Abstract

The purpose. To minimize losses of sacchariferous mass after continuous sensorless cutting off of haulm from heads of sugar-beet by theoretical justification of height of cutting off. Methods. Methods of higher mathematics, in particular geometrical simulation and mathematical statistics, and also analysis of the gained models. Results. According to results of experimental researches and service tests of process of harvesting of sugar-beet it is revealed that the newest models of beet combines, manufactured in Europe and America, cause significant losses of sacchariferous mass. A source of these losses is in the core the bad cutting of heads of root crops of sugar-beet, to be exact — excessively low point in which cops are sawed. That leads to straight loss of sacchariferous mass. Thus, there is a necessity of searching engineering decisions which will allow to avoid both losses of sacchariferous mass, and sticking of residues of haulm to root crops. Results of research in distribution of heights that root crowns protrude above the soil surface confirmed the hypothesis that it follows the normal distribution. Conclusions. On the basis of the gained results it is established that normal allocation has such statistical parameters: mean deviation r=20…30 mm, expectation m=40…60 mm. Also dependence of losses of sacchariferous mass on height of cutting of haulm from head of root crop of sugar-beet is gained.
