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.

    本发明公开了一种具有森林重金属光谱反演和样品采集功能的无人机,包括无人机、样品收集装置和若干组取样机构,取样机构设于样品收集装置上并与之相连通,样品收集装置设于所述无人机的底部,取样机构包括钻头、内筒和外筒,内筒的底部与钻头的顶部相对转动,外筒的内壁与钻头的外壁抵接,外筒的内壁上设有抽吸机构,钻头上设有用于连通内筒的空腔,空腔的末端与钻头的外壁相平齐,内筒内设有与之固定连接的第一软管,空腔与第一软管相连通,第一软管的外部套有若干圆环状的第二软管,第二软管的外壁上设有磁性片,本装置能减少土壤在输送管道的内壁堆积,能避免管道内壁皱褶导致土壤难以除去,避免出现后续的检测工作产生的数据误差过大。
