BSTRACT
In order to improve the equipment of harvesters, we need to have information about modern working
bodies for harvesting cotton grown for the textile industry, since new technological equipment is now
being imported into our country.

NTRODUCTION
To date, the design of mass-produced cotton
pickers (CP) has several shortcomings that limit
the productivity of CP, and reduce their reliability
and the quality of the harvested raw cotton. This
factor also hinders the increase in HUM exports to
countries with similar cotton cultivation practices
[1-4].
In particular, the controlled axle of a mass-
produced
cotton
picker
has
several
disadvantages. These are the underload of the
controlled
axle
(wheels),
insufficient
manoeuvrability, poor manoeuvrability, and
inefficient structural location in the structure.

All these factors have a negative impact on the
performance of the produced CP. The underload
of the steered axle leads to a deterioration in the
controllability of the steering wheels. As a result,
it is not possible to achieve the minimum turning
radius built into the CP design. This disadvantage
is also the reason for the low manoeuvrability of
the CP. The note leads to an increase in the size of
the turning lanes in the fields [6-11].
The discrepancy between the angles of rotation of
the inner and outer wheels of the axle causes low
controllability and, as a result, the machine
cannot confidently overcome bumps and
irrigation communications. When the wheels
leave ditches and various recesses, the CP rear
steered axle is overloaded. This leads to axle
failures in the field, which complicates
restoration work [12-16].

ETHODOLOGY
These problems are completely solvable, for their
solution it is necessary to develop mathematical
models and make the best technical solution for
the development of a controlled CP axis through
the use of information technology.
Based on the literature and patent research,
several technical solutions have been developed
for the design of the controlled axles of the cotton
picker. As a result of these studies, a preliminary
layout of a 3D model of a steerable bridge based
on the previously developed CP MX-1.8 was
carried out (Fig. 1).

In this regard, SKB "Tractor" carries out research
and development work on the development and
implementation of models, algorithms and
software tools for control and decision-making
that ensure the optimization of design
parameters and the design of the controlled CP
axis.

ESULTS AND DISCUSSION
Based on the conducted research, the following
conclusions and conclusions were made:
•
based on the analysis of existing HUM
structures and their comparative assessment,
a design for research was selected that most
fully meets the requirements of domestic
standards and has high agrotechnical and
technical and economic indicators;
•
the layouts of the mass-produced and
modernized CP steerable bridge are
considered and kinematic calculations of its
main structural components are made;
•
developed a mathematical model and
algorithm for optimal control of the
movement of the guide wheels of the cotton
picker MX-1.8;
•
A mathematical model of movement was
developed and the rolling conditions of the
MX-1.8 cotton picker were established;
•
A calculation for the static strength of the rear
axle beam of the MX-1.8 unit was carried out
under extreme types of loading (side sliding,
movement over bumps, an insurmountable
obstacle) considering two sections, based on
which the minimum allowable dimensions for
the design and manufacture of the beam were
established;
•
the calculation of the static strength of tapered
roller bearings was carried out, the results of
which showed that the safety factor of their
static strength is greater than the permissible
value; verification calculation of the total
resource of the rear wheel axle bearings
showed that the bearings do not have
sufficient durability;
•
the efficiency of the steering boosters was
checked and it was found that when the CP is
turned, the movement of the driven wheels in
the plane of rotation without slip is ensured,
and also two Ts-50 hydraulic cylinders can
provide the necessary turning moment;
•
an informational description of the
characteristics and properties of fasteners,
standard normalized parts and assemblies of
agricultural machines for the design and
execution of the controlled CP axis was
produced, the composition of data attributes
was identified to support decision-making in
the design and manufacturing process;
•
An information base of standard normalized
parts and assemblies of agricultural machines
has been created, a decision support
algorithm has been developed for their choice
for the design and execution of the controlled
CP axis;
•
Algorithms for calculating structural and
dynamic parameters have been developed to
assess the performance of the controlled CP
axis under extreme operating conditions.

The results of this work are the introduction of a
modernized CP into agriculture, which provides
stability when driving, a decrease in the turning
radius during machine cotton picking, and a
simplification of the CP design while increasing its
reliability when performing agrotechnical
operations.
The technical and economic indicators of the
results are expressed in increasing the efficiency
and quality of obtaining reliable information in
the process of designing the controlled axle of the
cotton picker, as well as in the rational use of
labour, energy, material and financial resources
for research, diagnosis and manufacturing of
products.
