Device for waterless cleaning of root crops

Abstract

Existing devices for waterless cleaning do not provide essential quality due to low efficiency either because of significant tubers damage. Device for waterless cleaning of root crops is developed in Omsky SAU which relates to the agricultural machine-building industry in particular to devices for dry cleaning of tubers from the soil, grassy impurities and haulm before sale preparation as well as for feeding preparation in technological lines of feed mills. High quality cleaning from the soil is achieved by the spiral line of pile arrangement which provides the uniform movement of the processing material heap and prevents tubers unloading due to various pile length that increases the speed of tubers rotation and provides more frequent tuber surface contact with working tools due to spring-loaded bottom providing required compression degree of processing tubers to the brush roll at the expense of dust collector that allows to get rid of small impurities during the technological process and prevents from resetting on tuber surface. Usage of this device allows to reach high quality of cleaning under low degree of damage.
