DEVELOPMENT OF AERODYNAMIC SIEVE GRAIN CLEANING MACHINE FOR THE FIRST STAGE OF CREATION OF A SEED CLEANING COMPLEX

Abstract

The aim of the work was to develop, manufacture and test a prototype of an aerodynamic sieve grain
cleaning machine (ARZM) of the first stage of creating a seed-cleaning selection complex for seed
preparation in breeding and seed production. The layout and parameters of the aerodynamic and screen
modules of the grain cleaning machine have been developed. The analysis of wear-resistant and shockabsorbing
polymeric materials was carried out to achieve maximum injury safety of seeds. The rational areas
for cleaning, the inclination of the sieves and the vibration drive have been determined A prototype of an
aerodynamic sieve grain cleaning machine was made, an analysis of the operation of the mechanisms of the
prototype ARZM and an assessment of the effectiveness of technical solutions implemented in the machine
was carried out. Based on the comments identified, the design and technical solutions of the prototype of the
machine were revised. Technical documentation was developed and technological processes were prepared
for the serial production of an aerodynamic sieve grain cleaning machine.
Key words: aerodynamic sieve grain cleaning machine, grain cleaning, aerodynamic module, sieve
mill, sediment chamber.
