CHALLENGES AND TECHNICAL SOLUTIONS OF USING HIGH-PERFORMANCE TRANSPORT OF AGRICULTURAL MACHINERY

abstract 1141510073 issue 114 pp. 952 – 977 30.12.2015 ru 993
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

MODERN QUESTIONS OF POTATO HARVESTING EQUIPMENT PERFECTION

abstract 1141510075 issue 114 pp. 988 – 1003 30.12.2015 ru 927
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

NEW TECHNICAL SOLUTIONS FOR A SEPARATION OF THE ORGANS OF POTATO MACHINERY

abstract 1241610018 issue 124 pp. 346 – 365 30.12.2016 ru 605
One of the promising directions of development of agriculture of the Russian Federation is to increase the production, improve the quality and decrease the cost of potato cultivation. Annual cleaning is one of the most intense and costly in transport and technological processes. Potatoes - blending high culture and very picky about cleaning. The highest yields and income from potato production get where embedded technology to optimize energy and labor costs. The main (though not only) the special technical means used during machine harvesting potatoes, are potato harvesters. The main problem when cleaning is a problem of balancing conflicting requirements to the process and possibilities of agricultural machinery. Including increasing the purity of the tubers in the container with one hand, minimization of losses and damages of tubers on the other hand, when the performance of equipment. In this article we propose a circuit-design solution separating the working body of the potato harvester that allow for cleaning to significantly reduce the amount of traumatized potatoes in the process of separating soil and vegetable impurities, creating the preconditions for the elimination of damage to the tubers on the hard side of the working bodies of harvesting machines. Informed choice and timely use of plug-in modules (separating working bodies) in modern potato harvesting machines at work in specific climatic conditions allows them to fully match the list of regulated agronomic requirements. Thus, the creation of new science-based technical solutions for a separation of the organs of potato harvesters is an actual scientific-technical task, which makes a significant contribution to the development of the country

RESEARCH OF MODERNIZED BD-4M HAULM SHREDDER WITH ARTICULATED KNIVES

abstract 1281704012 issue 128 pp. 200 – 213 28.04.2017 ru 610
In the general complex of mechanized works when growing potatoes, potato harvesting is one of the main operations. The efficiency of potatoes growing at the farm largely depends on harvest quality and crop retrieval. When harvesting potatoes with potato harvesters their productivity largely depends on the state of potato haulm. In a case of evolved and laid haulm the harvesting machines productivity falls sharply due to working organs clogging and in some cases their work is not possible at all. Therefore, to facilitate the work of potato harvesters it is necessary to remove potato haulm before harvesting. But the process of haulm removing is very laborious, including several operations, such as mowing, raking and transportation, each of which is performed by a separate machine. The appearance of domestically made rotary-type machines like KIR-1.5, UBD-3 and BD-4 at the end of 1950-1960 made it possible to mechanize the harvesting process of potato haulm. But it was noticed in the operation that rotor machines have a number of drawbacks caused by imperfections in the rotor design, its kinematic regimes, lack of balance and some others. Therefore, studies aimed at improving the design of rotary-type machines seem to be very important. To achieve this goal some theoretical and experimental studies and lab and field tests of the modernized four-row shredder have been carried out. When studying methods of mathematical analysis and elements of classical mechanics were used. Some modern methods were applied in the lab and field tests. The modernized haulm shredder BD-4 was tested at JSC “Avangard” in Ryazan district
