Abstract
The one that relates to the utility model fetches earth bar structure, and comprise the body of rod, the upper end of the body of rod is with control stick, its lower end with the cover that fetches earth, described in fetch earth cover lower end be connected with volute spring cover, the taper contraction structure that spring housing is large with upper end, lower end is little, its upper end is part of rarefaction, and lower end is compact part.The utility model, compared with traditional bar that fetches earth, connects volute spring cover in the lower end of the cover that fetches earth, improves the driving power of sampling on the one hand, improve the adhesive power of soil sample on the other hand, thus improve sampling reliability and 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 above-mentioned soil sampler exists is: the lower end of the bar that fetches earth is barrel shape 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; And the driving power during sampling of the lower end of tubular construction is not enough, and the time that primary sample expends is longer.
Utility model content
The applicant, for above-mentioned existing shortcoming of the prior art, carries out studying and improving, and provides a kind of rational in infrastructure, easy to use, bar structure that fetches earth that efficiency is high.
The technical scheme that the utility model adopts is as follows:
One fetches earth bar structure, comprises the body of rod, the upper end of the body of rod with control stick, its lower end with the cover that fetches earth, described in the fetch earth lower end of cover be connected with volute spring cover, the taper contraction structure that spring housing is large with upper end, lower end is little, its upper end is part of rarefaction, and lower end is compact part.
Further improvement as technique scheme:
Described compact part increases progressively to the spacing of the spring wire of part of rarefaction.
The cross section of the spring wire of described spring housing is rectangle.
The beneficial effects of the utility model are as follows:
The utility model, compared with traditional bar that fetches earth, connects volute spring cover in the lower end of the cover that fetches earth, improves the driving power of sampling on the one hand, improve the adhesive power of soil sample on the other hand, thus improve sampling reliability and efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
Wherein: 1, the body of rod; 2, fetch earth cover; 3, spring housing; 31, compact part; 32, part of rarefaction; 4, control stick.
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 and Figure 2, the bar structure that fetches earth of the present embodiment, comprise the body of rod 1, the upper end of the body of rod 1 is with control stick 4, its lower end is with the cover 2 that fetches earth, and the lower end of the cover 2 that fetches earth is connected with volute spring cover 3, the taper contraction structure that spring housing 3 is large with upper end, lower end is little, its upper end is part of rarefaction 32, and lower end is compact part 31.
As shown in Figure 2, the spacing of the spring wire of compact part 31 to part of rarefaction 32 increases progressively, and the cross section of the spring wire of spring housing 3 is rectangle, and coil component spring silk compared by Rectangular Spring silk, is more conducive to the attachment of soil sample.
The advantage of this structure is: compact part 31 is positioned at lower end, its intensity and rigidity higher, driving underground when being easy to sampling, part of rarefaction 32 is positioned at upper end, and after sampling, soil sample can be absorbed in in adjacent spring wire, improves the adhesive power of soil sample.
The utility model, compared with traditional bar that fetches earth, connects volute spring cover in the lower end of the cover that fetches earth, improves the driving power of sampling on the one hand, improve the adhesive power of soil sample on the other hand, thus improve sampling reliability and 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.
