The sowing unit is one of the most important working
bodies of the drill. It is used to select from the total mass of a certain
number of seeds and the formation of their output flow with the specified
parameters. Therefore, the advantages and disadvantages of seeders, in
terms of the quality of seed distribution in a row and general in the sown
field, are mainly determined by the work of sowing machines. The
research was carried out to develop a model of random packing of seeds
of small-seeded crops in the tank of the sowing apparatus of the selection
drill. The research was conducted based on numerical simulation in the
software package of the CAE-system Simcenter STAR-CCM +. Because
of research, the mathematical model of casual packing of seeds of small-seeded cultures in the capacity of the sowing device of a selection seeder
is developed that allowed defining the equation of regression of its density
from the effective diameter of seeds and coefficient of variation of this
diameter. As a result of research of process of work of the batcher of the
sowing device of a selection seeder regularity of change of its throughput
from an angle of inclination of a gate, type of a form of executions
(triangle, semicircle, rectangle) in the form of a polynomial of the third
degree are received. It is established that the choice of the triangular shape
of the dispenser allows for ensuring the highest accuracy of seed dosing.
