Abstract

The invention relates to a spring type sampling rod for a soil sampler. The spring type sampling rod comprises a rod body, wherein an operation rod is arranged at the upper end of the rod body, and a soil sampling sleeve is arranged at the lower end of the rod body; a cone-shaped spring sleeve is connected to the lower end of the soil sampling sleeve and is provided with a cone-shaped shrinking structure, the upper end of the cone-shaped shrinking structure is big thin part, and the lower end of the cone-shaped shrinking structure is small thick part; the section of a spring wire of the spring sleeve is of a parallelogram and is obliquely arranged relative to the central axis of the spring sleeve; the upper end of the section of the spring wire shrinks towards the center of the spring sleeve in a manner of being relative to the lower end of the section of the spring wire; a drilling sleeve is fixedly connected to the lower end of the spring sleeve. Compared with a traditional soil sampling rod, the spring type sampling rod has the advantages that the cone-shaped spring sleeve and the drilling sleeve are connected to the lower end of the soil sampling sleeve, so that on one hand, tunneling force of sampling is increased, on the other hand, adhesive force of a soil sample is increased, and the sampling reliability and efficiency are improved.

Description

The spring thief rod of soil sample barrel
Technical field
The present invention relates to geologic prospecting apparatus field, particularly relate to a kind of soil sample barrel.
Background technology
In geological exploration field, gather earth sample and often commonly use soil sample barrel.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 sample barrel 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.
Summary of the invention
The applicant, for above-mentioned existing 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 sample barrel that efficiency is high.
The technical solution adopted in the present invention is as follows:
A spring thief rod for soil sample barrel, comprises the body of rod, and the upper end of the body of rod is with operating rod, 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.
Beneficial effect of the present invention is as follows:
The present invention, 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 adhesion of soil sample on the other hand, thus improving sampling reliability and efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
Fig. 3 is partial sectional view of the present invention.
Wherein: 1, the body of rod; 2, fetch earth cover; 3, spring housing; 30, spring wire; 31, compact part; 32, part of rarefaction; 4, operating rod; 5, cover is drilled through.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the spring thief rod of the soil sample barrel of the present embodiment, comprise the body of rod 1, the upper end of the body of rod 1 is with operating rod 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 invention has the advantages that: 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 adhesion of soil sample.
The present invention, 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 adhesion of soil sample on the other hand, thus improving sampling reliability and efficiency.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
