The invention discloses an atmospheric biological particle collecting device and method for an unmanned aerial vehicle, and belongs to the technical field of agriculture. The atmospheric biological particle collecting device comprises a hanging part, a pod, a telescopic device, a power supply facility, a drive, a rotary mechanism and a collecting bin. The hanging part is connected with the telescopic device; the rotary mechanism is composed of a main shaft, auxiliary shafts, a main gear and auxiliary gears; a face plate capable of rotating along with the auxiliary shafts is arranged on the side face, where the auxiliary shafts are located, of the collecting bin; a plurality of sampling workpieces which are arrayed in a matrix mode are arranged on the face plate; and the power supply facility is electrically connected with the telescopic device and the driver. The atmospheric biological particle collecting device is hung on the unmanned aerial vehicle to sample atmospheric biological particles in the high altitude, and the limitation that diffusion of the atmospheric biological particles cannot be reflected at the low altitude is advantageously overcome. Sampling operation of the biological particles in the atmosphere can be accurately and continuously completed, and the characteristics of compact structure, and efficient, stable and reliable collection are achieved.
Description
technical field [0001] The invention belongs to the technical field of agriculture, and relates to a device and method for collecting atmospheric biological particles of an unmanned aerial vehicle. 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 increase the...
