Unmanned aerial vehicle rice electromagnetic ejection broadcaster

Abstract

The invention provides an unmanned aerial vehicle rice electromagnetic ejection broadcaster, which comprises an external acceleration device, a reset device and a seed conveying device, and is characterized in that the external acceleration device mainly comprises a driving coil and a lower limiting device consisting of a buffer pad a, a lower end insulation blocking cover and a compression spring a; an inner metal shell of the seed conveying device drives a seed outlet pipe to integrally move downwards under the action of an alternating magnetic field generated by a driving coil, and after the inner metal shell encounters a lower limiting device, the inner metal shell stops moving downwards, the seed outlet pipe continuously moves downwards due to inertia, and a bud-shaped seed outlet head at the lower end of the seed outlet pipe is separated from a clamping module, so that the seed falling speed is increased, the kinetic energy of the seed conveying device is increased, so that the speed of seeds reaching soil is increased, the position error in the unmanned aerial vehicle aerial seeding process is reduced, and the unmanned aerial vehicle precision seeding development process is promoted. The resetting device is provided with an elastic element and is used for resetting the seed conveying device to prepare for next sowing.

Description

technical field [0001] The invention relates to an electromagnetic catapult spreader for unmanned aerial vehicle rice, belonging to the technical field of agricultural machinery unmanned aerial vehicle sowing. Background technique [0002] Rice is an important grain product in China, and its output accounts for more than half of my country's grain output. With the development of my country's social economy, the adjustment of agricultural structure, as well as the transfer of rural labor force and the aging population, the traditional rice cultivation technology based on manual labor can no longer meet the needs of rice production in my country. Rice light simplification and mechanized planting Become the key to improving labor productivity and solving labor shortage. Rice sowing drones can effectively break the restrictions of land conditions in hilly and mountainous areas, and are not restricted by special-shaped fields. They can operate more freely, have higher seeding eff...

Problems solved by technology

[0003] The UAV realizes the aerial sowing operation through navigation remote control or ground remote control. However, in the aerial sowing UAV in the prior art, the seed grains fall freely from the seed tube to the soil by gravity and are affected by the wind field of the rotor. The problem of offset and poor uniformity will lead to unstandardized sowing and uncontrollable rice plant population structure, which will affect the permeability and growth rate of subsequent plant populations, resulting in inconsistent seeding volume and effect. The power-assisted seeding device that reduces the wind field disturbance by the falling time is to be studied
