Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
As Figure 1-3, mark 1-23 in figure to be expressed as: compression end 1, sampling body 2, driving end 3, force transmission ring 4, rigidity outer shroud 5, inner lining body 6, sampling skin 7, ball 8, bolt 9, pointed cone 10, baffle ring 11, turning handle 12, rotating shaft 13, rotation hole 14, rotating disk 15, initiative exhaust hole 16, passive vent port 17, set collar 18, handle 19, force side 20, cavity 21, sampling import 22, the sampler space 23.
Embodiment: as depicted in figs. 1 and 2, the prospect pit sampler in the present embodiment comprises compression end 1, sampling body 2, driving end 3 three part.Sampling body 2 is made up of rigidity outer shroud 5 and inner lining body 6.The bottom of rigidity outer shroud 5 offers cavity 21, and inner lining body 6 is sleeved among cavity 21.Clamp ball 8 between the both sides inwall of inner lining body 6 and rigidity outer shroud 5, made to form between the inwall of inner lining body 6 and rigidity outer shroud 5 to be slidably matched, namely made inner lining body 6 can slide among the cavity 21 of rigidity outer shroud 5 and skid off.Compression end 1 is fixed on the top surface of rigidity outer shroud by force transmission ring 4, and pressure can be passed on the rigidity outer shroud 5 outside sampling body 2 by compression end 1 and force transmission ring 4 by force side 20 successively, thus the press-in of finishing device.Rigidity outer shroud 5 end face has set collar 18, and set collar 18 is suitable with force transmission ring 4 size, is convenient to pressure uniform transmission.Between compression end 1 and force transmission ring 4, detachable being connected and fixed is set, realizes disassembled and assembled freely between the two, pick and place.
As shown in figures 1 and 3, in rigidity outer shroud, 5 sides are distributed with inner lining body 6, and inner lining body 6 drives the sampling skin 7 turnover rigidity outer shroud 5 automatically inside it by ball 8.The region that sampling skin 7 surrounds is the sampler space 23.Ball 8 sections bottom is fixed with bolt 9 near the outer ledge of inner lining body 6, will tunnel end 3 and be fixedly mounted on the bottom of the inner lining body 6 sampling body 2 by the threaded engagement between baffle ring 11 inner screw channel at pointed cone 10 top and bolt 9; After the baffle ring 11 at pointed cone 10 top tightens with bolt 9, baffle ring 11 is adjacent on the open end of the cavity 21 of rigidity outer shroud 5, thus hold out against the inner lining body 6 being positioned at cavity 21, prevent inner lining body 6 moving freely in cavity 21, ensure the stability of sampling body 2.Sample import 22 by pointed cone 10 and baffle ring 11 offer, sampling import 22 is connected with the sampler space 23, and soil sample enters from sampling import 22 and tunnels end 3, is kept at afterwards and samples among the sampler space 23 that skin 7 surrounds.
Sampling body 2 top is provided with turning handle 12, the rotation hole 14 that turning handle 12 passes through rigidity outer shroud 5 end face by rotating shaft 13 is connected with rotating disk 15, rotating disk 15 is distributed with three initiative exhaust holes 16, the end face of inner lining body 6 and the correspondence position in initiative exhaust hole 16 are distributed with three passive vent ports 17.When device is in tunneling process, by turning handle 12, by initiative exhaust hole 16 and the corresponding formation conducting in passive vent port 17 position, make soil sample enter the additional air can getting rid of inner lining body 6 tip position in inner lining body 6 process, be convenient to driving.When soil sample driving is complete, regulating rotary fixed handle 12, makes initiative exhaust hole 16 and passive vent port 17 position stagger, thus to ensure in sampling body 2 between soil sample and inner lining body 6 without excessive gas, be convenient to the taking-up of device and the integrality of soil sample, avoid soil sample to loosen and be scattered in inner lining body 6.Rigidity outer shroud 5 top is fixedly installed some handles 19, is convenient to technician and applies pulling force withdrawing device from the soil body.
The present embodiment is in the specific implementation: rigidity outer shroud 5, handle 19, compression end 1, force transmission ring 4, pointed cone 10 etc. should adopt clean steel technological forming, the resistance to overturning of assurance device.The available quality such as inner lining body 6, turning handle 12, rotating disk 15 are comparatively light, be easy to shaping and have the plastics of certain rigidity or other compound substance makes.The setting of the active and passive venthole at turning handle 12, rotating disk 15 and inner lining body 6 top, the grinding tool type that also generally can use according to market, selects other shape, just can with the using function not affecting associated components.Pressure applies, the existing force method such as can adopt lifting jack, manpower is compressed into, can according to soil sample character optimum selecting, and pressure applies not within the limit of consideration of this device.Sampling skin 7 can adopt iron sheet or other material making being easy to shaping, having certain plasticity, can reuse.Ball 8 between inner lining body 6 and rigidity outer shroud 5, can adopt the existing technological improvement in market to use.
The present embodiment, when concrete operations, carries out according to the following steps:
1, sampling skin 7 is placed in inner lining body 6, then inner lining body 6 is put into rigidity outer shroud 5 by rolling steel ball 8, afterwards pointed cone 10 and baffle ring 11 are connected on bolt 9, make grade ring 11 hold out against inner lining body 6.
2, regulating rotary fixed handle 12, makes that the initiative exhaust hole 16 on rotating disk 15 is corresponding with passive vent port 17 position on inner lining body 6 forms conducting.
3, sampling body 2 and driving end 3 are placed the position that need sample, operating personnel one people stationary installation, compression end 1 and force transmission ring 4 are placed in rigidity outer shroud top set collar 18 by another people, and then apply pressure, device is progressed in the soil body.Now, soil sample enters among the sampler space 23 of sampling skin 7 from the sampling import 22 of driving end 3.
4, after being filled with soil sample in the sampler space 23 of sampling skin 7, compression end 1 and force transmission ring 4 is removed from set collar 18 dismounting, regulating rotary fixed handle 12 again, makes the initiative exhaust hole 16 on rotating disk 15 be formed closed with passive vent port 17 location dislocation on inner lining body 6.
5, by the handle 19 at rigidity outer shroud 5 top, fine rotation device, subsequently slowly withdrawing device from the soil body.Unload the driving pointed cone 10 of end 3 and baffle ring 11, from the cavity 21 of rigidity outer shroud 5, take out inner lining body 6 by ball 8, and then take out sampling skin 7 and soil sample from inner lining body 6, seal up for safekeeping and completely deliver to testing laboratory.
6, repeat step 1-5, carry out the sampling work of other one group.
Although above embodiment elaborates the design of the utility model object and embodiment with reference to accompanying drawing, but those of ordinary skill in the art can recognize, under the precondition not departing from claim limited range, still various improvement and conversion can be made to the utility model, as the specific constructive form etc. of: the version of active and passive vent port and distributing position, force side 20, therefore do not repeat one by one at this.
