Description
Technical field
The utility model relates to a kind of soil sampling apparatus, especially a kind of hard soil cutting ring sample sampling device.
Background technique
Cutting ring sample sample is widely used in soil test detection, is to be commonly used to that undisturbed soil (undisturbed soil) experiment is taken to use
A kind of common instrument of sample, soil sample can be used to do the test such as bulk density, moisture content, compression, shearing and infiltration.Now current ring
Knife takes soil that mainly cutting ring is pressed into the soil body using the handle connecting with cutting ring, and the original state soil body is taken out.But above-mentioned ring
Knife takes soil, and there are following disadvantages: when encountering hard soil, cutting ring indentation is difficult；In addition to this, after cutting ring indentation soil, in order to drop
Low disturbance needs to take out cutting ring from the peripheral soil that slowly excavates, not only laborious in this way, but also low efficiency.
Utility model content
The purpose of the utility model is to provide a kind of hard soil cutting ring sample sampling devices.The utility model, which has, to be taken
Cubic metre of earth just, the characteristics of disturbing small and strong applicability.
The technical solution of the utility model includes: a kind of hard soil cutting ring sample sampling device, includes main shaft, main shaft lower end is worn
Saturating base cover is simultaneously threadedly coupled with base cover, and main shaft lower end is flexibly connected with connection component, and connection component is connect with cutting ring, cutting ring
Peripheral precession mechanism is also fixedly connected on main shaft between base cover；The connection component includes upper joint sleeve, upper joint sleeve
Top is flexibly connected through bearing with main shaft lower end, and upper joint sleeve lower part is connect with cutting ring；The peripheral precession mechanism packet
Precession bracket is included, precession bracket is equipped with arc shaped rotary sword, and precession bracket is connect with main shaft；Cutting ring is enclosed in it by arc shaped rotary sword
Side.
In hard soil cutting ring sample sampling device above-mentioned, the blade of the arc shaped rotary sword bottom end is lower than in vertical direction
Cutting ring blade.
In hard soil cutting ring sample sampling device above-mentioned, the connection component further includes lower joint sleeve, on lower joint sleeve
Portion is detachably connected with upper joint sleeve, and lower joint sleeve lower part is connect with connection ring, and connection ring and the annular groove for being set to cutting ring are detachable
Connection.
In hard soil cutting ring sample sampling device above-mentioned, the base cover bottom is also cased with dismountable counterweight ring.
Beneficial effect
The main shaft lower end of the utility model penetrates base cover and is threadedly coupled with base cover, and main shaft lower end and cutting ring activity connect
It connects, peripheral precession mechanism is also fixedly connected on the main shaft between cutting ring and base cover；Peripheral precession mechanism includes precession bracket, precession
Bracket is equipped with arc shaped rotary sword；Cutting ring is enclosed in its inside by arc shaped rotary sword；With this configuration, in cutting ring sample, main shaft rotation
Into, drive arc shaped rotary sword precession, while cutting ring is moved down by main shaft promotion；During being somebody's turn to do, because the continuous precession of arc shaped rotary sword makes arc
The soil of rotation sword inner peripheral is separated, and cutting ring becomes to be more easier when being pressed into the soil enclosed in arc shaped rotary sword at this time；And because
The precession of arc shaped rotary sword does not have an impact substantially to middle part (i.e. at the position of vertical direction alignment cutting ring) is enclosed in it, so cutting ring institute
The structural perturbation of the soil of acquirement is small, the raising of more conducively subsequent measurement accuracy.The cross section of soil is inside enclosed with arc shaped rotary sword
The increase of precession depth constantly reduce until it is interior enclose soil bottom and be cut off be kept completely separate with peripheral soil, the arc of reversion back-out at this time
Shape rotation sword, which removes base cover, can access the soil sample of cutting ring taking-up；With this configuration, so that the taking-up of cutting ring soil sample is without artificial
It is taken out from the peripheral soil that slowly excavates, labor intensity is smaller.To sum up, the utility model cutting ring be pressed into and take out process all more
It is easy to add, laborsaving, thus soil extracting efficiency is higher.
The cutting ring of the utility model is detachably connected with connection component；With this configuration, it can be replaced according to different demands
The cutting ring of different size carries out taking soil, and use scope is wider, and applicability is stronger.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.A kind of hard soil cutting ring sample sampling device constitutes as illustrated in fig. 1 and 2, includes main shaft 1, main shaft 1
Lower end penetrates base cover 2 and is threadedly coupled with base cover 2, and 1 lower end of main shaft is flexibly connected with connection component 5, connection component 5 and ring
Knife 6 connects, and is also fixedly connected with peripheral precession mechanism 7 on the main shaft 1 between cutting ring 6 and base cover 2；The connection component 5 includes
Upper joint sleeve 51,51 top of upper joint sleeve are flexibly connected through bearing 52 with 1 lower end of main shaft, 51 lower part of upper joint sleeve and cutting ring
6 connections；The peripheral precession mechanism 7 includes precession bracket 71, and precession bracket 71 is equipped with arc shaped rotary sword 72, precession bracket 71
It is connect with main shaft 1；Cutting ring 6 is enclosed in its inside by arc shaped rotary sword 72.
The upper end of the main shaft 1 is additionally provided with turntable 8, in order to live spindle 1.
When soil sampling, upper soll layer is first scraped off, base cover 2 is lain against and takes Tu Chu；Turn main shaft 1, main shaft are rotated and are moved down,
The precession therewith of arc shaped rotary sword 72, the soil of its inner peripheral is separated, while cutting ring 6 is gradually pressed into arc shaped rotary sword 72 by main shaft 1
Soil is enclosed in centre, with the increase of precession depth, inside encloses the cross section of soil bottom and peripheral soil junction not
It is disconnected reduce will be filled with until be cut off, reversely screw out arc shaped rotary sword 72 at this time and remove base cover 2 soil sample cutting ring take out to get
The soil sample taken out to cutting ring.
The blade of 72 bottom end of arc shaped rotary sword above-mentioned is lower than 6 blade of cutting ring in vertical direction.Preferably, 72 bottom of arc shaped rotary sword
The blade at end is lower than 6 blade 8-10mm of cutting ring.With this configuration, arc shaped rotary sword 72 is first screwed in soil to separate soil, so that
Cutting ring 6 is pressed into more labor-saving when soil.
Connection component 5 above-mentioned further includes lower joint sleeve 53, and 53 top of lower joint sleeve is detachably connected with upper joint sleeve 51,
53 lower part of lower joint sleeve is connect with connection ring 54, and connection ring 54 is detachably connected with the annular groove 4 for being set to cutting ring 6.With this configuration,
The cutting ring of different size can be replaced, use scope is wider, and applicability is stronger.
2 bottom of base cover above-mentioned is also cased with dismountable counterweight ring 3.Setting counterweight ring pushes down base cover 2, so that base cover is consolidated
It is more stable to determine supportive；Simultaneously further to keep base cover 2 firm, also screw etc. can be used that counterweight ring 3 is fixed on ground.
