ABSTRACT: The differential equation, obtained as a result of the theoretical study
of the movement of the bare seed on the surface of the grate of the saw gin,
made it possible to determine the trajectory of the movement of the seed. The rib is one of the main working bodies of the
saw gin. It serves for the free passage of the saw blades through it into the
working chamber, for the withdrawal of the fiber caught on the saw teeth after
separating it from the seed. A number of studies have been carried out to
improve the working elements of the saw gin. The purpose of the research is to create the
possibility of timely withdrawal of bare seeds from the working chamber of the
saw gin by creating a concavity on the working surface of the grate. The use of the Euler equation for the movement of bare cotton seed along
the grate contour, taking into account its speed V, density ρ, pressure P, made
it possible to obtain a graph of seed distribution along the grate contour. An
experimental 30-saw gin was developed and manufactured, the research carried
out on it allowed to determine the rational parameters of new grates, which are
recommended for introduction into production. The dependence of the location of
the rectilinear part of the general contour on the shape of its convexity and
concavity is determined. Based on the above equations, using separate functions, we present the view of the grate profile in the coordinate system modeled on the MAPLE-17 program.
