REASONING FOR USING THE TWO-DISK DISTRIBUTING DEVICE AT GRAIN TREATMENT OF SEEDS IN LABORATORY CONDITIONS
The analysis of machinery for a grain treatment of seeds was conducted and the main problems were revealed, the elimination of the problems will allow to increase quality of grain treatment. The program of laboratory tests of the two-disk distributing device with curvilinear working surfaces is developed and presented in the article. The characteristic of sowing material of spring wheat Trizo and winter wheat Moskovskaya 56 is determined, density and dynamic viscosity of treaters being also determined by the authors. The device for determination of design and regime parameters of the two-disk distributing device with curvilinear working surfaces was developed by means of which diameters of continuous and ring disks, space between them, frequencies of rotation of disks, and their influence on unevenness of distribution of seeds by sectors of spreading are determined. At the final stage, the comparative tests on reasoning the type of distributing device were conducted. They have proved a possibility of using the two-disk distributing device with curvilinear working surfaces.
