THE MECHATRONIC MODULE 'LINEAR ELECTRIC DRIVE - SIEVE BOOT' INTELLIGENT CONTROL SYSTEM OF GRAIN CLEANER

摘要

In our work, we represent the rationale for the need and the possibility of replacing the traditional drive of the grain cleaner with an electric drive based on a flat linear asynchronous motor. First of all, it leads to excluding mechanical transducers of motion pattern, which in its turn will increase the technical, economic and energy performance. However, the introduction of an electric drive based on a linear asynchronous motor can cause the dependence of the sieve boot acceleration on the changing mass of the grain material. To solve this problem, we proposed a mechatronic module 'linear electric drive - a sieve boot' formed by constructively merging a linear asynchronous motor with a sieve boot, as well as to implement the required motion the right intelligent system is proposed and approved. In the course of research, the ability of an intelligent system and mechatronic module 'linear electric drive - sieve boot' to maintain the specified maximum of acceleration of a sieve boot has been confirmed. When conducting in-situ testing with the implementation of our proposed intelligent control system and mechatronic drive module in an ordinary, widely used seed purifier machine MVR-2, an increase in machine performance by 12% was found out. Thus, it has been demonstrated that insignificant investments in the intelligent control of agricultural machinery nodes and mechanisms can contribute to a significant increase in capacity.
