The invention discloses a device and method for collecting atmospheric biological particles of an unmanned aerial vehicle, belonging to the field of agricultural technology. Connected with the retractor; the opening and closing mechanism is composed of umbrella ribs, umbrella poles, rotating parts, and guide rods. The umbrella ribs and pods are rotatably connected by a driver. One end of the guide rod is installed on the pod, and the other end is set on the umbrella ribs. The rotating part on the upper part is slidingly connected, and the rotating part and the umbrella rib are screwed together; the sampling workpiece is arranged on the umbrella pole; the power supply facility is electrically connected with the retractor and the driver respectively. In the present invention, the collection device is hung on the unmanned aerial vehicle to sample the atmospheric biological particles in the high altitude, which is beneficial to overcome the limitation that the diffusion of the atmospheric biological particles cannot be reflected in the low altitude. The invention can accurately and continuously complete the sampling operation of biological particles in the atmosphere, and has the characteristics of compact structure, efficient collection, stability and reliability.
Description
technical field [0001] The invention belongs to the technical field of agriculture, and relates to a device for collecting atmospheric biological particles of an unmanned aerial vehicle and a method thereof. Background technique [0002] In the prior art, the dispersion of biological particles in the atmosphere has always been a key topic in the study of agricultural ecosystems, and it is a key technology in the study of the spread of invasive species, the change of ecological populations, and the tracing of pollen allergens. Due to the light weight and small size of biological particles that travel with the wind, the variation range of propagation height and distance is large, and the atmosphere itself changes rapidly, the sampling of biological particle drift has always been a constraint for the study of atmospheric propagation of biological particles. To capture as much as possible the biological particles that drift with the atmosphere, such as pollen, seeds, etc., to in...
