Reduction of energy consumption, which creates hygienic root crops, is achieved with the use of expanded boxes of new technologies and improved pick-up modules, which is an urgent scientific task. Tests of the energy-saving method of growing plants are given and what is more, the scheme of experimental installations (put into operation of the plant harvesting module) and the methods of experimental field factors used in roots have been provided. Analytical and empirical dependencies are obtained, which characterize the change of the second feed and the specific mass of the cut and chopped knife of the rotary saw cutter, depending on the velocity of the module, the yield capacity and the density of chicory root crops plantation. The specific mass of the plant harvested from 3 rows of root crops are, respectively, in the range from 17 to 36 (kg/s) and from 19 to 27 (kg/m2). The results of the experimental studies were processed using Statistics 10, the confidence level P = 0.95, the Fisher F-criterion F = 100.8> Frit and the t-alpha criterion t = 2.05. Based on the graphical constructions it was established that the discrepancy between theoretical and experimental values of the second feed and the specific gravity of the ridge ranges from 10 to 15 (%). |
