IMPROVING THE EFFICIENCY OF WEAR-RESISTANT COATINGS ON CUTTING BLADES UNIVERSAL GRINDERS

abstract 0851301019 issue 85 pp. 224 – 244 28.01.2013 ru 1341
In the article, it is established that in the market conditions of economic recession of repair production, the traditional technological decisions focused on mass and business lot type, have lost the practical importance. Increase of the efficiency of drawing of wearproof coverings with the electropulse way is based on the use of technological possibilities of the way and the principles of technical self-sufficiency of small repair shops. For that, the combined way of processing, replacing use of the traditional technological equipment, with obtaining quality comparable to the existing technologies has been developed

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

abstract 1281704012 issue 128 pp. 200 – 213 28.04.2017 ru 354
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
