Unmanned aerial vehicle with forest heavy metal spectrum inversion and sample collection functions

Abstract

The invention discloses an unmanned aerial vehicle with forest heavy metal spectrum inversion and sample collection functions. The unmanned aerial vehicle comprises an unmanned aerial vehicle body, asample collection device and a plurality of sets of sampling mechanisms, wherein the sampling mechanisms are arranged on the sample collection device and communicate with the sample collection device;the sample collection device is arranged at the bottom part of the unmanned aerial vehicle body; each sampling mechanism comprises a drill bit, an inner cylinder and an outer cylinder, the bottom part of the inner barrel and the top part of the drill bit rotate relatively, the inner wall of the outer barrel abuts against the outer wall of the drill bit, a suction mechanism is arranged on the inner wall of the outer barrel, a cavity used for being communicated with the inner barrel is formed in the drill bit, the tail end of the cavity is flush with the outer wall of the drill bit, a first hose fixedly connected with the inner barrel is arranged in the inner barrel, the cavity is communicated with the first hose, the first hose is sleeved with a plurality of annular second hoses, and magnetic sheets are arranged on outer walls of second hoses. According to the unmanned aerial vehicle, accumulation of soil on the inner wall of the conveying pipeline can be reduced, the situation that the soil is difficult to remove due to wrinkles on the inner wall of the pipeline can be avoided, and the situation that data errors generated by subsequent detection work are too large is avoided.

Description

technical field [0001] The invention relates to a construction device, in particular to an unmanned aerial vehicle with the functions of forest heavy metal spectrum inversion and sample collection. Background technique [0002] Due to the limitations of its spatial resolution and spectral resolution, satellite images cannot be applied to some forest environment monitoring. Setting hyperspectral remote sensing sensors on UAVs can collect object reflectivity in different spectral bands, thereby realizing remote and rapid sampling. However, it is difficult for traditional collectors to obtain spatial forest data information, and because each data collection has a single function, it is not possible to collect forest soil samples at the same time, and the existing forest soil collection devices are poor in use and cannot The soil at different depths is collected, and a large part of the soil will remain on the inner wall of the conveying pipeline, so that the soil samples at dif...
