Abstract

The result of theoretical research is the established spreading efforts during deformation of a cotton layer by the cleaner's blades and the analyzed shapes of the deformed layer of cotton. We estimated the elastic characteristics of raw cotton and calculated spreading efforts. To determine the numerical values for the pressure forces at which a blade acts on the flow of raw cotton, for a coefficient k of the generalized properties of a material, the magnitude 𝜈 for raw cotton was adopted in a range of 0.25-0.3.

Experiments have shown that a layer of raw cotton with a thickness from 170 to 380 mm and a width of 700 mm was loaded with the force of 30-100 N concentrated along the line. Based on our calculations, it was established that 38.8%| of the raw cotton cleaning time accounts for the operation of a single blade of the roller. The result of our experimental and theoretical research is the data that make it possible to organize effective operation of cleaning machines in the cotton cleaning industry.
