Static sounding sampler capable of accurately positioning and working method of static sounding sampler
The invention relates to an accurate positioning static sounding type sampler and a working method thereof.The accurate positioning static sounding type sampler comprises a pipe body and a connector fixedly inserted in the top of the pipe body, a longitudinally-arranged electric push rod is fixedly installed on the top of the inner wall of the pipe body, and a material taking mechanism used for taking an original-state sand sample is movably arranged in the position, below the electric push rod, of the pipe body; a fine adjustment mechanism used for adjusting the position of the pipe body is movably arranged below the material taking mechanism, and an alarm mechanism used for reporting the sampling depth is arranged between the material taking mechanism and the electric push rod. A second rack is matched with two gears to drive a first rack to move, so that a pipe orifice of a sampling pipe is driven to extend out of a sampling hole to take an original-state sand sample, damage to the structure of the original-state sand sample is avoided, a pipe body is driven by two overturning plates to move downwards by a small distance, and the pipe body and the sampling pipe are inclined; the undisturbed sand sample entering the sampling pipe can be conveniently separated from a soil layer, and the probability that the undisturbed sand sample falls off from the sampling pipe is reduced.
本发明涉及一种精确定位的静力触探式取样器及其工作方法，包括管体以及固定插设在其顶部的接头，所述管体的内壁顶部固定安装有纵向设置的电动推杆，所述电动推杆下方的管体内部活动设置有用于取原状砂样的取料机构，所述取料机构的下方活动设置有用于调节管体位置的微调机构，所述取料机构与电动推杆之间设置有用于报告取样深度的报警机构；通过第二齿条配合两个齿轮带动第一齿条移动，从而带动取样管的管口从取样孔伸出取料原状砂样，避免对原状砂样的结构造成破坏，通过两个翻转板带动管体向下移动少许距离，使得管体和取样管均发生倾斜，便于将进入取样管内的原状砂样与土层分开，降低出现原状砂样从取样管内脱落的概率。
