Design of precision seeding device based on hexarotor UAV platform and its application in hard soil

Abstract

Drones, also known as unmanned aerial vehicles (hereinafter referred to as UAV), are widely used in both military and civilian applications, but agricultural drones have made great strides in recent years. Agricultural drones are often used to detect and evaluate crops, aid crop pollination, and spray fertilizers and disperse seeds. However, in terms of seed seeding, the vast majority of drones can only achieve extensive sowing of seeds, and seeds can only be sown on the surface of the soil, and the sowing accuracy of this method is extremely low, and there is a large waste of seeds. In order to improve the sowing efficiency of UAVs and the sowing effect on hard soil, this paper conducts relevant research on the seeding device carried by UAV and designs a new seeding device. On the basis of the traditional spreading function, the device performs design calculation, three-dimensional dynamic feasibility analysis, and is equipped with a precise interval sowing mechanism, which can also send seeds into the deep soil while accurately sowing seeds, which solves the problem of low efficiency of UAV seeding.
