Abstract
The utility model relates to a kind of shallow-layer used for geological prospecting and manually to fetch earth nested structure, comprises the cover that fetches earth, described in the fetch earth outer wall screw of cover hold cover tightly, hold the lower end of cover tightly with holding ring portion tightly.Described inner side of holding ring portion tightly is with helicla flute, and the lower end outer wall of the cover that fetches earth is fixed with guide pad, and guide pad coordinates with described helicla flute.Structure of the present utility model is simple, reasonable in design, and its functional reliability is high; Adopt and hold the partial closure structure of cover to soil sample tightly, effectively prevent soil sample from departing from the cover that fetches earth, improve sampling efficiency; Holding tightly cover and fetch earth overlap between be helical structure, conveniently hold operation tightly.
Description
Technical field
The utility model relates to geological prospecting apparatus field, particularly relates to a kind of device for thin solum soil sampling.
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 shallow-layer used for geological prospecting rational in infrastructure, easy to use, that efficiency is high manually to fetch earth nested structure.
The technical scheme that the utility model adopts is as follows:
A kind of shallow-layer used for geological prospecting manually fetches earth nested structure, comprises the cover that fetches earth, described in the outer wall screw overlapped that fetches earth hold cover tightly, hold the lower end of cover tightly with holding ring portion tightly.
Further improvement as technique scheme:
Described inner side of holding ring portion tightly is with helicla flute, and the lower end outer wall of the cover that fetches earth is fixed with guide pad, and guide pad coordinates with described helicla flute.
Described guide pad comprises multiple and is arranged in the position up and down of bottom of the cover that fetches earth respectively.
The guide pad being arranged in the bottom of cover bottom of fetching earth is installed on the end slot of the cover that fetches earth.
The described cover that fetches earth, with external screw thread, holds cover tightly with internal thread.
The beneficial effects of the utility model are as follows:
Structure of the present utility model is simple, reasonable in design, and its functional reliability is high; Adopt and hold the partial closure structure of cover to soil sample tightly, effectively prevent soil sample from departing from the cover that fetches earth, improve sampling efficiency; Holding tightly cover and fetch earth overlap between be helical structure, conveniently hold operation tightly.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
Wherein: 1, fetch earth cover; 11, external screw thread; 12, end slot; 2, cover is held tightly; 21, internal thread; 22, ring portion is held tightly; 221, helicla flute; 3, guide pad.
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 shallow-layer used for geological prospecting of the present embodiment manually fetches earth nested structure, and comprise the cover 1 that fetches earth, cover 2 held tightly by the outer wall screw of the cover 1 that fetches earth, and the cover 1 that fetches earth, with external screw thread 11, holds cover 2 tightly with internal thread 21; Hold the lower end of cover 2 tightly with holding ring portion 22 tightly, hold the inner side of ring portion 22 tightly with helicla flute 221, the lower end outer wall of cover 1 of fetching earth is fixed with guide pad 3, guide pad 3 coordinates with helicla flute 221, guide pad 3 comprises multiple and is arranged in the position up and down of the bottom of the cover 1 that fetches earth respectively, and the guide pad 3 being arranged in the bottom of cover 1 bottom of fetching earth is installed on the end slot 12 of the cover 1 that fetches earth.
When use of the present utility model uses, the cover 1 that fetches earth is inserted underground and is fetched earth a little, rotates the press-in underground, lower end of holding cover 2 tightly, fetches earth a little until reach; Cover 2 is held in rotation tightly, and will hold cover 2 cover 1 that relatively fetches earth tightly and screw in downwards, that holds cover 2 lower end tightly holds ring portion 22 tightly under the guide effect of guide pad 3, and the lower end to the cover 1 that fetches earth is drawn close, and the soil sample fetched earth in cover 1 is carried out partial closure, prevents it from spilling; Taking-up is fetched earth after cover 1 and is namely completed soil sampling operation.
Structure of the present utility model is simple, reasonable in design, and its functional reliability is high; Adopt and hold the partial closure structure of cover to soil sample tightly, effectively prevent soil sample from departing from the cover that fetches earth, improve sampling efficiency; Holding tightly cover and fetch earth overlap between be helical structure, conveniently hold operation tightly.
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.
