Experimental studies of grain material separation by a sieve track

In the process of postharvest handling the greatest load on cleaning and sorting the heap coming from the combines falls on grain-cleaners with sieve working bodies. The limitation of the increase in the separation efficiency of the passage fraction from the grain heap by the sieve working bodies is the principle itself in which the material being processed moves along the grating surface during the separation process. It is shown that an increase in the separation efficiency of the passage fraction is possible through the use of grain-cleaners as a working body of a conveyor sieve boot. A functional diagram of a conveyor sieve boot is proposed. The influence of the main kinematic parameters of the conveyor sieve boot on the qualitative and quantitative indicators of the separation process is presented.
