Improvement is offered for working bodies’ forms in devices for preparation of forages by methods of engineering geometry and computer graphics. That opens not only great opportunities for intensification, increase in productivity and efficiency of the technological processes, but also opens ways for creation of small-sized devices for their realization. Constructive study of geometry of working bodies surface, allows us to give wavy movement to particles of forage and impart them the movement with bigger power consumption. In such installations forage particles components, meeting walls of working body, change their direction and, meeting other portions of particles of forage components, mix up. From loading to unloading, throughout the installations working body length, flexible and strong waves of forage particles components movement inside the working body are born. The conducted pilot studies have shown that as a result of working bodies’ forms improvement of devices for preparation of forages by methods of descriptive geometry such devices can be implemented in a variety of industries

The article presents the results of studying of prospects of use of the relative screw and combined drums in agro-industrial complex. The developed and approved classification of the relative screw and combined drums has been shown in expanded form. The kinds of the equipment on the basis of the relative screw and combined drums making a rotary motion in which the oscillating motion with a big amplitude, only at the expense of an original spatial form of their internal surfaces is reported to subjects of processing are presented. In such devices, there are no vibroactivators. Equipment samples in which the relative screw and combined drums aren't rotated are also presented. They are fixed elastically on the bed and are supplied with vibroactivators. During the operation of the vibroactivator, processing subjects in such cars, as a result of the circulating movement in the relative screw and combined drums in the planes, perpendicular axes of their symmetry, receive the additional movement from the walls of drums of various geometrical forms inclined to each other

Analytical research results of contact forces of interaction of concentrated forages components’ particles in their movement in relative screw drums are presented. It is shown that contact forces – the most difficult forces by their nature; result from stochastic (probable) collision of bulks particles and in particular of concentrated forages components’ particles. Therefore the main objective of this modeling – to describe the stochastic phenomena of the so-called conditional contacts of particles for which some assumptions are accepted, for example, in forcing of mass of concentrated forages components’ particles by the walls of the rotating relative screw drum in the radial direction there will simultaneously arise contacts caused by geometry of a screw drum, i.e. the property of its walls is pressure transfer in relation to the mass of particles in the direction of the modeled movement. Schemes of engagement of concentrated forages components’ particles contacting in the relative screw drum, the probable schedule of sliding speeds values change in their consecutive contacting, their density distribution are demonstrated

The article presents the experience of creation of the equipment on the basis of the relative screw and combined drums providing highly effective technological processes, because for such drums it is characteristic not only creation of fluctuations to processing subjects with an amplitude of movement of 15-1000 mm and more, but also the opportunity to operate oscillatory process, changing transport or technological effect. Therefore, works on creation of the equipment, for realization of such technological processes, are extremely important and actual for dehydration of manure, drying of chicken dung, and for preseeding processing of seed material. We present kinds of the equipment in which vibroactivators are absent. Equipment samples in which relative screw and combined drums aren't rotated are also presented. They are fixed elastically on a bed and are supplied with vibroactivators. In such devices during the operation of the vibroactivator, processing subjects as a result of the circulating movement in the relative screw and combined drums in the planes, perpendicular axes of their symmetry, receive the additional movement from the walls of drums of various geometrical forms inclined to each other

The article reveals a possibility of using equipment based on relative screw and combined drums for mixing of bulks. Change of relative positioning of flat elements of sidewalls of internal surfaces in relative screw drums allows operating the difficult and spatial movement of streams of bulks. In relative screw drums we have developed effective processes of mixing and sets of the equipment, which are characterized by that fact the difficult and spatial screw movement taking place in relative screw drums is dismembered on rather simple, in the kinematic relation, in the movements. The difficult and spatial screw movement with a big amplitude of 15-1000 mm and more, in the offered equipment constructions on the basis of relative screw or combined drums, is reported to bulks by elements of the relative screw or combined drums of various parameters and configurations which becomes complicated also screw lines on perimeter of a relative screw drum with various number of calling and the directions from each other or rounds of the springs fixed in the relative combined drums

In this article the authors have proposed a process and arrangement for recycling in the poultry farms of the Krasnodar region of chicken manure and release of mineral fertilizers, аs well as the analysis of existing Russian technologies and devices for drying chicken manure. The study proposed a technology and apparatus for drying chicken manure to not only provide a significant deal of capital investments, but also cut energy costs by the proposed method and apparatus, as well as improving the quality of the finished product (chicken manure). In the method of drying chicken droppings produced removing mechanical impurities, mixing, drying and grinding of the hot gases, wherein the starting slurry is transported in a horizontal direction opposite to the flow direction of the hot gases while performing a gradual heating it with simultaneous comminution and mixing, and then after reaching the zone of maximum temperatures for each of the size fractions of the suspension is achieved by turning its direction on 180ºÐ¡ and then transported in a direction coinciding with the direction of flow of the hot gases by carrying out the gradual cooling of the heat transfer starting product. We have also presented norms of dry chicken manure application under agricultural crops in the Krasnodar region

A number of small-sized machines for division of loose materials on the basis of screw drums created with use of engineering geometry and computer graphics methods, in particular of the engineering geometry section: curves and surfaces. In these machines, unlike the known ones, the effect of the movement of bulks on the curvilinear surfaces of screw reels with imposing of low-frequency fluctuations from the vibrator on this main movement is used. Such addition of two movements does not only increase productivity, but also provides self-cleaning of the sifting surfaces of screw drums. The standard machine’s schemes are presented with use of low-frequency fluctuations on the basis of the screw drums made of several screw punched strips with smooth screw lines on perimeter and also of screw drums of only one of punched strips with various form of cross section of the sifting surface

The authors have developed and manufactured a large number of different designs of relative helical drums for mixing animal feed. We have conducted 749 field experiments with the drums of the 10 different designs with different parameters modes of operation. In all experiments, we measured the quality of the feed mixture. However, directly based on empirical data, rational choice of design features and parameters of the operation modes of the reels is not possible. For this, you must first develop a model reflecting these empirical data. The construction of meaningful analytical models of different types of drums is a difficult and demanding scientific task, the complexity of which is due to the large variety and complexity of forms of drums and their mode of usage, a large number of diverse physical factors affecting the processes in the drum. As a consequence, the development of analytical models associated with a large number of simplifying assumptions that reduce their versatility and reliability. Therefore, it is important to search of a mathematical method and software tools provide a quick and simple for the user to identify and influence the design of the drum and the parameters of the operating modes on the quality of the feed mixture directly on the basis of empirical (experimental) data. The work proposes a solution to this problem with the use of a new universal innovative method of artificial intelligence: automated system-cognitive analysis (ASC-analysis) and its programmatic Toolkit – universal cognitive analytical system called "Eidos". In the system of "Eidos" we have implemented a software interface that provides direct input into the system large amounts of empirical data from Excel file. Created on their basis in the system of "Eidos" system-cognitive model allows the visual form to reflect the effect of the structure of the drum and the parameters of the operating modes on the quality of the resulting feed mixture and to develop on this basis the science-based and appropriate recommendations for the rational choice of design features and parameters of the modes relative to the screw drums. We have also given a numerical example

Results of engineering and scientific search of improvement of resource-saving machine technologies of finishing and cleanup processing of cars details, development of new camps and technologies are presented. The possibility of low-frequency fluctuations with big amplitude can be implemented due to assembling flat or curvilinear elements on external surfaces of the relative screw reel. The use of computer modeling enabled us to obtain a relative screw drum that provides not only giving movement to loading masses with a big fluctuations amplitude, but also compression of loading masses in the process of their motion from loading to unloading. In such machines increase in processing efficiency is reached not only due to achievement of great movement amplitudes values of the loading masses, but also at the cost of compression of loading masses in processing and intensity increase of their mixing. The scheme of the machine for continuous processing with mechanization of separation of details from working environments particles is provided. Results of researches of quality and surfaces micro hardness change processed in the offered machines designs show that details processing time makes 3-6 min
