Abstract

The invention discloses a geological content drilling and sampling device for geological surveying and mining, and belongs to the field of geological sampling. The drilling depth control unit comprises a lifting plate, connecting rods, a lifting rod, a sliding column, a top ring, a bottom ring and a control power assembly, a round hole is formed in the middle of the lifting plate, the connecting rods are arranged at the two ends of the front side and the rear side of the lifting plate correspondingly, and the ends of the two connecting rods on the same side of the lifting plate are connected through the lifting rod; sliding holes in the two ends of the lifting rod are vertically and slidably connected with sliding columns correspondingly, the tops of the four sliding columns are fixedly connected with a top ring, and the bottoms of the four sliding columns are fixedly connected with a bottom ring. The drilling efficiency is high, even a hard soil layer is easy to drill, the device is stable and not easy to jack up during drilling, soil generated during drilling can be discharged to the position far away from a drill hole, the soil is prevented from entering the drill hole again, it is ensured that sampling is not affected, and meanwhile continuous drilling is prevented from being affected.
