Experimental Research of Stripping the Leaves from Root Crops

Abstract

Modern trends in root crop machinery include the development and implementation of highly efficient, energy-saving and technologically reliable harvesting systems and facilities into agricultural production. The main criteria for meeting these demands are the digging quality and root crop impurities separation characteristics. The objective of research is the justification of design and kinematic parameters of cleaning tools. The paper provides description of the experimental unit and procedures for experimental research of the process of stripping the haulm residues from root crop heads. A histogram and polygon were plotted for probability density function of random variables of the length of leaf remnants on root crop heads. The differential law for a probability density function of length of leaf remnants after the stripping by cylindrical rollers was obtained. The approximate linear dependence was obtained as a regression equation, which describes a change in the length of leaf remnants on the root crop heads depending on the diameter and rotation speed of rollers. The aforementioned method and results obtained in experimental research can be used by specialists at design engineering bureaus for development of new or improvement of existing combined cleaning systems.
