It is known that the process of cleaning weed impurities from cotton is complex and, theoretically, this process has not been adequately studied. The reason for this is that the forces that bind weed impurities and fibers have not been studied. Applied modern power circuits are insufficient to classify this process. Therefore, it is advisable to study this process using other methods. The article presents the patterns obtained as a result of theoretical researches, describing the processes of effective separation of weed impurities from cotton. As a result of the movement of the cotton mass on the outer side of the mesh surface, contact occurs between the weed impurities in the cotton composition and the mesh surface, as a result of which under the influence of these forces some weed impurities are brought out through the open sections of the net. To describe this process A.G. Sevastyanov proposed a model. According to this model, a decrease in the amount of weed impurities in cotton on a mesh surface is proportional to its quantity and speed of movement along the mesh surface. In accordance with this model, theoretical studies of the process of separation of weed impurities from volatiles of cotton have been carried out. To simulate the process of shedding of volatile matter, it is necessary to determine the speed of movement of cotton volatiles on a mesh surface. In this paper, a second-order differential equation is presented, with the help of which it is possible to determine the motion of a volcano contour along an arbitrary shape of a mesh surface curve. The results of theoretical studies and laboratory tests of the device allow us to develop practical recommendations for the practical implementation of an innovative vertical cleaning machine, the choice of working units and their rational geometric parameters.
