“…Такие экспериментальные исследования позволяют установить общие зависимости изменения показателей надежности в различные периоды срока службы. Особенно это важно во время действия гарантии для выявления конструктивных и технологических недоработок и создания рекомендаций по их устранению [17][18][19].…”

Introduction. Grain harvesters are used for no more than two months within a year. They must have maximum operating reliability, since even short downtime during the harvesting period result in large crop losses. The purpose of the study is to identify the causes of combine harvester failures within the warranty period. Materials and Methods. Identifying consequences of failures and ensuring the reliability of grain harvesters are based on an improved classification of failures. In the process of studying, there have been proposed the ways to solve the problem of combine harvester downtime based on the analysis of the time for grain harvester troubleshooting. The category of severity of failure consequences was taken into account. Results. Through monitoring in the period from 2018 to 2020, there were found failures of units and systems of grain harvesters with low reliability indexes within the warranty period. Most of the failures (59.2%) were found in Russian-manufactured combines, of which operational failures are 55.9%, structural failures – 26.7%, and production failures – 17.4%. The general patterns of changes in the average time for combine troubleshooting have been determined. A geometric model of a detail for the trouble-free operation of combines (header auger shaft) was created. The finite element analysis (ANSYS) was used to identify parts, which are subject to maximum workload. There have been identified units and parts, which fail to function within the warranty period, because of design and technological defects. Discussion and Conclusion. In order to reduce the time to find the consequences of failures, it is necessary to create a more extensive network of enterprises providing a wide range of services, improve the organization of technical service and expand direct links with the manufacturers of equipment in order to respond quickly and make the necessary design and technological decisions.

“…Among the technical reasons for reducing the performance of technological processes of combine harvesting, it is possible to single out the indicators related to the aspects of managing the technical condition of combine harvesters -repair and maintenance of machines [4][5][6]. Maintenance is an integral part of the operation system of machines, without which it is impossible to ensure their proper functioning throughout the service life of the machine.…”

Performance analysis of the process of combine harvesting of grain crops

et al. 2020

The effectiveness of combine harvesting processes is one of the most important indicators of planting enterprises, as it largely determines the efficiency of the entire organization. One of the problems in assessing the effectiveness of combine harvesters is the determination of the planned performance of machines with rated productivity. The paper considers approaches to determining the planned and actual performance of the processes of combine harvesting of grain crops. The factors affecting the decrease in the performance of combines have been studied. The analysis of data on the wheat harvesting process in local organizations of the South of Russia during 2014-2019 has been carried out. The results of calculating the planned and actual performance of wheat harvesting processes in these farms are presented.

“…The harvesting rate and the grain amounts are significantly dependent on the seasonal load of grain-harvesting equipment [2,3]. In [4,5] it is indicated that the timeliness of field works largely depends on the seasonal load of technical means. The problem of the harvesting campaign is worsened by climatic conditions [6,7].…”

Justifying the productivity of a grain dryer in the climate of the Southern Urals

The use of grain-drying complexes is established to make possible to start harvesting before the crops are fully ripened, to shorten the harvesting period, to increase the productivity of combine harvesters and reduce production losses. An economic and mathematical model is developed to justify the productivity of grain-drying equipment, taking into account the rate of grain supplied from the field. Simulation made possible to reveal the rational productivity of a grain dryer taking into account a wide range of natural and production factors. The dependence of the operation of combine harvesters on the moisture content of the grain mass is obtained. It is established that the use of crops with different growing periods in crop rotation makes possible to expand the rational range of harvesting equipment and grain-cleaning complexes, to reduce the total cost of production.
