Aiming at the prior art that the soil sampler combined by the inner cylinder body and the outer cylinder body is used, in the process of tunneling the soil sampler into a soil layer, the inner cylinder can rotate or move in the opposite direction of the tunneling direction under the action of the thrust force of the soil, so that the inner cylinder loosens or even is separated from the outer cylinder in the tunneling process, and the relative position of the inner cylinder and the outer cylinder is required to be fixed by hand in the tunneling process, thereby bringing great inconvenience to the exploration work.
In order to solve the technical problems, the technical scheme adopted by the invention is that the geological survey soil sampler comprises an inner cylinder body and an outer cylinder body, wherein the inner cylinder body is sleeved in the outer cylinder body, and the top end of the inner cylinder body is higher than the top end of the outer cylinder body; lifting handles are arranged on two sides of the top end of the inner cylinder body, and drilling handles are arranged on two sides of the top end of the outer cylinder body; spiral tunneling sheets spirally distributed in a cylindrical shape are arranged on the side wall of the lower end of the outer cylinder; the upper section of the outer cylinder body is provided with an expansion section, and the inner diameter of the expansion section is larger than that of the outer cylinder body; a threaded rod is arranged in the upper section of the inner cylinder and is in threaded connection with the inner wall of the inner cylinder; an inner expansion section is arranged at a position on the inner cylinder body, which is matched with the expansion section, the inner diameter of the inner expansion section is smaller than that of the inner cylinder body, and a plurality of strip-shaped grooves are arranged on the inner expansion section; the length of the threaded rod is greater than the distance from the top end of the expansion section to the top end of the inner cylinder.
In the technical scheme of this application, expansion section and interior expansion section have been increased, when the geotome was used, screw into the threaded rod to inside barrel lower extreme spiral, when the threaded rod reached interior expansion section inner wall, because the internal diameter of interior expansion section is less than the external diameter of threaded rod, so interior expansion section external diameter grow under the extrusion effect of threaded rod, thereby the external diameter that makes interior expansion section is greater than the internal diameter of outside barrel, just so make interior expansion section card in expansion section, make inside barrel can fix in the longitudinal position of outside barrel, thereby make at geotome tunneling in-process, inside barrel need not be held by hand fixedly, convenient tunneling.
Optimally, the geological survey geotome, wherein the lower end of the outer cylinder body is provided with the necking section I.
Optimally, the geological survey geotome, wherein the lower end of the inner cylinder body is provided with a necking section II.
The arrangement of the necking section I and the necking section II enables the lower end of the soil sampler to be convenient to tunnel, and resistance in the tunneling process is reduced. However, if the wall thickness of the thinnest part of the necking section I and the necking section II is too thin, the rolling edge can be caused in the tunneling process to influence the tunneling process, so that the wall thickness of the thinnest part of the necking section I and the necking section II is better when the wall thickness is 2 mm.
Optimally, the geological survey geotome is characterized in that scales are arranged on the inner cylinder body and the outer cylinder body.
Preferably, the geological survey geotome is characterized in that a positioning protrusion is arranged on the outer wall of the inner cylinder, a strip-shaped positioning groove is formed in the inner wall of the outer cylinder, and the positioning protrusion and the positioning groove are matched.
The positioning bulge and the positioning groove are arranged, so that the inner cylinder body is convenient to position in the outer cylinder body, and in the tunneling process, the inner cylinder body and the outer cylinder body are prevented from rotating relatively.
The invention has the advantages that the invention can overcome the defects of the prior art and has reasonable and novel structural design. The geotome of this application is in the tunneling in-process, and inside barrel is fixed in the position of outside barrel, can not take place relative rotation and relative slip, can not need hand at the tunneling in-process, facilitates the use.
