Pneumatic sowing unit and sowing method of agricultural unmanned aerial vehicle

Abstract

The invention discloses a pneumatic sowing unit and sowing method of an agricultural unmanned aerial vehicle, which comprises a shell, a feeding port is formed in the top of the shell, a discharging port is formed in the bottom of the shell, a disc is arranged in the shell, a discharging channel is formed in the shell, an opening is formed between the top of the discharging channel and the shell, the discharging port is located at the bottom of the discharging channel, the disc is rotationally connected with the shell, and seed suction holes are formed in the disc. Ordered direct sowing in the prior art can be achieved through the technical scheme, direct sowing of an unmanned aerial vehicle or ground equipment only achieves sowing and drilling and belongs to the disordered direct sowing state at present, ordered hole sowing is achieved through the technical scheme, and in other words, regular line-forming hole-forming particle direct sowing is achieved, field ventilation and illumination conditions are improved, and the seedling rate and the quality of rice in the later period are improved.

Description

technical field [0001] The invention relates to the field of plant protection drones, in particular to an agricultural drone pneumatic sowing unit and a sowing method. Background technique [0002] The plant protection UAV realizes the spraying operation through ground remote control or navigation flight control, and can spray chemicals, seeds, powder, etc. However, the plant protection drones in the prior art have the technical problem of poor sowing uniformity in their seeding boxes, and it is not practical to sow corn, beans and other crops that require high precision in the number of sowing in a single hole and strict control of row spacing. In the plant protection drones in the prior art, the seeds broadcast by the sowing device freely fall into the soil by gravity, and the seeds are on the surface of the soil, and usually need to be covered with soil after sowing. [0003] In the prior art, the invention patent with the publication number "CN201921198072.6" discloses ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the invention patent with the publication number "CN201921198072.6" discloses a drone sowing device, which completes the sowing by sowing the seeds downward. However, during the sowing process of rice seeds, due to the nature of the rice field , so under the action of gravity, the sown seeds can only float on the water surface, and cannot achieve good seed fall
