Description

The liner tube type undisturbed soil soil sample barrel of belt supporting frame

Technical field

The present invention relates to a kind of soil sample barrel, a kind of liner tube type undisturbed soil soil sample barrel of belt supporting frame specifically, this soil sample barrel is used to gather the soil analysis sample of different depth, not being only applicable to scientific research takes a sample with undisturbed soil, also be applicable to the soil test sampling, be applicable to and soil, geotechnological relevant scientific research, teaching and production division.

Background technology

Soil sample barrel is as a kind of collection soil analysis sample, the aid that is used for soil analysis sampling, soil test sampling is used widely by the scientific research relevant with it, teaching and production division, soil sample barrel of the prior art, for example the patent No. is 200410073303.2 formerly patented claim, because its structure is unreasonable, so there are many shortcoming and defect parts, 1., soil sample overcoat press-in device design is unreasonable be in particular in:, a little less than anti-pressure ability, be pressed into and take out difficulty after soil; Although 2. be provided with the horizontal bubble of levelling, there is no horizontal stationary installation, be difficult to realize in actual mechanical process; 3., internal thread drilling rod fixator is connected with the A-frame of support the Fast Installation that is unfavorable for instrument and fixes.

Developed liner tube type vertical compression undisturbed soil soil sample barrel in order to address the above problem the applicant, and applied for patent of invention, number of patent application is 201210403091.4, this soil sample barrel is mainly used in gathering the soil sample of 40cm-60cm left and right, the section larger for the depth ratio that fetches earth fetches earth, as gather scientific research more than 100cm, teaching with undisturbed soil and the soil test soil sample of deep layer more, because manpower is limit, fetch earth more difficult.

Summary of the invention

The present invention seeks to provide a kind of simple and reasonable, easy to operate, time saving and energy saving, it is little that soil sample barrel enters the suffered resistance of soil layer, utilizes screw thread pressurization rotation to press soil sample barrel to enter the liner tube type undisturbed soil soil sample barrel of the soil body, belt supporting frame that soil extracting efficiency is high.

The object of the present invention is achieved like this, this soil sample barrel comprises the soil sample barrel main body, is arranged on the fixed cover on the soil sample barrel main body, be connected to an end on fixed cover with the leading screw of spanner, be sleeved on the leading screw fixator on leading screw, connect the triangle pole on the leading screw fixator, be arranged on triangle pole lower end and the soil sample barrel main body played the disc-shaped base of fixing and position-limiting action.

Described soil sample barrel main body comprises outer soil sample barrel, be arranged on internal lining pipe and the block of outer soil sample barrel inside, described outer soil sample barrel is made of the section of fetching earth, bushing pipe canned paragraph and three parts of block canned paragraph, wherein an end of the close section of fetching earth in the outside of bushing pipe canned paragraph is with an annular protrusion, the upper transition with the centrum shape of the section of fetching earth, the connecting portion of described bushing pipe canned paragraph inside and the section of fetching earth is with a rounding off section, and the outside of described block canned paragraph is with boss and symmetrically arranged two retaining screws of an annular.

Described internal lining pipe is arranged in the bushing pipe canned paragraph of soil sample barrel body interior, withstands on ring-type rounding off section, and the internal diameter of the described mouth that fetches earth is less than the internal diameter of internal lining pipe.

Described fixed cover is made of with connection leading screw end on being connected the fixed cover main body the fixed cover main body, wherein is symmetrily processed with the gap of two shapes in T shape on the fixed cover main body, matches with two symmetrical retaining screws of block canned paragraph outside.Connect on the leading screw end with being connected and fixed the hole.

After ground floor soil takes out, in the time of need to getting the second layer soil below ground floor, by the triangle pole of support leading screw fixator is changed into shorter triangle pole, the soil sample barrel main body changes the soil sample barrel that the fixed cover external diameter is equal to or less than soil sample barrel main body external diameter when getting ground floor soil into and realizes.

The present invention is because the inside in the soil sample barrel main body arranges the plastic inner lining pipe, overcome in prior art soil sample barrel and fallen the soil difficulty, and soil sample can not be near the shortcoming and defect of virgin state, and soil sample barrel is more convenient when fetching earth; Utilize leading screw that soil sample barrel is pressed into the soil body, the outside annular protrusion of the section of fetching earth has reduced soil resistance, overcome when in prior art, soil sample barrel enters the soil body resistance large, the firming effort, soil sample barrel take out from the soil body difficulty shortcoming and defect, have simple and reasonable, time saving and energy saving, the efficient advantages of higher, be and soil, the relevant scientific research of geotechnique, teaching and production division gather pedotheque the first-selection of carrying out the soil sample analysis utensil that fetches earth.
