency of bodies of vehicles carrying agricultural products. Comparing the results of the experiments on different groups of microorganisms we have found that the optimal mode of hot mist generator with a dispersing device are: the processing time of 1 m2 - 8.5 at the processing temperature - 65º C
High-strength steels are used to increase the reliability of potato harvesters. With the advent of new materials and new technologies in agricultural engineering, it is possible to significantly reduce the mass of working bodies, to reduce energy costs. The elastic system of the composite elevator bar, unbalanced by the impact of the component of the potato heap, is in oscillatory motion. An increase in the height of the fall, and hence the speed of collision with the bar of the component of the potato heap, determines the amount of deflection of the composite bar. During vibrations, in addition to static deformations, dynamic ones are added, depending on the magnitude of the impact force. It was established that a bar made of composite material should have the following parameters: elastic modulus E = 55000 MPa; the diameter of the composite bar d = 0,012 m
The mathematical model presented in this article is designed to assess the probability of occurrence probability of technological failure potato harvester according to the specific conditions and usage
Condition monitoring is a necessary element of the
transport and special machinery in agriculture. The
task of the control operations other than the
determination of the technical state of the object is to
determine the required amount of work, as well as
rational amount of collateral the repair of which could
be combined with the next maintenance. Based on the
results of processing of the information, we may
generate requests for service. In the conditions of
uncertainty of receipt of requests for servicing of
individual machines, estimated volumes and timing,
we have am appropriate development of applied
technique of justification of the number of diagnostic
posts for interactive control of a technical condition
of vehicles and special machinery in agriculture. The
presented methodology is based on probabilistic
methods, and allows the quick optimization of the
number of existing posts interactive diagnostics in the
enterprise, if necessary, translating the existing posts
in "standby" mode, or Vice versa, returning from a
reserve in "work" mode. The production and
technical base of the enterprise service based on the specific assumptions are considered as a system of
mass service (SMO), and the function of such a SMO
– as the process of mass service. The process of
queuing as applied to interactive diagnosis are
"Markov" processes "death and reproduction" with a
finite or countable number of States and continuous
time. To describe the states of the system we use the
system of the Kolmogorov equations for steady state
of "Markov" process. On their basis, we have
determined average queue length, time of stay orders
in the queue, number of busy channels and the
bandwidth of the CFR. Using the intensity of the
requests and the service time of a single application
for specific equipment, the article establishes the
efficiency of online diagnosis posts. The result of the
proposed applied methodology enables timely
decision-making about the need for reconstruction or
technical re-equipment of the company
Potato is cultivated in 130 countries on an area of over
18 million hectares; it annually gives more than 300
million tons of tubers. The share of the Russian
Federation accounts is about 11% ... 14% of total
production. The resulting potatoes consumed in food, animal feed, technical purposes, seed fund. According
to the Ministry of agriculture of Russia, the largest
number of potatoes in our country (89 %) is produced in
peasant farms and personal farms of citizens, the area of
cultivation of which make up about 2.7 million hectares.
At such farms for the harvest, they use mainly potatodiggers,
followed by selection of crops manually. The
use of diggers in small areas of planting is more costefficiently
in relation to the harvesting combine. In
addition, the parameters requested for ATT to damage
potatoes when harvesting with the diggers (3%) are
higher than during harvesting by combine harvester
(5%). As practice shows, for the use of cleaning units,
even under optimal harvesting conditions in the hopper
of the combine, there are soil and vegetable impurities.
There are many different devices intended to localize
the problem. Based on the foregoing, we can conclude
that it is necessary to pay considerable attention to the
quality of work of excavating working bodies, because
it affects the productivity of the functioning of the
whole machine. Currently, there are widespread potato
aggregates with the receiving part, equipped with side
disks, spaced along the edges of the plowshares. The
disks cut off the raised layer of soil from between the
rows. This entails improving the performance of the
potato harvester. The most efficient and economical
from the point of view of energy consumption, is the
work of passive disks with hooks. The quality of potato
harvesters depends on the design and performance of
excavating bodies. The proposed design solution for an
excavating body increases the productivity of harvesting
machines
