101 and the second sampling part 102 when docking, first hollow cylinder 6 and second hollow cylinder 601 are located at always
It on line and mutually staggers, while gapless between adjacent first hollow cylinder 6 and second hollow cylinder 601, two spiral shells
Nail 7 sequentially passes through first hollow cylinder, 6 and second hollow cylinder 601 on same vertical direction, the screw 7 one
End is equipped with fixture block 701, and the cross section of the fixture block 701 is more than in first hollow cylinder 6 or second hollow cylinder 601
The cross section of diameter, but no more than the cross section of first hollow cylinder 6 or 601 outer diameter of the second hollow cylinder, the spiral shell
It follows closely 7 other ends and sequentially passes through several first hollow cylinders 6 on same vertical direction and second hollow cylinder
601 rear threads are connected to the precession Guan Shangjie 201, thus can sample part 101 and the second sampling part 102 by described first
The columnar probe tube 1 of annulus is formed, keeps the smooth of 1 outer surface of probe tube, and be screwed on the precession pipe
Upper section 201.The top and bottom of the probe tube 1 can be threaded connection with a bottom cover 19, after being sampled for probe tube 1 to top and
Bottom seal, in this way after obtaining sample, it is ensured that the soil sample structure adopted does not change, while being conducive to again by soil sample band
After going back to laboratory, need to only open probe tube 1 smoothly can be transferred to earth pillar device by soil sample or be studied for other.
The present apparatus before use, the circular hole among the circular hole at the middle part of connecting rod 10 and handle 9 is aligned by the first step, is being used in combination the
One locking pin 12 fixes the two；Second step will be in the alignment connecting rod 10 of cylinder containing internal thread of 8 bottom of sampler trim ring
Turn after the external screw thread of end, realizes the threaded connection of the two；Third step connecting rod 10 is inserted into consolidating for 201 tops precession Guan Shangjie
After fixed column, with second locking pin 12 across the after the first circular hole of fixed column and the second circular hole of connecting rod 10 are overlapped
One circular hole and the second circular hole are fixed, and realize the connection of connecting rod 10 and precession Guan Shangjie 201；4th step is by hinge connection
Screw 7 passes through the hinge connection of the first hollow cylinder 6 and the second hollow cylinder 601 two semicolumn blocks of realization of hinge connection,
Then it is threaded io in precession Guan Shangjie 201, that is, realizes the connection of probe tube 1 and precession Guan Shangjie 201；5th step will
Section 202 entangles probe tube 1 under precession pipe, then up the bolt 17 being fixed in the lower section bolt clip for saving 202 under precession pipe
It turns over, the upper end of nut 18 is made to enter in the upper section bolt clip on 201 edges precession Guan Shangjie, then use wing nut 18 by spiral shell
Bolt 17 is fixed under precession Guan Shangjie 201 and precession pipe in the bolt clip of section 202 so that the section up and down of precession pipe 2 is connected.
Carry out section 202 under sampler trim ring 8, sampler handle 9, connecting rod 10, precession Guan Shangjie 201, precession pipe, sampling
After the connection work of pipe 1, the soil surface that sampler is sampled perpendicular to needs a, human hand holds sampler trim ring 8, two people difference
The both ends of sampler handle 9 are held, then three people make power and rotate in one direction simultaneously, make 202 rotation of section under entire precession pipe
Into in soil, as pressure increases, soil is squeezed into probe tube 1, and air therein is extruded with gas vent.By observing precession
After the scale slot 5 of section 202 confirms that section 202 has arrived at the depth of soil of required sampled point under precession pipe under pipe, stopping makes power, by
Wing nut 18 is unscrewed, and so that precession pipe is saved up and down and is not reconnected, then slightly rotation sampler handle 9, by probe tube 1 from precession
It is extracted in section 202 under pipe, i.e., probe tube 1 leaves the soil body.Sampler not with section 202 under precession pipe is lain against into clean ground
After upper, with the bottom of the corresponding 19 precession probe tube 1 of bottom cover of probe tube, realize bottom seal, then invert precession Guan Shangjie
201, so that probe tube 1 is detached with precession Guan Shangjie 201, then will be sealed at the top of probe tube with the bottom cover 19 of corresponding probe tube 1,
And carry out bearing mark on the outer wall of probe tube 1.Section 202 under precession pipe is firmly slightly finally extracted into the soil body.When to next
It when a sampled point, is sampled with new probe tube 1, sampling method is the same with the first sub-sampling.
After acquiring sample, the probe tube 1 that soil sample is housed one by one is brought back in laboratory, it can be according to experiment
Purpose and demand open the probe tube 1 connected with hinge-type connection type, and soil sample is transferred to earth pillar device, carries out earth pillar
Experimental study knows the soil layering sample of different depth also according to the graduated scale on probe tube 1, for other researchs.Soil sample
Probe tube 1 is cleaned up after taking-up, in case next time uses.
Embodiment two
It please refers to Fig.4 and Fig. 5, embodiment of the invention discloses that a kind of portable screw type original-state soil sampler, with
Difference lies in the mounting means of probe tube 1 for a kind of structure of portable screw type original-state soil sampler disclosed in embodiment one
Difference, 7 one end of the screw are equipped with fixture block 701, and the cross section of the fixture block 701 is more than first hollow cylinder 6 or described
The cross section of second hollow cylinder, 601 internal diameter, and be not more than outside first hollow cylinder 6 or second hollow cylinder 601
The cross section of diameter, 7 other end of the screw sequentially pass through several 6 Hes of the first hollow cylinder on same vertical direction
Second hollow cylinder, 601 rear thread installs a fastening nut 702, and described take is completed by tightening the fastening nut 702
The splicing of sample pipe 1 is installed, and also globality is more preferably when the follow-up probe tube 1 takes back sample.1 top of the probe tube passes through described
201 bottoms precession Guan Shangjie are connect with 201 inner threads of precession Guan Shangjie, thus may be implemented the probe tube 1 with
