The utility model aims at the above-mentioned problem that exists to current technique, provide a sample rig that soil reconnaissance construction was used, the utility model discloses the technical problem that will solve is how to improve the sample accuracy.
The purpose of the utility model can be realized by the following technical proposal: a sampling drilling machine for the investigation and construction of the soil is characterized by comprising a sampling tube and a mandrel, wherein the bottom of the sampling tube is provided with a drill bit, the sampling tube is longitudinally provided with a plurality of sampling components, each sampling component comprises a clapboard fixed in the sampling tube, the lower end surface of the clapboard is rotationally connected with a rotating block, the rotating block is provided with at least one guide cylinder vertical to the sampling tube, the outer end of the guide cylinder is connected with a pressure lever in a sliding way, a return spring in a compression state is connected between the pressure lever and the guide cylinder, the sampling tube is provided with notches which are in one-to-one correspondence with the pressure rods, a baffle is hinged in each notch, the baffle plate can seal the corresponding gap, the circle center of the clapboard is provided with a jack, the mandrel is rotationally connected in each jack, a spline hole is formed in the rotating block, and the outer wall of the mandrel is provided with an external spline matched with the spline hole.
Form a sample chamber between the adjacent baffle, the in-process that the sampling tube moved down, the dabber is controlled earlier, make the depression bar simultaneously act on the inner wall of separation blade and sampling tube, avoid the separation blade to the inboard swing of sampling tube, maintain the level and smooth of sampling tube outer wall, make the separation blade close the opening in sample chamber, to breach promptly, under the condition of rotatory sampling tube and longitudinal force application sampling tube, after the sampling tube reachd the assigned position, the rotatory dabber, make the depression bar exert outside wobbling effort to the separation blade under reset spring's effect, form "sampling blade" behind the separation blade outward pendulum, continue rotatory sampling tube and rotate certain angle, the separation blade strikes off the soil layer in the sampling tube outside, and scrape to corresponding sample intracavity, take out the sampling tube when the counter-rotation sampling tube, the soil sample of each position all is located corresponding sample intracavity.
Such benefit not only can carry out accurate sample to corresponding position when the sample, does not have the condition that the soil sample between each sample chamber scurried each other moreover after the sample to can long time save, so as to be convenient for to soil layer analysis.
In the sampling drilling machine for the civil investigation and construction, the lower end of the sampling tube is sealed.
In the sampling drilling machine for the civil investigation and construction, the upper end of the sampling tube is provided with the stress retainer ring extending out of the outer wall of the sampling tube. The stressed retainer ring is used for applying rotating and longitudinal acting force to the sampling tube.
