Аннотация

Subjects of research: friablings of the combined unit and technological process carried out by them. Purpose of work: a substantiation the parameters of friablings of the combined unit for the minimal processing of ground ensuring high quality of ground at energy expense. Methods of research: the theoretical researches arc executed on the basis of the theoretical mechanics, theory of a wedge and maximum mathematics, and experimental researches - on standard methods with application of the developed experimental combined unit, method of mathematical planning of experiments, regressive analysis and tcnsomctcring. The obtained results and their novelty: on the basis of research of interaction with ground friablings of the combined unit substantiations the geometrical form of a working surface, the analytical dependences allowing todcfinc (determine) a angle of entry in ground, width and length, and also pulling resistance friablings arc deduced. Practical value: application of the combined unit supplied with friablings, with recommended form and parameters, operation expenses for 12,7 %. Degree of embed and economic effectivity: experimental samples of the combined unit (in 2007-2008) have undergone wide economic tests on fields of a farm «Ок suv» of Kurgantepa region of a fog Andizhan viloyat UzMEI plots in 2007-2008. The results of researches arc accepted oy ISC «BMKB-Agromash». and arc used in dcveloing of a design of the combined unit KA-1,8. The annual economic benefit of use of the developed unit makes 3208297 soums a machine. Fieid of application: agricultural mechanical engineering, agriculture.
