В работе приводится актуальность альтернативных источников энергии, место среди них ветроэнергетики. Дано краткое описание существующих ветродвигателей и конструктивные особенности волновых ветродвигателей. Представлены примеры использования ветродвигателей такого типа для прямого привода рабочих органов сельскохозяйственных машин, в том числе в линейных генераторах, в компрессорах тепловых насосов, в вентиляционных установках. Описаны их технологические преимущества.

The problem of separation of seed mixtures of crops, which are difficult to separate. It is shown that the separation of such mixtures the most efficiently on machines which process is based on the simultaneous use of several signs of separation. The analysis of such technical means separation allowed us to offer the most suitable method of separation of seed mixtures, which are difficult to separate. As a result of research of the design mechatronic vibration machine, which tests have shown high efficiency.
BY SIMPLIFYING OF THE EQUATIONS OF DYNAMICS OF BUBBLE FLUIDIZED OF GRAIN MIXTURE ON THE STRUCTURAL THREE-DIMENSIONAL VIBROSIEVEpg(s) 9-13
The article made some simplifying the equations of dynamics of bubble fluidized grain mixtures on vibrosieves that will determine their decision.
MECHANIZED PROTECTION OF FRUIT PLANTINGS FROM FROSTS BY INSTALLING THE THERMAL INSULATION CURTAINS MATERIALSpg(s) 14-16
This article propose a method and means of mechanization for the protection of the generative organs of fruit plantations from radiation frost by forming insulating curtains, consisting of both heated and humidified air, which makes it possible to protect future crops through development of non-critical temperatures.
Existing technologies postharvest treatment of small seeded crops mixtures because of the inability of the department are various kinds of trauma, as well as biologically inferior seeds without embryos should be improved. To intensify the process of separation can process further purification using elektrofryktsiynyh and pnevmoelektroseparatoriv, which as an additional working body uses high voltage electric field.
Due to its selective action on the complete seed and seed embryo without damage or smears unable to completely separate one from another. This is confirmed by experimental data separation elektrokoronniy winter rape on a hill and perennial grasses in the channel pnevmoelektroseparatora. They show that the content of low-quality seeds in vidseparovanomu material decreased from 21…26% to 2..4%, indicating a significant increase of sown seed traits studied cultures.
This article outlines promising methods to improve the performance and quality of grain combines by harvesting only ears as part of the harvest. The various types of earstripping machines, which are investigated in Kazakhstan. Also remaining standing straw is a good means of accumulating moisture on the soil and resistance to wind erosion.
