Study on the Wear of Hardened Opener Shares of the Grain-Fertilizer-Grass Seeder

Abstract: The importance of this study lies in the fact that the wear of the working bodies of seeding machines leads to an increase in fuel consumption, which results in increased costs and a deterioration in the quality of seeding, thus leading to a decrease in yield. This paper aims at studying the state of hardened working bodies of a grain-fertilizer-grass seeder. Based on the results of existing information and the possibility of further implementation of shared hardening technologies, the following methods of improving wear resistance were adopted – (i) electric arc surfacing with hard-alloy electrodes and Sormayt®, and (ii) hardening share by high-frequency heat treatment. To carry out this study, samples of the opener shares of a grain-fertilizer-grass seeder, made of the structural spring steel 65Mn, were used. An ultrasonic flaw detector was used to study the condition of the worn-out surface layer of the opener shares. These studies allowed us to establish that the strengthened samples increase the hardness of the material. On the basis of experiments with rotatable central composite design, the optimal parameters for achieving maximum hardness of the grain-fertilizer-grass seeder’s opener share were determined the material composition; a soaking time and a resistivity. Under these conditions, the hardness of the steel reached 94.46 HRC. Based on these results, it is recommended to replace the standard factory heat treatment with surfacing of the entire working part of the seeder openers with T590 electrodes to achieve the best shares of hardening for use in agricultural enterprises.
