JUSTIFICATION OF THE METHOD OF PERFORMANCE IDENTIFICATIONTRIERS ON THE RESULTS OF STANDBY RESEARCH
The possibility of using cyclic action stands to reveal the dynamics of the continuous process of isolating the grain of the main crop from a grain mix adapted to an arbitrary length of the cellular surface is justified. The prerequisites for the development of a method for identifying consumption characteristics, which confirm the possibility of reproducing a real technological process using a cyclic action stand, are defined.The sequence of actions based on interval estimates of the allocated masses of the main crop grains from the grain mix is justified.Mathematical dependencies for calculating the productivity of grain separation from a grain mix using a standard or projected by a cylindrical barrel of arbitrary length are obtained. Calculated information on the relationship between the speed of the axial displacement of the segment, the time of movement of the grain-mix segment to the length of the bench mesh cylinder with the load of the stand and the speed regime of operation was obtained on the basis of the generalization of the researches of Professor M. Letoshnev. taking into account the properties of the working environment and the investigated range of the high-speed mode of the stand. Calculation of the productivity of a standard mesh cylinder according to the results of interval estimates of the isolated masses of the main crop grains from a grain mix using a stand showed that the proposed method allows to reliably determine the productivity of mesh cylinders of arbitrary length. The selected speed range (30... 45 rpm) of the stand for process analysis provides a change in the flow characteristics within the limits of 1.17... 4.98 t / h, which is sufficient for the controllability of existing trier units according to the performance criteria in a wide range of initial properties grain mixture.Advantages of the proposed method are the ability to determine: the effective length and length of the free part of the cellular surface; the values of the grain loss for the randomly chosen length of the mesh cylinder; dynamics of grain separation along the length of the working surface.
