The article is devoted to the issue of development and analysis of the proposed design of working bodies for performing the operation of additional cleaning of beet heads from plant residues. In accordance with the agrotechnical requirements for growing this crop, the developed working body must provide an appropriate degree of cleaning of sugar beet heads. It is also necessary to ensure minimal injury to root crops and prevent them from being knocked out of the soil.
The issue of cleaning sugar beet heads was addressed by both domestic and foreign scientists. Designs of both active and passive working bodies are known. Passive working bodies are quite simple to manufacture, but require a high-quality tracking system and ensuring compliance with the speed of this system and the movement of the unit across the field. At the same time, active working bodies of the disk type also require the use of a tracking system but provide a better degree of cleaning. Active working bodies with flexible cutting elements provide a better degree of cleaning, do not require a tracking system for height correction, therefore their development is an urgent and necessary task.
The publication considers the issue of studying the kinematics of the movement of an improved working body of a sugar beet top cleaner. An analysis of the working environment for this pre-cleaner was carried out. A three-dimensional model of a sugar beet top cleaner was created, and a video sequence of possible movements of the working bodies was obtained. As a result of the analysis of the obtained video sequence, it was noted that the use of this type of drive ensures an increase in the effective overlap of the zone of possible location of root crop heads, as well as the action of the working elements of the pre-cleaner in the direction of maximum rigidity of most of the top residues, which improves the quality of cleaning of root crop heads.

Publisher Vinnytsia National Agrarian University
In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published 119 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Ihor Kupchuk, Candidate of Technical Sciences, Associate professor, Associate Professor of the Department of Engineering Mechanics and Technological Processes in the Agricultural Industry Faculty of Engineering and Technology Vinnytsia National Agrarian University is the chief editor of the "Vibrations in engineering and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
