MAIN TRENDS IN MOBILE GRAIN CLEANING EQUIPMENT DEVELOPMENT
For the first time the classification of mobile technical equipment for post-harvest cleaning of grain is developed. Based on the classification, the current state of that issue in the leading grain producing countries and in Russia is studied. The conducted analytical research shows that the application of mobile grain cleaning machines, units and complexes is economically reasonable for farms; the approach to post-harvest grain handling cardinally changes. The directions for the development of mobile machinery technologies and arrangement are shown. The creation of mobile modular technological equipment adapted to the natural and climatic conditions of a particular region, Siberia, for example, should be a priority. The classification of the main principles of mobility of certain grain cleaning machines and operation lines reveals the possibility for their application in the process of post-harvest grain handling in Russia. For example, self-propelled machines are applied in agriculture for a long time already. The easiest way of transition to mobile technology is the application of the machines mounted on trailer units, special platforms or truck cargo box. It is possible to interlink mobile grain cleaning complexes with harvesting operations with higher functionality, harvesting-transportation cleaning complex, for example. Large scale research and industrial tests are required for further development of such technologies.
