BSTRACT
The article presents the results of analytical and experimental determination of the required size of the
hopper of the seed seed hopper-dispenser. It was determined that the necessary size of the bunker-doser
hopper is directly related to its productivity and the residual hairiness of the seed. Taking into account that
the recommended productivity of hairy seed preparation workshops is equal to 3 t/h, the rational size of
the hopper was determined. It was concluded that the seed should be from 8.57 to 11.14 m 3 depending
on the residual hairiness of the seed.

Increasing competition in the world's cotton
markets, growing and zoning new selection
varieties of cotton in cotton-growing countries,
improving the consumer characteristics of the
product and reducing production costs due to the
development of seed preparation technologies
are increasing the urgency of reducing wholesale
prices. Accordingly, in order to improve the
quality of seed cotton seed in the world market
and reduce its cost, to increase its fertility through
targeted treatment, to reduce seed consumption,
to increase disease resistance, at all stages of seed
seed production, as well as in the processes of
seed collection and transfer in the specified
standard, factors that have a negative effect on
product quality identifying and eliminating them,
creating resource-efficient technologies that
reduce product production costs remain one of
the important tasks 1 .
Increasing the productivity of cotton, which is one
of the main crops in our republic, depends on the
quality of seed preparation. With the increase in
the demand for the quality indicators of the seeds,
it is necessary to carry out their sorting and
treatment works perfectly. Bunker-doser devices
were installed in order to improve the
performance of the technological equipment in
the technological system of seed preparation, as
well as to improve the quality indicators of the
sorting and treatment processes. Scientific
research work was carried out at the joint-stock
company . "Cotton Industry Scientific Center" to
determine the main parameters of the hopper-
doser, which serves to dose transfer of hairy seed
at a certain specified working fertility.
The following empirical expression of the slope of
the bunker walls by I.I. Novitsky was used in this
work.

recommended to be equal to 8.63 m 3.
Based on the analysis of the scientific research
conducted at the joint-stock company . "Cotton
Industry Scientific Center" it can be said that the
experiments on the justification of the size of the
bunker were not conducted enough 2 .
The main part
Based on studies of the performance of existing
seed processing plants, we determined that the
residual hairiness of seed delivered to existing
seed processing plants varied from 9.0 to 11.0
percent. It is more correct to select the size of the
hopper-dispenser hopper depending on the
residual hairiness of the seed, because it is self-
evident that the higher the residual hairiness of
the seed, the more volume it occupies.
During the experiments, we determined the
coefficient of residual hairiness of the seed seed
with K and assumed K=1 at 9.0 percent hairiness.
The rational size of the hopper of the hopper-
doser can be determined from the following
expression, taking into account its performance

performance (at values of K-coefficient equal to 1.0, 1.1, 1.2 and 1.3).
After determining that the residual hairiness
coefficient of the seed can vary from 1.0 to 1.3,
using the above expression, we made a graph that
determines the required size of the hopper
depending on its performance (Fig. 1).
Since the operation of the hopper-doser is
continuous, we assumed that t0=1. Because the
times of filling the hopper with seed and emptying
the seed are equal to each other.
C
ONCLUSION
From Figure 1, it can be concluded that the
required size of the hopper-doser hopper is
directly related to its productivity and the
residual hairiness coefficient (K) of the seed.
Taking into account that the recommended
productivity of hairy seed preparation workshops
is equal to 3 t/h, it can be deduced from the above
