STUDY OF THE PROCESS OF CONTACT INTERACTION THE CLEANING BLADE WITH THE HEAD OF CHICORY ROOT CROPS
Maksym HADAICHUK – Postgraduate Student of the Department of Agroengineering and Technical Service of Vinnytsia National Agrarian University (Soniachna Str., 3, Vinnytsia, 21008, Ukraine, e-mail: max3novmac@gmail.com, https://orcid.org/0009-0008-8967-8171).
For mechanized harvesting of chicory roots, root harvesters are currently used, in which the root digging module is built on the basis of a single-disk spherical digger installed at an angle of attack to the direction of movement and a cultivator placed behind it and a horizontal drive single-shaft cleaner of the remains of the top from the root heads above it. The flexible cleaning blades, which are placed on the rotor of the single-shaft cleaner during the cleaning of the remains of the top, lose their initial rigidity, which reduces the efficiency of the root harvesting machine and the quality of the raw material from chicory roots for its processing.
The purpose of the work is to increase the technological efficiency of the chicory root digging module by developing a mathematical model of the contact interaction of the cleaning blade with the root head and optimizing the rational parameters of the single-shaft cleaner.
Based on the analysis of the technological process of the single-shaft cleaner, an analytical mathematical model was developed that functionally describes the contact interaction of the cleaning flexible blade with the root head or with the tops on it. It was established that when designing blade cleaners for tops from root heads, it is necessary to take into account the relationship between permissible deformations and the main parameters of the cleaning flexible blades - the rotation frequency of the single-shaft cleaner, the length, width and thickness of the blade, the maximum permissible number of blades in one section, the number of sections on the rotor of the single-shaft cleaner.
The constructed nomogram allows you to determine the maximum permissible thickness and minimum permissible length of the blade depending on its operating conditions. The results obtained are a further step in improving the methodology for optimizing the parameters of the working bodies of combined modules for digging chicory roots.
