Efficient soil samplerThe application is application number 2014106659741,19 days November 2014 applying date, denomination of invention " efficient soil sampler "Divisional application.
Technical field
The present invention relates to geological prospecting apparatus field more particularly to a kind of soil samplers.
Background technology
In geological exploration field, acquisition earth sample commonly uses soil sampler often.Existing sampler structure includes annulusShape pedestal, the center of pedestal are 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 carries lead screwLower end carries the structure of fetch earth set, and lead screw spiral is connected in screw rodb base, and screw rodb base is fixedly connected with circular ring shape base.Soil samplerIt has the drawback that：Fetch earth bar lower end be tubular assembling structure, after fetching earth be detached from ground when, earth sample be easy falls off out of cylinder,It results in the need for repeatedly fetching earth, efficiency is low.
Invention content
The applicant for the above-mentioned prior art in disadvantage, studied and improved, provided a kind of reasonable for structure, convenientlyUse the high efficient soil sampler of, soil extracting efficiency.
The technical solution adopted in the present invention is as follows：
The center of a kind of efficient soil sampler, including circular ring shape base, pedestal is fixed with guide holder by connecting plate, guide holderCentral slide device fetches earth bar, and the bar that fetches earth is the structure that upper end carries fetch earth set with screw lower end, and lead screw spiral is connected to silkIn pole socket, screw rodb base is fixedly connected with circular ring shape base by more fixed links, and the upper end of lead screw carries handle, the fetch earth setLower end be connected with taper sheath.
As a further improvement of the above technical scheme：
The bottom diameter of the taper sheath is less than the internal diameter of fetch earth set.
The taper sheath is volute spring, the spring wire rectangular cross-section structure of the volute spring.
The lower surface of the pedestal carries first annular flange.
The both ends of the handle are respectively provided with through-hole.
The both ends of the connecting plate carry multiple rows of mounting hole, and the end of connecting plate is inserted in the periphery mounting groove of pedestal, pedestalThe upper locking hole with the perforation mounting groove.
The lower surface of the guide holder carries the second annular flange.
Beneficial effects of the present invention are as follows：
The simple structure and reasonable design of the present invention；Taper sheath is connected in the lower end of fetch earth set, soil sample disengaging is avoided to fetch earthSet realizes primary sample, improves sampling efficiency；The simple structure and reasonable design of the present invention.

Specific implementation mode
Below in conjunction with the accompanying drawings, illustrate the specific implementation mode of the present invention.
As shown in Figure 1, the efficient soil sampler of the present embodiment, including circular ring shape base 1, the center of pedestal 1 are solid by connecting plate 6It is connected with guide holder 2, the central slide device of guide holder 2 fetches earth bar 4, and the bar 4 that fetches earth is upper end with 41 lower end of lead screw with fetching earthThe structure of set 42,41 spiral of lead screw are connected in screw rodb base 3, and screw rodb base 3 is fixed with circular ring shape base 1 by more fixed links 5The upper end of connection, lead screw 41 carries handle 44, and the lower end of fetch earth set 42 is connected with taper sheath 43.
As shown in Fig. 2, the lower surface of guide holder 2 carries the second annular flange 21.
As shown in Figure 1, the lower surface of pedestal 1 carries first annular flange 12.
As shown in figure 3, the lower end of fetch earth set 42 is connected with taper sheath 43, the bottom diameter of taper sheath 43 is less than fetch earth set 42Internal diameter, taper sheath 43 be volute spring, the spring wire rectangular cross-section structure of volute spring；The both ends of handle 44 are respectively provided withThrough-hole 441, through-hole 441 facilitate operation by human hand handle 44.
As shown in Figure 1, the both ends of connecting plate 6 carry multiple rows of mounting hole 61, the end of connecting plate 6 is inserted in the periphery peace of pedestal 1In tankage 11, the locking hole 13 with perforation mounting groove 11 on pedestal 1, installation operation is convenient between connecting plate 6 and pedestal 1, connectionFirm, clipping room is adjusted away from realizing the connection between different size of guide holder 2 and pedestal 1 in multiple rows of mounting hole 61.
The present invention is in use, pedestal 1 is contacted with ground；Fetch earth set 42 is screwed in underground by swing handle 44, during screw-in,The first annular flange 12 of 1 lower surface of pedestal is inserted into underground, prevents it from handle 44 being followed to rotate；The taper sheath of 42 lower end of fetch earth set43 one side can reduce the resistance between fetch earth set 42 and ground, on the other hand can fall off to avoid sample when retracting, toRealize primary sample, it is efficient.
The simple structure and reasonable design of the present invention；Taper sheath is connected in the lower end of fetch earth set, soil sample disengaging is avoided to fetch earthSet realizes primary sample, improves sampling efficiency；The simple structure and reasonable design of the present invention.
Above description is explanation of the invention, is not the restriction to invention, limited range of the present invention is referring to rightIt is required that within protection scope of the present invention, any type of modification can be made.
