IMPROVING THE STABILITY OF MOVEMENT OF SECTION OF COMBINED MACHINE FOR SOIL PREPARATION AND SOWING
Keywords:

The subject of the study is the process of operation of a combined machine for soil preparation and sowing of sunflower
and corn seeds. The technological process of the machine operation with passive rotating flat disks with flanges
installed (which properly ensure the movement of soil along the share to the ripping and separating device), a sowing
machine, a seed tube, a furrow former, a rotor, a separating grate, a parallelogram mechanism, a spring, a share is
described. The dynamic prerequisites for increasing the uniformity of the depth of furrow formation and seed
placement in depth in the soil are considered. The values of the length of the links of the parallelogram mechanism,
the initial angle of their installation and the stiffness of the spring, the deviations of the section of the combined machine
from the specified depth of the plowshare are determined. It is proved that with an increase in the length of the levers
of the parallelogram mechanism, the maximum deviations of the section increase. An increase in the initial tilt angle
of the levers of the parallelogram mechanism causes an increase in the maximum deviations. As the spring stiffness
increases, the maximum deflections decrease. The relevance of the study lies in ensuring the stability of copying the
soil surface by the working bodies of the combined machine with the depth of seed placement unchanged along the
entire length of the movement, which will make it possible to increase the speed of movement and the width of the
unit. The target group of consumers of information in the article are designers, specialists involved in the development
of tillage machines.
