“…Operating parameters, such as threshing cylinder speed and concave clearance, are the most important factors influencing the power consumption of the threshing apparatus and the grain loss [1,10]. Usually, the operator attempts to adjust the ground speed to maintain the feed rate at a level that will maximize harvester capacity without overloading the harvester components [4,11,12]. The real-time working speed and output power of a combine harvester primarily depend on the feeding rate [13], which makes this parameter a key operating variable in such machines.…”

Corn ear feed rate variations in the threshing-separation unit of a combine harvester have a significant impact on the dynamic indicators of the threshing process. In this study, we conducted experiments using a stationary tangential threshing device and measured the forces acting on the rear part of the concave as well as the torque of the rotating cylinder during a threshing process. The ThreshLab software was developed for this purpose. We found that increasing the corn ear feed rate made the threshing process more even, due to decreasing the fluctuation of forces acting on the rear part of the concave and torque of the rotating cylinder. The corn ear threshing process may be more stable if the threshing cylinder is fitted with filler plates (FP-II). A comparison of the results obtained for variations in the forces acting on the rear part of the concave with those obtained for variations in the total torque of resistance and the speed of the threshing cylinder revealed a linear correlation between these parameters at varied feed rates.
