Description

机载吹射式种子精量直播装置及无人机Airborne blown seed precision live broadcast device and drone 技术领域Technical field
本发明涉及农用设备领域，特别涉及一种机载吹射式种子精量直播装置及包含若干该装置的无人机。The invention relates to the field of agricultural equipment, in particular to an airborne blown seed precision live broadcast device and a drone comprising the same.
背景技术Background technique
采用无人机进行播种、施肥、浇灌作业的技术越来越成熟。播种是作物开始发育的第一步。然而现有技术中，无人机播种很难做到种子按要求具有行距和列距地播撒于土地上。The technology of using drones for sowing, fertilizing and watering operations is becoming more and more mature. Sowing is the first step in the development of a crop. However, in the prior art, it is difficult for the drone to sow seeds to be spread on the land with the line spacing and the pitch as required.
如公告号为CN207748033U的中国发明专利公开了一种播种装置及播种无人机，该播种装置包括外壳、传输组件和投料组件，传输组件的输料件的进料端靠近进料口设置，以使种子能够落到进料端上，并且能够在重力作用下沿输料件滑动至出料端；投料组件的转动件靠近输料件的出料端和靠近投料口设置，转动件上设有能够承装种子的载物槽，转动件能够转动，而使载物槽的位置能够与输料件的出料端的位置相对应，和使载物槽还能够与投料口相对，且载物槽的位置与输料件的出料端的位置相对应时，输料件上的种子能够在重力作用下落到载物槽中，载物槽与投料口相对时，载物

中的种子能够从投料口投出；驱动件能够驱动转动件转动。然而，上述结构在实际操作过程中，无人机在飞行时会产生很大的风力，这很难保证播撒的种子能够均匀地落于土地上。 For example, the Chinese invention patent with the publication number CN207748033U discloses a seeding device and a seeding drone, the seeding device comprising a casing, a conveying assembly and a feeding assembly, wherein the feeding end of the conveying member of the conveying assembly is arranged close to the feeding port, The seed can be dropped onto the feeding end, and can slide along the conveying member to the discharging end under the action of gravity; the rotating member of the feeding assembly is disposed near the discharging end of the conveying member and close to the feeding port, and the rotating member is provided The carrier tank capable of receiving the seed, the rotating member can be rotated, the position of the loading tank can be corresponding to the position of the discharge end of the conveying member, and the loading tank can also be opposite to the feeding opening, and the loading trough When the position corresponds to the position of the discharge end of the conveying member, the seed on the conveying member can fall into the loading tank by gravity, and the carrying object is opposite to the feeding port.
Figure PCTCN2018000378-appb-000001
The seed in the seed can be ejected from the feed port; the drive member can drive the rotating member to rotate. However, in the above structure, the drone generates a large amount of wind during flight, which makes it difficult to ensure that the seed that is planted can land evenly on the land.
又如公告号为CN104255137B的中国发明专利公开了一种基于无人机平台的精量播种作业***及方法，该***包括无人机和固定在无人机上的播种装置；播种装置包括种子箱、固定座、风力散种装置、定量播种滚轮、滚轮叶片和伺服电机；伺服电机由电池驱动；风力散种装置为单独的风扇或由风扇和套筒组成的送风涵道；所述种子箱固定在固定座的顶部；伺服电机安装在固定座上；采用受伺服电机控制的定量播种滚轮实现精量播种；采用风力散种装置使得播种更加均匀。然而，该方案中，在经过风力散种装置的作用后，种子在下落的过程中仍然会受到无人机本身的旋翼产生的风力的影响，在下落到地面时仍然会呈现杂乱无章的状态。For example, the Chinese invention patent with the publication number CN104255137B discloses a precision seeding operation system and method based on a drone platform, the system comprising a drone and a seeding device fixed on the drone; the seeding device comprises a seed box, Fixed seat, wind dispersing device, quantitative seeding roller, roller blade and servo motor; servo motor is driven by battery; wind dispersing device is separate fan or air supply duct composed of fan and sleeve; At the top of the fixed seat; the servo motor is mounted on the fixed seat; the precision seeding is realized by the quantitative seeding roller controlled by the servo motor; the wind-spreading device is used to make the seeding more uniform. However, in this solution, after the action of the wind-spreading device, the seed will still be affected by the wind generated by the rotor of the drone itself during the falling process, and will still be in a state of disorder when falling to the ground.
发明内容Summary of the invention
