Fastener 21.
With reference to figure 3, drilling pipe 1 is set close to 2 one end of cap is bored in opening.Fastener 21 herein can be threaded rod.
With reference to 3 Fig. 5 of figure, bore cap 2 and set in funnel-form and bore 2 top of cap and open that there are one drillings 22.
With reference to 3 Fig. 4 of figure, a drill core 3 is equipped in drilling pipe 1, drill core 3 is set along drilling pipe 1 is axial, and 3 one end of drill core is in point
Head sets and is pierced by drilling 22, and three pieces are fixed on the peripheral wall of the tip of 3 this one end of drill core and is contacted for increasing drill core 3 with soil
The friction ribs 31 of area；3 other end of drill core is closed one end with drilling pipe 1 and is arranged at intervals.Four are provided on 1 inner wall of drilling pipe around drilling pipe 1
The limiting slot 5 that the angles such as axis are set, limiting slot 5 include circumferential sections 52 and axial direction part 51, and axial direction part 51 is opened along drilling pipe 1 is axial
If circumferential sections 52 are opened up around 1 axis of drilling pipe, and axial direction part 51 is connected close to 2 one end of cap is bored with 52 one end of circumferential sections.Drill core 3 is remote
From four gag lever posts 32 are fixed on the peripheral wall for boring 2 one end of cap, four 32 grade angles of gag lever post are set, and four gag lever posts 32 are remote
From 3 one end of drill core difference gap in corresponding circumferential sections 52.Cushion pad 521 is fixed on the cell wall of circumferential sections 52,
Cushion pad 521 is used to disperse the abutting power between 52 cell wall of 32 peripheral wall of gag lever post and circumferential sections.When drilling pipe 1 rotates forward, due to soil
Earth has the frictional force that it is hindered to rotate to drill core 3, then gag lever post 32 will be pushed against slot of the circumferential sections 52 away from 51 one end of axial direction part
On wall.When drilling pipe 1 stretches to the soil layer of predetermined depth, drilling pipe 1 inverts, at this time since soil has drill core 3 its rotation of obstruction
Frictional force, then 32 one end of gag lever post will be moved to circumferential sections 52 and 51 junction of axial direction part；Simultaneously because drilling pipe 1 continue to
Lower movement, then soil have upward extruding force to drill core 3, drill core 3 section 51 will be moved up compared with drilling pipe 1 vertically at this time,
Then drill core 3 is retracted in drilling pipe 1, and soil can be simultaneously entered from drilling 22 in drilling pipe 1.

Leaf wall.When rotate backward bore cap 2 when, lower tablet 61 will be moved around 4 downward spiral of helical-blade, during this, lower tablet
61 soil that will be scraped on helical-blade 4.
Specific implementation process：First gag lever post 32 is made to slide to circumferential sections 52 away from axial away from 3 one end of drill core control drill core 3
51 at one ends of section, then rotary drilling cap 2 make lower 61 spiral of tablet topmost, bore cap 2 at this time to helical-blade 4 and just be fastened in
In drilling pipe 1, and it is relatively fixed with fastener 21 by cap 2 is bored in drilling pipe 1.
After completing aforesaid operations, drilling pipe 1 is installed on drilling machine, and starts to pierce soil layer, after being drilled into certain depth,
Start to invert drilling pipe 1, at this time since soil has the frictional force that it is hindered to rotate to drill core 3, with the rotation of drilling pipe 1, gag lever post
32 will be moved to circumferential sections 52 and 51 junction of axial direction part away from 3 one end of drill core.Simultaneously because drilling pipe 1 is continuing to move down,
Then soil has drill core 3 upward extruding force, and drill core 3 section 51 will be moved up compared with drilling pipe 1 vertically at this time, then drill core 3
In retraction drilling pipe 1, soil can be simultaneously entered from drilling 22 in drilling pipe 1, and the soil entered in drilling pipe 1 is extruded into helical-blade
Between 4.
It finally extracts drilling pipe 1 and removes drilling pipe 1 from drilling machine, unlock /V of the fastener 21 to brill cap 2, and rotary drilling
Cap 2 makes lower tablet 61 be moved out along helical-blade 4, while the soil being attached on helical-blade 4 is scraped, so as to complete to soil
The sampling of earth sample.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, several improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
