Abstract
The utility model relates to a kind of bar structure that fetches earth of soil sampler, comprises the bar body that fetches earth, and the bar body that fetches earth comprises the screw mandrel on top and the cover that fetches earth of bottom, the upper end band jug of screw mandrel, described in fetch earth cover lower end be connected with taper sheath.The utility model, compared with traditional bar that fetches earth, connects taper sheath in the lower end of the cover that fetches earth, and avoids soil sample to depart from the cover that fetches earth, realizes primary sample, improve sampling efficiency.
Description
Technical field
The utility model relates to geological prospecting apparatus field, particularly relates to a kind of soil sampler.
Background technology
In geological exploration field, gather earth sample and often commonly use soil sampler.Existing sampler structure comprises annular base, the center of base is fixed with guide holder, and the central slide device of guide holder fetches earth bar, and the bar that fetches earth is that upper end is with the structure of screw mandrel lower end with the cover that fetches earth, screw mandrel spiral is connected in screw rodb base, and screw rodb base is fixedly connected with annular base.The shortcoming that the bar that fetches earth of the soil sampler of said structure exists is: the lower end of the bar that fetches earth is tubular assembling structure, and when departing from ground after fetching earth, earth sample easily comes off in cylinder, and cause needing repeatedly to fetch earth, efficiency is low.
Utility model content
The applicant, for above-mentioned existing shortcoming of the prior art, carries out studying and improving, and provides a kind of bar structure that fetches earth of rational in infrastructure, easy to use, soil sampler that efficiency is high.
The technical scheme that the utility model adopts is as follows:
The bar structure that fetches earth of soil sampler, comprises the bar body that fetches earth, and the bar body that fetches earth comprises the screw mandrel on top and the cover that fetches earth of bottom, the upper end band jug of screw mandrel, described in fetch earth cover lower end be connected with taper sheath.
Further improvement as technique scheme:
The bottom diameter of described taper sheath is less than the internal diameter of the cover that fetches earth.
Described taper sheath is volute spring.
The spring wire cross section of described volute spring is rectangular configuration.
The two ends of described handle are respectively with through hole.
The beneficial effects of the utility model are as follows:
The utility model, compared with traditional bar that fetches earth, connects taper sheath in the lower end of the cover that fetches earth, and avoids soil sample to depart from the cover that fetches earth, realizes primary sample, improve sampling efficiency; Structure of the present utility model is simple, reasonable in design.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Wherein: 1, screw mandrel; 2, fetch earth cover; 3, taper sheath; 4, handle; 41, through hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, the bar structure that fetches earth of the soil sampler of the present embodiment, comprises the bar body that fetches earth, and the bar body that fetches earth comprises the screw mandrel 1 on top and the cover 2 that fetches earth of bottom, the upper end band jug 4 of screw mandrel 1, the two ends of handle 4 respectively with through hole 41, to facilitate operation by human hand.The fetch earth lower end of cover 2 is connected with taper sheath 3, and taper sheath 3 welds together with the cover 2 that fetches earth, and the bottom diameter of taper sheath 3 is less than the internal diameter of the cover 2 that fetches earth.
Taper sheath 3 can be common conical ring structure, but is preferably the volute spring structure in Fig. 1, and for avoiding soil sample to come off, the spring wire cross section of volute spring is preferably set to rectangular configuration.
The utility model, compared with traditional bar that fetches earth, connects taper sheath in the lower end of the cover that fetches earth, and avoids soil sample to depart from the cover that fetches earth, realizes primary sample, improve sampling efficiency.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
