A DEVICE FOR ADDITIONAL CLEANING OF SUGAR BEET ROOTS

Abstract

Materials of the article are devoted to the actual problem – improving the quality of cleaning sugar beet roots. In the conditions of the Middle Volga region, the harvesting of sugar beet begins in the second decade of September, which is characterized by a deterioration of the agro-physical properties of the soil, which leads to a sharp decrease in the quality of harvesting. Therefore, the sugar beet roots require additional cleaning from soil impurities after combine harvesting. The article presents the results of studies on the fractional composition of the heap and size-mass characteristics of the root crops after combine harvesting. A description of the design and principle of operation of the device for additional cleaning of root crops is given, its design and operating parameters are theoretically justified. A prototype has been manufactured and its production verification is given. It was established that at the operating speed of a feed conveyor of 2.0 m/s, the device's performance per hour of clean work was 28.0 tons, while the content of impurities in the cleaned pile did not exceed 8.0%.
