Abstract

The utility model relates to a kind of spring thief rod of soil sampler, comprise the body of rod, the upper end of the body of rod is with control stick, its lower end is with the cover that fetches earth, described lower end of fetching earth cover is 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 cross section of the spring wire of spring housing is parallelogram sturcutre, and the central axis of its relative spring housing is obliquely installed: the upper end opposing lower end in the cross section of spring wire is to the central reduction of spring housing; The lower end of spring housing is fixed with and drills through cover.The utility model, compared with traditional bar that fetches earth, connects volute spring cover in the lower end of the cover that fetches earth and drills through cover, improving the driving power of sampling on the one hand, improving the adhesive force of soil sample on the other hand, thus improving sampling reliability and efficiency.

Description

The spring thief rod of soil sampler
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 shortcoming of the prior art, carries out studying and improving, and provides a kind of spring thief rod of rational in infrastructure, easy to use, soil sampler that efficiency is high.
The technical scheme that the utility model adopts is as follows:
A spring thief rod for soil sampler, comprises the body of rod, and 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 cross section of the spring wire of spring housing is parallelogram sturcutre, and the central axis of its relative spring housing is obliquely installed: the upper end opposing lower end in the cross section of spring wire is to the central reduction of spring housing; The lower end of spring housing is fixed with and drills through cover.
Further improvement as technique scheme:
Described compact part increases progressively to the spacing of the spring wire of part of rarefaction.
The lateral surface of described spring wire and medial surface respectively with the centerline axis parallel of spring housing.
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 and drills through cover, improving the driving power of sampling on the one hand, improving the adhesive force of soil sample on the other hand, thus improving 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.
Fig. 3 is partial sectional view of the present utility model.
Wherein: 1, the body of rod; 2, fetch earth cover; 3, spring housing; 30, spring wire; 31, compact part; 32, part of rarefaction; 4, control stick; 5, cover is drilled through.
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, Figure 2 and Figure 3, the spring thief rod of the soil sampler 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; The cross section of the spring wire 30 of spring housing 3 is parallelogram sturcutre, compares coil component spring silk, is more conducive to the attachment of soil sample; The central axis of the relative spring housing 3 of spring wire 30 is obliquely installed: the upper end opposing lower end in the cross section of spring wire 30 to the central reduction of spring housing 3, namely in Eight characters structure; The lower end of spring housing 3 is fixed with and drills through cover 5, drills through cover 5 and is made up of high strength material, and it is thin-wall construction, for drilling through fast, improves sample rate.
As shown in Figure 2, the spacing of the spring wire of compact part 31 to part of rarefaction 32 increases progressively, the lateral surface of spring wire 30 and medial surface respectively with the centerline axis parallel of spring housing 3.
The utility model has the advantage of: compact part 31 is positioned at lower end, its intensity and rigidity higher, and drill through cover 5 and combine, realize speedy drivage sub-terrain operations; Part of rarefaction 32 is positioned at upper end, and after sampling, soil sample can be absorbed in in adjacent spring wire 30, and spring wire 30 is obliquely installed, and is beneficial to soil sample and enters in the gap of spring wire 30, improves the adhesive force 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 and drills through cover, improving the driving power of sampling on the one hand, improving the adhesive force of soil sample on the other hand, thus improving 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.
