in the design of great Foundation Design architecture construction (as power station, harbour, marine drilling platform, highrise building etc.), and when broken formation is taken a sample (gravel mine etc.), required very high to getting formation sample, and traditional core method of getting is perplexing the sampling quality of soil layer and sandy gravel stratum always, as shown in Figure 1, Fig. 1 is that traditional rock sample adopts the structural representation of mechanism, it comprises outer tube 10, the end of described outer tube 10 has been threaded connection drill bit 11, and be provided with basket 12 in described outer tube 10, the upper end of described basket 12 connecting short sections 13, the lower end of described end joint 13 is provided with jump ring 14 and clip spring seat 15.When bulk sample is sampled, there is following shortcoming in the rock sample sampling mechanism of this kind structure:
1) because the vibration in drilling process, sample enter stirring in process, sand sample is mixed sample easily, does not reach the purpose that drills through original state sample;
The bulk sample that drills through while 2) creeping into directly enters the piperock core barrel, because the sample that enters in basket pushes mutually, sample is jammed in basket, be difficult for taking out in basket, often by percussion vibration, withdraw from sample, this method both wasted time and energy, and the sample of taking-up likely scatters again, mixed sample phenomenon often occurred; Do not reach the purpose of true reflection geological condition.
The utility model content
The purpose of this utility model is to provide a kind of rock sample auto-filling sampling mechanism, and it in sampling process, mixed sample can not occur, truly reflects geological condition, to solve the problem that in prior art, the rock sample sample devices exists.
For reaching this purpose, the utility model by the following technical solutions:
A kind of rock sample auto-filling sampling mechanism, it comprises outer pipe assembly, basket, inner tube assembly and drill bit, wherein, described inner tube assembly comprises inside and outside cover, rock sample bag and piston, the upper end of described overcoat connects basket, described inner sleeve is arranged in overcoat and has the gap of accommodating rock sample bag between the two, described piston can be arranged in overcoat up or down, and the lower end of described piston connects inner sleeve, the lower end of described inside and outside cover connects by link, and the upper end of described rock sample bag is fixed on piston.
Especially, described link comprises clip spring seat and jump ring, and the lower end of described inside and outside cover is the Connection Card spring abutment together, on described clip spring seat, jump ring is set.
Especially, offer through hole on described piston, so that pressure release and draining.
Especially, be provided for spacing step and seam between described inside and outside cover, and described step separates inside and outside cover to form described gap.
Especially, offer circumferential groove on described piston, the upper end of described rock sample bag is stuck in circumferential groove and is fixed.
Especially, described rock sample bag is polybag.
The beneficial effects of the utility model are, compared with prior art described rock sample auto-filling sampling mechanism is in the geological drilling process, the sample that drills through arrives piston position by drill bit, jump ring successively, pushing piston is up, piston driving rock sample bag moves upward, to enter so the interior sample auto-filling of basket in the rock sample bag, not only avoid the generation of the mixed sample of sample, truly reflect geological condition; And protect simultaneously the sample that has taken out, be convenient to the sample transportation and preserve.
Description of drawings
Fig. 1 is that traditional rock sample adopts the structural representation of mechanism;
Fig. 2 is the sectional drawing of the rock sample auto-filling sampling mechanism that provides of the utility model specific embodiment 1;
Fig. 3 is the partial enlarged drawing at A place in Fig. 2;
Fig. 4 is the partial enlarged drawing at B place in Fig. 2.
The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
see also Fig. 2 and shown in Figure 4, in the present embodiment, a kind of rock sample auto-filling sampling mechanism comprises outer pipe assembly 20, basket 21, inner tube assembly and drill bit 22, described inner tube assembly comprises inner sleeve 23 and overcoat 24, rock sample bag 25 and piston 26, the upper end of described overcoat 24 connects basket 21, described inner sleeve 23 is arranged in overcoat 24 and has the gap 27 of accommodating rock sample bag 25 between the two, described piston 26 can be arranged in overcoat 24 up or down, and the lower end of described piston 26 connects inner sleeve 23, connection is connected by clip spring seat 28 in the lower end that described inner sleeve 23 is connected with overcoat with jump ring, offer circumferential groove 30 on described piston 26, the upper end of described rock sample bag 25 is stuck in circumferential groove 30 to be fixed on piston 26.
