Abstract
In the machine technology for cultivation and harvesting of root crops and onions, one of the most important quality indicators determining the duration of root crops storage is the presence of soil and plant impurities in the heap to be stored. The impossibility to separate soil lumps from the heap of root crops and onions is due to the fact that the majority of harvesters use slotted separating executive devices, while the inter-rod distance of the separating conveyor, in order to eliminate the loss of root crops, is made smaller than the minimum size of the separated root crop, which leads to the impossibility of their cleaning on the separating executive devices of harvesters, and, consequently, to the damage of a significant part of commercial products and loss of a significant part of the crop grown during storage. The modern technologies and technical means for harvesting root crops and onions are not capable of providing high-quality commercial products with minimal labour, due to falling behind or a lack of development of technological foundations, technologies and executive devices for harvesting root crops and onions, capable of reducing or excluding the content of soil lumps in commercial products under various soil and climatic conditions. Therefore, development of mechanization tools for harvesting root crops and onions, which would allow reducing or eliminating the content of mechanical impurities in commercial products under various soil and climatic conditions, is a scientific problem, the solution of which will contribute to the innovative development of the domestic agricultural market, Russia's stable position on the foreign market.
