[0002] Drilling sampler is actually a kind of equipment specially used for obtaining rock, soil, peat and other samples from stratum. It can make sampling kit penetrate into underground by drilling, rotating or hammering and other ways, and extract the required sample. Drilling sampler is usually composed of power system, drilling tool, sampler and support structure. According to different application requirements and stratum conditions, the type and design of drilling sampler are also different;
