Variable-rate fertilization device with unmanned aerial vehicle

Abstract

The invention discloses a variable-rate fertilization device with an unmanned aerial vehicle. A high-definition camera and a GPS positioner are arranged at the front end of the unmanned aerial vehicle, a fertilization assembly is arranged on the unmanned aerial vehicle, a controller carries out variable-rate fertilization according to feedback signals of the high-definition camera and the GPS positioner, the fertilization assembly has a fertilization-rate-adjustable structure, thus, the fertilization rate can be adjusted automatically according to the feedback signals of the high-definition camera and the GPS positioner, and the fertilization rate is adjusted by adjusting the rotation speed of a fertilization wheel and the number of troughs which are in direct contact with fertilizers in afertilizer storage bin. Automatic fertilization of the unmanned aerial vehicle can be realized, furthermore, the fertilization rate can further be adjusted automatically or the discharge rate of fertilization is adjusted automatically, two fertilizers can be applied simultaneously, the fertilization effect is good, the discharge rate of fertilization can be adjusted, the adjustment range is large, and the variable-rate fertilization device with the unmanned aerial vehicle is suitable for application of various fertilizers, and is high in fertilization applicability.

Description

technical field [0001] The invention relates to a UAV variable fertilization device, which belongs to the technical field of UAV fertilization for agricultural automation. Background technique [0002] An unmanned aircraft is an unmanned aircraft operated by radio remote control equipment and self-contained program controls, or operated entirely or intermittently autonomously by an on-board computer. According to the application field, UAV can be divided into military and civilian. In recent years, drones have become more and more common for civilian use. At present, they are used in aerial photography, agriculture, plant protection, micro selfie, express delivery, disaster relief, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reports, power inspections, disaster relief, film and television Applications in fields such as filming and romantic creation have greatly expanded the use of drones themselves, and developed countries are...

AI Technical Summary

Problems solved by technology

The current drone fertilization is still relatively small, especially because the fertilization process requires variable fertilization for different growths or different soil properties in the field, which increases the difficulty of drone fertilization. The current fertilization structure is generally quantitative fertilization , it is difficult to control the amount of fertilization or the rate of fertilization during fertilization, and it is difficult to truly achieve variable fertilization
