Use of vortex flows for aerodynamic threshing of agricultural crops

Abstract

The presence of self-oscillations in the vortex tube allowed threshing of various agricultural crops in it, such as rice, corn, wheat, oats, etc. For aerodynamic threshing of agricultural crops, the following installations were used: for threshing of selection samples, a tube 50 mm in diameter; for threshing corn cobs with a pipe with a diameter of 300 mm, 500 mm and a diameter of 1000 mm; threshing unit (pipes with a diameter of 1.2 ÷ 2 m), an unconventional vortex aerodynamic stand for threshing crops. According to the results of experiments, the threshing parameters are presented.
