Sample cylinder top surface is equipped with threaded hole, connection screw thread bar in the threaded hole, and the threaded rod and sampler barrel main body are located at same axis
On, the upper end of the threaded rod is equipped with square joint, and the intracavitary of sampler barrel main body is protruded into the lower end of the threaded rod, and connects
Have an augers, the augers and threaded rod be located at it is vertical on same axis connect, also set on the outside of the sampler barrel main body
There are three support rods.
Preferably, the outer wall of the sampler barrel main body be equipped with otic placode, the otic placode be equipped with axis hole, the one of the support rod
End is equipped with through-hole corresponding with the axis hole position of otic placode, and the otic placode is bolted with support rod, and the nut on the bolt is
Wing nut.
Preferably, the sampler barrel lower body opening is along direction indention shape vertically downward.
Preferably, the support rod bottom connects downwards triangular pyramid earth anchor.
Preferably, the augers is T9A tool steel material.
Compared with prior art, having the advantage that
1. the utility model in road bed aperture and can extract soil sample, then be discharged directly to sampling bag by sample outlet pipe
Or other containers, it needs to dig out soil sample using manually sweeping and taking collections in sampling before solving, it is more convenient to operate, raising
Working efficiency, while also avoiding soil sample in sampling and splashing the safety accident for being easy to cause；
2. more convenient fixed on sample point by the laciniation used for positioning designed in sampler barrel lower body
Position, and in the earth anchor of support rod bottom installation, the triangular support knot for consolidating support rod, sampler barrel main body and ground composition
Structure avoids the problem of sampler barrel main body is subjected to displacement in sampling process, keeps this practical positioning sampling more accurate.
Detailed description of the invention
Fig. 1 is the utility model schematic perspective view；
Fig. 2 is sampler barrel main body and threaded rod connection schematic diagram；
Fig. 3 is sampler barrel main body and support rod connection schematic diagram；
In figure: 1, square joint, 2, threaded rod, 3, sampler barrel main body, 4, support rod, 5, otic placode, 6, earth anchor, 7, go out sample
Pipe, 8, augers, 9, bolt.
Specific embodiment
Here is that the present invention will be further described in conjunction with the accompanying drawings and embodiments.
Referring to Fig.1~Fig. 3, Subgrade Compaction spiral sampler, including sampler barrel main body 3, sampler barrel main body 3 be with
The cylindrical structure of hollow cavity, sampler barrel side wall are equipped with sample outlet pipe 7, and sample outlet pipe 7 is connected to 3 inner cavity of sampler barrel main body, sample
Cylinder 3 bottom opening of main body, the opening of sampler barrel facilitate insertion into and determine at sample point along direction indention shape vertically downward
Position.
The top surface of sampler barrel main body 3 is located at center location equipped with threaded hole, threaded hole internal screw thread connection screw thread bar 2, screw thread
Bar 2 and sampler barrel main body 3 are located on same axis, and the upper end of threaded rod 2 is equipped with square joint 1, and the lower end of threaded rod 2, which is protruded into, to be taken
Sample cylinder main body 3 it is intracavitary, and be connected with the augers 8 of T9A tool steel material, augers 8 is located at same with threaded rod 2
It is vertically connected on axis, and the maximum distance that augers 8 moves up is 8 lower end of augers and probe tube horizontal cross-section
Concordantly, the maximum distance that augers 8 moves down is that 8 upper end of augers is concordant with probe tube horizontal cross-section.
Three support rods 4 are additionally provided on the outside of sampler barrel main body 3, it is equal that three support rods 4 are located at 3 outer circumference surface of sampler barrel main body
Even distribution, the bottom of every support rod 4 connect downwards triangular pyramid earth anchor 6.
The outer wall of sampler barrel main body 3 is equipped with otic placode 5, and otic placode 5 is equipped with axis hole, and one end of support rod 4 is equipped with and otic placode 5
The corresponding through-hole in axis hole position, otic placode 5 are connect with support rod 4 by bolt 9, and the nut on bolt 9 is wing nut.
Working principle: the bolt 9 connected between tune pine sampler barrel main body 3 and support rod 4 when use, by sampler barrel main body 3
The laciniation of lower end is overlapped positioning with the sample point of selection, while in the earth anchor insertion soil of 4 lower end of support rod, then locks
The triangular support configurations that bolt 9 consolidates support rod 4, sampler barrel main body 3 and ground composition, the square joint 1 of 2 upper end of threaded rod
With torque spanner or the electric drill with interface is connect, and driving threaded rod 2 rotates, and moves downward augers 8 with screw rod, and
It rotates into inside roadbed, the soil sample that the rotation chisel of augers 8 takes is expelled in sampling bag or other containers by sample outlet pipe 7 to be received
Collection.
This is practical in road bed aperture and to extract soil sample, then is discharged directly in container by sample outlet pipe 7, solve
It needs to dig out soil sample in sampling using the tedious steps for taking collection are manually swept before having determined, so that operation is more convenient, mention
High working efficiency, while the safety problem for the easy initiation that soil sample is splashed in sampling is also avoided, in 3 lower end of sampler barrel main body
The laciniation used for positioning of design, it is more convenient to be positioned on sample point, and in the earth anchor of 4 bottom of support rod installation
6, the triangular support configurations for consolidating support rod 4, sampler barrel main body 3 and ground composition effectively avoid in sampling process
The problem of sampler barrel main body 3 is subjected to displacement makes the utility model more accurate, augers 8 in needing fixed point location sampling
