Potato has been and remains one of the five world's
most important crops. For nearly two hundred years
potato in Russia is the "second bread". This is one of
the so-called social products. Over the past 20 - 25
years of potato farming in our country, there have been
significant changes, both positive and negative. Today,
potatoes are grown in different soil and climatic
conditions in more than one hundred countries around
the world, including the desert oasis and beyond the
polar circle. Potato cultivation Center recently has
moved to Asia. In our time, the leaders of potato
production are China, Russia, India, the US and
Ukraine. Over the past few decades the number of
produced potatoes has increased by 41% and the area under potato planting only 9.5%. From the above data
it is clear that the world potato economy in recent
years has got significant changes, indicating that the
timeliness and relevance of the material in this article
is true
One of important features of development of modern society is special attention world the public to problems of rationality and efficiency of use of the existing energy resources, universal implementation of technologies of energy saving and search of renewable energy resources. Gradual depletion of world reserves of oil, increase in prices for traditional motor fuels, adverse ecological situation and other factors prove the relevance of more urgent use of the available resources and works promoting development of this direction. Deterioration in a global ecological environment requires adoption of more strict requirements imposed to the fuel used in an agro-industrial complex. According to the principle of cost accounting, each entity can rely only upon itself and consume only the resources it has. It is known that fuel costs constitute a considerable part in an expense structure of agricultural enterprises. In this case, the reduction in fuel consumption can be achieved through improved processes of fuel mixing and fuel processing (fuel dearomatization, ultrasonic treatment, magnetic, electrostatic and electromagnetic processing). Bench tests of a diesel engine equipped with an experimental device for ultrasonic treatment, showed good results, confirming the relevance of the use of such devices. Devices for processing are compact enough and consume little energy, while having a sufficiently high coefficient of performance. Having small size and relative simplicity of design that does not cause complex technical issues in production, these devices can be used on virtually any type of equipment that is used for the solution of agricultural problems. The purpose of this article is to evaluate the economy of the diesel fuel when ultrasonic treatment on the example of the motor transportation enterprise
This article discusses the results of the studies made by the faculty and the staff of Ryazan State Agrotechnological University named after P.A. Kostychev confirmed with RF patents
In the article we have analyzed the results of measurements of pressure of gases in the combustion chamber and the fuel pressure at the inlet injector diesel D-243 at a processing frequency (acoustic and electromagnetic) fuel 17 kHz
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
Material and technical resources form a large part of the
costs in agricultural production and determine the level
of intensity of agriculture, productivity and
competitiveness of the industry. The most important
role in agricultural production is played by transport
operation, from productivity and quality of which
directly depends the volume and the grade of final
products. More preferable is tractor transport,
particularly for on-farm transport, taking into account
the impact of navigation systems on the ground.
Continuous growth in the saturation of tractors carried
out around the world, improves the performance of
tractor transport aggregate by increasing their capacity and speed, either on the road or in the field. However, if
you increase the saturation of tractors, it encounters
problems related to the deterioration of the
controllability of the tractor and transport unit. The
reduced controllability leads to an increase of damage to
transported agricultural products owing to increased
oscillatory processes in the system of "road – trailer –
tractor – operator" when driving on-farm trails,
deteriorating the smoothness and braking properties.
Especially sharp these questions relate to transportation
of easy-to-damage agricultural products at farm
transportation. The feature of data traffic lies in the
sharp drop in grade products (products receive
numerous mechanical damages, deteriorating its quality,
and lose marketability and accordingly reduced its cost).
Influence on fruit and vegetable products of unfavorable
factors can lead not only to a dramatic loss of quality at
the time of transportation, but also reduce the resistance
during further storage. To solve the problems emerging
when increasing the saturation of tractors, we have
proposed devices, allowing reducing negative impact on
the production of elevated oscillatory processes, to
increase the permeability and straightness of movement
of tractor-transport unit
