Summary

Author: Raicov Victor Theme: “Theoretical and experimental study of operative parts characteristics of combine harvester for sugar sorgo”. PhD thesis in technic. SAUM, Chisinau, 2017. The work includes introduction, 4 chapters, 126 bibliography points, 128 pages of body text, 70 pictures, 40 schedules. The obtained results are reflected in 10 research papers. Key-words: sugar sorgo, combine, rotary harvest, dust collector system, chopping device. Field of research: technologies and technical equipment for harvest of tall-stalked crops preferred in energetic scopes. Goal of research: development of aggregate, which will provide the harvest of sugar sorgo and its preparation as row product for producing of bioethanol. Tasks: development of the optimal and framing scheme of the combine, selection of technical characteristics, provided implementation of technological process, comprehensive grounding of geometrical and kinematical parameters of the working body. Scientific novelty of receipt results: the theoretical grounding and experimental confirmation of usage in the system of dropping stalks of felting with supple blades, fixing of strong characteristics of sugar sorgo stalks by pressure by residual damageability criteria, usage in dust collector system of cross flow fan. Presented harvester has found application in the farms engaged in the harvesting and processing of tall-stalked crops, including for energy purposes. This will contribute to the solution of the problem of energy security of the Republic of Moldova and other countries.
