Experimental research of the device with elastic combs for flax deseeding

Flax producing branch represents a considerable part of agro-industrial complex of the Republic of Belarus and is regarded to be a serious export potential of the country. Efficiency of the work of flax producing branch is determined with the quality of received production and its cost estimation. In its turn, production quality directly depends on strict compliance with the agro-technical requirements, especially, harvesting process. Therefore, development of qualitative economically effective flax harvesting equipment, appropriate to the international standards of flax harvesting, appears a serious scientific and practical problem. The article presents the methodology and results of experimental studies on the threshing degree detection of flax tape by means of device with flexible combs, the mathematical model is obtained and three-dimensional cross-sections of the response surface characterizing threshing rate depending on the selected factors and their variation intervals are constructed.
