Mechatronic Analysis the Operation of a Pneumogravity Separator for Grain Mixtures

The analysis of the results of scientific research in the field of post-harvest processing of grain mixtures revealed that today the issue of the functioning of pneumogravity separators of grain mixtures has not been sufficiently studied. In particular, there is no mechatronic analysis of the operation of this type of separators with the introduction of an automatic correction system of the system, which does not allow implementing the principle of self-adaptation of the pneumogravity system to the changing conditions of the process of pneumoseparation of grain mixtures. Taking this into account, the work considers a mechatronic model of a pneumogravity separator of grain mixtures with elements of automation of control and auto-correction of the process of cleaning grain crops based on the designed algorithm of its functioning. Analytical studies are presented that formed the basis for the development and characteristics of the mechatronic system of a pneumogravity separator. The key element of the system is the built-in auto-correction system of the process of cleaning the grain mixture, which ensures increased efficiency. For a better understanding of the functioning, a block diagram of the separator operation has been developed, which details the stages of separation from loading the grain mass to obtaining cleaned grain. A scheme for receiving and processing data from sensors in the system control unit is also presented. The proposed algorithm for designing mechatronic systems using the example of a pneumatic-gravity separator allows significantly increasing the efficiency of pneumatic grain separation due to continuous monitoring of process indicators, data analysis, and automatic adjustment of set parameters in real time.
