Description
The article proposes the updated model of the influence of logs length onto a size of wooden chips produced with the use of a disk chipper. This article focuses on the fact that the length of any of the logs in the process of chipping is reduced. For this reason at the final stage of chipping, any of the logs with a standard initial length of 1.2 m inevitably transform into short logs, for which the conditions of chipping are significantly different from the chipping conditions at the start of chipping. The task of accounting for these changes is reduced to finding a solution of the transcendental equation. The results of numerical simulation indicate a progressing decreasing trend in the bevel angle and increasing in the length of the particles of wood chips with decreasing of logs length. Adequacy of the modeling results confirmed by laboratory tests and production experiment. Measuring linear and angular dimensions of chip real particles showed that the particles of such length may be equal to 7 cm, which is 3.5 times larger than the standard length of 2 cm. The angle of the bevel of the cutting plane of the particle may be 14º, which is approximately three times less of standard value equal 39º- 43º. We also discuss the comparison with the approximate solution, which was published in 2012 year. The article can be useful for specialists of wood-preparatory cycle in the paper industry

UTILIZATION OF RICE STRAW BY CHOPPING AND SPLITTING WITH A POST-BLADE CYLINDER
DescriptionThe article focuses on the utilization of rice straw by chopping and splitting with a post-blade cylinder. The amount of rice production and rice straw in the Krasnodar region are specified in the article, as well as methods of utilization of non-grain part of rice harvest of rice, namely, burning in the field and use of rice straw as an organic fertilizer. The article describes a research on determination of the degree of rice straw humification under natural conditions at different parameters of its crushing and patching. According to the experimental results there was constructed a graph of the degree of rice straw humification by variants of the experiment. There was offered the projected constructive scheme of mobile trailer rice straw crusher from rolls in the article. The main results which were obtained to the present moment were shown in conclusions

THE DEVICE FOR STORING AGRICULTURAL MACHINERY IN PROTECTED FORM IN OUTDOOR AREAS
DescriptionThe carried out analysis studies the influence of various factors on the preservation of agricultural products and shows that it is largely determined by design features of machinery and technological methods of use. The efficiency of agricultural and mobile trailer machines has been forming by service and storage. Low quality of work associated with the storage of agricultural machines is conditioned by the fact that the lack of financial capacity of rural producers on acquisitions of modern equipment and materials for carrying out the preparation of for long storage, and also the construction of modern agricultural machinery storage sites. If a car can be fully or partially protected from the solar radiation, rain and snow, simply by removing it in the room, under a canopy or covered with a protective cover, by the formation of condensation on the surface of the machine units and parts these ways to protect do not work. Enhancing of preservation of agricultural machinery is possible when protecting the vehicles from atmospheric precipitation in the form of snow and rain, influence of solar radiation, and also due to the change heat exchange processes of the machine with the environment that prevents the formation of moisture condensate on its surface, ie. we have to create conditions when cooling rate at which the surface of the machine would be equal to or less the rate of cooling air. This is possible through the use of a special design, which would prevent the intense heat radiation of the machine into the environment, ie, would reflect heat rays using its surface and return them to its surface and thus fulfill the role of the heat shield

Description
In this paper, we investigate the stability dependence of integrated information content on the distance from the celestial bodies of the Solar System, with the change in the extensive pre-cases as the total number of cases, the implementation of the choice of social categories, and the number of categories. It was found that for each celestial body, there is a set of categories in which the depend-dependence of the integrated information content of the distance is determined with the greatest certainty. A model of the gravitational sensitivity, based on the mechanism of hormonal regulation of heat and pressure is discussed.
