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
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
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 innovative technologies and developed methods and devices for drying chicken manure. Ways of their optimization on the basis of screw aggregates and a calculation technique for introduction in production are offered. The results of a long-term research into the search for and development of innovative technologies for the construction of a methodology for calculating not only a device for drying chicken manure with subsequent introduction into production, but also a device for drying bulk materials of agricultural purpose are shown. An example of thermal calculation and selection of the parameters of a drying device is shown on the basis of screw aggregates
The article presents the results of the research on modeling of working bodies of agricultural equipment by methods of engineering geometry and computer graphics. The design and the principle of operation of the equipment on the basis of working bodies in the form of screw drums is shown on the example of a device for the preparation of concentrated feed
The article considers manufacturing techniques and assembling screw propellers of transport vehicles for rice and fish farms. The increase in technological capabilities, reliability and carrying capacity of transport vehicles is achieved by making the propeller screw, with the possibility of its rotation. We called such propellers screw propellers, since along their perimeter along the entire length, multiple-curved curved surfaces are formed in the form of helical grooves of various configurations, sizes and shapes. The spatial form of the screw propellers is made with screw surfaces in the form of helical grooves, which ensures that the transport machines for rice and fish farms are conveyed on land, on water, through swampy and difficult terrain at a sufficiently high speed. As a result of the work performed, not only the designs of screw propellers and their classification were proposed, in which there is a general principle that allows the development of still unknown structures of propellers, but also their manufacturing techniques. The design of screw propellers was performed using the KOMPAS-3D software package using descriptive geometry and engineering graphics
