Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment：A kind of soil profile sampler, as shown in Figure 1, including first sleeve 1 and the second casing 2, the second casing
2 are set in first sleeve 1, and the inner wall in 1 lower part of first sleeve is equipped with screw thread, and the outside of 2 lower part of the second casing is along its length
Direction is equipped with one section of screw thread, can realize the screw-thread fit between first sleeve 1 and the second casing 2.In the bottom end of the second casing 2
Equipped with conical blocks 3, detection sampling personnel are facilitated in the insertion process for being sampled device to underground, can more precisely and be saved
The insertion of the realization sampler of power.Simultaneously block 31 is surrounded by far from tapered end in conical blocks 3（As shown in Figure 3）, block 31
Can to the screw thread of first sleeve 1 be socketed realize limit, reduce because 1 turn-knob of first sleeve excessively may caused by first sleeve
1 and the second cooperation between casing 2 it is excessive, the phenomenon that slippage.
As shown in figures 1 and 3, after testing staff completes insertion of the entire sampler to underground, turn-knob first sleeve 1,
And first sleeve 1 is lifted upwards, multiple thief holes 21 are equipped on the side wall of the second casing 2（As shown in Figure 4）, with first set
Pipe 1 moves up, and each thief hole 21 is exposed to underground, while activity is plugged with multiple sampling geosynclinal blocks 22 in thief hole 21, sampling
The one end of geosynclinal block 22 far from the second casing 2 is equipped with notch, can realize the acquisition to soil sample.In the upper and lower ends of sampling geosynclinal block 22
Equipped with convex block 221, connected by compressed spring 222 between 2 inner wall of convex block 221 and the second casing, one end of compressed spring 222 with it is convex
Block 221 is fixed, and the other end is fixed with 2 inner wall of the second casing, can realize horizontal extension of the sampling geosynclinal block 22 at thief hole 21.
As shown in Figure 1, in order to facilitate the sampling work of testing staff, also sliding is connected with push rod 23 in the second casing 2,
The lower end of push rod 23 is equipped with oblique angle 225（As shown in Figure 3）, sample geosynclinal block 22 and be located at one end in the second casing 2 equipped with chamfering 224
（As shown in Figure 3）, with downward sliding of the push rod 23 into the second casing 2, the oblique angle 225 on push rod 23 and sampling geosynclinal block 22
Chamfering 224 is bonded, and enables to sampling geosynclinal block 22 that can be skidded off to the side wall of the second casing 2 after stress, to be inserted into underground
Soil horizon in, realize the acquisition of soil sample.In order to improve sampling geosynclinal block 22 push rod 23 extruding under activity, sampling stability,
It is equipped with sliding block 231 in the both sides of push rod 23, the inner wall of the second casing 2 is equipped with the vertical chute 232 slid for sliding block 231, passes through
Vertical chute 232 can improve the stability of the downslide of push rod 23 to the limition orientation of sliding block 231, reduce due to unbalance stress with
And resistance it is excessive may arrive push rod 23 exert a force it is unstable.It is equipped with rotating bar 233 on the top of push rod 23, facilitates monitoring people
The force process of member adjustment and sliding.It is additionally provided with cutting edge 226 in the one end of sampling geosynclinal block 22 far from chamfering 224（As shown in Figure 3）,
So that sampling insertion from geosynclinal block 22 to underground more smoothly and stablize, reduce to push rod 23 downwards sliding may bring it is excessive
Drag penalty.
As shown in figure 3, with the downslide of push rod 23, push rod 23 squeezes sampling geosynclinal block 22 so that samples geosynclinal block 22 to sampling
It is stretched out outside hole 21, while sampling the compressed spring 222 on geosynclinal block 22 and compressing, when sampling geosynclinal block 22 is completed out of side soil layer
After sampling, testing staff slides push rod 23 upwards, samples meeting under the action of 222 elastic restoring force of compressed spring of geosynclinal block 22 at this time
So that sampling geosynclinal block 22 slides into the second casing 2 until returning back to initial position along thief hole 21.In order to reduce compressed spring
222 may occur irregular deformation affects to the activity of entire sampling geosynclinal block 22, is additionally provided in compressed spring 222 flexible
Bar 223, one end and the convex block 221 of telescopic rod 223 are fixed, and the other end is fixed with 2 inner wall of the second casing, can be with compressed spring
222 deformation and stretch so that compressed spring 222 is stretched along the direction of its axis always, is also limited simultaneously
The largest deformation amount of compressed spring 222 so that the maximum skidding distance of sampling geosynclinal block 22 is restricted, and is avoided from sample tap part
It slips.
As shown in figures 1 and 3, after testing staff slides out push rod 23, still further below slide first sleeve 21, and by with
The screw thread of second casing, 21 lower end, which is realized, to be threadedly coupled, and waits for that turn-knob to first sleeve 21 and the block 31 on conical blocks 3 contradicts i.e.
Can, and lift upwards entire sampler can by complete sampling sample take to above ground portion.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
