The aim of the study is to determine the parameters of the Archimedes spiral to construct the geometry of the disc of the shredder of long-stemmed feeds. The article describes the sequence of constructing the curved portion of the geometry of the disc of the shredder of long-stemmed feeds, based on Archimedes spiral. Criteria for building the disk on the second and subsequent turns of the spiral of Archimedes and obtained the dependence of disk diameter from the size of its protrusions. The conditions of Archimedes spiral construction depending on the number of disk protrusions are determined
The aim of the research is analytical determination of
the middle speed of the corn seeds on the flat vibrating
sieve of finite width. The object of the study is the
process of sorting of seeds of corn on the flat vibrating
sieve. The mathematical modeling of the motion of the
separated layer of the cereal mixture on the sieve is
conditioned by the necessity of intensification of
division of grain-growing materials on a flat sieve.
Despite the significant progress in the development of
mathematical models of the motion of a mixture on
vibrated sieve, their further refinement remains an
actual task. In particular, in calculation practice, theory
in which the width of the flat sieve is considered
infinite is used, i.e. the impact on the process of the
moving frame of the sieve bed is not taken into
account. In connection with absence of estimations of
the error brought in by this assumption, the necessity
to develop a theory of the movement of the mixture on
a sieve of the finite width appeared. For the analysis,
the following assumptions were accepted: first, the
corn seeds were considered as balls of different
diameter, second – the layer of grain on a sieve was
considered as heterogeneous viscid liquid. Based on
undertaken study it is set that most rational for the
achievement of the put aim is application of method of
Bubnov-Galerkin. As a result of undertaken research
analytical dependences are received for the calculation
of flowrate of grain mixture on the vibrational sieve of
the final width taking into account separation of the
mixture into factions
