RESULTS OF FIELD RESEARCH OF HARVESTING OF WHITE LUPINE BY MODERNIZED COMBING HEADER "OZONE"
The article emphasizes the relevance of the use of leguminous crops. One of the main aims of cultivating these crops is emphasized: obtaining high-protein food, fodder or technical raw materials. The plant is a white lupine included in the register of breeding achievements that are allowed to be used on the territory of the Russian Federation. Crop areas, which are increasing and this is due to the acute problem of production of vegetable protein. The harvesting of white lupine using the technology of plant hair on the root is considered. In the field studies, a stripping reaper of the "OZON" type of PAO "Penzmash" was used. The header was modernized to harvest white lupine with a change in the design of combing combs in accordance with the solutions proposed in the patents for utility models RF № 172995 and № 178721. Experimental studies of new working organs have been carried out and technological parameters and operating conditions of combing header on white lupine harvesting have been determined. The methods of planning the experiment were used, the studies were carried out according to plan 33. Field studies were carried out in the Michurinsky Districts of the Tambov Region to harvest white lupine of the Degas variety. The results obtained during the experiment were subjected to statistical processing performed in the program Statistic 13.0 to obtain two-dimensional cross sections of the investigated factors. The analysis of the obtained data shows that the optimal values of the investigated factors are within the following limits: kinematic index λ=24…27; the height of the header from the soil to the comb in the lower position h_g= 0,38…0,42 m and the height of the contact point of the fairing with the plant h_0= 0,7…0,75 m.
