Extraction of grains from ears of grain crops by grinding when opposite moving the conveyor and deck

When combine harvesters work, about half of the engine power is spent on extracting grain from ears of grain crops. The high energy costs for extracting grain from ears are due to the need to drag straw through a threshing device, the small displacement between the drum or rotor and deck, as well as to extract grain from ears of grain crops mainly by impact. Upon impact, grain damage also occurs. Therefore, the task was to develop a combine harvester that extracts grains from the ears of grain crops by grinding. For modeling, the assumption was made that the spike fell on the deck, after which it was clamped between the working branch of the conveyor and the deck strictly perpendicular to the direction of movement of the conveyor branch. The conveyor belt moves uniformly, and the deck oscillates. The movement of the conveyor and deck from the initial position is considered in the opposite direction. To efficiently removesingle grains from the ears, when the conveyor belt and deck are moved in opposite directions, it must rotate 360°. As a result of the simulation, the kinematic parameters of the process were detected during the opposite movement of the conveyor and deck. The following are determined: the speed of the belt of the upper conveyor, the angular speed of the drive shaft of the upper conveyor, the period of oscillation of the deck, the movement and the angle of rotation of the ear located between the working branch of the conveyor and the deck, when they are counter-moving. The simulation will then allow us to consider the movement of the ear during the movement of the conveyor and deck from the starting position and, based on the calculations, to identify the structural and kinematic parameters of the conveyor and deck.
