PROSPECTS OF USE OF RELATIVE SCREW AND COMBINED REELS FOR MIXING BULKS
DescriptionThe 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

Description
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

Description
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

SMALL-SIZED MACHINES CREATION VIA ENGINEERING GEOMETRY AND COMPUTER GRAPHICS METHODS
DescriptionA 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
