Technical condition diagnostics of potato combine harvester

Abstract

Abstract The technical condition of the combine harvester is one of the critical factors affecting the performance of mechanized potato harvesting. In order to maintain the required level of reliability and durability of farming machinery used for potato harvesting, the authors propose to perform maintenance checks of the mechanical drive on the lifting section of the harvester while turning the drive shaft in two modes: with free and fixed auger. This approach uncovers new dynamic maintenance parameters, which can help detect malfunctions in the safety clutches and working components of the potato harvester, determine when the safety clutches operate, and evaluate the loads acting on the transmission and related parts of the mechanical drive. The study was carried out for three harvesting seasons in the farms of the Irkutsk region using the potato combine harvester KPK-2-01+ MTZ-80. The results can be applied when setting up and adjusting potato harvesters, and when evaluating the technical condition of potato harvesting units with the required configuration.
