Material spreading device, unmanned aerial vehicle and material spreading method

Abstract

The invention discloses a material spreading device, an unmanned aerial vehicle and a material spreading method. The material spreading device comprises a material taking device, a material receivingdevice, a feeder and a controller, wherein the material taking device comprises a shell with an upper opening and a lower opening; the upper opening is communicated with a material box; a material taking wheel is located at the lower opening and driven by a driving piece to rotate; a material taking cavity used for containing materials is formed in the material taking wheel; the controller is electrically connected with the driving piece; the material receiving device is located below the material taking wheel and communicated with the feeder, and materials in the material taking cavity enterthe feeder through the material receiving device and are scattered by the feeder. In the material spreading process, the controller controls the driving piece to drive the material taking wheel to rotate at the corresponding rotating speed, accurate material taking of the material taking wheel can be achieved, and accurate control over the material spreading amount by the unmanned aerial vehicle is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a material spreading device, an unmanned aerial vehicle and a material spreading method. Background technique [0002] With the development of agricultural machinery, agriculture has gradually realized semi-automation or even full automation. At present, mechanical sowing in agricultural production can include hand-held mechanical sowing and walking mechanical sowing. Hand-held mechanical sowing still requires workers to carry sowing equipment to the ground to sow. However, in the case of complex farmland terrain, there are many problems such as difficulty in going to the field, low speed and difficulty in turning around. [0003] As the flight technology of small and medium-sized UAVs gradually matures, UAVs have the advantages of vertical take-off and landing and are not affected by terrain, making it possible for UAVs to sow seeds. At present, most of the mater...
