Particle material spreading device for unmanned aerial vehicle

Abstract

The invention relates to the technical field of unmanned aerial vehicle particle material spreading, in particular to a particle material spreading device for an unmanned aerial vehicle. The particlematerial spreading device comprises an air guide cylinder; a ducted fan is installed at the top end of the air guide cylinder; an outlet of the ducted fan communicates with the top end of the air guide cylinder, and the bottom end of the air guide cylinder is connected with a spreading disc; a plurality of material through holes are formed in the middle of the spreading disc, and rounded corners are arranged at the top ends of the material through holes; a ventilation opening is formed in the middle of the spreading disc; the bottom end of the spreading disc is connected with a spreading coverplate; the top end of the spreading disc is connected with a material box; and the bottom end of the material box communicates with the ventilation opening. The particle material spreading device hasthe advantages that the seed survival rate is high, the occupied space is small, and the layout design of a rack is facilitated.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle granular material spreading, in particular to a granular material spreading device for unmanned aerial vehicles. Background technique [0002] my country's large-scale land resources are insufficient, accounting for only about 30% of the cultivated land area, mainly concentrated in the Northeast Plain, Northwest Plain, and North China Plain. In the south, there are small-scale planting lands accounting for more than 60% of the total planting area. The landforms are complex, and private houses and cultivated land are intertwined. As a result, the scale of cultivated land is small, the fields are scattered, the layout of crop varieties is different, and the growth of crops is different, which largely limits the implementation of agricultural mechanization. [0003] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its o...

Problems solved by technology

[0005] However, during the actual use of the UAV, it will impact the granular materials, especially the seeds, which will affect the survival rate of the seeds. Moreover, the structure of the device is complex and takes up a lot of space, which is not conducive to the layout design of the rack.
