Title:
WINTER-WHEAT TOPDRESSING DEVICE BASED ON UNMANNED AERIAL VEHICLE REMOTE SENSING
Document Type and Number:
WIPO Patent Application WO/2023/077949
Kind Code:
A1
Abstract:
A winter-wheat topdressing device based on unmanned aerial vehicle remote sensing, the device comprising an unmanned aerial vehicle body (1), a fertilizer bin (4), remote sensing cameras (11), a spraying mechanism I and a spraying mechanism II. When in use, corresponding spraying mechanisms can be selected, according to different fertilizers, for performing fertilization, thereby avoiding clogging during the process of fertilization, ensuring a smooth fertilization process and improving the efficiency of fertilization at the same time. A stirring roller (9) and an electric motor I (10) are mounted in the fertilizer bin (4). When a liquid fertilizer is to be applied, the stirring roller (9) is driven to rotate by the electric motor I (10), such that the liquid fertilizer can be sufficiently dissolved, and the clogging of a spray nozzle during spraying can be avoided. When a solid fertilizer is to be applied, the stirring roller (9) is driven to rotate by the electric motor I (10), such that the fertilizer can be prevented from clumping in the fertilizer bin, thereby ensuring a smooth fertilization process and improving the fertilization efficiency.
