Precision seeding working system and method based on unmanned aerial vehicle platform

Abstract

The invention discloses a precision seeding working system and method based on an unmanned aerial vehicle platform. The system comprises an unmanned aerial vehicle (1) and seeding devices (2) fixed on the unmanned aerial vehicle. Each seeding device (2) comprises a seed box (15), a fixed seat (16), a wind power seed scattering device, a quantitative seeding roller (18), roller blades (19) and a servo motor (22); the servo motor is driven by a battery; the wind power seed scattering device is a fan (17) only or an air supply channel consisting of a fan and a sleeve; the seed box (15) is fixed on the top of the fixed seat (16); the servo motor (22) is mounted on the fixed seat; the quantitative seeding rollers (18) controlled by the servo motor realize precision seeding; by the adoption of the wind power seed scattering device, seeding is uniform. The precision seeding working system based on the unmanned aerial vehicle platform can realize precision seeding work and is high in seeding efficiency and easy to implement.

Description

technical field [0001] The invention relates to a precise seeding operation system and method based on an unmanned aerial vehicle platform. Background technique [0002] At present, my country's agriculture is developing rapidly, and agricultural modernization urgently needs agricultural mechanization and high-efficiency and precise operations. The sowing of existing farmland is a high-tech, high-precision operation, and the sowing effect is obviously affected by various factors, and very high requirements are put forward for the sowing method. The current artificial sowing includes manpower and mechanical sowing. Manpower sowing is not only labor-intensive and inefficient, but also has obvious uneven sowing, which reduces the quality of sowing and takes a lot of time; mechanical sowing replaces manpower sowing, which can effectively improve work efficiency, but the existing mechanical sowing is mainly limited to two forms of hand-held mechanical sowing and walking mechanic...

AI Technical Summary

Problems solved by technology

However, during the sowing operation, the seeds are scattered from the seed box into the farmland in a free-fall manner, and the seed spacing is too small; secondly, the sowing in the farmland needs to be sown quantitatively, and the seeds are too dense to affect the quality of the seeds, and the farmland resources are wasted if they are too sparse; The size is affected, the seed box must have a switch control

Therefore, there are still many problems in the seeding operation, such as seed uniformity, farmland seed density, and seed box switch control, which reduce the operating efficiency of drone seeding and the seeding effect is not good.
