Inclined soil sampler
Technical field
The present invention relates to geological prospecting apparatus field, more particularly, to a kind of soil sampler.
Background technology
In geological exploration field, collection earth sample commonly uses soil sampler often.Existing sampler structure includes 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 carries, for upper end, the structure that screw mandrel lower end carries the set that fetches earth, screw mandrel spiral is connected in screw rodb base, and screw rodb base is fixedly connected with annular base.Above-mentioned soil sampler has the drawback that:Fetch earth bar lower end be barrel shape structure, after fetching earth depart from ground when, earth sample easily comes off in cylinder, results in the need for repeatedly fetching earth, efficiency is low;Soil sampler can only relatively vertically fetch earth on ground, or can be slightly slanted and fetch earth, and is not suitable for the soil sample that there is solid bed to top, sampling operation is difficult.
Content of the invention
The applicant is directed to above-mentioned existing shortcoming of the prior art, is studied and improves, provide a kind of rational in infrastructure, soil extracting efficiency is high, be easy to tilt the inclined soil sampler fetching earth.
The technical solution adopted in the present invention is as follows:
A kind of inclined soil sampler, including base, on base, device fetches earth bar, the bar that fetches earth carries, for upper end, the structure that screw mandrel lower end carries the set that fetches earth, and screw mandrel spiral is connected in screw rodb base, and screw rodb base is fixedly connected with base, described base includes base plate, plate upper surface is connected front vertical plate and back vertical plate, front vertical plate has fairlead with carrying axially consistent inclined via-hole, the front side device of front vertical plate on back vertical plate, and the central through hole of fairlead is axially coincident with described inclined via-hole;Described screw rodb base is fixed on the rear side of back vertical plate, and screw rodb base carries the screw hole of central shaft and the center overlapping of axles of described inclined via-hole, and screw hole is connected with screw mandrel cooperation spiral, fetches earth and be placed in fairlead;The lower end of the described set that fetches earth is connected with taper sheath, and the outer wall of the set that fetches earth is fixed with and drills through headgear.
Improvement further as technique scheme:
The bottom diameter of described taper sheath is less than the internal diameter of the set that fetches earth.
Described taper sheath is volute spring, the spring wire rectangular cross-section structure of described volute spring.
External screw thread is carried, the upper end inwall drilling through headgear carries the internal thread with the cooperation of described external screw thread outside the lower end of the described set that fetches earth.
Described drill through on headgear carry its side wall of insertion locking through hole.
The described upper end outer wall drilling through headgear carries upper arcuate guide anchor ring, and its lower end outer wall carries arc lower and guides anchor ring.
The connecting portion of described front vertical plate, back vertical plate and base plate is respectively provided with reinforcement gusset.
Beneficial effects of the present invention are as follows:
The structure of the present invention is simple, reasonable in design;The base of setting incline structure, is easy to inclination and fetches earth sample;Connect taper sheath in the lower end of the set that fetches earth, it is to avoid soil sample departs from the set that fetches earth, realize primary sample, improve sampling efficiency, the outer wall of taper sheath is equipped with the native headgear of brill, realizes protecting and improving sampling efficiency to taper sheath.

Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, the inclined soil sampler of the present embodiment, including base, on base, device fetches earth bar 4, the bar 4 that fetches earth carries, for upper end, the structure that screw mandrel 41 lower end carries the set 42 that fetches earth, screw mandrel 41 spiral is connected in screw rodb base 7, screw rodb base 7 is fixedly connected with base, base includes base plate 5, front vertical plate 1 and back vertical plate 2 that base plate 5 upper surface is connected, front vertical plate 1, back vertical plate 2 is respectively provided with reinforcement gusset 6 with the connecting portion of base plate 5, front vertical plate 1 with axially consistent inclined via-hole 8 is carried on back vertical plate 2, the front side device of front vertical plate 1 has fairlead 3, the central through hole of fairlead 3 is axially coincident with inclined via-hole 8;Screw rodb base 7 is fixed on the rear side of back vertical plate 2, and screw rodb base 7 carries the screw hole of central shaft and the center overlapping of axles of inclined via-hole 8, and screw hole is connected with screw mandrel 41 cooperation spiral, and the set 42 that fetches earth is placed in fairlead 3;The fetch earth lower end of set 42 is connected with taper sheath 43, and the outer wall of the set 42 that fetches earth is fixed with and drills through headgear 44, drills through the upper and lower ends of headgear 44 respectively sharp thinning end, improves and drill through efficiency.
