Researching the parameters sieve of the safflower seed cleaner machine
Abstract
Sowing areas of oilseeds (sunflower, safflower, soybean, etc.) are expanding in Uzbekistan. Crops of these plants are harvested by existing grain harvesters. Grain material collected in bunker of the combine is grain mixture of the main culture, other plants and impurities of heterogeneous litter of mineral and organic origin. A small-sized machine has been developed for cleaning oilseeds from weed impurities at Research Institute of Agricultural Mechanization. Differential equations are obtained that describe the oscillatory motion of the sieve of its speed and acceleration. Based on results of decision obtained equations, influence graphs number of vibrations, angle of inclination and amplitude of sieve vibrations on length movement of the seed material on its surface over period of time crank rotations are constructed. The rational parameters of sieve are substantiated, an angle of inclination-100, number of oscillations-300 rpm, amplitude of oscillations-7.5 mm.
