Automatic and accurate pesticide feeding device and method for agricultural UAV (unmanned aerial vehicle)

Abstract

The invention relates to the technical field of agriculture, in particular to a pesticide spraying device and method, and particularly discloses an automatic and accurate pesticide feeding device and method for an agricultural UAV. The automatic and accurate pesticide feeding device for the agricultural UAV is characterized in that a first lifting unit is mounted on a trolley; a pesticide conveying box is arranged on the trolley, connected with the UAV and used for feeding pesticide to the UAV; a second lifting unit is connected with the first lifting unit, and a weighing unit is arranged on the second lifting unit; and a controller is used for controlling ascending and descending of the first lifting unit and the second lifting unit, receiving a signal of the weighing unit and controlling the pesticide conveying box to feed the pesticide to the UAV. According to the automatic and accurate pesticide feeding device, the accurate controlling of UAV dosage is achieved, the maximum take-off load is not exceeded when the pesticide is fed to the UAV, or fast and accurate feeding is realized according to a dosage requirement of accurate pesticide application, and the work efficiency of the UAV is improved; and further, the device can perform mobile operation, so that the problem that the carrying is inconvenient when the pesticide is fed to the UAV is solved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a pesticide spraying device and method, in particular to an automatic and precise pesticide dosing device and method for an agricultural unmanned aerial vehicle. Background technique [0002] At present, spraying pesticides is an important measure of agricultural plant protection work. The number of operations is large, the workload is heavy, and it has certain toxicity hazards to people. It is a hard work in agricultural production. [0003] Now, the use of drone technology to spray pesticides has entered the stage of practical application, which frees farmers from heavy and dangerous spraying operations, and is very popular among farmers. However, at present, the technology of precision spraying pesticides is mostly used on ground machines, but the technology of precise spraying of pesticides on drones has not been practically applied. [0004] The existing drones for sp...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to solve the problem that the amount of pesticides carried by the existing drones for spraying pesticides is limited by the load capacity of the drones. Taking off and loading pesticides is inefficient. When carrying a lot of pesticides, the UAV cannot take off or there are still pesticides left after spraying the crops, resulting in waste. That is, the existing UAVs cannot automatically, accurately and efficiently realize the addition of pesticides. The problem
