Modeling the movement of onion seeds after the seeding machine

Abstract

One of the most important issues of sowing small-seeded crops (in the example of onions) is considered. The method of sowing has a great influence on crop yields. The choice of planting method is due to the need for a more uniform distribution of plants over the field area in order to optimize the conditions for their development. Studying the movement of seeds during the sowing process is the most important task, as the seeds are object of sowing. The article provides an analysis of previous work on the precision sowing of small seed crops. And also, the flight and the trajectory of the seeds from the ejection window to the bottom of the groove were studied theoretically. In the research, methods of higher mathematics, classical mechanics, and impact theory were used in which it was possible to obtain the necessary equation. Based on the numerical solution of the obtained equation, graphs are constructed that determine the trajectory of falling onion seeds when ejected from the sowing apparatus and the graphical dependence of the recovery coefficient on the height of the sowing apparatus. Also, the installation height of the metering unit was installed.
