Justification of the basic parameters of the rotary soil subsoiler

Abstract

The article presents materials for substantiating the main parameters of a rotary soil cultivator of a new sowing device equipped with a device for loosening the soil of non-performed primary tillage. To justify the width and diameter of the rotary ripper, consisting of 5 packages of pointed paws, tests were carried out to determine the location of corn stalks along the axis of the row. The test results were processed using mathematical statistics methods. Using the obtained formulas, distribution density curves of random variables were constructed. The width was taken from the plotted graph and based on this the diameters of the rotary shredder packages were taken.
