The invention discloses a device and method for collecting atmospheric biological particles of an unmanned aerial vehicle, belonging to the field of agricultural technology, comprising a hanging part, a pod, an expander, a power supply facility, a driver, a rotary mechanism and a collection bin; the hanging part is connected with the expander; The slewing mechanism is composed of main shaft, auxiliary shaft, main gear and auxiliary gear; the collection chamber is provided with a panel that can rotate with the auxiliary shaft on the side where the auxiliary shaft is located, and a plurality of sampling workpieces arranged in a matrix are arranged on the panel; power supply facilities It is electrically connected with the retractor and the driver respectively. In the present invention, the collection device is hung on the drone 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 an unmanned aerial vehicle atmospheric biological particle collection equipment and method.Background technique[0002]In the prior art, the dispersion of biological particles in the atmosphere has always been a key subject in the study of agricultural ecosystems. It is also a key technology in the study of the proliferation of invasive species, changes in ecological populations, and traceability of pollen allergens. Due to the fact that the biological particles propagated by the wind are light in weight, small in size, wide range of propagation height and distance, and rapid changes in the atmosphere themselves, the sampling of biological particles has always been a constraint on the study of atmospheric propagation of biological particles. As much as possible to capture biological particles, such as pollen, seeds, etc., that are floating with the atmosphere, and to increase the opportuni...
